Hey! So, I'll give you the quick history... Over the last year we've replaced 3 coil packs. It started with a miss and the dealership recommended a top engine clean and repair of an engine mount. We did that and it didn’t fix it. So they changed one of the coil packs and that did fix it. Then a few months later the miss appeared again and a different dealership replaced another coil pack, at that time at the different dealer they also changed the spark plugs for the other cylinders on that bank (1,3,5 ), the coil pack they changed was #3. Then right before Christmas another coil pack. And now it started missing again and this time I took it to dealer and they said it was the #3 and #4 coil packs. Which the #3 was just changed in July. That one is covered under the GM 2 year parts and labor warranty and at the local dealer we go to they said they didn't record which coil packs they changed before ??. But I had record from the other dealership that it was #3 for the one in July. My question is, what is causing these failures? To have the dealer fix them is like 400 each time! I'm probably going to do the fixing myself from here on if this keeps happening. I just want to understand why it's failing? Are they not gapping the plugs right? I would imagine they are checking for leaks and moisture once they are in there? I’m starting to not have any faith in them and want to understand everything better so I can be more knowledgeable and prepared for our next conversation at least.

John Goreham Contributing Writer, GM-Trucks.com 2-19-2019 GMC has updated the Acadia for 2020. The biggest news is the drivetrain lineup. The familiar 2.5L I-4 and the 3.6L V-6 engines remain standard or optional equipment for the 2020 Acadia dependent on the trim level selected, but GMC is adding a new 2.0-liter turbocharged engine to the lineup. The engine is has a GMC-estimated 230 horsepower (172 kW) and 258 lb-ft of torque (350 Nm). The turbo is a dual-scroll design developed to enhance low-speed torque delivery. Peak torque is available from 1,500 to 4,000 rpm, for an exceptional feeling of responsiveness, which means that in normal driving more torque will be available than from the V6, which has 271 lb-ft, but at a much higher RPM point. GMC is also adding a "tripower valvetrain" that complements the turbocharging system to make the most of the engine’s available power at all speeds. The turbo four can actually run on just two cylinders under light loads courtesy of GM's now ubiquitous active fuel management. It will be interesting to see how the fuel economy numbers pan out for this new turbo. The engines are coupled to a new 9-speed automatic. GMC has removed the gear shift lever and instead, the Acadia now has Electronic Precision Shift, which enables more storage room in the center console by replacing the conventional transmission shifter with an electronically controlled gear selection consisting of intuitive push buttons and pull triggers. GMC specifically mentioned that all of the engines have auto stop-start, but there is a switch to turn off this annoying feature most drivers don't like. GM did not mention if the system will stay off. In addition to a new interior style, the 2020 Acadia has a lot of new tech improvements. Here they are in bullet-point format: - Personal profile allows users to tailor the infotainment system to their preferences, including audio, available navigation (requires subscription to compatible Connected Services) and climate settings, and even transfer those preferences to another GM vehicle with a compatible infotainment system. Up to four profiles can be assigned to the system and they can be assigned to the Acadia’s key fobs, automatically resetting the preferences for the incoming driver. - All-new Navigation interface with “one shot” destination entry feature, improved Route Guidance functionality and personalized settings. - Connected Navigation offers real-time updates, as well as Predictive Navigation and additional information provided by a cloud database. (Feature requires a Connected Navigation trial or subscription and connectivity.) - USB-C ports. Two new USB-C charging ports are integrated in the front and rear of the center console. That brings the number of ports in the Acadia to five, including a USB-A charging port for the third-row seating area. - Next-generation, 15-watt wireless charging (available). - High Definition Rear Vision Camera upgraded to digital (standard on SLT, AT4 or Denali and available on SLE). - New Rear Camera Mirror available on Denali. - Head-Up display (later in the model year) An AT4 trim will have all-terrain tires, standard AWD, and some design cues to lure those who want an off-road look. The new 2020 GMC Acadia goes on sale this fall. It will be assembled at GM’s Spring Hill, Tennessee, assembly plant.

John Goreham Contributing Writer, GM-Trucks.com 10-9-2018 U.S. News & World Report is run by and staffed by colleagues of GM-Trucks.com. Each month they scour the best deals in the country to list out the most notable. This month, GM products earned spots on two of their lists. The 2018 Acadia is on both the 7 Best Cars to Buy Now and also October's Best New Car Deals. U.S. News Autos reports that GM is offering $4,000 cash back on that popular model. The 2018 Chevy Tahoe appears on the second list for its special offer of $3,000 cash back if buyers finance through GM.

I'm very frustrated about how GM denied an extended warranty coverage case on a well known production issue of their 2008 GMC Acadia (and many other models, see list and bulletin). Up until now I was very happy with my car and even considered upgrading soon but the way GM handled and communicated my case is careless and completely unacceptable. On Aug 6, while literally on the way to the airport for my family vacation to Europe, the check engine light came on and we had to take the airport shuttle instead. After returning in September I had the car towed to the dealer who diagnosed a faulty 35R transmission clutch wave plate. A quick internet search turned up service bulletin #14404 (https://gm.oemdtc.com/TSB/SB-10057962-6560.pdf) describing this issue as a common and well known defect in many early models (including mine), as a matter of fact grave enough to extend the warranty to 10 years and 120,000 miles. I called GM customer engagment who bluntly denied the warranty because it had expired 2 weeks prior the diagnose. This is upsetting because the mileage on my Acadia is way below 120,000, the problem originated long before the expiration date and there wasn't any communication that would have notified me of that issue or triggered a sense of urgency to bring in the car before going on vacation. I strongly believe that it is GM's responsibility to rectify this well known issue under the extended warranty conditions given the above described circumstances. I'm happy to provide further evidence (plane tickets, diagnosis report) and look forward to your reply and a resolution to my problem within the next 3 days.

I've a 2018 GMC Acadia. It is a FWD 3.6L/6T70. Recently, I've not been able to move the shift lever to Low ranges. It was intermittent at first & today I was not able to shift it into low range at all. Wondering: if anyone else has experienced this?, Fix?, Bulletin? This is a potential safety issue. Thanx Bob

John Goreham Contributing Writer, GM-Trucks.com 6-12-2018 In a new round of testing by IIHS, the 2018 GMC Acadia topped all domestic brands and also top-sellers the Honda Pilot and Toyota Highlander in an important passenger-side safety test. The Acadia scored Good overall on the small frontal overlap test which simulates the vehicle hitting a pole or another object with just the front corner of the vehicle. The Ford Explorer's airbags malfunctioned and the Jeep Grand Cherokee saw big cabin intrusion due to a weak crash structure. Both scored the lowest possible overall grade. The GMC Acadia joins the Kia Sorento and VW Atlas in earning the top overall score of Good.

Zane Merva Executive Editor, GM-Trucks.com 6/5/2018 Two years into the new model and the GMC Acadia is more popular than ever.

John Goreham Contributing Writer, GM-Trucks.com 3-23-2018 GMC says that about one in five of its customers spends money on aftermarket exterior treatments. Rather than see those dollars going elsewhere, GMC is offering a variety of special exterior treatment editions of its vehicles. The latest is the GMC Terrain and Acadia Black Editions. GMC sees the Black Editions as OEM black-out treatment vehicles with a more distinctive personality. Both new styles launch this summer. “The new Terrain and Acadia Black Editions perfectly capture the identity of the GMC brand by offering a bold and confident exterior appearance,” said Duncan Aldred, vice president of Global GMC. “They give our customers more choices within the premium SUV segment to distinguish their vehicle and themselves.” Terrain Black Edition (Available on SLE & SLT) Features 19-inch gloss black aluminum wheels Darkened grille insert and black surround Black mirror caps, roof rails and additional exterior accents Black exterior model and trim badging Offered in five exterior colors: Ebony Twilight Metallic, Summit White, Graphite Gray Metallic, Satin Steel Metallic and, new for 2019, Sedona Metallic** Acadia Black Edition (Available on SLT) 20-inch machined aluminum wheels with black accents Black grille insert and black surround Black headlamp and taillamp details Black mirror caps, roof rails and additional exterior accents Offered in five exterior colors: Ebony Twilight Metallic, Summit White, White Frost Tricoat and, new for 2019, Dark Sky Metallic and Smokey Quartz Metallic

George Kennedy Contributor, GM-Trucks.com 7/14/2016 It seems like everything is going “biggie-biggie” these days. From Big Box Stores to massive iced coffees, everything has to get bigger to match our tastes. Cars, trucks, and SUVs are no different, with models growing every time they are redesigned. We automotive experts call this “generation bloat,” and it seems like it is inevitable when a new vehicle comes out. But GMC did the unthinkable when it redesigned the new 2017 Acadia SUV, and actually made it smaller. The second generation of GMC’s full-size (available) three-row crossover is 7 inches shorter, 3.5-inches narrower, and has a 6-inch shorter wheelbase. GM says this new footprint, which is based on the C1XX platform (which will underpin the new Cadillac XT5), is 740 pounds lighter than the outgoing model and has a tighter turning radius. Put it next to the first generation Acadia and it appears considerably smaller from the outside, but what it loses in size, it gains in style. The first-gen’s styling was inoffensive enough, but the Lambda-platform vehicles had rather bulbous styling–not exactly in line with the brawny “Professional Grade” image that GMC tries to portray. But the new-look Acadia has a well-defined visual character, with an upright grille and brooding headlights. Thankfully GMC left off the indented faux fender flares of the Terrain. Despite the smaller footprint, the Acadia retains a lot of its cabin space. You sit slightly closer to the passenger beside you, but first and second row passengers have plenty of head- and legroom. The Acadia is available as a 5-passenger (delete 3rd row), 7-passenger (3rd row with 2nd row captains chairs) or 8-passenger (2nd and 3rd row benches) configurations. The second row features GMC smart-slide seating. One handle, one motion slides seat forward for easy access to the 3rd row. GMC says customers asked for more usable space and lots of places to put things, so they delivered, with plenty of cupholders and pockets for all your gear and devices. The re-proportioned styling also resulted in improved visibility, so you’ll use the standard backup camera as an aid rather than a crutch. The weight loss also gave GMC room to employ technologies like lightweight sound deadening, contributing to a quieter cabin A GMC model would not be complete without a Denali trim, and the Acadia does not disappoint. True to form the Acadia Denali features 20-inch wheels, hands free power liftgate, and the usual slathering of chrome to the exterior. New for 2017 is the Acadia All-Terrain. For starters, it loses the 3rd row, resulting in 79 cu ft. of storage space. The chrome of the Denali replaced by black accents, for a more menacing look. But the real development of the All-Terrain is beneath the skin, there an Active Twin-Clutch AWD System transfers torque from front to rear or from left to right. Our sources at GMC say this model is targeted at Jeep Grand Cherokee customers and its capability seems to back that up. You won’t be crossing the Rubicon trail in one of these, but the AWD can get you to the ski loge, camp site or out on to the beach with ease. The Acadia delivers a ton of standard and available technology to you’re your life easier. The automatic rear lift-gate opens simply by having your keys in your pocket swinging foot under the rear bumper. This is crucial when you’re hands are fully of groceries and can’t reach your keys. GMC has also baked a whole host of new connectivity into the Acadia, highlighted by three new apps that are accessed via the large available touch screen. The first one is Glimpse, which allows users to send their location to friends. Other Glimpse users can see you on a map, which is very handy when picking up someone from a busy airport terminal. Next up is At Your Service, which is an OnStar-type app that lets you search local businesses and it will bring up relevant deals and coupons. Finally, there’s the Weather Channel app. Seems simple enough to have a weather app on your smartphone, but this app layers on top of navigation, and will give weather related warnings and adjust travel times accounting for the weather. The base engine is a 2.5-liter inline-4 making 194 hp and 190 lb ft of torque. This engine features auto-stop-start and is good for 21 miles per gallon city, 25 highway, 23 combined (for AWD) The more powerful engine (and likely more popular choice) is the 3.6-liter V6, developing 310 hp and 272 lb ft. This engine has Active Fuel Management, which turns a V6 to a V4 when less power is needed. This engine returns fuel economy of 18 city, 25 highway, 20 combined (AWD). Power is sent through a 6-speed automatic transmission to the front wheels or available all-wheel drive. Acadia features Traction Select, which adjusts throttle response, transmission shift points, steering feel, and suspension stiffness (if equipped). You can chose from Sport, Snow, all-wheel drive, off-road, and trailer/tow drive modes, all with the push of a button. In Sport mode, the Acadia has brisk acceleration, but we found the 6 speed automatic sometimes had trouble deciding which gear to stay in. This could be chalked up to pre-production teething. Steering was well-weighted and the suspension was responsive, while still soaking up bumps in the road. An innovative feature is the available Tow Vision Camera. All models have the backup camera, but the Tow Vision Camera offers unique angles and guidelines perfectly suited for towing up to 4,000 lbs. (when equipped with V6 and towing package). The Acadia also has all of the latest advanced safety tech, including Lane Keep assist, front park assist, pedestrian detection, front auto braking, (low speed front auto braking) adaptive cruise, and forward collision alert. The 2017 Acadia is also equipped with Rear Seat Reminder: when you close doors and turn off car, there will be five reminders to look back into the rear seat. This is to prevent parents from leaving kids in the back seat on a hot day. This feature is defaulted on, but can be toggled off in the settings menu. Base MSRP for the 2017 GMC Acadia is $29,995 for the SL trim, $33,375 for the SLE-1, $39,275 for the SLT-1, and $45,845 for the Denali. The pricing suggests the Acadia wants to move upmarket in the large SUV space, and the svelte new look actually makes sense in the process. Acadia buyers seeking a premium vehicle with upscale features had more than enough space, but needed more luxury. The new Acada has that luxury in spades, and trims the fat, resulting in a stylish, well-equipped SUV with head-turning looks and a cabin that will be a pleasure to sit in for hours and hours of freeway or back road alike.

Zane Merva Executive Editor, GM-Trucks.com 2/16/2016 GMC recently took the wraps off the completely new, 700-lbs lighter, and more fuel efficient midsize Acadia. Now we can add "cheaper" to the list as well. The brand announced today that when it goes on sale next spring, the Acadia will cost nearly two-thousand dollars less than the 2016 model. Standard equipment on the base model SL includes Apple CarPlay and Android Auto. The brand will continue to offer front-wheel-drive and all-wheel-drive variants in SL, SLE, SLT, All-Terrain, and Denali trims. A new 2.5L four-cylinder engine is standard and includes stop/stop technology. An optional 310-horsepower V6 is available for those owners who want more power or will use their Acadia to tow. GMC expects a V6 FWD Acadia to get nearly 25 MPG on the highway and a FWD 2.5L Acadia to achieve 22MPG in the city. Full fuel economy numbers were not released.

John Goreham Contributing Writer, GM-Trucks.com 1/21/2016 The recently revealed 2017 GMC Acadia gets smaller, lighter and more fuel efficient for 2017. With such close model alignment between GMC, Buick, and Chevy one would assume that the 2017 models of the Traverse and Enclave would follow suit. However, Automotive News (AN), a publication we hold in very high regard, is reporting that it thinks otherwise. This is based partly on a short comment by GM's Mark Reuss (who our own Zane Merva interviewed recently and who was kind enough to spend some time with this writer chatting off the record). In the context of whether the Chevy and Buick large crossovers would follow this smaller design of the GMC, Reuss is quoted as saying “The brand separation in size and mission and the positioning of these vehicles has never been more differentiated.” This makes Automotive News think GM will not keep the three amigos aligned. AN further speculates that GM will create a new crossover to slot in between the Equinox/Enclave. The problem with that logic is that Buick has just launched the new Envision, which is smaller than the Equinox by a little bit. Our take on the crossovers from GM is that they will be changing and they will be more aligned with the competition's model sizes. It is too early to tell how it will all shake out.

John Goreham Contributing Writer, GM-Trucks.com 1/12/2016 GMC has announced an all-new 2017 Acadia that is about seven inches shorter in length, three inches narrower, and four inches lower in height. The new Acadia is an amazing 700 pounds lighter than the outgoing model. Downsizing a vehicle at GM is an extremely rare occurrence. GM is also introducing a new 2.5-liter four-cylinder engine and revised, more efficient and more powerful 3.6-liter V6 for the Acadia. The goal here is obviously to make the Acadia more fuel efficient. However, the vehicle also has new safety technology and a new All-Terrain option, meaning this is a crossover that will continue to be a serious contender in its segment. The 2017 Acadia will still offer third-row seating in most trims. Five, six, and seven-passenger seating arrangements are available. Usability is still an emphasis, and the second row of seats will fold flat for cargo hauling. Rick Spina, executive chief engineer for compact and crossover SUVs at General Motors, said, “It’s a vehicle that offers the functionality Acadia is known for while delivering big advantages and balance to customers’ everyday lives.” Acadias with AWD will have an off-road mode, but the new All-Terrain trim will replace that with an All-Terrain setting that has enhanced hill-climbing abilities. GMC is emphasizing its Active Twin Clutch all-wheel drive technology. The All-Terrain is only to be offered in five-passenger seating if we read GM’s specifications correctly. Trailering up to 4,000 pounds will be possible with the Acadia when equipped with its trailer package. The mid-size crossover segment is all about family needs, and thus, the new 2017 Acadia will have a long list of passive and active safety features. GMC specifically designed the new Acadia to do well on the IIHS’ small frontal overlap test. With its advanced active safety suite, the new Acadia should earn the Top Safety Pick Plus rating. Here is a list of some of the safety features that will be available: • New Front Pedestrian Braking • New Low-Speed Forward Automatic Braking (standard on SLT-2 and Denali) • New Forward Automatic Braking (available on Denali) • New Following Distance Indicator • New IntelliBeam automatic headlamp high-beam control • New Surround Vision camera system • New Safety Alert Seat • Forward Collision Alert • Lane Keep Assist with Lane Departure Warning • Lane Change Alert with Side Blind Zone Alert • Front and Rear Parking Assist. Clearly GMC wants to continue the success of the Acadia. Downsizing is an interesting move by the company. There have been no fuel economy projections yet for AWD vehicles but expect significant improvements over the 2016 model.

John Goreham Contributing Writer, GM-Trucks.com 1/6/2016 General Motors is recalling 2,633 Acadia, Traverse, Enclave 2016 models all made at the Lansing Michigan plant. The affected vehicles could have a defective weld in the third-row seat assembly that is a safety concern according to NHTSA. The welds were applied during November from the 6th to the 12th of the month. A few days before that the Union that represents the line workers held a vote on the new contract. It narrowly passed. 43% of the workers at the plant voted against it. The period also coincided with a holiday (Veterans Day) and a weekend. This is almost certainly a coincidence. Recalls happen so often now, and often to so few vehicles it is hard to know what we should highlight. GM also announced it is recalling 90 (yup, just 90) 2016 Silverados and Sierras because a mounting stud for an airbag sensor was improperly positioned during assembly. All 90 were built on October 13th and 14th. Again, this was during the period of the voting for the new contract, in this case just before the vote. The defect also occurred on the Tuesday and Wednesday following a Monday holiday, Columbus Day. You can check right here at this link to see if your vehicle is affected by either recall.

I just wanted to share my experience with my OGM1 navigation system. I just got a 2012 Acadia and wanted a nav system for it. I did my research and got an OGM1 from Walt at ADCMobile. He doesn't disappoint with his level of service and great install notes and videos. Apparently there is a known issue with cars that have a separate rear audio control. The problem is that when the rear is turned on by someone in the back seat, the audio that was playing over the cabin speakers goes silent until the rear is turned off again. I found this very frustrating. Walt already had a firmware patch for me to try. Something to do with a tweak to the RSE. After banging my head a few times and repeating, still no luck. Walt took the problem to the guys at Advent to see what they thought. First thought was to have me try again, so I did. After another unsuccessful attempt, the Advent guys really rolled up their sleeves and came up with a special firmware fix just for my situation. As they wrote: "We have been working non-stop to figure out the problem. It all has to do with CAN code , timing of the command, and a very specific wave length of a pulsed command. From what we have learned it seems that these can vary" I just gave it a try last night an eureka! Now everything is working perfectly, rear audio controls and all. For a while I though I was going to be out of luck, but Walt and the guys at Advent really came through. Thanks guys! One question, if anyone knows. If a new firmware update comes out, will I lose my special rear audio fix again? Thanks again! Amazing work. Very glad I picked-up an Advent.
