    2018 Acadia
  1. He tells me his Buick Regal only has one AGM Battery. Still, to your point, AGM's are more expensive than standard batteries. - Bob
  2. Ahhh. The answer the question with a question trick! I'll tell you, if you tell me first. What data do you have that the current AFM is unreliable? And you did not hurt my feelings. I am just trying to understand your fear. BTW, a friend of mine got a 2018 Buick with ASS (AutoStopStart) and he is like you, in that he is worried about the reliability of the system. Nothing I could say to him would convince him that the system was designed with the 98% user in mind. I, too, plan on keeping my Acadia for a long time and have no fear over AFM. My plan is to keep it for 10 years or more just like I owned my Pontiac Torrent GXP. It was still near mint when I sold it & the guy who owns it now said it has been trouble free. It only had 110k miles on it when I sold it. BTW, I kicked the butt of a new Honda Pilot the other day with my V6 Acadia.
  3. Where did you get that data? I retired 10 years ago & we didn't have that mentality.
  4. AFM (cylinder deact) is only used sparingly on my 2018 Acadia. Plus when it is activated, it is only under very light loads. So the unbalanced loads (do to V4 vs V6 operation) are also very low in comparison to heavy throttle/load conditions. I don't see any long term durability issues there. There made be a bit more duty cycle (switching components) added to the fuel & ignition system due to AFM, but again, I see no reason for concern there. I worked in Powertrain most of my career & have gone thru the "seat of the pants" analysis and don't see an issue. The Engine guys looked at the long term effects of AFM when they run the ADV plan. So maybe the OP can describe why he is worried about the long term durability of systems while having AFM active.
  5. Thanx for the post & pictures. Very helpful. I decided to install the recommended license plate bulbs. I was disappointed to find that the original bulbs already had some corrosion on one contact wire on side of the bulb. The bulb wire on one bulb had nearly corroded off. It took some doing to clean the socket contacts. I put some Noalox inside the socket & on the new bulbs. I then coated the sockets O rings with some silicone grease. Even with the effort, I am not convinced that electrical contacts are secure. I expect to have to replace the socket in the future. I hope Springhill has addressed this issue & is now including anticorrosion grease to these bulbs and sealer on the O ring. My '18 Acadia has ~12000 miles & I live in SE Michigan. -Bob
  6. 2018 Acadia Transmission Manual Range select

    Apparently there is a bulletin out on the shifter. The dealer has my car now & he tells me the shifter is broken in two areas. The shifter is either being redesigned or is already. But he has no idea how long it will be to get a new shifter assembly . Could be weeks as it is back ordered.
  7. 2018 Acadia Transmission Manual Range select

    Low range is a Federal requirement. NHTSA would view this as a safety issue. I use it frequently (when it works). Apparently you haven't been down Mt. Haleakala or Mt. Washington. Low range is a must there. Guess you need to drive more than just 45 years. Thanx for the helpful answer.
  8. 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
  9. I am ready to take my '18 Acadia back for a refund. The door chime is insanely loud and I am almost deaf! And yes, I have the chime volume turned all the way down on the Bose entertainment system. I have a sound level meter & plan on measuring the level. As a retired GM Engineer, I can't imagine how the GMC engineers would permit such a continued mistake. I looked thru this forum & online & this has been a constant complaint item for years. It is what we used to call a "Perennial" back when I was working. It has to be a continued and significant warranty cost to GM. I would like to contact the Acadia Chief Engineer and ask her/him what they were thinking & how do I get it fixed. I know there are bulletins out there for older vehicles. Is there a bulletin for the 2018 that I can reference when I take it back to the dealer? Thanx - Bob
