Dropped off my truck today for the fuel tank replacement, right rear factory 20" rim asking for too much tape weight (3.25oz) just that one wheel, and the vibration issue at 75-80mph/ center seat counsel shaking. That's the only issue I'm having and hope they find a solution but with 711 pages of GMC/ Chevy having vibration issue I doubt it... I've read it all, tourqe converter, drive shaft replacement, rims and tire replacement, ring and pinion I believe, clamps on the leaf spring helping out, axle shaft out of specs, replacing rear end with yukon rear end, **** the list goes on and on. I like my truck a lot, and I would love to keep it for years to come but driving on a long road trip and avg 75-80mph will be a pain in the ass... One of my old friends who still works for GM, I asked him about this issue and he knows about it. He ordered a driveshaft for the customer and still had the vibration issue with no fix, he also drove a loaner vehicle which also has the same issue! Did he fig it out, sadly no. But he as a GM tech knows about the vibration issue. GM really screw up on this issue and continued to sell it with the same problem, 2014, 2015, 2016, and also read 2017 still vibrate. Hope I'm wrong but I don't think my dealer is going to figure it out and No Problem found or unable to duplicate the issue which is bs.

Well folks, I did it. After all the failed attempts at the Chevy dealer I traded it in for a 2015 Ram 1500 Larame. I have to agree with the other folks on here that have done the same thing, it was th

Apparently you and the other customer reps don't care. If you or GM would care y'all would put more effort in the matter. Just coming on the forum and stating the same repetitive posts and being a 3

Well I have some good news and bad news about my truck vibrations. Good news is that my truck has a significantly less vibration at speed. The bad news is my truck has significantly less vibration. Fo

Just got back from a short road trip yesterday. 4 hours to Denver, stayed a few days and 4 hours home. She shook all the way at 70 mph. Sometimes the poor condition of our Colorado roads would mask it but in the southeast corner of Denver Metro the roads are pretty good.

 

Funny thing, set the cruise at 69 and its pretty good, bump it up to 70 and she's a mess. Pass a car up to 80 and its really bad. I guess im getting old but 69 in a 65 is ok for me. It would be nice to move the shakes up to 80 though.

 

Love the truck though. Still one of the best looking trucks on the road. I'm seeing more and more 2016-17 Silverado LTZ's with paint matched grilles. They are growing on me.

 

My wife didnt mention the shakes this trip, she must be getting used to it or doesnt want to engage my car problem OCD. Knowing it might end up with a whole day at a dodge dealer. She did mention how much better this new truck rides over big bumps and overall compared to my GMT800 CCSB. That thing was a wet noodle.

I'm one who had some success w/truing the axle flanges a few months ago. Shaking badly again and it's kind of odd how it started again. Heading back to Phoenix from Lake Mead (Vegas) and stopped to get gas in Kingman. Driving fine before the stop, aggressive shaking afterwards. in fact, it was pulsating through the steering wheel, similar to what Red October sounded like to Jonesy before he sped up the tape to 10X speed. Vibrating on, vibrating off, etc.

 

Wheels balanced and road forced again at Discount tire. 3 wheels 3/4 oz out, 1 was just 1/4 oz. Road force on the rear tires were dang near perfect, but front 2 were .33 and .34 out. I'm not sure if this means inches...they didn't give me a lb reading. Anyone have insight? They said that they don't consider a tire "bad" until .50. I'll have a more detailed conversation w/them once I have more time.

 

Edit: The only improvement made was the pulsing got eliminated. Shaking still there.

Any improvement after the balance? Stock Tires and Stock Wheels?

 

I just contacted a Lemon Law Lawyer and they stated that they will be taking on my case... They also said I'm the 3rd Silverado with vibration issues TODAY. I know nothing here is new but come on already. I really don't want to go to a different brand but I don't know what to do at this point.

Woops. I edited my post above. No real improvement, but the pulsing aspect of the shaking was eliminated after my visit to Discount Tire. Vibes are back and more constant.

Well I got 3 new tires as I mentioned earlier in this hellascious thread. I thought my truck was better but the ride home was horrible. Vibrations on every road surface including new blacktop. I must say that this is the most expensive vehicle I have ever bought and it is by far the worst riding I've been in... my last truck was an 05 Dodge Ram 2500 with over 170k miles and it drove like a Cadillac compared to this. I also own a 2000 TransAm with a road race suspension. , roll cage. All aftermarket from front k member to Strange rearend and it rides nicer than my 2016 professional grade piece of $!&+

Sorry. Off rant for now

Congratulations, you will love your Platinum! It has features you can't get on a Silverado, or Sierra, like Adaptive Cruise Control, Blind Spot Monitors, flat rear floorboard, and rear HVAC vents, on and on! What engine did you get? I have the Coyote 5.0L V-8 in my Platinum.

Yeap, Coyote 5.0L and it is much better than I thought it would be. Pulled 5,000lb. load around today and it didn't even seem strained at all. The transmission seems much better than what was in the Silverado, certainly smoother and isn't constantly hunting for a gear.

 

Welcome to the Club my friend. Instead of a Platinum I went for a Fully Loaded Lariat with virtually every package available, you'll enjoy it! post a pic of her

Absolutely loving this truck. I can't believe I waited so long. I wanted a Tundra but couldn't find exactly what I wanted. I now know the F-150 was the better choice for me anyways.

 

Wish you all the best at solving this beast. It seems all of the brands have some issues, just got to decide what you can live with. I couldn't live with the shaking any longer.

I've had my 2015 CCSB, 4x4, 5.3 LTZ for three weeks and it turned into a vibrator yesterday. Only had 5200 miles on it when I bought it.

 

It went from the smoothest vehicle I have ever owned to a vibrating mess. About a week ago I started feeling vibrations in the gas pedal. Nothing major just a minor annoyance. I get back from Nashville last night and drive it home from the airport and I started noticing a side to side vibration in the steering wheel at speeds between 65 and 75. It got worse at higher speeds.

 

I drove it on a 40 mile round trip today and it was worse. I've driven that same route numerous times and never had an issues. So I know it isn't the road.

 

I have an appointment Thursday at the dealership to have it looked at. Fingers crossed.

This just scares the $( out of me. 2016 Yukon owner with no buffeting or vibration, just low speed booming like (I'm convinced) everybody has to some degree. Thinking of moving to a Silverado or Sierra but damn, you have no way of knowing is one day it becomes a vibrator. I've been a Chevy/GMC guy as of late but I just can't see myself buying one. They sell so damn many of these things that it is hard to believe it occurs that frequently. But a random lemon law lawyer getting 3 new cases in one day is just f'd up.

 

I may need to look closer at a Titan or Ford.

I have a question for all of the guys out here who are mechanically inclined. Would it be possible to remove the rear drive shaft put in in 4x4 and drive to eliminate drive shaft and rear end as cause of vibes. If still present, reinstall shaft, then take out front shaft to eliminate front shaft/diff as cause? I'm almost positive this can be done but not sure what you can use in rear of trans to stop spillage of atf and also front of transfer case. Any trans gurus in this thread?

The front should be easy, flange to flange IIRC. Rear is a little more difficult, I remember the Dodges had a plug for doing this that was just a chunk of plastic.

Thanks. I'm going to do some research. A friend told me that you can just use a yolk in trans but I don't see how it would fall out

Yes it is possible and is one of things the dealer is suppose to try when troubleshooting the issue as outlined on page 3 here:

 

http://gm.oemdtc.com/753/vibration-analysis-and-diagnostic-2014-2015-chevrolet-silverado-gmc-sierra

 

"For 4WD Trucks, remove the rear propeller shaft, seal output shaft and drive the vehicle in 4WD. If the vibration is gone, the rear prop shaft could be the problem."

 

My dealer ignored my request to go through these steps...

I believe, somewhere in the past 712 pages of posts, that someone tried this (at least the front shaft) and it did not fix his problem. This doesn't surprise me since both 2WD and 4WD trucks appear to have the problem.

Now, 07SoftTail claims he fixed his by having his rear drive shaft trued and balanced, but others have also checked their driveshaft and it was fine.

There was also (again a few pages back) talk that the rear axle flanges were badly machined and you could clearly see that they had a bulge on one side.

If you go back through all the pages, you will find that these and many more things were already tried. Some helped for a few people but not others. It seems there is not necessarily one specific problem that you can pinpoint for all trucks.

      2027 3.0l - ordered

      By Jus Cruisin · Posted

      I had a new engine installed with under 5,000 miles. It shut off coming around a residential street corner and wouldn't restart. Dealer indicated it seized. New one has been fine since with 10,000 miles on the replaced engine. Annoying but I was given a loaner for the 5 weeks it was down. I won't go with the 6.2l gasser so it's 3.0l again. I love the economy and it tows my enclosed car trailer just fine.

      Lesson relearned on basic diagnostics...

      By calgator73 · Posted

      Coming back from towing a car to my daughter in Nashville truck started making a screaming noise from underneath.  Pulled over placed in park and sure enough whining noise from underneath.  Dropped at the dealer fearing new tranny or another front pump/cover replacement.  Service writer said it sounded like the tranny too...  Well $300, new idler and a belt all is good.  Pop the hood and give a listen. lol  Now I'm telling dealers I'm no longer interested in a new truck.

      OIL CONSUMPTION

      By newdude · Posted

      HD uses the 6.6 gas.   Oil consumption while heavy working is considered normal.  1 quart per 100 gallons of fuel is the normal rate above 8600lbs GVWR.  If more than that, it is considered excessive.   They will have to perform an oil consumption test using the guidelines in TSB 03-06-01-023J.     Information on Engine Oil Consumption Guidelines All engines require oil to lubricate and protect the load bearing and internal moving parts from wear including cylinder walls, pistons, and piston rings. When a piston moves down its cylinder, a thin film of oil is left on the cylinder wall. During the combustion process, part of this oil layer is consumed. As a result, varying rates of oil consumption are accepted as normal in all engines. Oil Consumption Oil usage has a direct relationship with the amount of fuel used. The harder an engine works, the more fuel and oil it will use. Therefore, oil usage as a factor of fuel usage is a more accurate indicator of acceptable oil consumption levels than vehicle mileage for vehicles at or above 8600 GVW. The accepted rate of oil consumption for gasoline engines in vehicles at or above 8600 GVW is 1 liter (1 qt) within 400 liters (100 gallons) of fuel used. This rate only applies to vehicles under warranty, maintained in accordance with the appropriate maintenance schedule, driven at legal speeds and within design intent of the vehicle. Many factors can affect an owner's concern with oil consumption. Driving habits and vehicle maintenance vary from owner to owner. Thoroughly evaluate each case before deciding whether the vehicle in question has abnormal engine oil consumption. Gasket and External Leaks Inspect the oil pans, engine covers, and the engine oil cooler for leakage. Inspect for oil leakage into the engine coolant. Improper Reading of the Oil Level Indicator (Dipstick) The vehicle must be parked on a level surface to obtain accurate oil level readings. Verify that the dipstick tube is fully seated in the block. When checking the oil level, make sure the dipstick is wiped clean before taking an oil level reading and fully depress the dipstick until the shoulder bottoms out on the dipstick tube. The dipstick should be the proper part number for the engine/vehicle that is being checked. Not Waiting Long Enough After Running Engine to Check Oil Level The vehicle should be allowed to sit for at least 15 minutes, after the engine has been shut off, before taking an oil level reading to assure the oil has had enough time to drain back into the crankcase. In order to ensure accurate results, the temperature of the oil should be close to the same temperature as the last time the oil level was checked. Improper Oil Fill After an Oil Change Following an oil change, verify that the proper amount and type of oil was put in the engine and that the oil level on the dipstick is not above the full mark or below the add marks. Refer to the Owner's Manual or Service Manual for information on recommended oil quantity, viscosity, and quality. High Speed or High RPM Driving Continuous driving at high speeds/high RPMs may increase oil consumption. Because this may not always be an everyday occurrence, it is hard to determine exactly how much the oil economy will be affected. Towing or Heavy Usage Towing a trailer or hauling additional weight will increase oil consumption. Large frontal area trailers will further increase the work required from the engine, especially at highway speeds, and thus increases the rate of oil consumption. PTO Operation Operation of a PTO will increase fuel and oil usage, as the PTO driven accessory uses engine power to operate. Crankcase Ventilation System Verify that the positive crankcase ventilation (PCV) system is operating properly. Blockages, restrictions, or damage to the PCV system can result in increased oil use. Oil Dilution from Condensation On vehicles that are usually driven short distances, less than 8 km (5 mi), especially in colder weather, condensation generated from cold engine operation may not get hot enough to evaporate out of the oil. When this occurs, the dipstick may indicate that the oil level is over-full. Subsequent driving on a trip of sufficient length to enable normal engine operating temperature for 30 minutes or more, in order to vaporize excess moisture, may give the customer the impression of excessive oil consumption. Engine Temperature If an engine is run at overheated temperatures (see Owner's Manual or Service Manual) for more than brief periods, oil will oxidize at a faster than normal rate. In addition, gaskets may distort, piston rings may stick, and excessive wear may result. Verify that all cooling system components are in proper working order. Engine Wear Piston scuffing, excessive piston-to-wall clearance, tapered or out of round cylinders, worn, damaged or improperly installed valve guides, seals and piston rings will all cause an increase in oil consumption. Measurement of Oil Consumption Engines require a period of time to BREAK IN so that moving parts are properly seated. Therefore, oil economy should not be tested until the vehicle has accumulated at least 6400 km (4000 mi). An exception would be allowed only if an engine is reported to be using more than 0.946 liter (1 qt) in 1600 km (1000 mi).   Verify that the engine has no external leaks. Repair as necessary. Verify that the engine is at normal operating temperature (see Owner's Manual or Service Manual). Park the vehicle on a level surface. Wait at least 15 minutes, after the engine is shut off, before checking the oil level to make sure that most of the oil has had time to drain back into the crankcase. Check the oil level and record the vehicle mileage, date, and exact oil level on the form included in this bulletin. Next ensure the oil level is at, but not above, the full mark on the dipstick. add oil if necessary. Also ensure the proper viscosity and quality oil are being used as recommended in the Owner Manual Ask the customer once they have consumed 100 gallons of fuel schedule an appointment and return to the dealer for inspection. If the final evaluation shows that the engine uses more than 0.946 liter (1 qt) in 379 liters (100 gallons) of fuel used, follow the published symptom diagnostics as described in the appropriate Service Manual. If the oil consumption test shows that the engine uses less than 0.946 liter (1 qt) in 379 liters (100 gallons) of fuel used, explain to the customer that their engine meets the guidelines for oil consumption.

      OIL CONSUMPTION

      By RSTRICK · Posted

      I have a 2024 Chevy Silverado 2500 with the 6.2 liter engine, Vin: 2GC4YME79R1273849, with 27,437 miles. Recently we took a trip from Candor, NY to Townsend, TN pulling our fifth wheel, when I got close to the Townsend, TN area The truck gave me a message of low oil. I checked the dip stick and found it was 2 quarts low. Today, August 27, 2026, I had the oil changed and the technician Found the truck was very low on oil.  Is there a Recall for this? What is my recourse for this issue? Do I call the dealer where I bought it or any chevy dealer?   Robert Strickland 292 Owego Road Candor, NY 13743 352-502-6588 [email protected]
