The posted speed limit in ohio was 65 at the time! NO it doesn't state in the warranty that you have to obey the speed limit, that is what I was told at my dealer...Hence the point I was trying to make is that they will try anything from flat spots on tires from sitting on the lot to "excessive speed" to get out from having to try to solve the problem!
GM would never BS anyone! Is it possible you purchased a buyback? They will also tell you since you are driving like a maniac (72+ mph) that you are over posted speed limits and that could void any warranty...Go buy Michelins then go from there
I will say this...I really think GM has screwed the pooch this time around. I know all the brands have problems(foreign and domestic) And most TRY to make it right, But on this one GM has went out of there way to avoid this problem....lying to dealers and customers, and by forcing dealers to do the same! It seems they really stuck it to there Loyal customers this time. And I strongly believe that they wont be able to wait on the next generation to bail them out
Hang in there, GM has 4 yrs experience of giving the runaround on vibration! If you are lucky like some you will find out quite a few visits were never documented
Has anyone read the article in the Jan/Feb Truck Trend Magazine about the 2019 Silverado/Sierra?
Most of the issues that GM has claimed was "operating as designed" since 2014 has been addressed in the 2019 models....Imagine that!!! Even states that this design wont feel like you are driving a "wet noodle" down the road like the previous years!
The best one is where the guy talks about people being to "proud" to admit they made a mistake. Talked to a few service advisors they would say people would come in complaining about rattles in dash or air noises.... take them down the road and they would be shaking and vibrating and nothing was mentioned.
GM gave me a dealer credit for 1000.00 My came with general grabbers and went to Michelins. That was at 19,000 miles, I have 66,000 now ...tires look good but still has shake. I do believe that a lot of the problems come from the "Factory Trained Technicians" That have no clue how to use the road force machine properly.... Even though they will tell you " I HAVE BEEN BALANCING TIRES FOR 20 SOME YEARS!!!! "
