When the truck was less than 2years and less than 20,000 miles old it developed a clunking noise in the rear suspension. Sounds like 2 heavy pieces of metal softly being knocked together. The dealership inspected it and replaced both rear shocks. The noise was still there. The dealership replaced the left leaf spring assembly. This temporarily eliminated the noise. The noise came back at just under 3 years and 30,000 miles. The dealership inspected, but couldn't find the source of the problem. The noise has only worsened since then, and at a recent visit to the dealership, they could clearly hear the problem. I was told that it is the result of worn cushions between the leaf springs. I'm concerned that the truck may be unsafe. I've been contacted by GM, and at this time they are looking into how to fix it, and who should be responsible for the repair. I can't imagine that mine is the only 2020 Silverado with this problem, and think there must be other reports of a similar nature.

vehicle has approximately 45k miles, We were 2.5 hours away from home on a paved highway driving 55mph and the front passenger side ball joint failed and upper control arm separated also Instantly no brakes causing an accident. This is very dangerous and is going to kill people, we are lucky we didn't roll. I'm now afraid this will happen to the other side" chevy will not take the responsibility to fix it, our extended warranty only covered the upper control arm and not any of the other parts that had damage due to the ball joint. it was a 2.5 hour tow as well. Also the tow truck driver said within a week this was the 4th Chevy truck with the same issue 2 of them Rolled. Side note, As I looked into this I haver found other of this same model vehicle to have the same problem, one that it happened at around 40k miles he fixed it then it happened again on the other side at around 50k miles on the same vehicle. There needs to be a recall, Chevy has other models that have had this recall but no recall for my vehicle" links to related proof there is a big problem [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I'm not sure what to call most of this but my truck has been vibrating when getting up to about 50 mph. When putting in gear it shows you put it in the gear wanted put doesn't register sometimes and perks you and clicks. The entire front end grinds, pops and clicks when turning forward or backwards. When doing the steering wheel will get stuck and want turn for a split second in turn causing steering To be misaligned causing you to basically steer the wheel in an unnatural position until you stop put it in park then proceed to drive again. I have had these issues since we bought the vehicle brand new. We have to get an alignment and balance rotation like every 6 months for it to only help for a about a month to not be as bad.

I was driving the vehicle but it sounded like it was popping when I would turn and when I shifted gears. As a result, my brakes were not working and I almost hit another vehicle. I took it to the dealership where they claimed they fixed the issue. When I picked it up this past Saturday, within a block of the dealership, the truck began shaking and a rattling noise could be heard. I had to take the truck back to the dealership. The truck is at the dealership where it is supposed to be inspected again and hopefully properly fixed.

Today while driving, the upper ball joint separated from the control arm, causing the truck to pull hard to the right. I was able to keep from wrecking the truck. While doing research it seems that this is a common occurrence with the Silverado Trail Boss and the Sierra AT4. I read a safety recall report on these vehicles, 21V-718, after reading this, it's exactly what happened with my truck. Ball joints is rusting and corroded. Vehicle is able to be inspected upon request. If I had been on the freeway traveling, it would have caused a severe single or multiple car accident as I lost control to steer. No symptoms leading up to the situation.

While driving down the interstate hi-way, I heard a pop and my truck started to swerve into the adjoining lane. I turned the steering wheel in the opposite direction and the truck started making a rubbing sound and very hard to steer. I finally got it to the side of the hi-way and seen my passenger side front wheel leaning in. The upper balljoint/control arm broke. Luckily no-one was in the lane next to me or it would have caused a serious crash.

Both front upper control arms are corroded.Vehicle is 2 years old and has 10375 miles.Dealer stated there is no outstanding recall or a TSB associated with this issue.This is a Trail Boss model with a lift kit from the GM.There is another recall that was issued for 19-21 models with lift kits with the same issue but apparently this model is not matching that yet the problem is very obvious.Please also note that the vehicle was also rustproofed immediately following the purchase.

It seems the top suspension arm on my front passenger side broke.

- Cambridge, ID, USA

At 11,000 miles my car began to wobble dangerously. I took it to the dealership and they informed me that two Pins were missing from the alignment cams. They blamed Goodyear for not doing a good alignment at 3,000 miles. Goodyear says they see a lot of these issues in their shop and believes GM needs to recall and fix this issue on all of its models. The repair cost me $459.69. GM said this was not covered under warranty, since someone else did the alignment. This doesn't see fair and I think the government needs to look into this.
