general problems of the 2021 Chevrolet Silverado 1500

On 2-23-2026, while traveling at highway speeds on the freeway, the front upper and lower a-arms (control arms) suffered a complete structural failure. This caused an immediate loss of steering control, forcing the vehicle off the road. By sheer luck and reactive maneuvering, I was able to avoid a multi-vehicle collision; however, the failure resulted in over $4,000 in mechanical and body damage.

Upper control arm ball joint separated from the control arm causing steering loss.

The car while I’m driving, when I start driving it has a kick could be transmission.

1st incident cracked frame/suspension support for front suspension, 4 months to fix, 2nd incident oil pump, lifter failure, replaced under warranty. 3rd failure engine sieze while driving at 55-60 mph. Warning light flashed loss of oil pressure shut down immediately, put it in neutral to coat to side of road but moment I shifted to n engine failed, had to tow home cuz dealer was a month out to look at it, had to send to a different dealership 60 miles away to get looked at, confirmed castrophic engine failure, gm dealer wanted me to pay to fix it. I have had 2 major engine issues, 1 major suspension frame issue.

The upper ball joint on the passengers side failed or separated. This caused the truck to lose brake pressure and put the occupants lives in danger. The vehicle is currently at a GMC dealership in killeen, TX being repaired. There were no warning signs or lamps.

I purchased a used 2021 Chevrolet silverado from a dealership 5 months ago. Almost immediately after purchasing the truck, I would hear and feel an intermittent pop that originated from near the floor of the front passenger side. The sound became more frequent and would happen mostly when making sharp turns but also when making softer turns. I took it to the dealership to investigate. They had it for a week and supposedly examined the entire vehicle. They were able to replicate the pop sound when driving it but were unable to diagnose the problem. They claimed that sometimes trucks just make noise and assured me that the vehicle was safe to drive. I asked how they knew it was safe if they didn't know what the problem was and how was I to know that whatever is causing the sound isn't causing internal damage. The service manager again assured me that the certified mechanics looked at every detail of the vehicle and found nothing to be concerned about and sent me on my way. After taking the truck home, I continued normal use of the truck, taking it on 3 long distance trips on the highway. The sound continued as it had before, occurring intermittently when turning. 2 days ago, I was backing out of my driveway. I heard a very loud pop and got out of the vehicle to find that the front passenger wheel had completely broken at the ball joint of the control arm and was lying nearly flat on the ground, held suspended by the brake line and cv boot and other attached components. The truck was towed to the dealership, where it currently is. The service manager told me that the mechanics did everything that they were supposed to have done and that unfortunately this is a mechanical part that can fail and that he has seen this issue in 7-8 other vehicles like mine. If this is a common problem, there should have been a red flag when presented with this issue. If this would have occurred on the highway at a high rate of speed, my family and I could have been killed.

I went to dealer for an oil change last week. They told me the left front shock had a minor leak and they would be ordering me a new one. After arriving home I noticed that the passenger side shock was also leaking. On 11/28/23 the truck went to the dealer to get both front shocks replaced. Upon arriving home after the new ones were installed I looked at the shocks and noticed the passenger side was leaking fluid to the point it was puddling in my driveway. The fluid was pissing out from inside the shock. I began taking photos and videos of such. My wife is 22 weeks pregnant and this was in needed stress for her. Not only did the brand new shock fail but put her and my future baby at risk.

Upper control arm ball joint failed causing me to lose stealing control, luckily I was only driving 10mph, if I had been on the interstate this could have been more serious possibly fatalities involved, I have read reports this is a common thing, my truck is a 2021 silverado, I never received a recall notice.

The contact owns a 2021 Chevrolet Silverado 1500. The contact stated while driving 70 mph, the vehicle started to pull to the left and the contact became aware that front driver’s side wheel had separated from the vehicle. There was no warning light illuminated. The contact was able to pull over to the side of the road safely. The vehicle was towed to the dealer. A police report was filed. The contact was unsure if the vehicle was diagnosed. The dealer stated that the front driver’s side ball joint was defective. The vehicle was not repaired. The manufacturer was not contacted. The failure mileage was 37,000.

So I have been having issues with my truck losing oil. My dealership told me that walmart made an issue with the oil filter causing it to leak oil out. After the dealership corrected the issue. I was on my way to the store this morning it was damp so I was having a lot of traction issues. Got to the gas station checked tires, no issue with them. Temperature is above freezing. Just thought maybe it’s in my head. Well I get about 2 miles from my house and low oil light comes on again. So this is an issue. It has happened 2 times to me. Had I not been cautious I could have slipped off the road or had a collision because the oil mixing with the water on the roadways. I will be reaching out to my dealership tomorrow to try and get them to correct this issue again. Seems there is a service bulletin on how to tighten the oil filter. Because of oil leaks.

Body control modules sas modules no communication service esc light and traction control lights coming on vehicle looses all steers ng when lights come on at any speeds it says service esc power steering loss drive with caution have had it into multiple shops and no diagnostic scanners can get into the 3 systems there 6050 miles on vehicle we haven’t gotten in a wreck yet but that is totally not out of the question it will happen and when it does its going to be devistating.

Engine valve lifter failure at 20,000 miles; engine hesitation and power loss. Error to parking brake and to electronic stability control. Chevrolet to replace damaged lifter but refused to replace both banks of defective lifters. As a result of dysfunction I was stranded 1200 miles from home and have been waiting 2 weeks for repair. Still 1200 miles from home with 2 kayaks, 2 bikes etc.

I lost control of the vehicle when the road became bumpy. The vehicle was bouncing up and down pitching from side to side. I was driving the posted speed limit. This happened on the day I bought the vehicle and I was on my way home from the dealership. At first I thought the vehicle was acting like that because it was new. Nope. It's real. The truck bounces and pitches hard every time I hit a bump in the road. I even drove back to the location where it happened on the first day that I bought it and sure enough the vehicle acted the same way. The entire truck shakes and bounces violantly when I go over bumps. I'm talking about every thing. The second thing is that when the vehicle warms up it starts humming like an electrical type of hum or noise. The humming is coming from the passenger side of the vehicle and I can hear even when I'm standing outside of the vehicle on the passenger side. The transmission slips when I slow down and speed up again. The vehicle that I am driving is dangerious and shouldn't be on the road. City street or highway doesn't matter in my case. The truck will violently shake at the posted speed limit.
