2020 CHEVROLET SILVERADO 1500 Complaints

Randomly. The power steering has stopped working. There is a widely reported issue with the power steering in 2020 Silverados and this model now needs to be included

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while driving at approximately 75 MPH, the electronic stability control (ESC), traction control, and check engine warning lights illuminated. The contact stated that several safety features failed to operate. The contact stated that there was a popping sound coming from underneath the vehicle. The contact pulled over to the side of the road to turned off the vehicle and waited before restarting the vehicle; however, the failure persisted. The vehicle was taken to the dealer but was not diagnosed. The vehicle was not repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 65,000.

A few month ago this 2020 Silverado check engine came on in the middle of driving. It stopped shifting and almost caused an accident because it wouldn’t stop. I took it to the dealer and they found nothing wrong. Today, it is doing the same thing with faulty shifting, especially during first and second gears and when I initially accelerate. It is jumpy and worried and accident will happen if the car stops shifting like before. The check engine light is on again

My husband was driving our family truck onto the highway to merge into traffic, when he lost all engine power, several dash lights turned on, and a clanking noise started. This was an extremely dangerous situation because the truck stalled, while trying speed up into highway traffic. He swerved to avoid cars and pulled off to the right shoulder. This a major safety issue because if either of my teenage daughters had been driving the truck, they would likely not have been able to avoid an accident! Mechanics confirmed the truck had suffered a catastrophic engine failure while driving. The dealership confirmed a lifter failed causing the damage. They said the whole engine had to be replaced. GM offered to pay half of cost, proving they know this is an issue. The truck's not even 5 years old, so the fact that engine would just stop while driving, when we had kept up with regular maintenance, sounded bizarre to me. I researched online and learned of 2 class action lawsuits (CA & MI) claiming GM knows about this defect in their engine and continuing to sell trucks with the same safety issue. Not more than 2 weeks after our incident, hundreds of thousands of the 6.3L engines were recalled after a NHTSA investigatio. GM has issued several service bulletins internally on "failing lifters", but has not told the public of the safety hazard. The service bulletins acknowledge the issue, recommending GM mechanics use a lighter oil (SAE-0W20 instead of the customary SAE-0W40) or change the oil more frequently. (service update N212353840). But car owners don't know this! GM is putting lives at risk, as no one expects their engine to completely give out while on the highway. Thankfully, my husband has been driving for 35 years. Had it been a younger, more inexperienced driver, they would not have been able to recover from the engine failure, especially while merging into high speed traffic - causing a crash, injuries and possibly death. The public deserves to know.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated while driving 65 MPH, the front wheels seized, and the contact was forced to pull over to the side of the road to restart the vehicle. This failure reoccurred a second time and while pulling over the front wheels seized, and the brake pad and rotors were visibly red. No warning lights were illuminated. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was unknown.

Transmission shudders started around 65k miles. Shop said it was recommended to do a transmission flush. We did that. Now at 72000 miles the transmission is locking up. It has been inspected by a reputable auto shop and they stated it needs a new transmission. The engine light came on when this issue happened. I was in the middle of traffic at a stop and when I started going it stopped abruptly and threw me forward. It was so violent that I thought I was rear ended. It did it two more times.

My transmission keeps shuddering my whole vehicle after the new software was installed GM claims it’s fine and normal when in fact it’s going to cause an accident.

2020 Chevrolet Silverado with 72K miles has a bad Transmission Torque Converter. Warranty expired 2 months ago and will have to be replaced in the next 30 days. Had the truck checked out at a local transmission shop that said this is happening on every v6 Silverado that is being brought in.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while her husband was driving 55 MPH, there was an abnormal sound coming from the vehicle. The driver pulled over to the side of the road and inspected the vehicle. The contact stated that her husband observed that the driver’s side front wheel had detached. The vehicle was towed to the residence. The vehicle was then towed to a dealer where it was diagnosed and determined that the control arms, rack and pinion, and ball joints had separated and needed to be replaced. The vehicle was repaired. The manufacturer was not notified of the failure. The failure mileage was 88,907.

I’m reporting a safety concern involving a 2020 Chevrolet Silverado 1500 with the 3.0L Duramax diesel engine. The vehicle went into limp mode and died on the side of the road. AAA installed a new battery, which temporarily restored operation, though the “Service Charging System” warning remained. I drove it home, let it sit for several days, and then took it to a Chevrolet dealership. Although the warning light had cleared, I brought it in out of caution. The first dealer diagnosed a failed alternator and recommended replacement at a cost of $2,158.75. I was also told the vehicle was not included in any active recalls related to this issue. Believing the price was high and wanting a second opinion, I went to another Chevrolet dealer. They ran the same diagnostic and found no issue with the alternator or generator, charging only a diagnostic fee. They also said if the alternator had needed replacement, the cost would have been around $1,300. I mentioned to both dealers that I had seen similar alternator/charging system failures recalled on other 2020 Silverado models. Online forums and customer complaints suggest that many Silverado 1500 trucks with the 3.0L Duramax are experiencing similar problems, indicating a potentially broader issue. Given the inconsistency in diagnostics, the significant cost discrepancy, and the number of similar consumer reports, I believe this issue may be more widespread than current recalls reflect. I respectfully request that NHTSA investigate whether the existing recall should be expanded or if a new recall should be issued for 2020 Silverado 1500 models equipped with the 3.0L Duramax. This issue occurred shortly after a separate failure related to the NOx sensor, which I am submitting under a separate complaint.
