2020 CHEVROLET SILVERADO 1500 Complaints

My truck felt like running over rumble strips. At 17500 miles they replaced my torque converter under warranty. Now at 24690 miles they had to replace again, under warranty. With less than 25000 miles it is on it's 3rd torque converter. I fear that transmission is being damaged and feel Chevrolet needs to admit there is a problem. My current dealer calls it a lifetime warranty, with lots of strings, but Chevrolet should protect me.

Passenger door lock failed. Door will not lock with any door button, key fob, automatic lock function, or when vehicle shifts to drive. Door must be manually locked by pressing lock down and unlocked by pulling door handle risking safety of passenger. Issue has been reproduced, inspected, and confirmed by independent mechanic but no diagnostic has been ran yet. There were no warning lamps, messages, or symptoms present prior to failure.

My Silverado 1500 has developed torque converter shudder again over the course of the past few days. My current mileage is around 42,000. This is actually the second time this has happened on my specific vehicle and the current torque converter is actually the second, as I had my other one replaced after being confirmed by a dealer several months ago. I have only managed to drive around 10,000 miles between the replacement of the first part and the start of the second one failing. For information regarding the first failure please use reference ID 11458308. This has not yet been confirmed by a dealer, but I'm scheduled to get this serviced on Tuesday. I am certain that is what this is as this happened so recently. Primarily while driving at highways speeds between 1500 - 2000 RPM my Silverado will continuously surge forward every few seconds with a notable clunking in the rear. While this is happening I will watch my tachometer bounce up and down approximately 300 RPMs constantly, despite the fact cruise is set and this is on flat ground. The problem gets worse while driving uphill and increases the magnitude of the clunking/shaking. Under light throttle acceleration my truck will have a vibration coming from under the vehicle that feels exactly like driving over a rumble strip. This was the sensation that helped the dealer identify this as torque converter shudder the first time. No warning lights were present at time of incident.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that upon purchase of the vehicle, he noticed an orange-colored rust underneath the chassis of the vehicle. The salesman assured him that the rust would be cleaned off once the sale was finalized. Months later, the contact noticed the same orange colored rust had returned. Upon inspection of the vehicle, he discovered severe corrosion located in several spots on the subframe. The contact took the vehicle back to the dealer for the repair. The contact then received a call back from the dealer and was informed that no corrosion was found, the dealer linked the failure to structural rust. The contact disputed the diagnoses and the dealer agreed to have a further inspection performed on the vehicle. The manufacturer was not notified of the failure. The vehicle was not repaired and remained in the possession of the dealer. The failure mileage was approximately 65,000.

Popping and/or Clunking Type Noise Heard During Hard Turns at slow speeds and backing up. Seems to be a problem with the control arm

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that after being parked for several hours, the vehicle was started and operated in drive(D) and reverse(R) however, the vehicle failed to turn to the right or left. The contact stated that the steering wheel had seized. The contact was able to disconnect the battery then reconnect the battery once the torque rebooted. The failure occurred twice. The warning light displaying an open wrench stating ESC needed resetting was illuminated. The vehicle was taken to the dealer who was unable to duplicate the failure. The dealer stated that the failure might be caused by the sensor in the steering column, or the module. The vehicle had not been repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 13,500.

While driving, the service emission system light activated indicating the truck would be reduced to 65mph. This was due to a faulty EGR wiring harness that controlled the EGR sensor.

The Advanced Trailering system will fail to load, preventing the user from entering the correct vehicle being towed and the entire system screen is blank and won't load. This could be a huge safety concern if the driver cannot select the correct vehicle being towed since the Brake Gain is stored in the Advanced Trailering system and then the incorrect amount of braking force will be applied to the vehicle while it is being driven, which could cause insufficient or excessive braking forces applied to the towed vehicle. This could lead to rear end crashes or Jack-Knifed crashes. The problem is random but repeatable quite frequently and has been confirmed by the Dealer (refer to included GM Bulletin PIT5792 Published on 11/5/2020) GM has been aware of this problem for almost 2 years and has not provided a fix for it. I have had this vehicle in the dealer on at least 3 occasions to fix the problem There is no advanced warning, message or other symptom prior to this problem. The problem started within a month of purchasing the vehicle

My truck had been randomly misfiring but the dealership couldn’t resolve the issue because the check engine light would go away on the way there. They were able to pull codes showing a misfire taking place and told me to return if it continued. The truck started having misfire issues again periodically fir the next 2 weeks but once the check engine light stayed on I scheduled an appointment. On the way to the appointment to Hidiburg Chevrolet we were on the interstate the cruise control kicked off, the service parking brake indicator, misfire flashing of check engine light, an ESC warning, and the traction control light came on as the truck randomly pulled to the right real quick then it stopped. Once the indicators went off all warning indicators were off and cruise control would not work. The dealership pulled codes and saw every cylinder misfired and that the other issues that took place. They tested everything and could not find the source and said that they had to wait until the indicator stayed on so they could see the issue. I left with no resolution and concern that when the misfiring could damage parts and the computer. I also fear that the issue if someone isn’t aware of vehicles not fixed could lead to severe accidents and potential for death if not fixed.

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.
