STRUCTURE:FRAME AND MEMBERS
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.

TIRES:TREAD/BELT
The driver-side rear tire (P275/65R20) tread became separated while driving on I95 North with a fifthwheel. The tread became separated from the tire and caused sever damage to the trucks driver side rear wheel well and potential of losing control of the vehicle while towing a fifth wheel with my family of 5. The tire had to be replaced in another state so we could travel home and was not kept. There are pictures of the tire. There was no warning of this tire defect before it occurred.

SERVICE BRAKES, UNKNOWN OR OTHER
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

SERVICE BRAKES, FUEL/PROPULSION SYSTEM, POWER TRAIN
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.

ELECTRICAL SYSTEM, SERVICE BRAKES, STEERING
As I was backing out of a parking spot in a lot my vehicle lost it's power steering. I got an Service ESC error code, a wrench indicator, and a service power steering/drive with care warning. I also got a diagnostic alert from On Star. Diagnostic Alert: Service Antilock Breaking System in your 2020 Silveragod pithing the next 7 days. I was unable to move steering wheel, and could only pull my vehicle forward. So it was stuck sideways in the parking lot for about 20 minutes. My car did restart again and the code cleared. I was able to drive it to the dealer. They ran diagnostics but were unable to duplicate the concern. They did find a history of 1 fault where several modules (ECM, EBCM, TCM, TCCM) had lost communication with the power steering control module. They also looked at Data Com schematic doc 5257308 and found modules before connector X182 had lost communication. My safety was a risk in this situation because I was stuck sideways in a parking lot with very limited ability to move my vehicle for incoming or outgoing traffic. Had this happened while I was driving the vehicle in a roadway I believe it could have caused an accident. The dealership did find that a harness was making contact with the upper control arm bolt. They re-taped the harness and secured it away from the control arm bolt and bracket. A new bracket was ordered.

ENGINE
I am a volunteer firefighter. On Friday, June 24th 2022, I was responding to an emergency call around 1am. There was an active rainstorm and standing water on parts of the street. While driving through roughly 5-6" of water on the way to the fire station, my truck's engine suddenly shut off and I came to a stop. While stalled, I watched multiple cars travel through the same intersection with no issues. My fellow firefighters helped me get my truck to a nearby parking lot to sit and dry out. The following day my truck still would not start so I had it towed to the dealership where I leased the truck which was still under a full bumper-to-bumper warranty. After initial diagnostics, I was told there was water in my intake and I had to get my insurance company involved for the dealership to continue with the repairs. With no other choice, I opened up a claim and was given an estimate of over $9,500 for the repairs due to the engine being "Hydro-locked". I called GM and filed a complaint. They called the dealership and called me back stating the dealership told them I drove through a flooded road and damaged my engine. I did some brief research online and found several examples from multiple sources with the exact same issue. I feel that this is a design flaw and that this needs to be investigated further as I was stranded by myself, in a heavy rainstorm, in the middle of a roadway at 1am. There is no reason that a 2020 Chevy Trail Boss should not be able to travel through the amount of water that stalled my engine. There was nothing negligent about my actions and at no point was I worried about traveling through the water that I drove through. I feel like I am being treated unfairly in this situation and I would like someone to look through the databases to see how many similar consumer reports there have been regarding this design flaw. This is a major safety issue!

LANE DEPARTURE: BLIND SPOT DETECTION
The component that recently failed on my 2020 Chevy Silverado is the side detection/blind spot warning. It no longer works and upon startup of my vehicle the notification on my dash shows “side detection temporarily unavailable”. This problem started 3 weeks ago. After doing research online, it seems that there is a common issue in Chevrolet vehicles with water getting into the rear sensors in the bumper. There were also several new model Silverado’s with the same issue. As you can see, this is a safety issue as this feature all of a sudden stopped working on my truck so I no longer get warned if someone is in my blind pit while I am driving. I contacted my local Chevrolet dealership and they stated that because my vehicle is over 30,000 miles (36,000), I am no longer covered under warranty to have this issue repaired. My vehicle is scheduled to be looked at by the dealership on 6/27/22.

UNKNOWN OR OTHER
I have been researching rust on frame components and found there have been service bulletins issued (e.g. PI0564K) for this same issue. However, the latest service bulletin only covers up to model year 2019. Is there anything in progress to extend to model year 2020?
