2023 CHEVROLET SILVERADO 1500 Complaints

There is a noticeable clunking or knocking noise from the rear suspension, possibly the leaf springs

Engine oil cooler lines began leaking oil at 800 miles. Oil leak appears to be at engine connection for line. Took to dealer where vehicle was purchased. They added dye to engine oil and clean up evidence of leaks. Told me to drive for 300 miles and call if it leaked again. It leaked again and dealer is non responsive to request for repair. Will try another dealer. Leak is significant.

Windshield wipers have stopped/paused during operation on two occasions midway through clearing rain from the windshield while driving down the road during rain events. Each time this has happened, the wipers have paused for approximately 2 seconds and then continued working without adjusting the controls. The vehicle is available for inspection upon request. If the wipers had not started working again, I could have lost the ability to see while driving on the roadway. This could have put me and family at risk of crashing, as well as other motorists on the roadway. The problem has not been evaluated at the dealership yet. There has been no lights, lamps or warnings this was going to occur either time it has happened.

2023 Silverado 1500 3.0 Duramax. Transmission failure and engine overheating at 5k miles. I was towing a trailer when the 1st transmission failure occurred. The engine shut off, and said shift to N to start while coasting with loss of power braking. I was able to get started but transmission would slip when shifting above 1st gear. I had to tow to the nearest level point to safely park the vehicle, for fear of rolling backwards down 8% grade. At that point the computer was showing engine overheat loss of power warnings. GM roadside assistance towed to nearest dealer, refilled transmission with fluid, and put me back on the road for it to fail again in traffic (loss of power / unable to move). I have now been without vehicle going on 30 days and worry there is more wrong with the vehicle than just a blown transmission (latest GM diagnosis with no repair eta). For a few hours prior to failure I noticed what seemed like the transmission hunting for gears at lower speeds (0-25) with hesitation. Could have been slipping. And also noticed strange / louder than usual turbo noises. I worry the system is generating too much pressure or has mixed oil with coolant somewhere, based on finding atf, coolant, and engine oil near the overflow and all over the bottom of the vehicle. GM support has been atrocious and someone should step in.

The audio from the stereo will cut out for all services, FM, Sirius XM, Apple CarPlay , phone. It’s happened twice within two weeks. Once I reset the stereo in safe mode., it works again.

Vehicle sways/wobbles on grooved pavement. Magnified immensely when towing a trailer. Threatens to pull you into other driving lanes. Service technician and service manager at dealership state it is a known condition with the type of tires Chevrolet has put on the vehicle and that Chevrolet is refusing to do anything about it. Multiple dates and is repeatable.

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated that while the vehicle was parked, the rear passenger’s side window suddenly shattered. The vehicle was towed to the dealer, who had not yet determined the cause of the failure. The vehicle was not repaired. The manufacturer was notified of the failure but referred the contact to the NHTSA Hotline for assistance. The failure mileage was unknown.

The automatic emergency breaking never worked. I took it to the dealership and they told me the computer didn't show anything wrong. I could tell the safety features weren't behaving properly though. While I was driving the breaks completely failed. Luckily I controlled the vehicle to a stop. Every light on the dash was on. I turned the of and restarted it. When I did the break peddle pumped repeatedly on its own hard back at me and made an awful noise. The check engine light came on and stayed on. From that point I tried to get to a safe location to call a tow truck to take the truck back to the dealership. While I drove I managed to get some video of the detection system as I closed distance to the vehicle ahead it saying the gap was widening and the car right in front of me would disappear. Then as the vehicle would pull away, the sensors would say the gap was closing. My safety and others was absolutely put at risk. If anyone would have been ahead of me when the breaks failed it would have been a deadly colission. After I told the dealership there was an issue and they told me I was wrong, then this happened, they have confirmed there is a problem and have had the truck for over a week trying to repair it. It has not been inspected by the manufacturer, police, or insurance reps. There was no warning lamps prior to the failure. The only symptom was that the safety features that were stated to be on the vehicle never worked. The truck was specifically marked to have automatic breaking, safety assist, front pedestrian breaking, following distance indicator, and forward colission alert that never worked on a brand new vehicle that never worked from the day I purchased the vehicle. I did report it by calling and even bringing the truck in to be looked at and I was told there was "no issue" by the dealership. Then the break failure took place.

GM Infotainment system repeated intermittent malfunctions. Safety concern: Repeatedly (~20%) while driving, the audio from the car radio will spike to full volume for about 5 seconds, then the infotainment system will reboot. THIS IS VERY UNSAFE as it is startling to the driver, nearly resulting in multiple crashes. This is an issue reported by multiple owners, as evidenced by a simple Google search of '2023 silverado volume spike'. GM has refused to acknowledge this and has not issued a fix.

We purchased a 2023 Chevrolet Silverado High County on Thursday, August 10, 2023, at Reed Chevrolet in St. Joseph, MO. On August 19, 2023, the infotainment system failed on the vehicle. It was returned to the dealership for repair. In coordination with General Motors, the dealership could not fix the issue. They said a new infotainment system was required, but they did not have a strategy or solution to our problem. They indicated this was a supply issue, and they could not get an infotainment system as it was back-ordered. On September 11, 2023, the dealership had to trade us vehicles as they could not provide a time frame for repair. We had to give up the 3.0 straight 6 Duramax diesel we wanted and go with a gasoline version. In communication with GM, they were aware of this problem, based on the careful wording of their responses and the 2021-2023 model year Silverado pickups. I researched these model ears and found this was a common problem among many Silverado owners. GM is also well-known for this issue infotainment issue and has settled a previous class action lawsuit for different model years. GM needs to be held accountable for this issue. I look forward to your response. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
