This data is from the NHTSA — the US gov't agency tasked with vehicle safety. Complaints are spread across multiple & redundant categories, & are not organized by problem.
So how do you find out what problems are occurring? For this NHTSA complaint data, the only way is to read through the comments below. Any duplicates or errors? It's not us.
The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while driving at an undisclosed speed, the vehicle experienced reduced engine power. The reduced engine power warning message was displayed. The vehicle was towed to the dealer where it was diagnosed that the rear main seal needed to be replaced. The dealer replaced the rear main seal; however, the failure recurred. The vehicle was taken back to the dealer, and the dealer replaced the rear main seal a second time; however, the failure recurred with engine oil leaking onto the ground. The manufacturer was made aware of the failure and a case was opened. The failure mileage was approximately 11,340.
I was driving down I27 10 miles south of Lubbock when my 2020 Silverado 1500 3.0 Diesel engine stopped accelerating. I was going 75 miles per hour and the truck just stopped causing trauma for me and my family we were lucky enough to get to the side of the road. I ended up calling gm roadside assistance and they sent a tow truck to pick us and the truck up. The truck wouldn't engage into drive nor reverse. Once towed to the dealership, Gene Messer Chevrolet, in Lubbock, Texas, a service tech mentioned that a ton of the lifters bending push rods are going out on the late 2019, 2020 model silverado due to cheaper lifters added to the vehicles due to Covid shortage supplies. In essence, they wanted to get these models out with no regard to safety of the consumer. I'm not pleased with the craftsmanship GM has lined out on these trucks, this could've ended way worst. They jeopardized my families safety for profits. Right now the truck is still awaiting diagnostics still won't drive nor reverse per dealer service tech. It's just a terrible situation, the truck is new only has 25,500 miles on it, this needs to be recalled.
Upon starting the vehicle for the second time one day, when placing the automatic transmission into 'D' - Drive, it began to roll backwards as if it was in Neutral on a slight decline and the brakes had to be applied to avoid rolling downhill backwards. After attempting to place it back into 'P' - Park and back into 'D' - Drive and attempting to try 'R' Reverse to try to get it to move forward properly, it would not go forward. After several tries and restarting the vehicle completely, it finally attempted to move forward but would only do so at a reduced speed and would not respond to the accelerator pedal beyond a certain amount. After trying again, it appeared to move forward a bit better, but then upon stopping at a stoplight and attempting to pull out for a left turn onto the road, the speed again was reduced and I had to immediately place it into 'R' - Reverse to avoid an accident due to oncoming traffic. Finally I was able to get it to move forward a bit better and was heading directly for the dealership but since the power just was not getting to the wheels (transmission?) I pulled over and shut off the truck for a few minutes. Upon starting the truck again, it seemed to move forward better after that but had the 'check engine light' illuminated. The truck is at the dealership now, they have had it nearly a week and said they will not begin to look at it for another week at least since they only have 2 technicians who can look at it.
Vehicle has approximately 15789 miles. Loud taking sound coming from engine began November 2, 2021 as I was on Highway. Dealer advises all 8 lifters and cam need replacement. My investigation reveals that this is a persistent problem with this type of vehicle and many reports have been made about this same issue throughout the USA. My service advisor advised me that they have already repaired several of the same vehicles for the same problem. Engine is defective and requesting a recall to release entire engine now that this engine will need major overhaul.
Service ESC and Parking Brake error. Drove to work with no issues. Started up to drive home and I kept hearing a "Ping" noise like hail hitting my roof. Then I thought my transmission was going out while driving. It is almost like it is firing out of order. Dealership ordered multiple parts: Misfire in cylinder 4 plus issue with the heads and push rod. GM decided that the issue it to be repaired rather than a new engine be put in.
The contact owns a 2020 Chevrolet Silverado 1500. The contact stated while driving 10 mph, the vehicle drove through a puddle of water, shuddered and jerked then loss motive power. The contact was not able to restart the vehicle. The contact had the vehicle towed to a local dealer who inspected the vehicle and diagnosed the failure as water entering the engine, and that the engine needed to be replaced. The vehicle was not yet repaired. The manufacturer was notified of the failure. The failure mileage was 21,400.
Service ESC and Service Parking Brake error. This was followed by loud pinging noises from the engine. Sounds like a misfire and knocking heads or valves.
Driving 50mph and the truck starts bucking, backfiring, and missing. Code appeared on the dash stating service ESC. Lack of Power steering and braking I parked the truck.
The engine light has come on 3 times with a truck with only 9000 miles on it I took it to the dealership who gave me a code of P12A6 they told me Chevrolet is aware of this problem but has not come up with solution yet or even wrote a program to reflash the computer. Now I have a paper weight in my driveway and being that I live in a dual town trying to find a dealership that will fix it and provide rental car or truck. This defect can be multiple reasons with the engine harness wires chaffing or torque converter or transmission plus the whole electrical system not cranking over the truck from what I was told last time. Now I'm waiting till 730 to call a dealership see if they have a roll truck to pick it up and get it to a dealership where they can try to fix this problem.
Battery keeps discharging. Making sure no lights left on in vehicle. Totally drained battery in just 3-4 days without cranking or moving. After recharge cranked normally
One of the coolant hoses rubs up against the crankshaft causing hose to bust and leak reduced engine power light comes on and check engine light Chevy had to use a different hoes to not rub against the crankshaft
This truck is 2 months old and only has 2300 miles on it. On Sunday 12/27, the truck would not start. All dash panel and light indicator warnings came on including 4 wheel drive assist failure, brake system failure, tps failure, check engine, battery error, etc. After jump starting the battery, the truck turned on but the check engine light stayed on all day. On Monday 12/28, the truck did not start again however, this time, no indicator lights, dash panel or anything came on and I was also unable to even lock the truck. It was towed to the dealership and after 2 days they still have not found the problem with the truck although they have indicated there is a clear problem. The truck is still currently at the dealership.
When attempting to start from a stop at an intersection when the auto start/stop function has stopped the engine, the vehicle will frequently hesitate to start, then once started exhibits unusual engine/transmission behavior. This truck is now on its fifth check-engine light service for identical failures of the auto start/stop function. The GM onstar diagnostics reports indicate 2 failure modes, one with the engine/transmission and the other with the lithium-ion battery. I have several concerns. 1, I may be stranded at an intersection with a vehicle that will not restart and/or has stalled in the intersection and 2, the lithium-ion battery will fail catastrophically leading to a vehicle fire.
Repetitive faults of the auto start/stop system. I have notifications on three separate occasions while driving the vehicle from the onstart diagnostics service of two identical faults. One, a defect with the engine & transmission system and one a defect with the lithium-ion battery. To date there has not been an effective repair. The latest attempt, replacing the lithium-ion battery, somehow has forced the system to no longer function under any condition. Driving conditions varied each time.
Whille sitting at a red light, the automatic engine stop feature activated and stopped the engine. When I released the brake and stepped on the gas peddle the engine did not restart. The vehicle had to be towed in for repair. The dealer made repairs in a somewhat timely fashion except that the part had to be ordered from the factory as none were available. Would have thought a starter designed to start and stop numerous times a day would have lasted just a while longer?
I have a 2020 Silverado 1500 lt trail boss with just over 5000 miles on it with one previous recall which was completed. On this occasion I was traveling on the highway at roughly 65mph when alert sounds came on followed by a message on the cluster saying to shift the vehicle to neutral and push start button. I did that and there was no response. I was in the fast lane and did not have enough speed to get to shoulder so I pulled to center turn lane of highway to stop. I attempted to start the vehicle several times over 5-10 minutes with no response. Cluster gauges would cycle like when vehicle is started, but it did not engage the starter. I also tried to remote start from key fob with same response. There was traffic traveling at high speed in opposing direction on either side so it was unsafe to inspect the vehicle. I used onstar to get roadside assistance and about 15 min later police showed up to provide assistance. Onstar said it would be close to an hour for a tow, but police got me one about 15 minutes later. Luckily Texas cops are pretty cool so we just hung out until tow truck arrived.
Hollow valve stem failure. Metal shards got into the oil & seized up the motor. Was driving 35mph at night on a busy 2 lane city street, no shoulder. Less than 1,200 miles on the engine
The truck is new with 700 miles. September 26th 2020 I came to a stop at a light.as I took off the truck started to jerk and the check engine light came on. I immediately drove it home. As I was driving home while in motion the truck would jerk when it was changing gears. I received a text from GM that said to have the engine or transmission serviced within 7 days. I did not drive it until I was able to take it to Chevy. September 28th 2020 on the way there the vehicle did the same thing. On September 30th 2020 the Chevy technician said the truck was ready he said the problem was a transmission control module that was not placed correctly. I picked the truck up October 1st 2020 and drove it straight home just fine. October 2nd in the morning driving to work the truck started to jerk again and the check engine light came on and I received another text from GM saying to have the engine or transmission serviced within 7 days. On the way to Chevy I had to stop at a light when the light changed green the truck did not want to take off and started to roll back and I almost hit a vehicle. I put the truck in park turned it off restarted it then safely drove it to Chevy. Today is October 4th and I haven't heard anything from Chevy I did not believe that a transmission control module would be placed incorrectly from the factory I believe this truck has some kind of defect and is unsafe to drive until Chevy figures out the problem.
