2020 CHEVROLET SILVERADO 1500 Complaints

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while driving at an undisclosed speed, the vehicle briefly hesitated and experienced hard shifting before returning to normal functionality. The vehicle had returned to normal functionality, but the failure became a regular occurrence. No warning lights were illuminated. The vehicle was taken to the dealer, who was unable to duplicate the failure. The vehicle was not repaired. After investigating the failure, the contact related the failure to NHTSA Campaign Number: 24V797000 (Power Train); but the VIN was not included. The manufacturer was not notified of the failure. The failure mileage was 60,000.

Upon entering a roadway from a parking lot I noticed my vehicle struggling to gain speed. I lifted my foot from the gas pedal and the truck rapidly reduced speed, dropping from 25 mph to less than 5mph in a couple of seconds. I then reapplied the gas pedal to attemp to avoid the vehicle approaching from the rear. The truck struggled again to gain speed. I went about 150 yards toward an intersection. I applied the brake and pushed it to the floor as the truck barely slowed to a stop. Had there been any vehicle stopped in front of me I would have hit it and pushed it into the intersection. The dashboard lit up with warning lights and rotating messages such as, Brake system failure 62 mph top speed, Service trailer break.when the traffic light turned green I drove it across the intersection into a parking lot, going about 5 mph for 50 yards. Putting my foot back on the brake as hard as I could. It finally came to a stop about twenty feet farther than it should have. I had it towed to a Chevrolet dealership. They did a diagnostic test and checked all braking components. They found a service bulletin for recalibration of brake system control module. They preformed the calibration and cleared the codes. After reading the many reports of this happening on the NHTSA site and the absolute possibility of injuries and deaths, I find it hard to believe that with knowing this problem exists and it’s disastrous potential, that there has not been a recall after 5 years of complaints.

Vehicle would not start, had it towed to a shop and they said the engine locked up. After tearing motor down the main bearing was scored and there were metal scratches.

Truck has been burning oil since it was purchased new in 2020. The truck has needed 6 quarts added between every oil change. It has been to the dealer and they insist nothing is wrong. GM customer service has been no help. Motor has a ticking noise. Finally 2 weeks ago check engine lights came on and loud noises came from motor. Brought it into the dealership and they said full lifter failure and engine scoring and has been like this for awhile now. This is something I brought up to them AND GM support over the last 4 years of owning the vehicle and they always told me there was nothing wrong with it. Private extended warranty is going to cover a new engine, but is on national backorder due to all the issues with the 6.2L engine and others having issues GM won’t acknowledge.

While driving home truck began to misfire and drop in RPM’s. Service ESC and Service Parking Brake popped up on my notification system. My Engine light was blinking and my Traction light was on. While i was turning into my street to get home, my engine shut off. The steering wheel and brakes became hard as the motor wasn't powering them. I was able to turn it on and get it into my drive way. Afterwards when trying to turn it on, it would turn on and shut off immediately. Chevy replaces a fuel pump module for a second time(recall), added a new starter and battery. After Three months they then told me I need a new engine because it has locked itself up. I purchased the vehicle with 32,000 miles and It currently has 49,000 miles. Chevrolet are not going to warranty me a new engine because i do my own oil changes (which were 2). Had this happened on the highway or in traffic, i would've been at a high risk of causing an accident considering power steering and brake system was not working properly.

I was driving on a wet Road with more than an inch of water on the road and all of a sudden my engine blew up I took it to the Chevrolet dealer and they told me that water got in the engine and it was my fault I feel that the engine failed and should not have

While driving down road at around 60mph 6.2L engine started to make loud knocking noise and shaking violently while loosing all power. Truck had 79,797 miles on it at the time with all oil changes and service done at GM dealership. After having GM dealership diagnose truck, it was determined to have a spun rod bearing, causing multiple other engine components to fail. Truck was not under factory warranty and was quoted $12,200 to replace. There were no warning lights or any known issues until this incident.

Had the top of the motor rebuilt twice, first the left side, then the right side. Then GM replaced the motor out of warranty. A year and a half later the rear main seal blew and the seal was all mushroomed and out of shape.

Purchased not thinking there would be issues as truck was clean and well kept. Month and a half later torque converter went bad. Had it replaced under warranty, however, I have more symptoms from when it originally started. 6 speed transmission.

While changing a blown fuse for the instrument cluster, my truck unexpectedly caught fire, endangering my safety and causing significant damage to the vehicle. The fire started behind the passengers side fuse box within the wiring harness (GM# 84717166). The dealership determined that the failure was due to wire harness chafing on the thread side of a tie bar bolt. Due to General Motors not responding to their request for repair information via the TAC, they concluded that the bolt needed to be shorten in order to reduce the chafing. There were no warning signs or indications that this was going to or could occur. The burnt harness is available for inspection but the vehicle has been traded in due to no longer trusting how it was manufactured.
