| Feb 2025 | POWER TRAIN,ENGINE,FUEL/PROPULSION SYSTEM | On January 17, 2025, I was approaching the entrance ramp unto Interstate 10, traveling along at approximately 40 miles an hour, when all of a sudden I noticed that my vehicle started decelerating as I was pressing on the accelerator, trying to merge onto oncoming traffic. The engine started shuttering and vibrating violently! I noticed all the warning lights, gauges and indicators had come on simultaneously! There was a loud clicking sound coming from the engine compartment and backfiring coming from the exhaust. I evaluate the situation at hand and conduct a risk assessment of trying to continue on with this problem but decided to move over to the median. I was almost run into from the rear due to lack of power in which I felt would have been the result of my truck just losing power without any warning. I drove my truck to a Chevrolet dealership after speaking with a Service Advisor, on January 20, 2025. The Truck was diagnosed as needing to replace Cam Rod and Lifters. | Crash: No Fire: No | Unknown |
| Feb 2025 | ENGINE | At roughly 146,590~ miles the truck began making a knocking noise while driving at any speed, complainant had the truck towed to independent shop and was evaluated. Was told by shop that the engine can shaft pitted and engine metal shards had exploded and shattered throughout the engine. Making the opportunity for engine stalling or risk of fire/ smoking while operating the vehicle extremely likely. Complainant was told there was no access to engine replacements or parts at this time and the wait time to receive one was 4-6 months. No warning lights ever went off. Engine was eventually replaced entirely when the part became available by an independent service dealer. | Crash: No Fire: No | Unknown |
| Feb 2025 | UNKNOWN OR OTHER,VISIBILITY/WIPER | Rear sliding window is leaking from unknown area. | Crash: No Fire: No | Unknown |
| Feb 2025 | ENGINE | In November 2023 my check engine light suddenly started flashing, my service parking brake light came on, traction control light came on and service ESC message was on the DIC. Then my truck started running really rough. At the time I was going roughly 10 mph. I took it to the dealership and they found a lifter had failed. My truck was at the dealership for a month. Fast forward to now, February 2025 and today I got the exact same lights appear on my cluster and same message. I was driving approximately 50 mph and my truck felt like there was a lack of power and there was hesitation in the engine. | Crash: No Fire: No | Unknown |

| Feb 2025 | POWER TRAIN | The contact owns a 2020 Chevrolet Silverado 1500. The contact stated while driving 80 MPH, the transmission unexpectedly downshifted. There was no warning light illuminated. The vehicle was towed to the dealer where it was diagnosed and determined that the transmission had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 120,000. | Crash: No Fire: No Towed | 120,000 |
| Feb 2025 | UNKNOWN OR OTHER,ENGINE | The engine blew a rod through the engine block and dealership replaced engine June 2023. January 2025 engine abruptly stopped while on the highway at 70 mph and now waiting on diagnostic test from dealership but after reading all the incidents regarding this engine I feel it’s another L87 engine failure from GM | Crash: No Fire: No | Unknown |
| Jan 2025 | SERVICE BRAKES | This morning it was 16 degrees F I drove about 6 city miles at about 35 mph. I was 1.5 miles from home when leaving a stop light the truck bogged down and was only going up to about 25 mph with the tach at 2000 rpm. It seemed at first that I was driving with the parking brake on but most V8's have enough power to override the parking brake. This acted as if I was pressing hard on the foot brake while driving and giving it a lot of gas. I probably would have had to floor it to go any faster. But was afraid of damaging something. Put on the flashers and drove about 15 mph with the tach at 1500-2000rpm. The dash displayed "Brake system failure 62 mph top speed", "Service ESC", "Parking brake failure" and "Service trailer brake system", The brake pedal was changing its height by itself. Pulled to side of road and pumped the brakes several times, shifted the transmission through park, neutral, reverse and drive and it seemed to operate normally. Pulled onto road and it was bogging down the same. Pulled to side of road again. Then started driving again with flashers on and the tranny shifted as normal, but the brake pedal went to the floor. Pumped the brake pedal and it still went to the floor. Drove slowly while checking the brake occasionally but still went to the floor during the 5 blocks to my driveway. The brake had no effect. My driveway slopes slightly upward so I stopped safely. All four wheel centers and brake rotors were too hot to touch after slowly driving the 1.5 miles this occurred over. About 15 minutes later I turned on the key and the dash displayed "Brake system failure 43 mph top speed", "Service ESC", and "Service trailer brake system". Fortunately there were no vehicles close in front of me when this started and many were behind me when driving with my flashers on due to quite a bit of traffic. This could have been a disaster had it occurred somewhere else. The local Chevrolet dealer that services it has not seen it yet. | Crash: No Fire: No | Unknown |
| Jan 2025 | ENGINE | significant loss of power due to engine failure related to DDI while driving. | Crash: No Fire: No | Unknown |
| Jan 2025 | POWER TRAIN | Transmission shudders and has a delay in shifting/starting movement of the vehicle. This problem was noticed at 98k miles about a thousand miles after I purchased the truck from a dealership. It has been inspected, and repairs scheduled, but the transmission is still on back order after 5 months of waiting. No part ETA is available from Chevrolet corporate. This issue is a safety concern due to the fact that the vehicle could hesitate to accelerate in the event of needing to take evasive maneuvers to avoid an accident/road hazard. | Crash: No Fire: No | Unknown |
| Jan 2025 | STEERING | We were driving on the highway when we attempted to make a turn the Steering wheel would not turn. We almost had an accident. I, [XXX], the Driver, had to swing out, and force the steering wheel to turn to get out of traffic. The service steering system with care light and the ESC Light came on. My truck is not that old and should not experiencing this type of problem. This was a very frightening experience that I don't want to go through this anymore. I call the dealership that I purchased the truck from and learned that other models had a recall on the same issue, but my 2020 had no recall on it. So therefore, they did not have to work it in to fix it. So, I'm reporting the issue so that no one else have to experience what I did. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6) | Crash: No Fire: No | Unknown |
| Jan 2025 | POWER TRAIN,ENGINE,FUEL/PROPULSION SYSTEM | Vehicle purchased December 2020 Flashing check engine light that stays on- light did not stay on long enough for dealer to see, said they couldn't find any issues. The first time we had it towed and when they looked at it the light was no longer on. They were able to tell us what was going on with the vehicle when the light came on but said there were no problems. Flashing check engine light that turns off- "no light = no problem" dealer says. Eventually they printed pages showing engine misfires which we were initially told was no big deal. Later I was told I should get spark plugs changed, which I did. So far, flashing light has not reoccurred. Burns 3 or more quarts of oil between oil changes which I was assured by more than one rep that that was normal (on numerous occasions). Air conditioning quit working. Heater not working well and not at all on idle. The only setting I can really use to defrost and keep my feet warm is the "floor only" option. Mixed doesn't work, defrost only will freeze feet. Gas smell while vehicle at idle. Initially noticed when using auto start but have since noticed it does it with regular start as well. All issues have been brought to dealership, I will have to contact them for all the exact dates. | Crash: No Fire: No | Unknown |

| Jan 2025 | ELECTRICAL SYSTEM,SERVICE BRAKES,ENGINE | Vehicle has been in and out of service for the past 5 months with multiple alerts including "Brake system failure 43mph top speed," "service esc," "service brake assist." On major interstate car would not accelerate past 43mph putting myself, infant, toddler, and wife in danger. Multiple attempts have been made to repair the vehicle and nothing has been successful. Lifters, CAM, torque converter, EBCM, master cylinder, calipers, and the list goes on. When this happens the brake is extremely hard to press making it difficult to stop the vehicle. Issue has been reproduced by dealer and attempts have been made under warranty to repair. Car only has 36k miles on it and the issue began prior to that. GM ongoing solution is to bleed the brakes, which clearly has not resolved the issue. Still hear ticking and noises from engine. Something needs to be done to remedy this issue. This is a safety hazard for myself, my family, and everyone driving around me. | Crash: No Fire: No | Unknown |
| Jan 2025 | POWER TRAIN | 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. | Crash: No Fire: No | 60,000 |
| Jan 2025 | SERVICE BRAKES | 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. | Crash: No Fire: No | Unknown |
| Jan 2025 | POWER TRAIN,ENGINE | 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. | Crash: No Fire: No | Unknown |
| Jan 2025 | ENGINE | 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. | Crash: No Fire: No | Unknown |
| Jan 2025 | STEERING,SERVICE BRAKES,ENGINE | 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. | Crash: No Fire: No | Unknown |
| Jan 2025 | STEERING,SUSPENSION | Upper control arm ball joint separated. | Crash: No Fire: No | Unknown |
| Jan 2025 | ENGINE | 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 | Crash: No Fire: No | Unknown |
