  1. Engine, Forward collision avoidance, Apr 21, 2026

    right bank collapsed lifter. this is the 3rd time in 5 years this has happened same side same lifter. loss of power engine shakes the whole truck. Also electronic emergency brake won't release automatically and engages when driving. This has happened when I first bought the truck in Mar 2021, again in nov 2024 and currently at antelope valley Chevrolet on Mar 20 2026 for the same thing.

  2. Engine, Apr 18, 2026

    When taking off it will sometime have hard shifts, shuddering, and acceleration hesitation. While driving, it will do static jolts. Dealer couldn’t pin point problem and advised for a new transmission or we could drive it until it dies. Dealer didn’t recommend to change transmission oil in fear of creating more damage.

  3. Engine and engine cooling, Apr 17, 2026

    The contact owns a 2021 Chevrolet Silverado 1500. The contact stated that additional engine oil was needed a month or two after an oil change. The contact stated that one quart of oil was added every 1,500 miles driven. The vehicle was taken to a local dealer, and it was informed that it was normal operation for vehicles with the 6.2L engine. The vehicle was not repaired. The manufacturer was informed of the failure and opened a case for the contact and referred the contact to the NHTSA Hotline to report the failure. The contact researched online and related the failure to NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling); however, the VIN was not included in the recall. The failure mileage was approximately 22,000.

  4. Engine, Apr 16, 2026

    I am writing because I have a truck with the 6.2L L87 engine and it has been burning oil at every start up and acceleration from stop signs or stop lights, it blows out a blue cloud of smoke. I have asked Jeff Belzers in Lakeville , Mn to look and they did not as my vin did not show up in the recall. I took it to Maur Chevrolet in Inver grove heights, Mn and they told me that my miles were too high and they did not do an oil consumption test. I am burning 2 1/2-3 quarts of oil every 3,000 miles. I called the GM customer service line and they said there is nothing they can do except note it, so if I do get it repaired and pay for it, I could possibly get reimbursed in the future. If there is a known issue with this engine and there being 3 different engine builders, than why is it that my engine doesn't fall under that recall. It has all the symptoms of the engine failure that is specified in the recall? And it started about 6 months ago. Thank you Sincerely, [XXX] P.S. I have 136,000 miles and the special coverage warranty runs out at 10 years or 150,000 miles. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

  5. Engine, Apr 15, 2026

    The coolant control valve failed and the repair resulted in an engine oil leak which persisted for 8 weeks and still has not been repaired. The service manager at the dealership and General Motors Company are trying to figure out how to fix it but are not able to yet. They may have to replace the engine is one thing the service manager said to us this week.

  6. Engine, Apr 14, 2026

    Engine Temperature fluctuates. Check engine light comes on, prompt on dash will say engine is overheating. Engine fan stays on high. Code on scanner states Coolant Control Valve. GM has issued special coverage on this exact issue. However, they tell me my truck is not covered. I am very upset with GM as they are failing to address a known concern with my vehicle.

  7. Engine, Apr 12, 2026

    On January 2, 2026, I brought my vehicle in for service to replace the upper and lower ball joints, as well as the control arms. I retrieved the vehicle from the repair shop on [XXX] and departed the same day for travel to Mississippi. Later that evening, while traveling southbound on [XXX] near Columbia, Tennessee, I stopped at [XXX]. Upon re-entering the highway and accelerating to merge into traffic, the vehicle began shifting through gears abnormally. While in approximately 6th gear at around 2,900 RPM, a loud banging noise occurred, followed immediately by a significant loss of engine power. At the same time, the check engine light illuminated. Due to the sudden and unexpected loss of power while actively merging into highway traffic, I was nearly rear-ended by another vehicle. I was forced to take immediate evasive action and pull onto the shoulder to avoid a collision. This incident created a highly dangerous situation not only for myself but for surrounding motorists. This lifter failure occurred without warning and directly impacted my ability to safely operate the vehicle in a high-speed traffic environment. I believe this presents a significant safety concern that warrants investigation. There have been over 600,000 recalls for this and Chevrolet's solution was an entire engine replacement.

  8. Steering, Electrical system, Engine, Apr 9, 2026

    I am filing this safety complaint regarding a documented engine wire harness chafing defect in my 2021 Chevrolet Silverado 1500 with the 2.7L L3B Turbo engine. While driving, my truck experienced erratic acceleration, engine throttling to 3,000 RPM without returning to idle after releasing the accelerator, engine misfires, sudden loss of engine power, stalling, and multiple simultaneous warning lights. These conditions created immediate safety and collision risks on public roads. GM issued TSB 21-NA-149 in June 2021 and a second bulletin September 17, 2021, both before my November 2021 purchase, identifying wire harness chafing in the L3B engine caused by a manufacturing error. A wire harness clip was removed during production creating an uncontrolled harness branch that contacts sharp edges on the ECM/TCM bracket, upper control arm, and shock tower during normal engine vibration. This defect was built into the vehicle at the factory and was never disclosed to me at point of sale. The defect manifested after warranty expiration causing cascading failures; wire harness, catalytic converter, and transmission, all within five weeks. Vehicle has been inoperable since January 8, 2026. Defect confirmed by independent mechanic and by Ancira-Winton Chevrolet (authorized GM dealer) in their own repair documentation referencing GM Bulletin 21-NA-149. Dealer documented catalytic converter failure as consequential damage from wire harness repair. GM created Customer Satisfaction Program N192219370 for this exact defect. My VIN was excluded despite experiencing identical symptoms. No safety recall has been issued. Loss of throttle control and stalling at highway speeds represents an imminent collision risk. I request NHTSA investigate a formal safety recall for 2019-2023 Silverado 1500 and Sierra 1500 vehicles equipped with the L3B engine.

It was Sunday Chevrolet is closed so I got off the exit to go to auto zone in XXX. I stop at a red light my engine shuts off. I tried to turn it back on twice and it starts to smoke where the battery is. I have it towed to Chevrolet Fairfield. Where they figure out my ground wire came loose and shorted out. I paid for that to get fixed upon returning to get my vehicle on August 31, 2025 I drive not even 10 miles down the road and I hear a boom and then really loud clanking. I blew my engine. It was diagnosed with the same problems as other 6.2 gm motors. I have it towed back to Fairfield Chevrolet. It sat in Fairfield for a couple months due to me working out of town for work and the manager from Fairfield Chevrolet started giving me problems harassing me saying that if I didn’t get it off of his lot he was going to start charging me. So I had it towed from Chevrolet Fairfield to my house in [XXX] where it has sat since. I have been going back and forth with Chevy because I know of the recall however my vin is not in that recall yet it is the same problems as all the ones with the recall. I am really wanting to fix my vehicle as it has been almost 9 months. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

    My vehicle has been at the dealership since February 4 due to a transmission failure involving the valve body, which is currently on national back order along with the converter. These parts are required to complete the repair, and the vehicle is not drivable. This issue occurred after previous major repairs, including engine lifter replacement and a CV axle repair. It has now been 71 days without a repair. The dealer has confirmed the failures, but the manufacturer has not provided a repair timeline or a definitive solution. I have not received consistent updates since March 19, and the vehicle remains out of service with no estimated completion date..

    On February 12th, the check engine light came on in my 2021 Chevy Silverado 1500 with the L87 6.2 L engine. The following morning, I took it to the shop and had it checked. It was diagnosed with crank shaft bearing coming apart. I contacted the dealership and they told me that my VIN was not associated with the L87 recall, but that they would see if GM would be willing to help with the costst associated with replacing the engine. They agreed to pay for about 30% of the repair. I pointed out to them that my engine was manufactured in the Tonowanda, NY plant which is the site where many of the recalled engines were manufactured. They still refuse to cover the cost of the new engine. I feel that they should cover my costs since the engine was manufactured in the plant and broke down for the exact reason for the recall. My costs are over $10,000 due to their defective engine. Please add my VIN to the recall.

    I brought my vehicle to the dealership on March 7, 2026, to address the outstanding safety recall. However, I was informed that the recall repair cannot be completed until I first pay $1,100 to replace the idler pulley. Unfortunately, an unexpected $1,100 expense is not currently in my budget. It is quite concerning to continue driving a vehicle with a known risk of losing propulsion, as the increased risk of a crash is a significant safety worry for me. I would appreciate any assistance or alternative solutions you can provide to ensure this safety recall is resolved. Please find the message from the dealership: Additional Diagnostic recommendations: we are going to want to get the Idler pulley replaced 1st as it can cause unwanted noise and vibration during the testing with the Pico scope. after the repair take the vehicle on a good test drive get it good and warm Then retest the engine with the Pico scope and proceed with those test results. we still want to make sure it is tested correctly If the engine passes just note under Special Coverage N252494003 This special coverage covers if an engine failure occurs in the vehicle as a result of the condition described above for a period of 10 years or 150,000 miles (240,000 km), whichever occurs first, from the date the vehicle was originally placed in service, regardless of ownership."

    In 2024, the vehicle began experiencing severe jerking and drivability issues that appear to be transmission-related. We first took the vehicle to Terry Cullen Chevrolet in Southlake. The vehicle remained in the shop for months while still under warranty, yet the issue was never properly resolved. Attempts to communicate with management were largely unsuccessful, and we received little support in addressing the problem. Following guidance from Chevrolet corporate customer service, we then took the vehicle back to the original dealership, Nash Chevrolet in Lawrenceville, Georgia. Nash Chevrolet also held the truck for several months without resolving the issue. During this time, my husband who is self-employed in the home renovation industry—was left without adequate transportation. Because his work requires a truck, he was unable to complete scheduled projects, resulting in an estimated loss of $50,000–$60,000 in income. After the vehicle was returned to us, the same issue occurred again. When we attempted to contact Nash Chevrolet for assistance, our calls were no longer returned. We were forced to seek help elsewhere and brought the truck to a GMC/Buick dealership in Newnan, Georgia. The vehiche is unsafe to drive and after further research found this information and this is exactly the issue we have experience out of this truck making it unsafe to drive-8-Speed Transmission Issues (2015-2019): Litigation exists for 2015–2019 Silverados equipped with Hydra-Matic 8-speed transmissions, alleging rough shifting, hesitation, and vibration.

    Belt tensioner/idler pulley began chirping during warm up after starting engine. Noticed serpentine belt was beginning to fray on edges. Dealership confirmed the pulley failed prematurely and caused the serpentine belt to be damaged. Dealership replaced pulley and belt. It was just after warranty expired. The belt is supposed to be replaced at 100,000 miles as routine maintenance, but the failure of the pulley, which the dealer informed me was also premature, but common, was not covered under warranty. Power steering was lost one time in park and a message showed on the dash, but went away after restarting the vehicle.

    I bought this Truck in December 2023 from Honda of Ocala as a used vehicle it had 59,000 miles when I bought it. In October 24 it started smoking from the exhaust one morning as I was leaving work. I have always changed the oil on time and taken good care of the truck. I found out the lifters had failed and Honda of Ocala replaced all of my lifters on both sides around $4,000 in repairs the truck was at 73,000 miles at this time. A few months after getting it fixed the truck started smoking again and going into limp mode at 81,000 miles. I still owe $30,000 on this truck but can’t afford to keep fixing it and can’t afford to trade it in and go negative on it.
