"the vehicle has developed a recurring ticking/knocking noise in the engine, worsening under acceleration, accompanied by excessive oil consumption. This is a repeat issue after a warranty repair on June 6, 2022, where all 8 lifters on the right bank were replaced due to afm/dfm lifter failure. I believe the current problem is caused by metal debris from the initial failure scoring cylinder walls, rings, and bearings, leading to lower-end damage. Gm denied coverage under special coverage adjustment n242498000 despite the prior repair and matching symptoms in bulletin pip5623. Johnson motor sales quoted $14,893. 89 for engine replacement. The noise and oil loss pose a safety risk of sudden engine failure or loss of power while driving, potentially causing a crash. ".

Vehicle was at a stoplight with the auto start button engaged on it. The vehicle completely stalled. All the power is drained from the car. Leaving me stranded in the highway. I got it towed and when replacing the battery still nothing will roll over or even turn on.

When driving normal speeds to work on a county road, engine light comes on, service light comes on. There was a tapping noise and reduced power. Luckily, there was a sports field parking lot that I could pull into to get out of traffic. We had the truck towed to our house through our roadside assistance program so that we could determine what to do. If we had not been able to pull off the road as quickly as we did, we probably would have been hit by the semi that was barreling behind us. The truck had reduced power.

While driving down the road the engine quit. There were no indicators of anything wrong. Check engine light was not on. It just quit while driving. I didn’t have any notice. I wasn’t even able to get it off of the road. When it did come to a stop. The engine would not restart. I was stranded and had to get a tow. I had it towed to my mechanic and upon inspection, he says it needs a new motor. My truck has ran fine with all the regular maintenance up to this point.

As I was driving the vehicle it seems to be hesitating or jerking and when I tried to start it,it would say put your foot on the brakes to start,but my foot was on the pedal and it was slow starting. Days later the engine light came on,took it to the dealership and they told me it was a problem with the brake system. I bought the vehicle brand new,only 41,000 miles,on it now,warranty went out in June of this year. I very rarely drives it and now they saying its a 4,000 job to get it fixed.

Dealer says my vehicle is not approved to even check the motor out. Build date 6/21 6. 2l motor under recall.

Engine just died going 55 mph on a paved road. Gm repair shop says engine needs to replaced. They originally told me my 6. 2l engine was a recall, but my VIN didn’t show on database. Seems gm’s scope was not wide enough on their recall. I feel I deserve a new engine.

While driving on a residential side street my 2020 Chevrolet Silverado 1500 (81,996 miles) suddenly lost power steering and braking with no waring. Several messages appeared in the dash and the check engine light illuminated. I was able get the vehicle safely to the shoulder and put in park without power steering or brakes. At this point the engine stalled and would not restart. The vehicle was towed to the nearest chevy dealer on 10/29/2025. The technician verified the loss of power steering, brakes, and several other codes and diagnosed the issue as corroded engine grounding straps per gm bulletin #23-na-201. The grounding straps were replaced and the codes cleared. The technician test drove the vehicle and verified normal operation after the repair. I was responsible for paying the full cost of these repairs as my vehicle was out of warranty. I feel incredibly fortunate that this happened on a residential side street with no traffic. Had this failure happened on the expressway while pulling my 4,000 lb trailer, this could have been a fatal accident if I suddenly lost power steering, brakes and had the engine stall like it did. I see multiple complaints for this issue on the NHTSA website and the gm TSB for this issue dates back to 2023. I am shocked that this is not a nationwide recall yet. It is a significant safety threat to the driver and others. I also know this is not an isolated incident, as my service advisor at the dealer suggested it was probably the grounding straps before the technician even inspected my vehicle. It was pretty clear from our conversation that I was not the first vehicle they had repaired with this issue.

The contact owns a 2021 Chevrolet Silverado 1500. The contact stated that while driving 30-40 mph, the check engine warning light and other unknown warning lights were illuminated, and the engine was running rough. The vehicle was taken to an independent mechanic, where the contact was informed that the vehicle could not be diagnosed due to a lack of equipment. The vehicle was then taken to gary sapp automotive, where it was diagnosed with engine failure. The mechanic determined that the engine needed to be taken apart for the repair or replacement. The vehicle was not repaired due to the cost. The contact related the failure to NHTSA campaign number: 25v274000 (engine and engine cooling). The manufacturer was notified of the failure and informed the contact that the vehicle was not covered under an extended warranty. The failure mileage was approximately 89,000.

While driving on 401 east the vehicle started to shake and the service esc error code came on. This vehicle has had all service completed at GMC and had no issues. Stopped at dealership and they ran diagnostic tests to report back the engine has failed and requires replacement. 6,2l l87 is all ready on recall replacement but this same engine is not covered even though same symptoms and diagnosis was determined by dealership.

6 weeks since purchase and only 2000 miles-engine suddenly made a horrible rattling noise and stalled. Towed to dealership and was told engine was dead and needed replacement.

Gm 6. 2 engine recently tested for the national recall regarding valve and lifter issues. Recall was cleared as ok, but they found burnt cylinders in multiple areas within the engines. Several issues are still occurring with this engine, and I think most are related to the recall effort. 1. Engine will use oil at an abnormal pace when towing anything heavy. Recently used an additional 2 quarts of oil when towing a trailer that weighed 10, 000 pounds over 1600 miles. 2. Recently engine seemed to lose compression at a stop light and turned off. This happened an additional 5 times until I could get the truck off the road and into a safe place. The engine would immediately start and then die within 5-10 seconds. Towed to a Chevrolet dealership and the service manager tried to move it into the bay for diagnostic testing. Started and stopped 4 additional times as they attempted to drive if 100 feet into the service bay. Towed to my hometown dealer that afternoon for diagnostics testing. The next morning when they started the truck it cranked fine and has been running since (7 days). No lights appeared on the dash during the breakdown or warnings appeared in their testing I have spoken to several other Chevrolet owners about the 6. 2 engine issues and what was occurring with my truck they also had seen an increase in oil usage when towing heavy. I believe that your investigation needs to delve further into not only issues with the lifter / rods but also into other mechanical concerns that are oil dependent and related such as burnt cylinders. This last issue occurred on October 27, 2025.

While driving and idling, my 2023 Chevrolet Silverado 1500 high country equipped with the 6. 2l v8 engine began experiencing a persistent audible ticking/clicking noise from the engine bay, rough idle during cold starts, and noticeable/abnormal engine vibration. Shortly after, the check engine light came on. When scanned, diagnostic codes p0304 (cylinder 4 misfire detected) and p050d (cold start rough idle) were retrieved. The vehicle was inspected by an authorized Chevrolet dealership, and the service advisor and technician confirmed hearing a consistent clicking noise and documented that they contacted gm's technical assistance center (tac case #80413912). The service order report states: "due to unknown noise cannot perform recall. Called tac 80413912 and was told need to figure out top end noise and misfire before proceeding with recall. If repairs are related to top end, will not be covered under recall. " the technician indicated this could be related to a camshaft and lifter issue, which matches the symptoms outlined in gm's active propulsion system recall for 6. 2l engines. Suggests gm aware & has not yet confirmed full recall coverage/repairs. This issue presents a significant safety risk because the engine could experience sudden power loss or failure while driving, potentially leading to loss of propulsion or control. These symptoms are identical to those described by gm in their recall documentation concerning valve lifter and camshaft failures. The issue has been reproduced and confirmed by the dealership, and all documentation, diagnostics reports, and service notes are available for inspection upon request. Warning/check-engine lights first appeared in October 2025, and the problem persists. Based on gm's recall acknowledgment of similar failures, I believe this defect should be fully covered under the existing recall, and I am requesting NHTSA's review to ensure manufacturer addresses this safety-related defect promptly and without cost to owners.

I’ve purchased my chevy silverado brand new and I’ve had to bring it to the dealership multiple times for code p1098 this will be the second time this has been repaired. Looking on line this is very common. This is the second time I have to leave my vehicle at the dealership and not I don’t have my vehicle.

At 62,000 miles this engine blew up after regular maintenance.

I purchased the vehicle on 8-23-25. On 10-23-25 while driving my daughter to school I received a message on the dashboard that said "reduced acceleration mode drive with care. " I immediately drove to the dealership. After a few hours I was told by the dealer that the diagnostic code of po6dd "engine oil pressure control solenoid valve stuck off" had been recorded and a full engine replacement will be required. The vehicle has 3307 miles on it and has been at the dealership since. Engines for this vehicle are on back order and there is no timeframe available on when a new engine will be available.

Driving at normal highway speeds, "service parking brake", "service engine", and "electronic stability control" lights illuminated on the dash with no prior warning. When attempting to accelerate, to maintain highway speed there was noticeable roughness to the engine along with a tapping sound. I slowed and made the trip back to my home under reduced power. The vehicle was towed to the dealer the following day per the dealer's service advisor instructions. Issue was diagnosed as a collapsed lifter, bent lifter rod and damaged cam lobe. Total repair cost exceeded $10,000. Internet search of this issue reports a number of drivers reporting similar issues with the Chevrolet 5. 3 liter engine. If this issue had occurred in a more congested traffic area it could have caused an accident when my engine power was suddenly reduced without warning.

While driving the engine shut off without any warning lights which could have caused a serious accident causing bodily harm or property damages as I was unaware of the issue and was going 50mph at the time - this occurred on 10/23 I noticed a ticking and brought the vehicle to the dealer for inspection on 10/20, at the time of this inspection the technician said that they could not replicate the sound and I explained that this was happening at 3000 rpm. The technician said that I would need to bring the vehicle back and they would need to start to take apart my engine piece by piece and I said the ticking is part of the known lifter problem and the technician shrugged his shoulders offering no other options. That same day I took my vehicle to another independent shop and he confirmed the ticking is a known issue that occurs prior to the lifter collapsing. After the vehicle shut itself off, and I was able to restart the vehicle, many warning lights appeared on my dash, there were none there before, one of the codes that was flashing was esc and the vehicle began to lurch and downshift. I called my mechanic who said the code was to do with the electronic stability control system but I should be okay to drive until I could get to him for him to look at the codes. On 10/24 I took the vehicle to the mechanic and another code was for cylinder 3 misfire which he stated could be the collapse of the lifter and the codes will not clear. The vehicle now downshifts without warning, there is an engine knocking that is occurring and the vehicle is not safe to drive as the engine may seize at any moment.

The contact owns a 2019 Chevrolet Silverado 1500. The contact stated that while driving and depressing the accelerator pedal, the vehicle failed to exceed 35 mph. The check engine, parking brake, and service engine warning lights were illuminated. A dealer was contacted. The vehicle was taken to the dealer where it was diagnosed and determined that the lifters and camshaft needed to be replaced. The vehicle was not repaired. The manufacturer was notified on the failure and informed the contact that the dealer would be contacted; however, the contact was later informed that there would be no assistance provided to repair the vehicle. The approximate failure mileage was 115,000.

Like many others, I have been dealing with many issues with this truck. I have had repeated cooling valve failures, resulting in decreased engine power and constant cooling fan running at high speeds. Additionally, cranking issues with starting the vehicle.

We have had four previously documented issues with the electrical, brake and engine in our truck. Today, we were advised by the dealer that the truck had been fixed, and a new ecm had been installed. They advised they drove the truck for 100 miles and there were no issues. We picked the truck up and on the way home, while on the highway, the truck went into low power mode, the brakes went out, the check engine light and slip light came on. The dash began flashing detection warning lights (see attached photos): brake system failure 62 mph top speed, service steering column lock, reduced acceleration drive with care, service esc, service traction control. We immediately turned around and went back to the dealership and showed them what was going on. They took photographs and had the technician come out to look at the vehicle. He looked at the lights and codes and admitted he does not know what is going on. The service manager said that the company representative was coming tomorrow (10/21/25) and that he was going to speak with him and recommend a buyback. We left the truck with the dealer and were given a loaner car. This is the 5th incident with the same issues.

Started with a clicking noise that mechanic thought it was the fuel pump but found out later it was the bearing is the rocker arms that failed and ruined the camshaft. Now it needs a new engine.

Megafuse on starter solenoid terminal of the buss bar has blown twice in a month, leaving a serious burn mark on buss bar where contact is made with fuse. Possible fire hazard inside engine bay on top of battery. This also keeps the vehicle from starting. 1 click, no start. Battery has full charge, jumping has no effect. Possible cause is ground wire short/fault between negative terminal and vehicle frame/body. No check engine light, no battery light, or any other indication of issue with starter or battery.

The engine began to make a knocking noise at ~62000 miles on the odometer. I assume it was bearing failure. Murrey Chevrolet GMC diagnosed the problem as catastrophic engine failure with the repair being a replacement of the engine. There were no warning lamps. This is a 2020 Chevrolet silverado high country with the 6. 2l engine.

After buying my truck from mcfarland chevorlet in maysville ky I then moved to cincinnati OH for work for work and is about a 1. 5 hour away, all maintenance on the vehicle was done by a ase certified shop and never went over the millage. I bought a extended warranty (200,000) as well but was voided as soon as I had a oil change done at valvoline. My truck is at 85,000 miles and chevy nor premier auto insurance refuse to work with me to fix my truck. Blown engine -- collapsed lifter on cylender 4 and was told it need a new crank shaft also ! a chevy dealer near me quoated me $9,600 to fix this. Have been trying to get ahold of the dealership I bought the truck from and they will not return my calls.

Driving down the road and the engine turns off with no warning lights, noise, or any indication of an issue. I was luckily able to use momentum and move to the side of the road. The chevy dealer has inspected the engine and concluded that the engine is blown.
