I was traveling on a 55mph road. My chevy silverado started to shake and lose propulsion. I pulled off on the side of the road. In idle it shook. The dealership was one mile to my south. I turned on the hazard lights and went to the dealership. I could only get the vehicle to 45mph as in shook very bad the whole way. It felt as if the engine was going to explode the whole way there. The vehicle was taken to the dealership where it has been initially diagnosed as a bad lifter.

I am submitting this complaint regarding a 2021 Chevrolet Silverado 1500 trail boss 4wd with the [6. 2l v8 (l87)], VIN [xxx], 101,000 miles. The truck was assembled in mexico in xxx, about six weeks before xxx, just outside the build range of gm recall 25v-274 (n252494000, engine failure). On 10/2/2026, [xxx], [xxx] a certified gm dealership, diagnosed crankshaft and lifter failure, matching the recall condition. Codes: p0300, p050d, p0016. The truck was shaking violently, the esc and emergency braking system failed, reducing engine power. Gm's part 573 filing attributes the defect to out-of-specification crankshafts and identifies a mexico-based crankshaft supplier. I ask gm to confirm my engine's build date and crankshaft source. A six-week gap in build date should not exclude a truck with the same failure. Engine failure can cause sudden loss of power while driving, a safety risk. The dealer quoted repairs of up to $10,292. 00. I request: that gm cover the repair in full as a goodwill adjustment. That gm and NHTSA review expanding the recall population to trucks built near my date. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Chafed or broken wiring harness (very common) — this is the most frequent cause on newer gm vehicles. The factory wiring harness to the mass airflow (maf) sensor is too short or secured with an overly tight zip tie. Engine movement causes the lin bus wire to chafe and break internally near the connector.

The contact owns a 2021 Chevrolet Silverado 1500. The contact stated that while driving approximately 35 to 40 mph, the vehicle stalled and failed to restart. The contact retrieved dtc: p228c and p030 after scanning the vehicle. The vehicle was towed to a service center, where the contact was provided dtc: p228c, p0340, and p0c6. The contact was informed that the timing chain and guide had failed and that the engine needed to be replaced. The vehicle was not repaired. The failure mileage was approximately 172,000.

I have received a voluntary recall notice on my 2023 Chevrolet silverado. The recall states that the vehicle may have a condition which can cause the fuel pump power control module to fail. If this happens fuel flow to the engine could be interrupted causing the motor to shut off. Would this be considered a safety concern if the engine shuts down on th highway?.

I was sent a notice of a recall regarding a fuel pump, power control module that needs to be taken care of, but it is not being accepted under my VIN number. I believe that there is this issue with my vehicle or something similar because every day I start the vehicle up for the first time and drive it. It is jerking me and does not have proper fuel or proper pressure to move the vehicle without jerking me. After 10 to 15 minutes it cleans up and drives better but then again we’ll redo it if I sit still for multiple hours and restart the vehicle again late in the afternoon it will do it all over.

Vehicle engine failed with approximately 48,000 miles. Prior to failure, engine shut off while traveling 55mph on a public highway causing operator to have to pull over to restart engine. Vehicle inspected by gm dealer who advised metal in engine oil, requiring engine replacement.

Driving on the interstate and the truck had a horrible vibration. It smoothed out and it did it again. I got off at the next exit and the engine was making a horrible knocking noise. I had it towed to my chevy dealer for inspection. They drained the oil and found excessive metal in the oil. They decided that the engine needs to be replaced. The truck only has 4524 miles on it and it was purchased in June of 2026.

Driving home south on [xxx] from new brunswick. The motor started acting weird. It gave me a low power message and then shut off and I coasted to the shoulder. After finally getting it, restarted the engine started and make noise from the bottom end I had went to chevy again and I asked him to do a pico test and they refused. They said my truck is too old. Remind you. I only have a little over 100,000 miles on this motor that’s been replaced from Chevrolet back in 2011. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

My vehicle was serviced for the chevy l87 recall a couple of thousand miles ago. It currently has 13343 miles on it and I was driving down the road and then all of a sudden the engine just stopped and my vehicle lost power leaving me stranded on a state route xxx in [xxx], which is a dangerous route with nowhere to pull off. This issue has been going on for years now and chevy needs to make this right. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The contact owns a 2019 Chevrolet Silverado 1500. The contact stated that while hauling a camper and driving approximately 60 mph, the vehicle lost automotive power while the accelerator pedal was depressed. The vehicle was towed to a local independent mechanic, where it was diagnosed with a rod bearing failure due to a possible collapse lifter. The local dealer was contacted. Upon further investigation, the contact associated the failure with gm service bulletins: 19-na-218 and pip5776c with contributing factors to the failure. The manufacturer was made aware of the failure. The failure mileage was approximately 90,000.

While driving at about 20mph we hear a grinding noise and the truck throws itself into nuetral and then shut off. The truck seems to be on like when started with the key fob, on but not fully started. A warning message comes on the dash stating "conditions not safe to drive". The truck would not go back into gear, even after pressing the start button and truck regaining power. Pressed on the brakes to stop, put in park and then back into drive. Message warning went off and truck drove as normal again. This has happened twice since purchasing the vehicle in may 2026.

While driving in a parking lot. Barely applying throttle to move straight forward not turning or driving on a rough road the truck completely shut off all screens went blank and I wasn't able to accelerate. I was able to restart the truck, shift into drive and continue but took a few seconds to realize the issue and properly restart the engine. Thankfully this occurred while in a parking lot without anyone behind me but this is a real concern for me now driving on streets/highways with other vehicles around. This truck was purchased brand new has never been off road and has just over 3,100 miles. There were no warning lights before or after this incident.

Intermittent issues seemingly related to power or ground problems. At idle, battery voltage drops down from 14-15v to <= 12v (as indicated on the voltmeter on the dash) while turning the steering wheel. "service stabilitrack" message shows up on the screen, and the steering becomes very difficult. Last night this issue happened and the truck completely lost power including interior lights, headlights, radio, accessory power, and the engine even turned completely off. This happened in the middle of the street as I came to a stop in front of my house and was going to reverse into my driveway. Cycling the key was enough to restart the truck and the power came back on. When this first happened to me almost two years ago, I brought the truck in for transmission concerns (resulting in a transmission replacement) to my local dealer, and I explained what had happened and they could not reproduce the concern and said everything checked out fine. I've had strange electrical problems pop up every now and then including this stabilitrack warning message and a trailer brake warning when I am not even hauling a trailer, but this is a major safety concern. My wife and daughter were in the truck with me when it happened, and if the power ever shut off like this on the freeway, major road, or even off-roading, it would be disasterous.

The water pump went bad at 31,000 miles. If I continued driving and the pulley fell off the engine would overheat. I took it to the dealer and they confirmed the pump failure and want me to pay over $1,400 for repair that should be covered under warranty. There was no warning lamps lit, the pump just started making a grinding sound.

No warning lamps or chimes. Truck shut down as I was pulling into my garage. Shifted to neutral on its own and a message on the dash said to put it in park and restart the engine. This event happened on 9/15/26. The truck has 1400 miles on the odometer.

The contact owns a 2026 Chevrolet Silverado 1500. The contact stated that while driving 70 mph, the vehicle burst into flames. When the police and emergency services arrived, the vehicle was fully engulfed in flames. The contact stated that an oil change was performed prior to the failure. The fire department extinguished the fire. A police report was filed. The contact associated the failure with gm service update: n262568830 (potential oil filter leak). The customer service assistance at the manufacturer was notified of the failure and opened a case. The failure mileage was approximately 11,000.

I have noticed a ticking noise that is coming from the engine, driver side, the tick after the recall was preformed, 5-23-2025. The tick has grown in loudness from that date. Took the truck to the dealership and they did a check but was unable to locate anything, no parts were removed and no witness marks on any of the engine areas example oil pan and so on. I was told that they would charge me if the truck was brought back for the same issue per gm not the dealership. They have been doing my oil changes at a 3,000 mile interval. The tick has gotten progressively louder, and I am nervous about driving my truck but I can't not work.

Got my truck back yesterday from in shop for 2 weeks from being repaired. Got to red light just stopped my engine shuts off. Dash shows engine/transmission problems. Exact same thing happened two weeks ago. Had to get towed into dealer again this am.

Engine noise, unable to pass or fail pico test due to to much noise in truck. Engine failure.

I tried to get a tune up and found out that the engine need $5000 worth of engine repairs. I have changed the oil and filter every three thousand miles. Those engine are defective and the repair shops are full of the same type of repairs on that type of engine. My engine is a 5. 3-liter v8, the engine started to make ticking noises out of nowhere and then it started missing badly. The repair shop informed me it would take 3 weeks before I could get it repaired at the cost of $5000. I did research on the 5. 3 liter engine and found out that gm produced a engine that will cost us owners a lot of our heard money for a defect they created, this is so wrong because I am a senior citizen. I paid over $50,000 for a limon that is just wrong.

V8component affected: electrical system / power train (transmission) / engine cooling & wiringdescription of the safety defect and incident:while operating the vehicle, severe electrical degradation occurred due to a catastrophic failure of the factory body-to-chassis grounding system. Upon professional inspection by a certified mechanic, it was discovered that the primary ground wires had suffered extreme thermal degradation, with the mechanic stating that the wiring components "almost melted in his hands" upon physical touch. Because the vehicle's manufacturing-defective ground strap severely corroded and failed, the high-amperage electrical current redirected itself along an unintended path of least resistance: directly through the transmission shifting cables and internal wiring harnesses. This extreme electrical bypass caused extensive thermal damage, melted critical electrical insulation, and permanently fried the transmission control module (tcm) and internal transmission components, causing total mechanical failure. Why this is a critical safety hazard:fire & thermal risk: the failure created an active thermal event under the hood. Electrical current reaching temperatures high enough to melt heavy-duty wiring harnesses poses an immediate vehicle fire risk while operating or parked. Sudden loss of propulsion: the electrical short directly compromises transmission communication, risking an uncommanded shift into neutral or total loss of motive power while driving at highway speeds, creating a severe crash hazard. Manufacturer action / request for investigation:general motors recently issued customer satisfaction program #n252515590 specifically to address this exact "body-to-chassis ground strap corrosion" defect on 2019–2024 silverados.

Loss of power , catastrophic engine failure.

I was driving down the highway doing 70mph when my check engine light started flashing. I had to pull over and turn off my truck and turn it back on in order for it to go away. I brought it to the dealership and they explained that I had a misfire on the entire driver side of the engine and I would need to replace it. I have kept up on all of my vehicle maintenance but it still requires a new engine, costing $11,000 if not covered under warranty. This is a known problem with the Chevrolet 6. 2l v8 engine and is now a class action lawsuit with the company.

The contact owns a 2021 Chevrolet Silverado 1500. The contact stated that while driving at an undisclosed speed, the vehicle was smoking. The contact stated that the engine was smoking heavily with a strong oil odor, before the vehicle shut off. The contact stated that the engine warning light was illuminated. The vehicle was restarted and driven to the dealer. The manufacturer was notified of the failure. The vehicle was taken to the dealer, and the technicians confirmed the engine failure. The contact was informed that the engine needed to be replaced. The vehicle was being repaired. The failure mileage was 78,000.

As noted in my last report that I sent to you now my truck needs an engine because of a road knock. This is the second engine. It was changed in 2011 and I’ve been complaining about this and I wanted chevy to do a pico test they refused to do it because they’re telling me it’s too old but the truck only 111842 miles on it as prior complaint coming back from cape may, the truck stalled I toasted to the side and it took a long time for it to start back up and when it did, it started knocking real loud now chevy refuses to do anything about this. Maybe I could get some response out of you. Thank you for your help.

Following recall review by the dealership, experienced sudden, catastrophic engine failure nearly stranding me on the road with my son. Awaiting final diagnostics from the dealership, but every indication, errors, and symptoms align with all the other complaints that I have reviewed on line for the make/model of my vehicle. Recall assessment and corrective actions ineffective resolving engine failure.

Have notice that the car jerks hard from time to time and when try to accelerate the car does a quick/short stop then accelerates hards very jerky. Also I smell coolant and my check engine light came on. .

My 2021 Chevrolet Silverado 1500 rst with the 6. 2l engine experienced an engine seizure. The engine was replaced by a Chevrolet dealership under a gm safety recall. Immediately after picking up the vehicle following the recall engine replacement, the truck stalled while still in the Chevrolet dealership parking lot. There was no warning before this first stall. We continued our trip because we did not realize at the time that the stall could indicate a problem following the engine replacement. During the drive from [xxx] to [xxx], the problem continued. In [xxx], the check engine light illuminated and the truck began malfunctioning. The vehicle subsequently stalled again. The problem continued after returning to [xxx]. A Chevrolet dealership in [xxx] inspected the vehicle and reproduced/confirmed a problem involving the camshaft position sensor wiring/connector. The dealership demonstrated the problem by manipulating the connector/wiring and recorded a video of the diagnostic procedure. The vehicle is currently at the Chevrolet dealership and is available for inspection. The affected component should also be available for inspection because it has not yet been repaired. The [xxx] dealership has characterized the wiring/connector condition as normal wear. However, the first stall occurred immediately after the gm recall engine replacement, while the vehicle was still on the repairing Chevrolet dealership's property. Unexpected engine stalling creates a serious safety risk because the vehicle can lose propulsion without warning while driving, including at highway speeds or in traffic. I am concerned that the camshaft position circuit/wiring/connector problem may be associated with the recall engine replacement procedure or replacement engine. I am requesting that NHTSA investigate whether other vehicles receiving this gm 6. 2l engine recall remedy have experienced similar camshaft position circuit failures or unexpected stalling after engine repair.

I am filing this complaint regarding a serious engine lifter/active fuel management (afm) failure in my 2015 Chevrolet Silverado 1500. The vehicle experienced a lifter failure that caused significant engine problems and created a potential safety concern while driving back from shopping: loss of power, engine misfire, severe shaking, ticking, check-engine light, stalling, inability to maintain speed, etc. The vehicle had approximately 200k miles at the time of the failure. The vehicle was inspected by a local mechanic, which diagnosed the problem as collapsed/failed lifter. The repair required/will cost approx. 3k or more estimated my concern is that this does not appear to be an isolated failure. Other owners of 2015 Chevrolet Silverado 1500 trucks equipped with gm's active fuel management system have reported lifter failures, including failures resulting in engine damage and sudden loss of engine power or propulsion. A sudden lifter or related engine failure can create a significant safety hazard, particularly when it occurs at highway speeds, while merging into traffic, crossing an intersection, or in another situation where the driver depends upon the engine to maintain acceleration and vehicle speed. I am reporting this in hopes that gm can be held accountable as they knew about these defective lifters but did nothing but hide it.

The engine started making a ticking noise and getting a little louder while driving to dealer where I had purchased the veichle and had it serviced as called for . They had me leave to check it out , they called me 2 hrs later and said it would need a new engine and it had a spun crankshaft bearing and would be 3 weeks to get the new engine . They said my warranty would cover the billing . I’m presently waiting to hear from them . They told me that the new engine would have a warranty but minus the 31615 miles that my odometer reads now ?.
