Mccredy motors replaced the engine due to a recallin 6/2025. Husband was driving from our home [xxx] to town and we had made it to [xxx] . Husband stated there was no warning, no engine light, no oil lights, no indication of over heating. Just a loud clunking all of a sudden, nocking, grinding and crackling. Husband immediately pulled over left the truck over night at the greene town barn and we called in the morning to have the truck towed back to mccredy motors on the morning of 4/4/26. Reading up on this I have found the even after the recall and a new engine customers are still having catastrophic engine failures. This is absolutely what I feel we are currently experiencing. Mccredy motors will diagnose on Monday when the certified chevy dealership opens. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The 6. 2l v8 motor is known to have faulty internals. I was driving down the highway and the motor shut off. The vehicle needs a new motor now. Gm has offered an oil viscosity change to 0w-40. That was done 20k miles ago. This vehicle now needs a new motor.

Failed/collapsed lifters associated with known active fuel management (afm) issues. These issues are documented in technical service bulletins and I believe there are special campaigns for 2014-2018 l83 engine, but my VIN does not have a special campaign attached to it for some reason. I believe there are also class action lawsuits associated with these known issues, but a recall has not been issued.

Summary of incident: on March 28, 2026, while traveling at 70 mph on the florida turnpike, the vehicle suffered an instantaneous loss of motive power. The engine died abruptly with no warning. Upon reaching the shoulder, the electronic transmission locked, refusing to shift into neutral or park. The engine cranks but will not start. 1. Component failure & availability: the exact component is currently unknown, but the failure involves the powertrain, fuel system, and electronic transmission control. The vehicle is currently at an authorized dealership and is available for inspection by the manufacturer or NHTSA upon request. 2. Safety risk: the sudden loss of power at highway speeds created an immediate risk of a rear-end collision. Because the electronic transmission locked and would not allow the vehicle to be shifted into neutral, it became a fixed object on a high-speed shoulder. It could not be pushed to a safer location, increasing the risk of a secondary accident. 3. Problem reproduction: the vehicle was towed directly to an authorized Chevrolet dealership. As of this filing, the dealership is in possession of the vehicle, but the failure has not yet been reproduced or confirmed by a technician as they are awaiting formal diagnostic commencement. 4. Inspections: the vehicle was inspected by a roadside towing professional for transport. It is currently at the manufacturer’s authorized service center awaiting a formal diagnostic inspection. No police or insurance inspections have occurred. 5. Warning symptoms: there were no warning lamps, "check engine" lights, or messages prior to the failure. No symptoms like rough idling or unusual noises occurred. The vehicle performed normally until the moment of total power loss.

While driving down the freeway at 80 mph, in my 2025 chevy truck with 6000 mikes , the truck suddenly locked up, almost throwing myself and my daughter into the dash, thank goodness the semi truck behind us was paying attention of we would be dead! I was able to steer it to the shoulder of the road where I unhooked the battery hoping to reset the system to no avail. Waited on the side of the road till the tow truck got there. Towed the truck to my local chevy dealer where they confirmed the engine was blown, I want chevy to do a buyback on the truck as I have zero confidence in the truck, do not feel safe in it anymore, my daughter swore to never set foot in it again after such a dramatic event. I now have to wait a month for the dealer to install a new motor, at which time they will not give me a loaner truck, very disappointing. 1-total engine failure. 2-mine, my daughter, the semi truck driver, and many other surrounding drivers safety and lives were put at risk. 3- yes the dealer has confirmed it was a totally engine loss. 4-no one else has inspected the vehicle 5- no light, sensors or warnings just a loud bang then our lives flashing before our eyes.

Truck has less than 1800 miles. Was at a stop light and the vehicle started shaking and making metal tin rattling sounds. Stopped for gas, started the vehicle all noises went away. Got onto the freeway and about 1 mile down the road the truck lost power at 70 mph. I slowed down and the vehicle continued to lose power. I put my flashers on and started to pull over and the truck died, all dash lights went black and the truck was off. I rolled to a stop and parked the truck. Called a tow truck. The vehicle wouldn’t start. It turned over at first and then nothing. I was not able to shift the vehicle into neutral. The tow truck asked me to assist while we dragged the entire truck into the flat bed trailer. Dealer called late after noon the next day. Saying the motor was seized and had to be replaced entirely. The service technician said this has been happening to the 2021-2024 6. 2l engines as well and they’ve seen plenty of them. They recalled those a used a band aid fix of replacing the oil with heavier weight and a new drain plug. He said it’s not working and all those trucks are having the same issues. He said, this was not his first 2026 motor seized in a 6. 2l. He’s had another one recently low mileage that seized also. I asked for a different motor. I was told not to worry we will give you a 3 year/100,000 mile warranty. The truck was $100,000! and now they only want to warranty it for the same 3 years, just higher mileage… the motor is on back order and no telling when I’ll get my truck back. This is my 3rd silverado and my 2017 is still going strong with 100,000 miles on it. They have a serious consumer issue on their hands and should be buying these trucks back as we will not be able to rely on the new motors. Some people have had 3 and 4 motors replaced for the 2021-2024, 6. 2l engines.

I'm reporting a 5mpg fuel economy reduction immediately following the 6. 2l l87 engine recall (NHTSA #24v795000). I use 93 octane and monitor my fuel mileage consistently. I bragged about my fuel economy in my 6. 2l until after the recall was applied. This is going to cause a financial hardship as I'm on fixed income after servicing 29 years in the army and 100% disabled. There is no other reason my mpg should have changed as my driving habits have not.

I am reporting another engine failure on the 6. 2l l87. This engine passed the initial recall testing and the oil was changed to 0w40 on September 30, 2025. However, my engine in my 2023 lt trail boss started knocking on Friday, March 20, 2026 (at 22,500 miles) after I picked up my children from school. Thankfully it started as I pulled into my driveway with them so they weren’t in any danger. No loss of power on the truck or warning lights visible. However, it was loud enough and odd enough for my [xxx] olds to even notice the sound in the cab. It was dropped off at the dealership on that Saturday morning and the gm dealership was finally able to look at it on Wednesday, March 25th and confirmed what was expected. The advisor stated the engine will need to be replaced due to the engine heading towards bearing/crankshaft failure. I am still currently without my truck as of today (April 4th) with no repair date in sight. I will say that the dealership service advisor has been very good about communicating about its status. However, he stated that he has had no luck finding an new engine and is unable to give a timetable in getting one. He did offer to start a po for a rental car through enterprise. He stated they are not giving loaners, but could get a rental car. He also stated that it would not be a truck due to gm only giving $50 per day towards a rental. So here I sit currently without my truck. I see multiple reports about the engines being on back order and even the replacement engines are failing within the fist 500 miles. Some reports indicating they are on the third or fourth engine. Something needs to done about getting these trucks bought back by gm. They have clearly failed with this engine and are replacing the failed engines with the same thing! it is a well documented manufacturing flaw and design! I am thankful it occurred near my home. I would not have been happy with a catastrophic failure on a highway with my [xxx] old children in the truck!! information redacted pursuant to the freedom of inf.

I had a 2020 chevy trail boss and the piston rod broke. Chevy stated I needed a new motor. At the time it was 5 weeks or more to get fixed. I traded it in for the same style truck because I was on vacation and needed to get home. (2025 with the l87 6. 2 motor). My new truck has 21000 miles on it and I have been noticing a rougher idle, oil use between oil changes, and metal debrie in the oil and oil filter. I’m afraid this new truck will blow up too. I lost money on the 2020 truck and now it looks like the same is happening to my new one.

While driving on the freeway without warning, my engine stopped working. My vehicle was towed to the chevy dealership where they confirmed that I was the latest victim of the ongoing engine failure problem with the 6. 2 l engine. There was no warning, no sign that I had a problem. My engine just simply stopped working on a busy freeway. I was barely able to make it to the shoulder where I had merging traffic coming on the freeway behind me. I’m deeply concerned that chevy will replace it with the same faulty engine and I will be put in the same danger situation again in the future.

While driving in early morning while still dark outside, loud noise occurred with decreased acceleration on interstate. This placed my life and the lives of others at risk due to not being able to accelerate out of traffic coming behind me. Vehicle taken to chevy dealership who advised lifter had broke and damaged camshaft. This occurred out of nowhere without any warning or lights on dash.

The vehicle is currently exhibiting a loud, rhythmic metallic ticking/tapping noise from the top of the engine. This is a known precursor to a sudden, catastrophic loss of motive power as documented in gm service bulletins pip5847a and pip6101. The cause is attributed to manufacturing debris within the hydraulic valve lash adjusters, which prevents proper lubrication and causes valvetrain desynchronization. This defect leads to severe engine misfires (dtc p0300), "reduced engine power" mode, and potential engine seizure. ?1. Component/system: the 2. 7l l3b engine valvetrain / hydraulic lash adjusters. The vehicle is available for inspection. ?2. Safety risk: the audible ticking indicates imminent mechanical failure. This defect causes sudden and unexpected loss of motive power at highway speeds. Driving in this condition puts me at extreme risk of being stranded in active traffic or losing power while merging/passing, creating an immediate risk of high-speed rear-end collisions. Gm is aware of this debris-related defect via tsbs but has not issued a safety recall to prevent the resulting power loss. ?3. Dealer confirmation: yes, confirmed by Chevrolet dealer on 3/18/26. The dealer knows about this particular issue, and decided not to act. ?4. Inspection history: inspected by authorized Chevrolet service technician. ?5. Warning symptoms: loud metallic ticking/clacking that increases with engine rpm. This is a known precursor to a sudden, catastrophic loss of motive power as documented in gm service bulletins pip5847a and pip6101.

Driving down road truck quit, no warning. Left granddaughter stranded on road. Towed to gm dealership. Diagnosis was complete engine failure. Vehicle is there now waiting for decision to repair.

My coolant control valve has failed, the dealership is saying the radiator is now leaking at a weld. They said this is a know issue, but are refusing to repair it. It is caused by the know failing ccv, causing the radiator to overheat.

What is happening with my vehicle is a major safety concern in my opinion for myself and for my family. I purchased the vehicle on February 18,2026 from ryan Ford in sealy,TX with approx 32,800 miles. The first incident was on March 16 with 33,718 miles, my daughter and I went to leave the lowe’s parking lot and my vehicle would not go in reverse. It however would go in drive, so after being pushed back out of the parking spot we left for our home. (this part of not going in reverse I do have on video) once on the feeder road and up to approx 45mph my vehicle went completely out of gear and had to coast to a stop on the side the road. Turned vehicle off and on and it went back in gear, after making it home I made and appointment with the dealership and dropped it off that day. I was informed no codes came up and the dealership could not get the issue to duplicate so I received my vehicle back. The second incident was on March 21 trying to leave the convenient store, I put my vehicle in reverse and pressed on the gas to go backward and nothing happened. Then I pressed on the gas again and it threw my vehicle in reverse and jolted my truck back several feet before I could press on the brake. Luckily no one or no object was behind me. The third incident was on April 3rd trying to leave walmart. My truck would not go in reverse again. I pressed the gas pedal several times and out of nowhere again it threw itself in reverse and jolted my truck back again. (I also have this on video as well).

I was driving in the rain 3 nights ago when my chevy silverado unexpectedly started shaking very bad , jerking while trying to brake, surging forward and total loss of acceleration. My dash lights were blinking and I was scared ,I had no idea what was going on. Since our family are loyal jba customers( we own 2 silverados) and payed for the extended warranty and certified warranty I drove straight there and explained what happened. I was scared and crying, just diagnosed with vulva cancer stage lllc. Well the truck has been in the shop at jba diagnosed with bad cam shift rod and lifts. They want $10,300. 00 for repair. Even though we've been with them so long and had every maintenance done through them they weren't helpful in helping. Can someone help me? I need to be able to get to john's hopkins for my cancer treatments. I've looked up this issue and it looks very common. Please, help me. Jba had me sign a document so the dates can be verified.

I’d like to report a serious, ongoing safety concern with my 2019 Chevrolet silverado (5. 3 v8 53,028 mi) since Dec 2025. Over the last 4 months, I have experienced at least 20 engine failures/loss of power, with no engine light illuminated after restarting truck. These failures result in a complete loss of power, including steering and braking, posing a significant risk of a crash. Chevy said it would be hard to diagnose with no engine warning light on. Feb 24th, engine failure, warning light stayed on and towed truck to chevy. Truck on standby, repaired Mar 10th, replacing 2 oxygen sensors per diagnostics. Picked it up on March 11th, but engine shutdown again the same day and 4 additional failures while driving in my neighborhood, making the truck undrivable. I reached out to chevy service supervisor, juliana, but have received no response for the last 10 days. I urge NHTSA to investigate this defect as it poses a severe safety risk. Thank you for your urgent attention.

I was driving at approximately 75 to 80mph on the highway when my engine shutoff and the vehicle died while driving it. I was able to coast to the side of the road but had to cross two lanes to the left to do so while weaving in traffic to get to the shoulder of the road. There was no warning of any kind that would have made me aware of an issue prior to this happening. I was unable to get the vehicle started again and had to have it towed to my local dealership hendricks Chevrolet in columbia, SC. That occured on Saturday March 14th 2026, that Monday, I have had all regular and scheduled maintenance done to my vehicle either on time or prior to the recommended time including oil changes and the like. I went to the dealership and they told me that the engine had seized up and that this was a very well documented and common issue with the 6. 2l l87 v8 engine dating back to 2019 but that gm had only issued recalls on the 2021 - 2024 years to correct the issue. I asked the service manager at hendricks Chevrolet to file for a goodwill coverage request on my behalf to cover the repairs of the engine and he refused and stated that I had to do so through gm customer service line. I have done so since and my case number with gm is 92108267. My vehicle is currently at the dealership awaiting the go ahead from gm to replace the engine. I have an extended warranty on my vehicle that goes to 120,000 miles and the issue occured at 114,113 miles. This is a very well documented case where the engine connecting rod bearings fail due to oil starvation that leads to engine seizure.

Vehicle shakes severely, will not accelerate, check engine light on, and has gone into limp mode. Diagnostic codes p0304 (cylinder 4 misfire) and p2101 (electronic throttle actuator fault triggered by engine shaking and limp mode) were recorded. All external components including spark plugs, coils, and injector harnesses were inspected and ruled out as causes. Failure is confirmed mechanical and internal. This failure was diagnosed and documented in writing by an authorized Chevrolet dealership on March 12, 2026 (repair order xxx, service advisor [xxx] ). The dealer's written estimate states verbatim: "failed cylinder 4 exhaust roller follower failure causing exhaust camshaft failure and bent exhaust valves. Cylinder head replacement required to correct this concern. Direct cause of engine noise and misfire condition. " dealer repair quote: $10,371. 34. A second independent shop confirmed the same failure and cited active fuel management (afm) and direct fuel injection (dfi) as known contributing design factors in this engine's oil consumption and internal wear pattern. That shop quoted between $11,876. 88 and $14,897. 35. This is a known pattern in the l3b engine platform. Consumer reports has documented a 4% catastrophic failure rate in this engine. Multiple NHTSA complaints exist for this same failure across 2019-2022 model years. Gm has issued technical service bulletins but has not issued a recall. General motors was formally notified of this failure via certified mail and executive email on March 24, 2026. Vehicle is inoperable and poses a safety risk as the failure causes sudden loss of power and engine shaking w information redacted pursuant to the freedom of information act (foi.

The contact owns a 2021 Chevrolet Silverado 1500. The contact stated while driving at various speeds, the vehicle started shaking abnormally. The service electronic stability control (esc) warning light, parking brake warning light, a wrench warning symbol, and the check engine warning light were illuminated. The vehicle was not taken to the dealer to be diagnosed or repaired. The manufacturer was informed of the failure and confirmed that there was no recall associated with the VIN. The contact was referred to the NHTSA hotline to report the failure. The failure mileage was approximately 125,000.

Driving at highway speeds the message center prompted us to restart the truck and put itself into neutral. Upon attempting to do so, the message center read conditions not correct to shift. We were traveling in a single lane highway thankfully on a decent where we coasted into a parking lot. The truck list all power steering and brakes. We turned the truck off and attempted to restart. Lights were randomly flickering on and off, but the starter couldn’t turn the engine over. After 3 hours of waiting on Chevrolet roadside assistance we obtained our own tow service. The truck tires had seized up causing the driver to drag the truck into the flatbed. The emergency brake kept resetting itself. The following day 7/13 Chevrolet had the truck towed to the dealership. On Monday 7/16 we were informed the engine had catastrophic failure with less than 24k miles. This is the second major engine breakdown as the first was at 5k miles where one side of the engine had collapsed lifters. Engines are on back order but in reviewing other experiences the replacements experience the same issues. The truck is not a safe vehicle to drive.

Random catastrophic engine failure randomly made a clunk noise and oil pressure dropped to 0. Engine needs replaced.

The transmission died on my 2. 7l turbo max engine in my 2022 silverado. The "d" was flashing and giving no acceleration when pressing on the gas. The vehicle was also hard to shift. From my understanding the 2. 7l turbo max is the only engine in this time frame that hasn't been re-called due to transmission issues.

2023 1500 rst 6. 2. Recall was done and performed last year. Truck passed so they changed the oil and sent me on my way. I have had zero issues up until last week. My gut tells me the replacement is going to be the same engine with the same failing parts that I already have so expect I may have issues in the future even after the new engine. -on interstate going 55mph, went to accelerate to 70mph and throttle did nothing; no rpm,no down shift, no speed change. Just dead. Suddenly the truck shut off the engine and kicked my transmission into neutral. I tried to restart the truck hoping it would fire just long enough to get me to a safe zone with no luck as the starter would turn but nothing from the engine. Mind you this was rush hour in a construction zone with no shoulder available at the moment. Luckily I coasted, got to the slow lane and was able to veer off safely onto the side of an exit ramp. No notice, no way to safely limp my truck, just a complete shut down. How this isn’t a lawsuit or more people haven’t been seriously injured or worse is beyond me- a total shutdown while driving highway speeds and no way to overcome or at least limit the speed for a short period is unbelievable. Even though warranty is now through 2033/150k miles for the powertrain due to the recall, and I’ve also thought about adding 3-4 years extended for bumper to bumper with all the tech, I now have zero faith in my truck or my safety once I get it back. I’m sure the trade value will also be considerably low due to the 6. 2. I’ve owned chevys for 12 years and am either going back to the 5. 3 or switching brands altogether. Possibly a 5. 7 hemi without etorque.

Bought the 21' silverado about 18 months ago, recently the truck began to sound and drive terrible, it was found to be a bad high pressure fuel pump, bad lifter, and damaged camshaft. Dealership acknowledged that these are common issues w/ this model & year of vehicle and the parts are defective parts that they use in the manufacturing process of this model. They deemed it was out of warranty range as it's still under year 5 however I exceeded the powertrain warranty by 10,000 miles so they will not cover the issues and damage.
