1 Engine And Engine Cooling problem

Failure Date: 09/24/2026

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?.

2 Engine And Engine Cooling problem

Failure Date: 09/12/2026

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.

3 Engine And Engine Cooling problem

Failure Date: 08/26/2026

The engine in my 2023 silverado zr2 (6. 2l l87 v8) failed. It is available for inspection at rick hendrick Chevrolet ([xxx]). On xxx at about 67,000 miles, and the days leading up to it, the truck repeatedly struggled to start due to metal on metal contact, almost leaving me and my family stranded multiple times. Driving the vehicle produced a loud rattling noise at 2200 to 2700 rpm, and felt unsafe to drive. Especially with my family. The problem was reproduced and confirmed to be an engine failure by the rick hendrick chevy dealership a week after being dropped off with an appointment. I have been told the engine needs to be replaced under the special coverage program (n252494003). The l87 recall inspection and oil change was completed on xxx also by rick hendrick chevy. There were not warning lights or other symptoms leading up to this engine failure. The symptoms of struggling to start and the ticking noise as 2200 to 2700 rpm started that weekend before I brought to dealership. They got progressively worse. Dealership has said I will receive a new engine under warranty but no timeline for completion. Additionally I have not been furnished with a service loaner or option for one. Leaving me with no vehicle to replace it. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

4 Engine And Engine Cooling problem

Failure Date: 08/16/2026

Catastrophic engine failure - chevy, Silverado 1500, 2023; odometer: 33,183: on 8/16/2026 we were traveling down a busy highway towing our camper and the engine completely stopped, no propulsion, no warning lights, no check engine lights; complete failure; we had to coast to side of road. The only thing that indicated a problem is that we started hearing what sounded like marbles rattling, it wasn't loud but noticeable. We pulled over at gas station to check oil, even though we just had the oil changed for maintenance on 7/17/2026 (odometer: 32,587). Everything checked out ok; however, the marble sound became louder; then within 5 minutes of leaving the gas station, we lost all engine propulsion; the engine completely shut down. Our safety was put at risk as we had no truck engine and were towing a camper on a busy highway; and had to try and coast to a safe location on side of road; miles away from home. We had to call a tow truck to come get us and unfortunately, they could not help us with our camper so then had to call our son to come with his truck to get our camper and us home safely. The tow company also had a difficult time getting the truck into neutral to tow. The truck was towed to our hometown chevy dealer. The dealer said that they were not going to diagnose the problem and instead are ordering a new 6. 2 engine; same as the 6. 2 that failed. We asked if this would fix the problem and they said there were no guarantees as it is the same engine with the same problem. Prior to this event, we received a recall in Sep 2025 and an engine inspection and oil change was performed on 9/12/2025 (odometer: 25,751); we were told that our engine was ok. As of 9/3/2026; we have been without our vehicle for 17 days.

I was driving my 2023 Silverado 1500 down the highway when my engine started loosing power and then shut completely down at 65 mph. My safety and others were at risk due to speed and loss of power. I was lucky enough to not be on an interstate or in a metropolitan area. This happened due to a recall on this particular motor from general motors (6. 2 liter).

Failure Date: 07/24/2026

Engine failure on our 4-cylinder- it just quits same problem as on the 6-cylinder - it just stops running or runs rough. No warning signs and no indication that it is about to fail. Hazardous on the freeway. Vehicle has been at the mechanics for a month now and gm keeps saying the engine is on backorder.

10 Engine And Engine Cooling problem

Failure Date: 07/17/2026

Engine failed and was replaced at 38k. Transmission shudders, have been back to dealership multiple times for transmission shudder, have been told it was tires, torque converter, and valve body. When those items didn’t fix the issue, I was told it was the engine dfm and that it was normal and not a problem, after they had already acknowledged the transmission issue by trying to fix it with a torque converter and valve body. Engine failed again at 54,604 miles while at high way speeds in rush hour like traffic in between [xxx] and [xxx], while pulling a camper. Truck oiled down the interstate and produced a blueish/milky looking cloud that caused drivers behind me to lock up their brakes because of bad vision, creating a hazard. I was told by gm that they wouldn’t tow the camper that I had to take care of that but they wouldn’t tow send a truck for my truck. Tow truck gets there and says my truck is too big and leaves. I called my own rollback to get my truck 3 1/2 hours later and they came and got it. Was stranded on the side of the interstate for 4 1/2 hours in 90 degree weather, to my knowledge the 2nd truck gm was supposed to send never showed up. Requested a buyback and was denied with no reason given. I have a lot of records if anyone wants them. [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

11 Engine And Engine Cooling problem

Failure Date: 07/12/2026

On Sunday, July 12, 2026, the 6. 2l v8 (l87) engine in my 2023 Chevrolet Silverado 1500 zr2 seized and locked up completely, resulting in total loss of propulsion. I was driving at 65 mph when it felt like the transmission was slipping and I lost power and coasted the truck to the side of the road. Component: engine (6. 2l v8, rpo l87) — connecting rod/crankshaft failure consistent with safety recall n252494001 (NHTSA recall 25v-274). The vehicle is available for inspection. It is currently at cable dahmer Chevrolet, where it was towed on July 13, 2026, and remains inoperable. Safety risk: the engine seized during operation, causing sudden and complete loss of propulsion in traffic. This is the exact failure mode identified in recall 25v-274 as increasing the risk of a crash. Critical detail: this vehicle previously underwent inspection under safety recall n252494001 and passed on Feb 3rd 2026 at van Chevrolet in kansas city. Gm deemed the engine non-defective and issued extended warranty coverage of 10 years/150,000 miles under the associated special coverage program. Despite passing gm's recall inspection, the engine suffered catastrophic failure. This appears directly relevant to NHTSA's open recall query regarding the effectiveness of gm's recall remedy. Dealer confirmation: a technician at cable dahmer Chevrolet has verbally confirmed the engine is locked up/seized. Formal diagnosis is pending master technician sign-off and submission to gm, expected the week of July 20, 2026. The manufacturer has not yet inspected the vehicle. Warning signs: no warning lamps, messages, or symptoms appeared prior to the failure. The engine failed without warning.

12 Engine And Engine Cooling problem

Failure Date: 07/05/2026

On our way to [xxx], we heard a clacking noise coming from our engine. Pulled off the highway and had it towed to reeder Chevrolet. It was Sunday xxx. On xxx we went to the dealer and they said we spun a connecting rod bearing and needed a new engine. Truck is a 2023 slverado, 5,3 engine, with about 65000 miles on it. 5000 miles out of warranty. It took 18 days, and cost $12,214. 37 to replace. Dealer stated that if I wanted to pursue a warranty claim, we would have tpo pay for them to disassemble the engine, diagnose the problem, then reassemble the engine, and they would send it to gm. Gm would decide if it would be covered under warranty. If not, we would be out the cost of the diagnosis. I have always used 0w-20 full synthetic oil when an oil change was required. After searching this problem online, I found a tech service bulletin changing the requirement to 0w-40. We were never notified of the change, and the 2026 owners still say to use 0w-20. Attached are the invoice and recommendation to replace engine. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

13 Engine And Engine Cooling problem

Failure Date: 07/03/2026

Engine stopped while driving. Truck made dinging noise. Dash had no warning lights. Dash said need to press start button to turn on. Truck went into neutral by itself.

The motor has already been replaced once before at 4070 miles.

14 Engine And Engine Cooling problem

Failure Date: 07/02/2026

I drive a 2023 Chevrolet Silverado 1500 3. 0l diesel with the 10-speed transmission. The transmission control software failed to monitor/detect valve body wear or trigger a 5th-gear 'limp mode' safety net, resulting in three separate instances of sudden rear-wheel lockup at speed. The dealer was unable to replicate the issue during a service visit from 6/10 - xxx. The issue was raised as the transmission was shifting increasingly badly leading up to this service visit. The first full lockup occurred a few days after receipt of the vehicle on xxx driving eastbound on [xxx]. Off the gas, coasting downhill. Once everybody started speeding up, I increased the throttle gently and the truck shook violently. I initially thought I had been hit by another vehicle but realized it was the transmission. Speed was noted 24 mph. The second incident occurred xxx while traveling to [xxx]. Driving southbound between [xxx] and [xxx] at approximately 50 mph in a coasting condition. Went to pass a slow vehicle and the vehicle jerked violently an locked the rear wheels. Initial assumption was that I had been hit. Was able to regain control and continue. The third incident occurredxxx while traveling from [xxx] to [xxx]. Driving eastbound on [xxx] at approximately 35 mph, when moving from a coast to acceleration posture, the vehicle again locked the rear wheels and jerked violently. Finally, onxxx when traveling southbound from [xxx] to [xxx], I stopped for fuel. When attempting to accelerate onto the freeway, the vehicle failed to engage 6 gear, stumbled, and then went into limp mode with a check engine light. On xxx a [xxx] dealer found code p0747 and addressed the issue with [xxx]. I was forced to rent a car to continue my journey to [xxx]. Gm ultimately shipped my truck back to me one week later. The software 'fix' clearly did not work as intended and remains a serious safety hazard. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

15 Engine And Engine Cooling problem

Failure Date: 06/30/2026

A valve on the 3. 0l duramax is allegedly sticking, causing the vehicle to go into limp mode or be inoperable. This is a known issue for gm and they have issued a service bulletin on it. Unfortunately, no dealers want to address the issue and now we are left with a vehicle that if we do not pay to repair, after it being ours for only 5 days, the vehicle will be unusable. This vehicle is under warranty still and this part is needed for operation. I believe this avoidance of a recall is harming customers and creating pay to drive schemes. This needs to be addressed before thousands of customers begin paying for a repair that gm knows is their fault.

16 Engine And Engine Cooling problem

Failure Date: 06/27/2026

On June 27th 2026 at approximately 3am, I was driving my chevy silverado trail boss with 6. 2 engine, it suffered a sudden catastrophic failure and it completely seized while in motion. There were no warning or signs given while vehicle was in motion. This resulted in an immediate highly dangerous loss of propulsion on a dark 2 lane road. The vehicle would not crank and had to be towed to estero bay Chevrolet.

17 Engine And Engine Cooling problem

Failure Date: 06/26/2026

After the recall was done on my truck, it now makes a ticking noise that wasn't there before. When I bring this to the attention of the service department at the dealership where I purchased it, they say that noise is completely normal and sent me on my way.

18 Engine And Engine Cooling problem

Failure Date: 06/26/2026

My truck had done the oil update and pico test per gm’s requirements before I had bought it in October of 2025. 8 months later and about 15,000 miles, the engine seized and needed to be replaced. The new engine went in, in late July of this year.

The failure mileage was 54,000.

20 Engine And Engine Cooling problem

Failure Date: 06/20/2026

My second motor blew up while towing my camper with my entire family in the vehicle, leaving us stranded 1 foot from interstate traffic for over an hour as we waited for a tow truck—this was gm's 3rd attempt to fix the problem. There were no warning signs. The motor had roughly 4 thousand miles on it. I have since gotten rid of this truck (and suffered financial loss) before it gets me or someone else killed. Gm needs to fix this. O30,317 miles – started using heavier oil 6/18/2025 o36,732 miles – recall “fix” 11/10/2025 o38,917 miles – 1st engine failed 1/9/2026 otruck returned to me – 1-24-26 o43617 miles – 06/20/2026 replacement motor blew up I can't remember the exact speed, but I was going with the flow of traffic, so I'm going to guess it was 70-75. The file ctcs654636 is the second motor failure. Starr ro 626023. Pdf is the first engine failure. And I have also uploaded the two files of when I swapped oil and had the recall fixed.

21 Engine And Engine Cooling problem

Failure Date: 06/15/2026

On Monday, 6/15/26, with approx 45,400 miles, I was driving down the road and truck said service transmission. The gears would shift, but it lagged a little bit. I scheduled an appt for two days later, and only drove it when I absolutely had to, which was only twice before my scheduled appt. I get in it to drive and it says service transmission- unable to shift soon, then on my way to the dealership, it says all of that, plus service driver assist system. Chavy's quality assurance team needs to get it together! this is absolutely ridiculous.

22 Engine And Engine Cooling problem

Failure Date: 06/14/2026

My truck has the l87 motor on recall. I purchased it brand new and paid top dollar for it. I've had issues since I've bought it. All of my maintenance has always been done at the dealership from regular maintenance to purchasing brand new tires. I am very disappointed to have a truck that concerns to drive, I do not take my family out in my truck because I am not confident in its reliability and safety. Multiple times I've taken my truck in for service and let them know to complete an oil change, tire rotation and to check an issue with a "tick, clunk and knock" just to be told it was "normal for the 6. 2". My normal dealership has blocked off appointments online and you'd have to call to try to set one up. I demanded a diagnostic one time when the truck was acting weird and the tech stated "stop by, I'll squeeze you in" in which I did. However, I wasn't given any documentation since "I didn't have an appointment". After reviewing all of my service records, I come to notice not once time did they mention they did a diagnostic check. Only the recall test shows on one of the service records. I've had 3 different viscosity oils in my motor from the dealer stating gm recommended it. I had to night drop my truck on June 14 as it was making a weird noise from the engine and it felt like it had less power. I waited 2 days and the dealer did not contact to even state they have my truck in service. When I called to ask the status I had to agree to text message communication in which they replied, "at best it will take 2 weeks just to look at it". I asked for a loaner since I need a truck for work and transportation, they replied they do not have any and I will be placed on a list. My truck is still under original powertrain warranty and they cannot even provide a loaner. I feel that they are brushing me off to buy time and here I am making hefty car and insurance payments for a truck I do not have nor a truck that I need to provide for my family. Gm does not care!.

23 Engine And Engine Cooling problem

Failure Date: 06/12/2026

6/12/26 ( 2023 chevy silverado - 6. 2 liter engine) while driving at approximately 40 mph on a two lane road, the truck shut off. After multiple attempts, the engine failed to restart. The transmission locked up in park and would not release. This required the truck to be dragged up on the flat bed wrecker instead of rolling freely. Prior to this instance there have been several issues with the electrical system. 1. Radio sound shuts off. Does not come back on. 2. Head lights stay on for 10 minutes after vehicle is turn off. 3. Tail gate opens on it own. Tail gate doesn't open with fob. 4. Door locks fail to operate correctly. 5. When drivers door is opened a beeping sound starts and doesn't stop until door is closed. I have reported these problems to gm & have two case numbers. The dealership reports that the 6. 2 replacement engines have had multiple failures.

24 Engine And Engine Cooling problem

Failure Date: 06/06/2026

Engine failed and no light or warning besides check oil was shown on truck. The electrical system also went out (a year before engine failure) so car wouldn’t start.

25 Engine And Engine Cooling problem

Failure Date: 05/29/2026

I was travelling on the highway at approximately 72 miles an hour in the left lane trying to pass a vehicle in the right lane. While accelerating my truck was like the brakes were slammed on and all kinds of lights starting flashing. This included the check engine light, low oil pressure light and lane assist lights. The truck shifted into neutral and I could not place back into drive. I swerved and almost lost control of the vehicle and nearly missed colliding with the safety rails on the left of the road and then with the car on the right side. I then pulled onto the shoulder after nearly being rear ended by another vehicle approaching on the left. The vehicle would not react to the gas pedal. I pulled onto the shoulder and turned the vehicle off. Tried to restart but again nothing but mutliple lights and warnings. I checked my app for Chevrolet and it stated that the vehicle needed engine and transmission system service. Variable valve timing system needs serviced. Ingition system needed serviced. The onstar diagnostic alert indicated p0016 was detected. I opened the hood to inspect and the coolant overflow was spewing coolant. I checked the oil level at that point and it was just a little below full. I had taken this vehicle into the dealership two other times stating that the vehicle had stalled before on the highway but not to this degree. The other two times it stalled when accelerating it would allow me to pull over and restart. But both of those times I never had any flashing lights or diagnostic codes. I explained this to the dealership and how unsafe it was. Both of those times almost ended in a vehicle accident with other vehicles around me. The dealership said they could not diagnose any issues unless the truck created a diagnostic code. These issues have been ongoing with these vehicles for a long time and the dealership just did not want to deal with them. I had the vehicle go thru the recall diagnostic tests. It did not fix them.

26 Engine And Engine Cooling problem

Failure Date: 05/27/2026

While driving, the vehicle suddenly displayed “service esc” and “service traction control” warnings. Shortly after, the engine stalled and the vehicle became difficult to restart. Vehicle experienced rough running/misfires and loss of power. Diagnostic trouble codes retrieved included p0300, p0106, p3498, p00ff, and u1962. The issue appears intermittent but creates a serious safety concern due to unexpected stalling while driving. Concerned about possible electrical, engine management, or stability control system failure affecting safe operation of the vehicle. No prior warning before incident.

27 Engine And Engine Cooling problem

Failure Date: 05/21/2026

What component or system failed or malfunctioned, and is it available for inspection upon request? engine seized and vehicle was towed to dealership. It is available for inspection. How was your safety or the safety of others put at risk? loss of propulstion, described below. Has the problem been reproduced or confirmed by a dealer or independent service center? yes, dealership where originally purchased. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? inspected at dealership by gm/Chevrolet technician. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? none prior to failure detailed description: on 5/21/2026, during normal driving, the engine in my truck lost propulsion due to a major internal failure. This is a 2023 general motors 6. 2l (l87) engine that was inspected at the dealership where it was originally purchased for the previously issued NHTSA "loss of propulsion" recall and passed without any noted issues. This engine only has ~20,000 miles on it. The engine failed in relatively heavy traffic and could have easily resulted in a serious accident due to inability to route my vehicle to a safe area while under power. This all happened without any prior warning, no check engine lights, noises or lamps or symptoms. The dash simply illuminated with a "press start" message. The truck was towed to the dealer for evaluation. The dealer called me today (5/26/2026) stating the engine was seized and a new engine would have to be ordered from gm for installation. This event occurred while the vehicle (2023 silverado zr2) is still under the original 36 month/36,000 mile warranty.

28 Engine And Engine Cooling problem

Failure Date: 05/20/2026

While traveling on the interstate towing a fifth-wheel camper going 55 mph, a message appeared on the dash instructing me to press the start button. I pressed the start button, but the vehicle would not start. When I pressed the start button the entire instrument cluster and navigation display went out. We were able to safely coast to the breakdown lane, skidding to a stop. We remained in the breakdown lane on a busy highway on a holiday weekend in 90+ degree heat for 7+ hours before being towed to a nearby dealership. When the right type of tow truck arrived (capable of towing the truck and camper off the highway), the driver had to remove the driveshaft before the vehicle could be towed to the nearby dealership. This is because of the electronic shift. If the vehicle is not running it cannot be shifted out of park without a special tool. We felt very unsafe sitting in the breakdown lane with cars whizzing by shaking our camper and vehicle at each vehicle passing. Not 1 time did the police stop to provide assistance/make sure all were ok, etc. The vehicle has since been towed to the local dealership and after they inspected the vehicle it was determined the engine seized due to debris in the engine. A replacement engine is on backorder. The engine had already been inspected for the recall and gm 6. 2l l87 "fix" was performed, but this did not stop the engine from seizing.

29 Engine And Engine Cooling problem

Failure Date: 05/13/2026

At approximately 24,000 miles the engine had catastrophic failure under normal street/highway driving conditions. The engine is the 6. 2l v8. The issue began with a high pitch squeal or chirping sound and noticeable power loss. I parked the truck over night and then drove it to the dealer first thing the next morning. While on the way to the dealership, which was less than 20 miles away, the engine began having much bigger issues. A loud knocking noise was apparent and the rear end began locking up causing the tires to also lock up. Once at the dealership the engine completely failed and locked up. The engine did have the newly recommended 0w-40 oil installed prior to the failure.

31 Engine And Engine Cooling problem

Failure Date: 03/26/2026

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.

32 Engine And Engine Cooling problem

Failure Date: 03/22/2026

34 Engine And Engine Cooling problem

Failure Date: 03/20/2026

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.

35 Engine And Engine Cooling problem

Failure Date: 03/20/2026

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.
