I had the gm 6. 2l motor recall test, it passed. Catastrophic engine failure at 50mph roughly 6000-7000 miles later. Luckily I got off the road safely. Confirmed by gm dealer, new engine has been ordered. No warning lights.

The oil cooler lines cracked due to cold weather and oil spouted out of the engine. Truck was immediately pulled over when the chime went off, however the engine still seized up and needs to be replaced. No warning lights before, just the chime at 0 oil pressure. I see that canada and alaska has this part recalled and I want to know why it’s not recalled everywhere. No oil was leaking prior to this incident. This left us stranded on the side of the highway and we now have to purchase a new engine with only 65,000 miles on it.

The engine coolant control valve went out on my vehicle. It is an 2022 lm2 engine. I found that that part frequently goes bad prematurely on this model. I also determined that this should be covered under n252508341. I was told by gm customer support that based on my VIN it is not covered and they would not give me any further information. This is outrageous as this is the same defective part covered on their extended warranty.

Engine was running at the mechanic shop after getting serviced for spark plugs ,wires, new radiator was installed,and transmission service. The engine was running on the lift for the mechanic to top off transmission fluid. The engine stop by itself. Went to restart the engine no start just extending cranking. The mechanic shop has the truck trying find the issue why did engine stop while running.

Brought my 2022 chevy silverado 6. 2 l engine into dealership for safety recall n252494001 l87 engine loss of propulsion. Engine passed this initial inspection, oil, oil filter and oil cap was changed and was sent on my way. February 4th, 2026, engines lost propulsion while traveling at highway speed, (75mph) causing a serious safety concern with rush hour traffic. After pulling over to the side of the highway, I reset the truck by cycling the ignition and was able to start the truck. On February 5th, 2026, engine lost propulsion again at neighborhood speed, (20) in a construction site. Truck was blocking traffic at this point. Engine was unable to be started, transmission was locked in parked and unable to be shifted. Had to have truck "dragged" out of traffic. Dealership was notified that I had possible catastrophic engine failure. I was advised by dealership to have it towed, at my expense to them. Truck was towed at a cost of $196 out of pocket. Tow cost an extra $50 due to the electronic shift no allowing for transmission to be shifted into neutral or linkage to be released by tow company. February 6th, 2026, dealership notified me that the engine had a catastrophic failure and would need to be replaced. Dealership has motor but trying to source one time use parts that were currently unavailable. No time frame given on sourcing those parts as of February 10th, 2026. Dealership/gm arranged for a rental car but financial limits set by gm does not include the ability to be given a truck as a rental. I am in construction and need a truck and have a once in a lifetime trip coming up March 13th. I am in need of a truck for the trip to haul my sxs and gear to another state. Very frustrated at gm for doing a piss poor job on rectifying the engine issue in the l87. The personal safety of loosing engine propulsion at 75mph during rush hour traffic could have ended in a bad accident.

On 2/5/2026, the 6. 2 liter l87 engine in my 2022 zr2 silverado locked up and is currently located at edwards Chevrolet on highway 280 in birmingham, al. While on I-65 in birmingham, al. And prior to locking up, the engine power decreased, and rpm's increased, followed by a dash message that oil temperature is high; pull over and idle. After idling the engine the dash message disappeared and oil pressure was good. We drove approx. 1. 5 miles to a parking lot where the engine seized or locked up. The truck was towed to the above referenced dealership. The dealership confirmed the engine was locked up the next day. During the summer of 2025, the dealership inspected the engine and performed an oil consumption test after I reported the engine had burned two quarts of oil between oil changes. Their fix was to transition from 0w-20 to 0w-40 oil, which has been adhered to since. The truck only has 56,000 miles on it.

"approximately four months ago, I noticed an oil leak coming from the midsection of the engine/transmission of my 2019 chevy silverado ltz with the 6. 2-liter engine. At the same time, I noticed a slight knocking or rattling noise coming from, I believe, the front of the engine. Upon taking it to the dealership, they replaced the engine oil coolant lines, only to find out that the engine was still leaking oil and still making the knocking and rattling noise. They then discovering that it was the rear main seal, they have since replaced it about one week ago. Yesterday, February 6th, about 12:15 pm in the afternoon, while I was getting off the I-405 in renton washington and merging onto the southbound lanes of 167. I was in the left lane and I made it about a quarter mile down 167 doing about 60 to 65 miles per hour and I lost power suddenly. As I started to merge into the right lane, I noticed the engine light came on, and then the truck seemed to kick down into first gear while I was doing 50 miles per hour, which instantly slowed it down. This forced me to cross over an on-ramp lane to get to the shoulder and come to a complete stop. After that, the truck would not start at all. I then had to sit on the side of the road for three and a half hours waiting for a tow truck to take me and my truck back to the dealership, which is also the same dealership where I bought the truck back in 2019. They have not diagnosed it yet as I just dropped it off at 4 pm on 2/5/2026. My truck has approximately 155,000 miles on it.

As I was driving my 2021 Chevrolet z71 pick up I had a warning light appear on the dash indicating the safety traction control system was faulty, at the same time my truck had a loss of power as if it was not operating on all cylinders. I could hear some strange noises that were not normal, at the same time my transmission was shifting abnormally. I managed to drive to a dealer and was told it was a collapsed lifter on cylinder #5 this occurred out of no where, I was informed what took place could have damaged the camshaft and I could be looking at a repair cost upwards of $5,000. 00 and the service writer indicated this has been an ongoing issue with the 5. 3 liter engine. My truck has been serviced at the dealership it was purchased from, and all oil changes have been performed within a reasonable window from when oil changes and service inspection has been recommended by general motors.

I was driving on the highway and there was a sudden drop in power and hesitation in the engine. I slowed down too quickly on a busy highway and almost got rear ended. I took it to the shop and found out I had to replace the engine due to the cam and lifters were bad. It cost $12,000 to replace a four year engine with 148,000 miles. The time before that this happened, I had to replace the engine wiring harness.

On febuary,3,2026 I was traveling down a local highway at 50 mph when I felt a sudden power loss and heard a squeaking noise figuring something was wrong I pulled over at the next safest spot, while pulling into the spot the squeaking noise developed into a "rod knock" the sound a loud metal clattering noise that was consistent with the rpms. I immediately shut the vehicle off and called a local towing service who promptly dropped it at my local chevy dealership the night of febuary,3,2026. Further contact was made with dealership the day of febuary,4,2026 regarding the issue , prior to this issue the truck had been in for the recall regarding the l87 6. 2 liter engine and it had passed the inspection and was given the oil change and the new oil cap and owners manual.

Afm lifters has failed in my vehicle 3 times as of date. Being that its a costly repair this should be recalled. Information provided is the latest mileage.

My truck took my truck to austin and back. Woke up the next day. Started it at approximately 4 o'clock in the afternoon and had engine oil low alert. Got out check the oil in my truck and there was none on the dipstick with the truck off of course. Checked at two other times allowing the dipstick to stay in for three or four minutes. Still no oil on the dipstick. Did not drive truck any further. Truck has the 6. 2 l and I had the recall applied to the truck on December 8. The truck has 88% of the oil life remaining according to the truck.

I just bought this truck off a used car lot certified dealer and I noticed the engine light on then the truck would hesitate to start and I know the battery is dying so I looked it up and I got a recall on 2021 chevy silverado just like mine just wondering why mine is not under recall or why won’t mine get fixed but everybody else is the same year in the same problems can get fixed. I think mine should be fixed.

As I was speeding from the fast lane to get across to the right lane off ramp when my vehicle suddenly shot off. I knew I couldn’t stop on the off ramp or on the bridge I was on. Luckily I had a green light at the top of the off ramp and coasted to an empty parking lot. Once I came to a complete stop I attempted to restart my truck but no luck. The truck would not even crank over. I tried multiple times and the dash would only go dark for a few seconds and I would try again to start and had no luck. Called aaa and they thought it was a battery so they put a jumper and same thing, no crank. Then they tried jumping it with jumper cables and still no crank at all. I had just installed a new battery no more than 4 months ago and my headlights, interior lights all are working fine, no dimming or anything like that. I just had an inspection on the engine last time the truck was at the dealer and they said everything was fine and they put a new oil cap and thicker oil. I think this is related to the safety recall chevy just performed. This is a huge safety risk, I’m lucky I was able to pull off the freeway when this occurred. It’s not normal for a vehicle to just shutoff on you at freeway speeds.

My husband was driving on plank rd/rt 219 towards ebensburg PA when the truck started to buck and he turned off the main road and it shut down. It would not start just said low battery. I had it towed to the garage we use. They just confirmed it is the engine it locked up. I had the inspection for the recall and had the oil changed prior to this happening.

We own a 2020 silverado with a 6. 2l l87 engine… I am aware of open investigation # ea25007… our vehicle had sudden engine failure. . No prior warning lamps before failure. (our vehicle had no open recalls) once vehicle engine failed left us with no power… had to coast vehicle to a stop. Will not restart. Verified proper oil level on dipstick so vehicle was not low on oil. Had to tow vehicle to shop . . Retrieved code p0016 - crankshaft position oil pan was removed and found bearing material as mentioned by gm issued recall 25v-274. Verified oil pickup tube was not clogged. All symptoms explained by 25v-274, we’ve experienced.

Transmission warning light came on the dash saying may not be able to shift soon. I dropped of at the dealer and they said they were backed up on that department I would have to leave it there and they would diagnose in a week and let me know. Still waiting 6. 2 zr2.

Starting back in June 2025 loss of engine power multiple times. Many times almost hit from behind as I turned onto a highway. Found out vehicle had a stop sale recall at the time of purchase and I had issues with back right tire. Took truck to a tire shop and learned that the wheel was welded in many places and fracture was visible. Finally, got the dealership to pay attention in October to my concerns. They were going to allow me to trade the vehicle out for another one while paying off the bank but that’s not what they did. They attempted the repair and tried to hand it back to me. 1/27/26 was recently told this was corrected, and the sales person told me when he picked it up from shop he couldn’t go more than 30 mph. Dealership management told him not to tell me. I am submitting this complaint for immediate review regarding ruiz ranch motors (spring branch, TX) for an illegal vehicle sale, prolonged withholding of my vehicle, misrepresentation of a “loaner” vehicle, and coercive threats involving law enforcement. This matter involves ongoing safety risks, financial harm, and improper dealer conduct affecting both myself and my minor child. Summary of key facts (concise): • on June 25, 2025, I purchased a 2021 Chevrolet silverado (VIN 1gcuyhet7mz155657) from ruiz ranch motors, financed through ally financial. • the vehicle was subject to a gm stop-sale / no-sale safety recall (NHTSA 24v797000) at or around the time of sale. • I repeatedly raised safety concerns beginning shortly after purchase. These concerns were dismissed for months. • in November, ruiz ranch motors took possession of my 2021 silverado under the representation that they were “working on trade numbers” and a solution to correct the experience. Misrepresented “loaner / trade” vehicle: • I was provided a 2023 Chevrolet silverado, represented as a potential trade option, no trade was made (only dealership delay) this vehicle now has a engine light and no cooperation from dealership.

Good morning, while driving and starting my chevy Silverado 1500 with 3. 0 durmax it will suddenly go into a “limp mode” reducing speed and power. Recently while driving on a highway it reduced engine power causing the vehicle to slow down suddenly with many cars speeding by. This caused me to try and pull over the vehicle and avoid hitting other vehicles. When pulling codes off the vehicle there is a p1098 which refers to the engine coolant control valve. This will cause the vehicle to do the described power reduction. Upon researching the issue gm has recognized and released a special coverage to fix the issue. N252508341. However my vehicles VIN does not pull up the coverage. All the characteristics of the coverage seem to fit the model and issues I have. It’s the same year, model, engine, etc. I’ve attached a dot report of the special coverage. I’m hoping this will help fix my vehicle and others with this same issue. Although it’s not specifically listed as a safety recall, I feel the cause of the sudden power reduction is known by gm and warranty issued and the problem should be resolved for all vehicles with this issue. Thank you!.

My 2022 silverado pickup with 6. 2 engine simply died as I was heading down the highway at 65mph. It was dark outside and I barely got it pulled over to side of road safely. Had to have it towed to chevy dealer. They weren’t sure what problem was— starter and battery indicated ok. However we had them install new ones just in case. We’ve seen on our searches of the internet that this is not a new problem. Just today it died again on me as I was driving in town, but did start again. I travel quite a bit and am worried it will die on me again in this crazy cold weather! chevy needs to acknowledge this issue with the 6. 2 motor! I’ve already spent almost $1500 on this issue and don’t think it’s fixed,.

At about 800 miles I noticed ticking from the engine and random and intermittent jerking. Some of which were very severe that felt like someone rear ended me. I took into the dealer with my complaints. They kept my vehicle for 2. 5 days and didnt give me a loaner. The my were unable to reproduce the jerking and said the ticking was normal. They showed me the ticking and said its normal and will go away after it warms up. They did a vehicle update and said it will help. They said theres nothing else they will do. I knew something was still wrong but felt like they wouldnt do anything and I couldn't give up my vehicle for days at a time. I continued to drive it and was planning on taking it to a other dealer for a check up. But at about 3500 miles. One day the truck began squealing and grinding. I attempted to drive the truck home and the truck just died on the freeway. Luckily I knew something was wrong so I stayed in the slow lane so it was easy for me to get off. Thats the first time the check engine light came on but it was too late. I had it towed to the dealer and they checked and it was catastrophic engine failure.

Collapsible lifter and lift rod failure.

On 1/21/26 traveling on a 4 lane divided highway, vehicle stalled, several warning lights came on and vehicle came to a complete stop in driving lane. Vehicle locked in park and could not put vehicle in neutral to push it out of highway. Several vehicle swerved to avoid and until tow truck came blocked a lane. It was about 3:30pm fortunately. So vehicle was visible and no accidents to our knowledge occurred. Thai created a dangerous traffic situation. It was caused by a fuel pump control module whig was repaired 2 days later at local chevy dealer. We were advised there were no recalls on this part but it is a common problem. Gm should somehow find a solution and repair said problem.

On Tuesday 01-20-2026, I was driving from dallas fort worth to oklahoma city, ok. I was driving down the highway I-35 at about 80 mph. Suddenly I felt a loss of power and my truck started to bog down. As I pulled over, the engine stalled out and would not start up again. It would crank but it would not start. My truck was towed to a dealership in norman, ok. "landers Chevrolet". I was contacted by the dealer the morning of 01-21-2026 informing me that my engine is going to need replaced. My truck is a 2026 Chevrolet silverado lt trail boss with 6. 2l and 6,457 miles on it. At this time, I don't have any paperwork or a copy of the repair order because the vehicle is still in the shop. The dealer told me that the motor is on order and should be here in 4-6 weeks. I purchased this vehicle on October 16, 2025.

The cam crankshaft failed. I was driving on the highway at a speed between 65-75 and my truck just cut off without any warning. Luckily, I was in far right lane and coasted over to the side of the road but it was very scary because I didn't control my truck at all. I called the nearest Chevrolet dealership that was kevin whitaker and they give me the Chevrolet help contact phone and they sent a tow truck to pickup my truck about 1 hr later and I was stuck in my truck on the side of the road and I couldn't get out on the drive side because how close it was to oncoming traffic. Once I arrived at the dealership with my truck after asking the tow driver could I ride with him to the dealership. At the dealership they checked the truck with computerized device and the service advisor told me the truck code revealed cam shaft problems. I told him that I did see and warning sign saying low oil pressure once I tired to start up the truck again on the side of the road.
