general problems of the 2022 GMC Sierra 1500 - part 2

The failure involved the engine (6. 2l l87 v8), specifically suspected internal components such as the crankshaft and/or connecting rods, as identified in a current recall. The vehicle is currently located at dennis gm in corner brook, newfoundland and is available for inspection. On March 9, while driving the vehicle normally on a main highway, the engine suddenly lost all power without warning. The accelerator became completely unresponsive and the vehicle rolled to a stop in the middle of a main highway. The engine would not restart. Due to the electronic gear selector, the vehicle could not be shifted into neutral, leaving both the truck and trailer immobilized in a live traffic lane. This created a serious safety risk to myself and other motorists, especially as I was in an area without cellular service and could not immediately call for assistance. The problem has not yet been formally diagnosed, as the vehicle remains at the dealership awaiting inspection. However, the symptoms are consistent with known failures described in the recall affecting these engines. The vehicle had previously undergone recall inspection on September 1, 2025 and was cleared at that time. The vehicle has been inspected previously by an authorized gm dealer as part of the recall process, but no defect was identified. It has since been towed to dennis gm following the failure and is pending further inspection. No police or insurance inspections have been conducted. There were no warning lights, messages, or prior symptoms before the failure. The engine failure was sudden and without any indication of an issue beforehand.

The contact owns a 2022 GMC sierra denali 1500. The contact stated that while driving at 73 mph the vehicle lost motive power. The contact was able to pull over safely. The driver was unaware of any warning lights being illuminated. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not notified. The failure mileage was unknown. The VIN was not available.

The truck currently has 48000 miles. The 6. 2l l87 engine was replaced at 17000 miles. A few weeks ago, I parked it, went to a ballgame, came back 4 hours later and started the truck. Drove it approximately 500 feet and lights started flashing on the dash. It was running rough, had loos of power, and sounded like a diesel. I immediately shut it off and had it towed to a dealer. The lifter on the number 3 cylinder stuck and bent the pushrod. The dealer replaced all lifters on that side of the engine. This all happened after it was checked for the recall and the thicker oil was put in.

The motor stoped working 6. 2. Left me stranded in the middle of the road. No warning, the engine just gave up and stopped working. As well as the grill flying away and breaking my windshield, this happened last year in February while driving 75 mph.

Motor was replaced at 70000 miles it blew rear main on the technician. Now 30000 miles later saying it needs valve body its been in shop 5 weeks now and no eta on parts. Also the onstar module went out or never worked after engine replaced. The truck has locked up 4 times before the engine was replaced once at 11000 miles. Had hard shifting issues from new dealership kept saying it just needed an update or tuned everytime until 100000 miles warranty was up. On my truck all the extras were were installed when they arrived. Heated and cooled seats. Heated steering wheel, park assist and something else however the truck was already out of manufacturers warranty before the 1st item installed at 50000 miles over a year after I had purchased. Everytime something was put on something else failed. And the grille started peeling immediately after I purchased vehicle and is almost completely gone.

The engine decided to make some noise and all I heard was ching ching ching, and it just died and I was unable to start it again.

No warning lights were illuminated. The vehicle was towed to the dealer, where it was diagnosed with engine failure. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The contact stated that the vehicle was repaired under NHTSA campaign number: 25v274000 (engine and engine cooling) in February 2026. The contact stated that a picoscope test was performed. The contact was informed that the vehicle passed the inspection. The manufacturer was made aware of the failure, and a case was filed. The failure mileage was approximately 41,200.

My GMC sierra denali 2022 equipped with the 6. 2 motor locked up while I was driving pulling me out of the road.

My GMC sierra had no warning lights, on the way to work on the highway it started making noises which increase every mile . Vehicle just turned 60. 049miles . Engine completely seized up , low oil pressure light on , vehicle shuts off , luckily making to the shoulder and off the road. Gm towing wasn't any help in middle of the winter with 0° outside that morning , they told me that it's not covered under warranty and it would take 3 hrs for towing to get to me and out of my packet cost . Dealer diagnosed issue , found code p0016 (crankshaft position-intake camshaft position not plausible) also found excessive amounts of metal in the oil. Vehicle was repaired and second engine was installed .

The coolant control valve failed. This is a known failure point of poor design and on every other truck from 2019-2023 with the duramx lm2/lz0 engine, they are covered by a special service warranty to 150,000 miles. Gm knows this items fails and puts consumers lives at risk when the failure throws the truck into limp mode on the freeway. They refuse to do a recall to avoid doing the right thing. This is deceptive and wrong.

The vehicle is subject to safety recall n252494001 (NHTSA campaign 25v-274) due to manufacturing defects in the engine crankshaft and connecting rod bearings. • component/system failed: the 6. 2l v8 (l87) engine crankshaft and connecting rod assembly. The engine is available for inspection upon request. • safety risk: the defect can cause catastrophic engine damage and sudden loss of propulsion while driving, significantly increasing the risk of a crash. • dealer/manufacturer confirmation: the problem was confirmed via the issuance of safety recall n252494001. A dealership inspection was performed previously as part of the recall. • warning signs/symptoms: common symptoms include engine knocking, check engine lights, and hesitation before sudden failure. The issue with the remedy: federal law (49 u. S. C. § 30120) requires manufacturers to remedy safety defects "without charge". As a permanent safety remedy for this defect, gm has mandated a switch from 0w-20 to 0w-40 (dexosr) oil for the life of the engine to prevent bearing failure. However, the dealership and manufacturer are refusing to provide this mandated safety spec change without an ongoing $85 surcharge per oil change. While they performed the initial "inspection" oil change for free, they are now using the recall-mandated spec change to create a financial burden on the consumer. Because 0w-40 is now the mandatory factory requirement to prevent the safety defect, charging a premium for it constitutes a failure to provide the recall remedy "without charge. " general motors refuses to offset this cost, effectively penalizing the owner for a manufacturer safety defect. The dealership is also failing to honor my platinum wrap warranty and gm prepaid service contract to perform the continued oil changes without additional charges.

While driving I get a reduced acceleration warning on my dash cluster, drastically reducing horse power. My check engine light came on. This has happened before. I checked the code and it was a p1098 code. After researching I found out it was the engine coolant control valve. My fan is constantly running. This issue is ongoing. This seems to be a common occurrence with my vehicle year.

This is separate for VIN 3gtuudel5ng657492 I had to change dealerships because beck & masten south / GMC would not provide me with a loaner after being told I was on the list and I was next in line. I waited a month and drove to them and spoke with the girl who oversaw loaners. I explained I had severe safety issues such as front-end wobble which is related to transmission issues. And the oil consumption issue and oil light. Once again, I was re-assured the loaner program was indeed still active and I would be put on priority. Again to no avail I had wasted too much time with beck & masten. After months of this I found out I did not have to take it to the dealer I bought it from. So, I took it to monument Chevrolet. I explained my concerns related to the front-end wobble which was very intermittent. And the oil consumption issue which I was very concerned with due to the year model and mileage of the truck. Also, the 75,000. 00 price tag was really has me extremely upset. . . Monument Chevrolet treated me well. I had actually brought it in and called about the steering which was greatly affected by the severe front end wobble more than one time. I was told at first the oil consumption was pretty normal. Until I told them how much I had to add between changes. I have attached two work orders to this complaint. These work orders show what was done at 18017 miles and 18323 miles. The later work order was when the pico test was done. Also, an oil consumption test was started once I picked the truck up. After I had driven it for 2077 miles and was bringing the vehicle back to monument Chevrolet, as instructed for the oil consumption results, when a loud squeeling, then hard knock, power loss and I pulled over. I called monument and was instructed if I could get it to start and bring it. I drove it to them while knocking and rough running. It has been in the shop for over 2 months for an engine replacement. 2077 miles after recall work! refer complaint 11729716.

L87 catastrophic engine failure on second engine after 6300 miles. This is the second issue with the 6. 2l engine in my Sierra 1500. The first engine passed the l87 engine loss of propulsion field action and then suffered catastrophic engine failure a month later. The replacement engine procedure took over 3 weeks to perform and no rental or loaner vehicle was provided by gm or the servicing dealership. The vehicle is currently in the service department at another dealership awaiting the 2nd engine replacement, but it has been over 2 weeks since the engine failure. This servicing dealer has provided a vehicle to use. This has been a very frustrating ordeal and I feel that resell and value of this vehicle has been compromised and gm has done nothing to offset this with me.

Engine recall 6. 2 l-87 , after pico scoop test, which my truck passed, its using 2 plus quarts of oil per 1000 miles, the dealer has it and is saying they can find nothing wrong per the gm tech that is telling them to check this and that. Ok, oil is going somewhere, I want the motor replaced , they want to continue the oil consumption test, my thing is wasting my time to continue driving and bring back to it back for a low oil reading, its not gonna fix its self by driving it. I understand gm wants to figure out why, but it should not be at customers time , replace the motor all ready, something is wrong. The first 1000 miles after a oil change and they put die in the oil to check for leaks. When they check the oil level Friday 02/06/26 the oil did not read on the dip stick.

54k miles. Crankshaft failure. Truck shut off and put in neutral while driving with no codes on dash. Got a text saying to service engine and transmission immediately. On a side note, it is bullshit that you can't put the truck in neutral to get it off the road. The dealership is also doing a great job covering it and offering a loaner.

No warning. It’s been replaced by gm and a week later now it’s in the shop again because it’s acting up.

My vehicle stop running as I approached a traffic signal and failed to restart, it happened at a heavy traffic intersection during morning commute,I had the vehicle towed to dealership that same day (01-22-2026). Later that evening the dealership called to inform me that the motor was blown and had ordered a new one. The mileage is approximately 39,285.

To start off my truck has been to the dealership multiple time for the camera. After third time in the shop they fixed that issue. Then the infotainment started acting up after about 4 times in the shop it was fixed. They gave me the prescribed fix for the engine recall in November. Engine passed the test. Then 3 weeks ago the engine siezed up from the crank and bearings on the interstate doing 70 pulling a trailer in traffic. Leaveing me and my dad in the middle of the interstate. I had to have it towed 2 hours to my house. After the prescribed engine fix. They replaced the motor in 3 days. Great right? no they did not test drive long enough. Or they would have felt the shudder that developed after the new engine went in. It is now about to go back to the shop. Because of the shudder at low rpm and im haveing electrical issues again as well . My remote start also stopped working after the engine replacement.

I purchased my vehicle in June 2025. In January of 2026 the vehicle would sometimes shut down at red lights, requiring me to restart. No engine codes would pop up. On Jan. 16th, 2026, I exited my vehicle and heard a “cow bell clunking” coming from the engine area. I scheduled a service, and I was informed that the issue was part of the gm recall for 6. 2l engines. This concerned me, because my vehicle had already had the “remedy” for the recall (changing engine oil type) prior to me purchasing it certified pre-owned, and the engine still failed. The dealer I brought the truck to did a full engine (and appropriate parts) replacement as part of the open recall.

After I had the car inspected per thier recall on potential engines issues, the car passed and was told no issues. 6 months later driving on highway with family during rush hour and suffered complete engine failure going 70 mph. Lucky not to have been hit from behind. Scary to be on highway like that. It was freezing outside. Dont understand being told car is fine and then this happens.

My gm dealership completed the gm 6. 2 engine inspection and recommended oil replacement as part of the 6. 2 engine recall. Roughly 5,000 miles after this service, the engine failed. I attempted to accelerate from 45-65 miles per hour while getting on the highway, and the engine seized up. I was able to coast/steer the vehicle to the side of the road. The vehicle's starter could not crank the engine. I had the vehicle towed to the shop where the dealership confirmed the engine had seized. The dealership and gm replaced the engine under a warranty repair. I am making you aware of this situation, as the manufacturers suggested solution to the engine issue (the change in oil type, filter and cap) did not prevent the engine from failing.

My 2022 GMC Sierra 1500 at4x experienced an engine failure requiring full replacement under warranty. The vehicle was out of service for approximately 46 days. After replacement, the vehicle experienced additional electrical issues and unsafe operating conditions. The replacement engine has now failed again in under 8,000 miles. A dealership performed diagnostic testing (pico scope) which failed immediately and recommended another full engine replacement. I have been advised not to drive the vehicle due to safety concerns. This appears to be a repeat defect that was not corrected by the initial repair.

The lifters stuck and it ruined the cam shaft. This was repaired and then when driving home, the engine seized and started smoking. The engine was then diagnosed with complete failure and it had to be replaced. The engine had been upgraded a year or two earlier to the 0w-40.

Bought truck 0n 12/26/2025 from lot in michigan had it transported to missouri. First time I drive it check engine comes on and goes into "limp mode". Had it towed to gm dealer and they say it was the high pressure fuel pump. Got it back and check engine light comes back on then goes off then back on again. Not happy at all!!!.

Radiator is leaking where plastic meets metal. Leaking coolant at upper corner driver side. This is crazy for a 70k truck. It is a known problem. Dealer refused to submit a claim to gm. I am seeing people get theses replaced. It has been an issue since coolant control valve was replaced.

I had a lifter fail which is a well known problem for these gm engines. The lifter caused the cam shaft to be damaged because of the lobes being shaved off. Now I’m being told that it will be over $10,000 fix a 3 year old truck.

The contact owns a 2022 GMC Sierra 1500. The contact stated that while driving approximately 65 mph, the check engine and several other warning lights were illuminated. The contact stated that the vehicle almost stalled and then lunged forward. The vehicle was driven back to the residence, and a local dealer was contacted. The contact had taken the vehicle to a local dealer, where it was not yet diagnosed or repaired. The contact stated that the vehicle was repaired under NHTSA campaign number: 25v274000 (engine and engine cooling) by the same dealer. The contact stated that the dealer had tested the engine and added thicker viscosity oil. The contact related the failure to the recall work. The manufacturer was not informed of the failure. The failure mileage was approximately 25,000.

See attached document for complaint.

Engine seized while driving on my local interstate hwy. No warning lights came up. Towed to the dealer and they confirmed the engine was locked up. Engine needed to be replaced.

The engine was producing a strange noise while driving and subsequently shut off. The vehicle was towed to a GMC dealership where an inspection/testing was performed. Ultimately, I was told the entire engine needed to be replaced.

Complete engine failure, at 57,000 miles, was driving approximately 75 mph on the I-15 in utah outside of st. George, and the left lane, engine turned off, was able to pull safely in a shoulder in a canyon with my family, my wife, my kids 8 and 10 years old. Vehicle was towed that evening at 7 pm to the dealership, where it was diagnosed with completed engine failure.

There was engine failure whereby the pushrods were ticking extremely hard. After towing the vehicle to the repair shop, it was determined that a new engine would be needed. The cost for repair was $11,500. 00 dollars. The original engine has approximately 75,000 miles.

On November 16, while driving on the highway, my GMC vehicle suddenly lost engine power without warning. I was forced to stop in traffic, creating a dangerous situation and putting my life at risk. The vehicle required towing and has remained at the dealership since that date. The dealership determined that the engine requires replacement. Repairs have been significantly delayed, including an incorrectly ordered replacement engine, and the vehicle remains out of service more than two months later. This defect caused a sudden loss of power while driving and presents a serious safety concern. After the incident, I contacted the dealership immediately. Diagnostic appointments were scheduled and then canceled by the dealership twice, which delayed inspection and repair. I was only able to leave the vehicle at the dealership on December 12 due to these delays.

The engine in my vehicle has failed twice while driving at highway speed. Both times, the engine suddenly stalled without warning, causing an immediate loss of propulsion, lighting, and steering assist. Each failure occurred at night, and I had to coast to the shoulder in the dark with limited control while other vehicles traveled at high speed. During the second incident, two children were in the vehicle. Both events created a serious risk of a collision or injury. The failure involves the primary propulsion system. After the first incident, the dealer replaced the engine and performed recall-related updates. Months later, the replacement engine failed in the same way. The dealer inspected the vehicle after each incident, confirmed the failures, and is replacing the engine again. The issue has therefore been reproduced and verified by the service center. There were no warning lights, messages, noises, or drivability symptoms before either failure. The engine stalled suddenly both times. A separate exterior trim piece, previously repaired under a recall, also detached while driving, adding an additional hazard. Both engine failures and the sudden loss of lighting and power created a clear and immediate safety risk to occupants and surrounding traffic. The repeated nature of the defect after a full engine replacement raises concern that the underlying issue has not been resolved.
