Jul 20, 2026

While driving enroute to a concert in [XXX]., in the passing lane on [XXX] around [XXX] & just before exit 22(mile marker 21) during rush hour on 7-23 at 5.09pm, my truck abruptly lost power and shut off! It would not start, I could not engage "N" from "P" to attempt to push my truck to the far left side of the highway. This was a "VERY DANGEROUS" situation as I could have been rear ended or much worse! I immediately called SOS/ON STAR for assistance. In the meantime, a police officer and state troopers showed up to divert the traffic around my truck. Eventually, a "HERO" vehicle showed up and at the direction of the police, my truck was "DRAGGED" from the passing lane to the emergency lane. As for getting a tow truck, 1 finally showed up after 5+ hours. I found out the you all have a contract with "AAA", which is the worse when it comes to getting any assistance. I was towed back to [XXX] to South Town GMC dealership & arrived at 11.25pm. It was only the next morning that I received an email from OnStar dated 7-23 at 5.07pm, with an "Advance Diagnostics" advising of a critical issue with the engine & transmission. The code was: P129F, which is the fuel pump and/or module. My truck now sits at the dealership with a dead battery, waiting for them to address. I have heard that there are issues and recalls in certain vehicles with this similar issue. I do have "extended warranty" protection thru Ally that I bought. However, the shock is finding out that the only way to get it into "N" is a special dealer tool that goes into the transmission under my truck! Are you SERIOUS??????? To have no ability to put my truck into "N" is not only unacceptable, but extremely dangerous. Especially with what happened to me & my family. At this point, I am at the mercy of my dealership to find the time to address this issue. Until then, I have no transportation & very upset with the stress of all that happened!

On November 20, 2025, my 2022 GMC Sierra 1500 AT4 equipped with the 3.0L Duramax diesel engine began experiencing intermittent engine overheating conditions. Concerned about a potential safety issue, I contacted a GMC dealership and was advised that because no diagnostic trouble codes were present, there was nothing to diagnose or repair and that I should continue driving the vehicle. Over the following months, the overheating condition continued intermittently. On May 24, 2026, while driving on the highway, the vehicle suddenly overheated, displayed fault code P1098, and entered reduced power ("limp mode"). The vehicle lost normal performance and acceleration while traveling in traffic. This created a significant safety hazard because the vehicle was unable to maintain normal highway speeds, increasing the risk of a rear-end collision or other traffic accident. The loss of power occurred while driving and without sufficient warning, leaving the vehicle unable to safely perform as expected in highway traffic. After researching this issue, I found numerous reports from other GMC and Chevrolet owners describing similar overheating, coolant control valve, thermal management system, and P1098-related failures. Many owners report symptoms involving engine overheating, reduced engine power, and limp mode operation while driving. I am concerned that this may indicate a broader defect involving the vehicle's cooling system and thermal management components. The vehicle exhibited overheating symptoms for approximately six months before the final failure occurred. Additionally, I understand that certain GM vehicles have been subject to service actions involving coolant control valves and thermal management system components. Given the similarity of symptoms, I am concerned that the overheating condition reported in November 2025 may be related to the same type of failure mechanism, yet my vehicle has not been included in any recall or special coverage program.

May 24, 2026

I was driving to work when my vehicle’s check engine light illuminated, accompanied by a warning message stating, “Low oil pressure—turn vehicle off.” I immediately followed this instruction and shut the vehicle off. When I attempted to restart it, the engine cranked repeatedly before finally starting, but the same warning message reappeared, prompting me to turn it off again. A few months prior, I had the vehicle inspected at the dealership, where I was informed that it passed the 6.2L engine national recall inspection. On April 9, 2026, the vehicle was towed to the dealership for further evaluation. On April 10, I was contacted and informed that technicians could hear a metallic noise coming from the engine. However, they stated that the readings from the PICO test were not high enough to meet the criteria for engine replacement. The dealership recommended replacing the camshaft position sensor but could not confirm whether this repair would resolve the issue. They also indicated that I would be responsible for all associated costs. Despite the presence of concerning symptoms, including abnormal engine noise and repeated warning messages, I was advised that General Motors would not approve an engine replacement unless the engine either completely seizes or fails both required diagnostic tests. At this time, my vehicle has only failed one of the two tests. As a result, I have been left without a reliable and safe vehicle, which is significantly impacting my ability to commute to work. This situation places me at risk of financial hardship and potential job loss. I am seeking a resolution that ensures my vehicle is properly diagnosed and repaired so that it is safe to operate.

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.

While driving on the road the vehicle started sputtering and stalled! We pulled to the side of the road and tried to start the car but it rolled and would not start. We called a a mechanic who had it towed and found out that the fuel pump and the fuel control board had failed. Both have been replaced and the truck seems to be working again. Heard several other persons had this issue with their GCM Sierra Elevation so we wanted to report since there is currently no recall. Luckily the traffic was not going that fast or we could have had an accident and been seriously injured.

The contact owns a 2022 GMC Sierra 1500. The contact received notification of NHTSA Campaign Number: 25V274000 (ENGINE AND ENGINE COOLING). The contact had parked the vehicle in a parking space when the engine seized. No warning lights illuminated. The vehicle failed to restart and was towed to the dealer, where it was diagnosed and determined that the fuel system control module had failed. The contact was informed that the part to do the recall repair was not yet available. The vehicle remained at the dealer unrepaired. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was not made aware of the issue. The failure mileage was approximately 90,000.

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.

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.

My truck went into "limp" mode and had very little power. It was towed to the dealership where they diagnosed the issue as a bad solenoid causing the engine misfires. The solenoid was replaced, but the issue was not fixed. Now the dealership is stating the engine has bent lifters and the repairs will not be covered under the ongoing massive engine recall. The vehicle had the pico test on 9/17 and it "passed", but less than 3k miles later and the engine failed. This is a clear safety issue and well known by NHTSA and GM. Now I'm negotiating with the dealership to cover repairs and my truck has been gone nearly a month.

My truck is under the national recall from GMC for the 6.2L engine problems. I even received the recall notice from GMC stating this. This truck has been in and out of the shop for engine problems things I took delivery of it in 2022. The latest was in April of 2025 and while it was in the repair service at the dealership, the national recall came out. During that time the dealership tried to tell me the problem was with my exhaust system so I was not covered under the recall. I knew they were not being truthful so I refused to take possession of the truck as I new it had all the symptoms that GMC was describing in my recall notice. My truck sat at the dealership for almost 5 months and last week they force me to take possession of my truck my taking back my "loaner vehicle". They stated "my truck passed the required inspection", which I knew they were being dishonest, but was forced to take the truck back anyway. Three days after taking possession I was on the interstate doing 60 mph and the engine totally seized up and almost caused an accident from the vehicles behind me running into me because of the sudden decrease in speed. I was able to safely pull over and had to get towed back to the dealership. This incident is beyond just a engine recall now because they new my truck was not safe to drive and forced me to take back my truck. Im just thankful I was driving and not my wife, or having my two grandchildren in the truck with me. To make mtters worse in this scenerio, this truck is actually my replacement truck because my 2021 truck had to be taken back per the Lemon Law in 2022, so this will now be truck #2 being Lemon Law and my original truck loan isnt even paid off. I have all of the various engine repair paperwork on this truck dating back to 2022.

My daughter and I drove to town to run some errands, we live twenty-three minutes away and take the freeway. Speed limit on that specific section of the freeway (I80) is 80mph. As I was taking the on-ramp to enter traffic, My GMC started shifted very hard and losing power. The vehicle was sputtering and making strange sounds. I was unable to exceed 60mph due to excessive vibrations/shaking the vehicle. Steering was starting to be difficult at the same time I noticed Oil Pressure Gauge slowly dropping on instrument panel below 25psi. I had to pull over immediately. oil pressure remained lower than normal, verified Oil was filled to manufactures specifications (changed June 30, 2025). Returned the vehicle to my place of residence as safe and slow as I possibly could and parked it as it is a major safety concern.

Unloaded my Denali at huge loss with 30,000 miles because gm wouldn’t fix recall after many times in shop, broke down on freeway, and need to travel to Canada on business. Canada won’t allow vehicles with open safety recalls to enter country even though im pretty sure engine was MADE in Canada. Gm corporate office told me there’s nothing they can do. While in shop for 4 days of testing i watched vehicle on app, never started, moved, just put out back for 4 days then told absolutely nothing. Just wanted fair trade in for diesel. Truck looked identical to brand new on lot, 10/10 except engine recall. Gm promised to reimburse rental fees when broke down a week or so, submitted documents to Gm, nothing recieved. Bought ram instead for obvious reasons. Is there a lemon law, class action, agency etc that can help compensate for losses? The public should be warned!

Truck has had multiple "service emmision system" errors which can leave the driver stranded and left in traffic as the truck goes into limp mode and won't maintain speed with traffic flow. There are electrical glitches and issues with the circuits and heating elements themselves and in the pump... as soon as there is an error in the system... which has happened 3 times now in 104k miles (~80, 103k and 104k)... the truck is rendered useless and stuck in traffic. Emmisions system needs to be covered for the life of the vehicle if it is going to have non stop issues.

“Faulty fuel pump driver module” part Not available for inspection. Repaired at dealership and they kept the part. While driving 75 mph on the interstate during high traffic time my GMC Sierra 3.0 diesel truck engine shut completely down, not just once but on several occasions putting myself and three other in a life safety situation due to the traffic around us at the time. I had to navigate the truck through traffic and off the road. Once there the vehicle was turned off allowed to sit for a few minutes and restarted. The vehicle would restart and we continued only to have this scenario repeated again several times. Faulty fuel module was diagnosed by mechanic at dealership and replaced. Part was not inspected by no one to my knowledge except the mechanic. There was no prior warnings before this incident happened. After the incident the engine light came on with a message that stated check ESC.

There is an occasional burning rubber smell(weekly and daily) coming into the cabin of the truck from the Duramax engine/exhaust. The dealer was notified and they informed me from their bulletins on the matter, that they believe it is from a "wax" on the vehicle exhaust system when heated up. They informed me that their is no remedy or fix at this time. The smell and air quality that me and my family are breathing I believe is unhealthy and possibly toxic. I would like the GM to replace these components causing the issue.
