Truck will randomly throw codes for service 4wd and forward collision unavailable, rear cross traffic unavailable, lane departure will not work, auto high beams not work, and if parked position truck will not release Park brake making truck unable to be moved. Truck has been in and out of certified dealer 3 times and problems still occurring at random. Dealer has stated they are not able to duplicate issues and can't do anything. Issues happening pose risk while driving when codes come on making all standard safety features not to work in event of a accident. Also making truck not mobile when Park brake sets in event of accident.

The following errors were displayed: Reduce speed to 62 mph, brake system failure, Service traction control, Service ESC, Service steering column lock, Trailer brakes disabled service required. I had no brakes and had to pump them to get stopped. I was able to pull to the side of the road and shut off the engine. I called dealer and reported issue as this occurred last Tuesday. They advised to bring the vehicle in at 0800 tomorrow. I restarted the vehicle and system reset and I was able to continue. At 12:58pm, I pulled off the interstate ramp onto a county road and the engine powered down again and displayed the same errors. The brakes did not fail this time and I was able to get home.

On Tuesday we pulled out into traffic and the truck shuddered and I heard a pop. The air conditioner went out and then a plethora of warnings along with the service engine light popped up on the dash. The brakes stopped working and the truck went into a low idle almost causing the vehicle behind us to rear end us. Error messages were as follows: Brake failure do not go above 62mph, trailer brake failure, steering column needs serviced, service ecs and several others. I was able to get the vehicle back home and called for service at Green Chevy in Peoria, IL I was able to shut the vehicle off and restart it and all error codes were gone. I spoke with the dealer and took it to them. They advised it was a module issue and would reprogram it. It took 2 days and my vehicle is back.

DEF System will count miles down saying it is going to put you into limp mode while towing, when there is 3/4 plus DEF fluid in the tank. This caused me several times speed slow downs under 65 to try to make it to a safe place to add under 2 gallons to fill a 5 plus gallon tank on 70 to 80 mph highways a few times at dusk and night with limited off off travel lane access! This is telling you it will put your vehicle in limp mode! Again causing a dangerous situation! I very much feared for my well-being along a dark road with cars going 70 plus while I was trying to add DEF to a 3/4 full tank only taking around 2 gallons!!

Status: open (inferred from source dates) · Engine
On January 16, 2026, the Office of Defects Investigation (ODI) opened Recall Query RQ26001. This investigation was opened to assess the remedy effectiveness of Recall 25V-274. ODI has received complaints alleging engine failure in vehicles after the recall remedy had been completed, whether that remedy involved an oil viscosity change or a complete engine replacement. General Motors (GM) issued Recall 25V-274 to address concerns of engine failure in the L87 engines produced between March 1, 2021 and May 31, 2024. GM cited the root cause as a supplier manufacturing and quality issue. GM’s recall remedy for Recall 25V-274 consisted of two different repairs, either an oil viscosity change or an engine replacement, based on the results of the remedy inspection procedure. ODI continues to receive reports of engine failures after the completion of the recall remedy. To date, ODI has received 499 complaints alleging post-remedy engine failure in vehicles subject to Recall 25V-274, 473 of which involved an oil viscosity change and 26 a complete engine replacement. Additionally, ODI has received 191 reports of L87 engine failures in engines produced after the production period cited in Recall 25V-274. GM reported receiving 6,953 complaints of post-remedy engine failure. ODI is opening this Engineering Analysisto continue investigating complaints of post-remedy engine failure. ODI is expanding the scope of this Investigation to include engines produced after the production period cited in the recall.

The Office of Defects Investigation (ODI) has received 1,157 reports of engine bearing failure failures in the L87 6.2L engine produced by General Motors (GM). Of the 1,157 reports received, 173 are outside of the scope of recall 25V-274. These engines are installed in Model Years (MY) 2019–2024 Chevrolet Silverado 1500 and GMC Sierra 1500, and 2021-2024MY Chevrolet Suburban and Tahoe, GMC Yukon/Yukon XL, and Cadillac Escalade/Escalade ESV vehicles. The subject engine failures were investigated as part of a Preliminary Evaluation (PE25001). GM determined that these engine failures were due to multiple supplier manufacturing and quality issues. GM issued recall 25V-274 to address the supplier manufacturing and quality issues produced between March 1, 2021, and May 31, 2024. Based on the issuance of recall 25V-274, NHTSA has closed PE25001. ODI continues to receive a significant number of reports of engine failure in vehicles outside the scope of 25V-274. This presents a potential safety risk that warrants further investigation. ODI is opening this Engineering Analysis (EA) to further evaluate the scope and severity of the potential problem and to fully assess the potential safety-related issues of vehicles built outside the recall scope.

On January 16, 2025, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE25001 after receiving complaints and field reports concerning engine failures in MY2019-2024 GM’s full-size truck and SUV T1XX platform equipped with the L87 6.2L V8 engine. These complainants alleged engine bearing failures resulting in knocking and growling noises from the engine’s bottom end and in some cases more severe consequences such as broken connecting rods leading to engine damage, or engine failure. If the engine fails during vehicle operation, the vehicle will lose propulsion, increasing the risk of a crash. On April 24, 2025, GM issued recall 25V-274 to address the concern with L87 engines produced between March 1, 2021, and May 31, 2024. GM cited the root cause as a supplier manufacturing and quality issues. GM’s recall remedy will be either an oil change to an oil with a different viscosity or engine replacement depending on the results of the remedy inspection procedure. To date, ODI has received 1,157 allegations of engine bearing failure. GM submitted 55,464 reports in total, with 29,752 unique VINs. ODI continues to receive allegations of L87 engine failures which fall outside of the scope of recall 25V-274. Based on GM’s recall, ODI will close this PE.
