2023 Chevrolet Silverado 1500

The Office of Defects Investigation (ODI) has received 36 Vehicle Owner Questionnaires (VOQs) alleging engine failure in vehicles subject to Recall 25V274. In each VOQ, the engine had the recall remedy completed prior to the reported failure incident. Recall 25V-274 addresses vehicles equipped with a L87 6.2L V8 gas engine that experienced engine damage or failure. Recall 25V-274’s remedy includes an engine inspection.  Based on the results of the inspection the vehicle will receive an oil change to a higher viscosity oil or an engine replacement.  The complaints received allege failures of both remedies. ODI is opening this Recall Query (RQ) to assess the adequacy of the remedy for Recall 25V-274. To review the ODI reports cited in the Opening Resume ODI Report Identification Number document, go to NHTSA.gov.

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. To review the ODI reports cited in the Opening Resume ODI Report Identification Number document, go to NHTSA.gov.

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. NHTSA will continue to investigate complaints of engine failure outside the scope of recall 25V-274 as part ofEngineering Analysis (EA25007). To review the ODI reports cited in the Closing Resume ODI Report Identification Number document, go to NHTSA.gov.

Multiple times the truck has stopped running while driving. Once one the highway, once in an intersection, another time in a parking lot. It has not started when I have tried to turn it on. All the times I have called AAA. They have checked the battery and there is no battery issue. Twice AAA has come out, once the police have come and sat behind the truck to keep me safe. After about 10 minutes of the sitting with the truck off I can restart it and drive. Upon research, other Chevy trucks of similar age have a recall for a failed fuel pump module. This is the issue. If it is a known issue, and causing a dangerous situation it should be recalled on all trims of Chevy trucks. I will be getting this fixed, but don’t feel I should incur the $1,000 expense for a known defect.

Was making a left turn with a left turn street light green for me to turn across an intersection. Pickup stalled in the middle of the intersection and would not start. With the help of another person we manually pushed the pickup out of the intersection and onto another side street. I received an email at that exact time from General Motors showing a code of P129F which is the Fuel Pump Power Control Module. I am a [XXX] man stranded in 90 degree heat with no AC or shade to get under. My safety was put at risk in the above instance but more so if I had been entering IH 10 into traffic traveling 70MPH and my truck had just stopped running without any warning. This is a known problem as described in GM Service Bulletin 24-NA-139 with both the NHTSA and DOT. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

a week ago I was backing up and this truck is supposed to be equipped with a "REAR CROSS TRAFFIC BRAKINGF – When in Reverse, the system warns of detected cross-traffic approaching in either direction and provides alerts and hard emergency braking to help reduce the severity or help avoid collisions at very low speeds", I backed into another vehicle that was parked behind me. I did not receive any warnings and the automatic braking did not activate. I was fortunate that I was going slow and only damaged the other drivers door and my tailgate and bumper.

When driving normally OR pulling a camper (same day), power steering seems to "stick" as I exit either a moderate RH or LH corner. I must apply extra effort to the steering wheel to straighten out, and that invariably leads to an over-correction and departure into either the shoulder or the opposite lane. Problem is not sensitive to speed or weather conditions. The symptoms are not necessarily worse when pulling a camper, but the consequences are much more drastic and losing control of the vehicle feels much more imminent than when driving just the truck. Because the problem comes and goes so quickly, I can be applying force to straighten the wheel when suddenly, no force is required and the truck veers either left or right. I see no warning lights, nor do I see any messages displayed. I have not yet had the opportunity to get the truck to a mechanic. I'm not confident that I can safely drive to a repair facility, as the steering is so unpredictable.

The left front turn signal becomes inoperable at times. The foreword collision indicator warning will come on unprovoked at times. Both conditions correct when you cycle the ignition switch. I consider the turn signal problem a safety issue because it happens with no warning and oncoming traffic may not know I am turning left or changing lanes. When the foreword indicator appears, I doubt the system is operable.

General Motors has decided to conduct a Voluntary Emission Recall. Certain vehicles may have a condition which can cause the fuel pump power control module to fail. If this were to occur, fuel flow to the engine could be interrupted. Dealers will replace the fuel pump power control module.

Certain vehicles may have a condition in which the Engine Control Module (ECM) does not sufficiently control fuel injector flow rate under certain driving conditions. Dealers are to reprogram the ECM.

Certain vehicles listed above may have a condition in which the vehicle may shift out of park without key fob inside vehicle while in "Protected Idle" Mode. Dealers will update the BCM software. Owners who have accepted applicable terms and conditions will have the opportunity to accept these software changes using wireless over-the-air (OTA) technology without having to bring their vehicle to a dealership. Alternatively, owners may have their vehicle serviced at a GM dealer to receive these software updates.

This Preliminary information communicates an issue with the SES MIL and DTC P062B and engineering is currently investigating.

This PI Communicates information to ensure Memory Recall is enabled to ensure memory mirrors return to set position after curbview assist is used.

This Preliminary information communicates to the technician on the a potential cause for Buzz/rattle/vibration/ from the passenger side when the vehicle is under light load, with a 3.0L LZ0 Engine. It also addresses the potential for a slow/no crank or not charging.
