Diagnostic: Video Processing Module includes replacement and reprogramming and calibrations Diagnostics when referred to in an automotive sense is the various testing done on the automobile to ensure safety and proper engine functioning. These tests are done with different sensors, computers and machines to establish a “cause and effect” relationship between what is working and what is not working with the automobile. The forms of diagnostics can range from brakes, to air conditioning, to suspension and many more.

Subject: Urgent Safety Concern – Widespread Failure and Nationwide Backorder of OnStar Module (GM Part No. 86803964) Dear NHTSA, I am writing to formally raise a serious concern regarding a widespread and well-documented failure of the OnStar module (GM Part No. 86803964) in 2023 GMC Sierra vehicles and potentially other GM models. I own a 2023 GMC Sierra equipped with this module, which has failed, rendering my vehicle’s entire instrument cluster completely inoperative. All screens, including the digital gauges and essential driver information displays, are blacked out, leaving the vehicle in an unsafe and non-drivable condition. After contacting numerous GM dealerships across the country, I have discovered that this part is on national backorder, with over 4,000 units reportedly pending. I have also learned that the part number has been superseded multiple times, suggesting an ongoing and unresolved issue. To make matters worse, Specmo is reported to be the sole refurbisher and distributor of replacement modules, further limiting availability and delaying resolution. This issue directly affects vehicle operability and driver safety. The inability to access critical information such as speed, fuel level, warning indicators, and system diagnostics significantly increases the risk of accidents and vehicle malfunctions. Given the scale of this issue and its impact on public safety, I urge General Motors, relevant regulatory bodies, and consumer safety agencies to investigate this matter thoroughly. A recall, expedited solution, or broader communication to affected customers appears necessary at this stage.

I just left the gas station from getting a beverage, I got onto the interstate and had gone roughly about 3 miles before setting super cruise a few minutes after that the interstate takes a turn to the left with an exit on the right. Slightly right as I was just getting into the turn my engine shutoff and or died making my truck uncontrollable causing me to drive off the interstate into some small trees between the exit and the interstate. I was not injured and no other vehicles were involved. My truck is currently at the insurances storage yard and they care claiming it to be totaled. I have contacted GM and filled a claim however they are saying they aren’t responsible because the insurance company has my truck. I feel like regardless of who has my vehicle the manufacturer should be responsible if the issue pertains to a specific recall that has already been issued 2 weeks after my accident. I have contacted several lawyers but since I wasn’t injured they aren’t interested in taking my case. My concern is I’m getting screwed over financially because my truck was only a year old and now my insurance is going to be crazy expensive when the manufacturer should be the one taking responsibility for this and not myself.

Engine has seized twice, completely shutting down without electrical power or brakes. The vehicle also shut down in an intersection (no power, brakes, flashers). I was able to pull to the side on the 2 engine seizures but not during the electrical shutdown at the intersection in the turn lane. The engine was replaced the first time by Quality GMC in Albuquerque, NM. The 2nd engine is being replaced by Diamond GMC in Palmdale, CA. Warning lamps on the 1st engine seizure was tire pressure warning. The electrical shutdown was forward collision warning, emergency braking, etc. The 2nd engine seizure said something about engine needed to be restarted.

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.
