I was driving down [XXX] in LaPuente and every light on my dash lit up and I attempted to Exit freeway and my brakes would not work so I waited for car to slow down and luckily I was near by the Puente hills Chevrolet dealer. Also my steering wheel was very lose and it felt that I couldn’t steer well. I pulled into dealership and had to push my brakes all the way to the floor board just for Tahoe to stop. Dealer said that there was various communication codes which they said vehicle would have to stay due to safety issues. My vehicle has been at dealer for 3 days so far INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On multiple occasions my vehicle brakes with no warning. So much so I can hear the tires screech ever time. I brought to a dealership and they told me they can’t find the issue and no fault codes. This is understandable due to the fact that it doesn’t always happen. It’ll go so times a full day without happening. It mostly happens on the highway but happened today (24-July-2025) around 17:30. So needless to say this is a huge issue especially seeing I have three small children. Thank you so much for your time in this matter and I hope this finds you well.

1st incident- Engine had a bad lifter and cam shaft with 46,000miles. When this happened I was going through a railroad crossing, if the failure was bad enough and locked the engine up I would have been stuck on the tracks with my family. This issue could cause the motor to lock up if the lifter or cam shaft had a more serious failure. Dealer confirmed the lifter and cam shaft were bad and replaced. the engine had a vibration 2 weeks before the failure but the dealership could not identify or duplicate the issue. Vehicle was in the shop for 35 days to repair. 2nd incident- Parking brake and brake system locked up and would not release until the vehicle was reset. Scheduled vehicle to be towed in and the brakes locked up again while loading the vehicle to tow. Dealer is still troubleshooting the issue after 5 days. Errors on screen "Forward Collision System unavailable, Brake system failure 43mph top speed, Service steering column lock, service traction control, Service ESC, Service Brake Pad Monitor" If this happened while on the highway it had the chance to cause a serious wreck.

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.
