Complaint Summary

ENGINE AND ENGINE COOLING

Owner Narrative

The contact owns a 2021 Chevrolet Tahoe. The contact stated that while driving approximately 45 MPH, the check engine warning light illuminated, and the message “Reduced Acceleration - Drive Safely” was displayed. The vehicle then started shaking abnormally. The contact pulled into a nearby parking lot, turned off the vehicle, and waited for a while before restarting the vehicle. After restarting the vehicle, the warning lights remained illuminated, and the vehicle continued to shake abnormally. The vehicle was taken to Auto Zone, where a certified mechanic diagnosed the vehicle and determined that there was a bent rod inside the engine. The vehicle was not repaired. The vehicle was taken to the dealer, who confirmed the diagnostic result and that the failure was causing additional damage to the crankshaft. The dealer determined that there was a misfire in the engine and that the valve lifter was malfunctioning. The contact was informed that the lifter and the camshaft needed to be replaced, and the engine needed to be repaired. The vehicle was not repaired. The contact researched and became aware of NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling); however, the VIN was not included. The manufacturer was informed of the failure and confirmed that the VIN was not included in the recall. The contact was referred to the dealer to inquire about a Goodwill Repair for which the contact could be reimbursed if the VIN was later added to the recall. The manufacturer referred the contact to the NHTSA Hotline to report the failure. The failure mileage was approximately 100,000.
