Consumer Description

On [XXX] driving to Denver the 52,000 mile yukon started making a clicking sound when accelerating on the interstate. Traction control light came on as well as the check engine light. Low power was noticed and we immediately pulled over as it sounded like it was going to blow up. Towed the vehicle 145 miles where we bought it and the shop confirmed the lifters and 5th cylinder are the issue and that the cams could be damaged. Recommend replacing each side. The car is basically new and under the 60K drive train warranty but about 100 days past the 5 year mark. Terrible timing. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
