NHTSA Complaint #11695927 — 2013 CHEVROLET EQUINOX

I am submitting this complaint regarding an ongoing and serious safety-related timing chain issue with my 2013 Chevrolet Equinox LT. The timing chain loses tension intermittently, which places the vehicle at immediate risk of significant engine damage, stalling, or complete loss of power during operation. This issue compromises the vehicle’s ability to operate safely in traffic. A sudden failure of the timing chain system can result in abrupt engine shutdown, without any warning lights or diagnostic codes to alert the driver. This creates a dangerous situation, particularly when traveling at highway speeds, merging into traffic, or navigating intersections. The timing chain defect in this model appears to be a known and recurring problem among owners of similar GM engines, and there is evidence suggesting design flaws contributing to premature wear and tension problems. However, this vehicle has not been included in prior recalls addressing similar timing chain failures. I rely on this vehicle for essential travel and live on SSDI, which limits my ability to cover repeated high-cost repairs for what appears to be a manufacturer-related safety defect. The risk of sudden engine failure with no prior indication is unacceptable and warrants further investigation. I respectfully request NHTSA review this concern as a potential recall safety issue, given the clear risk of power loss and danger to both myself and other drivers on the road.
