In February of 2025, I took my vehicle to my mechanic for routine 100K maintenance. The pickup was running fine. After two attempts at repairs/updates using AutoZone parts that failed or were incorrect for the application, OEM parts were requested and installed. They worked great until they didn’t (at the end of May 2025)—the timing gear broke and caused catastrophic engine failure. I relied on AutoZone management promises to cover my and the mechanic’s extra costs, including a new engine. I ultimately had to order and pay for a new engine and its installation at the end of July of 2025. I have been trying since then to seek compensation from AutoZone with no success. They have copies of all invoices from myself and the mechanic along with a timeline recap of all activities and costs. I have stayed in contact with AutoZone corporate representatives that assure me that my claim is being handled. It is now September 10, 2026, and I have not received any notifications (unless I email or call them) or compensation. I cannot recommend AutoZone for their parts or their guarantee/warranty they make on their parts or their statements their representatives make.
