davesautocenter/TikTokA Chevrolet Silverado owner faced a staggering $15,000 repair bill after a dealership claimed his truck needed a new engine and transmission. However, a second opinion revealed a different problem with a much lower estimate.According to a TikTok video shared by Dave's Auto Shop, the owner of the 2020 Silverado, which had fewer than 90,000 miles, initially visited a GMC dealership after hearing an odd noise coming from his truck's engine.The dealership recommended replacing the engine and transmission for $15,000. It later suggested replacing the spark plugs and wires as well for approximately $800.davesautocenter/TikTokStill concerned, the owner took his truck to Dave's Auto Shop and they documented the inspection in the TikTok video.The mechanics discovered that the truck had a collapsed engine lifter, a part that helps control the opening and closing of the engine's valves.The shop estimated that repairs would cost approximately $9,000 — which was $6,000 less than the dealership's original quote.The mechanics also questioned whether the dealership had actually replaced the spark plugs and wires because the components on the truck appeared worn.davesautocenter/TikTokHowever, Dave — the owner of Dave's Auto Shop — refused to name the dealership that initially inspected the truck."Listen, this is why I don't do that. I'm just the investigator. I'm not the judge," he explained in the clip. "I don't get the other side of the story. The shops don't talk to me and give me their side of the story.""I get an email or an invoice from a customer, and I'm looking at it. That's all I have," Dave added. "So, it would be unethical of me to throw somebody under the bus without them telling their side of the story."Read More From First for AutosCalifornia Drivers Could Face $238 Fine for Flashing Headlights to Warn Others About PolicePhiladelphia Named Worst U.S. City for Drivers as New Study Reveals the Best Places to DriveAlleged Scammer Booted Random Vehicles To Demand Payment, Authorities SayThis story Chevy Silverado Owner Receives $15K Repair Quote From Dealership, $9K From Second Mechanic first appeared on First for Autos.
