NHTSA Complaint #11670042 — 2014 CHEVROLET SILVERADO 1500

I believe Ray Chevrolet (Antioch, IL & Fox Lake, IL) are negligent in that they did not apply treatment as described in TSB #14002A while they had custody of our 2014 Chevy Silverado. The vehicle has been maintained mostly by the Fox Lake, IL location, but was purchased at the Antioch, IL location new. TSB #14002a clearly states that before the vehicle is released to the customer that the treatment should be applied. The vehicle has been maintained mostly at the Ray Chevrolet Fox Lake, Il 60020 dealership location over the past 10 or 11 years. Not once did any mechanic or service advisor mention TSB #14002A nor the deteriorating state of the truck's frame. This became a safety issue as described below. I was traveling on [XXX] which is under construction. I hit a bump and temporarily lost control of the vehicle. I also talked to my wife who also drives the vehicle. She said it sounded like an empty gas can was rolling around in the truck's bed. I took the vehicle into Ray Chevrolet at the Fox Lake, Il 60020 location and talked to a service advisor and told him about temporarily losing control of the vehicle and what my wife said about the loud bangs. We received notification from the Ray Chevrolet Fox Lake, Il dealership's service center via DM with a video attached. I watched the video and called the service advisor. The service advisor told me that the repair wasn't worth doing because it was more expensive to do than what the truck was worth. The same service advisor told my wife they would not do the repair which is replacing the truck's frame at an estimated cost of $15,000.00. He also told my wife that the truck is unsafe to drive. Because these service centers did not apply treatment either when the truck was purchased new or during the 10 or so years it's been serviced by these service centers, I believe these service centers have been negligent in their responsibilities to me and my wife. The truck has 106,044 miles. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (F
