NHTSA Complaint #11650320 — 2024 GMC CANYON

Heat shield over drive train not installed properly. While driving since purchased I’d hear a metal reverberation / clunking sound that seemed to be under the truck. I even had it in for oil change service w/ dealer and no mention of finding anything. On Sat 3/15/2025 I took it back to dealer with the heat shield that was torn from the undercarriage over the drive train, the service person said it did not to appear to have been fastened at the factory before delivery to dealer/me. They were going to re-install it, however it was damaged; and I told them that was not acceptable to put a broken part back on the truck. I still don’t know what other damage has occurred to the vehicle due to the rubbing/clanking around while driving the 12,000 miles I have on it. They told me it was safe to drive and just come back when they get the part in. I have photos and videos; the dealer took the damaged heat shield from me and I don’t know what they did with it. Risk level to other drivers is the heat shield could have flown off truck while driving; to me inside the vehicle could have obstructed drive train and caused damage/accident, and other damage I’m still not aware of. Yes, dealer advised: Harnish GMC Puyallup, WA 253-840-6300 No fix yet. No warnings in vehicle or on any electronic displays. I noticed the sound right away on purchase but couldn’t identify it until it “got so bad” I went under the truck to look, and found it separated and dragging on the drive train.
