On December 29, 2022 I stopped at the bank for 2 minute and when I got back to my truck I noticed smoke coming out from under the hood. I immediately called 911 and luckily some nice people were able to get my hood up safely and the bank provided a fire extinguisher before the fire trucks arrived. It was engulfed in flames. The fireman said it appeared the fire started in the wiring at the engine. I had a recall fixed a while back for the engine block heater so I was worried maybe they didn’t repair the recall. A week after the fire I received a 2nd recall in the mail for the same recall. Today is July 9th and my truck is still in the shop waiting on parts that have been on back order this whole time. GMC told my insurance company they were sending someone down to look at it. Never heard anything back. This could have been so bad had I been driving it when the fire started. So here I am going on 7 months without my truck all while paying $942/month. I just want something to be done to speed up the repairs that my insurance has paid. Estimate is $22,000
