NHTSA Complaint #11541503 — 2004 CHEVROLET COLORADO

One day, after I turned my truck off, I noticed that my taillights and overhead cargo light remained on. Key was out, truck was off, but the lights stayed on. So for the time being, I disconnected the battery. I brought it to a mechanic, who ran the codes that came back that the rear driver turn signal was high, the rear passenger turn signal was high, and the overhead cargo light was high. He checked the entire truck for a short, replaced the taillights, replaced the fuse box, replaced the body control module, and numerous other attempts at a repair, with no success. I was without a vehicle for many months, since I can't afford the absurd prices of the current vehicle market and was hopeful it could be fixed. Reading through some other complaints/online threads, this seems like a fairly common problem with these vehicles. Electrical issues that affect my ability to use a turn signal are a huge safety concern and this needs to be addressed.
