Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Dash mounted warning light indicated tail light issues. Checked the light and all the bulbs were fine but the entire tail light was not working. I then noticed the the brown wire in the connector had melted through the case and was touching other wires in the connector which caused it to short out the entire light. The brown wire has visible signs of melting. I have since found out that this is a common problem with my type Bmw and a recall has been issued. Right now my VIN number does not fall under the notice but I have no tail lights.”
