Brought my truck in for a routine oil change—nothing

Reviewed by Norm from Kansas ILJune 13, 2025

Brought my truck in for a routine oil change—nothing special. When I got it back, I noticed a trim piece beneath the steering column had been left off. Not a huge deal, mistakes happen. I brought it back and politely pointed it out. The response? “I don’t have anyone to look at it. Bring it back another time.” So I did. I rearranged my schedule and took time off work to come back. This time, I was told that GM wouldn’t approve fixing it unless the part was broken. Not missing. Not reinstalled incorrectly. Just broken. Apparently, restoring something to the condition it was in before their techs touched it is beyond their responsibility. Out of curiosity, I called another dealership. They had no issue addressing the problem—because they understand how customer service is supposed to work. That leaves me with three possible conclusions about the person I dealt with: He’s lazy and unwilling to take ownership. He’s uninformed and unqualified. Or he’s lying to customers to avoid doing his job. None of these options instill confidence. All of them guarantee I won’t be back.
