Coughlin Chevrolet of Pataskala review

My drivers side mirror is loose and rattling on bumps on

November 9, 2025
By Sendykar, James M from Pataskla, ohio

My drivers side mirror is loose and rattling on bumps on road. Was accused of wrecking my truck causing damage with no signs of damage to my mirror. I was kinda insulted by the fact my truck was never in a wreck and causing any damage. By the way my truck only has 13,170 miles on it. Under warranty. I get the feeling that the dealership doesn?t want to take care of warranty issues.
