What Owners Say
""warning light came on telling tech we had a potentail failing coolant pump, to fix the pump they had to update software for $300, only the could they change the pump. Software did nothing, so I took vehicle to someone other than dealer to assess the vehicle. coolant pump has been replaced, problem solved. I simply don't trust dealers or GM any longer, I believe they bake issues into their vehicles to drive up revenue""
Anonymous, PA (2021 Chevrolet Tahoe Z71 6.2-L V8)""Fuel pump control module failed, car couldnt be turned on. Because we couldnt turn it on, we were unable to shift to neutral to tow.""
