Example complaints

Electrical system: “I clicked my 4-way flasher button while dropping my son off at the train station and when I came back it was difficult to press the button back down. After that, the operation of my emergency flashers was intermittent and eventually my rear brakes lights started working only intermittently as well. Now the brake lights do not work and my GM dealer says it will cost more than $500 to replace the whole wiring harness. This is the second failure of this type on this same suburban.”

Brakes: “The contact owns a 1999 Gmc suburban. The contact stated that the brakes were wearing prematurely. The vehicle was towed to the dealer, who stated that the brake lines, hardware, brake cylinder and calipers needed to be repaired. The manufacturer was made aware of the failure. The vehicle was repaired. The failure mileage was 99,000 and the current mileage was 137,960. Also, the A/C was repaired several times, as it was blowing out hot air, the rear passenger door was inoperative, the starter was replaced, the radiator was leaking. Updated 07/30/14”

The vehicle was taken to an independent mechanic where it was diagnosed that the field fractured and caused oil to seep into the engine. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was 126,000.”

Air bags: “Airbag light is on. Needs new module and the part is currently unavailable from Gmc. Repair shop will not guarantee work on installation of a third party part. I have spoken extensively with Gmc corporate and they continue to delegate this issue to the dealership level. Imo, the dealership (thorson motor center, pasadena, ca) has done all they can by ordering the part for me. If the part is unavailable, that is not the dealership's fault. Further, there is no estimated time of arrival even though the order has been expedited. …”
