The motor that opens and closes the trunk has burned out twice already. there is something in the system that will make the motor get stuck and burn out until it stops working. we have tried replacing it twice, and the same thing happens. our trunk won't close now and it remains open and unlocked.
Power lift gate malfunction. the power lift gate struts failed which caused the lift gate to open only 1/3 of the way before closing unexpectedly. sometime it would open all the away, the power arm would then disengage causing it to unexpectedly close. sometime it would close as "dead weight" with enough force to seriously injure an adult and possible kill a child or pet. when i took my vehicle to the dealer, i was told the struts needed to be replaced. i have had this vehicle for two years. i purchased it as certified used. i was charged $415 for the repair. unfair as this vehicle is only four years old! further, i authorized the work at approximately 4:45pm, my vehicle was complete by 5:30pm the same day. i was charged two hours labor at $125 per hour. how is that fair? my vehicle was stationary when this happened, repeatedly. i look forward to your response. other than this, i love my gmc!!!!!
