What 2008 GMC Acadia owners say
Transmission & drivetrain all 279 →
Check engine light came on for the TCM. Car has had issues shifting (very rough shifting) and the manual shift option does not work. Was told the TCM had to be replaced. Attempt was made to replace it with a refurbished TCM but that couldn't be programmed to the car. Was then told I would have to buy a brand new one, which is very expensive, and that there was no guarantee that would fix the problem. Car can not be driven over 20mph without risking burning up the transmission. Car also jerks forward very hard when trying to gently accelerate.
Transmission failed, transmission slipped out of gear, transmission stuck in first gear, GM approved a 2013 safety recall for this vehicle, the transmission failed in 2017, the transmission was repaired and the entire engine has been replaced twice. The transmission is failing again because it is a product defect that is dangerous. GM has refused to repair or replace the vehicle and the autonation has refused to repair or replace the vehicle. GM and autonation have sold a dangerous used car with a fraudulent intent. GM and autonation have ratified the intentional fraud. The car needs to be replaced immediately because it is still dangerous to drive and the transmission is currently failing again.
