2008 GMC Acadia: check engine light

Filed Jul 30, 2023 · Fuel system, Transmission · AL

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.

Also my passenger side air bag keeps saying it needs to be serviced but it's never been deployed and no one has an answer for why this warning keeps coming up the stability track warning comes on as I'm driving every time after about 10 to 15 minutes and the passenger side air bag warning comes on as soon as I start the vehicle engine.

I bought my 2008 gmc acadia and not long after the check engine light came on. It was the timing chain. I had the chevy dealership replace it which was almost $3000.00. About a year and a half later it has gone out again. And I can't afford another $3000.00. Now it's just sitting. Very up set about this.

Check engine light came on due to jumped timing 3 days after we had purchased the vehicle from a dealership and a little over a year later it had jumped timing again so now I have to come up with 800 to tear down the motor so they can properly diagnose it. So I do not have the money for that so now I am stuck with a vehicle that I am paying for and cannot drive. It is sitting in my driveway as we speak. The vehicle was in the driveway and we were getting ready to leave when it happened. Both times. The dates it happened were 1/5/2018 with 137000 miles on it and the other date was 2/5/2019 and it has 152045 miles on it.

Had my transmission fail while camping in the mountains with zero cell phone service. Check engine light came on at 121,657 miles, then deteriorated until it would no longer move when pressing on the gas pedal. Taken to the local dealer told me that the transmission needs complete replacement totalling 4.5k. Gmc refused to assist me in any manner towards the bill even though this is a very known issue with this make of vehicle. There needs to be a recall on these transmissions as it is a dealer defect.

I had to have my car brought in for a check engine light. After the dealer did a full test, they narrowed it down to the gas tank area. It was a fuel module broken at the flange and also they recommended the fuel sensor to be replaced because they have been noticing a lot of vehicle coming in with the sensor going bad. The dealer also informed me that the 2008 acadia's have a design flaw in the gas tank and there is a chance in the future it may need to be replaced, but for now the tank looks really good.
