2008 GMC Acadia: jerking or lurching

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.

The headlights don't work even after replacing. It rains in the vehicle from the sunroof. The gas tank isn't registering even after fixing it. So the engine doesn't know how much to put out etc etc and it makes the car jerk horribly. This vehicle is a fire hazard due to raining inside on everything upfront. I have kids I pray nothing happens!!

When I purchased the vehicle in less than an hour the check engine light, airbag light , tire pressure sensor popped on. The car would have a slow take off and shake as you accelerate on the city street. When I drive the freeway the car will hesitate and take 15 seconds before it switch gears to catch up to speed and jerk. The service airbag,service tire monitor system, service stabilitrak, service traction control alert messages are on the message console.

While accelerating I've noticed my vehicle has some type of wave plate issue but it seems common for these vehicles. It jerks and shakes and it's not safe.

What's not wrong with this car?? I bought it used with an extended warranty. After a year everything went downhill. It has been in and out the gmc service at lease 3 times a year. I don't even know where to start. The airbag light is on but it isn't covered under the airbag recall. What about safety? There has been a check stability trac and traction lights on as well on several occasions. When those lights come on the vehicle decelerated while driving across the kentucky bridge which almost caused a 12 car pile up. In addition, it also skips gears. When trying to speed up it jerks into the next gear like a hiccup. The dealership stated these problems were electric and wear covered under my extended warranty. I suggested that maybe the transmission was bad. However, they stated otherwise. Literally, 4 months later the transmission is out. But what a surprise no longer under warranty. Now I'm looking at a $5,000 bill. The service department stated that it is transmission failure due to an electric issue (out of my control). There is nothing that I could have done to prevent it from happening. But after talking to gm they, basically explained that they don't stand by their product after 100,000 and that they can't prove that the issues are actually manufacturers defect. I strongly disagree as there are hundreds of people experiencing the same hardships as me with the 2008 vehicle. On [xxx], for gmc acadia, 2008 is the worst year with the most complaints for transmission failure. How aren't these already recalled by now? They are nothing but junk! Not work anything. Even a gmc service rep. Said these were the worse year and get them in the shop all the time. Why won't gmc just isssue a recall and take them off the market. I have all the proof of regular maintenance and service receipts.

2008 gmc acadia with just over 30,000 miles started jerking a couple days ago when gears would change from first to second. I took it to my mechanic today and what do you know - I need a new transmission. I can't believe that gmc has done nothing about this after reading all of the complaints. A $3000 repair if I'm lucky. My car looks like new and is hardly driven - and the transmission goes out?? Crazy

Vehicle lurches when going from 10mph to 20mph was going downhill would no longer accelerate once I was at 40-45 MPH it revs up to 4 and nothing had to coast downhill turn into a parking lot and stop the car. Took it to the dealer who sold it to me and he was able to replicate the same issue under similar circumstances. The dealership will look at it but I bought it used for my family at 99,950 miles 8 days ago

Coming home from out of town I noticed my acadia started jerking, yet there was no check engine light well nothing telling me that something was wrong planned to take it to the mechanic the next day, when I got up the next day to take it in it would not go in reverse and would only drive less than 20 MPH suddenly the check engine light came on being my only source of transportation I towed it to a mechanic shop, the mechanic told me that it was the transmission but he could not offer a reconstructed transmission because the 2008 transmissions came out faulty that I would have to purchase a new one and that gmc knew about this so they put out in the market renews and improve ones..... Total cost 3,417.00 not to mention interest on it due to having to borrow the money since I didn't have it. My question why wouldn't gmc put out a recall instead of improving it for the owners to purchase.

My family and I were driving out of town and then started to feel the car jerk at times and then out of no were it said stability traction control off and reduced power of engine and then engine started to make a terrible noise and shaking like it was going to give out. I could barely pull over. I have taken it several times in to get checked for the stability and they can never find anything wrong and they say its one thing and all I seem to do is pay for something that doesn't need to be fixed. This same issue has happened 3 times since then.

The transmission had been hard shifting from 3rd to 4th for about 200 miles. At 25 MPH while turning through a very busy intersection the engine revved shifted through what felt like every gear, the car lost acceleration power; going from 25 MPH to 10mph. Parked the vehicle. Restarted to find that only first and second gears worked and the check engine light illuminated. During the 200 previous miles of concern; I had heard a faint whine during acceleration. The first time any trouble occurred the vehicle was stopped behind a school bus loading and while I applied the brake (still completely stopped) the car lurched forward. I immediately shifted to neutral, not wanting to rear end the school bus.
