Overdrive function faulty in transmission. During cold weather stability trac kicks in and will not regain power even though there is no bad road conditions (such as snow, ice, or rain) it seems to activate when the weather is cold. It barley moves inhibiting normal traffic flow which is very dangerous. Fixed moon roof leaks causing the electrical components to malfunction and rain water drips on passengers and thoroughly soaks the carpets leaving a mildew smell.

Tl* the contact owns a 2007 gmc acadia. The contact stated that the vehicle failed to accelerate when the accelerator pedal was applied numerous times. In addition, the transmission failed to function properly when shifting and various warning indicators illuminated. Within a week of owning the vehicle, it was taken to the dealer (shoreline auto group inc, 2275 n state rd, ionia, mi 48846, (616) 523-6882). The dealer kept the vehicle for over a month due to no sound for the turn signals, various warning indicators illuminated on the instrument panel, and the vehicle was slow to pick up speed. The dealer was unable to replicate and diagnose the failure for over a month. The vehicle was taken to an independent mechanic for further diagnostic testing. The manufacturer was notified of the failures months later to determine if they may be able to provide a solution to repair the vehicle. The approximate failure mileage was 14,000.

Upon entering the highway the 2007 acadia would not shift either into or out of 3rd gear, I'm not sure. I could not tell what was happening and when I determined this was not going to correct itself I exited the highway. I've recieved a letter from gm stating that vehicles equiped with 6t70 and 6t75 6 speed automatic transmissions are experiencing cracked or fractured wave plates. This clearly is a faulty part as it is occurring on many versions of this vehicle and has been upgraded. I was lucky in that it was only me in the auto and not the entire family when this happened. Very dangerous.

After taking my vehicle to phil moore buick gmc on 10/16/2014 and paying $1341.10 for repairs after a check engine light indicator, the check engine light came on again on 10/20/2014 and caused the vehicle to slow from 60 miles per hour to 20 miles per hour on the highway. When the vehicle was returned to the dealership on10/21/2015, I was told there were additional repairs needed on the engine at an estimated cost of $2789.18. Because repairs had just been completed on the same area 5 days earlier, I called the gm corporation and I was informed that repairs to the engine should have been covered under a recall and the dealership should have noticed the recall at the time of service.

While traveling down highway, car displays message "service stabilitrack engine power reduced". Car slows down and shakes. Turning car off for a few minutes then turning back on clears issue, however, happens multiple times daily. Very dangerous while traveling on highways or freeways.

This car is dangerous. Driving 65mph on freeway when every service and warning light went on. Replaced entire instrument cluster and replace ipc, could have killed us and others. Also engine was removed to repair engine front cover leak at 39,000, now at 85,000 same leak repair is required at cost of $2926. That means every 40,000 miles you need to spend $3000 and have engine removed. Power steering always made whining noise which I was told is normal. At 85,000 was told steering rack and pinion gears need replacement and I am sure the pump needs replacement as well $2000. When driving on the freeway could not stop on exit without brake pedal being pushed all the way to floor, stabiltrak light on could have killed us or someone. Had to replace brake master cylinder. Water pump was leaking after engine was put back in from 1st repair of front cover engine seal. Timing chain has stretch you can hear it, but they only added thrust washers. Rear liftgate - while loading groceries lift gate free fell closed on daughters head. Was told rear lift gate shocks failed. Could have killed someone. This car is a death trap. Don't buy it.

I was driving home from work around 5:05pm on the 5 north freeway going about 65 MPH. All of a sudden my check engine light went on and I felt a sudden loss of power in my acceleration. As I stepped on the gas more to keep up with the flow of traffic, the RPM needle jumped up to between 4 and 6 on my gauge, but my vehicle wasn't going any faster so I had to steer to the right to get to the exit. I was barely able to exit without almost getting rear ended but I had no choice as my vehicle would not go over 40mph. After getting it checked at the nearest shop, I was told that it was a stuck solenoid. After I got that fixed, 4 months later, same problem, but now the dealership is telling me they will have to rebuild my transmission due to a broken wave plate, which will cost me at least $2800, which I don't have.
