We got this 2007 GMC Acadia at 100,230 miles on August 2014. Now it has around 133,800 miles. At 115,000 miles it stated to have issues where it said stability track. The traction control turns off by itself and not sure if the stability and this are the same thing. Some electric parts have already failed. The charging outlet and electric windows don't work right. The passenger side can not be put down by driver side. The rear right side can only be put down of up by the driver. The left rear does not work when the driver puts it down or up. The power in the lift gate in the back has gone out. It only opens or closes manually. There was also a recall with the lift gate and we got it fixed. After it was fixed then a while later it would close on us and it almost hit us but we reacted fast. It only closed on us about three times then it stopped working. …
Our vehicle only has 86K miles and the rack and pinion is leaking heavily. The dealer stated that this is a known issue, but it is out of warranty. Sometimes, the power steering cuts out and it is very difficult to move the steering wheel. We believe that this imposes serious risk while driving and the problem can happen at any time. There is no repeatable scenario to demonstrate the failure. It is random. The front engine cover also leaks oil heavily. The dealer also stated this is a known issue. This could result in rapid engine oil loss and engine failure while driving. I took the vehicle to the dealer yesterday for inspection. Unfortunately no pictures were taken, but their two technicians inspected the vehicle and agreed on the known issues. The service advisor also agreed on the known issues. …
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.
At 80,000 miles transmission went out and had to be rebuilt. Car is also leaking under the passenger and driver floor board and moon roof/sunroof drips down from dome lights onto third row seats. Leaking has caused multiple electrical problems. When there is a heavy rain ignition will still run even after key is turned off and key is out of ignition car is currently at 130,000. Also ignition will power down even while care is in motion warning light will illuminate stating "engine power reduced" "traction control off" and vehicle will not move. Car has had more problems than any other I have owned, will never purchase another GM vehicle.
