The contact owns a 2007 GMC Acadia. The contact stated that while it was raining, water was leaking from the driver's side door into the foot well. The contact stated that the water caused a short circuit, which caused the electrical system to stop sounding warning chimes, turn signals, and the radio was inoperable. The contact had taken the vehicle to a dealer where it was diagnosed that the amplifier needed to be replaced. The vehicle was not repaired. The manufacturer was informed of the failure. The failure mileage was approximately 150,000.
GMC please take accountability for the sunroof leak issue! Years of data, almost 100 complaints, someone should already know about this and have a solution! My car has serious leaking issues from the sunroof above the driver, electrical to cabin doesn't always work except dash lights, and headlights/turn signals work sporadically. The locks work when they're in the mood. Also means ac/heat works sometimes..I live up north and it's 24 today. My windshield wiper fluid remains empty because it randomly turns on and drains out: which also means replacing my wipers is a bad idea because they randomly turn on for at most an hour and dry wiping the window...and destroying the wiper blades. All wheel drive won't work, despite mechanic seeing no issues. I've taken down the mounts and tried to flush the draining tubes myself..and they're clear with no leaks when I tested the tubes. …
I had problems with the transmission when my vehicle had around 61,000 miles. Vehicle was not going over 25 MPH and sometime it did not run at all. I took it several times to the dealer, actually a town truck had to take it because it was very dangerous to drive it. It took a lot of time and effort for me to finally get my GMC Acadia fixed. That was in 2015. Two years later I had problems with my transmission again, my GMC has now 104,000 miles. I went back to the GMC dealer where it was repaired before, but they told me that guarantee had ended 2 months ago and I had to pay $1,021 to get the transmission fixed. I'm also having problems with hood lift and the headlight swith is not working
The sunroof leaks and causes electrical problems. Suddenly while driving the power steering gears, rack, and bushings are defective causing the power steering to go out during low speeds. Tried having it replaced under the recall, however, 9 months later the same thing happened and nobody wants to fix it or allows for the dealer to replace it again. This is a major safety feature that should never be acceptable! Also, the transmission already had to be replaced and is going out again. The manufacture made a faulty vehicle and should be held accountable for these parts and the labor not to mention the inconvenience of having to fight with the dealer and GM to get the problem corrected.
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.
