2012 GMC Acadia Owner Comments

problem #4

My wife and three daughters, ages 11, 9, and 6, were involved in a major crash. An elderly male traveled thru a steady red traffic signal and struck the passenger side of my wife's vehicle as she was crossing the intersection with a green traffic signal. After impact, they were pushed head on into a traffic standard (which was taken out completely) and then into a telephone pole, also head on. Not one airbag deployed. The vehicle is supposedly equipped with front and side airbags. In March of 2014 there was a recall concerning the airbags not deploying in these vehicles (# 14V118000). I have owned this vehicle since new and did return it to the dealership in may of 2014 for the recall shortly after receiving notification. I was advised that it was taken care of.

Timing gear cover on front of engine leaks oil. It happens after every use and appears to be a widespread issue with the 3.6L V6 engines on the GMC Acadia, chevery traverse and Buick enclave. The seal on the front engine fails and lets the oil out of the engine. If not caught, oil pours into the engine posing a fire and control hazard.

While driving on the freeway noticed the engine light start to blink for the third time. Also notice the traction control come on by itself at the same time. While pushing on the gas pedal the cars RPM went up but the speed was decreased. I pulled the car to the shoulder of the road and turned off the traction control manually. I set for about 10 minutes until the light went away. I took the car to the dealer so that they could read the code history. The result was that the car misfired on cylinder 1, 3 & 4. the tech told me that they couldn't figure out what the exact cause was unless the light was on while at the shop. But if it was to happen again to take it back in for further review of the issue.

The contact owns a 2012 GMC Acadia. The contact stated the engine failed and engine fluid leaked on the ground while the vehicle was parked.

The steering wheel also began vibrating and shaking. The warning lights illuminated on the instrumental panel. The manufacturer was not made aware of the failure. The failure mileage was 2,505. The current mileage was 7,454....updated 07-29-13 the consumer stated the brakes squeaked and the gas gauge would not register gas being in the vehicle. Updated 08/01/13
