Either I got a lemon, which is definitely a possibility, or there are significant issues w/ gmc as a manufacturer which is evident. The american car industry just won't do business differently but then again, they don't have to- they get bailed out by the government repeatedly. I leased this vehicle in october, 2012. The issues cited above, were related to 3 bad fuel ignition valves, they were replaced finally after I took the car back to 2 different dealers and nearly 6 months of complaining. The issue was when accelerating, the rpms would stick at around 5-6 when I was traveling around speeds of 45 MPH to 60 MPH. The transmission wouldn't shift into the next gear. This was highway driving, but will happen on 4 lane roads as well. During the same time frame, the stability of the car in ice/snow only worked if the tow package feature was turned on. Otherwise, I spun out leaving our neighborhood going down a slope at speeds of less than 30 MPH. Dealer said it didn't make sense and did nothing. I just keep the tow feature on during snow/ice/rain. Electrical issues, heating/cooling system wasn't working correctly, it wasn't heating unless the temp was put at 80 degrees. Only thing dealer would concede was there was a kink in the hose. It's happening again- we have to set the A/C at 60 in order for it to cool the car down. Very disappointed in this car. Once again, the issue with the rpms and heating/cooling system is happening again. I'm paying off this lease early and hopefully will not get a penalty. This is a poorly made car.
2012 GMC Acadia transmission complaints
Page 3 of 3: complaints 41 to 43 of 43, newest first, as owners wrote them.
Axle rod pulled out of gear box causing the entire wheel/tire assembly to fall down. According to dealer the assembly had not been "machined" at all at the factory and could have failed at any time. The rivets were not pulled out is how this determination was made. It happened with no warning after turning left onto the highway from my driveway at a low speed. Car was unable to be steered or stopped coming to rest about 30 yards after failure. Dealer has informed us that gmc manufacture requested the parts be returned to them and this may become a recall issue due to the fact that the rivets should have been flattened on the assembly line when hit by the machine, they obviously were not and they need to determine how many vehicles may be involved. This is a big, bad deal and could have killed us if we were traveling at any higher rate of speed. Other lives are most likely in danger. The consumer stated the left front lower ball joint separated from the control arm. The rivets holding the lower ball joint were never installed correctly.
Tl* the contact owns a 2012 gmc acadia. While driving approximately 65 MPH, the contact disengaged the accelerator pedal briefly while switching lanes. Upon engaging the accelerator pedal again there was an increase in the RPM reading but the vehicle would not accelerate. The vehicle was taken to the dealer for diagnostic. The technician stated the vehicles computer needs to recognize the throttle gear which caused the hesitation. The technician stated there was no repair necessary. The vehicle was not repaired. The approximate failure mileage was 3,000. The consumer also stated the same issue occurred when slowly approaching a light, that then turned to green before coming to a full stop. When he applied the gas, the engine RPM's would rise, but the transmission did not engage for a period of 3-5 seconds. Updated 04/25/12
