general problems of the 2009 GMC Acadia

The stabilizer/traction control keeps going off and it will stay off. I can turn,hit a bump or start it up and the traction control/stabilizer system is off. I almost had a accident on the freeway in the rain because it turned off out of nowhere and I almost lost control.

I've had electrical issues with the radio. Every single time it rains the speakers go out. Noticed there was water in the electrical connectors on all the doors which also affected my windows from going up and down. More importantly, the transmission is shot now. Was driving to the store, stopped at a stop light, and when it turned green, I hit the gas. My car didn't go. I kept my foot on the pedal with the same amount of pressure and it started to go, but after a few seconds it just kicked real hard into first gear. Felt like someone rear ended me. Every time I stopped it kept doing it. Took it to the mechanic and apparently I need a new transmission and timing chain. The car is only 10 years old and I bought the car 5 years ago from gunn Honda. This is ridiculous! constant problems with this car!.

The contact owns a 2009 GMC Acadia. The contact stated that the headlamps independently failed and the vehicle would not accelerate over 20 mph. The failure occurred without warning. The dealer and manufacturer were not notified. The failure mileage was approximately 90,000.

Takata recall: I'm having idle/stalling issues with my 2009 GMC Acadia. Car cuts off while driving causing a safety hazard. First, I had my car inspected by local licensed mechanic who diagnosed a timing chain issue and cat converter issue. I followed by call a GMC dealer and informing them of my car problems. They scheduled my car for an inspection since they have an extended warranty for timing chains. They inspected my vehicle and informed me since the timing chain wasn't making noises they wouldn't diagnose it as a problem. They released my car without fixing it and my car still cuts off and idles while driving. They also told me about many other issues found during the diagnostic totaling over $8000 in repairs. I called and complained to GMC and they informed me that their are actually many other additional parts warranty's/coverages that they have and may be able to assist me with. I find this very concerning as the GMC dealership refused to properly diagnose and service my vehicle, along with the fact that GMC has secret additional wanrranties/coverages that the general public doesn't know about my car was in the GMC dealer shop for 4 days and they refused to assist me with a loaner vehicle while my car was being inspected. They released my vehicle and now I'm back to square one with the same issues and new list of supposedly found car issues estimating over $8,000.

I have a 2009 Acadia slt2. I was entering the highway and accelerating when the car would not increase in speed as I was merging onto the highway. I was nearly hit by a semi-tractor trailer truck. The same problem has occurred multiple times after this. I have taken the car in for service and was told by a gm authorized dealer that they could not replicate the issue and they replace a coil. The car still does the same thing intermittently. This car has had other safety issues, like water leaking into the cabin and nearly shocking me while trying to drive.

Tl- the contact owns a 2009 GMC Acadia. The contact stated that while operating the vehicle the check engine light would illuminate and the vehicle would suddenly loose acceleration and sputter. The vehicle was taken to the dealer on multiple occasions and the ignition coil was replaced but the failure would re occur. The contact indicated that after experiencing the same failures the dealer diagnosed that the fuel pump module was faulty. After replacing the fuel pump module the failure continued to occur. The vehicle was taken back to the dealer who then diagnosed that the transmission would need to be replaced. The vehicle was not repaired. The manufacturer was notified of the failures. The failure mileage was 30,072. Jft.

The above mileage and dates are approximate--dealer and GMC (case #71-1186898165) are aware of problem which involves a sudden power surge as I have been stopping at my mailbox, stopping at stop sign and pulling into parking place. Each time my speed was slow enough and my foot was on the brake, that I could maintain control while the rpms surged to over 4,000. I put transmission into neutral and shut engine off and, with restart, problem went away. Dealer has attached a monitor to try to identify the error code, but after a few weeks of having it in place, I returned to dealership and had it removed. The following morning it happened again as I stopped at my mailbox. I haven't been back to my dealer to report that incident. Vehicle now has just a few miles over 101,000 and there has been no recent issue of the same type.
