The contact's husband inspected the engine and had the vehicle towed to the residence. The contact's husband replaced the crank shaft position sensor, purge valve, high pressure tank, fuel pump, and battery; however, the failure persisted. The contact then towed the vehicle to an independent mechanic where it diagnosed with engine failure due to the timing chain, and a cylinder #1 and #5 defect. The manufacturer was notified of the failure and informed the contact that there were no recalls on the vehicle related to the engine. The vehicle remained in possession of the mechanic unrepaired.

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.

My car completely died while driving it a few months back. Just got it back after about 3 months, partial sucky dealership, partial back order issue. Turns out the sunroof leaked into the dash. Had to replace the body harness and something with the dash. $5100. I estimated on the date it happened because it's been awhile.

My vehicle turned off while driving on a side highway, and was unable to be jump started. Took it to a mechanic and found the ECM was bad. Mechanic called different dealerships to price an ECM, and was told by each dealership that this is a common problem. He was informed that even with a new ECM installed, it may go out in another year.

Car stalls as I am turning into parking spots, turning or going around significant curves in the road, while im in a round about etc. Luckily I have been able to put the car in neutral and it starts back up and off I go. I am the second owner of this car and I bought it from a non gm dealer. My mechanic is at a loss as to what is wrong because a) there are no codes that are coming up and b) the stalling is very sporadic, it will do it twice in one week and then not do it again for 3 weeks. I have had this car about 5 months and it has happened about a dozen times. I pulled the carfax and called the dealership that did all the work on it with the previous owner. After speaking with the service department, I was told that the previous owner had the same problems and the dealer could not get the car to malfunction while they had it in for servicing. Although she didn't tell me everything that they did to try and resolve the issue, I do know that they went as far as to replace the cylinder head hoping that would solve the issue, but clearly it did not. This is a very dangerous safety issue, I have almost hit several cars due to the fact that when the car stalls, everything locks up and you have no control over anything.

Vehicle had a slight misfiring when climbing incline. We replaced two spark plugs. Misfiring calmed down. A couple days later misfiring resumed. Husband was driving daughter to daycare when car had multiple dts codes appeared (stability track, check engine, reduced power) with car suddenly stalling while on a highway leaving barely enough time to coast off the road and out of the way of traffic traveling 60mph. Gmc refused to assist us on this issue until we found online a tsb about the timing chain which had broken. Due to the constant misfiring (direct result of the timing chain) two of my catalytic converter became clogged. Those have now been replaced out of my pocket however when driving vehicle home while it does run smoother it now misfires all the time even when not going up hills and idling very low and misfiring while idling. I am scared that while driving my vehicle this may happen again because the issue has become worse.

While at wyatt johnson dealership to buy car, salesperson, [xxx], states there is a problem with the plastic pieces attached to floor mats. States he needs to order them and bring car back in. Less than week later, check engine light comes on. They kept car for a few weeks because they state they needed to order a part that they did not have in. Finally picked up car to realize there was so many miles on it that I thought it was not the acadia we bought, or they set it up on a dolly to let tires rotate to hike the miles. They knew we were moving soon, military, and did not have time to do something about it. Within a 100 miles the check engine light came on again. Long story short, this happened time and time again where dealership would have car for weeks with us to drive around a $5000 loaner vehicle while making payments on a $40,000 vehicle. Because we were not stationed as same state as where we bought it, no gmc dealership would take the vehicle back as a lemon. Twice we ran from the vehicle fearing for our life because it stalled, smoked, and had the smell of gas in the cabin area. No dealership at new duty station would take the car back without sever penalties, and said we would need to return it to the state we bought it in order to turn it in as a lemon, however, the vehicle was not safe to drive from florida to tennessee. Keep in mind the car went in and out of shop 8-10 times with them keeping the vehicle weeks at a time. We paid $680 with 0% interest rate a month for the car to sit at the dealerships. Frustrated, we told the dealerships in melbourne fl and ally financial we were too scared to drive it, nothing the repairmen did helped the gas smell or check engine light, and they could tow it off our driveway. On a car fax report, it shows a title change occurred during the time they kept it. I feel sorry for whoever bought this vehicle.
