Acadia 6-cyl

  • 101,745 miles
While driving to work the car check engine light came on and said overheating pull over. After pulling over a local shop towed me back since the nearest GMC dealer is 30 miles away and the snowy conditions are safe to drive in with a car that is acting up. Once at the shop it is evident the water pump is leaking at the shaft seal. Due to the nature of the issue I was unable to Transport my car to a GMC dealer for repair, thus the cost of this repair is again my responsibility per GMC "customer service". at this time I am in deep regret of my purchase of this GMC product and will be wary when I look to purchase my next product.

In slowing at manual stop sign, the engine accelerated (while I had my foot on the brake) to a very high revolution--approximately 4,000 to 4,500 revs--and I had to put all of my leg strength into pushing the brake pedal to the floor, while I hurried to shut the engine off. Once I had turned the ignition off, the engine did shut down the way it should have. Once that was accomplished, I started the engine up again and it ran without any further incident. It was a few months later before another such incident occurred. The second time this same type of situation occurred under virtually identical circumstances, I took the vehicle into pat mcgrath GMC's service department and explained what had happened. The service manager immediately drove the care to test it, but naturally the car didn't act up. At that point they attached a monitor to it and told me to drive it until the problem recurred, but after a week of no such problem occurring, I had them remove the monitor ironically, the problem occurred under exactly the same circumstances the next morning. So far I have had this same experience recur approximately 6-7 times as I have been slowing down to stop the vehicle, the engine would rev up badly, but I already had the brake on to stop it, put it into neutral and shut it off. On restarting it did so properly and there was a time lag between problems. GMC is now aware of the problem as I had posted it on the acadiaform.net. At they point they had had no other such issues brought to their attention...

My air conditioning has never been cool on my vehicle, especially in extremely hot weather. I took it in to the dealership several times with the result being there is nothing wrong with it. Finally on the 4th of July it stopped working completely. It was blowing hot air. We took it to the dealership again and they said that the compressor had been failing for some time. Metal shavings had come off and clogged the condenser and filter. The dealership replaced the compressor and the condenser. The air conditioning still is not really cold, but at least it isn't hot.

I had just picked up my car from having the A/C compressor and condensor replaced and I was doing a U turn into a gas station when the power steering went out. I had to manually turn the wheel. With my two children in the back I almost went into a ditch. I immediately called the dealership and took it in for them to look at. They told me that the power steering gear assembly was leaking and needed to be replaced. They found that when the ves valve was commanded shut, the valve would not re-open. The rack was also leaking on the left side. They replaced the gear assembly, set toe and flushed the system. This is a serious safety concern and should be looked into for a recall.

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.

The headlight went out and GMC quoted me at approximately $120 to replace. Husband attempted to replace it but you had to take off the wheel in order to get to the actual light. I gave GMC the go ahead to replace and they called me back and told me that the wiring had melted and that it would now be over $300 to do it. I told them no and made a complaint. They called me a few days later telling me they would do it but I had to pay $50 deductible (assuming they went through some type of warranty). It eventually became a recall and I am now looking into getting reimbursed for my $50. Noticed my car started over heating and took it into a mechanic friend, let us know that the water pump needed to be replaced this was at approx 45,000 miles. I did my research and the GMC warranty covered the cost. At approximately 56-57,000 miles the car started making a whining noise when driven slow or first thing in the morning when it was cold. Took it in to GMC to get it checked out and it turns out that the steering rack had a leak on each side of the wheels and pinions, and power steering pump needed to be replaced. Quote almost $1500 dollars. I could not afford that price so took it back to my mechanic to see if it would be cheaper. He ended up replacing the pinions and rack but said the pump did not need to be replaced and ended paying $600 out of pocket. I'm hoping that GMC will see that many of us are having the same problem and will make it a recall. I will not be buying anymore GMC vehicles. All I want is a reliable car that won't break the bank.

The contact owns a 2009 GMC Acadia. The contact stated that the engine power reduced message illuminated on the instrument panel as smoke and fire emitted from the exhaust pipe. The fire department was not contacted and no injuries were reported. The vehicle was towed to a dealer who diagnosed that two fuel injectors were stuck, which resulted in the fuel lines and engine to become flooded. The dealer stated that in order to repair the problem the fuel lines, catalytic converter, oil and oil filter needed to be replaced. The manufacturer was made aware of the failure who covered all costs of repairs to the failure. The vehicle was repaired. The failure mileage was 23,500 and the current mileage was 24,500.
