Water Pump problems of the 2009 GMC Acadia

The contact owns a 2009 GMC Acadia. While driving approximately 65 mph, there was a sudden loss of engine power and the vehicle was unable to be driven over 40 mph. The stability traction control warning indicator illuminated. The dealer was unable to replicate and diagnose the failure. In addition, while driving highway speeds, "engine hot" and "a/c off" appeared on the instrument panel. The contact noticed smoke under the hood. The vehicle was coasted over to the shoulder of the road and turned off. The vehicle was unable to be driven due to the failure and was towed to the dealer. The dealer diagnosed that the water pump needed to be replaced. The dealer replaced the part. The manufacturer was notified of the failures and indicated that they also had campaigns that needed to be addressed. The timing chain needed to be replaced, there was a loss of power steering assist, and the transmission cutlet leave plate failed. There were no recalls. The VIN was not available. The approximate failure mileage was 78,000.

I was driving my car at about 70 mphs on the interstate and the car began to slow down and check engine light starting flashing. I almost got hit by the drivers beside and behind me. While honking my horn and putting on the emergency lights I was able to get over to the side of the highway. Towed my car into the dealership and they keep it for about 8 days saying they were very behind. Notified them that my car was coming in for service and was never told they was behind. Finally about 7 days later the dealership is saying they don't know what is wrong with my car. Then on the 9 day the service guy calls me and says they think its the motor but they would have to take it out to see. Possible cost would be any where from $4,000 to $7,000 to fix the problem. There are several special coverage open on my car such as timing chain , water pump shaft seal, loss of power steering and throttle body. After reading other GMC customer complaints I feel it is the throttle body that needs to be replaced. Dealership states they don't know whats exactly wrong with my car but can't figure it out till they take out my engine.

We purchased a 2009 Acadia from a reputable dealer that claims quality in regards to their used vehicles. We have had the vehicle for 6 months and the vehicle has left me stranded on different occasions and compromised others individuals and my own well being. First incident the car was in gear but would not start. We never found the reason the vehicle would not start. The battery fully charged. No other issues noted. Second incident the vehicle the vehicle again did not start after several attempts to start. Eventually car just started, no issue was uncovered as the culprit. The vehicle overheated out of the blue while in route to respond to an emergency call and had the water pump replaced. While on the interstate with my 4 month old grandson the vehicle jerked after reaching the speed of approximately 65 mph and then the rpm registered about 3800 to 4500 and the vehicle came to a crawl on the interstate. The check engine light came on and I took it had had diagnostics ran and it indicated transmission concerns. I took the vehicle to the dealer and the light had gone off and the dealer stated that there was nothing found. My husband and I left and while in route to another city the vehicle again jerked at approximately 65 mph and the rpm once again registered between 3500 and 4500. We were able to crawl along at about 25 mph and barely made it safely to a certified GMC dealer which stated that the transmission was completely gone and we needed another and the cost would be approximately $3900. The dealer refuses to honor or stand behind their product. We recently had the vehicle at the dealer to ensure safety recalls were taken care of, the dealer indicating no concerns after a "proposed" inspection. There is clearly documented concerns with this issue. We were lucky as there were no injuries, but the situations that we were left in were extremely dangerous.

At approximately 90,000 my engine began misfiring. I took it to a local shop where they performed a full tune-up and replaced all of the plugs. However, there were also coils that were bad and had to be replaced. A week later, my check engine light came back on and the Acadia was missing again. I took it to another shop where they showed me that the plugs were already charred and needed replaced again, and there was another coil pack that needed replaced. A few days later the check engine light came back on and a co2 sensor was going bad so I replaced it. A few days later the check engine light came back on and the GMC dealer told me 2 of the 3 catalytic converters were bad and needed replaced. My check engine light is still on and I'm just waiting for the thing to explode while I'm driving it. After reading other similar complaints about power steering and engine problems with Acadia's, I'm convinced a major investigation into these vehicles and their safety needs to be launched by the gov. Now there is an air bag recall and in the past have had headlight recalls, water pump recalls, and who knows what else. The whole fleet should be declared lemons!.

Bought used 2009 Acadia in 2011 with 55000 miles and nothing but headache 1) 60k miles: liftgate came crashing down my wife’s back while getting the groceries. They should have some safety measures to stop the gate from crashing. 2) 70k miles: truck wont start in drive way. Towed truck to dealer and they changed fuel pump. 3) 70k miles: engine misfire code. Replaced one coil. 4) 76k miles: coolant always low. Dealer changed water pump. 5) 76k miles: truck hesitate and feel a misfire between 45 and 55 mph. Took truck to dealer and they quoted me over $3300 to replace all coils, spark plugs, steering wheel column and steering rack busing. 6) since we bought the car we cant even drive it with the windows down or the roof open. The truck shakes roughly with both roof and windows open.

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.
