2009 GMC Acadia Owner Comments

problem #4

Car was on cruise control at 75 mph and climbing a hill, check engine light started flashing so I cancelled cruise control, when not accelerating check engine light would not illuminate, upon acceleration, light would flash again. Mechanic ran tests and found that the catalytic converter was so hot that it melted his rubber mallet. Could have caused a fire.

While driving the vehicle the check engine light comes on and the vehicle monitor text says to pull over and turn car off. This is done and after 30 minutes we are able to take car to local shop, since dealership is 30 minutes away in snow conditions. After diagnostics malfunction indicator lamp is on due to poor acceleration, ice deposits and oil deposits in air inlet duct. Due to all the oil and ice deposits all spark plugs are replaced, but I was told if I don't replace the valve cover which are the original to the car, I will have to replace the plugs about every 15K to 20K miles. When I talked to GMC cs they told me to call local dealer which in turn said they could do nothing for me. I would have to replace the valve covers at my expense.

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.

Acadia 6-cyl

  • 43,500 miles
Driving on sr at approx. 65mph when check engine light comes on and "engine power reduced" is displayed. Car slows dramatically and eventually comes to a stop. Power steering is also lost concurrently. After swerving into opposite lane, I managed to get car off to the side of road. Car was towed to dealership (courtesy GM roadside assistance). Fuel pressure sensor was replaced after finding the sensor intermittently shorting and causing the low pressure condition. The power steering assembly was also leaking. The steering gear was replaced and flushed. Exactly one week later while driving on the same sr at approx. 55mph, the check engine light came on and "engine power reduced" is displayed. Car slows dramatically and comes to a stop. However, this time I was able to steer car off the side of the road with no problem. Heavy smoke was also coming from the exhaust and the car smelled unusual on the interior. After waiting 3 hours for a tow (GM roadside assistance), the car was towed to the dealership. Two fuel injectors were found leaking (# 1 and 3) and were replaced. Fuel injectors 2, 4, 5, and 6 were rebuilt. This same vehicle had two fuel injectors (#3 and 5) replaced in August 2011 when this same chain of events occurred (previously reported). I am concerned as to why fuel injectors in this vehicle continue to fail causing the engine to flood with fuel. The safety concern is the vehicle will decelerate and stop with no warning which could cause a fatality if I were on a interstate with little to no shoulder.
