Takata recall- I purchased a 2008 GMC awd Acadia about a year ago. While test driving the vehicle I noticed a whiny sound that I informed the dealer about upon return. The dealer checked it out and told me it just need power steering fluid. So he filled the fluids and I heard nothing for a month or so. I took the truck back for misc. Repairs two other times after that regarding sounds that I was heard coming from the vehicle. After that things seemed fine for a few months or so. Early September, the truck slowed down on the highway. The dash was reading 60mph but I was really going 30mph. Then while exiting to turn off the highway the power steering began acting up and was extremely hard to turn. I almost ran into the wall not prepared to use such force. August 29th I went to jiffy lube and had the fluids topped off and power steering fluid was full. I put the truck in the shop for a full diagnostic after the battery went completely dead and the vehicle would not start in October. They informed me that the power steering rack needing replacing and the faulty sun roof had flooded the entire vehicle with 1 1/2 inches of water. The battery died because the port was filled with water. From the beginning of September, when the power steering went out, the vehicle has only been driven very short distances (to the gas station on the corner, less than a mile). I called a gm dealer to check for recalls and there are none which is sad and a total rip off.
My 2008 GMC Acadia leaks water in several different locations inside the vehicle when it rains. It has leaked water through the air bags and I'm now concerned that the air bags could be water damaged and compromised. It leaks through electrical components. It smells like mold and mildew in the car. Condensation builds up in the car frequently after it rains. The car will also sputter and act like it is going to stall out while driving on the highway sometimes. It tells me to �service traction controls� and �service stabilitrack�.
Driving at 35mph, touched brake to slow down for a stoplight, vehicle stopped running. I placed in park and turned ignition to restart vehicle, stabiltrack light came on, and drove home with no other incident. Had a full tank of gas.
Engine light came on took it in to get checked the GMC dealer said it was purge valve and may be my timing chain belt! and my master cylinder was leaking into my booster, and they had to replace a sensor for the tire and service the track/stabilitrak! services came to $1000 now come 2 months later to Jan 2014 engine light is on service stabilitrak is on take it back, my timing chain needs replaced@ 74000 miles which is about a $2000 job and my transmission platelets need changed! transmission is now slipping we called gm and there is nothing they will do as I was informed these are "command problems " in these vehicles!! what!! I feel like I've been sold a lemon and no one are gm cares because these are command problems for them! never again will I buy a gm and I'm confused on how so many people have these same issues and gm is doing nothing about it! OH did I mention you can't park on a slant or an incline with a 1/4 tank of gas because your Acadia won't start! this car has been a nightmare!.
8/26/2011 - 71,309 miles - water pump went out and had to be replaced. 5/07/2012 - 86,885 miles - transmission shuttered when coming to a stop in traffic. Would not start and had to be towed to mechanic. Transmission assembly replaced with gm reman transmission due to broken reverse wave plate that damaged the carrier, sun shell and metal throughout. Also detected an oil leak in the engine front cover that needed to be repaired and heard power steering noise so bled power steering system. 12/31/2012- 100,947 miles - headlight switch fell inside dash panel. 7/26/2013 - 112,506 miles - power steering has never worked properly. It has always made noises and has been stiff. Had it bled several times with no improvement. Power steering went out while making a left hand turn into a busy intersection. At shop now to determine if it needs a new power steering pump, rack, and/or serpentine belt. I have read many complaints with the same issues as those that I have experienced. I am disappointed that gm isn't more concerned about the safety of their consumers and the reliability and quality of their vehicles. I have never owned such a lemon! I personally will never own another gm product. Going back to Lexus.
Most recent incident was 5-25-2014- transmission wave plate broke. I have learned that these plates were not stress relieved on the 2008s. 02-2014 water pump cracked and had to be replaced, this caused a total system failure while driving. Vehicle has been towed at least 3 times. Vehicle currently in shop, all repair paperwork is in the vehicle. I don't remember the specifics of the first time, it was days after I got the vehicle.
My husband and I purchased a new 2008 GMC Acadia in August 2009. Within the first year or so I noticed that the headlights were dim and the plastic over the lights started to peel. I contacted the dealership and they said there was nothing they could do, that wasn't covered under the warranty. I called gm direct and they also said there wasn't a recall and that it was probably a chemical that we used to wash our car, that caused the peeling. They quoted me $800 for a new set of headlights. . . Ugh. . . A year or so later, I began having trouble with the struts. They began to leak. I thought it was my brake line and I took it into the shop and they told me that the struts were bad and needed replacing. At that time there was around 36,000 miles on the vehicle. I had them changed out and the mechanic told me they were the worst he had ever seen. After the repair, the vehicle has never been the same. It's not near as smooth as it was and it makes noise. I had it checked to be sure they were installed properly and they were. The whole process cost me about $900. 00 the next issue I have had is more sever. This just happened a few months ago. I was taking my children to school and the vehicle stalled. All the lights came on and said stable track went off and the engine lost pressure and the vehicle stalled. After it cooled down I could drive a little further and the same thing would happen again. I took it back to the shop and they said it was the throttle and it would probably need to be replaced. They cleaned it for now, but I am scared to drive it anywhere! now the power steering is making noise when you turn the wheel, sounds like the power steering pump might be going out now as well. The vehicle only has 65,000 miles on it. .
