Acadia

  • 71,000 miles
Water water water leaking in vehivle everywhere. Dripping from rear overhead lights, rear back-up sensor, around emergency brake, A-pillars are soaked, pooling on driver side floor. Water and electrical = nothing but problems and more problems. This is now our second Acadia in the last month first was a 07 which water was also leaking from even more areas (opened overhead dvd and water just poured out). That vehicle was fixed per tsb yet problem never solved it just continued to leak. Dealership bought it back once they found us a different Acadia which I now have a 08. They said they found out that the 07's water leaking was a major issue but not with the 08's. well we signed the papers on March 1st and no suprise water leaking everywhere by March 10th. I contacted GMC and was told to have it diagnosed and then they will pass it on to some other department claim specilist person to see if they can help. Oh yeah and found out from GMC that the tsb for drain tube extensions has already been done on vehicle. I am hopefull that GMC will take care of this issue at their expense. ---with the first vehicle, after water issue started my wife would be driving and the power seat would move all the way forward and she could not stop that from happening. She tried to hit the button to stop the seat from moving but it was non responsive until the seat was all they way forward. My wife as very long legs and said if she would have had to make any sort of emergency manovers she would not have been able to. If GMC does not reslove this issue I plan on start the process of a class action lawsuit for all affected Acadia owners.

Acadia 6-cyl

  • 48,984 miles
Water leak from either sunroof drain tube or faulty seam seal, caused water to come into vehicle causing floors and doormats to be wet and cause moldy odor. Also caused major corrosion to harness and fuse box. Told there could be more corrosion, but won't know until they pull those parts out. I have researched water leak recalls for GMC Acadia's, and although it is currently not a recall, it is a very common problem that happens in many Acadia's, therefore, I believe this problem should be made a recall! I am told that water leaks are not covered under my limited warranty and they only offered to go half with me on the repairs. Told it will be between $900-$1,600. Even going half on either of those amounts, I do not feel it is fair that I pay anything toward a problem that GM knew about when the Acadia came out in '07. Instead of doing something about it back then, they opted to wait and deal with it on a case to case basis. This is not fair that we consumers have to pay for their poor workmanship! GM should be held accountable for their negligence in selling a vehicle that has proved to have continuous water leaks.

Acadia

  • 39,000 miles
We bought the Acadia used from a local dealer and the first time it rained significantly water leaked in around the door post at front of vehicle. This leak caused some of the electrical boards to short out which allowed us not to be able to shut the vehicle off even with the key removed. We took it to the dealer, they informed us about the electrical boards and stated the charge to repair. After a call to GM complaint line they repaired the board at no charge to us, but after about 2months same problem accrued same issues. Dealer said water still leaking in but could not find, they dried out the electric connections and said to try it again. After 2months the problem happened again to no help from dealer, my concern is fear of fire from shorted boards or the build up of mold under carpet. Any help or direction would be greatly appreciated.

While it was raining outside, I was sitting in the back seat and happened to look up and saw water/ rain trickling out from around the rear interior overhead light, it was also coming in around the sensor in the overhead. The trickle eventually slowed down to a drip. In my opinion, water and electricity don't mix.

Anytime we get a heavy rain water makes it's way inside the roof of the vehicle. I've got water coming out of seat belt panels, overhead lights, and all over the place. Water/mold and electricity don't mix.

GMC is aware of the problem with the Acadia that the car leaks water from the roof, and I mean pours in. This water also enters the electrical system of the vehicle and affects the airbags. This is a huge safety concern for me. There is no telling what other safety features will be compromised with this water leak issue. Any help concerning this issue will be greatly appreciated.

Acadia

  • 69,000 miles
The vehicle was leased new in 2008 and had water leaking around sunroof. The leak was repaired however between 08-11 there were numerous documented issues with electrical problems on this car relating to the water leak. On October 11, 2011 I was driving to work in the vehicle and all the electrical components shut off- radio, directionals, gages, lights. The car remained running and within seconds the electrical was restored. It has continued to shut on and off intermittently since then. I brought the car to the dealer and was told they were unable to diagnose the problem and that I should bring it back if it happened again. On the way home it happened again. I brought it back on Oct. 12 and the same thing happened the whole drive to the dealer. They have since had the car and tell me they do not know what the problem is or how to fix it. I am being left to drive an unsafe vehicle and am told my only option is to trade it in.

Acadia 6-cyl

  • miles
Purchased a used 2008 GMC Acadia slt1. We have had it for six days. Within those six days we have had water rolling/rushing around our roof liner, water pouring out of both front airbags and under dash, water pouring out of the back dome lights, rear video sensor, and back seatbelts. Both front floor mats saturated with water as well as the carpet underneath. It is to be noted that all of the water pouring out has been witness while driving. This is clearly a driving distraction especially to a new car owner who is not expecting this at all. A driver is not supposed to have any driving distractions while driving. This car was designed with a lot of safety features however water leakage and pouring out of spaces has been greatly over looked. Last night while driving at night in the rain, I had water drip onto my hand from the driver's airbag which took me off guard as I was not expecting it. This was a distraction. We have put our basement room dehumidifier in our Acadia in the garage on this sixth night to help dry out all the water in the carpet and we are sure in the roof liner to hopefully help with any mold that may have started. We have two sons undercare for environmental allergies and one with asthma. This vehicle cannot be good for him. We now are stressed worrying about what future problems we are going to face from the water damage we can see and that we cannot. The upper electrical components (I.e. lights, dvd player), the blower under the dash and other internal dash components, and the most serious are the airbags. Will they now work" this has to be the biggest safety concern for GMC. We now have a big false sense of security regarding the air bag deployment in the event of a crash. We cannot comprehend that this has been allowed by our national government safety agencies since 2007! why"

Air cond turns on but will not blow. Mechanic removes cover and my blower motor is standing in 3 inches of water. Any more water would have leaked onto the floor of my car. Water in an electrical component is not safe. If I get water inside, I will also have mold or mildew. This is not safe for us to breathe. I do not feel this should be my cost. This is manufacturing or engineering negligence. It is not normal wear and tear.

This is in regards to the window seal on the driver and passenger window. It holds water in the seal and has a very strong offensive mold/mildew odor. Each time you roll down either window the smell is so strong that your allergies are immediately affected. I don't think it is healthy to constantly smell mold when you're driving your vehicle. I took it to the dealer a couple of times and they agreed that it was horrible, but only suggested that I take an air hose and blow out the trapped water. That doesn't work because each time it rains or you wash your vehicle it smells again. I hate driving a newer vehicle that smells like a molded trash container. I would like a better solution for this never ending problem.

Acadia

  • 40,800 miles
The contact owns a 2008 GMC Acadia. The contact stated that on March 20, 2010 while driving at approximately 40 mph in snowy conditions with rocks and debris on the road, he heard a loud clanking noise under the vehicle. The noise was followed by the check engine light which illuminated on the instrument panel. When the contact attempted to accelerate at a traffic light, the vehicle would not move. The police responded but no report was filed. The vehicle was towed to a local authorized dealership where the contact was informed that a rock under the vehicle cut the harness wire since it was unprotected. The vehicle was repaired. The failure mileage was approximately 40,800. The current mileage was approximately 41,000.

I purchased my GMC Acadia '08 slt-2 in February, 2008 from the first owner with only 4800 miles. A month later, I noticed water dripping from underneath the glove box and immediately took it in for the "recall." They "fixed" it, and much to my delight, I had no problem until about two weeks ago (almost a year with no water). Then I noticed the leak again--same spot. I took the car back to the dealer, and they attempted the repair once more, claiming it was some sort of loose grommet. Again, they "fixed" the problem and sent me on my merry way. The next day, it poured, and even more water came from behind the glove box. I again took the car in, and this time, they held it for three days and apparently found two leaks, the more significant of which was from the lack of adequate silicone fastening the plastic shield underneath the windshield wipers. I picked the car up this morning, and like the rest of the country, we in new england are experiencing heavy downpours... and alas, the car is still leaking. I must say that the customer service team at colonial GMC in watertown (MA) has been extraordinarily kind and accommodating, but they still have yet to fix the problem.

The contact owns a 2008 GMC Acadia. Whenever it rains, the contact's vehicle leaks badly through the sunroof. The dealer repaired the vehicle, but water began leaking through the windshield and is currently leaking in the rear of the vehicle. The contact is concerned about mold issues. Whenever she takes the vehicle to the dealer, she is informed that the vehicle has been repaired. However, the leaking recurs once she retrieves her vehicle. The failure mileage was 27,214. 4/01/09 updated 04/06/09.

Water leaking from improperly installed sunroof drainage system. Water leaked from headliner, a post, B post, under dashboard, and pooling in the driver side floorboard. Incident occurred 3 times before being fixed. Known issue by manufacturer when vehicle was being produced at the factory. System was not resolved/repaired until attention was brought to the service department by the owner of the vehicle. Manufacturer should have fixed poorly designed system prior to producing, selling the vehicle to end consumer.

Water leaking from sunroof - leaks from both airbag areas, above sunvisors and through seatbelts. Have serviced two times and will be going back a third time this week. First occurred 6 days after taking car off lot, then again 1 month later and now 18 days later (each time it has been in the rain). First time, took out windshield and replaced, thinking it was loose seal. Second time said the strip around the sunroof was flat and replaced it. This time they think the front drainage tubes are not working and are backing up into the inside and leaking. The mechanic rode with me and could feel the water puddling up in the sunroof. I am afraid the water will create mold and mildew, as well as get into the electrical components of the vehicle. The water pours out of the front sides and onto the steering wheel as you are driving.

Acadia

Entered my fairly new 2008 GMC Acadia this morning and was greeted with a puddle on the passenger seat and the door jams leaking to a point where the roof liner was also soaked. I am now afraid the water may compromise the air bags and speakers that are located near the leak. Not to mention the odor that will occur from having soaked carpet in a vehicle. I don't believe a vehicle with 10,000 miles and cost me 36,000 dollars new should ever leak.

This is the second time, within two weeks, I have taken my GMC Acadia slt2 AWD 2008 to be serviced for a leaky sunroof. I am getting major water damage in the wiring system, and airbag holder. I have more miles on my rental van, then my brand new Acadia.

Acadia 6-cyl

  • 400 miles
I purchased a GMC Acadia slt2 AWD 2008 on 5/21/08. 5/31/08 my sunroof leaked, and started dripping out of the airbag holder. The water went into the dashboard into wiring, speakers, vents and then continued to drip onto the floor board. 6/1/08 I started smelling a chemical, which smelled liked a strong odor of propane "like" smell. I have been getting sick and nauseated, along with my three girls. I am concerned about my health, moreover the health of my girls and husband. I also, planned on selling real estate residential property with my Acadia. So, I'm concerned about my future clients, and customers. The dealership, auto town Buick Pontiac GMC, 16803 SE mcloughlin blv, milwaukee, or 97267, has been unhelpful, due to them "possibly"buying back my GMC Acadia. The sales manager, moon, has been unprofessional and incompetent.
