Recently reported STRUCTURE problems on 2008 GMC Acadia

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. *tr

Our vehicle sat out in the rain for several hours because we were at our daughter's sporting event in another town. when we came back to our vehicle to drive home, we noticed the carpet was wet and when my husband pulled forward water began to come out of both the third row light and seatbelts. we did our best to clean the water up and planned on contacting the dealership as soon as we could. we drove the car to work the following morning as this is our main vehicle and when my husband shut off the car he noticed that it was making a strange noise. when he tried to restart the car it would not start. we attempted to jump the car, but it would not turn over. we ended up contacting a towing company to take the car to the local dealership. after a month of our car being out of commission, gm and the dealership have determined that there is extensive damage and we will need to have the wiring and circuit boards replaced at a cost of $6000. gm has completely washed theirs hands of this and continues to say it is an environmental issue and we didn't maintain the sunroof properly (although no documentation was given to inform us that this needed to happen) and clearly they know of the design flaw since they recalled it once for a leaky roof (we had the recall done). there are documented mold issues (which make people sick), airbags that have quit working, defroster motor issues in northern states, in addition to a complete vehicle failure while driving in an undesirable neighborhood. here is a link to edmonds.com where there are many, many complaints. http://townhall-talk.edmunds.com/direct/view/.f1e12d1. *tr

Tl* the contact owns a 2008 gmc acadia. the contact stated that water was leaking through the roof of the vehicle, causing water damage to the interior. the vehicle was taken to the dealer, who stated that there was a defective seal on the roof. the manufacturer was made aware of the failure. the vehicle was not repaired. the failure mileage was 90,000 and the current mileage was 93,000. *tr

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. *tr

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. *tr

Tl* the contact owns a 2008 gmc acadia. while parked, the contact noticed water had entered the vehicle from under the glove compartment and the overhead light compartment, flooding the floorboard. the contact stated that the failure recurred whenever it rained. the vehicle was not taken to the dealer for diagnostic testing. the vehicle was not repaired. the approximate failure mileage was 58,000.

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. *tr

Tl* the contact owns a 2008 gmc acadia. the contact stated that whenever it would rain, water would enter through the sunroof and the instrument cluster. the dealer was notified who advised that they would perform a diagnostic test and inspect the failure. the vehicle was not repaired. the manufacturer was not notified of the issue. the failure mileage was 85,000.

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. *tr

Tl* the contact owns a 2008 gmc acadia. the contact stated that he noticed water on the dashboard prior to starting the vehicle. the contact then attempted to start the vehicle, but it would not start. the vehicle was successfully jump started and all of the air bag warning lights illuminated on the instrument panel. the vehicle was taken to the dealer for a diagnosis. the dealer stated that a seal needed to be placed between the firewall and cab. the vehicle was repaired. the manufacturer was not notified. the failure mileage was 49,000 and the current mileage was 52,000.

Tl* the contact owns a 2008 gmc acadia. the contact stated that there was a severe water leak coming from the moon/sun roof and into the instrument panel, causing a shortage with all of the electrical components. the vehicle was taken to the dealer who replaced the headliner that surrounded the moon/sun roof area. the replacement did not correct the failure. the manufacturer was notified who stated that the failure was caused by an engineering flaw and offered no assistance. the vehicle was taken to the dealer four times for repairs. the contact filed a claim with the manufacturer. the failure mileage was 53,000 and the current mileage was 56,000.

Bought our gmc acadia dec. 2011 had no issues till jan 2012. since then it has been back to the dealership repeatedly for seemingly linked problems. started with just a dead battery upon further investigation found that the wiring harness was submerged in water, causing battery to short out, replaced the battery and fixed the apparent point of entry. not two weeks later back in the shop, water pouring from the head liner (around the interior lights, sunroof moldings, and seat belt joints). our acadia remained at the dealership for three days with no luck of finding a leak (checked all drain lines and ran the vehicle through the water machine). here we are again vehicle has been at the shop for a week with no luck of finding the point of intrusion; this time the water leak shorted out the entire fuse panel. after trying to find the leak for over a week, sending the vehicle to another shop to "get a fresh set of eyes on it", and contacting gm for advise (which was no help) the dealership still has been unsuccessful in locating the water leak. not sure what to do next. all i know is we bought a $30,000.00 car so we wouldn't have problems and here we are with problems, expensive problems. *tr

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. *tr

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. *tr

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? *tr

Pushed button for rear-hatch to open. hatch went up and after 1-2 seconds released with all its weight. *tr

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. *tr

2008 gmc acadia slt has severe water leakage inside the cabin that cause significant damage to interior carpeting and panels. electrical problems also begin to happen such as back up assist disabled, air bag light flashing, rear windshield wipers not shutting off and more i am sure will happen as water enters the cabin and areas that you cannot see. this is a potentially dangerous condition that needs to be recalled and addressed by general motors. fire hazards and injuries due to malfunctioning equipment might occur. there are videos and plenty of complaints from other owners on the internet of this same issue and i am shocked that no actions have been made by gm. *tr

Tl* the contact owns a 2008 gmc acadia. the contact stated that this was the second time the sun roof drain line shifted and leaked water down the headliner. the failure flooded the driver side of the vehicle, side air bag, and visor without warning. the dealer diagnosed that the sun roof drained cube shifted and needed to be replaced. also, the carpet and panel of the driver side had mold and needed to be to replaced. the vehicle was repaired. the manufacturer was made aware of the failure. the vin was unknown. the failure mileage was approximately 120,000.

Cause code: 6021 - component damaged/cracked, reverse clutch plate replacement reading various forums, these seems to be a problem with all lambada platforms, hundreds if not thousands of transmission failures, creating a major safety concern for myself and the public. gm needs to replace these trannys with a new more durable/reliable design before someone is seriously injured or killed, its only a matter of time. please confront gm with these complaints...thx http://townhall-talk.edmunds.com/webx/.f215073?displayrecent. *tr

Water leaks in car when it rains, over the past 4yrs my car has been back to dealership for same problem, in which they fixed at no charge to myself and once again i am experience the same leak when it rains. they safety concerns are very big because of all the electrical wires that the water may be coming in contact with, including the air bags. i have contacted dealership and gmc and they both say that i am responsible for the repairs this time. the problem is their design and i know that they are aware of it because of the many,many,many other customers having the exact same problem. something must be done. *tr

Known issue with this vehicle- was never notified of defect. significant water leak from somewhere in roof into passenger compartment at a posts and into dash area. *tr

Tl*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.

Vehicle leaks water when it rains onto driver and front passenger. water leaks into airbags and visors. after rains, vehicle will not turn off, even with key removed. vehicle rolls significantly while in park or when in gear. transmission skips and slips. *tr

I bought the car in late 2008, it has leak every since the first time it rained. i have taken to the dealer more than a few times. the only solution they give me is to seal shut the sunroof. the dealer believe that is the problem. it used to leak from the sunroof but now every time it rains it leaks and a lot and from all over the place. it has severe water damage and the car smells awful because it is wet all the time. my car only has 77,000 miles and i was hoping it will last me a while but now i'm not sure. the vehicle has manufacture defective roof drains. *js

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. *tr

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. *tr

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. *tr

Tl*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 *nj updated 04/06/09. *jb

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. *tr

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. *tr

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. *tr

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. *tr

My 2008 gmc acadia slt2 model has water leaking into the passenger cabin. the water leaks are coming from the seat belt retraction area on the pillars leading down from the roof and also on the pillars at the front windshield where the airbags are located. i also have water soaking the front driver and passenger rugs, it appears water is running down the fire wall from the front possibly down the pillars. the rood headliner is getting wet at each spot where the roof pillars meet the headliner. i am quite concerned about water affecting the electronics, fuse box, airbag deployment and i am concerned about mold. i have noticed that the brake pedal squeaks when i depress it and i attribute this to the water hitting areas it should not be. i purchased this car with 1,275 miles on it as a certified pre owned vehicle on 12/12/07 and i am bringing it back to the dealer tomorrow 12/26/07 to see what they plan on doing to remedy same. i have read of various other experiences with water leaks affecting the fuse box and electronics for overall operation of the vehicle. i feel unsafe. i've read something about a tsb # 07-08-57-002a but i do not see it listed on your site, i will look further. *tr
