The vehicle has two problems. The radio works, but there is no sound for the back up warning, turn signals or radio. This problem occurs in the GMC Acadia, Chevrolet traverse and the Buick enclave. The problem is likely the premature failure of the BCM or the amp. When driven in the rain, the power steering fails momentarily and it is very difficult to control the vehicle.

After spending $370.51 at my local GMC dealer for stabilitrak errors resulting in low fuel input into the engine, with a maximum speed allowable at 35 mph, my 2007 GMC Acadia is once again experiencing stabilitrak errors. They generally occur when I roll to a stop at a stopsign or stoplight, but I am very concerned that the transmission will reduce speed when I travel the interstate. My local GMC dealer claimed this problem was caused by a "cam exhaust position sensor fault" and replaced the "cam exhaust position sensor" on 3-20-13 for $370.51. For one week this repair worked and there were no stabilitrak errors. Ten days later, my 2007 GMC Acadia fwd is worse than ever, endangering me at night by shifting suddenly into "stabilitrak error, low fuel input" mode. I am terrified that my GMC dealer will charge me more money to pretend-fix this problem, as they have me coming in for $400-$1,100 repairs every other month now since they want to sell me a new car.

I was driving my car when all of a sudden it wouldn't accelerate above (20mph?). I was forced to park it at an apartment complex and get it towed to the dealer. Now less than 6 months after paying out of pocket for that repair, I am having the same problem.

The car has had electrical and engine problems since we purchased it due to water leaks from a flawed sunroof design. Even after a recall to fix the sunroof to prevent water leaks; it continues to leak and damage electrical and engine systems. This is an ongoing problem and is a widespread concern for the 2007-2008 GMC Acadias. I would like someone to investigate this problem. I believe it is a safety concern because the leaks occur in the area where there are airbags. I think there is a structural defect that may not be able to be repaired and it presents a safety hazard for all who drive these vehicles. Please investigate this problem. Do not let GMC sweep this under the rug!

We were driving and smelled a burning smell coming from the drivers door. The drivers side windows switch, door lock switch would not work. We took it to our mechanic and he determined that the drivers side switch had burned up and melted to the door wiring harness. The switch and harness both had to be replaced.

Vehicle has been serviced 4 times for water leak that dealer can not find. Water that has leaked inside has caused a malfunction in the fuse block. This caused all lights, including headlights to flicker and gauges to read wrong information. Very dangerous and distracting when driving. Could lead to more serious electrical problems if water continues to leak in.

For quite some time, the front right air bag sensor does not sense that there is a passenger sitting in the front right seat. We have had the sensor checked repeatedly at the dealer, and they have not been able to replicate the problem (saying everything is fine). The passengers typically are our children, both of whom are 5'9" tall and weigh 120 to 125 pounds. We usually have to stop the car, turn the car off and then on, and then it works. This past week, the sensor was flashing, and we got a related "service air bag" light on the dashboard. We took it in to the dealer, and have been told it is a $1,000 repair to replace the front right passenger sensor module. This after we have had this item checked multiple times (and have been told that there has been nothing wrong with it), and, after a full extended warranty on the car (which included air bags) has expired. There has been a recall for 2007 GMC Acadias for improper sensors, but our car was not included in the recall. In 'googling' this issue on the internet, we see several complaints on official car sites like edmunds, stating a similar problem for other Acadias. We believe that GMC has known that it has had faulty sensors on their 2007 GMC Acadia models, but did not make their 2007 recall comprehensive enough. We would like for the nhtsb to investigate with GMC how many other 2007 GMC Acadias have been serviced for similar problems. Our car has never been involved in any vehicle crash or accident.

I experienced water leaking and running down the inside of both of the front doors. In addition, the dash lights faded in and out intermittently, the clock loses time, the nav and radio screen blacks out, and the stability trak service light comes on. They "fixed" the water leak by extending the drain hoses on the sunroof. All of the electrical problems were found to be related to the leaks in the sunroof. On Sept. 18the of the same year, I returned the vehicle to have a recall on the sunroof drains performed. I advised that I was still having the same electrical issues. A dimmer switch was ordered. On Feb. 20, 2012 I started my vehicle and heard a faint pinging noise like a dying smoke alarm emitting from the passenger dash area. I took it to a GMC center and was told that water had leaked behind the dash, causing corrosion and a short in the ip fuse box. I had to pay almost $1,000 to have the leak sealed (design flaw) and had to have a new electrical block installed. I called and complained to GM that I should not have to pay for damage that resulted from 1) a poor design and 2) damage that should not have happened since I had taken the vehicle in twice on prior leaks which were supposed to have been fixed. It has been three weeks and I am still getting the run around from GM. Now they claim it wasn't the sunroof leaking, but the door. A leak is a leak and it should have been checked on the prior service visits. Apparently the leaking has been going on for quite sometime. I see that others have had this same bad experience. Here we bailed out a company that won't back up its product.

I am on active duty an active duty military member. While attending a military school, I purchased a new 2007 GMC Acadia from a GMC dealership nearby. After the course, I served a year at a military station in another state, while there, my vehicle was serviced twice for recalls by a GMC service center nearby. One of the recalls was to fix a defect in the sun roof that was causing water leaks. I had the vehicle serviced in 09 while the vehicle was still under warranty just before shipping for a 2 year overseas assignment. At that time, I identified some electrical issues. Soon after my arrival to my overseas assignment, more electrical issues developed along with mystery water leaks that were saturating the carpet and causing mold to grow inside the vehicle. There was no GM service center in that country so I had to live with the leaks and electrical problems. Finally after about a year, I had a minor accident where my tire hit a guard rail doing about 10 mph. All the air bags deployed but there was no other damage to the vehicle. At this point I quit using the vehicle. The seat belts didn't work, the ac and heater didn't work, the left blinker didn't work, the engine would not shut off with the key, the battery box behind the passenger seat kept flooding with water and I had to disconnect a battery cable every time I parked the car to keep the battery from dying. The vehicle was unsafe. I am now stationed in the us and have shipped the vehicle back to the usa. I am now trying to resolve all these issues with a local GM service center but I am being told by that service center that the vehicle is basically totaled with only 60K miles but since it is now out of warranty, I am responsible for the repairs.

Battery completely drains while parked in my garage overnight. There isn't even enough juice to release the rear door lock so I can retrieve jumper cables from the rear storage area of the GMC Acadia.

Water entering interior of the vehicle. Points of entry include: Side air bag openings, foot emergency brake(which is located near vehicle electrical components) shoulder seat belt openings and through dvd screen. This is the second time my vehicle has been service for this complaint. The headliner was removed and repairs have been attempted. My concern are with the damage to air bag output in emergency due to water, electrical component damage such as dvd player and electrical component by emergency brake and also the moisture the interior of the vehicle has been exposed to for mold and mildew.

GM instituted recall campaign #08207: Customer satisfaction - sunroof water leak-install drain tube extensions dated: Aug 27, 2008. Campaign was preceded by numerous tsbs linked to the same type of water leak. After first leak in oct08, brought vehicle in for the recall and experienced 2 subsequent leaks since the initial recall repair as a result of the same condition. Have had mold in the carpet and padding on 2 separate occasions. Have had significant corrosion in one of the 2 main fuse blocks to the point where srvc. Tech at the dealership could not turn vehicle off using the ignition key. Vehicle leaks after driving in rain. Have service invoices stating that dealer performed water tests after each repair and found no leak yet vehicle has leaked after every repair. Have detailed color photos of soaked wires, saturated headliner, mold damage and corroded fuse block. Vehicle was only driven a total of 689 miles from date of the initial leak to date of the third leak. During third leak, water also dripped from vehicle's rear display onto third row seats. I feel that GM knew about this problem from the beginning because their aug08 #08207 recall actually identified VIN breakpoints of the affected vehicles. Instead, GM chose to deal with it on a case-to-case basis and it has become a very serious issue. The consequences of the water damage can and have already been far-reaching and potentially could injure, kill or affect the health of owners of these vehicles. Consider opening defect investigation, order GM to do safety recall to fix problem before someone is seriously injured. This deserves some press.

Several issues with this new 2007 GMC Acadia. Most prevalent is the failure of the gas gauge not reading the gas reading correctly. 1st time noticed and taken for service was 3 mo. Old. The gas gauge reads (E) when I've just filled up the tank. Dealer replaced 02 sensors. 1 mo later experience same issue. Gas gauge reads (E) even when tank is full. Taken back to dealer and this time replace (2) O2 sensors and the "sending unit". 2 days later, with the gas gauge reading at half full, the car lunges forward into another gear on freeway in traffic, and stalls. Cannot turn car on - all warning lights on. Towed to dealer. Now states that I need a whole new gas tank because the "baffle" is broken? still at the dealer and is unresolved. This car is unsafe. Previous issues: Car leaks at the sunroof. Not fixed yet lumbar support broken - somewhat fixed but still not like the new ones on the lot. Lumbar handle fell off - replaced backup sensors fell off of bumper - replaced seat tracks jerk - replaced both driver and pass. Still not smooth but dealer says that's the best they can do.
