This is my first post, and after searching, couldn't find anything on this topic, but am new to the forum, so please bare with me. I purchased my 2007 Acadia, pre-owned with low miles, in March of 2008. I have really enjoyed the vehicle, as it is fully loaded. Considering all the features, it is really an amazing machine. It now has 42,000 miles on it, and several issues have been fixed with no recurence. However, the other night, I returned home from the store and noticed that the engine kept running after I turned off the ignition and removed the key. It sputtered for a little while and then quit. I didn't think it was a big deal, and turned in for the night. The next morning, the power locks didn't work, and I had to open the door lock manually. I put the key in the ignition and the there was no power except for a clicking noise under the hood. Also, I couldn't turn the key back to the position to be removed, so the key was stuck in the ignition. I Called the GMC dealer that I take it to for service and they said to jump it or tow it in. After jumping it, it started right up as if nothing was wrong. After checking it out, the service department said that they could not find anything wrong. The same thing happened again night before last, and it is now back at the dealer. I Told them to keep it until they figure it out. Additional info: It has a sunroof and I had the leak fixed a few months ago under the recall, but now, after recent heavy rain, it is leaking worse than before. Could the water be shorting something out, as the starting problem didn't happen until all the rain? Has anyone else experienced this type of problem ???

Just your luck I had the same problem last week. The same thing happened to me just as you wrote. Did you read my mind? The solution according to SM was a factory defect. A leak where the cowl and windshield come together it is tack welding at the factory and then sealed at the factory. On mine the cowl wasn't sealed at the factory and after days of rain sometime heavy and sometime light; after I turned off the engine and removed the key it continued to run bothe times I used the car that day. The next morning nothing, I did have some clicking noise as the circuits tried to wakeup. If you are not covered under any warrenty you might want to purchase a starter box and keep it in your car and if your park outside a cover.

Thanks for your reply, and I am sorry you are having the same problem. What you said makes sense. Unfortunatley, I have no garage or carport. I would prefer not to have to work around the problem by carrying a starter box all the time. I am going to get the roof leak fixed, and will look into having the cowl sealed after market (if possible). The warranty is, of course, expired. Otherwise, I guess I will have to carry a starter box. Not a bad idea to have one handy anyway.

Well that water leak is causing a problem with the electrical system; there are threads here that discuss the water leaks and the associated problems that occur from it. Be tough with your dealer

 

[speleos]

..... Be tough with your dealer

In a sense, I agree with jsimms. Don't be tough on your dealer, though - they are the folks you need to know so they can help you. Hammer on GMC and the General (GM), himself - they can give the OKs needed for the dealer to repair an out-of-warranty vehicle that shows late symptoms of original manufacturing defects.

[RMcKay]

I am conviced that the water leak is the source of the problem, and the dealer needs to fix the leak that they were supposed to fix for the recall, and not at my expense. In addition, they need to replace any damage caused by the leak at their expense. I am going to try to get them to do this, and I if have a problem, I will contact GM dirtectly.

Although I didn't have the electrical problems, I had this leak & the repair has made my Acadia watertight. Maybe you ARE having the electrical problems listed in the TSB...

I have this same problem on a 2008 Acadia with 114,000 miles. No warranty. Car running after turned off, key removed. Also, battery being drained while car completely off to the point it won't even jump start. Already replaced alternator. I also have water in my passenger side carpet, so it sounds very similar to all the conditions mentioned in this post. I took to dealer and they said the issues are due to me needing a new Powertrain Control Module. ~$650 fix. When I search this forum, I see few other problems with the PCM. Anybody else have experience with these issues?

I would print off the topic above yours and take it in to the dealer; I've done that in the past with great success. This is a known issue so they should work with you on the cost

Hi Brandon,

Thanks for your reply on my post.

My VIN is 1GKER23778J2xxxx

Any help you can provide would be most appreciated. I would not quite call our experience with our 08 Acadia a lemon, but it is getting close. We have had a lot of problems with this car and from what I read, we are not alone.

Thanks again,

Kevin

 

[speleos]

doveldog, you should send your info to Customer Service using email or private message.

 

[jaredmwright]

doveldog I was in the same position as you about a week ago and have about 90K miles on my 2007. I had the same symptoms, car would not shut off and battery was draining overnight and I could hear a noise under the hood near the rear of the engine while off. I pinpointed it to water getting on the fuse box on the passenger side and shorting out connections. See the thread at the URL below for my pictures and description to repair. It should only take about 2 hours and you should be out of the woods for zero cost out of pocket other than RTV.

Good luck, GM should really step up about these water leaks.

Jared

 

[doveldog]

Thanks Jared for taking the time to help me out. You have shown much more concern than the dealer has. I will post an update once resolved so others can be helped as well.

I am also having this exact same problem. Last night when we took key out of the ignition the car continued to run for 10 to 15 seconds after even opening my door. I also noticed a slight dampness on the passanger side by ceiling and door frame last week. I attempted to start the car this morning and it wouldn't start just a clicking noise. Thought it might be the battery so I tried jumping it and when I did one of the battery terminals were sparking when doing so. So to no avail the car is still sitting in my parking lot at work. We have had sooo many issues with this vehicle that I am ready to drive it off a cliff! It sounds to me like these are defintely manufacturing issues.Transmission completely failed in march 2012. Replced under warranty. After replacement had to take the car to the dealership 6 times and having them tear apart the new transmission saying they cant figure out why the car is shaking while shifting into 2nd gear everytime you accellerate. We decided to take it to a different dealer since the other couldn't figure it out. they decided that they thought it was the ignition coils and had them replaced not even a month ago. We are still experiencing shifting issues with 2nd gear and the transmission was replaced not even a year ago. Obviously the coils were not the problem either because it continues to shake while shifting into 2nd. GM used to make good vehicles this has defintely been my worst experience with a vehicle ever!! :angryfire:

Your sunroof is leaking on to the fuse box. Whether its a clogged or disconnected drain tube, it needs to be taken apart and fixed. Things that are corroded will need replacement. Wet thing will need to be allowed to dry.

What year? 2007?

 

[martin823]

2008 I'm just beyond tired of the issues that no one can seem to resolve with this vehicle.

I have a 2008 Acadia with 172,000 mi. For the last couple of years, if I backed out of my driveway while turning (after a rain storm) water would come out of the headliner at the windshield. It never affected anything so I just ignored it. Lately the car has has a mildew odor that I couldn't figure out. Yesterday my wife went to start it and nothing. Battery dead. I used jumper cables to charge the battery off my other car and it started fine. When I shut off the ignition the engine ran for a few seconds and then sputtered for around 30 sec. I tried this numerous times with the same results. I found this thread and realized that the drain tube from the passenger side of the sunroof gutter was clogged. I felt the passenger side carpet and it was wet. I removed the two keepers from the left and right side of the glove compartment (just twist to the left and pull towards you). This allowed me to access the fuse panel behind and under it. I saw moisture and a bit of rain water laying in the pan of the fuse panel. I left the glove compartment open, removed the floor mat, opened the windows and let it dry all day. I watched this video on Youtube (search "Stopped up sunroof drains" on Youtube) which shows how the drain tubes are routed. Not exactly the same on the Acadia as they actually terminate out of sight behind eh plastic wheel well cover.

I then took my fairly large air compressor and cranked it up to 110 p.s.i. I sponged out any ponding water at the clogged sunroof gutter drain. I used a dusting nozzle with a rubber tip and inserted the tip into the opening. My wife stood next to the passenger side front wheel and watched. In two seconds after the air injection a lot of water came rushing out of the wheel well area. After this I filled up a water bottle and dumped it into the gutter. It drained fairly rapidly onto the driveway. Tested the driver side tube the same way and it was not clogged so it drained pretty fast.

I park under a tree so I assume that 7 years of pollen, etc. accumulated in the tube and clogged it. While I had the sunroof closed on a sunny day I noticed gaps where light was coming in at the corners. I pushed the suroof forard with my hand and the gap closed. Obviously not a tight seal.

Anyway, saved a few hundred bucks (maybe $1000) by not taking it to the dealer. If you don't have an air compressor, maybe your mechanic can blast some air through. If you can modify a can of dust off to seal the opening, maybe that would work as well. Not sure if there is enough pressure though.

I have a 2011, 69,000 miles.

Windshield was replaces a week or 2 ago. Its been raining the last couple days.

Today, when I was leaving work, I made a stop on the way home. My Dinger was going off after I pulled the key, and door was open. I was really confused, trying to figure out what was going on. I stepped out of the vehicle, and realized it was still running. I put the key back in, and turned to ON. I put it in gear and started driving. I stopped and shut if off, and it shut off... started again, and the check engine light was on. Went to the local auto part store, he was really confused. Said it was a fuel sensor stuck open. He couldn't find a fix for it.

I drove home and shut it off, and restarted a few times. Finally the check engine light went off, I shut it off, and it was still running again. After it died, and I restarted it, It said to Service my Battery Charging system, and Traction Control was OFF.

I popped the hood while it was still running, and I heard clicking from around the firewall area.

Sounds like same problems as listed above.

I do not have a Sun Roof..

I believe that the leak was caused by the Service Tech who replaced my windshield. That he didn't properly seal something.

I called the insurance agency, and have to call back during normal business hours...
