Have you had a lot of rain recently?

 

[edgleason1]

Yes but it has also happened when it was dry and sunny and I was going 35mph on a local street.

Are you sure it said Traction Control On and Park assist on? Those are new to me, usually just states when they are off. Is it old there? Check your Oil level and your Brake fluid level.

Hi all, I currently have the same problem with my 2012 Acadia ... loss of power after the car displays a variety of messages (Traction control off, Traction control on, Stabilitrack needs service, Park Assist on .. then a loss of power and the car will only go 15 mph. This is the 3rd time. The dealer replaced the Vape sensor on the exhaust and cleaned out the engine ($800 in repairs) but still have the problem. They don't know what is wrong and have called GMC direct who should be aware of this problem and they don't know what to suggest.

Arg!! I love my Acadia but I will not endanger my family. Has anyone come up with a fix?

Thanks

I know it's a long shot but have you changed your plugs recently? My '12 SLT did this same thing last year so I took it to an ex-GM Tech who has his own shop. He ran it through diagnostics and said I had one bad spark plug. He replaced the plug and it has been running smoothly ever since. No codes. Good luck.

I meant to ask if it was cold there.

I had the same problem with my 2014. It happened multiple times while driving. Thank goodness no one hit me. I took it in to my local GMC dealership 3 or 4 times. The first time they changed the ECM computer. Took it home and within a week it started happening again. The last time we took it in the mechanic basically said sorry we don’t know what’s wrong with it so here’s your keys. Next day we went and traded it in. I loved that car. We have since got a 2019 SLT Acadia and I hope I didn’t make a mistake in buying another one. I absolutely loved my 2014 and didn’t want to get rid of it. Hopefully whatever the problem that everyone was having has been fixed.

My 2012 GMC Acadia had the Traction Control, Stability Tract Conrol and Engine reduced power come on and just shut the car OFF. So did my neighbors 2012 Acadia. This is a wide spread issue. For both cars to do the same thing within a month of each other right next door. That is too coincidental. I will never buy another Acadia. I have dumped over 3 grand into mine.

I have seen several posts on this condition occurring, where the Engine Power is reduced, and the stabilitrack and traction control go off, and the message is to service both. I have NOT seen a consistent solution to this problem. There have been some that said electrical, the battery, something with the AWD, etc. I have had a local dealer tell me that it is the Throttle Body. This is a serious issue, needing a resolution. Imagine being on the highway, you lose engine power, and a tractor-trailer and other are barreling on behind you. How do you get out of the way? Once pulled over, and letting the car sit for a short while, the car will start and run fine. This is an intermittent problem, that comes unpredictably. Is there an answer? Is it the Throttle Body? I have this cleaned twice, once by the dealer and once by a local mechanic. This is short-term fix evidently. I need something permanent. Someone please advise, and share your success in getting this resolved.

I have had this problem starting about 2 months after buying my vehicle, a 2010 Acadia. Have had it in several times, 3 years later and still not fixed. Now I also have check engine and service wheel monitor system. I wouldn't care about having to keep taking it in for the same problem, if they wouldn't charge me, my deductible fee every time! It is the same thing that they can't figure out. One time they said it was a sensor , but sensor got melted into hub, and drilling hub to get it out,they ruined my hub, and charged me 800 dollars for repairs. I have contacted gmc, and they were no help. I live on 700 dollars a month, I can't drive it,but have to make car payments. I have no money for them to keep guessing! I hate gmc, and will never recommend them!

I have a 2014 GMC Acadia SLT2. Front wheel drive. This issue has been happening for me as well every couple of months out of nowhere, just under normal driving conditions.

The following errors are thrown in the dashboard:

1. "ENGINE POWER IS REDUCED"
2. "SERVICE STABILITRACK"
3. "SERVICE TRACTION CONTROL"
4. Check engine light comes on
5. Traction Control light comes on

My amazon purchased code reader throws two errors:

1. P1682 - Metering Oil Pump Malfunction
2. P0689 - Engine control (EC) relay - sense circuit low

My car basically loses power and I have to pull over to a complete stop. Once I turn off the car, then turn it back on, everything runs fine. The check engine light stays on, but other than that you would never know there was a problem.

I've taken it into the GMC service department and they don't know what's wrong with it.

Did you actually pay the dealer to diagnose the problem?

 

[speleos]

Something appears incorrect in what the Amazon scanner is telling you. Look up P1682 on the 'net and you'll understand why. While you're doing that, search for the other code and read the troubleshooting tips posted by OBDII experts.

I was prepared to pay them. I had unwisely cleared the codes before I took it to the shop. I wanted to see if the check engine light would come back on. The service people couldn't get the light to come back on after driving it for 5 miles so they didn't charge me. They basically didn't even try since they couldn't get the codes to come on, which is probably fair.

I thought the same thing. P1682 doesn't seem to have anything to do with the oil pump.

Maybe the code is correct, but just the mapping to a description is incorrect. I don't know. I don't know much about cars. Since this issue just happened again today I'm going to take it to the service department tomorrow and see what they say. Hopefully they'll be able to get the codes and give an answer. I'm sure they'll find something to tell me needs replacing.

...I'm going to take it to the service department tomorrow and see what they say....

Day 2 - Dropped it at the Cadillac dealer service department in the morning. After a few hours they called me back. They say the Fuse Box needs replaced. $815. I'm gonna bite the bullet and give it a try...

They are known to suffer from water intrusion which can wreak all sorts of havoc on the electrical system.

Day 6 - They replaced the Fuse Box (Block?) on Day 2 and so far so good. Sometimes I'll go months between this issue surfacing though, so only time will tell.

Hey, yall!! We been at this issue for years because we love the Acadia's, right!? Well this is the Avenue I'm headed down next with my 07 basic as all get out trim package.......... I believe it's a grounding issue....... I know everyone is gonna be like, "yeah but this" and "yeah but that"!
Look we've tried all the other this and that stuff already, hundreds of times! All that stuff I really think can be affected by the ground OR effected by something that's effected by ground.
Don't get me wrong, they are not all the same ground issue! GM made these grounds supper corruptible to different problems. Myn was timing chain and engin swap that was put in by either a bad mechanic or one unaware of this Acadia thing........ think about how your problems started........
