Have you had a lot of rain recently?
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.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 meant to ask if it was cold there.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.
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.
Did you actually pay the dealer to diagnose the problem?I've taken it into the GMC service department and they don't know what's wrong with it.
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.Did you actually pay the dealer to diagnose the problem?
I thought the same thing. P1682 doesn't seem to have anything to do with the oil pump.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.
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 thought the same thing. P1682 doesn't seem to have anything to do with the oil pump.
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......I'm going to take it to the service department tomorrow and see what they say....
They are known to suffer from water intrusion which can wreak all sorts of havoc on the electrical system.Day 2 - Dropped it at the Cadillac dealer service department in the morning.

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.Day 2 - Dropped it at the Cadillac dealer service department in the morning.

I had this happen yesterday 2/16/2022. I have a chevy Traverse. Traction control turned off, reduced engine power, and I was doing 75 on the hwy. It's very unsafe for this to happen. The mechanic picked it up today and replaced the throttle body. I'll have it back tomorrow so hopefully that's all it needed.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.
