2017 Acadia Electrical Issues

Over this past weekend we had several things go on with our 2017 Acadia All-Terrain.

I went to move it from the curb back into our driveway and when I went to set the electric parking brake the "Service Parking Brake" message appeared and the yellow P with the wrench light illuminated. I tried cycling the ignition several times and it wouldn't go away and when I put it in reverse the "Service Rear Camera" message popped up. I waited a few hours later, tried again and the message and light disappeared and I was able to set the parking brake then and the rear camera came on with no issue. We have seen the "Service Rear Camera" message before. In between the first issue with the parking brake and it finally working several hours later I got two emails from OnStar Diagnostics; one about the Antilock Braking System and one about the StabiliTrak.

So far since Saturday we have yet to see another issue with our vehicle and have driven it around town a couple of times. I have scheduled a service call with the dealership and will be taking it in to have it looked at. When I was describing the issues with the service advisor I told him I don't like how this may be an electrical system issue and to please have the tech check out the entire electrical system if they can. The warranty runs out this September for the 3 year part as it was put in service in Sept 2016 as a demo before we bought it last June. My wife really loves this vehicle but has also said if it starts having electrical issues we will trade it in (and take a bath on it at the same time). It only has 14,500 miles on it.

Has anyone else with a 2017 seen similar issues?

Got our Acadia back yesterday evening. When I called about it yesterday afternoon I was told that the tech found the codes for all 4 issues in the computer and he was going to order a new parking brake actuator, stabilitrack module, ABS module, and rear camera module. When he replaced the parking brake actuator suddenly the other three issues fixed themselves. I'm not happy with this as I don't see how replacing just the one actuator all of sudden "fixed" the other seemingly unrelated parts....

The warranty runs out in Sept even though we only have 14,500 miles on it. I'm kicking myself for not purchasing an extended warranty and may end up doing so this summer for the piece of mind. I'm not happy that we've had so many problems with our Acadia since we bought it as a demo back in June of last year. So far we've had both sunroof panels replaced, the key fob security sensor (whatever it's called) replaced since it locked us out of our vehicle and after we got in it wouldn't start as it didn't recognize it, and now the issues that were looked at yesterday. We would trade it in today if we weren't so upside down on it. We didn't pay anywhere near MSRP on it but it has lost so much value that we are negative by quite a bit and the only vehicle I can think of that would possibly be discounted enough would be a full size truck that we don't need. My wife loves her Acadia too and understands my concerns but I think her loyalty to the vehicle is clouding what I am hoping won't happen in the future with a large repair bill.

One fault can often trigger the display of several faults. It's called "cascading faults." With computerized systems, it's sometimes necessary to use the process of elimination to resolve an issue. Seems the tech started with the first - predominant - code and that was the proper fix. Ordering additional parts was just a precaution in case there were other system failures.

Save yourself some grief, buy the factory extended warranty and call it good. You have until the B2B warranty expires.

And get the most deluxe plan available if you expect a lot of warranty 'freebies.'
