2012 Yukon Denali won't try to turn over.

[Kurt Johnson]

Our 2012 Yukon Denali was running perfect. Took it to the detailer and they said it wouldn't start. Battery is charged. Also the rear hatch won't open now. It's almost like the vehicle won't let it start because the computer thinks the car is in gear?

Anyone familiar with this issue. Everything lights on the dash as normal.

Thank you!

Theft deterrent causing problems. Might try taking the battery cables off and wait 1 minute and then touch the cable ends together and reinstall and see what happens. This is just a WAG.

What did you take it to the dealer for? They ought to put a Tech-2l on it and find out what's wrong.

The "detailer," not the dealer! LOL

I know, I shouldn't be on here but can't help myself! Well, did the "detailer" clean the engine bay? Wonder if something got wet???

Sorry. The detailer (car wash detailer) discovered the issue while they had the Yukon. We towed it to a Christian Brothers franchise and they couldn't figure it out because the diagnostic tools they use wouldn't show anything at all. We then towed it to a dealer. They are trying now.

Hope the “detailer” is ready to fork over some cash for repairs… ******* amateurs…

So the rig started when they pulled in to do the detailing and then would not restart to get it outside. This statement is a bit off then," Took it to the detailer and they said it wouldn't start." Made it sound like they never got to do anything to it because it would not start to pull inside.

Does it help to diagnose the issue knowing whether they were able to wash and detail the car?

They washed the car pulled it out of the car wash to vacuum and clean the interior. Presume they turned it off at this point. When they finished detailing the interior it wouldn't start again.

Yes it helps. They are the ones in possession of it and their steps of care can be the difference or maybe not but it can be important what they did while they had it. Common sense.

Yes, as Ron mentioned, they very likely did something (not intentional) that disabled the car. Failures completely unrelated do happen though as Ron and I have both experienced when we had shops! We usually got the bill when it was Mr. Murphy's fault!

Frankly, reading the description of the events, my assumption wouldn't be the detailer did something wrong.

My assumption would be a BCM failure. But in any case, the dealer techs will get it sorted.

Wet connection?

 

[Doubeleive]

if it thinks it is in gear and won't start it would likely be the shift interlock and not anyone's fault, dealer will ding you for about $500 if this is the case. a tech2 would tell you.

 

[Fless]

Would be nice to know if they had the hood open and did anything (wet) in the engine compartment.

Did you ever find out the issue my car is doing the exact same thing after going thru the car wash
