2012 Yukon Denali won't try to turn over.

[OR VietVet]

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.

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, 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?

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.

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
