Mass MIL lights -2011 MKX AWD

[A.N.]

So here's something new. Over the winter I had cracked the upper bumper cover, lower valence and driver's front fender liner hitting a snow windrow. It was fine for the rest of the winter and my plan was to replace it myself in the spring, fast forward to moday. The weather has been nice here so I decided to tackle the project. I had a local autobody shop order and paint a new bumper cover, I bought the valence and liner to install. (FYI apparently there is a core charge on the bumper cover, that was a new one for me)

I took the bumper off and dissambled it all so I could replace what was cracked. While waiting for the autobody shop, I pulled the MKX out of the garage and on to the driveway to wash it, with the bumper cover off. Washed it off and when I went to put it back into the garage it wouldn't start. Pushing the "push to start" everything looks normal , except it won't turn over. (You can hear the fuel pump charge, or whatever that noise is). Putting the vehicle into accesory power, not just the radio mode, but the mode where you can turn the fan on and the menus light up but the vehicle isn't running. That is when the MIL lights come on, not when trying to start it (brake pedal depressed) MIL lights include;

-Starting System Fault

-Coolant Overtemperature (it isn't)

-engine oil Low (not)

-Fuel low (it isn't)

-Stability faul

-AWD

-Collision Assist

 

When I washed it, I didn't spray the hose directly on any engine components or exposed parts where the bumper cover was supposed to be. (some water probably dripped onto the radar sensor that sits in front of the rad, but thats it).

I've tried disconnecting the battery, placing key fob into the slot in the cargo compartnent and jump starting it. The new bumper cover is back on and everything is the way it should be, and still won't start 2 days later. I am basically at the point where I am going to tow it to the dealer. Any thing else I should try before I tow it? Thanks.

Not sure how the 2011 displays work, but with older cars, it was pretty standard to turn on certain check lights, with KEY ON ENGINE OFF, which would then go out one by one as the functionality was verified KEY ON ENGINE RUNNING. If there is indeed a problem here, with so many errors showing up, the BCM and/or PCM are likely to be involved. I assume you have checked the underhood and passenger compartment fuseboxes already? That's where I'd start. Also, did you check for exposed wiring in the bumper area? Could have caused a short with the wash water. OR it could just be a problem with the pushbutton start, happens sometimes.

So the dealer diagnosis is a bad PCM, won't be here until Tuesday. At least I have a free rental through warranty and its a MKC. Not a huge fan so far but my wife loves it.

I guess they ran out of Hyundai Accents to rent Hope the PCM replacement fixes the issue!
