[SOLVED]Abs light, hill assist fault light, power steering light, no parking assist light issue

[Biggsy]

2017 GT with 29k miles…Hoping some of you guys can help me with something that has never happened before…

30 min into driving I start getting all these service lights. I first get “advance track off” then “power steering fault asssist service” followed by “hill assist service”. ABS, traction control, airbag light all come on. Car is still driving fine. I come to a red light and restart the car. Lights go off but those warning boxes flash again. Next thing I lose power steering and Hill assist doesn’t work. When parking just now, parking assist service flashes on the dash and all of a sudden the sensors don’t work. I drove the car this morning and every was fine.

What could it be? Have my first track day of the year on the 2nd so I’m hoping to have it resolved by then.

Thanks for any help

Had the hill assist/back-up cam/reverse light issue on my 2020 from the day I drove it home. There was an active TSB on it and a software update fixed it in less than 30 minutes at the dealer.

I had a similar issue on a 2017, it ended up being the battery.

I hope its simple.

I have gone through threads and asked on Facebook groups. some stated it is caused by the rear hub and had that replaced along with the abs retainer ring(or what ever its called). For some it was the ring that snapped.

Unfortunately nothing electronically is simple on today’s cars. That’s why we cannot give you the answer you are looking for. It “could” be a lot of different things. Only your dealer will know for sure.

Try this link - sounds like the rear thrust washer failure - common with the S550’s:

Yup that’s the ring I was talking about. I know it’s quick fix and under warranty. Dropped the car off yesterday morning and was told I got at least 19 cars ahead of me. I have a track day Monday but I don’t think I’ll make it.

Find out what the service manager’s favorite adult beverage is and leave one on his desk with a note asking him to get you done ASAP. Good luck.

Just got a video from the tech and sure enough it was the broken washer. Car is ready to go for my track day on Monday!

If you live in the DMV area, Koons Silver Spring is top notch!

Good to hear it has been resolved and the turnaround was quicker than expected. Best of luck!

So did you run a scanner on it yet to see what code faults it has?

Did I run a scanner? No. I just saw the messages on the dash. There was no check engine light.
