So, I have an 08 is250 awd with 134k miles. Runs great, no issues, just state inspected here in PA.
had the tpms lights come on, one sensor bad, never replaced, light went off after 5 days, still off (just for context)
Last night went to pick up my wife, sat for 45 mins idling, turned off engine, back on 5 mins later. After 2 mins the check engine light, Trac off light and the vsc came on at same time. Have stayed on since.
the car still runs perfectly, has never dipped undee 500rpms in 3 years of ownership. Driving fine, idle good,, brakes ok,, shifting fine..

Tightened gas cap, will get codes pulled at auto zone today.. just looking for some possible insight before getting a list of codes that may be false as I've read the ecu is finicky with glitches

Any help as always would be greatly appreciated
Steve

 

I had the same issue on my 2008 IS350, RWD, a few years ago and again earlier this year. Issue ended up being a bad front wheel hub.

I don’t remember the code(s) the car threw but your issue seems to be identical.
