Surprise Yellow Light Show - G35X SES Lights

[Feb72]

Hi everybody, My 2005 G35X (90,000) is putting on a light show. It happened all at once. Let me explain. Three days ago it was snowy and slushy here in Chicagoland. My venerable QX4 usually takes care of things in bad weather, but it was having its SERVICE ENGINE SOON issued handled that day.

While driving on city streets all of a sudden, the VCD OFF, SLIP and SERVICE ENGINE SOON lights came on. No discernible difference in the engine performance, and I did not get into a situation that would cause the wheels to slip. It sat in the garage for the past two days, but this morninig the lights warning lights came right on, and the engine was a little hard-starting.

I've had two Q45s (91 and 94) and had a little relay trouble for the traction control, a very simple and inexpensive fix. Any thoughts?

Thanks, Feb72

have it scanned and figure out why the check engine light is coming on. I had a similar issue with my 04' coupe with the VDC, SLIP, and SES lights where they would come on randomly. checked for codes and turned out I had 1) a bad wheel sensor ( I was also experiencing an intermittent "abs" light on the dash), and 2) the throttle body needed to be replaced. Had them both done under my 30 day buyers warranty and the problem has yet to come back. that was back in December.

Thanks for the help! I know how crummy those SES lights can be from my Qx4. Serviced three different times as various components of the emission contol systmes would fail. Of course, nothing happened until 240,000! Never has a SES glimmer on the Q45s through 280,000 combined miles.
