So, when I accelerate quickly (floor it) the "slip" and "VDC off" lights come on and stay on until I turn the car off. Also, when I turn the car on it will frequently start dialing a phone number from my iphone. I konw I'm not butt dialing - it just does it randomly. Is my car just getting old? It's an '07 G35X with about 115K miles.
Any thoughts?

 

Weird... Mine did that when I did a parking lot drift session when I was new to the car.... Yeah regret that one. It's apparently a yaw sensor going bad. Look around.

 

had this issue, i know it sounds stupid but my brake fluid was low. It got low as the brake pads wore out, the fluid level dropped and those lights you mentioned came on.
check the brake fluid level first, top off if needed, the issue will go away after a restart, if that was the issue.

as for iphone ghost dialing, buy an android device and throw that apple across the road.
if its the car to blame, confirm if it's redialing the last dialed number. if so, may be a steering wheel phone button sticking, you should still chuck the phone though. one less iDevice in the world will only make it a better place.

good luck.

 

LMAO!! Android FTW!

 

Thanks! That seemed to do the trick. (the lights, not my beloved iPhone)
