2014 Infiniti q50 RWD Driving on freeway doing 69 MPH chassis control system error popped up on the dash abs and traction control light illuminated as well I stopped at gas station turned the car off for a few minutes and started it and all lights were off drive about 10 miles and all 3 lights came back on. Has anyone ever had this issue?

I would guess one of your wheel speed sensors is malfunctioning. Scan the car for DTCs and post any you find here.

Agree. Likely wheel speed sensor is bad. Scan codes to determine which one.

95% likely to be a speed sensor. I had this happen in November. I was really worried at first. Frustratingly my code reader is too old for this car, so I took it to the dealer stealers for diagnostic and repair. $795 CAN later the rear driver side speed sensor was replaced.... Needless to say I got a new code reader and will replace my own going forward. I was surprised that these sensors are not so cheap - couple of hundred bucks. Good luck.

Yes,,just a few days ago,,I had just installed a different intake coupler/collar,,and that exact chassis system error came on,,I pulled over, popped hood, and one of the intake tubes had come completely out of the coupler, leaving a wide open throttle body,,I reconnected it securely, the light went away,,and no issues since,, over a week),,,

When I had that in my vq37 it was a driver side intake had come loose,only thought is make sure nothing is ajar or disconnected accidentally,and everything you can see or touch under the hood is tight and well connected.

Did they do a TPMS sensor ID registration on the wheel with the new tire?
