Traction control triggering on dry road at constant speed.

[Zooks527]

Good day, all.

Had an interesting situation on Sunday. Coming back home after a run to the store and the traction control in my 2019 GT kept coming on. At all of the times it happened, I was running at a steady speed (~57 mph) in 5th gear on a straight, dry and level road on a dry, sunny day. The car would shudder as the TC pulled the throttle on and off, with the traction control light coming on every time it happened (perhaps 5 time for 5 seconds each over the course of a half mile or so). Tire pressures correct on all 4 corners. I've been stuck at home for the last few days, so I haven't used the car since then.

Anyone seen anything like this in the past? Any thoughts on what I can look for?

Thanks!

not sure if these cars have a vehicle speed sensor but maybe one went bad. just saying this happened on my infiniti the rear wheel speed sensor went bad and had this same symptom triggering traction control light and awd malfunction.

Speed sensor dirty or going bad.

Well, hopefully it repeats. It's due into the dealer for it's one year oil change in a week or two, so with luck I can get it to repeat for them.
