TCS / ABS warnings
I'm new to the forums and hope this is the right place to pose my question.
2017 Jeep Wrangler Unlimited Sport S
2.5" lift installed back in 2018
-- including Sway Bars and Track bars
Recently, at very low speeds like pulling into a parking spot or doing a U-turn on dry/smooth surface, the ABS and TCS warning lights will come on. I've seem them come on dirt and places i'd expect but this is new, i.e. on dry/smooth road. It seems to be happening more frequently and will persist even through engine restarts. The lights will go out on their own after driving straight for several feet.
• In March, I had the rear rotors & pads were replaced.
• In May, I got a new set of tires.
The issue with TCS/ABS is just started happening in the last few weeks.
The shop recommendation I got was to replace a speed sensor though I failed to clarify which wheel was affected.
Does this seem a reasonable first step? Seems like it could a serious issue if the warning lights stay on but in my case, they've been going off on their own after a short distance.
Should I got back to the shop that installed the new brakes? or the shop then installed the tires?
Thanks in advance.

Welcome to JK Forum .. Good group, friendly and knowledgeable.. as for the shop; which do you feel is more knowledgeable? The shop doing the brakes vs the Tires? Wheel speed sensors can cause and the shop that did the brakes would be more likely to be working in that area of your Jeep. The tire installer would not be in that area unless they hit the wiring lifting your rig. Do a visual inspection for wires to the wheel speed sensors being broken pinched and or the sensor itself not being in correct location. Get on Utube and look for videos.
