The traction control light in my 2013 Isuzu MU-X is coming on from a cold start. The engine wiring harness has been replaced and it’s still doing the same. Now the shop is saying the battery is low, but voltmeter shows 13.8-14 volts when running and I have not had to jump-start the vehicle at all. When light is on it really slams into gear. Have you heard anything like this before?
It could a sensor in the ABS/TCS system; it could perhaps be the computer controlling the electronics. You need to have a diagnostic check done on the car to properly identify the cause of the problem.
