Upon entering freeway on ramp, traction control system warning light came on. Temporary knocking sound. Light is still on, manual says it is related to brake system control?

Hello,

9 times out of 10 the problem is a wheel speed sensor that has gone out here is a video to show you how to get the codes so you can see which one the problem is.

if you want to test the sensors by hand this guide will work.

Car hesitates when driving, service traction light comes on and doors are unlocking and locking rapidly. Never know when it is going to happen. Supposed to take it to a repair shop when it does it again and to leave it running so that they can run a diagnostic on it. It only happens when they are closed, so far I have taken very good care of my car since I bought it brand new. Had the 100,000 mile service at around 95,000 miles.I don't want to go through what everyone else has gone through with multiple trips and lengthy stays in the shop to no solution. I work full time and take care of my mother who is entering the late stages of ALS. She depends on my and I really need my car. Please help.

This sounds like you have a BCM that is out and needs to be replaced. Here is the location of the unit you will need to have the unit programmed tot he car by a shop.

Please let us know what you find.
