I have had a bad sensor indicating low tire pressure on one of my tires for about two years. I had new tires put on and the low tire sensor came on and has been on ever since. More recently I have also had a sensor warning light going off for my lift gate that was difficult to stop and I have had the car horn going off randomly to serve as an alarm without good reason when the keys were on a table away from me. Now this past weekend I received an Service Advancetrac ABS warning light and Brake Service warning light. My car is running fine and my brakes are in good shape. When I took the car into the repair shop they told me based upon the service codes I needed to replace the Advancetrac module and have it reprogrammed. Should I be hesitant to do this (given that it will be near a grand for the repair)? Is it possible or even probable that all these issues are electrical and are related and may not require the replacement of the Advancetrac module?
