Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
keep getting check tire pressure and traction active warnings. losing pressure in my tires. also car stalls when taking off from a stop and in stop and go situations. been to gmc dealer 4 times now. still having these problems. Is this a common problem? what can be done about it?
(1) Answer
If your losing pressure in a tire or tires, then the warning light will come on, so that is normal, they just need to figure out if the tires are actually losing air or not. Are they actually losing air or is the warning light coming on for no reason?
Are the ABS and Traction control system warning lights on, and is the system recording any fault codes?
