I travel with a Lexus es 350 and each time I put on the A/C and drove a little distance it usually triggers the traction control and check engine light on and also sometimes doesn’t detect the remote for tumb starting but once I hit the remote on an object the green light for starting comes up.
Pls kindly clear the air on this.. Thanks
