In January my front left end was clipped by a school bus. The car was in a certified Lexus body shop for about 5 weeks. I got the car back on a Friday afternoon and within 30 minutes the Check Engine and VSC lights turned on and the display said VSC Off. I took it back to the body shop they got the lights off and ran it saying it was not wreck related. The ligths came back on 24 hours later after I picked it up. Then they stayed on for a while. The other day it turned off for a day then came back on the next day. I got Autozone to run the codes while they were on and they said P1349 and P1354. The lights are currently off but will probably come back on. I am looking for suggestions as to what is really wrong and what I need to do.
