Check engine light

[Nawlinssaints1]

Check engine light on. Noticed that the MDS is not working. I am not a fan of this system on my truck. Has anyone had this problem. Truck has extended warranty so not worried. But darn this extended warranty has gotten a work out. Lastly exhaust leaks. I just had the truck in the shop for this issue. The headers have been replaced and new bolts added. Just had it reworked and joint at the collector repaired. What else can it be? Thank you and take care.

You have to get the OBDII port scanned and report on the code(s) before anybody and even make a guess to help you. And you have to post the codes:
Also helps to know trim level and how many miles. MDS smhhhhh.

FYI: Check engine light on means No remote start also.
