Consumer Description

BURNS OIL, WHICH GM WILL COVER TO FIX BUT WILL NOT COVER THE ISSUES THAT HAPPENS WHEN OIL IS BURNT AND WHAT IT CAUSED. HAD TO REPLACE EXHAUST MANIFOLD, O2 SENSOR, CATALYTIC CONVERTER AND CAM SHAFT SENORS; THESE I HAD TO PAY FOR OUT OF POCKET. NOT SURE EXACTLY WHEN IT HAPPENED BUT WAS MIDDLE OF 2019. WENT TO GMC ABOUT HOW TO GET RESOLVED ON AN ISSUE THAT THEY CAUSED THAT I HAD TO PAY FOR, WHICH FIRST RESULTED IN A 1 YR ENGINE WARRANTY WHICH THEY PULLED WITH OUT MY KNOWLEDGE, THEN AFTER A COMPLAINT TO THE BBB THE BEST THEY COULD OFFER WAS A $1000 COUPON FOR A NEW CAR. GM SHOULD COVER THOSE OTHER ISSUES SINCE ITS AN ISSUE THEY KNOW AND FIXED.
