Consumer Description

The coolant control valve malfunctioned on this vehichle several times during the course of ownership. It causes the vehichle to run in limp mode. This part was replaced in July 2023 at ~40,000 miles as a result. The part again began to fail in june/july 2025 with a dealer visit and diagnostic in July. This causes a check engine light, reduced milage, reduced acceleration, constant fan running and fails state inspection Google searches indicate this is a very common problem, yet no recall has occured to date. The first repair was in warrantee and now the vehicle is out of warantee. If the part was not covered under the vehicle warrantee, the part and repair would have been covered by the part warantee. Becsuse of the initial powertrain warrantee repair, the part warrantee does not apply. This is clearly a defective design and part that requires recall and replacement at GM cost
