Consumer Description

Error code P0128. Engine temp sensor keeps going off and on. Temp gauge drops to 0 and doesn’t read, AC goes out, check engine light comes on, steering assist is reduced drive with care notification comes up. This error code and same issue is all over GM forums. Thousands are experiencing this same issue, having to spend over $1000 to get it fixed. Ridiculous this isn’t a recall yet.
