“Stabilty light came on, loss of power, check engine light, rough shifting into 2 gear. It has been down for 2 years. And not fixed yet, chevy dealership does not know what tpo do. There needs tobe a recall on the flex fuel. We were going down I-20 when all this happened. There was nearly an accident”
NHTSA complaint #11297438, filed 2020-01, 85,000 miles“Stability control warning pops up on display, resulting in a severe power reduction. This causes the vehicle speed to drop from 70 MPH to around 35mph instantly. This nearly resulted in a rear end collision, of course. This was only prevented by a very alert driver behind me. I read that this is a very common issue with GM vehicles yet nothing is being done by GM to provide a safety recall”
NHTSA complaint #11114692, filed 2018-07, 116,000 miles“Total engine loss at highway speed, Chevrolet want to replace the engine, but as I read all these complaint about engine and oil and afm.
