2021 Chevrolet Equinox engine problems

Filed Sep 13, 2026 · Engine, Fuel system · MD · crash

I've been having issues since the beginning of 2026. It's saying my car has no recalls but I've found that is does on a part that's been complained about by others. I've had the car repaired multiple times updating the fuel injectors and spark plugs but still the same error codes. Yet and still the check engine light continues to come on. So I looked and found out it maybe the fuel pump after all . I'm constantly refueling at least 3 times a week and also the errors come up inside the chevrolet app as well. This has been frustrating to say the least I hope the dealership repairs this issue without me having to take it back for more repairs.

I was driving in GA and my low engine power light came on and I lost complete ability to brake. The brake pedal was hard and would not go down. I towed my car to Jim Ellis Chevrolet in Atlanta. They called a few days later and told me I needed extensive engine repairs that would cost over $5,000 but GM would take care of some of it. I paid $1980.00. I went to pick up my car and was nervous because I lost brakes on a highway and was afraid. I asked them if they were sure everything was repaired and I would be safe and they told me it was tested extensively and driven and all was good. I drove around 2 hours after leaving and my engine light came on and my brakes failed again going 70 miles an hour surrounded by semis. I called Jim Ellis and they told me to tow it to Walter Jackson who told me it was a vacuum pump that they would have had to remove during the repairs. In addition there is a class action against GM about these pumps for my year and make of car. I have asked for a refund from Jim Ellis contacting ownership, GM, Service Team and no one will respond to my calls or emails. I filed a customer complaint with GM and they are accepting zero responsibility as well. I paid thousands of dollars between both repairs and rental cars and the least I would like for them putting my life and others around me at risk on a freeway is my money back.

The check engine light came on and the engine lowered performance because the intercooler froze and cracked. Despite there being a service update to stop that from happening, we were never informed of the update from Chevy, only once it had happened did they tell us about the update and included it in the repair cost.
