REPLACED A PROPELLOR SHAFT AT 59,000 MILES 8/23/2025. PAID $859.00. UNAWARE THIS COULD HAVE BEEN REPAIRED AND COVORERD BY A MANUFACTURERS WARRANTEE. SIX MONTHS LATER MY MECHANIC(1) AND CAR DEALER(2) RECOMMEND A BODY CONTROL MODULE AND POSSIBLE REAR DIFFERENTIAL REPLACEMENT ESTIMATED BETWEEN $1500-$3500. THIS VEHICLE STILL HAS LESS THAN 69000. THIS HAS BEEN A HARDSHIP AFTER PURCHASING A NEWER VEHICLE SO I COULD HAVE FEWER REPAIRS TO MY BUDGET.

On 2/18/23 our equinox failed to go into park. We couldn’t shut the car off, nor start it back up. Everything electrical was on basically idle mode. ESC - brake control module came across the dash. The dash also kept saying to put the car in park. It wouldn’t go into park. We called for a tow truck to have it taken back to the dealership. When it was taken to the dealership the car was ON. It still wouldn’t shut off. As of 2/21/23 they want $550 for a diagnostics and a dead battery. Of course my battery would die after 2 days of sitting and being on. This is a major safety issue with GM and chevy vehicles. We have 48,653 miles so we’re out of warranty. The dealership didn’t bother to call and ask what happened nor want to listen to what occurred.

Chevy Equinox turned off while in the turn lane. Car would not turn back on. No warning was shown prior to the incident but now there is a solid check engine light. upon googling it seems other chevy's have a fuel pump flow issue causing cars to stall and not turn on. chevy upon inquiring if our equinox has a recall they said no even though other 2021 equinox's have this issue. i believe this is a safety issue, if it is a fuel pump issue how do we know it can't cause the engines to catch fire from improper fueling. this needs to be looked into.

It was a dark cold (minus 18) morning driving to work. All of the sudden a warning came on. The engine power is reduced mode came on and I went from highway speed to 30 mph instantly. I barely got home. I was terrified and the car would hardly go. Very dangerous. After much research because no dealer could get us in ( three week wait) we figured out what was causing it. Code P0234 turbocharge overboost. The dealer said I was safe to drive it. Still reduced power. After one week it warmed up to 17 degrees and the check engine light came off. I still have reduced engine power. New turbocharge feature for the 1.5 lt equinox. This should have been tested in cold climates. We regularly have 20 below temps and it’s a brand name car. I see a recall coming.

I feel the transmission is defective on this car. There are only 800+ miles on the car. In the morning I pulled the car out of the garage and the car did not feel smooth. I said that seemed awfully odd. I drove the car but nothing else happened. In the evening I parked the car in a parking lot up against a curb and a fence. I turned the engine off and placed it in park and I am positive about that. All of a sudden the car lurched forward jumped the curb knocked the fence down and stopped against a tree. Needless to say I was traumatized.
