While driving the brake pedal suddenly became hard to push making the car unable to slow down. Put car in neutral and managed to get off street into parking lot and coast to a stop. Car would no longer start. Towed to dealership for assessment. Reports of broken vacuum pump pieces and related metal debris found in engine. Dealership recommended engine replacement. Notified GM, they provided a case number and helped discount the full cost of engine replacement down to $6,225.00 which we paid out of pocket (or risk losing the full value of our equity in the vehicle against a replacement).
My vehicle suddenly began giving a message engine power reduced. This happened on a highway that required with a maximum speed of 65 mph. My vehicle reduced speed to under 40mph which may be beneath the minimum speed limit. I took the vehicle to a chevvy dealer who said my transmission was slipping. I took it to AAMCO spent 6000 on repairs only to have the engine power reduced error continue to appear. AAMCO claims they have made all repairs yet the light is still on and my vehicle continues to lose engine power on fast highways (the intended interstate). I called chevy because I had seen similar issues in older models and they refused to accept me rendition of events because my vehicle was not serviced by chevy. I tried to upload a photo of the error message The upload is not working.
2018 Chevrolet Equinox Premier. The engine connecting rod to the #1 piston separated, causing the engine to stop while the vehicle was in motion. The only warning light at the time was the tire pressure monitor system. The incident had no warning. My husband was driving the vehicle. Initially he thought the car blew a tire by the noise, but then the engine stopped/stalled while I was driving. He was able to get to a side road. The vehicle would not start. He smelled burnt rubber and then thought he broke a belt. He pushed the On-star button for roadside assistance. The car was towed to Ferman Chevolet, Adamoo Dr., Brandon, Florida where they inserted a camera scope and confirmed the rod separation. I do not have paperwork except to show they gave me $2500 towards a trade-in. Over the phone they said it would be $1800 to take apart the engine to confirm the separation. The mechanic suspected the engine was scarred as a result. It would cost $12,000 to replace it, or they could talk to the sales side and see if they can let us trade it in on a different car. We traded the vehicle in. I just saw news of another GM recall affecting the 6.2L V8 and thought it odd that the same thing happened to my vehicle, which is not included in the recall. The engine stall caused my husband to stall in the middle of the traffic lane on a side street. Had he not gotten to the side street in time, he would have blocked a traffic lane on a very busy road which could have resulted in a major accident with injuries.
My son was coming home from work 3/26/2025 after 5 pm, when a warning message came on that said "Engine Power Reduced". My son attempted to pull over, however, the brakes did not work. This caused a definite safety risk to my son and others as he could not stop the vehicle. Gratefully, he was on the street and not on the freeway where speeds are higher which could have caused injury or possibly death. He found a clear area to pull over and put the car in park and pushed the start/stop button to turn off the car. The car had to be towed to my home. The car was towed to the repair shop 4/1/2025. There were no previous warning messages regarding the engine or otherwise until the day of the incident. The vehicle is currently in the shop and has been inspected.
This rare equinox has a Turbocharge issue that causes rapid engine power loss, and melting under the manifold and around the fuel injector pipes. The recent recalls do not include this GM made diesel equinox due to its rarity, and small consumer ownership of 506,775 units sold in its lifetime. However, GM has been just as negligent with this diesel 1.6L, as with the other major model lineup. Diesel particulate sensor goes bad every year around installation anniversary (previous recall). Stated every year in purchase anniversary month 10/2021, 10/2022
Good afternoon I hope everyone is well. This complaint I'm filing for Turbocharger/Supercharger A under boost condition (P0299) with my daughters 2018 Chevy Equinox. When you research this error with Chevy/GM vehicles you'll see this impacts all vehicles, but Chevy/GM is only recalling their vehicles from 2022+. I've spoken with numerous auto mechanics throughout the United States, and every auto mechanic has stated this is an issue that impacts all Chevy and GM vehicles. Both Chevy and GM are deceiving everyone and there's a significant issue that requires Chevy and GM should address.

When backing into my drive way moving the gear from d to r the car will jump. This has made it to where I fear to park where I have to reverse. As well as when I started driving down the road the auto stop start kicked on while doing 30 when the car powered back on in the busy intersection the car was clunking I pulled over asap and took a look under the car to make sure nothing was leaking when started back up it went away. It’s very unsafe to have a car that you can’t disable the auto stop feature from coming on as if the intersection was not a safe place for this to happen
