    Engine light. Codes, P146B, P0114, C2B00 @ 64000 miles and the emission purge pump has failed, ECU, purge solenoid. I see an extended warranty has gone out for the same year Envision. As this is the same P/N for this brand and same problems, (I.E. 2020-2022 Encore extended warranty) will this be covered anytime in the future?

    Engine power reduced all of a sudden on a highway. Turbo went out at less than 45k miles. Turbo was replaced by GM and was told this will occur every 2 years by the dealership. Very unsafe especially driving at highway speeds.

    I was driving in heavy traffic when I got a reduced power message. There was no where for me to go to get out of the traffic. This is the second time I've had this issue. I have already replaced the entire turbo several months ago. I took it to the dealer then. They attempted to fix it with just replacing part of it. It didn't fix. The cost to fix it at the dealer was more than I could afford so I took it to a different shop. All together it cost around $2000. Now it's…

    Three nuts snapped, which secure the front muffler to the length of the exhaust system. The engine side of the exhaust pipe became disconnected and dragged along road, which occurred while driving the vehicle on a residential road. Steering was not impacted, however the pipe would have eventually come completely free, without driving directly to an auto-body repair shop.
