Limp mode issue in my 2019 Malibu

[ChronoQ]

I could use some advice. My 2019 Malibu 1.4L turbo randomly goes into limp mode, says T/C off, fuel drops to E, then resets hours later, I had no impacts or accidents., so what could this be? a loose wire? I am yet to check it out with a dealer

It sounds like your car might be going into limp mode due to a sensor or boost problem. A common issue with these Malibus is that the turbo outlet hose can come loose at the throttle body, so it's definitely worth checking that. There might also be a faulty pedal position sensor or a loose ground wire leading to those odd readings.

Have you had a chance to scan for any codes yet, even if the check engine light isn't on? That could help pinpoint the issue quickly.

Why haven't you taken it to the dealer yet, especially since it sounds like it could be an electrical or sensor-related issue that might get worse over time?

I haven't scanned for codes yet but will do that ASAP, and I'll check the turbo outlet hose and wiring for any loose connections or damage

I plan to visit the dealer soon, just trying to gather info first and rule out simple fixes like hoses or wiring before bringing it in

I hope you were able to scan the codes and take a look at the turbo hose and wiring by now. Fingers crossed that it was something simple and you've sorted it out quickly
