2022 Malibu Premier 2.0 turbo. Does anyone know why my tack reads idle speed at 1400 rpm?MMy Autel reads 8xx for rpm.
With only 230 miles on it and going in for repair.

If your engine is fully warmed up and scanner is showing 700-850ish and tach reads 1400 that is definitely a gauge error. There are a bunch of 2022 bulletins for gauge issues but they usually say gauge dropout. Hopefully the dealer has seen it and can update whatever needs to be updated. Let us know what they find!

So the dealer said the gauge cluster lost communication. They ordered a new gauge cluster and will call to replace when the parts are in.
