Power/Transmission Loss cruising at 50...

[Dennis]

2020 ST. 70K miles.

This is very similar to the hard acceleration/sudden lane change issue I have had and can recreate but the cause was different.

I was driving a steady ~50mph on a slight uphill grade multi lane highway. (PCH). I heard a "rustling" noise from under the car and then the transmission went to neutral and revving the engine only sorta worked. I luckily coasted to the side and restarted the car and all was well. I checked ForscanLite and there were NO error messages.

My GUESS is that I ran over something weird and it freaked out the computer. However, the rustling noise almost seemed too "slow" to be something being run over at 50mph.

Ugh. I miss old cars that would just keep running until something would tear up the old fashioned way

Thanks for any thoughts!

Dennis.

Hopefully just a one time occurrence. If it happens again or throws a code, I’d be worried, otherwise I wouldn’t worry about it too much. What is this “sudden lane change issue”?

Check your transmission fluid, these cars are notoriously under filled from the factory. Also, I know you’re problem, combined with low tranny fluid, when you’re at highway speed the car is in 9th or 10th gear, when you go WOT, it has to drop like 4 or 5 gears, so it hesitates and loses power a bit. Sport mode and correct tranny fluid level fixed this for me.
