FIXED 2015 CHYS. 200 CAR WON'T GO OVER 30MPH AFTER BATT. DIED

God bless you my brothers and sisters.
Ok so my daughter calls me to tell me her car won't start, car totally dead so i tell her to get a jump starts. She checks gauges and car is charging but it will not go over 30mph. I have been looking this up on google seems to be a common problem but as of yet i haven't found how to fix this.
I just need some info. about this problem i think it's in limp mode but how do i get it out of limp mode? I live in mexico she lives in california so i just need to know if the batt. is causing this and needs to be replaced or maybe clear codes due to bad batt.
Thank you for your help.

Hey gilbert! I think your suspicions about some kind of forced limp mode are right on. Low battery voltage does all sorts of crazy stuff to modules.

This may sound silly, but I think she should try a soft reset first, before going much further. Disconnect both cables, short them together, leave them for awhile, then come back and try again. It's free, simple, and stands a chance of working!

God bless you my brother.
Thank you very much for your help I will let my daughter know and pray that it works.

Being a drive-by-wire, an accelerator pedal position relearn may be needed. I think, you can do it with a key on/off sequence, if you don't have a scanner. I don't recall for sure, but it is something like: Key on. Key off. Key on. After 30 seconds, depress accelerator.

God bless you my brothers and sisters.
Thank you very much for your help my brothers i told my daughter to get the batt. charged and do the soft reset and it's all good now. Car is running as it should, again thank you for your help.

Hey, great to hear! Thanks for the update, sir.
