2016 jeep Cherokee check engine light
So I literally just got my car 2016 with 23k miles. So the
check engine light will turn on and the car will ring/jeep and
display "service parking break" service this service that
then just turn back off and be normal again. Yesterday
when I got in and turned it on it wouldnt even start for the
first few minutes. When it finally did start I let off the brake
and all of a sudden it kind of jerked and displayed " put into
park then select disiered gear".. also I was driving down the
highway and all of a sudden the stereo display screen and
my speedometer/dash board EVERYTHING went black and
then came back on. Please help my car place is bs me
around!!!
