Car shuts off while driving
My 2006 Chevy Malibu Maxx will shut off only on
hot days in the summer. The engine will shut off
ONLY when I am driving never when idling. There
are no codes and the check engine light is off. I
have taken it to multiple mechanics and all they tell
me is that my car is in great condition and runs
great. Sometimes it will shut off 4 or 5 times in one
sitting. It struggles to start back up when this
happens. I know when it will shut off because right
before it happens, my car will beep a few times,
the check engine light will flash as well as the
traction control light with a line through it. My car
will also shudder and shake before it shuts off. My
mechanic boyfriend says the PCV valve is bad and
I have a few vacuum leaks, could these cause my
car to shut off? Or what else should I check?
