Driving down a hill, car stalls, dash lights cycle on and off. After stopping car, lights continue to blink on and off, the starter doesn't work. After a minute or two of turning the key on and off, reversing the key, moving the gear shift lever from park to one and back again, the car starts and everything appears normal--until the next time.
instrument panel lights flash on and off--car won't start. on 2002 Oldsmobile Intrigue
My car did the same thing! After taking it to a repair shop SEVERAL times (because it never malfunctioned for them) I ended up having my ignition/starter replaced. I haven't had the problem since, maybe try looking into that?
