Engine block cracked at 70,000 miles.
Directional signal works only some of the time.
The car is a lemon and should be taken off the market.
A lot of problems with the vehicle and no reason for them.
I have a 2002 Saturn Vue and the same thing has happened to my vehicle. At 74,000 miles my engine block cracked, at 76,000miles the clutch went and now at 78,000 miles my transimission is now gone. Just like you my signal works only some of the time.
