"Service Engine Soon" light comes on--& occasionally off. Engine has under 3K miles. Perhaps it's a computer-chip problem? Dealer=100 miles away. Concern=if I drive 100 miles, it'll blow up. This account may be incomprehensible but here goes.
1.) Approx 2K miles "Service Engine" light appears; local mechanic checks engine & resets light (to off).
2.) Soonishly, "Service.." light on. Then "Service" vanishes--when I scrape a door. Door-scrape repaired. Now "Service engine soon" is baaack.
Wrench symbol came on v, soon after purchase. Took to dealer. Dealer reassurance=light there as gentle reminder that eventually--many miles in future-- there's oil change. In other words dealer didn't fix it.
