That being said, we all have known of (or owned) vehicles that seem to survive for many decades, having been mollycoddled and maintained by gentle, loving owners until they become something of an oddity, like an aged person who is still living and functioning well for years after all of his or her children have died of old age.

Thinking about a vehicle steering/suspension system, we must start where the tires contact the road. If this tire–to-road contact is not correct, then the ride quality suffers and the vehicle is hard to control.
We have to understand the code set criteria, and not just the inferred meaning of the code itself, when tackling drivability problems. We need to look at all available data instead of just focusing on one specific area.
Vehicles sitting on car lots can experience a lot of problems because they sit for long periods of time. Batteries aren't unhooked, and can drain. On this Dodge Caravan, the driver door lock was malfunctioning.
