What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
The fuel injection wiring harness has insulation that is badly cracked and flaking off causing fault codes and poor running. The body harness has cracked insulation as well. While this is an older car it is low miles and has spent its life stored indoors. I have a 1968 model amc car. The wiring is fine still.
What to check before buying
- Electrical system. Scan all modules, test the battery and alternator, inspect connectors near the impact zone.
