The issue has to do with continuity at wiring connections that could result in premature failure causing a great deal of time to be spent troubleshooting to find the broken connection.

It should be noted that this more of a performance and reliability problem then a safety problem.


These kinds of problems can be a bear to diagnose. Although I suspect it might get a little easier if they are aware that there might be wiring harness issues.

Are they going to install the chains at the same time they have the cars in to fix the wiring?
