2017 Volvo XC60 Electrical system Problems

“Constant problems/failures with start/stop function. Car's electrical system will completely shut down for no reason while in traffic and engine will not restart. Car has to be shut off and system has to be re-booted. Dealer service dept can find no problem. Most recently, car's starter motor failed and had to be replaced under warranty by the dealer. Having the car's engine start/stop system constant fail is a serious safety risk. We had serveral near-miss accidents caused by this failure. …”

Even after we got out of the car, we watched other cars nearly hit it because it couldn't be pulled over and the emergency flashers wouldn't turn on. …”

Followed VIDa fault tracing and found the loose tension in SRS pins in the driver door harness. They had to replace the SRS terminal pins and splice wiring. The dealership did mention that this has happened with 3 or 4 different Volvo models already this year. …”
