Filed May 9, 2020 · Electrical · CA

After a long period of rain, water pooled on rear driver and passenger floor. Windows would not function, door locks would not function, turn signals didn't work. Instrument panel flashed warnings of engine problems, brake failure, airbag problems. Often lost entire panel while vehicle was being driven on highway, measurements going dead. This has been going on for months and is getting worse.

Whilst driving, the instruments on the instrument cluster dropped to zero and the warning lights started flashing. After shutting down the car, and then restarting, the fault cleared. Ever since, the electric windows and door locks have worked only intermittently. Volvo diagnosed the problem to the a-pillar connectors, which they said were old, and newer ones had been made. Volvo will not pay for the replacement since the car's warranty has expired. After doing some research, I found out that volvo had issued a service bulletin addressing the a-pillar connectors, and I also found quite a few volvo owners that experienced the same problem.volvo knows they have defective a-pillar connectors in some of their cars, why has a recall not been issued?

1. Severe summer thunderstorms and rain. 2. Drove approximately 1 mile and right blinker stayed solid green after turning. Drove about a mile further onto highway entrance ramp and car indicator lights flashed ABS brake failure and air bag failure, then all car instruments (gas gauge, speedometer, tachometer, etc) failed for about five minutes. Instruments came back on but ABS brake and air bag failure continued to flash for about 1 more minute. Drove directly to dealership. 3. Service department took the car right in and applied grease to the harness connector which should alleviate problems as they are known to get wet and corrode. Please note this is a 2006 model as I have read on the website that the 2004 model has the exact same problem. Additionally, driver side door locks and power windows intermittently inoperable leading up to this failure. Had a scheduled appointment to remedy this situation but brought the car in early as the car was inoperable without instruments.
