During night rainstorm, front and rear wipers, turn signals and high beams all failed. This was the result of a design defect that allows water from panoramic moonroof to drain into the floor where it compromises electrical connections and modules. In addition to potentially catastrophic safety component (wipers, high beams and turn signals) failures, the water damage compromised the seat belts, as well, which also required repairs. Insurance adjuster confided that this is a frequent, common problem. Repairs took 10 days and cost $8700! Both the insurance adjuster and the dealer stated that there is no maintenance procedure an owner can do to avoid this problem.
The contact owns a 2020 Volvo XC40. The contact stated that while his wife was driving at an undisclosed speed, the speedometer and the infotainment system screen turned blank. The vehicle then lost motive power. The electronic stability program (ESP) warning light was illuminated. The contact's wife veered to the side of the road, and the contact arrived at the scene. The vehicle was able to be restarted. The vehicle was taken to the dealer, where it was diagnosed that the failure was related to the software control module and SRS air bags malfunction, which caused the vehicle to believe it was involved in a crash and to shut off automatically. The dealer determined there were no signs of a crash and performed a software update; however, the failure recurred while his wife was driving. The message "12V Battery Low Charge" was displayed. The contact's wife pulled into a parking lot and was able to restart the vehicle. The dealer was made aware of the failure. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was 30,453.
The electrical system on my car apparently failed, which rendered the car unable to start and drive. Park Place Volvo claims that there is water, that penetrated the seals, from underneath the car. Although there were no visible signs of water, Volvo claims that the rain caused this issue. Volvo has refused to honor a warranty for the alleged defective seals, and sent my car to its collision center.
