I want to let others know about the problem we have had with our 2014 Volvo XC70, which was still under warranty. A trailer malfunction light kept coming up and the sunroof leaked. We took these problems back to Volvo to have them repaired, but they were unable to. The car, while travelling at 80 km/h had a massive electrical fault and the first message to come up was Trailer Malfunction, even though we have never towed anything with the car, then brake system failure, and finally total system failure. This resulted in losing control of the car because everything is electric. The air bags exploded and then the cabin filled with smoke and fire quickly took over the car. Luckily I was able to put the car into Park and drag my kids out and run down the road. When we turned back the flames had engulfed the car. Volvo has now closed the case with no investigation. Has anyone else had this problem?
We haven't heard of any other reports of this, but it sounds serious. I would ask Volvo for an explanation of what happened and why. Seems an investigation is warranted.
