2001 Volvo V70 electrical system problems

Tl* the contact owns a 2001 volvo v70. The contact stated that while driving 60 MPH, the front driver and passenger seats were melting and black smoke was emerging from the seats. Additionally, there was an abnormal burning smell emerging from the vehicle. The contact stated that the battery was replaced in the vehicle prior to the failure. The contact disconnected the circuits to the seats. There were no warning lights illuminated. There were no injuries sustained.

Repeated skipping and hesitation of our v70 t5 sw along with a "reduced performance error" message resulted in our going to the danbury ct dealership, where they told us the throttle and software needed replacement. The cost was $899.17. We service our car regularly and have the documentation to prove it. We have had no accidents with the car prior to this engine problem.
