I want to add my documentation about the failure of the throttle module and subsequent lack of appropriate action. The unit in the 2000 Volvo S80 failed to bring the car to a complete halt in traffic in December 2004. Subsequent repairs to solve the problem were $845. If Volvo sent out a notice for etm repair refunds last winter, I did not receive it despite living at the same address as when I purchased the vehicle in Dec 1999. I also want to call your attention to the increasing problem with the dstc system as evidence by activity in the chat rooms. Our vehicle shows a persistent dstc service message that the dealer claims can not be adequately diagnosed without first replacing the yaw sensor for $668. Others with this problem have turned to buying and self installing rebuilt abs units which the NHTSA should be proactively seeking to understand. The cause of the abs unit failure? some claim it is the vibration and pounding from the entirely inadequate front end suspension and wheel system causing the electronic parts to fail. I can attest to the suspension problem having spent $1790 yesterday to replace front bushings, stabilizer links, struts and spring seats on a car with 64k miles. The front struts previously were replace in Jan '04 at a cost of $726 when mileage was 40k. I've also had to replace the ball joints several times already.
