Safety concern: 2007 Volvo S40 electronic throttle module failure - causing "reduced engine performance" message and vehicle (2007 Volvo S40) suddenly slows down while in motion, limps and cannot go higher speed. Had barely exited the freeway on 1/24/2017 and this happened as I was on ramp. Could be extremely dangerous if it happened 1 minute before when on freeway. Turned vehicle in right away to local Volvo dealership (which was luckily within 15 minutes) and they diagnosed it to be faulty electronic throttle module needing replacement. Mileage on car 129,000 miles. Wanted to report so this issue can be looked into for safety concern and if the huge cost of replacement can be offset so owners can have peace of mind replacing it timely if there is a recommendation or bulletin (similar to timing belts etc. - which I don't believe there is currently for electronic throttle module).
