“While driving our 2003 Land Rover Discovery Ii hse today, the throttle suddenly and unexpectedly stuck in the full position. My wife was able to avoid traffic, control the vehicle and get the transmission in neutral. The vehicle was towed to a Land Rover dealer, and they determined that the throttle butterfly valve had stuck. I researched this and came up with NHTSA case number 03v133000 which deal with this exact issue for this model year vehicle. The dealer claims there are no outstanding recalls for my vehicle and refused to replace the part under this issue. …”
