What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
Consumer was parked in driveway, turned on the engine, shifted from park to drive, and all of a sudden vehicle accelerated and took off. Damages caused to property wall and another house. Dealer/manufacturer were contacted.
Jaguar coprate has acknowleged problem with dealer..no help in sight..the corprate office says vehicle must be fixed by dealer or will not warranty for seat belt.
When shifting from "park" to "drive" vehicle bolted ahead at full acceleration without my touching accelerator pedal. Applied full brake pedal with no effect and could only stop vehicle by turning off ignition with key. Jaguar dealer advised me that "build up of carbon around throttle linkage" caused the problem.
Driver's door locking switch on door latch went bad & broke. Would go up/down while driving. Also, while driving seat belt came undone & consumer went against the steering wheel. This had caused an interference in driving for the driver. Would have to shut vehicle off just to get the seat belts to retract.
When seat belt retracts it goes across the steering wheel, causing wheel to steer, making steering difficult. Dealer contacted ,and cannot remedy the problem. Problem still exists. Provide further information.
