Two problems related to automatic transmission park/neutral start switch have been reported for the 1999 Plymouth Voyager. The most recently reported issues are listed below.
Consumer's 3 year old son was able to disengage park gear which allowed vehicle to roll back through his neighbor's garage door without the use of a key.
Failure of this part caused the vehicle to violently shift to 1st gear at 45 mph. The speedometer and odometer did not read. Vehicle had to be towed. Dealer stated that this part should not have failed on such a new vehicle. I purcahsed an extended warranty, which covers powertrain, electrical and standard instrument cluster, but was told that this sensor was not covered, eventhough it controls the instrument cluster. I paid $130 for repair. If this had happened in traffic or at highway speed I shudder to think how the vehicle would have reacted, since the sudden, unexpected downshift caused the vehicle to lurch forward violently. The dealer's service rep said that this part did not usually fail, but that in the past month they had replaced more than usual. I have only had this vehicle for 7 months and it has already left me stranded. Overall, my dealer and service rep were very polite and friendly. Please let me know your expert opinion about this incident.
