Default Won't start from PARK, but will from Neutral....anyone else?

My car is just about 3 years old, and it lately has decided to only start from park 25% the time, and the rest I shift to N to get it to turn over. I think the sensor that tells the ignition whether the car is in P/N (the only starting positions) might be bad in the P position.

Anyone else have this problem? I'm going to take it in on the weekend and hopefully its under warranty...even if it is a free fix its still annoying!

Nothing. I can turn the key, but it won't start...just like if you were in R or D.

The neutral safety switch needs to be replaced. I had the same problem (2006 Mz3 Automatic) that it wont start on Park, I have to move the gear shift to Neutral and it will start. I replaced mine by myself, not a warranty part. The part will cost $65.

Got that right. The neutral safety switch needs to be replaced. The safety switch’s main role is to keep track of the position of the gear selector lever. It prevents the engine from starting if the gear or transmission is not on neutral or park position. If the gear is on this position, it would be easy and safe to start the vehicle. Yet there are some signs that will pinpoint defect on this part. One is when the lever has to be shifted from park or neutral mode in order to get the engine to start. Another, which you are encountering, is if the car starts in Neutral but not in Park mode. That’s the go-signal for a replacement. Hope it helps.

If you replaced it yourself, can you tell me how? Any pictures? Maybe somewhere on the web that has instructions. I really don't want to go to the dealer and have them charge me $200 or more. Thanks.

Mine happened when the Cold Air Intake lower mounting bracket got in the way of the cable attached to the switch. The cable kept snagging and wouldn't return to Park. I relocated the mounting brackit toa readily available bolt opening near the area.

The ATX uses the transmission range switch as the neutral safety switch. It is on top of the tranny near the gearshift mechanism.
