I have a Mazda CX 9 bought on december 2015, and now the shift lever gets locked when parked. Do you have any other Mazda CX 9 car with the same problem?
That really wouldn’t help you if we did, now would it?
Could you explain your problem a little more fully. As I read it now, when you park, your shift lever is locked. If this is an automatic transmission, that is normal.
Neighbor has one that does the same thing,
Her problem was she was trying to move the shift lever before stepping on brake pedal.
Make sure you are pressing the brake pedal BEFORE you even touch the shift lever.
