Been working on this problem. My 10 mph auto locks work about 50% of the time, with engine off get in to go to work hit 10 mph auto lock locks the doors (most of the time). Get to work engine off lock the door with the fob day is over unlock with the fob start the engine and go- this is the hit or miss part it may lock may not. When it does not work I don't hear any locks cycle not even the gas cap. If I hit the toggle inside it works 100% of the time. I was able to search and did find thread but it had to do with opening the door with the engine running ( like dropping someone off) and then the auto lock would not reset- my problem has been with the locks after starting the engine. Is it broke or what am I missing? The dealer is 2hours away and with it working part time just hate to show up with out coving all my bases. Matt

 

You are not alone Matt. Have exact same symptom. Auto lock works most of the time. Only thing I have noticed is when it does not work am in a situation where there is not a clear pick-up in speed through 10 mph. Like on a long drive way or in a big parking lot.

Never bothered to mention it to the dealer.

Good Luck,

Alan
