I have a 2010 H3 Alpha that (except for this) runs well. Whenever I get out with the key in the ignition (running or not) and close the driver's side door, that door locks. The other 3 doors remain unlocked. This is especially annoying when valet parking, running back into the house for a second, and overall daily life.

I brought it to a dealer who ran their software checks and said there was nothing they could do. I then went to a mechanic who also couldn't come up with an answer beyond "it's something you'll have to live with."

Anybody else have this problem, or know of a fix? Thanks.

 

you tried the stuff in the instruction book about lock/ unlock choices huh?

 

This is for sure a malfunction and is not covered in the Owner's Manual.

 

Yo Pete.... whazzzzz up?


Question: Do you still have the crappy OEM battery terminal connectors? If you do, search out some of the many threads on why to hack them off ASAP and get a quality aftermarket set.

You likely have had a voltage variation that has caused some kind of BCM or PCM brain fart. I would start by disconnecting the Positive battery terminal for 3-4 minutes, and then hook it back up ans see what you have. Of course if you were going to change out to aftermarket battery terminals, just do it then.

 

Hey Doc, RK and Happy:

Thanks for the quick replies. Owner's manual useless for this. Doc, as far as I know it still has the original battery terminal connectors -- I'll try your suggestions. Thank you, you're the only one who's offered hope outside of this forum.

I understand the problem. a simple first thing,zero cost and effort is try the instruction.
then unhook batt,clean and tighten the conn.


those stock conn are fine if used properly.
trouble starts when heavy handed guys bend them!

 

I noticed a similar issue but it is intermittent. I usually notice it when I get out to fill up at the gas station and realize the driver side door is locked with the keys in the ignition. So far I have been lucky and the rear driver side door is unlocked. I also try to remember to roll down the driver side window or leave the door open just in case. I haven't taken it to the dealer to see if they have heard of the issue before.

 

I tried the disconnect the positive terminal per Doc's advice --- so far so good. Not sure why, but it seems to have done the trick. THANKS

 

The battery terminal disconnection was short lived. I am now officially locked out again. Anybody? Buhler?

 

If you ever get to the bottom of this, PLEASE share.
