    Problem: Gas Cap Door Won't Unlock

    So last night I get to the gas station, push the gas cap door and it wouldn't unlock. Tried 1000 times and it wouldn't budge. People looking at me like I'm crazy. Drove it home,....and tried another 1000 times with no luck. I had half of a quarter tank left & live 35+ miles from nearest dealer so I'm a bit concerned. Googled/Youtube'd, found some videos (none were CLA models though) that spoke to a latch in side panel within trunk. No dice,...I couldn't locate the latch. I gave up and went to bed...............then this morning I went outside and the door was wide open (car was still locked).

    Really SMH at MB right now.

    The gas cap door won't open if the car doors are locked.

    Believe you me, I searched for debris or anything disrupting the connection as I believe it's an actuator at play. Not spring loaded as I previously thought. But saw nothing whatsoever. Rules out blown fuse too I think.

    Now it locks/unlocks fine but I went ahead and made an appointment for Saturday. My experience (eg - Comand, distorted audio w/SD, gas cap door) so far with MB is less than ideal, while not major it's embarrassing.

    Same thing happened to me at the gas station. I just drove directly to the dealer, who couldn't get it opened either. They took it back to the service shop and somehow pryed it open. They filled it up with gas, ordered a replacement mechanism, and said come back in two days. The part came in and they swapped out the parts that open and latch the door. It's not you, let the dealer fix it.

    UPDATE: So I ended up taking my car into the dealership last Friday (9/25) and the service tech could not duplicate the problem. They had the car for about 2.5 hrs, told me that if it happens again bring it back. This morning headed to work, I stopped to gas up and yes it happened again. Pulled away from the pump and off to the side,....tried numerous times no luck. Then just as I put the car in reverse, the door popped open. So I'll reschedule another appointment.

    Sorry, just checking - you didn't lock your car at the gas station, did you?

    @jc3513 , sounds like you're not the only one who has experienced the problem. I'd tell your dealer you want a new mechanism. It's a good thing you had enough gas to get home. It's not the kind of thing you want to happen when you're stranded far from home or in desperate need of gas. Good luck getting it fixed.

    Just closing the loop on this, yesterday they replaced the defective part. I'll keep an eye on it.
