I just picked up a 2015 CPO S550 and am having problems with the door locks. Despite the car being locked and the door pins in the lowered position, the doors can be opened from the outside which then sounds the alarm. This happens without the smart key being anywhere near the doors. When you grab the door handle the pin doesn�t raise to unlock as with Keyless Go, but the door still opens. Does anybody have any thoughts?

My thoughts are probably obvious. Since it�s CPO take it to dealer and get it fixed?

Thanks for the reply. The dealer is less than stellar, but I wanted one with the MBC, really just for the ABC, and they had one. No. they did not do a proper CPO inspection despite signing the certification. Mild curb rash on the wheels, a tiny dimple on the trunk lid, an inoperable ash tray (just for the 12v plug), a broken handle on the small compartment under the driver�s seat, and a missing comfort box were all �somehow� missed but have been or are n the process of being rectified.

You our can imagine while I�m hesitant to ask them how something should work I forgot about all the stuff that was wrong and now I�m mad! Thanks though.

I do and a favored one, but I thought I had to get all of this wrapped up with the selling dealer. If that�s not correct then I�m elated. Again thanks for the reply.

All of the missing and obvious damages should be addressed to your purchased dealer and ask them to provide their CPO inspection report. Be sure to also check the tires ( look at the inner tires and not just the outer tires ) to be sure the tires are up the CPO standards.

The door issues can and will be address at any Mercedes dealer since it�s still under CPO warranty and ask the second dealer do a complete and through inspection of your car.

Yes, you can take your Mercedes to any dealer in the country for warranty work. In regard to the door opening when it shouldn’t, it could be a software issue for the Keyless GO that needs to be updated, or it could be a problem with the sensor on the door handle. Have you tried opening the other doors when they are locked? Do all of them open? Or just the driver’s door? Maybe the latch on the door needs to be adjusted.

Check out this thread. I had a similar issue with my rear passenger drivers side door. They replaced the locking mechanism.

Thanks to all who replied as you provided much needed and appreciated comments or suggestions. The ability to open the door while locked I know happens with the driver�s side rear passenger door, and the front passenger door. I contacted Mercedes Corporate for assistance in working with that dealer, and they too were perplexed with the doors. They were also concerned about the number of items missed during the supposed CPO inspection. The dealer was upset that I engaged them, but I explained not replying to my emails sent days before, a work voicemail box that was full, and their general lack of concern provided me no comfort that my issues would be addressed. Regarding how these things were missed during the CPO inspection that took place on 12/20/18, their response was the car had just come in and with the holidays. I purchased the car about 25 days after the certification and my point was they should never have offered it for sale as a CPO until after everything had really been checked out. Oh well. Live and learn and once done, I�m done with them and will move on.
