Several times ( 5or 6)I have returned to my GLA to find the tailgate open, despite the car being securely locked. I have been so concerned about this, that I carefully check that the tailgate is closed from a distance when I leave the car, so I am sure this is not me accidentally touching the key fob and opening the tailgate.On two occasions, the car has been on my drive locked and with my car keys put safely away. On these occasions I have walked past the car (taking the dog for a walk) and the tailgate has been shut and on my return 30 minutes later the tailgate has been open.Has anyone else experienced this problem or got any suggestions?David

Welcome to the forum David

That sounds very worrying - what has your MB dealer said or done about it so far?

Is your spare key secure i.e. are you 100% sure it's not your kids or friends playing a prank?

Does this always happen in the same place e.g. your home?

RoyThanks for your interest.Booked in at local MB dealers for Thursday but checking to see if anybody else had experienced the same problem. They are also having a second go at sorting out the intelligent light system - both headlamps replaced a few weeks agoand still not operating correctly.It has happened at to many locations for anybody to be messing about. The only possible thought that I currently have, is that my son has a Ford Focus andon both occasions it happened at home, he arrived home shortly beforeI found the tailgate open. On one of the other occasions (20 miles away), when I came back to the tailgate open, a Focus was parked next to it????D

Hmmm. Worth telling MB about this. It's very unlikely, but I guess it could be some sort of clash of code between the Focus remote locking system and your Merc's remote tailgate release.

Hi David, My wife had the same problem a few weeks ago with her GLA 220 CDI 4Matic when she was at work and someone told her her boot door was wide open, I thought she must have inadvertently pressed her key but she was definite it was locked when she parked. I will be interested to find out what MB discover on yours. My wife has had a few issues with her GLA, collision avoidance, fuel cap wouldn't open, EGR valve replaced, recall for seal replacement, etc. Between us this is our ninth merc and the first with so many issues.

Hi SparkyThanks for this. I know for certain that the key was not pressed on the occasions I mentioned. In fact it is most unlikely that this can be done accidentally because unlike the central locking, that unlocks immediately the button is pressed, the tailgate button requires to be pressed for a full second before it activates the tailgate.Like you, I have had many new Mercedes E classes and my sense is that the quality assurance on the GLA certainly seems to have slipped - Intelligent light system required two new headlights, rattles and from day one. Let's see what the dealer finds on Thursday.

There seems to be two versions of the GLA out there at the moment: one with lots of problems, and the other with none. Is it just that those few people with issues are posting more, or am I the only one with a fault-free car (so far)? I too have had lots of Mercs in the past, but this one is definitely my favorite!

When I had the 'loan' car (one of 5, I might add) I had MB Assist out 3 times due to the boot catch not engaging. So the boot would go down, settle, disengage and ping back up. When I returned the car, I mentioned this to them and they still proceeded to put the car out for sale on the forecourt and I knew full well the it hadn't even been looked at. I have videos of the boot not engaging and they just laughed it off.
Not people I ever want to encounter again in my lifetime. Sorry for the bitterness, I wish I could be more positive about my experience.
And the ILS on my actual car.... Well, they laughed off that there was any issue with that either. Mine displayed 'system inoperative'. They denied the fault was there.

The simple answer from the local MB Dealership was "that their diagnostic tool did not show a fault, so they cannot do anything". I then asked what would happen if anything was stolen from the boot under these circumstances and I was told "you can always claim on your insurance".I pointed out that there were a couple of other examples of this problem on the forum and was told "MB don't take any notice of forums, they only take notice of diagnostics".I just wonder where to go from here, knowing full well that on occasions the boot opens intermittently and yet having to leave the car in car parks, etc?D
