Mercedes no longer supports the sos ( tel-aid) system, so this system no longer works...each time you start the car, the sos inoperative warning light is on, and it blocks other safety features ( speedometer etc..). You have to reset the light each time you get in the car. Without the support of the system there is no emergency alert theft tracking ,airbag deployment sent to MB etc etc. Mercedes no longer services this feature, and this is one of the reasons we bought this car. It's a tremendous safety concern. Even though there are dealer bulletins about this, there is no fix. All these cars should be purchased back by MB. I'm uncomfortable driving a car that could be involved in a collision, and the car not notifying MB, or the police

A driver in my household was driving at normal speeds and smelled smoke in the cabin. She pulled over immediately to the nearest gas station. In that short time, there were FLAMES coming from the center console area. She ran inside to get employees with fire extinguisher. The fire was put out and police/fire department were called. The car was un-drivable, and my insurance declared it as a total loss (it would cost more to repair than the current blue book value). I had a similar problem previously with a Mercedes 2014 CLA250. That was a smaller fire, but melted the console area. I will be submitting a report for that one as well, even though it happened several years ago. After that incident we went back and forth with MB corporate and ultimately took it to dealer and ended up trading in for this one. Both fires were electrical fires from wires underneath the center console.

We have had this car about a year, we encounter numerous occasion the the "collision assist plus" has engaged intermittently w/o any reasonable obstacle in front of the car when it is in motion. About a month ago, the car gave message "collision assist inoperative" and I can even get the car in gear not with multiple restart. Last week I went out with my wife and the car stop on the busy street on the stop and go traffic and the car did "auto start stop" was unable to restart and it disengage the transmission and I had to restart the car manually and reengage the transmission. I had file complaint about intermittent "collision assist " condition to the dealer (house of import, buana park, ca), the service adviser said it is normal for the collision assist acting up some time. I believe there are some software gremlin or some other ecu issue need to be address. It s a safety concern to keep driving this can w/o any solution, I did contacted mbz USA, they offer no help nor solution at all.

I was driving my 2015 mb gla250 4matic [xxx] and suddenly 5 warning alerts popped on the display and the respective signals turned on the dashboard. The 5 warnings were: 4matic currently unavailable, inoperative ABS, parking break, collision prevention assist plus inoperative and check engine. In addition, the steering wheel became heavy at the same time. I turned off the car and turned it on again and at that time only the check engine signal was on. As soon as I accelerated the car and the car changed to 2nd, all the original lights and warning turned on and the steering wheel became heavy. I am sharing this information because I've read multiple similar complaints online. The warranty of the car expired in december 2018 (3 months ago) and back in november my vehicle stayed a couple weeks in garage isla verde (puerto rico) due to problems with transmission. My car has 18,000 miles and I find these types of errors unbealivable since it's an almost new unit. Information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).
