2014 Mercedes-Benz CLA250 transmission problems

Filed Oct 9, 2023 · Transmission · GA

Please let me preface this by saying that I am a certified aircraft mechanic and have a good working knowledge of cars. My vehicle had NO prior indications, symptoms or abnormalities! This was completely out of the blue. Absolutely no warning that this was going to happen. The transmission of my 2014 CLA 250 Base model, while operating at 65mph on the interstate, all on its own, went into neutral and now will not engage into Drive. Initially following this incident, as I dogged the other vehicles on the interstate and coasted to the emergency lane, there were the following warning lights: ABS, TRACTION CONTROL, PARKING BRAKE accompanied with the alerts….PRE-SAFE Functions Limited, ABS/TRACTION CONTROL Currently Unavailable See O.M., Parking Brake See O.M. I then took it to the MB dealership and after they attempted transmission adaptation (which was not successful) they showed me the following fault codes: 079200-RPM sensor 1 has a malfunction, 287C00-Adaptation was not completed successfully. The alerts now state….Service Required: Do Not Shift Gears, visit dealer. The dealer wanted to change the transmission. I refused. I have had zero noticeable issues with the transmission with 72,000 miles. I had the transmission fluid replaced at 65,000 miles. I baby the car. I shouldn’t need to explain the dangers of a vehicle, while driving, randomly shifting into neutral, and not being able to be shifted back into Drive. I attempted all possible means of shifting the automatic transmission into drive, including the use of manual gear selection, and none of them worked, even after shutting the vehicle off and restarting multiple times. This is an extremely DANGEROUS malfunction!!

While driving the transmission slips into neutral. Must come to a complete stop and turn off the car then turn it on again to shift into gear.

While sitting at a red light, the vehicle will put itself into neutral. It's happened multiple times and we've brought the car at the dealership each time it's happened yet it still hasn't been fixed. This is a serious safety concern and mercedes needs to look into a fix asap before they have a lawsuit on their hands. In addition, the entire engine has already had to be replaced! So far, to address the issue about the vehicle putting itself into neutral the dealership did a transmission control update and replaced the valve body. It's now back for a third time at the dealership and we've told them that we aren't picking it back up until they can guarantee tee the issue has been fixed. When the vehicle puts itself in nuetral the 'pre-safe function limited' appears on the dash. Also, it's hard to recreate the issue as it only appears randomly.

On this day, I was nearly killed in my 2014 mercedes cla250 4matic that stalled on a highway in new york city. The car has roughly 40,300 miles on the odometer. I was driving on the brooklyn queens expressway at 4:00am. The car's motor stalled and the car came to a stop in the left lane. There were no shoulders. I attempted to get the car restarted but all I got were flashing dashboard lights. I attempted to put up a warning triangle to the rear of the car, but the traffic was moving too quickly for me to safely do that. I sat in my car and buckled my seat belt. I called 911 to announce my emergency and I contacted my car's insurer for a tow truck (they provide such a service). Within moments, a toyota with tlc plates smashed into my car sending me into the barrier. The rear of the car was broken and deformed. The front of the car is okay, but the appearance of the rear is such that I believe I lost my car. I read online that this model has a stalling problem and that others have gone through this. I was one of the unlucky owners and I will be suing. This car's airbags did not deploy and I am injured and being treated in a hospital.

There is a design defect in the rear differential. Multiple independent repair shops have reported this. Mercedes benz has an internal "service technical bulletins" to their dealers on this.issues. There are numerous reports on this on different forums on mercedes cars.

Over a year I am complaining that I am getting unusual noise from my car. Mercedes benz silver spring told me that because it has low profile tire and rims get bend from inside causing the noise. I took their word but issue remain there. I just took the car for other issue and told the service manager look into the issue and they came back with issue 'split differential issue' in the car which will cost around $4100.00. I did internet search and find out that there are other people who cla 250 in 2014 got the exact issue. I own cars for so many years but never heard anybody have similar issue. Mercedes is not doing anything about it. Please help. Thank you.

I was getting off work and I was about to get out of the garage and I drove for about 100 yards and I get the check engine light on, power terain light on saying disabled and on the dashboard it said inoperative see operators manual and also pre_safe functions limited. It was going back and forth between these two. When I was driving going about 5mph, the car would speed up by itself without me touching the gas pedal, then it would slow down and speed up again. It was like I was learning to driving stick shift, stop and go, except the car was doing it by itself. Then I parked the car, and the arrow in tachometer was going up and down. It would go to 1.5 and then drop to .5 every second or so. Then I stepped on the gas and floored it while I had it on park and it did nothing. I shut it off and started it again to see maybe it would get fixed but it didn't. I left the car there overnight and the next morning when the tow truck came I started it, and only the check engine light remained on, everything else was gone. I drove it for about 500 yard to get it out of the garage to make it easier to tow. I have heard many other people had some issues with 2014 cla 250
