2014 Mercedes-Benz CLA250: ABS light or ABS activating

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 30 MPH I received a red parking brake error and my car began to be very difficult to steer. I then pulled over and received a yellow pre-safe mode error which illuminated the check engine light, ABS light, parking light. I took it took the dealer and was told it was a right tire sensor. This appears to be an ongoing problem with these cars and it's definitely not safe. This definitely needs to be recalled.

As I was driving on the highway around 65 miles per hour, the vehicle's check engine came up and said " inoperative, pre safe inactive" I freaked out. I was at highways speeds and it was inoperative. I noticed that the power steering was affected and the vehicle was unresponsive when I accelerated. The ABS system was disabled, I was scared even to brake because I know that when the ABS system is disabled the brakes can lock up and cause an accident, injuries and even death. I have noticed that many cla250 owners have the same problem.

While driving under normal conditions the car stalled with no warning. A number of dashboard warning lights came on including the parking brake, traction control, ABS, engine, tires, airbag, etc... There was a red message in the information display that read "service required. Do not shift gears. Visit dealer.", that alternated with a yellow message that read "traction control inoperative. See operator's manual." I was able to coast close to the curb to move out of the traffic lane but the car would not turn over. A flat bed was called to take it to the mercedes dealership.

I just picked up my car from mercedes service today, 7/10/2014 for the issue described below. It had been in service since 7/1/2014. The service representative said that it was an electrical issue. One part they needed was back-ordered and unavailable from mercedes so the mechanic rebuilt the connection. That still did not stop the fault code so in consultation with mercedes the service department replaced additional electrical components and believed they resolved the issue. The exact same incident occurred today, approximately 30 minutes after picking the car up. While driving under normal conditions the car stalled with no warning. A number of dashboard warning lights came on including the parking brake, traction control, ABS, engine, tires, airbag, etc... There was a red message in the information display that read "service required. Do not shift gears. Visit dealer.", that alternated with a yellow message that read "traction control inoperative. See operator's manual." I was able to coast close to the curb to move out of the traffic lane but the car would not turn over. A flat bed was called to take it to the mercedes dealership.

On sunday, october 27, and tuesday, october 29, 2013, my vehicle listed above had warning lights come on that stated, "pre safe, functions limited, inoperative." in addition to the words, the esp and ABS lights illuminated. I took the vehicle to penske mbz in west covina, ca, on wednesday, october 30. They repaired the vehicle by doing a software update. On saturday, november 2, 2013, the codes returned and I took the vehicle back to where I bought it, encino, ca, mbz. I was told they could not replicate the codes and they found no problem. This is unacceptable! The vehicle is still at encino mbz as they are trying to replicate the problem. When this malfunction occurs, the vehicle loses power and has very limited acceleration. It has occurred twice on city streets and twice on the freeway, both in eco and sport mode. On the city streets I am able to just pull to the curb. On the freeway, it becomes a possible life threatening emergency. There is only very gradual acceleration, and at 65mph, limited acceleration is very dangerous. These four occurrences have taken place in less than a 10 day period and no long term repair has yet been accomplished!
