2014 MERCEDES-BENZ CLA250 Complaints

The contact owns a 2014 Mercedes-Benz CLA250. The contact stated while driving at approximately 70 MPH, the vehicle stalled. The contact stated that when the vehicle stalled, an audible chime sounded, and the air bag warning light illuminated, and a RED triangle symbol flashed on the instrument panel. The contact stated that the instrument cluster went blank, and the vehicle lost power steering assist. Additionally, the brake pedal was very difficult to depress. The contact was able to restart the vehicle after several attempts, and the vehicle returned to normal functionality. The contact stated that the failure reoccurred. The contact drove the vehicle to a dealer who diagnosed the vehicle and determined that the battery needed to be replaced. The vehicle was repaired. The contact stated that the failure reoccurred and the vehicle had not taken back to the dealer. The manufacturer was not informed of the failure. The failure mileage was 76,850.

Apparently the TPS (Throttle Position Sensor) which is built into the gas pedal on this 2014 MB CLA250 only lasts so long before it becomes defective under highway conditions and causes the vehicle to go into LIMP MODE. When full acceleration is necessary, the unit will work for perhaps a few months or less, and then continue to fail worse and more frequently with each attempt at full acceleration. At highway speeds, this is an essential feature in a 4-cylinder vehicle such as this one and without the necessary acceleration capability, can expose the driver to serious risk of collision with other on-coming vehicles traveling at highway speeds. This "Limp Mode" features is extremely dangerous and hazardous to not only the driver of their vehicle, but to other drivers around them since they are left in a devastating position of being unable to accelerate normally and as necessary and as one would expect in any vehicle, let alone a Mercedes Benz. Never before have I driven a car that falls out of full acceleration mode only to subject the driver to serious collision circumstances. Whoever the imbecile is at MB engineering who incorporated this Limp Mode Feature should be fired!!! To make matters worse, this cheaply built TPS, which is the cause of the problem in my vehicle specifically, was only warrantied twice by the dealer and now they will not replace it under warranty which is a two-year period. I've only had the part 5 months before it failed again due to poor manufacturing and I had to pay all over again for a new one despite my warranty validity. There have been many other MB owners who have the same complaint for Limp Mode, which tells me that it's definitely not me, but rather the poorly built or engineered vehicle, as a matter of fact. MB has denied having these complaints to me, which of course, is a lie. That's misleading and deceptive business practices in my State and MB needs to live up to its warranty provisions and respect its customers.

I was driving my 2014 Mercedes CLA 250 on [XXX] traveling away from Fairfax County and towards Prince William County on Christmas morning right before [XXX]. The front right passenger side wheel started shaking and then flew off. I brought the car to a stop on the left hand shoulder of the road on three wheels. My wheel hit the metal fence and then ricocheted back across to the left crossing both sides of traffic (four lanes), hitting a concrete wall and becoming airborne before landing in the stream below. It was sunny and there was no rain. Speed was 45 mph. Witnesses observed the incident and I have their contact information. A police report was filed. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

As I was driving yesterday afternoon, I heard a noise and normally we don't hear any type of noise or air coming into the car. I decided to open the sunroof to see if there was something wrong with it like if it was stuck open or if something was stuck in it, and the whole sunroof almost flew off the car. I had to pull over as fast as I could into the break down lane and it took me a while to close it and it still seems to be open, I didn't see anything stuck in the guide rails or in the area when closing it. I was very scared for the safety of my children and myself and for the other drivers on the highway. I have made an appointment so the shop and check the car out and run some diagnostics. There are no warning lights or messages prior to the sunroof almost flying off the car.

Component failure was steering column module. Safety issue was air bag could inadvertently deploy while driving. Recall NHTSA # 17V627 was issued. Vehicle inspected by Stargate Garage, Caliber Collision and Mercedes of Pompano Beach FL. Message displayed was front left malfunction and red warning light for SRS system. Warning message and red light appeared 18 months after dealer supposedly repaired this recalled item. Vehicle was returned to dealer to make proper repair on this recalled item and they refused to replace it. Steering column module was replace by Stargate Garage and the message left front malfunction and red light warning SRS no longer appears on instrument panel. Stargate Garage was paid $685 to make this repair which should have been the dealer's responsibility. Therefor I am requesting that the dealer reimburse me my out of pocket expense of $685.00 since it was there responsibility to make this repair under the recall that was issued. I was unable to upload my documentation so I will also be sending this information in the mail.

My engine light is and as per mechanics I have seen it is a very common problem with mercedes benz around crankcase ventilation actuator. As per mechanics its faulty part and mercedes have changed it for new models but there is no recall on the older models. Cost to repair the part is around $3500. Issue with the part if causing environment problem as mileages is reduced and more fuel burning. This eventually impacts the engine and car.

The contact owns a 2014 Mercedes-Benz CLA250. The contact stated that the front panel around the panoramic roof was separating. The contact called a dealer and was informed that there was a recall for the panel separation, however, the VIN was not included. The contact was informed that the VIN was not included in NHTSA Campaign Number: 21V197000 (Structure). The vehicle had not been repaired. The manufacturer had been informed of the failure. The failure mileage was approximately 150,000.

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!!

As I was driving, the car is on D but it slips into N and I cannot shift to any other gear accept P. This happens randomly and happened three times. I noticed the GLA250 also had this issue. I have to turn off my engine and restart my car to get it running again normally.

When accelerating, the car loses power. My teenager was almost hit by another car as she was trying to enter the highway via an off-ramp. It happens very often. This started occurring at 60k! When stopped with your foot on the brake or even in park, the car goes slams backward and cuts the engine back to a rev. This has been occurring since 37k. Additionally, there is a loud clunking noise when you turn the wheel. This has been occurring since 50k. Power seat on driver’s side loses all power and locks. This has been replaced/repaired three times! Glove box locked and will not unlock even with key. All of these issues are frequently reported via complaint sites, yet no recalls on this very expensive car. It is truly a hazard!! https://www.mercedescla.org/threads/loss-of-power.40274/
