Without warning , the vehicle started to shake uncontrollably and was unable to reach a certain speed without the tremors. Very unsafe to drive
2014 Mercedes-Benz CLA250 engine complaints
Page 2 of 3: complaints 11 to 40 of 68, newest first, as owners wrote them.
Right air bag malfunction error and check engine light for crank case. This is a very common problem that mercedes explained to me and also told me to check back for recalls because their vni system will probably show one
While driving out of a driveway, a car pulled near my car. At that time, the car was stationary. My wife heard the pre-collision warning. The the car completely shutoff or stalled. Turned off the car completely by turning the key. Then turned the car back on. Lucky there was no accident.
When the vehicle is stopped I can hear a knocking noise coming around the water pump the car has only 39,000 miles
I had a check engine light come on for a crankcase vent valve defect issue, the part is $750 and costs $1,950 with install. Upon identifying the issue, I spoke to the parts department at mercedes and they said that they have been replacing so many of these parts that it should be a recall on the c class and cla class. Most are repaired under warranty so it has not received a lot of focus. Mercedes is charging exorbitant rates to fix an error that they knowingly ignore to be a significant issue.

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.
Tl* the contact owns a 2014 mercedes benz cla250. The contact stated that while at a stop light, the vehicle stalled without warning. The vehicle was restarted and was driven to the residence. The contact stated the vehicle was later taken to mercedes-benz of encino dealer, (16721 ventura blvd, encino, ca 91436) where it was diagnosed, and the conductor coil was replaced however, the failure recurred. The vehicle was taken back to the same dealer however, technician could not find a failure. The contact was informed by the technician to drive the vehicle with the echo off. The vehicle was driven with the echo on and the failure recurred. The contact call the same dealer and schedule an appointment. The manufacturer was notified of the failure but did not assist. The approximate failure mileage was approximately 60,000.
While driving the car shuts off without warning. After the engine shuts down, it will start after waiting for about 1 minute.
Tl* the contact owns a 2014 mercedes benz cla250. The contact stated while driving 25 MPH, the vehicle shut off. The contact stated the auxiliary battery light illuminated before the vehicle shut off. The contact stated the vehicle was towed to the dealer (mercedes-benz of alexandria: 200 s pickett st, alexandria, va 22304) and repaired the conductor plate which caused the vehicle to stall and shut off. The manufacturer was notified of the failure. The approximate failure mileage was 14,000.
The coolant pump fails after about only 48000 miles, which causes the engine overheated. I did my research online and found that many others who own a mercedes cla 250 had the same coolant pump problem at low mileages (less than 50000 miles). Thus, I doubt that this coolant pump failure is a defect that needs to be recalled for. My car is still with the dealership so I do not have a report/receipt from them stating the problem yet.
I was driving my car when all of a sudden the car slowed down and the steering became stiff. The pre safe light came on the screen along with "parking brake" "traction control" although the parking brake was not applied. I had to have my car towed home because it was unsafe to drive.
Driving on highway in left lane doing around 60mph and car goes into limp mode taking away all throttle control. I was forced to coast across lanes narrowly avoiding a collision and managed to pull into a bus stop. I learned that limp mode is to protect the car from further damage but the safety of the driver should come first. There should at least be some kind of advanced warning to pull vehicle over before it shuts down. This is completely unacceptable and endangers the life of the driver and other drivers on the road.
After having 40k service about 6 weeks ago on my 2014 cla250, 'service required: do not shift gears, visit dealer' light came on from a parked position. Thank goodness I was parked! I've read several posts where this happened while driving at high speeds! This is a very dangerous occupancy... A critical failure! Anyway, the error message came on when I started the car and the car immediately shut down. It had to be towed on a flatbed as there was no way to even start the car and is at the shop now. My car has less than 42k miles. This really is unacceptable and I am scared to drive the car now after reading it happens while driving too! I haven't read anywhere what the actual issue is, only that after sone people get it back after a software update it happens again. Mb really needs to find out what is causing this critical error and fix it since it is so dangerous!
Purchased my new cla250 in september 2014. In august of 2015 my car suddenly stopped accelerating while driving 65mph on the nj garden state parkway!. The pre-safe warning was present on my dashboard. Luckily I was able to pull to the shoulder without causing an accident. This could have caused a major catastrophe killing me and others. I restarted the engine and drove to my destination making sure I stayed in the right lane on the parkway. It failed 2 more times while not on the highway but still a very dangerous situation. Took the car (which had 16,000 miles) to a mercedes dealership when I returned and they performed a series of tests. They found a product technical support system update which involved updating the software. The failure did not occur again until nov. 2017. I almost got hit by a bus in philadelphia when my car decided to stop accelerating. Finally, driving to the airport doing 70mph the car again displayed the pre-safe warning and rapidly slowed down almost causing a crash on I-78 in nj. Took the car to a mercedes dealership near me and they said since the car is 2,000 miles beyond the 50,000 mile warranty it's not covered. They are replacing a series of parts that will cost me over $4,000 to repair! There is no guarantee this will even fix the problem. Is mercedes waiting for someone to die before they acknowledge this car has a very serious problem? I have to wonder if there has been any crashes involving this car and nobody survived to detail what was happening! The 2014 cla is not safe and mercedes doesn't appear to be concerned.
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
Water pump failed, 21,000 miles
Vehicle became inoperative while driving on a highway. Happened twice today on speeds of 60+ MPH in heavy traffic. Vehicle decelerated quickly and lost speed, I was lucky to avoid collisions. The console popped up flashing message 'pre-safe functions limited' on the console. The vehicle did not respond to accelerator. After switching the ignition off and on again, the problem temporary disappeared, but then happened again. The vehicle is duly serviced and is still on warranty, there was no accidents or mechanical faults prior to date. Scary and very dangerous. Could have easily injured myself or someone else who would have hit the vehicle which suddenly becomes inoperative.
My car was purchased 8/2014 from mercedes benz of henderson nv. This car has had problems the1st day of owning it. This car has been in and out of the shop so many times that I have lost count. I have a folder as thick as my bible. Mercedes won't claim it as a lemon and this car has been in the shop for the same problems with additional problems every time it is taken in. The dealership will not exchange it for a equal car without the option of renewing another lease and increasing the payment. I have experienced hazard lights on the first 30miles. The electrical went out/warning flashers/malfunctioning/inoperable the car has died driving which put mine and others lives in danger. All I'm told is I am sorry. I am drained with dealing with the dealership and going through all of their turnovers with mngmnt. Pablo rodriguez was a gem along with butch who did nothing!!every code that was dcmntd was deleted from the memory. My car was recently in again with inoperable/malfunctioning display/acceleration/pre safe system error in which they said they fixed but less the 24hrs the same problem occurred. The dealership had my car from june 24th to july 10th and same issues but new error messages. I have been without a car since I picked it up and the dealership will not do anything about getting it in sooner then the 25th. They don't care at this dealership nor does mercedes corp. Hrs & hrs of wasted time talking to people who can do nothing.no calls from anyone, I received surveys in the beginning that were never addressed I know that because of my feedback. Ive never experienced anything like this before and it is so disappointing. Overall it has a been the very worst experience that ive ever had owning a car!!! Or mercedes that is.
Tl* the contact owns a 2014 mercedes-benz cla250. While driving 50 MPH, the check engine and RPM warning lights illuminated. In addition, the engine made a loud unknown noise and the vehicle began to lose speed. The failure recurred three times. The vehicle was taken to the dealer where the fuel pedal was replaced; however, the failure recurred. The manufacturer was notified of the failure. The approximate failure mileage was 1,000.
On multiple occasions, the vehicle will shut off while driving. The message states "pre-safe functions limited". When the car shuts off for no apparent reason, I have to coast to the side of the road to safety. I have turn the vehicle off and then I will be able to restart the engine. I've already taken this into my mercedes dealership and they did not fix the issue. I'm afraid this is going to cause a fatal accident and I have two small children. Please make this a high priority
Bought brand new cla250 a year ago and driving last week on the high way and "inoperative mode" went on and you lose all acceleration power. After I pulled over finally restarting the car a few times I regained acceleration. Currently at dealer being assessed
Bought the cla 250 brand new in 2014, vehicle has now twice gone in to pre-safe mode and inoperative mode while driving. The car switches to neutral as I am driving and then refuses to shift in to drive or reverse leaving me stranded in the streets on two occasion which could have caused two very serious accidents. The car on the second time had to be towed to dealership who could'nt find anything wrong with the car. There solution was more of a guess about a cpu needing to be replaced.
Car has now twice gone into pre-safe functions limited and inoperative mode (simultaneously) while driving with no notice, effectively removing all ability to accelerate and creating near major accidents both times. The first time occurred on the freeway driving in the second to the left lane at approx 75 MPH. Cars narrowly avoided crashing into me while I coasted through high speed traffic to the shoulder. The second time was in town and without warning same thing occurred leaving me coasting in the left lane with a truck narrowly avoiding a collision and the truck having to go into oncoming traffic and back to avoid me. As there was no shoulder I had to navigate and come to a stop in the right lane of traffic.
Tl* the contact owns a 2014 mercedes benz cla250. While driving at approximately 65 MPH, the vehicle stalled and the engine warning light illuminated. The contact was able to restart the vehicle on the first attempt. The failure recurred intermittently. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 25,000.
I was driving on I-85 at 70 miles per hour. The car stop accelerating and on the dash board a message of inoperative, see manual. I was almost hit by many cars. I coasted to the side of the interstate. I almost freaked out. I called the mercedes dealer and I was told to cut the car off and turn it back on. That didn't work. I had the car towed to the dealer. The dealer told me they did some updates and fixed the car. The car did the same thing 2 other times. I could have been killed in the traffic. This time I took that death trap back to the mercedes dealer and left it and informed the dealership to give me another car or give me my cash money back that I paid for the car. I am not taking the car back. I am afraid I will be killed in the car. This is the most scary experience. The dealership told me that there is know fix for this problem the car needs to be grounded before someone get killed.
Recently, every time I ma driving in the rain, no matter how light the rain is, the traction control light comes on and a message stating"pre safe, functions limited, inoperative" shows up. The vehicle has looses acceleration. This happened to me on the freeway today. This is potentially dangerous as it could cause a serious accident. This seems to be a recurrent problem based on a simple online search.
Inoperative - pre-safe functions limited - I've had this error come up 3x so far, it happened 2x just last night on a 10 minute drive. First time was on the freeway, had to pull over to the shoulder and restarted the car. The 2x other times happened last night, driving 10mins in the evening, both had to pull over and restart. The second time, my check engine light came up. I hope this is addressed quickly as I can see that the complaints are piling up on here.
Inoperable message flashed on the dash as I lost all acceleration power. Was almost rear ended by a semi, but was able to pull over to the side of the interstate. Luckily I was not in heavy traffic at the time and didn't get hit. This has happened 3 times now and I am still waiting for mb to get back to me.
Was driving down the road, the car started hesitating, and lurching repeatedly. I was just able to pull into a parking lot off of the busy street that I had been driving on. Once in the parking lot the engine totally died and a message of "inoperable" appeared on the message screen. This required towing of the car to the dealership. It was determined that the intake manifold pressure sensor was faulty as well as the crankshaft position sensor was faulty. Electrical investigation revealed that a ground stud on the chassis was painted over and not making contact. Update of software, cleaning of contacts, and replacement of sensors resulted in smooth running engine.
