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.

Sensor malfunctions, battery power loss with complete electrical shutdown, faulty wire harnesses, locked up steering wheel while in motion on freeway, head unit defaults, faulty tires with blistering, countless recalls.

I bought mercedes cla 2015 on Jan 2015 and I drove the vehicle where my audio system used to reboot time to time once in a while but it used to come up. So I did not mention and take it to dealer that time but recently, after driving 53k mile, it completely stopped working and only rebooting itself. Later I found out there was recall about 2015/2016 cla audio recall "reference TSB no. 2015110001". So I took it to dealer "Mercedes Benz houston greenway" and they said they can not update unless they change control unit. I also called Mercedes Benz customer service but they also same thing. So I paid 50% cost which is $1457. This looks unfair to me because it had issue and it has recall too. I need proper help here as this does not look right to me and I am starting my voice here to resolve this issue.

I was driving on the access road getting ready to merge onto the highway. I proceeded onto the highway and made it into the middle lane going around 60 mph but shortly after my car threw itself into neutral and the dash lit up with three lines of words: the first line said 'service required', the second line said 'do not shift gears' and the last line said 'contact dealer'. I was able to pull my car over to the far left hand side of traffic. I turned off my car and turned it back on and it started with no issues. Since this incident though, I have had other electrical issues that have followed.

The contact owns a 2014 Mercedes Benz Cla250. The contact stated that while driving at approximately 55 mph, the entire instrument panel illuminated and the vehicle stalled.

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.

Purchased a mercedes cla 250c, and have had it became inoperative while driving on the beltway in washington d. C. Traffic, and more recently on the I-5 in san diego on 1/21/2017 during rain at speeds of 60+ mph in heavy traffic. The vehicle decelerated quickly and lost speed. The console popped up flashing message 'pre-safe functions limited' on the console. The vehicle did not respond to accelerator. After coasting to the right shoulder I was hit, by a passing car, and the motorist kept on going. This had happened about 10 time, and I bought the vehicle new. Mercedes aware, yet they would not do anything because they said if the engine light is not on we cant diagnose it.

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.

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.

While traveling at 50mph down a busy street during my morning rush hour commute, the vehicle cut off all power and went into "pre-safe mode" which is commonly known as "limp home mode. " when this happens, the driver has no ability to accelerate and if the driver is unable to pull over in a safe area, puts them at extremely high risk of serious accident. This is a common problem with many Mercedes Benz vehicles that are equipped with esp (traction control). A simple google search of this issue will validate this as a widespread major design flaw in Mercedes Benz products. Please take the time to look into this extremely dangerous problem, as many other mercedes owners have experience this in more dangerous circumstances (on the highway).

Brought Cla250 6/2015 after three months loss power, engine light came on car decelerated. Took vehicle to the dealership after 3 different incidents, to be told there was a service bulletin on my car. Will keep you posted after pick up. Car was at the stop light and the vehicle deceleration went down.

While driving my cla that I have only had 4 months the car turned off and said it's inoperable! I was almost hit multiple times, when dropped it of at dealer they wouldn't even give me a loan. I bought this car brand new!.

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.

I was driving on a busy surface street in los angeles when my car lost all acceleration and the message popped up, "inoperable, see manual". I tried to push the gas pedal to quickly move over to the right lane where I could put on my hazard lights but I could not accelerate. I turned off the car quickly and started it again and it went back to working for now. I am terrified for this to happen again, especially because if it happened on a los angeles freeway, I could easily be killed. I am 8 months pregnant and fear for my safety and the safety of my child.

The contact owns a 2014 Mercedes Benz Cla250. The contact stated that while driving at approximately 55 mph, the vehicle stalled after the inoperative mode warning light illuminated. The vehicle was able to restart but the failure recurred. The vehicle was taken to the dealer where the failure was unable to be duplicated. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 3,700.

What is the problem-pre safe malfunction error when does it happen-while driving is it predictable-no is it safe-no why-the car suddenly loses acceleration ,when the pre-safe error comes on. Scenario-driving a cla 250 at 60 mph on a motorway on a quiet road in front of a truck. . . . Pre-safe malfunction kicks in the car slows down and loses accln. The truck driver cannot predict this behavior a this is not a normal pattern to slow down suddenly from 60mph on a quiet freeway. Very very dangerous.

Driving vehicle home on I-95 southbound at night. The "eco" drive blanks out, a message "rescue" appears, the speed decreases until stops, even though the motor is running. If you turn the engine off, wait a minute and then re-start, you can drive it again. It happened eight times to me between fort lauderdale and miami.

Driving on interstate at 70-75 mph engine lost power without warning and speed reduced to 30 mph with no response from gas pedal. A semi ran up behind me and swerved to the fire lane. This is the third incident in one month. The other two were at 45 mph. Each time I was able to pull over and stop the car. Once it is started it runs at full power, until it decides to stall again. I had the car towed to dealership and will not drive again. I could have easily been in a serious accident. I am in discussion with gm at dealership to work something out. I will be unable to sell this car later in my opinion based upon the commonality of the problem, yet the dealer acted like they had never heard of it. I should have googled it first and then reminded them of the issue. This is unacceptable.

This is actually the third time that this happens to my car but this time I was driving on the freeway and it was a pretty scary experience. I was driving on the freeway at about 60 mph. All of the sudden, my car lost speed and power. A warning message showed on my dashboard reading "pre-safe functions limited see operator's manual" at this point my car was still running but at a low speed and I could not accelerate. I was driving on the fast lane of the freeway. I put my emergency lights on and likely the car behind me noticed that I was having issues with my car. I turned off the car, waited about a minute and turned the car back on as I had done this the other two times that this had happened. Once I turned the car back on, I was able to drive home. However this was a very scary experience as the car lost speed and the car behind me could have rear ended me. Another issue with this car is that the engine light has come on about 3 times in the last month after receiving a warning message "inoperative". Another issue "hazard warning flashers malfunctioning" I have left a message to take my car for service. I am waiting for a call back.

On September 10, 2014 and September 21, 2014, vehicle 'pre safe functions limited, inoperative' light comes on the vehicle and the vehicle loses power. Both times driving approximately 50-60 mph. First time driving on street and was able to coast home. Second time I was on major highway. . . . Very dangerous! unable to accelerate both times. Took vehicle into local dealership on September 11th, they were unable to replicate issue and returned car. Did not drive vehicle for 1 week due to travel, returned and within 2 days of driving the car, error message returned and I was unable to accelerate car. To get the car to function, must turn the vehicle off and back on and then it drive-able. Vehicle is currently back at the dealership for repair. This issue actually occurred several weeks prior but I did not report to the dealership because the light came on and quickly went back off. Also experienced slow acceleration issues when moving from a complete stop.

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.

While driving the vehicle suddenly the accelerator started to have a delayed response. Pressing the accelerator would not do anything for between 3 to 5 second after the car was stopped. After the delay, the car would respond and was drivable, but after every subsequent stop, the 3 to 5 second delay would return. This continued for the 20 miles that I drove to the dealership to have them look at the car and repair it. I believe this unresponsiveness of the accelerator to be a dangerous condition as it prevented me from being able to driving normally and could have prevented me from moving my vehicle if it was stopped and a situation required it to be moved quickly. At this time this occurred the following warning lights appeared on the dash. The check engine light came on. The esp warning light came on, the esp system "off" light came on, and a message stating that "presafe functions were unavailable" appeared on the dash board computer screen. This was the second time this happened to me. The first time was at the beginning of April. I pulled the car over. Restarted the car and the condition fixed itself. This time, restarting the car did not clear the condition.

Today I was driving in a parking lot and approached the light to exit and my dashboard lit up with a presafe system failure, system is inoperative and my car slowed down considerably when I tried to accelerate. I pulled over and turned the engine off and then on again and the error cleared. This is very dangerous if it happens on a highway or while driving on a crowded street. I called the dealer today and was told if the error was not currently on the dash they could not do anything. I explained that this was unacceptable and they needed to look at the car. God forbid I am on the highway and it disabled. Last week my brother-in- law saw the same car disabled in the middle lane of the highway. I hope mb fixes this problem fast before someone is seriously hurt.
