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.

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.

My sister was driving across town and came across some uneven payment near a construction zone. She hit a small-medium sized pothole and it somehow triggered both the front and rear passenger airbags to deploy. There was no damage significant impact when it happened and no damage to the exterior of the car (tire, wheel, fender). It happened today (Saturday) so it was taken to a local independent repair facility. Will know more Monday. Parts available for inspection upon request, of course.

While driving the other day I opened the sunroof when it suddenly made a strange sound and stopped. When I tried to close it I noticed that the left side was raised but the right side was down. It made a whirring sound and moved a little but refused to close. When I got home and looked at it it looks like the windscreen has come loose and looks like it was pushed forward and broken by the linkage that makes the roof go up. It looks like the linkage is bending forward when I suspect it should bend backwards. This has been happening since I bought the car in 2016. Sometimes it opened and while driving I'm afraid it might blow out into the high way. Causing an accident

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

My son had to be cut out of the seat back because it was too tight and wrapped around him. The seatbelt strap was locked and would not extend out at all to loosen for extra length on the strap. The seatbelt strap was so tight my sons stomach was was cinched to the point where he couldn't breath. I'm not sure why the suspension on the strap was locked every other seatbelt had extended strap. This was a scary experience and could have severely hurt my son. This is unacceptable for the price I paid for this vehicle and not to mention my child's safety. I didn't take any pictures of the strap around my sons stomach because he was in pain and was frantically trying to get it loose and cut. I have pictures of where I had to cut the seatbelt. I also have a defect with my electrical which I causing my battery to die. The car will stay on completely without the key in the ignition or started. I have video of that as well. This is completely ridiculous for a luxury vehicle. My main concern is the safety of my passengers andy son simply unbuckling a seatbelt and getting strapped in because the suspension of the strap would not loosen and was locked is unacceptable. I tried everything to putting the car in drive pressing the brake to see it the strap would unlock and nothing worked. My son was in pain because of this defect O had to cut the seat belt strap off frantically. This is not okay!

My class C 250 2014 vehicle. Diving long distances on the interstate started hearing loud static over the speaker system. The radio was not on. The noise turned into a loud screeching/ static noise from speakers with an electrical burning smell filling the car's cabin. I pulled off-highway, turned the car off, the noise/ burning smell did not stop. I let the car sit for about 1 hour. After the car was turned off for 1 hour, the noise /burning smell stopped. This has become an ongoing issue; I have taken my car to the Mercedes dealership. They have stated it could be the "star service" electrical problem, but no guarantees; in my complaint, there were no rectifying of on issue. My fear is electrical fire, while traveling. I commute by interstate daily.

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.

Last week on March 31st I went to turn my vehicle on since I wanted to move it from my parking spot in the neighborhood to my garage in order for me to go to the grocery store shortly with my 2 month old baby. As soon as I put the key in the ingnition slot and turn the key I heard like a zapping noise instantly and noticed in a matter of seconds smoke coming from underneath the steering wheel area. Sort of near the floor os the drivers side. I immediately hop out of the vehicle to see what had happened and where the smoke was coming from and just as quickly flames started coming from the same area as the smoke. I called 911 and in less than 3 minutes the entire inside of the vehicle was in flames, burning down. The flames then blew all the windows and moon roof trying to escape the vehicle and by the time the fire rescue came most of the vehicle was gone. I thank god I didnt get to move this vehicle as I had originially planned because it would have cost me my life and my families. I owned this vehicle only about 3 years and it never ever gave me problems. All of its maintanance was up to date and never had any electrical issues or major repairs due to anything. I am almost certain this was a fuse or electrical problem that caused the vehicle to burst into flames due to the zapping noise I heard as the vehicle was being turned on. I had been driving this vehicle perfectly fine which is why this came as a huge surprise. I want to make sure others are aware of this issue since its a huge risk. My specific vehicle has never had any recalls and im always checking and up to date with everything. I will be contacting the Mercedes Benz manufacturing company to let them know of this as well.

Air bags: Frontal- sounds like the airbag lock spring is broken for no reason. I can hear the click when I turn. The digital dash reads "front left malfunction" and won'Y go away no matter what I push. It also has an electrical system: Starter assembly issue- the engine or transmission won't turn over a lot due to it. My car only had 40K miles.

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.

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.

Pre safe functions limited light and inoperative traction control light comes on car immediately loses 50 percent power and will not accelarate. 15 times in a 1yr period. Dealer doesn't see a problem..today for the 5th time I was nearly hit by an oncoming vehicle. Two weeks ago problem occured while I was in a funeral procession going through an intersection the vehicle behind me had to swerve to avoid a rear end collision..I do not feel safe driving a car I paid 50,000 for..

- Pittsburgh, PA, USA

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.
