Check Engine Light On Problems of Mercedes Benz CLA250

While merging onto the freeway on 1/22/2021 the car's dashboard displayed "collision prevention assist plus inoperative " and the check engine light come on. When this happened, it prevented me from accelerating the car by pushing onto the gas pedal. This caused the car from behind to almost rear ended by car. I was able to drive onto the shoulder of the freeway and exit the freeway. I have taken this car to the mercedes dealership for repair but it is an ongoing issue even after various parts have been replaced.

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.

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.

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.

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.
