Strong gasoline odor inside the car. Dealer removed the rear seat. Removed left and right fuel tank access covers. Found suction jet pump area wet with gasoline. Found the fuel sending unit left side cracked and leaking. They recommended replacing suction jet pump and auxiliary pump costing $1,571. The smell is constant whether moving or not and regardless of location. I cough when driving the car hence I seldom use it. If I can not avoid using the car I open all windows and tell any passenger to avoid smoking to prevent fire. I started to notice this issue mid August 2020.

When the car is in idle and in motion, the cabin of the vehicle fills with a smell of fuel, and it was also discovered that the car also has began leaking from the fuel tank located underneath the rear seats.

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.

While driving at normal street speed "collision prevention assist inoperative" displayed and car would not accelerate. I was in traffic, but was able to exit and pull over and park, turned car off, & back on. Display reset and car normal. Took to dealership immediately-repair was "non connecting pins". too early to tell if this solves. Upon investigation, this is a common issue with 2014 mb and I want to document this extremely dangerous performance.

The car showed "pre-safe unavailable" and showed that the stability control off light on the dash. It went into "limp" mode just before a dangerous Y shaped intersection where I was turning to the left leg of the Y and the oncoming traffic was from the right side of the Y. the car was almost totally unresponsive to throttle inputs, and as I had to slow down to see down the hill to the right side of the Y, acceleration across the intersection was less than normal walking speed. Luckily, there was no traffic coming to the right or behind me. Dealer was unable to find the cause. I traded the car in for the next year model due to feeling unsafe driving it.

Car completely shutoff tonight on the highway and luckily I was able to get pulled over without incident. I had numerous messages on the display, including "service required, do not shift gears, visit dealer" and "esp inoperable, see operator's manual". the car would not do anything once I pulled over, nothing happened when I turned the key, no noises, nothing. Mb roadside assistance came and tried to jump start and disconnect the battery to no avail. So, off on the tow truck it went.

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.

This has happened multiple times starting in Jan. 2014 and most recently April 15, 2014: Come to a stop at red light (or stop sign) and when I step on gas to go when light turns green, etc., no power or, at most, car barely coasts to shoulder of road. It does not sound like the engine engages. I turn the ignition off and then on again and the car runs. This happens when eco stop/start function is on and also happens when it is off. I am afraid to drive the car because this happens without warning. I could be driving the car for a week with no problem and then it happens.
