Apparently the TPS (Throttle Position Sensor) which is built into the gas pedal on this 2014 MB CLA250 only lasts so long before it becomes defective under highway conditions and causes the vehicle to go into LIMP MODE. When full acceleration is necessary, the unit will work for perhaps a few months or less, and then continue to fail worse and more frequently with each attempt at full acceleration. At highway speeds, this is an essential feature in a 4-cylinder vehicle such as this one and without the necessary acceleration capability, can expose the driver to serious risk of collision with other on-coming vehicles traveling at highway speeds. This "Limp Mode" features is extremely dangerous and hazardous to not only the driver of their vehicle, but to other drivers around them since they are left in a devastating position of being unable to accelerate normally and as necessary and as one would expect in any vehicle, let alone a Mercedes Benz. Never before have I driven a car that falls out of full acceleration mode only to subject the driver to serious collision circumstances. Whoever the imbecile is at MB engineering who incorporated this Limp Mode Feature should be fired!!! To make matters worse, this cheaply built TPS, which is the cause of the problem in my vehicle specifically, was only warrantied twice by the dealer and now they will not replace it under warranty which is a two-year period. I've only had the part 5 months before it failed again due to poor manufacturing and I had to pay all over again for a new one despite my warranty validity. I note that there have been many other MB owners who have the same complaint regarding Limp Mode experiences, which tells me that it's definitely not me, but rather the poorly built or engineered vehicle, as a matter of fact. MB has denied having these complaints to me, which of course, is a lie. That's misleading and deceptive business practices in my State and MB needs to live up to its warranty provisions and respect its customers without trying to save a buck at their expense and safety.

My 2014 CLA250 almost caused me to have an accident yesterday. I had been noticing that the car would jerk or hesitate on occasion and was told by an authorized Mercedes mechanic (not the dealer) that the car's software probably needs to be updated. While driving around 45 MPH in heavy traffic, the little yellow engine appeared suddenly on the dashboard and the car behaved as if it was going to shut off. Thank goodness, I was able to get home safely. After reading similar complaints on this website and other sites, this "limp mode" behavior is extremely dangerous and unacceptable!! I have an appointment for service at the dealer in two days. I am going to try to trade it in as soon as possible.

Thank the good lord I was able to swerve like a BOSS. MY 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. TOOK MY CAR TO Fletcher Jones Motorcars | Mercedes-Benz AND THEY CLAIM THERE IS NOTHING WRONG WITH MY CAR. THERE WERE NO ACCIDENTS OR MECHANICAL FAULTS PRIOR TO DATE. VERY SCARY AND VERY DANGEROUS. COULD HAVE EASILY INJURED MYSELF OR SOMEONE ELSE WHO WOULD HAVE HIT THE VEHICLE WHICH SUDDENLY BECOMES INOPERATIVE.

If anyone would like to get in contact with me about their 2014 CLA 250 aka DEATH TRAP on wheels please join me on Facebook. I'm trying to start a Facebook group to get attention on the horrendous things mercedes is trying to do to keep this quiet. I don't think they'll do anything until someone dies and I'm not going to sit around and wait for that to happen.
