What 284 owners told NHTSA about the 2014 Mercedes-benz C-class Phev

The driver's side interior door handle became disengaged as I was trying to open the door so I was momentarily trapped inside. If I had been in a situation where I had been in an accident and needed to get out quickly, or the car had been on fire, or I was stalled on the train tracks, this could have been a serious incident. When I googled this, it sounds like this is a very common occurrence in Mercedes. There was no warning that this was going to occur - everything seemed secure before this happened. I have taken it to a service center for a very expensive repair as they have to remove the door panel, replace/reattach the part and put the door panel back.

The passenger airbag was replaced under the Takata recall. Recently the airbag indicator light came on for the driver airbag. We have been notified by the dealership that this airbag needs replaced. They provided an estimate of $2,652.29. We reached out to Mercedes due to this being a safety issue and also due to the fact that the passenger airbag was replaced under a recall. They are unwilling to assist. It is illogical that just the passenger airbag is faulty in the recall but that the driver's airbag is fine as they came from the same manufacturer and installed when the vehicle was built. We are concerned about either deploying on its own or if it will deploy in an accident.

1. the component that failed was the front stationary sunroof panel, and what failed on it was the adhesive which leads to it leaking water, and the potential of even falling off while driving 2. it could lead to falling off on the highway which could lead to damages to it or other vehicles around it 3. Unknown 4. Yes it was inspected at a nearby dealer ship in which they stated that the glue was failing on that part of the car and would need to be replaced 5.

I prchased used with no visible damage to the windshield. In the inclement weather for no apparent reason my windshield began to crack as I was driving the vehicle. I pulled over as soon as I could. The crack stoped and I called the Mercedes Benz manufacture to no avail. I decided to research to see if this is common and the article says, "that the 2014 Mercedes Benz" windshields are known to crack in extrem cold and hot conditions. The windshield has continued to spider and crack in different direction. I feel threathened at this point and featful for my life that this will implode in my face while driving. I did in good faith reach out to someone.

I was driving my vehicle when the transmission started shifting erratically. The shifts were not smooth but hard and the car was shuddering. Yes the vehicle is available for inspection. My safety and the safety of others were at risk due to the erratic behavior of the vehicle and how it affected my ability to focus on driving safely. Yes my vehicle has been inspected by the manufacturer and the problem has been reproduced by my local Mercedes Benz dealer. There were no warning lamps or messages prior to the failure. After a few weeks of driving I saw a “low coolant” warning appear, this turned out to indicate that the radiator had leaked coolant into the transmission which damaged the internal transmission components and torque converter.

Mercedes has a convenience easy enter/exit feature that lifts the steering and slides the driver's seat back for easy exit and restores the seat and steering when the driver sits down and places the key in the ignition. The safety issue is the steering often gets locked in the up position and doesn't lower, making it unsafe to drive the car. This is happened 5 times since I bought the car. I had to drive home with the steering wheel locked above the dashboard. The car has been towed to the dealership 4 times under warranty and now I have to get it towed myself. There are approximately 54000 miles on the car.

I was in an accident that caused my car to be a total loss. I was hit near the front left side, close to the driver's door. The airbag did not deploy despite the hard impact. I am currently having to go to therapy due to impact. My right lower arm was bruised from the impact, and I was in a lot of pain due to the bruising caused. I am assuming the bruising came from the hit to the steering wheel. I was never notified of an airbag recall.
