While driving on the HWY the vehicle started to loose acceleration and make some strange noises. When I tried to give it gas I heard a loud pop and smoke starting coming out of the hood of the car and the exhaust.The car shut off in the middle of the hwy. With the moment left I got the car over 3 lanes to the shoulder. There were two of in the car that were at risk if this failure would have caused an accident. When I heard the car making noise and before the loud pop. I went through the cars on board computer to see if there were any maintenance messages or if the car had low oil or tire issues. All the on board messages were good and nothing indicated there was an issue. Then the pop and car shut down came suddenly. I had the car towed to a Mercedes dealership. The car is 10k over the standard 50k warranty. The Mercedes dealership indicated that a rod went through the engine the car needs a full engine replacement and new front axle. They asked me to provide them with proof of car maintenance which I did. The car was serviced regularly for oil changes and filter changes though with Mercedes parts. The manufacturer is unwilling to look if there is a defect that caused this since it is out warranty and wants the repairs paid out of pocket.

As I was Driving on and heard loud popping sound above me, when pulled over and investigate saw that the glass between the windshield and Panasonic roof had spontaneously cracked all the way across ( they were no othervehicles within the distance for it to an outside object hitting it). Plus I saw nor heard anything coming in contact with the vehicle

The vehicles sunroof is starting to separate from the vehicle were it closes. Glass is sticking up and the front of the car where the glass starts is cracking all the way across. The safety is that the glass can implode and cause damage to me (driver) or passenger, piece could fly off into traffic and cause an accident and it is unsafe to drive without a roof because of the elements. I have made an appointment with a dealership and reported it to Mercedes. There was no warnings prior to when it appeared other than a crackling sound when I closed my sunroof then days later it appeared.
