Today I was at the drive thru getting some food. I feel a pop from the rear and I thought the car behind me rear ended me. I walk outside and the car is still far away. I walk back into the car and notice that the car shut off. I try to start the car again and it just keeps on cranking. Eventually the employees of the restaurant have to help me push the car into the parking lot to wait for AAA. Going to call Mercedes Roadside assistance in the morning.

Anyone else have this problem? I was thinking it was a fuse blown by that sound but all the fuses look good.

Wow that must have been embarrassing. No excuse for that happening.

Sorry to hear that.
Try not to go to "drive thru " next time. Perhaps Fast food is not good for our cars ))

Completely inexcusable for a brand new car... I would demand an exchange... who knows what else is bad in there..
Pl keep us updated.

jesus christ man.........

this sux........keep us posted eh?

I hate to hear that! 5000 plus miles on my car in less than 3 months! No problems!! **Note to self Mercedes Hates fast food** LOL

Check your glove box and center console to see if the factory supplied jar of Grey Poupon has been properly installed. My gut feeling, based solely on how trouble free my E350 Bluetec has been, is that this is something really simple. No idea what could have given you the sensation of being hit from the rear unless it was exhaust related. When I purchased mine, I made the dealership promise me a Mercedes Benz, and, so far it has lived up to the promise. Keep us posted.

It's probably coincidental, but they did tell you during your pick up orientation to the car that you had to put fuel in it.

(sorry...just couldn't resist....this is my evil twin forcing me to type this note)

It should be something simple but why didn't you call MB roadside assistance right away? That's why they are there....

It was the Flux Capacitor

Bummer. At least you were not caught in rush hour's stop 'n' go traffic.

!!!!


Nothing like a little humor to help ease the pain of a total Benz Breakdown.

faulty fuel pump should get the car back tomorrow. This is crazy less then 600 miles and dead fuel pump

under warrenty right??
but still, they should buy you a T shirt or something to help
soften the blow....something!

It is not a common occurrence, but, new parts can go bad right away. As I have not read any posts of others with bad fuel pumps, I would suspect that this is an isolated occurrence. I feel the OP's pain, but, these things do happen, and it is a simple fix that will not likely cause any other issues. I hope this is the biggest problem the OP encounters.

Well they put in the fuel pump today and the car started and ran. What they found out was that the fuel line was leaking causing high pressure that blow out the fuel pump. So now they have to special order the fuel line from Germany.

I'd be pretty pissed if that happened. That's the thing with direct injection - cutting edge german engineering coupled with low quality chinese manufacturing just don't mix. It's downright scary when you're running a multi-hundred PSI component in the car. If you've ever had a intercooler hose let go at 22psi you can appreciate how much pressure the fuel is under.

The current 3.5L is not D/I though.

How can a leaking fuel line cause HIGH pressure?

For a bad fuel pump? I guess you can demand anything. I have found that arrogance generally does not help much when resolving issues. Demanding a new car because of a failed fuel pump is likely to land you on the "wack-o list".

Lets be realtistic folks, no one is getting anything free (Ok, maybe an oil change), outside of that, ish happens...
