    Hi all,

    I purchased a E350e a couple of weeks ago and so far it has spent 90% of that time on a ramp at my local dealership.

    I was so excited the day the car arrived. I jumped in, took it for a quick spin, messed about with the gadgets and drove it back to the office on charge mode to get the battery level up.

    I arrived back at work and as soon as I came to a stop, a warning light came on saying ENGINE MALFUNCTION - DO NOT TURN OFF THE ENGINE - CALL MERC NOW.

    So I called recovery - they turned the car off and....it wouldn't come back on again. It got towed the same evening that it arrived. I could have cried.

    It then spent 2 days at Mercedes. I called and asked how it was going and they informed me that they couldn't find any faults or issues and the car had started first time and continued to do so every time they tried. So, i collected my car that afternoon with a big grin on my face, thinking it must have been something I pressed/did and that it was just one of those things...

    I got the car back to the office again, plugged it in to charge and when the battery got to around 80% I got an error message. I unplugged it all and plugged it back in (common IT fix) and it errored again. I got in the car and tried to start it up only to be greeted by the very same error messages.

    Once again, the car was towed to Mercedes. I called them a day or two later and they informed me that they no longer had a Hybrid Technician so the car would have to be moved to another dealership. This was on Wednesday last week and as I sit here now typing this, it is where the car remains.

    My conclusion is that its a battery issue as I believe I got to about 80% charge on my first trip out and then again when manually charging. I had to tell Merc my theory as they had no idea - and they agreed.

    Has anyone else seen or heard of an issue like this and is it an easy fix. I guess my actual question is - will I get my car back?

    Sorry to be a doom and gloom merchant, but if you do a search on here you will find that there have been many such problems with MB Hybrids. Some have had their cars replaced as their dealership couldn't fix them.

    Just to balance things up though most or maybe nearly all have been the non plug in early hybrids, less reported on plug ins..
