Battery End of Life

[stevemcsherry]

My Hybrid e300 refuses to switch from Diesel to Electric and I am advised that this is because the battery is end of life, however the car is only six years old and has only completed 40,000 miles how can this be ?, the bill for a new battery on the Hybrid is too say the least expensive but surely should not need renewing yet ?

Which battery are they alluding to ?

 

[stevemcsherry]

No idea yet just recovering from the shock of being told it could run into thousands of pounds to repair !

Holy moley

Good luck with that

Apparently the Mercedes warranty for traction batteries is 6 years or 62,000 miles, which seems poor compared for example with Toyota's 10 year/150,000 mile deal.

Sorry to hear that, how much have you been quoted?

That's why I'm sticking with my £Eco M113K V8.

It’s pretty annoying when the battery in your phone goes end of life, must be very annoying when it happens to the hybrid battery in your car. Until the OEs properly land this, it will be one of the elephants in the room on battery powered vehicles.

I would be sceptical of the diagnosis that you have received. The battery on a EV or hybrid will of course deteriorate over time, usually this shows up as reduced capacity and hence reduced range. If there has been a sudden catastrophic failure of the battery (or part of it) then that would be pretty unusual. If part of the battery has failed then it may be possible to repair the battery rather than replace the whole thing. I'm not sure where you have had the diagnosis from but I would be seeking a second expert opinion from a HEVRA independent specialist before spending thousands on a new battery pack. In the worst case I would not replace the battery anyway and just run the car as a e220 diesel.

 

[stevemcsherry]

Thanks Smiley you echo my thoughts exactly and my next move is a second opinion as it has given no indications of any issues over the last 12 months suddenly stopped working.

Nothing yet just been to local garage to have a systems check to find the fault and been given indicative cost for replacing unit, so will now take it to a local specialist Covid permitting.

If that is correct then good news as the car is not five years old until next week and well below mileage so local dealer may be first call tomorrow

Who diagnosed this issue, was it a main dealer?

If so then they are fully aware of the warranty.

If you have taken this to a garage of your choice, then obviously that is your choice and it is our choice to check what qualifications an independent garage has. Yes, without a shadow of a doubt there are independent garages that spend lots of money getting trained in the latest drivetrains but these are a very small minority. If you have allowed non-qualifird mechanics work on your pride and joy, then that is your decision and should you be liable for those costs?

If I were Mercedes and I offered this six year warranty, I would make a condition that the vehicle has been properly serviced by a main dealer, why should the manufacturer be liable for non-qualified technicians working on these complex vehicles.

No doubt you have had the car serviced by a main dealer and I would simply remind them of their warranty and why are they trying to 'fleece you'

There was a thread about a failed HV battery on an E300h a while back (same power unit etc). After much to-ing and fro-ing and some scary estimates, it was eventually fixed under warranty. It was a hard fought victory though. The quote was something absurd like £14k for the battery assembly.

As with a lot of upmarket car makers, they've done something because they can, not because it's better ! Electric cars are nowhere near developed enough to be marketable ! As for saving the planet, we're told we now need two EVs, one for town and another for distance, what kind of logic is that ? My heart goes out to you, being kicked in the teeth for trying to do the right thing.

Spoke with Mercedes who confirmed warranty covers it. Now booked into main dealer so will be interested in what they have to say.

That’s a result! I hope they sort it out for you...

Who told you that?
