Battery Warranty

[JodyS21]

Just a thought for you guys out there that are having very very low battery capacity issues.

https://mg.co.uk/files/2019-06-26/MGZSEVWarrantyStatementv1.pdf

I know there's a whole discussion going on about the battery usable capacity, however.
According to the warranty:

During a capacity check at an Authorised MG Repairer if it is determined that the lithium-ion high voltage battery has suffered a capacity drop below 70% of the original value at delivery of your new MGZS EV, the segment below 70% will be deemed excessive loss. Where possible the excessive loss portion will be repaired, if un- repairable the lithium-ion high voltage battery will be replaced with either a new or a remanufactured battery.​

The car is delivered with a specified 42.5kWh battery - regardless of gross/net/usable capacity.
70% of 42.5kWh is 29.75kWh

So if you're one of those experiencing massive degradation and you believe you're getting less than this in usable capacity. Surely you are within your right to tell MG to either repair it or replace the battery (or even the car).

I've already tried this one. Extract of their response....
-----
"We are not going to replace the battery.

As long as the updates have gone in, the car will recover. I appreciate that it has been inconvenient and will continue to be so until fully recovered, but it will recover."
------
I think they are out of order. They damaged our cars and are expecting us to just suck it up at our expense and inconvenience. There is a growing pool of dissatisfied customers and telling us to take a hike isn't helping their cause.

I completely agree that is an unacceptable response.

"Where possible the excessive loss portion will be repaired"
Telling you to go home and keep using the car and it will fix itself, is not them repairing it as per their warranty.

The lowest I recorded was 429V. It's now up to 440V, but that has taken a lot of charging. The range has increased (in these winter conditions) from 45 miles to 65 miles, where I would have received at least 110 miles last Feb.

OMG
Instead of your expected 110 miles, you were getting 45 and now only 65 still!!!!!!!!!!!!!!
That is absolutely awful.
I do not know how they could have just given you the car back in that state without replacing the battery or something.
I would be sooo mad if I was you.
Have you tried taking it to another dealer or trying to talk to MG direct. That is completely unacceptable.

I haven't tried another dealer or MG direct (don't know how to contact). I thought I'd follow their advice first. I am seeing an improvement, but still a long road (with many charges) ahead. I'm annoyed that it's my responsibility to sort this out, at my cost and inconvenience.

Hi Trevor,
You can contact MG UK at the above address.
I too think you have had an unacceptable response from your dealer and would let MG know you are dissatisfied.
I always remind companies that if I do not receive a satisfactory solution to an issue I will highlight the problem to the media. Bad publicity is not something that companies wish.
Good luck and hope (for all of our sakes) you get this resolved.
Regards,
Iain

Thank you Iain. I did tell my dealer they can follow my progress on here?. They are just the middle man so I'm not outing them (just yet).

@Trevor .
Seriously, you need to speak to MG customer services mate.
Even at best now, you have lost almost 50% of the range that you was seeing last year.
That is clearly not acceptable by any bodies standards.
I would just state your case to MG CS and ask THEM what they would advise towards a way forward.
You have followed the instructions from your dealership and YES you have seen an improvement, but the car is still falling WAY short of what you know is achieved by other owners.
You are not looking for anymore than other customers are receiving ?.

Thank you Iain. I did tell my dealer they can follow my progress on here?. They are just the middle man so I'm not outing them (just yet).

The dealer may be the middle man in terms of the supply chain but they sold you the car and as a consumer you have rights and the dealer has to supply you the vehicle that was advertised. It has to meet the quality standards expected. I posted a link to the consumer rights when buying a new car in another topic on this forum. I used one of the template letters and the dealer that sold me the car is doing all the recharging and dissipation until the battery is fully restored. They said it can take up to a month and in the meantime supplied me with another vehicle.
