Hybrid battery failure

redfarmer27 · Sep 14, 2023

Range Rover Sport, 2015 diesel hybrid. Battery has been diagnosed as failed, new replacement more than the value of the car. So I will have to scrap a beautiful car with only 59,000 miles on the clock, a car that would easily have lasted for 150,000 miles if looked after. The electrics are all linked up apparently, so I cannot even use the diesel engine on its own. How is this good for the environment? How is it even economic? Be warned - if you buy anything with a high voltage hybrid battery (probably including any PHEV/MHEV as well as my HEV) then don't expect it to last beyond 60,000 miles.

Sorry to hear that, battery cars are a big con even hybrids.

It's probably only one or two cells. There are companies that will diagnose properly and replace just the faulty cells.

It can also be a sensor failure, so the system thinks the battery is bad.

Read this thread. Lots of people with same issue. P4 has a link to UK company that repaired for one poster.

Welcome. I'm not techy enough to advise. But, I have to admit to being in shock at the "easily lasted 150, 000 miles, if looked after".What happened to 150k being 'just run in' for higher marques? This is a sad reflection on modern, so called green cars. If looked after, which she is, I expect my currently 21yr old, approx 150k miles, Range Rover to live another 21yrs. With possibly one more gearbox. My 7 series Volvo was traded at 199,998 miles, with plenty of life in her. All my other cars, with the exception of the TR7 were expected to do over 200k and keep going, so long as they were looked after.
Surely those are much greener than 150k , if you're lucky. Not a dig at you, just at so called green credentials from manufacturers.*

^ which we all know is bull considering the damage caused to the earth to produce the batteries.

Thus it begins....

Hydrogen or diesel is the way forward....

As I mentioned on another thread, the AA guy was kicking off about a 3 month old Tesla that had died on recovery. Went from 40% to 0% whilst sat on his truck. Luckily still in warranty as £23k for a new battery. Ouch!

I would get a second opinion if possible and as suggested there could be a business that could help. Such a shame..
Ticking boxes and saying our vehicles can do this is only a plus for the manufacturer and a serious negative for any consumer...

Good luck with your venture

People need to understand that cars, just like all else, are disposable items these days. Technology is such that components can be designed to last for a specific period of time.

I have a RRC that is 36 years old & BMW at 25 .. so I guess I'm bias

+1 to that. I have 22 & 23 year old P38's, a 20 year old Transit and a 37 year old Toyota all still going strong and I expect them to still be running when I have popped my clogs

I thought most of hybrid and EV batteries have extensive guarantee, mainly because of disposal concerns.

Typical ill-informed comment.
Hydrogen ICE isn't even worth bothering with in a passenger car, unless you want a vehicle with a 100 mile range. Diesel puts out UFPs, which are far more damaging to air breathing creatures than CO2.

The battery can be repaired or replaced with a second hand one.
A modern RR is just as likely to suffer engine failure which wouldn't upset or be a surprise to anyone in the know.
There are millions of hybrids driving quite happily all over the planet with well over 59k on them.
Failures can happen to anything, doesn't mean they're all going to fail.
I suggest getting a second opinion from a specialist, as the battery definitely isn't going to cost the value of the vehicle to repair.

A replacement engine is cheaper than a replacement battery pack

Have you seen the price of a new engine recently? A new TDV6 is over £30k now.

It's doesn't need to be, as second hand parts are available.
A second hand functional battery is much cheaper than a second hand engine of similar age and mileage. It's also much easier to install a replacement battery, compared to replacing the engine.

A second hand RRS PHEV battery is under £2k to buy, an engine for the same vehicle is closer to £6k, the latter taking 10 X as much time to replace.

Yep I'll take that, but what guarantee do you get with a second hand battery?
Or do they refurbish the cells, ie take them out and test/replace bad ones?

That same guarantee as with a second hand engine, normally 30 days. Buy with a credit card and you have 100 days to claim money back should it go wrong.

In reality, a battery pack is more reliable that a mechanical box of engine components, all whizzing round at high speeds.
Yes, a battery pack can be repaired just like an engine can, it's just a big box of individual cells, and normally it's just one that goes slightly out of spec, but the BMS will generally signal the whole pack is faulty for safety.
There are a growing number of EV battery repair companies popping up, and a good one should be able to swap out a bad cell in a pack, which will make the BMS happy again.

It's not the end of the world, it's just one of those things which affects vehicles. All vehicles go wrong, especially if they're from LR. We put up with it because we love them.

I know what you mean. However, a specialist tells me he could possibly repair it (depending on the fault) but cannot get the cells for it. LR tell me they have no new batteries in stock and what's more, they don't even have a supplier for this particular battery so none are being supplied at the moment. Other people waiting for a battery have already waited 200 days. I am now exploring whether or not the hybrid function can be divorced from the diesel, leaving it as a diesel only. Needless to say, LR won't even consider that!

That will depend on whether or not it's only the electric motor drives the wheels as is the case with some hybrids. In that case, the diesel just drives a generator and it will not function without the battery.
