How many other CH-R hybrid owners are suffering the same problem as I am with the 12v battery?

It is the most unreliable car I have ever bought and if left unused for more than one day the 12v battery fails and the car will not start.

The dealer has checked it several times and says that the battery is fine but the car should be used for long journeys every day.
What is the point of buying an ecological car that stands idle on the drive because it will not start.

Does anyone else think that Toyota have missold these cars and that the new technology does not match up to expectations.

If you have a hybrid, you shouldn't drive it only for short few-minute trips. Because when it's in electric mode, the 12V battery isn't charging. The petrol engine needs to run for some time to charge the 12V battery, like with classic engines.

^Vodamark nailed it^. It's electric. It doesn't charge with an extension cord, it charges with driving. Definitely not made for short trips. Made for long huals to get the best milage out of it.

Don't worry, that's absolutely false.
The 12v battery is very small and discharges and deteriorates faster than in other types of car, but absolutely nothing happens if you do not use the car daily.

It is enough to use the vehicle once a week, for example. Half an hour should be enough.
Of course, if the car is used daily it is better.

The 12v battery is charged from the HYBRID system battery circuit, it does not require the combustion engine.

I've driven everyday this week, 70 mile round trip the longest, 10 miles shortest. Car failed to start this morning for the third time in 18 months. Usual dash lights but no drive. 2020 Hybrid, Orange edition, 2 litre engine. 8000 miles.
AA called out, used their starter pack to start it and tested the big battery in boot. Meter showed 11.5 to 12.5. AA says it's a known fault.
Toyota says battery is fine at last intermediate service.
Absolutely useless reliability, it's going back, Toyota need to sort this problem out....

Hi all, Am glad I am not alone with this issue! I have a 2019 2.0 since Sept and had to call Road Assist in Oct as battery flat. AA guy said battery was fine but I needed ro drive it more often or leave it idling on drive for 60mins every few days (while we are all trying to reduce emissions). Have read many other forums - a few suggested resolutions:
  • ask Toyota to replace the standard 45aH battery with a 65aH
  • ask Toyota to change factory setting 5 days on key fob to 2-3 days. The car will keep searching for the key for 5 days otherwise which adds to draining the battery.

I called Steven Eagell today to ask if they could help. Not interested and would not change battery citing anything above 45aH could damage parts. They also said they could not amend key fob only remove all keyless access. They instead offered to SELL me a trickle charger and check battery. Really poor after sales support tbh. Worse still, really poor pre sales service as had they advised that I needed to drive it regularly, I would never have bought it!!

Given how many of us are having these issues, is there another way to raise this further and collectively?

I am now sitting here waiting for Toyota Assist to come out for the 3rd time because I have a flat battery, I last drove the car 2 days ago! I've only had the car since May 2021 and I'm sick to death of it already. It's the most unreliable car I've ever had and I'm astounded that Toyota are not doing more to solve this issue when clearly it is a huge problem for many drivers. I honestly wish I hadn't bothered and I won't be recommending it to anyone. When I complained to Toyota I was advised to purchase a tickle charger! Why the hell should I have to purchase anything?! If that is their answer, they should be providing a tickle charger to every owner of a CHR. It's now booked in at the Service Centre again, where I expect I'll be told again there is nothing wrong with the car. Absolute joke!

I’m fed up too! Bought my 1 year old CHR 3 years ago on a 19 plate. I dare not leave it more than 3 days or I get flashing lights EPB, BSM etc and clunking pumping brake pedal and all sorts clucking noises from the relay box and air con pump? I had to buy one of those jump start things from Halfords but then even that is a hit and miss scenario to get it fired up. At airports it’s a nightmare, I have to reverse into a parking bay so the AA can get access to the bonnet as I know it will have a flat battery on my return!

Pointless. Toyota need to sort this out!

I can’t believe for one moment that the alarm system and the keyless entry system drain a battery that quick?

Hiya, after I posted my rant in January, I then sent a stroppy email to Toyota, who in turn sent it to my local dealership where I bought it. To cut a long story short, as a "gesture of goodwill" they changed the battery under the warranty as they said it "scraped a pass" when they tested it. Since January I have had no problems with it, although I'm going on holiday on Wednesday for a week, so I guess I'll see when I get back whether it starts or not. Good Luck!
