Battery OEM Mazda or OEM KIA
Even though the battery tested fine the problem went when I replaced the battery.
Pros: problem went away
Vehicle:
Kia Ceed
Also, most car manufacturers know that customers are generally bad at doing the "correct" thing, so they protect their batteries by design.
When you are charging to 100% you are actually closer to 95-97%, when you run your car to 0% it's actually 5-7%
All because it's easier to show you another number and build the protection into the system, than to change people's habits.
Pros: batteries protected by design
Vehicle:
Kia
My Kia EV6 does 10-80 in 18 minutes which is getting close, IMO. It\u2019s certainly enough for me
Pros: getting close, enough
Vehicle:
Kia
My 2019 e Niro has done 67k miles and range has not dropped significantly. Over 300 miles suburban in summer and around 230 motorway miles with heating in the winter.
Pros: good range, roomy
Cons: not exciting, looks like potato
Vehicle:
Kia
Mileage: 107826 km
Of course you do. 16-19 kWh/100km to 20-23 kWh/100km. Kia EV6.
Pros: increased energy consumption
Vehicle:
Kia
My battery conked out at the normal time after 6 years. But it still didn’t give me any warning that it was dying. 2019 Mazda 3 here
Pros: lasted 6 years
Cons: no warning before dying
Vehicle:
Mazda 3
I bought a ‘24 GT with 5k miles and regret it every day. The battery had to be replaced at 9k miles and we had a loaner for a 5 weeks. Everyday issues like Carplay not working 50% of the time and the backup sensors being way too sensitive drive me insane.
Cons: battery replaced, carplay issues
Vehicle:
Kia
Mileage: 5000 km
My brother and I both have/had 6 speed 2015 Mazda3 (me the hatchback, him the sedan), and both of us had terrible issues with the Mazda brand batteries.
Cons: terrible issues
Vehicle:
Mazda
These are excellent cars but for some reason the batteries they use are bad. I had a 21 Mazda 3. The battery failed in 2023. They replaced it under warranty. The new battery lasted literally less than 6 months.
Cons: poor quality, short lifespan
Vehicle:
Mazda 3
Mazda OEM batteries are trash. Always have been. 35 years with Mazda and we stocked a ton of them.
Cons: poor quality, unreliable
