Re: brakes failed

Mon Aug 22, 2016 8:59 pm

Update: I took my car back to the Kia dealership and they sent out a technician from Kia Canada. They did not find anything wrong with the car and have deemed this to be a driver error. Obviously I do not feel safe driving this car anymore. I live in a very hilly area and having the brakes fail at any point could be fatal.

As I had leased the car, the only option I have been provided with is to buy-out the lease and sell it back to the dealership at a "used and damaged" price. By the time the dust settles, the cost to me will be over $12 000 and in the end I have NO CAR and responsible for higher insurance premiums (ICBC also deems this to be default driver error unless proven otherwise). This car is <24 hours off the lot, ~200 km on the odometer (had 120 before I drove it) and is deemed 100% safe by Kia.

I am beyond frustrated and will be writing letters to Kia Canada. Any suggestions? For those that have had similar concerns, if you are willing to have your name put into a letter, please let me know.

change the pneumatic/hydraulic assistance from the pedale brake command.

this problem has been report on many Leaf (very high difference between the regeneration braking and the mecanical brake level of the pedal).

Otther tip before you drive :
1) activate your car (ON)
2) pump on the brake pedal (5 times)
3) drive
4) ALWAYS use the electric brake parking (auto-disabled when you move from P to D or B).

do the same everytime you take the car (or when you activate the ON/OFF switch).

hey guys. im new to the forum. i dont own a soul ev YET but im hoping to pull the trigger on a 2017.

im pretty concerned about this brake failure issue. i live in hamilton ontario and as anyone whos been here knows we have an escarpment that splits the city. i have to travel up and down this escarpment daily for work. having a brake failure like im reading about is a major concern.

i recently test drove a 2016 luxury for an hour or so. it seemed to drive great and the brakes gave me no issue. it had 125 km on the clock. i did find it very odd how the brakes engaged tho. almost a disconnected feeling and i guess i know why.
ill be looking forward to any updates on this issues.

We don't really know much about this error yet. 99.99% of drivers have not had this problem.
In the few cases where it has occurred Kia could find nothing wrong.
It is the most serious flaw currently mentioned, so worth keeping track of to see what is causing this issue, but not something that would cause me to worry when going out in the car. Here in Jeju it is bad drivers that cause most of the accidents not bad cars.

I've been thinking about the 'brake failure' issue for a while. Something occurred to me: there is a difference between an EV and an ICE when it comes to pedal misapplication. In an ICE, if you're in Neutral and you press the accelerator when you mean to press the brake, the pedal goes to the floor and there's a loud roaring noise. In an EV the pedal goes to the floor and nothing happens and then you panic.

For me the moral of the story is never use Neutral. If you're waiting in a queue, use D or B. The computer knows you've got your foot on the brake so it's not straining the motor or anything. And if you're actually stopped, use P (and maybe apply the EPB).

I forgot to post here, but my dealer replaced my iBAU due to excessive clunking/banging noises. The new unit is silent in the regen/friction transition and while creeping at low speeds. These were the conditions which made the most noise before.

no banging noise but definitely some clunking noise when braking since day 1, another SoulEV owner told me she heard the same noise, took it to dealer once but the guy pretended he didn't know what i was talking about.

This is what they told me at first as well. When the dealer's master mechanic drove it he immediately identified the noise as a defective iBAU and replaced it. Dead silent now.

Would be easier if they hadn't added that acceleration when you lift off the brake. Would make putting the car into Neutral irrelevant.

... use the Electric Brake Parking ... in B.
easy.

i use many of time (on flat or downhill ... yes, downhill !) when i'm to lazy to push a long time, the pedal brake (on A STOP, not when i drive !).

Electric Brake Parking is automaticly disengage when you push the throttle.
