Brake fail

[CeramicSilver]

I've owned a 2019 AWD GT for about a month. I've put around 2400 miles on it in every condition. Driving the family home from lunch today I approached a turn, hit the brake, and as it started slowing, suddenly the pedal went to the floor and the car wouldn't stop. Luckily I was almost home and on rural roads, so I was able to nurse it back. I had several more stops, some the brakes reacted normal, others suffered the same issue above. Shortly after the Forward Collision Assist system disabled. Honestly I've never experienced anything like this in 25 years of driving about 10 different cars. The brakes shouldn't have overheated as I was driving normally on surface roads. Anyone else experience a similar issue?

Nope, not yet. Sounds like a trip to the dealer is in order

 

[WildBill]

Sounds like a line rubbed through / burst or a fitting came loose.
I have not heard of this happening before. Hopefully just a fluke and it is an easy fix.

I've blown out brakes 3x in the past and it is very un-nerving.

 

[MerlintheMad]

Yoiks!!?? You're the first on here to report total brake failure. I'm sure @WildBill is right. Glad you didn't crash your car!

 

[M'Kehyah]

Yeah... have it towed to the dealership.

 

[NS_Stinger]

Maybe a brake master cylinder failure?

Agreed, total brake failure years ago was diagnosed as a master cylinder fail. I had the same symptoms.

I've had a master cylinder fail once, years ago. Don't recall which vehicle. But I do recall discovering it while driving, and pumping the brakes like mad: pumping seemed to create some pressure so that the brakes actually stopped the vehicle. Then, sitting, the brake would just steadily go clear to the floor. Iirc, I reached down and pulled the pedal up and worked it by hand until the system had enough pressure in it to allow me to work the pedal with my foot, pumping away. This condition lasted only as long as it took to get to a convenient place from which to get towed to the mechanics shop. I had no idea at the time what was going on; so, I got educated about "master cylinder" stuff. I always gently press and release my brakes anyway, so de facto I am always testing to make sure the pedal isn't going "soft" on me.

I wasn't as lucky I clipped a flat top truck to survive i swerved and rebounded onto someone's lawn. The cat was wrecked, I was unscathed.

OMG, lucky you didn't take out a garden gnome as well.

The car was opened up behind my head like a tin opener, it was only my reflexes that saved my life.

Lol. Until you brought it my attention, I saw "car" when I read it.

My Stinger's 2.0 4.cylinder brakes failed recently when I was pulling into a stall going less than 5mph. Luckily the curb stopped me. I'm leading the car and KIA will not let me break the lease even though I feel the car is t safe to drive and they say nothing is wrong with it and can't duplicate the brake failure. What was the outcome of your situation?

 

[MerlintheMad]

The strangest thread on the forum! Two, count 'em TWO, single post brake failures. Are we going to at least hear back from you?

I'm pretty sure you meant to type "LEAVING", not leading? So, you've left the car with Kia. They can't duplicate. You won't drive it. The lease remains in force. The only answer if you are determined to get out from under this is legal action. Keep Kia on the hook. Let them know each step in your pursuit of legal action. It will take I don't know how long. But a car with failed brakes is a prime candidate for full lemon law redress. You'll be out of the lease and will get your money back for any made payments; I think that's how it works out. Someone else can confirm or clarify.

Kia won't let me break my lease without incurring their penalties and they refuse to give me another Stinger with the same monthly payments. Instead, they are offering me to trade out of it and buy an Optima with higher monthly payments than my Stinger lease. Other option is for me to just take the Stunger back and it will have to have the breaks fail two more times in order for it to qualify under the lemon law (requires three separate instances of the same mechanical problem). Who in their right mind wants to take back a car for it to have brakes fail 2 more times before will Kia do the right thing?? Wouldnt they not want to take chances and switch out my car or break my lease, rather than have a driver get hurt or hurt other people because of faulty brakes? Kia would rather play the odds, instead of playing it smart and cheaper to either break my lease, switch me out to a new Stinger with same payments instead of them facing a multimillion dollar lawsuit in the event breaks fail again and people end up getting hurt.

 

[MerlintheMad]

I'm not believing this. BRAKES are the difference between life and death. Something in communication has broken down. Keep on this! Talk to Corporate. Forget the dealer.

It’s s**t like this that makes my blood boil against Hyundai/Kia. Want to improve your rep guys? Don’t tell a customer that you don’t care if they get killed or not!!!

 

[SteveCo]

Not making any judgements here, but if Kia can't reproduce the problem and can't find evidence of anything mechanically wrong, they probably have concluded the issue was actually due to operator error (realized or not), or even an attempt to break the lease - rather than a one-time self-resolving brake system failure.

I'm sure they would have looked over the braking system in minute detail, and would have at a minimum replaced any components even the least bit suspect (which it doesn't sound like they did). They certainly wouldn't be turning a car back over to the owner, untouched, if they believed there was any chance of brake failure occurring.

brake failure nearly always traces back to three items—metal lines, the master cylinder, or the booster

interesting read regardless. and the comments.
