Sporadic Low Brake Pedal Issue

[GenTex]

So you are saying that you just changed the ABS Brake Module and it only last 6,000 miles and then failed again????? God D*mnit...this pisses me off.

So what did they put in there for the 2nd ABS replacement? What makes you feel secure that this won't happen again in another 6K miles?

Thanks!

I apologize for being so long in the tooth with my previous post, and I was probably somewhat confusing with the chain of events, but no, there wasn't a 2nd ABS involved. When this issue first happened, the brakes went to the floor when my wife pulled into a store parking lot. When she came back out and started the car, the brake pedal was back to normal. About two weeks later, it happened again while she was going to work. I met her at her work at the end of the day and I drove the car to the dealer, while she followed in my car. The brake pedal was still going to the floor when I pulled into the dealer. Apparently, the next day when the mechanic started the car to pull it into a bay, the pedal was back to normal operation. They kept it for a week and could not get the failure to replicate. When I picked the car up, the pedal was perfectly normal, as if there never was a problem. The normal pedal lasted for another 6k miles, before it happened again going to the floor. This time, normal pedal did not return, so they were able to identify the problem as a faulty ABS hydraulic module. Seems the fluid was bypassing internally in the module, hence the low pedal. The part number for the module they replaced was 58920-3M0A5 Hydraulic Module Assembly. Cost with part, labor and tax was $2310.06. Hope this clears things up. If anyone wants to know my dealer's name and #so their dealer can contact them about this "secret" problem, just let me know, I'll be happy to provide.

I am very happy to find this forum because I just had a recent incident with my brake pedal going to the floor and the car not stopping. I was a proud owner of a 2009 Hyundai Genesis with approx. 61k miles. Now I’m very nervous and terrified to drive this car as I have no confidence in its mechanical soundness or reliability to stop.

Last week I was driving my car thank God just around town and not on the highway like I am usually or with my children in the car, on a very sunny day with no wet roads as I approached a red light with cars stopped at the light in both lanes, I pressed down on the brakes and to my surprise the brake pedal hit the floor. I was going about 30 mph I was in panic mode as I started pumping the brakes and nothing. I started slowing down only because I was so far behind the other cars when I had taken my foot off the gas pedal. Well I stopped unfortunately only because the car in front of me stopped me.

There was not much damage to my car and the car was drivable. I had it towed because I was afraid to drive it to the dealership, where they could check it out and fix the problem, you would think. That was 4:30 PM on Friday the service agent said they would not be able to check it till the AM. On Saturday at 8:55AM the dealerships got back to me and guess what they couldn’t duplicate the problem, so the service agent told me he had drained the brakes and bled the lines and changed the brake fluid to DOT 4 and the car was ready to pick up. I told him he was going to have to speak to my husband because I felt he was being very condescending and short with me. My husband spoke with him and he agreed he wouldn’t want his wife driving the car either, so his recommendation was to leave the car and have the manager drive the car for the remainder of the weekend to see if he could duplicate the problem. Well on Monday afternoon we got a call and were told to come pick the car up as they could not duplicate the problem and couldn’t replace any parts without duplicating the malfunction. We now have the car back in our possession. With reading all the different threads from this forum we truly are dissatisfied with how Coconut Creek Hyundai has handled our situation and worse yet we have a car we feel is unsafe to be driving.

Time to call Hyundai customer service and report the brake issue and the dealer response.

The ABS module can have intermittent issues. I had mine replaced after a near miss. Tech could not detect the problem in the shop with car at a standstill, but when the tech drove the car, he felt the soft pedal.

Have a lawyer write a letter to the dealer.

Report the accident to NIHTSA: https://www-odi.nhtsa.dot.gov/ivoq/

I wouldn't place the blame on the dealer. They have been instructed by Hyundai Motor America (who pays the dealer for the warranty work) to not replace any parts unless they can duplicate the problem, even if it is a known problem with the car. So while I agree that it is shameful that they will not replace the ABS unit, it is the fault of HMA and not the dealer.

Writting to Hyundai Customer service has been a futile exercise for me. Lots of documentation and face to face meetings offer, I think, a better path to correcting any issues. Using a lawyer means expense and time but that might offer the highest efficacy yet.

When my 09 Genesis (63K) brake pedal went to the floor two weeks ago, for the second time, I knew I had a problem. I quickly researched on the web and found this -thank God. Everything that owners have written about, prepared me for my conversation with the service adviser. I brought the car in on Monday (5 days ago) and waited for 2 hours. I was told the mechanic WAS able to replicate the problem. I was shocked. I knew this was going to be a fight but the mechanic found the problem. The dealer kept the car and waited for the extended warranty inspector to visit. They would start the repairs immediately after approval from inspector. 2 days later, the inspector was NOT able to replicate the problem. A series of phone calls occurred and I will be picking up my car later today. I will have a new module and lots of piece of mind.
I think this forum should be updated. The title should read "2009 Genesis brake problems." This is a serious issue and it needs exposure.

Well I had another incident with my 2009 Hyundai Genesis’ braking system, again.

I had to pick up one of our daughters from work Saturday night. As I was driving, I stepped on the brake pedal to slow down to enter the parking lot, and the brake pedal hit the floor and the vehicle would not stop. Since it was midnight, there was not a lot of traffic, which allowed me the time to step on the brake pedal repeatedly until the brake pedal engaged.

The first time this occurred I got into an accident and rear ended someone. Luckily, I was traveling at a low rate of speed and no one was seriously injured. In the end, I still got a ticket, my bumper is cosmetically damaged, and someone is going to put in a claim against my insurance company.

I called my dealership Sunday morning and they had it towed in, again. Now I have to wait and see what they find. Last time they couldn’t duplicate the problem and returned the vehicle to us the same way it went in. In addition, they said Hyundai USA’s policy is to not replace anything unless they can duplicate the problem. We also have the extended warranty and that was of no use.

Hyundai USA contacted me because of a comment I left on their Facebook account. Hyundai USA said they did an inquiry with my dealership after the first incident and insured me the car was safe to drive. Hyundai USA said they would be putting in for their own “investigation” and that it would take 6-8 weeks. They said they would mail us paperwork to fill out which they did via Fedex. Now I have to wait to get the car back since it’s at the dealership, again.

In the meantime, I have to drive a vehicle which is clearly not safe. I cannot understand why it is Hyundai USA has to do their own investigation. Is the dealership not competent? Do they know something the dealership does not? How can it possibly take 6-8 to weeks? Are there that many mechanical issues and complaints being investigated all at once? Shouldn’t a braking, or stopping, issue be addressed at the top of the complaint list?

I’m beyond just being nervous about driving this car. My husband and I’ve been taking turns with the car; whoever has the kids drives the truck. As luck would have it, he was out of town with our son this weekend, so I had the car.

I don’t feel like someone needs to be injured or killed in order to get someone to repair the car. Something needs to be done. I am to the point that I would rather drive another vehicle all together, even if it’s from another manufacturer. After reading multiple comments on-line about the 2009 Genesis’ braking problems, I would have purchased another model or year.

Very dissatisfied with Hyundai,

I would contact a lawyer. You should mention to the lawyer that there is a strong possibility of a class action suit, or at least representing multiple owners.

 

[Locomotion]

We only need one lawyer who has the funds and drive to start this process. As I have said in an earlier post it is not only us forum posters who have experienced this problem but other Genesis drivers who have had the problem fixed (or not) and did not get on this website to report this issue.

The brake fluid is not the problem. The ABS Brake Module is the problem. If someone could somehow have all of the dealers pull reports of all the other owners who have brought their cars in for total brake failure I think we would all be sitting here with our jaws on the floor. I truly hope this happens and all of these cars are recalled as they should be, and that the ABS Brake Modules that they are replacing our cars with do not fail us yet again.

Again, I worry about of you, and myself, more than you know.

Add me to the list on the sporadic braking issue. A few months ago, as I was pulling into my garage, the brakes were suddenly gone. I pumped them a few times to wake them up, which saved me from going through the garage. Next day, no problems on the commute to work. A few days later, on the road, same deal - brakes almost to the floor and almost nonexistent. Pumping them a few times helped but this is B.S.

Took the car to the dealer for oil change, etc. and asked them to inspect the brakes. "Everything checks out." After reading this thread, I just called the dealership and set up an appointment for tomorrow morning, and I told the service advisor that I will not be accepting, "Everything checks out" as an answer again. I told him about the ABS Module and, as I'm typing this, it seems to make sense - seems to me like the soft brake pedal appears randomly, but now that I think about it, it seems like bumpy or unstable road (like pulling into my driveway, which has a steep "bump" at the bottom of it) triggers the soft brake pedal at least some of the time.

I'll be interested in seeing how responsive the service advisor is if he can't replicate the defect...but I'd rather he just replicate it and get the ABS Module replaced.

Thanks to all who posted - I endorse and echo the notion that we should all be vocal about this because the brakes working on a car is as important as engines working on a jet.

Add me to the list! 09 Genny in Texas with 62,000 miles, 2nd owner, dealer "no. We are not aware of any problems with Genesis ABS Module/brake problems".

I just had a similar incident with my 2013 Genesis Coupe 3.8L

I was stopped at a red light in the left turn lane. All of a sudden I was rolling forward while my food was firm on the brake. I was able to press the brake even further, but I kept rolling forward until I crashed into the car in front of me. Thankfully, it was a very sturdy truck with a trailer hitch. I have damage to my grill where the hitch hit my car. The brake pressed to the floor and did not stop my car from rolling forward. I was able to drive the car to the closest parking lot in that intersection. I waited for a tow to the dealership. The brakes seemed to work fine again; the service department told me there was nothing wrong with my car or its brakes. I left the car with the mechanic to drive home and continue to test it to reinact the problem. When I googled "hyundai genesis brake failure", there were a few other instances of this issue. I am so scared to drive my car again.

 

[Southern Boy]

When I had the brake fluid changed out on my Genesis I asked my Technician if the TB Hyundai issued was due to the reported brake failure / fading reported.

He said no that Hyundai just decided that DOT 4 synthetic was the correct brake fluid for these vehicles.

He went on to explain that the intermittent failures and fading brake problems was traced back to the ABS units. It seems that some of these ABS units had air bubbles internally and no matter how many times they were bled all of the air bubbles couldn’t be removed, so the policy was just to replace them when there was complaints of intermittent brake failure / fading.

This could be the problem. I have posted this on another thread on this site detailing these braking problems, but what my technician told me about the ABS unit problem was the first time I heard this explanation

 

[Locomotion]

People will have to die, and more than a few, before Hyundai will recall the ABS brake modules as the cost of lawsuits will have to outweigh the cost of a massive recall. It's a numbers game.

Report your incidents to Gunkk's repeatedly posted link and help save a life. Otherwise you aren't part of the problem or the solution, you are just part of the landscape; and venting gets us nowhere closer to the truth.

 

[Jean]

I reported my ABS module failure to the NIHTSA back in April when it happened. Hopefully other Genesis owners are doing the same thing. I am irritated that everytime I drive this car, especially at higher speeds, I am uncomfortable. I want to go back to be relaxed when I am driving.

 

[Geneva]

This is the correct diagnosis I spoke with the Service Manager at Orlando Hyundai, I have an 2010, 4.6l with 90k miles and my car currently does the same and before it was intermittent but know its constant , and the brakes work it just doesn't catch until the pedal is low to the floor, Usually a master cylinder will require constant pumping of the brakes. This issue is just the available brake isn't there until the pedal is really low. Rumor has it they have a issue with the ABS unit NOT resetting itself after an abrupt or emergency stop and they then cause the low brake issue. I'm supposed to get mine in around next week for extended warranty to fix mine.

 

[gthmcty1]

Well.......add me to the list as well wifey called me in a panic saying the car won't stop unless she puts her foot through the floor....09 Genny with 71000 on the clock, can't wait to see what the "stealership" is going to tell me since the car is out of warranty....

 

[gthmcty1]

I took the vehicle over to the dealership and just received the called on their assessment what they would like to do is replace the master cylinder and the BCM (body control module), but they need to call out an adjuster to review it and get it approved for the repair. Will keep you all posted on the outcome!.
