2013 Hyundai Genesis R-Spec Sedan EPB and Auto Hold

[Woody6977]

How many miles on your 2014? Sounds like a nightmare.

Actually mine is a 2013 R-Spec. I have 78,800 miles. It's 10 1/2 years old.

Gotcha. So were your brakes really that bad? Pads, rotors and calipers? Possibly an electrical glitch?

My brake pads were not bad at all. All the pads were at a level 4 so I have 2000 to 5000 miles left on them. The rotors were in great shape.

Question.... Is your 2014 an R-Spec? Do you have the full electronic brake package?

No thank the Lord. When I purchased my car there were two exact cars sitting side by side. The one I chose didn't have the sunroof and the "big" screen in the dash. Didn't want the sunroof because I didn't use the one in the 2006 V6 Sonata I owned previously and I don't need the navigation system. I guess it had all of the "bells and whistles" and wasn't worth the extra $8,000 to me. I'm still on the original brakes at 214,500 miles. Had a service today and the technician told me they were getting close. I will be ordering them soon.

7 1/2 weeks later, $2,710 in repairs, and I now have my car back. The sad part is Bachman Hyundai refused to acknowledge and mistakes on there part, they still charged me over $1500 in labor, and I still have to take the car into my local shop to have rear brake pads installed, the tires rotated, balanced, and an alignment. That's another $300 dollars.

I would boycott that dealership. Glad you have your car back.

What ended up being the issue? I'm in the same boat. Replaced the brake pads, rotors, master brake cylinder, fluid flush. Car drove fine for 1 day, then the brakes started locking up and had to get the car towed. Brake mechanic said it's a bad HECU (2014 Genesis R-Spec 115k miles). But I'm not so sure. Seems to be more wiring related. Car will sometimes work fine until I plug/unplug a scan tool, then it acts up again and scan tool has intermittent read issues.

Bad brake fluid.... Before you replace anything. Have the fluid flushed completely and replaced. If you need parts go through eBay or find a good company that will rebuild like ECU Testing. Dealer wanted $595 for the brake master cylinder, eBay Hyundai OEM $75. ABS hydraulic control module, dealer wants $3499. ECU testing will rebuild your original OEM part for $390. Lifetime warranty.

I've had my brake fluid flushed twice and bled three times in the past 4 months trying to diagnose this issue. Car never had the fluid changed prior (about 112k miles).

I bought a remanufactured HECU unit from eBay from 'i am motors' for about $300, but they sent me the wrong part. :-( Waiting for a resolution there.

Yes ECU Testing is out of Great Britain but in the end it's worth it. Did you have your original HECU pulled?

1. Fill out everything on there form.
2. They will email you a DHL shipping label. Took 4 days to get from Indian to GB.
3. The sucky part is it took 7 days before they even looked at my unit.
4. Ones they looked at it they called me with options.
5. Took another week to rebuild and 2 days to ship back to me.

My unit tested good. But I had them rebuild it anyway so I would get the lifetime warranty. $390

I wanted to update this continues nightmare and hope that everyone that reads this can keep it form happening to them.

3 weeks ago I drove to my father-in-laws condo and as I was parking the car completely died. No power at all. I was lucky to coast into a parking spot. I had AAA come and they were going to give me a jump and found the over voltage protection for the batter had engaged. He pulled the 50 amp fuse and it reset after putting it back. He tested the battery, 13.1 volts without the car running. I fired up the car, he tested the voltage at the fuse panel and quickly shut the car off. He was getting 15.5 to 16.1 volts under load. The Alternator and battery was replaced September 2023. During all these issue I told Big-O who installed the Alternator, I thought the Alternator was defective. They argued 3 or 4 times saying it was good it had to be something else electrical. In the end I had the car towed and forced the issue on replacing it. They begrudgingly complied. The car has run for the last 3 weeks with No issues. Go Figure...

Glad to hear you have the issue resolved.

Agreed, my mistake was having car towed to Bachman Hyundai. It should be illegal to charge what they charge for parts.

ABS hydraulic control module:
Dealer = $3499
Hyundai Direct = $1350
Rebuilt = $250

Brake Master Cylinder:
Dealer = $895
Hyundai Direct = $350
New OEM = $75

I am at a loss here as well as my 2012 Tech package had almost no brakes while my wife was driving (no other codes, lights). She was able to bring the car back and I took it to a local mechanic as I saw brake fluid on the driverside rear, he replaced the line. While testing the car, it felt fine and I pressed the Parking brake to test and it threw all kinds of sounds from under the car and the epb light came on and the parking brakes were locked.......

Not sure if there needed to be some reset after the above brake line job.....now I had no choice after 4 weeks to get the mechanic to unplug the epb as he is not able to do much more.....
