5.0 R-Spec: Why so rare?

[jrussell]

The Rspec is just a great car , another fellow member with a 12 Rspec that I know has over 130k all original .
It's hidden in the arm rest just plugs in and is wireless .

Hey guys I'm having so many issues with my '12 R-Spec (85k miles). Cruise isn't working, ESC, Auto Hold, ABS, TPMS lights are on all the time and the Hyundai dealer in Dublin, OH says it will be $11K to replace all the modules. I purchased for $15k 3 yrs ago and the modules are more than the car itself?? Anyone else with these issues and can you replace the modules aftermarket? Please any advise...

I live in the Los Angeles area myself. You see every car imaginable here. Like others I see tons of V6 and 4.6 models but R-spec is few and far between. Low production model, low sales etc. I can count on 1 hand how many I've seen around. I ended us sourcing my car from out of state to get what I wanted. Even in LA it's hard to find anything with a 5.0 unless it's a 2015 and up.
I love my car and I'm happy to have it and can stand out. I get nothing but love with it from people who know about them.

I have a '12 5.0 but ABS, ESC, Auto Hold and TPMS lights are on all the time. My Hyundai dealer says it will cost $11k to replace all the modules! Have you had any of these issues?

There's a possibility that the stealership told you a sales lie or whoever you talked to didn't know what they was talking about Did they run a scan tool test on your vehicle??? Scan Tool Diagnosis socket under the hood in main fuse box???

Your vehicle problem is most likely between your wiring harness connections BCM or your ECU computer It's very unusual for all modules to go wrong at the same exact time

What can I do?

They said a list of scan codes were wrong but all modules needed replaced!

Three related systems: ABS, ESC, Auto Hold and the unrelated TPMS. There is likely one failure that causes a module to not function; that module in turn being "not ready" prevents other modules from functioning. ABS and ESC strongly depend on the wheel speed sensors. If it were my car I would test the ABS and ESC by going to an empty parking lot... accelerate hard and see if you can spin the rear wheels; if so the ESC is kaput or wheel speed sensors on one of those wheels is bad. Then, while going around 30 MPH, mash the brakes. The ABS should engage, preventing wheel lockup. If any one wheel locks up, I would carefully examine the speed sensors for that wheel.

The other "common point" for these systems is the dash instrument panel itself. Unlike cars from decades ago, modern dash warning lights are triggered by CANBUS (think Internet within your car) signals from module to module; the dash display module might be kaput causing it to erroneously illuminate the warning messages. If the ABS, ESC, etc. modules are NOT generating error codes (and the dealer should be able to confirm this easily!) then I'd suspect the dash instrument panel is crying wolf. Wiring faults in the CANBUS can cause all sorts of issues too simply because a broken CANBUS wire, or one shorted out to something, blocks the communications.

Did the 4 systems fail at the same time - i.e. one day the car was fine, next day 4 things were bad? That is a statistical improbability unless a "common mode" failure occurred: CANBUS, instrument panel itself, or the +12volt power in the car went stupid... was the battery replaced or disconnected before this happened... and possibly got connected backwards? Wheel speed sensor also feed ABS and ESC at least; I don't know about Auto Hold so that is another "common mode" failure point. The TPMS issue may be separate.

What you are saying may hold some weight nevertheless if it was my car I would start with the simple things I would check all harness and cable connections first especially the one with the big clip next to the EHPS pump also speed sensor connections Next will be the Body Control Module(BCM) and next will be the ECM

 

[jrussell]

Thanks for the input Mike! The four systems didn't fail at once, it was originally the tpms (Hyundai replaced and light stayed on), then ESC, ABS, and finally Auto Hold. I'm definitely going to take her to a parking lot and try what you suggested. I replaced the battery a year or so ago before all this started but didn't do it myself, it was auto zone but they can't f that up right?

 

[jrussell]

This might sound crazy but when this first started happening, when I would fill up for gas and restart the car no lights would appear. I thought it might be a sensor in the tank or cap that would trigger the lights....

I would take your car to an Asian import repair shop and let them diagnose the issue. The issue I bet does not require multiple modules( if any) to repair.

A bad wheel sensor can trigger the ABS/ECS system error lights which can be tied to other systems. Hell, you may on have a blown fuse(or loose ground wire) that is triggering the error codes.



Note: I will not tell the repair shop that you got a expensive quote from the dealership for a major repair. Just ask them to diagnose the car with no leading information. Better yet just buy a scan tool and scan the car yourself.

Good Advice Carguy 75 because nowadays most stealerships repair service centers and some shops are parasites and extortion kings especially if you are paying from your wallet That's why it's always a good idea to have a repair manual for your vehicle as a backup to keep yourself informed,troubleshoot and diagnose most simple issues It's crucial

Yeah I don't get this. I mean it was the wheels, the badge, and maybe some interior badges and differences that made it an R-Spec in the first place (rather than a non-RSpec 5.0). The RSpec was $1000 more than the non-RSpec 5.0. If you're going to replace the wheels and de-badge, why get the RSpec in the first place? I think there might have been some minor suspension tuning differences as well, but nothing you couldn't get aftermarket.

Yes it was some things done different to the r-spec. It's the top trim, suspension, Wheels etc. So my friend there is a differences. Go and just check it out.

Why are these so rare? The only 5.0 R-Spec I've seen "in the wild" is the one that I am driving!

I have seen more Chevy SS's on the road then Genesis R-Spec Sedans. Did they just not sell as many of them because of the market?

I'm in Columbus, OH and I'm the only one that I know of. I'm having issues electrically I think. I bought with after market tires and the tpms light never goes off even after being replaced. Also recently the ABS, Auto/Hold, and the cruise control doesn't work. I took it to my local Hyundai and they told me it will take $10,000 to replace all the modules!

Yeah after what Hyundai USA did to the suspension on the Genesis BH sedan prior to 2012, I didn't in any way trust any firmer suspension adjustments that were put in place for the RSpec. And the RSpec had an MSRP $1000 more, so technically it was the top trim. But I wasn't in any way interested in the RSpec, reiterating that the RSpec wheels were an egregious design choice.
