2009-2011 Genesis 4.6 V8

Does the steering arm come from the top, such in a Chrysler LHS?

The control arm I'm touching in the picture belongs on the driver side of the car. I installed it wrong, dad snapped the picture, and then realized my mistake. The bow it has would interfere with the wheel on passenger side, but clears the wheel on driver side. The correct one is a mirrored shape of it, therefore clears the wheel. But does also come from the top into the steering knuckle.

Yes it looks like the damage to the Genesis might not be too bad. Hope its ok

On the bright side - Genesis only has one thumbnail sized dent from the tree fall. Plus a couple very light scratches that will literally buff out in couple minutes. Thanks to the garage for taking the hit.

The ECU had a blown capacitor inside. Found a new capacitor online, re-soldered, but unfortunately that didn't bring the ECU back to life. Used ECUs are cheap, but can't be reprogrammed, per Hyundai. Now going to have to shell out $3k for new OEM ECU and its replacement & programming at the Hyundai Stealership.

I would double check on the reprogamming before shelling out that much money. That is a depressing amount. I am in suspect of that info.

Update.. I see after a quick search that the VIN can only be programmed to new (virgin) ECU. Maybe check to see if your current can be rebuilt and retain VIN etc. Ughhh

Called multiple dealers and Indy shops, and all say the same. OEM ECU is ~$1800. There are some unlocked ones available from aftermarket for $1300, but no guarantee that a dealer will accept it and do the work. Most dealers reserve the right to deny the work, unless parts come from their suppliers. And the rest of cash is diagnostics fee, replacement labor, and reprogramming with Hyundai GDS factory scan tool. Very depressing. So depressing that I even found a bunch of cars under $3k, but sister (the owner of that Genesis) wants to fix it and keep driving it.

What about a used one @Graham Piccinini ? If you match the ID on the ECU with yours, would it not work without programming? I'm guessing not. The other option, as @Drifter mentioned, find someone who rebuilds or repairs on them. Outfits that do instrument cluster repairs, comes to mind. Good luck!

How many miles on this thing now?

Around 125k.

After keeping it hostage for a few weeks Hyundai notified us that a new (virgin) ECU is not available anywhere on the planet, and no estimate on if it will ever be available again. Nice.

Found a company in Florida that has refurbished ECUs and can try to clone the damaged one onto a refurbished one. All in that should run $2k, with a 50/50 shot of this cloning working successfully... Judging by their reviews - they have done quite a few of these 4.6L Genesis.
The 3.8L and 5.0L must have a different and more reliable ECUs...

ECU dilemma came to an end, for now.

After more searching found a local ECU specialist. He tried to clone the original ECU onto a used one I bought on eBay. Unfortunately that didn't work, as original ECU was too far gone.

Thankfully he volunteered to come and try in person. After a few hours of his magic the mighty korean TAU 4.6L V8 roared to life for the first time since September 27.

Overall repair cost is under $700, including another used eBay ECU. (Plus $600 between dealership diagnostics and towing to/from the useless dealership.) Not sure how long the Genesis will stay in the family now, its days with us may be numbered. Just in case, before anything else "bricks" it for a few months...

Yesterday started it up and took it for a first ride since the ECU fix. Found out that ECU wasn't as fixed as I thought it was. The Genesis ran, but misfired on cylinder 3 (despite fresh plugs and new NGK coils on all 8 cylinders) and brake pedal switch gave up the ghost, leaving the brake lights on all the time...

This is when my sister pulled out a letter from a local KIA dealership with a nice offer for the Genesis, if she buys a car from them. And so we limped the Genesis to that dealership, and a few hours later left with a 2025 KIA K4, with 19 miles on the ODO and all the factory warranties. The Dealership also gave a LIFETIME ENGINE WARRANTY, if she does at least 1 oil change per year at that particular dealership.

I'm still nervous, because KIA. But so far it's quite nice, the K4 is A LOT more spacious than their Forte was. Leg room wise it's nearly as spacious as the Genesis that we left at that dealership. And ride quality is a lot smoother than the Genesis was. The 2.0L MPI does give me some hope for long engine life... And if it goes - the 100k factory warranty or the Lifetime Engine dealership warranty should cover it. The CVT is doing CVT things while pretending to be an automatic.

We're just happy to close this stressful chapter of a nice driving V8 Genesis, that unfortunately left my sister stranded many times over the length of ownership. The K4 is slower, but hopefully more reliable...
