What to look for in used bk1?

I’m planning to purchase a bk1 within the next 2-3 weeks (preferably 2.0t but I’ll take what I can). Just wondering if there’s anything specific I should look out for, current car I’m planning to go look at is a 2012 2.0T A/T with 89k miles for $7900. Car looks clean inside and out and has a clean Carfax with 2 previous owners. Just really want to know about the reliability of these cars as I’ll be driving it year round

Stay away from the 5 sp auto. And look in the trunk for water. If you see any then pull the side foam insets in the trunk to look down into the wheel well.

Exactly what Red said - i have 2010 2.0 A/T and gearbox is what kills this car, go for manual or get ready for swap to manual. Relay 5at is just annoying and takes out a lot of fun from this car.

If you want AT go for ZF (bk1 3.8 or BK 2 2.0 / 3.8)

the bk2 isn't actually a ZF trans, it's hyundai's knock off

Can you possibly elaborate more? I would love a bk2 but it’s slightly out of my price range and I’m finding mostly 2.0s in my area.

Well in *my opinnion* the 'feel' that this A/T gives off is just bad
Form my perspective these are the cones of this transmission:

- Robs a LOT of power car just feels slow with it
- Completely no way to steer with the gas pedal in corner, torque converter soak ups gas inputs so its hard to i.e correct a slide
- Very 'laggy' reaction to gas pedal inputs - takes a lot of time between pushing the gas - engine reeving and the torque actually appearing on wheels
Manuals are unbeatable in this regard
- Paddle shifers have a software bug when you can make it double down shift from 3rd to 1st (annoying)
- The shifting it self is fast BUT the transmission doesn't always react to your action (I.e. 3> 4> 5 gear paddle shifters)


So from my perspective it all depends what type of driver are you
- If you don't care about 'feel' that much then the only real downside is the power robbing and bad efficiency (gas mileage) this AT has
- if you really 'feel' the car, then this is relay a step in wrong direction (and i admit i did make a mistake with getting this AT i will probably swap it)

ZF copies that AKGC mentioned are probably tones of better (cant compare this is my first automatic), but some of above issues are inherit to torqe converter setups so.. they will also have them (maybe less pronounced)

Only real benefit that i see is quick of the line 'up shift' performance in Auto mode (if you ignore the parasitic losses that is) in traffic i usually accelerate faster than other cars not due to power but due to fact 80% of cars in my place are manual so they loose time on granny shifting when in stop and go city traffic

At least it's not a CVT.

the BK1 ZF trans have had issues of their own.

Both auto transmissions, feel and shifting, are due to the TCU programming.

The auto 5 speed is the only transmission that hasn't really had issues.... aside from the power loss through it.

Supposedly the 5 speed is a hyundai knock off of the Nissan Titan RWD transmission.

Partially true but no amount of software will cut out the torque converter behavior, i think i relay need an automated manual with paddle sifters instead of torque converter A/T

That's not how a torque converter works. It uses hydrostatic stall of the stater to couple it with the torque converter casing. The don't (well not suppose to) touch.
the cranks spinning the torque converter casing is what causes the transmission pump to work.
ALL the shifting is done by the TCU by controlling solenoids.

That's what I meant by shifting feel. It's not the feel itself, it the lag between telling it to up a gear, in dummy shift mode, to when it actually does it.

It's more reliable than a manual, and a better way of transferring torque with less user error, that is why top fuel drag cars, tend to lean towards using torque converter transmissions. (not all torque converter transmissions, are automatics)

So would you say the 5 spd shouldn’t be too bad if power isn’t my concern (main concern is reliability)? In terms of reliability would you recommend the auto bk1 2.0 or the 3.8 for a first car? Also I read the 2.0s have issues with the timing chain stretching, just wondering if that’s common too.

chain stretch is going to be a thing on any chain driven valvetrain engine, regardless of make even on the 3.8. It's better than have a timing belt suddenly snap.

First thing I would do is have the chain replaced so it's one less thing to worry about until the next 50k miles.

The bk1 2.0 auto will feel down on power, compared to it's weight and torque will be lacking until it hits like about 3k rpm. (torque) for me this is fine, because it helps with driving in winter (too much torque breaks traction)

For someone's first car, I would shy away from a genesis. You will be surprised at how ridiculous stores/people are charging for aftermarket parts, compared to other more popular cars.
