Wahai /k,

Ayam went through some Hyundai Kia club MY FB, quite a few issues related to ECU.
Symptoms like stuck 3rd gear, xmas lights, etc...

Any owners here can share the experience of these cars ownership?

Is it a common problem?

How frequent do you need to replace the ECU?


TQIA for the feedback appreciate it.

Just changed my ecu for 1.6k Kia cerato 2013

Yes this is prevalent in our Kia group

kia forte 2012 - till now, no issue!

Thanks.
After how long of your ownership this issue occurs?
What are the symptoms did you observe?
How much is the cost of repair / replacement the ECU?

Really?
Depends on luck?
Or there is a preventive maintenance can be done to prolong the ECU?

only 1.6 ... before FL .... due to some capacitor leaking which easy fix and in FB group they have someone can do it fast and few hundreds... u wanna problem free.... get 2.0...

yes.

i guess we all need luck in most car purchase, any brand.

nothing u can do, its electronics and all have lifespan.

imagine modern hyundai kia models require so much electronics.. gg la

FL version ok?

so far mostly b4 FL....

My previous previous Hyundai Elantra no issue with ECU

kia carnival 7 seaters 2023, so far so good.

last time forte 2010, limp mode.
end up change car.

u sure kia , not alfa romeo ah?

Its the only major problem affecting Kia Cerato 1.6 pre-FL and it is relatively cheap to fix either before or after the problem comes up. Other than the ECU issue, the car is rock solid reliable and cheap to maintain. Mine is from 2014 and has done 220k km now. Had the ECU problem about 4 years ago and got it fixed for around RM800. If you fix it before it goes wrong, its around RM600+ I believe.

Picanto 2014 here. just replaced ECU last year. so far so good

symptom - cannot start. battery/alternator/fuel pump all ok

Rio 2013 & Sorento 2014 until now no ECU issue yet.

Thanks.
Just replaced once?
Yours is manual or auto?
How is the FC?

why not get repaired by Pakia ? , maybe only half the cost je

My previous Hyundai Elantra MD year 2012 replaced it's ECU 2 years ago, reason being the battery voltage is lower than required and it spoilt the ECU.

voscar

ECU, just 1 leaky capacitor
Brake switch sensor

Just once in 10 years
Manual
FC very good. no regret buying

Crankshaft Position Sensor

Cerato 2015 best buy nowadays

below 20k and much solid drive compared Japs

BBB

for k3, 2017 and below got ecu issue.

facelift 2018 onward no more such issue, for now.

I'm based in kuching bro. When I needed him he couldn't come down

ecu problem (and even more engine related problems) more common on 2.0 nu/2.0-2.4 theta engine that appeared on newer tucson/sportage/k5/sonata (many reports in north america)

Here is someone who tells the truth but then when I advice customers not to do so, I can see these words flying across their forehead, ko ni nak scam aku ke ? 🤣🤣🤣🤣🤣 Well I have to find the next person who listens.

I don't even know the voltage of my new battery, the mechanic just says it's time to change during service then quote me a price and I just say ok.

Lesson to be learnt is to remember the voltage of your battery and don't let mechanic suka suka change it.

battery voltage is lower than required

wat could have caused this issue ?

Kia k3 1.6 issue is due to capacitor leaking which the fix is change the capacitor only... I don't think lower voltage will cause capacitor leaking???

Here....2.0 Nu mpi no issue....issue mostly 1.6 pre FL...

Yup you are correct.

Talking about suka suka change, actually this practice is extremely rampant in the industry especially when it comes to the faulty Starter Motor. The inability to accurately diagnose this and resolve this issue, will costs the customer. Barang rosak tak ditukar tetapi asyik tukar barang yang tak rosak. Memang hebat. Cari makan bos.

Hyundai matrix 1.6 mileage now 296k. Ecu still ok. Only changed the transmission control module last year

Kejap ada current , kejap tak de current, kejap ada current lagi ...

Thanks
What model & year?
How much are the cost?
Need towtruck?

so just gdi variant more issues. i confused with theta just now. theta even more problems

my 2019 k3 mileage 180k km. just changed lower arm and front absorber.
and changed all 4 ignition coil plug.

can recommend any place to clean throttle body and reset tcm?
when driving slow, maintain throttle can feel engine loss power abit. not sure what is the cause.

Thanks.

Are you referring to Cerato?

What if for 2013-2019 Picanto, Ioniq Hybrid, 2017-2018 Sportage / Tucson CRDi ?

Yes...ECU issue mostly 1.6 cerato K3....easy and cheap fix.. no need change ECU

I believe sportage is using 2.0NU engine like K3 2.0...the rest tak tau

my 1.6 k3 2015 if stop in traffic aircond not cold

how ar

ecu problem havent surface yet

Maybe this is due to aircon compressor's flow valve jammed. Just go Ming Wah (if you're based in klang valley) to change the VALVE ONLY, not entire compressor. Normal aircon shop that dunno how to open up aircon compressor will propose to you to change the entire compressor and/or other components along.

Oso, check the radiator fan. The fan motor is 10yrs old this year so maybe it is on its out, if not out already.

Huh? What battery voltage?

Kia Forte car nice?

thank you very much! i will drop by next week

Not to forget another infamous problem is catalytic converter hancur by pieces and stuck blocking the exhaust air from channel out.

Starting last month my 2014 2.0 aircond not so cool. Every time when start driving after traffic you'll hear the aircond refrigerant start moving noise like just turn on aircond. But I see the aircond compressor got sticker like year 2022 or 2023 last owner just replaced...

I had the same issues with my Kia Spectra 2008. It was 1 component in the ECU. Sent it to 1 workshop in Sri Damansara, in out in out like 3x also the issue kept coming back. I got fed up and found 1 guy in Setapak near Giant and the problem was fixed. I gave the car to my bro-in-law after that

i lost the contact but it was in the middle row of Jalan 3/23a. Chinese owner and a lot of alternators in the shop. Good luck

TS.... 1 infamous issue with hyundai/kia with EPS system is the shaft bush worn out giving the steering knocking noise.

Very cheap spare part, i.e rm50 for the ori/genuine hyundai/kia star shaped bush, but workmaship is maybe 2-300, coz basically mech will have to dismantle the entire driver side steering column area just to take out the whole MDPS section to replace that tiny bush and reassemble everything after that.

My mech said the process is longer than changing timing belt and water pump. Work space is cramped on top of that.

leaky somewhere, ask kedai check pressure & topup first.
always use coldest (never adjust suka2) and calculate how many day can tahan.
till date mine tahan over 5 month, nothing to worry d.

Thanks for the info
How frequent do you need to replace this part?
Is it a common part number that shares amongst hyundai/kia models?

If not how to keep the economy jalan ? Barang yang x rosak, i take from my mechanic friend to resell it, when deal i tell my customer your old faulty one must give me, then i take the faulty one to my friend's besi buruk to exchange with a good one then resell, rinse and repeat

yes..my kia rio UB 2013 just yesterday replace ECU..MYR1800 hangus inclusive installation

ni betul..my kia having the same issue..how to solve the problem? buat bodo jaaa

it called steering coupler.... very cheap la.... less than RM10 also can get.... can last you many years...

many ppl say Kimchi car spare parts very expensive and difficult to get..... those days maybe la....

now with online e-commerce..... u can easily get whatever parts u need and cheap too if u want OEM.....

Depends on your luck and driving style. If dont change oso never mind according to my mech but just tak sedap pakai pasal bunyi klok-klok-klok setiap kali pusing stering. Oso steering got more free play when the bush has disintegrated.

Yes, it is a common/shared part for both hyundai/kia. Same MDPS system.

Boleh je pakai macam biasa kalu tak kisah sangat pasal bunyi kluk-kluk masa pusing stering. stering juga rasa macam kuat skit hentakannya pasal alas getah dah hancur. Cuma kena jaga perangai kereta bila freeplay banyak tu pasal tempat untuk alas getah tu sekarang dah kosong.

I have two kias.

2013 cerato. Mileage 27k km

2017 sorento diesel. Mileage 100k km

Both fine. Never heard in sorento group that need to change ecu.

Parts if buy from sc, expensive
3rd party shop cheaper.

I source parts from friend of friend in Korea. About 40% sc price

Bring to air-con shop to check whether you have enough gas.

Thanks.
