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. |

QUOTE(speedy3210 @ Apr 25 2025, 08:26 AM) TS.... 1 infamous issue with hyundai/kia with EPS system is the shaft bush worn out giving the steering knocking noise. Thanks for the infoVery 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. How frequent do you need to replace this part? Is it a common part number that shares amongst hyundai/kia models? |

QUOTE(mystvearn @ Apr 25 2025, 01:07 PM) I have two kias. Thanks.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 Your Sorento is CRDi 2.2? What's the FC? How frequent do you change battery? How much do you spend on each donut? 17" & 19" price difference quite huge it seems. |
