Anyone experienced passenger door failure? Before this it was only left back passenger door cannot open from inside, then it totally fail cannot open at all, now right back passenger door cannot open from inside, only able to open from outside, driver side and front passenger side functioning fine, could it be central lock system problem? Any workshop recommendation?

One side cannot unlock at all, one side cannot open from inside, but can unlock and can open from outside, there is a child safety lock installed to the door, i tried to unlock it but cant push it to unlock side

Hi, asking on behalf of sister's kenari ez auto year 2000, mileage around 110k. Beginning problem was car suddenly die in middle of the road when driving, but still can start immediately afterwards, engine light and battery light flashing on dashboard, replaced alternator, battery, spark plug, clean throttle, flushed radiator (coz there's some yellow brownish mud type of dirt in the radiator system?) Then, it turned into second stage of problem, car start to experience "minor" jerk when stopping in front of traffic light & jerk again when trying to pickup after traffic light turn green. Then it became "major" jerk and car keeps vibrating vigorously during idle after the jerk, rpm drop to very low and suddenly rise up alot when switching from idle to drive, then jerk and car stalled. Occasionally car jerk when switched to reverse and stall then suddenly die. Workshop say ignition coil problem and quote RM500 to replace all 3 coils, need opinion to see if the problem is really with ignition coil or something else?

Hi, just saw ur reply and thanks for the suggestion, after few run to workshops, eventually one of the workshop mentioned could be ignition coil problem, but quote RM500 for 3 coils, so i end up buying online and replace them myself, the car runs ok, until... later my sis finds the car taking very long time to start moving after idle, after she starts the car, it takes around 15-30min to move when shift gear to D, but if gear R it can reverse just fine, if gear D2 it can start to move slowly and later on pickup fine, just that cannot straight to gear D after idle, any idea what could be causing it? is it gearbox issue?

The problem was eventually solved by changing entire gear box, bought a used one at RM500+, total cost is around 1k ><
