Just some sharing for my persona-2020 recent problem.
1. During driving suddenly the car no power and start slowing down, acceleration pedal no response when step further.
2. But if let go the acceleration pedal and re-step on the acceleration pedal, the power come back.
3. Tried few times when this happen, slightly step on brake pedal using left leg, the power came back.
Tried few mechanics to diagnose this problem but unable to settle it, as they said parts maybe not fully broken (since it is on an off happen, maybe once per an hour drive).
My friend as me to replace some fuse relate to brake and fuel pump. condition remain the same.
Until I saw a review in Lazada for the same problem, where he change the brake switch and everything settle.
Since brake switch not expensive, only rm2x+, I bought one brake switch and change it myself.
Monitor a few days, everything become normal again and the terrifying problem disappear.
This car doesn't have big problem in this moment and only clock 60k+ km, mostly small small parts easily broken or malfunction.
Such as lots of light bulb easily burned, plastic break off (visor bracket and some plastic parts found on floor which don't know where they came from) and steering wheel leather peel off (and my car only 4 years old).
small parts issues have always been proton's achillies heel, glad to see no accident came out of it
