I've owned a Waja 1.8 since new. Now the car is more than 10 years old and has clocked 130k km. This car started to give problems after the warranty period of 2 years expired. I've encountered all the problems as mentioned by other 1.8 owners.
Engine spare parts prices are more expensive than most Japanese car, but if you can find a good shop, the price is reasonable.
I have also encountered a gearbox problem a few times with the GB indicator on, and the gearbox goes into the safe mode. Most of the electronic parts related to the GB have been replaced like TCU, solenoid valve etc, and the transmission is OK for a few years. Lately the problem occurred again, and the mechanic told me that the GB is fine and he needed to check the wiring/grounding on some of the electrical parts that send the error code to the TCU. Now the car is fine.
I have also checked on the web the battery spec for the Renault f4p engine, and the capacity is much bigger than what Proton specified for the Waja 1.8 (65 amp vs 55 amp). I strongly feel that all the electrical related problems with the Waja 1.8 started with this underrated battery, which damaged many electrical component like TCU, ECU, ABS module, and all kinds of engine sensors.
I hope other Waja 1.8 owners can share my experience with this car, as I am still keeping this car till today. You can email me at azlanhssn@yahoo.com if you wish to contact me.
If you ask the wrong workshop, they will ask you to change all 4. Actually you need to open it and see which one of the rubbers has broken, and that's the one you need to change.
