After 3 years of having the JAC JS4 I tell you my experience with this SUV.
The JAC JS4 is a stable SUV with fairly economical performance.
By the time I was 3 years old, I had traveled 42,468 km, which gives us an average per year of 14,156 km.
The gasoline efficiency since the last refueling (traveling sections in the city for the most part) is 13.1 km/liter or 49.58 km/gallon.
The maintenance carried out during these 3 years has been the common engine oil and filter changes: every 5000 km.
In addition to changing the air filter, fuel filter, injector cleaning, tire rotation, engine scan every 3 months without finding any faults.
I have gone ahead to buy the flat belt for the alternator and air conditioning to avoid having the car stall.
I didn't find the alternator band immediately at the original parts dealer, it took a month to arrive.
Otherwise I didn't have any additional problems.
