Mitsubishi Grandis NA
Weaknesses, engine ratings and buying advice
Engine Overview
The Mitsubishi Grandis NA is available with 2 engine variants — from 136 to 165 hp.
VW-derived diesel from the Mazda/Mitsubishi cooperation (DW10BTED4 base from PSA) with 100–103 kW. Known for EGR problems and balance shaft wear. Timing belt every 120,000 km or 10 years. Oil change every 10,000 km is mandatory.
- !! Injector failure from 130,000 km
The common-rail injectors on the BSY/DW10BTED4 tend to wear and seize from 120,000–150,000 km. Faulty injection causes engine misfires and increased soot output. Replacement is costly.
Symptoms: Engine stumbling, misfires, cold-start difficulties, check engine light, rough running - !! Balance shaft wear from 120,000 km
The balance shafts on the 2.0 DI-D in the Outlander II/Grandis wear prematurely with neglected oil changes. Characteristic droning noise from the engine bay. Repair is very expensive.
Symptoms: Droning and vibration from the engine bay (especially in the mid-rpm range), check engine light - !! Timing belt failure from 120,000 km
The BSY/DW10BTED4 uses a timing belt drive with a 120,000 km or 10-year replacement interval. Exceeding it risks engine damage from valve collision. Replace the water pump at the same time.
Symptoms: Engine won't start, loud metallic noise on start attempt
+ 2 more engine weaknesses + vehicle weaknesses
Solid 2.4-litre naturally aspirated engine with MIVEC valve control and timing belt drive. No hydraulic lifters — valve clearance must be checked manually every 40,000–50,000 km. Very long-lived with regular maintenance.
- !! Timing belt failure from overdue replacement from 90,000 km
Timing belt must be replaced every 90,000 km or 6 years. If it breaks, catastrophic engine damage is unavoidable — interference engine with valve collision.
Symptoms: Engine suddenly won't start, loud metallic noise, engine damage - !! Neglected valve clearance causes damage from 80,000 km
No hydraulic lifters — valve clearance must be checked and adjusted every 40,000–50,000 km. Many workshops ignore this. Tight valve clearance burns valve seats.
Symptoms: Ticking from the valvetrain, power loss, increased fuel consumption, rough running
Vehicle Weaknesses
| Weakness | Cost | |
|---|---|---|
| Heater flap actuator failure The heater flap actuator fails and delivers only cold air from the front vents. Common from 80,000 km onwards; the servo motor in the dashboard must be replaced. Symptoms: Cold air despite heating being set, clicking noises behind the dashboard from 80,000 km | Low |
