Known Daihatsu Rocky (later) faults
Every fault below is documented specifically for this model — researched and verified before it’s published.
01K3-VE Timing Belt Failure (Interference Engine — Engine Destruction Risk)
CriticalCommonEngine $600–$7,500 to fix
The J102 Terios uses the K3-VE 1.3-litre engine with a rubber timing belt in an interference layout. If the belt snaps, pistons and valves collide and the engine is destroyed. Belt replacement is due at 90,000 km or 6 years, but the majority of J102 Terios imported to NZ/AU arrive with no documented belt history. This is the single highest-risk mechanical item on the J102 and should be treated as overdue unless proven otherwise.
Symptoms to notice
Engine stops suddenly with no warning while driving (belt snapped)
No compression on any cylinder after belt failure
Ticking or slapping from the belt area if the belt is fraying before failure
Engine cranks but does not fire if timing has jumped a tooth
What to check
Confirm timing belt replacement history before purchase — if unknown, budget for immediate replacement. Inspect belt condition through the inspection cover if accessible. Check tensioner and idler pulley for age-related cracking or bearing roughness.
Where to look: Front of engine, under the timing belt cover on the passenger side of the engine bay
Ask the seller
“When was the timing belt last replaced, and can you show the invoice?”
“If belt history is unknown, what is the current odometer reading?”
“Has the engine ever cut out or lost power suddenly while driving?”
02Rear Trailing Arm Bush Collapse
MinorCommonSuspension $250–$700 to fix
Rear trailing arm bushes harden and collapse causing rear knocking and imprecision.
Symptoms to notice
Knocking from rear suspension over rough surfaces
Imprecise rear handling feel
What to check
Inspect rear trailing arm bushes for cracking. Push the arm — any movement indicates collapsed bushes.
Where to look: Rear suspension trailing arm mounting points
Ask the seller
“Has the rear trailing arm bush collapse been inspected or repaired?”
