Problem 1
Kia Picanto: Timing chain tensioner rattle on a cold start
What goes wrong
The timing chain tensioner wears, typically around 100,000-130,000 km.
How to check it yourself
Listen for a rattle in the first seconds after a cold start and read cam/crank correlation codes.
The usual fix
Replace chain, tensioner, and guides.
Signs: Rattle on cold start, Check engine light
Fault codes: P0016, P0017
Problem 2
Kia Picanto: Weak handbrake from corroded rear calipers
What goes wrong
Water gets into the rear calipers or drums and the handbrake mechanism corrodes.
How to check it yourself
Test whether the handbrake holds the car on a slope and check that both rear wheels lock; look at the handbrake mechanism for rust.
The usual fix
Free and lubricate or replace the caliper or handbrake mechanism and adjust the cable. A weak handbrake is an MOT and safety issue.
Signs: Brake warning light
Problem 3
Kia Picanto: Loose crankshaft pulley bolt or failing crank sensor
What goes wrong
On early 1.0 engines the crankshaft pulley bolt can work loose and the crank position signal becomes erratic; left alone the crankshaft can break.
How to check it yourself
Look for a wobbling crank pulley with the engine running and read crankshaft sensor codes.
The usual fix
Stop driving if the pulley wobbles. Replace the pulley and bolt (and the crankshaft sensor if faulty); a damaged crankshaft nose is an engine repair.
Signs: Hard starting, Rough idle, Loss of power, Stalling
Fault codes: P0335, P0336
