Why did my Kia Rondo die after a puddle, or hesitate then jump?

Short answer: A Rondo that died after a puddle likely got water on wiring or into the intake. Hesitation then a jump forward points to a dirty throttle plate or a throttle or pedal sensor.

Symptom: The engine cut out in water, or hesitates then surges.

What to check first

1. Check the air filter and intake for water.
2. Dry connectors.
3. Clean the throttle body.
4. Read codes.

Likely causes

1. Wet wiring. Water splashed on connectors can short a sensor until it dries.
2. Water in the air intake. Water drawn into the air intake can damage the engine.
3. Sticky throttle plate or sensor. Carbon on the throttle plate, or a bad throttle or pedal sensor, can make the car hesitate then surge.

What it usually costs

Owners didn't post prices.

Is it safe to keep driving?

A car that surges forward is dangerous. Fix it before regular driving. Avoid deep water.
