Hyundai i30 won't start after a long drive

Good day, I own a 2009 Hyundai i30 with a gasoline engine and 150,000 km on the odometer. After a long highway drive, especially at higher outside temperatures above 30 degrees Celsius, the car cannot be restarted after stopping. It starts without problems only after the engine has completely cooled down. What could be the problem?

Summary of the thread

A 2009 Hyundai i30 with 150,000 km on the odometer experiences starting issues after long drives, particularly in high temperatures. The car fails to restart until the engine cools down completely. A potential cause is a faulty crankshaft position sensor, which may malfunction when hot, preventing the engine from starting. Replacing or repairing this sensor could resolve the issue.

Check the crankshaft position sensor, as it can fail when hot and prevent the engine from starting. Let me know if this resolves the issue or if you need further assistance.

It has been replaced, the problem hasn't been solved.

Inspect the fuel pump relay and fuel pump itself, as they can sometimes fail when hot, causing starting issues. Ensure the relay is functioning properly and check for any signs of overheating or failure in the fuel pump. Let me know if this helps or if you have any other questions.
