2015 Ford Explorer died twice in two months

[Danny]

In my family, one of my uncle recently got the 2015 Ford explorer 2-3 months back and it died twice on the road: Once while driving, once in the mall parking. Though after all he restarted the car after few minutes it started back like normal, but I mean why car shutdown by itself without any reason or failure and then start working fine again. Baaah.

Any explorer fans here encounter same.....? What is the remedy....? Any big risk.....?

Ask your uncle to go with Japanese or German cars. American cars still lacks in reliability big time.

But 2-3 months old car sound something seriously wrong and dealer should diagnose it properly.

This must be due to some advance electronic malfunction happening. Visit the dealer and they can plug the diagnostic tool to read the error code recorded in the car computer and then fixing that root cause. It could be simple air filter installation is loose and car passing thru bump must have taken more air making the lean air-fuel mixture and shutting off the car as a safe-mode.

Almost all modern cars since 2010 and above deployed with safe-mode and it's a blessing and curse at the same time. It saves the car from bigger damage and expense but leaves such minor bugs floating around causing the safe-mode to trigger on the tiniest issue.

Hi Danny,

The type of symptoms you describe is almost always fuel related, and if the affected Explorer has a gasoline engine, the problem occurs when the fuel in the lines starts to boil, or vaporize, and especially if the fuel lines run close to particularly hot engine components.

The problem is known as a “vapor lock”, and when it occurs, the pressure in the fuel system drops dramatically, which starves the injectors of fuel.  The effect is as you describe- the engine just shuts off, but if the problem were related to the electrical system, there would be some sort of warning in the form of an illuminated warning light right before the engine shuts off. In these cases, the warning light, such as the CHECK ENGINE light will remain illuminated, even if the vehicle starts again.

However, in the case of a vapor lock, there won’t be warning lights before the engine shuts off, but if the engine remains switched off for a few minutes, the fuel in the lines will cool down and re-condense into a liquid.

This is why the Explorer started normally each time a few minutes after it shut off, and unless the fuel lines are insulated against excessive heat, the problem will occur again. I hope this helps.

Im curious to know if American cars are really so bad in reliability as a brand new as well......?
