Ford Mustang Ecoboost Problems

Ford Mustang comes with different types of engines and the 2.3 Ecoboost is one of them. The Ford Mustang Ecoboost is not only powerful and performs outstandingly, but it is also efficient and emits fewer greenhouse gases. But as expected, it also comes with several issues. So, what are the common problems with the Ford Mustang Ecoboost?

The Ford Mustang Ecoboost has experienced several issues over the years, including engine overheating, carbon buildup, head gasket failure, engine oil leaks, and the car vibrating when driving. The good news is that most of these problems can be averted by properly maintaining and repairing your Mustang.

What are the common problems with Ford Mustang Ecoboost?

Engine overheating

The first and most common problem that Ford Mustang Ecoboost cars go through is engine overheating. This is a common problem across Ford models. It is usually caused by oil and coolant leaks. To fix this issue, you will have to start by fixing or replacing bad coolant or head gaskets.

High exhaust temperatures

Another common problem that users of this car experience are the car running hot. In 2015, Ford had to issue several recalls because of hot underbody temperatures. This is after Ford realized that the exhaust was hotter than normal. On top of that, it caused concern that the high temperatures made fuel vapor lines, parking brake cables, and fuel tanks fail.

Ford made adjustments by installing ideal heat shields. Another option is to upgrade the intercooler so that the exhaust doesn’t heat up a lot and cause damage to other parts.

Carbon buildup

If you drive a Ford with the Ecoboost engine, this is a problem that you cannot avert. This is because it comes with a direct-injection engine and not a port injection. The direct-injection engine has a flow as the fuel flows directly into the cylinders, while the port-injection engine sprays the fuel into the intake ports.

So, since there is no fuel flowing over the intake valves to clean them, the carbon deposits usually stick to the valves and cause carbon buildup. That’s why it is recommended to clean or inspect your intake valves every 100,000 miles for such deposits. Some of the signs of carbon build-up are engine misfire, power loss, and rough idling.

Head gasket failure

Head gasket failure is very common on the Ford Focus 2.3 Ecoboost engine. However, some users have also reported Ford Mustang 2.3 Ecoboost model to experience similar signs. But since the Ford Mustang 2.3 Ecoboost is still new, the cases are very few. Replace the head gasket if it starts showing signs such as engine overheating and white smoke coming from the tailpipe.

The car vibrates when driving

This issue is common in the 2016 Ford Mustang Ecoboost models. Many drivers complained about their cars vibrating when they hit over 60 mph. Most people guessed that it was because of an imbalanced driveshaft, while others suspected the rear-end assembly. Instead of guessing, take the car to a mechanic to fix the problem.
