At what mileage do F150s start to have problems?

Ford F150 trucks are known for their reliability and durability, but like any vehicle, they can experience issues as they accumulate mileage. According to industry experts, F150s generally start to show more significant problems around the 100,000-mile mark.

Common F150 Problems by Mileage

The Ford F150 is a robust and well-engineered truck, but certain components and systems can begin to wear out or malfunction as the mileage increases. Here's a breakdown of when common F150 problems tend to arise:

• 50,000 to 100,000 miles: At this mileage range, F150 owners may experience issues with the transmission, such as slipping or delayed gear changes. The brakes and suspension components may also require more frequent maintenance and replacement.,li>
  
• 100,000 to 150,000 miles: As the F150 approaches and exceeds 100,000 miles, more significant problems can start to surface. These may include engine issues like oil leaks, misfiring, or reduced fuel efficiency. The electrical system and various sensors may also begin to fail.


• 150,000 miles and beyond: At higher mileages, F150 owners may encounter more extensive problems, such as transmission failures, differential issues, and even engine replacements. Rust and corrosion can also become a concern, especially in areas with harsh winter weather.,

It's important to note that the specific mileage at which problems arise can vary depending on factors such as driving conditions, maintenance history, and individual vehicle usage. Regular maintenance and prompt attention to any issues can help extend the lifespan of an F150 and minimize the likelihood of major problems.

What is considered high mileage on a Ford F-150?

For a Ford F-150, over 100,000 miles is generally considered high mileage, though F-150s are known for their durability and can be reliable well beyond this point with proper maintenance. Vehicles with more than 20,000 miles per year on average are also often labeled as high mileage. 
What constitutes high mileage

• Over 100,000 miles: This is the general threshold for high mileage, at which point components like the engine and transmission may start to show wear. 
• Over 15,000 miles per year: A good rule of thumb is to consider a truck with more than 15,000 miles on it per year of its age as high mileage. 
• 20,000+ miles per year: A truck driven more than 20,000 miles annually is considered high mileage. 

Important considerations for high-mileage F-150s

• Maintenance history: A well-maintained F-150 with over 100,000 miles can still be a great value. A solid maintenance record is crucial. 
• Potential for more expensive repairs: As mileage increases, the likelihood of needing more significant and costly repairs for components like the engine, transmission, or other parts goes up. 
• Engine and transmission specifics: Certain F-150 engines, like the 3.5L EcoBoost, have known potential issues like cam phasers, and some transmissions can have issues with the CDF drum and valve body, notes this YouTube video. 
• Body and overall condition: A solid body, even with high mileage, can be a good indicator of a well-cared-for vehicle. 

What are bad years to avoid Ford F-150?

Years to avoid when buying a used Ford F-150 include 2004–2008, which had widespread engine and transmission issues, especially with the 5.4L V8, and 2015–2017, which had transmission problems and, in some cases, electrical or security issues. Other years to be cautious about are 2010, 2013, 2016, and 2021, which had their own specific problems like engine, transmission, or electronic issues.

Ford F-150 years to avoid

• 2004–2008: These models, part of the 11th generation, are often cited as problematic due to issues with the 5.4L Triton V8 engine (spark plug ejection, cam phaser failure) and the transmission. 
• 2010: The 2010 model continued to have some of the 5.4L engine's issues, along with problems with the 6-speed transmission and other components like windows and door handles. 
• 2013: This year had issues with the 6-speed automatic transmission, such as hard shifting and slipping. 
• 2015–2017: These model years are known for transmission problems, especially the 10-speed transmission in later models. The 2015 model had a bumpy ride, while the 2016 model experienced stalling and electrical issues. 
• 2021: The first year of a new generation often comes with glitches, and the 2021 model is no exception, with reported issues related to its electrical system, infotainment, and the new hybrid powertrain.

Important considerations

• This list is based on common complaints; any used vehicle can have unique issues. 
• Always have a used truck inspected by a trusted mechanic before purchasing. 
• Research specific model years and their engines for known problems, such as the 2017–2020 3.5L EcoBoost's cam phaser issues, which can be fixed, but a pre-purchase inspection is still essential. 

Are F150s reliable after 100k miles?

Ford pickup trucks are built as robust as possible. This quality build helps them travel well-over 100,000 miles. Customers looking for an affordable and reliable pickup truck can even consider used Ford F-150s between 100,000 and 120,000 miles!

What mileage does a Ford F-150 become unreliable?

Understanding the lifespan of the Ford F-150 is crucial for potential buyers. On average, the F-150 can last between 200,000 to 300,000 miles, with some models even reaching 400,000 miles.
