A 2017 Ford F-150 is now 9 years old, so an average example has covered around 121,500 miles. A mid-run car · most launch faults had been addressed by this point, and wear items are the main risk at this age. Check the state safety inspection and service history alongside the documented faults below, which are sorted by whether a 2017 car has usually reached the mileage where they appear.

Build my inspection planThe 5.0L V8 and 3.5L EcoBoost are both strong; the EcoBoost needs cam-phaser and water-pump attention with age.
Many are fine, but some shift harshly; a test-drive and fluid check are essential.
The aluminum won't rust like steel, but watch for corrosion where dissimilar metals meet.
The 2.7L EcoBoost uses a different architecture and is generally less susceptible to the cam phaser and timing chain stretch issues that plague the 3.5L variant. However, early 2015-2017 models can suffer from oil pan leaks due to the plastic pan design. Always check the undertray for fresh oil residue.
Inspect the rear leaf springs and shock absorbers for premature wear or sagging. Additionally, check the integrated trailer brake controller on the dashboard for fault codes. Heavy towing can also accelerate wear on the rear differential, so listen for whining noises from the rear axle during a short test drive.
Engage the four-wheel-drive system on a loose surface or during a straight-line test on the forecourt. The transition from two-wheel drive to four-wheel drive should be seamless, with no clunking or hesitation. If the dashboard displays a warning, suspect a faulty shift motor or a vacuum leak in the hubs.
