CarComplaints.com Notes: We aren't rating the 2015 F-150 as "bad" yet, but there is an early trend of complaints about the transmission shifting roughly.
When accelerating, there is a loud chirping noise coming from the engine. The exhaust manifolds have warped. Very annoying sound and loss of power. Seems to be a common problem among other owners of the 3.5 eco boost. Very disappointing. Bolts cracked on both sides of the engine, both manifolds need replacing, and exhaust leakage.
