BMW 4 Series (F32/F36) Buyer's Guide
Common Problems and Reliability
The first-generation BMW 4 Series (F32/F36, 2014-2020) split the coupe and convertible from the 3 Series lineup into a standalone model. Offered as the F32 coupe, F33 convertible, and F36 four-door Gran Coupe, it shared its platform with the F30 3 Series but featured a lower, wider stance and more aggressive styling. Engine options ranged from the turbocharged 2.0-liter four-cylinder (428i/430i) to the 3.0-liter inline-six (435i/440i), with the M4 using the S55 twin-turbo inline-six.
Engine choices: The N20/N26 four-cylinder in early 428i models (2014-2015) is known for timing chain guide failures. The B46/B48 four-cylinder in later 430i models (2016+) is significantly more reliable. The N55 six-cylinder in the 435i is a proven engine but the B58 in the 440i (2016+) is the one to buy — it's widely regarded as BMW's most reliable modern engine. The six-speed manual was available on rear-wheel-drive models through 2019; the eight-speed ZF automatic is excellent across all variants.
What to look for: Verify that the timing chain was addressed on 2014-2015 N20 models — the plastic guides can fail, causing catastrophic engine damage. The B58 and ZF eight-speed are robust but require regular oil changes every 5,000-7,500 miles. Check the sunroof drains for clogs. The N55 engine has charge pipe failures that cause sudden boost loss. On M4 models, crank hub spin is a well-known issue. A well-maintained 440i Gran Coupe with the B58 is one of the best used sport-luxury values available.
About the F32/F36
The 2014-2020 BMW 4 Series (F32/F36 generation) replaced the previous 3 Series coupe and introduced a distinct model line for two-door and four-door coupe body styles. This generation is defined by its sleeker, more aggressive styling compared to the sedan it was derived from, and it was offered as a two-door coupe (F32) and a four-door Gran Coupe (F36). Powertrain options centered on a 2.0-liter turbocharged four-cylinder in 428i and later 430i models, and a 3.0-liter turbocharged six-cylinder in 435i and later 440i variants. All engines paired with an eight-speed automatic transmission, with rear-wheel drive standard and xDrive all-wheel drive available across most trims.
The 2014-2020 BMW 4 Series suits buyers seeking a sporty, premium coupe with sharp handling and a refined interior. The Gran Coupe body style adds four doors and a hatchback for greater practicality without sacrificing the coupe-like roofline. This generation is generally regarded as a strong used buy for its balanced driving dynamics and modern features, though early models may require attention to common BMW maintenance items such as cooling system components and valve cover gaskets.

Frequently asked questions
Which 4 Series engine should I buy?
The B58 inline-six in the 440i (2016+) is the clear winner — it's powerful, smooth, and BMW's most reliable modern engine. Avoid 2014-2015 N20 four-cylinders unless timing chain was addressed.
Is the Gran Coupe practical?
The F36 Gran Coupe has a hatchback-style trunk with a large opening, making it surprisingly practical with 17 cubic feet of cargo space — nearly wagon-like utility in a coupe shape.
What's the difference between 435i and 440i?
The 435i uses the N55 engine (300 hp, single twin-scroll turbo, introduced 2014). The 440i uses the B58 (320 hp, improved reliability, better tuning potential). The 440i is the better choice.
