Watch out

Faults owners and the press report, and how to spot each one.

• Water trapped in the convertible's rear side panels All years

  Check: Listen for water sloshing in the rear side panels while driving, run each rear window and the roof, and look for water or a musty smell in the corners of the trunk. Ask whether the drains have been cleared.

  BMW of North America's bulletin says the rocker trim and underbody panel can sit too tight against the drain plugs, so water fills the lower rear side panels and can corrode the rear window regulators and motors, then reach the trunk's audio amplifier. It extends coverage of the drain repair to 15 years or 150,000 miles from first delivery. On a British owners' forum, owners of four convertibles in three threads report a rear window or the roof stopping working from water in the panel, and another found water running out of a sill after a car wash. BMW, owners' reports (unofficial)

• Coolant leaks on the B48 four 2017–2020

  Check: Look for coolant at the upper radiator hose and the oil filter housing.

  Euro Premium Parts reports occasional leaks at these two points. A seller's guide (unofficial)

Recalls

Newest first. Ask the seller for proof the work was done, or check the VIN with NHTSA.
