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)

• Timing chain stretch on the N20 four 2014–2016

  One source so far

  Check: Listen for a rattle at idle, and ask whether the timing chain and its guides have been replaced.

  Euro Premium Parts calls the timing chain a major weak point, with plastic guides that can break and wreck the engine. A seller's guide (unofficial)

• Oil use and leaks on the N20 four 2014–2016

  One source so far

  Check: Look for blue smoke when accelerating and oil around the valve cover, and ask how often the oil has needed topping up.

  Euro Premium Parts says oil use can start as early as 60,000 miles, from a faulty crankcase vent valve, worn valve stem seals or, at worst, worn rings, and lists coolant leaks at the back of the block and cracked boost hoses. A seller's guide (unofficial)

• Oil leaks on the N55 six 2014–2016

  One source so far

  Check: Look for oil around the valve cover, the oil filter housing and the oil pan.

  Euro Premium Parts lists leaks from these gaskets, and carbon on the intake valves. A seller's guide (unofficial)

Recalls

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

• 2014–2016 Recall 24V608000

  A badly sealed electrical connector on the water pump can let water in and short circuit. Dealers inspect and replace the pump and connector as needed and fit a shield. NHTSA

• 2014–2015 Recall 24V527000

  The driver's airbag inflator may explode when it deploys, because of a manufacturing defect. Dealers replace the driver's airbag. NHTSA

• 2014–2015 Recall 24V288000

  The head airbag's inflator can fail at a weld, leaking gas or rupturing. Dealers replace the head airbags. NHTSA

• 2015 Recall 15V148000
