The flaws in the BMW B58 engine often involve using too much oil and experiencing leaks. Typically, spark plugs should be swapped out every 100,000 miles unless it's a copper type, in which case they should be changed every 30,000 miles. Air filters should be replaced every 15,000 to 30,000 miles, while the coolant needs refreshing at the 60,000-mile mark. Engine troubles might manifest in various ways, such as loose gaskets needing tightening, spark plugs dislodging and causing issues, and critical problems like engine overheating that could lead to fires and even explosions. Excessive oil consumption may prompt more frequent oil changes, and any oil leaks should be promptly addressed to prevent further damage.
Issues with the alternator, battery, starter, and fuses are common engine troubles found in the 2018 BMW B58.
