Consumer Description

Car will not measure oil past 20%. Seems like lots of 2020 models have a faulty production oil pump. Car is now out of warranty and dealer charged $5000 to fix the issue but do not know 100% if oil pump replacement will fix it. BMW changed the oil pump in the later models but did not mention anything about any recalls or replacements. Unacceptable.
