Catastrophic engine failure... not exactly what you want to hear no matter what you're driving, but especially so when you've just purchased a brand-new 2013 BMW M5 or M6.
BMW M6 Recalls
According to the M-obsessed boys and girls at M5Post.com, BMW has issued an immediate stop sale on new M5 and M6 (both coupe and convertible) models. The problem stems from the engine oil pump; if the pump doesn't supply the correct amount of oil to the engine's moving parts, "severe engine damage" is the likely result. That's not good at all.
