Are you aware of oil pump problem with Altima coupe 4 cylinder engine?
I bought a brand new Altima Coupe 2.5 (4 cylinder engine) last June. The engine is very noisy especially when it is cold. The dealer told me that it is normal. The sound comes from the oil pump. I didn't have this problem the first 5 000 KM. Is there anyone experiencing the same problem? Thank you in advance for your response.
