Owners of cars with this powertrain often encounter oil leaks. The weak points for leaks are the P-shaped gasket and the crankshaft seal. The second most common problem is engine misfires due to clogged fuel injectors. The cause of excessive oil consumption is usually the oil control rings, which can be resolved by replacing them. After 150,000 km, the single-row timing chain may stretch and require replacement.
