Trouble Spots
Consumer Guide's® Auto Editors have scoured repair bulletins and questioned mechanics to search
for commonly occurring problems for a particular vehicle. In some cases we also give possible manufacturer-suggested
solutions. In many instances these trouble spots are Technical Service Bulletins posted by the manufacturer,
however, we have our own expert looking at additional vehicle problems.
Engine knock:
The 3.2-L (S54) engine reportedly suffers connecting-rod-bearing failures at a higher than normal rate, perhaps because some car owners are not using the required 10W-60 synthetic oil which is not readily available in the aftermarket. BMW is extending the warranty to 6 years/100,000 miles, (2001-03)
Exhaust system:
BMW issued a voluntary emissions recall to replace faulty crankshaft position sensors. (1999)
Steering noise:
Steering wheel buzzes or vibrates due to poor isolation of the power steering pump. (1999)
Transmission leak:
Manual transmissions' drain plugs may leak. BMW also suggests replacing the fill plug. (1999)
Transmission slippage:
Transmission may slip and/or check-engine light may glow due to torque converter clutch (TCC) slipping and/or TCC solenoid failure. (1999)
