Summary Verdict
The 2001 Porsche 911 (996 generation) is a capable sports car with a generally solid mechanical foundation. However, potential buyers and owners should be aware of specific, well-documented issues, most notably the Intermediate Shaft (IMS) bearing failure in the 3.4L engine, which can be catastrophic if not addressed. Rear main seal leaks and cylinder head gasket issues are also noted concerns for the naturally aspirated engines. The Tiptronic transmission can experience fluid leaks. Electrical components like window regulators and ignition switches are not immune to failure. Despite these potential pitfalls, with diligent maintenance and awareness of these common problems, the 2001 911 can remain a rewarding and reliable performance vehicle.
