What owners say

Sentiment is deeply polarized and varies significantly by generation and model. Long-term ownership satisfaction is frequently described as very high, with many owners reporting the car living up to or exceeding lifelong expectations. The 911 is often cited as

Extremely high maintenance and repair costs: Major engine or transmission failure can cost more than the car's value, and parts are exceptionally expensive. Frequency: very frequent.
Turbo lag in modern turbocharged engines (991.2, 992): Noted as a significant dynamic flaw, with criticism that reviewers downplay its presence. Frequency: recurrent.
Interior material quality and durability: Hard plastics, manual seats in base models, and specific issues like peeling door cards on 991 models left in the sun. Frequency: recurrent.
Numb electric power steering (991 and 992 generations): Criticized for lacking the feedback of older hydraulic systems. Frequency: recurrent.
Engine issues specific to generations: M96/97 engine issues (including IMS bearing) on older models (996, 997.1), susceptibility to carbon buildup on direct injection engines, and a noted case of a blown engine on a 996 under warranty. Frequency: recurrent.
