What owners say
X3 M
Overall
Owner sentiment is sharply divided, heavily dependent on the specific powertrain and ownership expectations. The high-performance X3 M and X3 M Competition models are praised for their exceptional power, engaging driving dynamics, and status as a practical yet thrilling performance SUV. However, this enthusiasm is tempered by very frequent and severe criticism regarding long-term reliability, exorbitant maintenance and repair costs outside of warranty, and significant depreciation.
Best version to buy
X3 M40i: This model is specifically recommended over the full X3 M for daily driving, striking a better balance between performance, comfort, and cost. It is described as offering ample power and a fun driving experience without the extreme harshness and running costs associated with the full M models.
Known issues
- Catastrophic engine failures (timing chain guide disintegration on N20 engines around 150,000 miles / 241,000 km): very frequent.
Macan
Overall
Mixed sentiment with a clear generational divide. The first-generation (2015-2018) Macan is frequently criticized for significant reliability issues, including transfer case failures, water pump problems, and expensive engine repairs, leading to high maintenance costs and owner frustration. The second-generation (2019-2024) and newer models receive more positive feedback for driving dynamics, build quality, and interior refinement, particularly in S, GTS, and Turbo trims.
Best version to buy
Macan S or GTS. The base 4-cylinder model is widely criticized for feeling underpowered and lacking the characteristic Porsche driving experience, with some owners comparing it unfavorably to a Volkswagen GTI or mainstream SUV.
Known issues
- Exorbitant maintenance and repair costs ("Porsche Tax"): very high dealer service rates, expensive parts (e.g., $3,000 for a complete headlight unit, $1,500+ for dealer oil changes). Frequency: very frequent.
- First-generation (pre-2019) reliability problems: transfer case failures, water pump issues, camshaft wear, rear inner CV boot leaks, exhaust downpipe cracks, AdBlue system faults, transmission failures. Frequency: very frequent.
- Base model performance criticism: underpowered 4-cylinder engine, uninspiring driving feel compared to higher trims, interior perceived as less luxurious. Frequency: very frequent.
The verdict

It has better fuel economy on its best-equipped version than the BMW X3 M, based on the data above. If power matters more to you than running costs, the BMW X3 M is worth a closer look instead.
