Specs side by side
What owners say
X5
Overall
Sentiment is mixed and heavily dependent on the specific generation, powertrain, and ownership approach. For the current G05 generation (2019+), the inline-six (B58) powertrain is very frequently praised for its performance and noted reliability, with some owners calling it "super reliable" and "the best inline 6 in the world." The driving experience is consistently highlighted as a major strength, described as "performance oriented" with superior ride, handling, and road feel compared to key competitors. However, significant criticism is directed at the plug-in hybrid variant (50e), with one detailed owner report citing a "terrible" experience involving multiple, repeated drivetrain failures and extensive dealership visits.
Best version to buy
Insufficient owner data available to declare a single "best" version. Strong, recurrent praise is directed at models equipped with the B58 inline-six engine (e.g., xDrive40i), which is lauded for its reliability and performance.
Known issues
- . For long-term ownership (5-10 years), setting aside a significant fund for maintenance and repairs is considered mandatory. A pre-purchase inspection by a specialist is critical, especially for older or high-mileage examples.
RX
Overall
Overwhelmingly positive sentiment centered on exceptional long-term reliability, comfort, and low ownership costs. The RX is consistently described as a "bombproof," comfortable, and quiet vehicle built to last well over 150,000 miles with minimal issues. Owners report high satisfaction with its role as a refined, practical daily driver and family vehicle.
Best version to buy
For the 2016-2022 generation, models equipped with the naturally aspirated V6 engine (RX 350) are highly recommended for their proven, bulletproof reliability. For the 2023+ generation, the plug-in hybrid RX 450h+ receives strong praise for its combination of smooth EV driving, ample power (0-60 in 5.8 seconds per owner-cited review), and efficiency, though its high cost is noted.
Known issues
- Dated infotainment system (pre-2023 models): described as outdated, with inferior connectivity and interface. Frequency: very frequent.
- Interior material quality concerns (2023+ redesign): perceptions of cheaper-feeling materials, hard plastics, and a less luxurious feel compared to previous RX generations and some competitors. Frequency: recurrent.
- 12V battery issues (2025 RX 450h+): multiple reports of 12V auxiliary battery failures or draining at low mileage, suspected to be a manufacturing defect. Frequency: recurrent.
