What owners say
RLX
Overall
Owners consistently describe the RLX Sport Hybrid as an underrated, reliable, and genuinely enjoyable luxury sedan, praising its smooth power delivery, SH-AWD handling, and strong fuel economy for its size. The most common criticisms are low sales volume leading to parts availability concerns, a small trunk, and polarizing interior controls like the touchscreen HVAC and push-button transmission. Several owners call it their favorite car they have owned, with one reporting 112,000 miles of trouble-free driving and another at 188,000 miles with only routine maintenance.
Best version to buy
The 2018-2020 Sport Hybrid is the consensus best choice, with owners specifically recommending 2018-2020 for improved seats and 2020 for Apple CarPlay. The Sport Hybrid trim is strongly preferred over the non-hybrid PAWS models, with one owner stating to "skip the PAWS models" entirely.
Known issues
- 12V battery drains quickly and requires replacement every 2-3 years, especially if the car sits for more than a week: Frequency: recurrent. Timing belt service is expensive, quoted over $3,000 at a dealer: Frequency: isolated.
G80
Overall
Sentiment is predominantly positive, with owners praising the vehicle for its exceptional value proposition, luxurious and well-appointed interior, and strong reliability over multiple generations. The G80 is consistently described as a comfortable, quiet, and smooth-riding executive sedan that offers features and refinement comparable to established German rivals at a significantly lower price point. Positive long-term ownership experiences with models from 2011, 2015, 2016, and 2017 are noted, with many owners reporting trouble-free operation and becoming brand loyalists.
Best version to buy
Insufficient owner data available to declare a consensus "best" trim or powertrain. Feedback indicates strong appreciation for the 5.0L V8 model for its special character and the 3.3T/3.5TT engines for performance.
Known issues
- Dealership & Service Experience (U.S.): Long wait times for service appointments, poor communication, unprofessional treatment, and difficulty obtaining loaner vehicles. Frequency: very frequent.
- Instrument Cluster/Screen Failures: Digital gauge cluster displaying Korean characters, cutting out, or freezing, requiring replacement. Affects 2021+ models. A recall for 2025-2026 models for failing instrument panels is also noted.
- Oil Pressure Sensor Failure: Warning light illuminates despite correct oil level, leading to expensive repairs ($3,000+). Subject of a 2021 recall in South Korea but not in the U.S., leading to potential class-action investigation.
