What owners say
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.
S90
Overall
Mixed to positive sentiment, heavily dependent on model year and powertrain. The S90 is widely praised for its exceptional value on the used market, offering flagship-level comfort, spacious interiors, industry-leading safety systems, and an acclaimed Bowers & Wilkins audio system at a significant discount from MSRP. Long-term owner reports frequently highlight superb highway comfort, excellent seats, and strong fuel economy from diesel (D4) and base gasoline (T5) variants.
Best version to buy
2018 and newer model years are strongly recommended over 2016-2017 models, as most early teething issues (e.g., air compressor faults, software bugs) were reportedly addressed. For gasoline models, the simpler T5 engine is suggested over the more complex T6 for reliability.
Known issues
- ⚠Rear suspension air compressor failure: triggers diagnostic codes and blown fuses, subject to a 7-year/unlimited-mileage extended warranty for 2017-2020 models. Frequency: recurrent.
- ⚠Pilot Assist system imperfections: described as "pinballing" between lane markings, poor handling of highway merges/off-ramps, and positioning too close to the center line. Frequency: recurrent.
- ⚠Brake rotor warping: premature warping and vibration, particularly on front axles. Frequency: recurrent.
