However, these generations are associated with several known, potentially expensive mechanical issues.

G70
Overall
Sentiment is sharply divided, creating a high-risk, high-reward ownership profile. The vehicle is widely praised for its exceptional value proposition, offering strong performance (particularly from the 3.3T V6), a well-appointed interior, and engaging driving dynamics at a price point significantly below established German competitors. Many owners express deep satisfaction, citing the car as a "blast" to drive and a remarkable performance bargain, especially when purchased used with steep depreciation.
Best version to buy
The 3.3T Sport Prestige (or similarly high-trim) model is most frequently recommended. Owners highlight the superior power and performance of the twin-turbo V6 over the 2.0T and 2.5T four-cylinder engines.
Known issues
- Dealership service and corporate support problems: extremely long wait times for appointments (4-6 weeks), refusal or inability to provide loaner vehicles, unresponsive customer service, parts availability delays. Frequency: very frequent.
- Electrical and sensor malfunctions: false forward collision/Blind Spot Monitoring warnings, sensor failures (often attributed to stone chips), complete driver-aid system shutdowns, intermittent fault lights. Frequency: very frequent.
- Interior build quality and rattles: headliner and sunroof rattles, creaking doors in cold weather, failing power seat switches, vibrating speakers, loose objects in headliner. Frequency: very frequent.
