What owners say

S5

Overall

Sentiment is sharply divided by generation. The B8.5 (supercharged V6) and B9/B9.5 (turbocharged V6) generations receive generally positive feedback from long-term owners, who praise the driving experience, comfort, and timeless styling. However, these generations are associated with several known, potentially expensive mechanical issues.

Best version to buy

Insufficient owner data available to declare a single "best" version. For the B9/B9.5 generation (2018-2024), the Sportback body style is frequently mentioned for its superior practicality.

Known issues

  • **B10 Generation (2025+):** Persistent check engine lights with numerous fault codes, leading to repeated dealership visits and extended downtime. Frequency: very frequent.
  • **B9/B9.5 Generation (2018-2024) with 3.0T Engine:** Water pump failure, often leading to coolant migration. Frequency: very frequent. PCV (Positive Crankcase Ventilation) valve failure. Frequency: very frequent.
  • **B8.5 Generation (2013-2016) with Supercharged V6:** Water pump failure. Frequency: recurrent. Wheel bearing failures. Frequency: isolated.

Stinger

Overall

Mixed to positive sentiment, with a clear distinction between engine variants. The 3.3L twin-turbo V6 (TT) models are widely praised for their strong acceleration, smooth power delivery, and compelling value proposition as a sporty, practical liftback. Owners report high satisfaction with the car's unique styling, engaging driving dynamics, and spacious, feature-rich interior.

Best version to buy

3.3L Twin-Turbo V6 GT models (GT, GT1, GT2). The V6 engine is consistently highlighted as transformative, providing the power and responsiveness that defines the car's sporty character.

Known issues

  • Poor rear visibility: very small rear window, thick C-pillars creating significant blind spots. Frequency: very frequent.
  • Transmission behavior in manual/sequential mode: slow to respond to manual shift inputs, computer forces upshifts, downshifts take too long. Frequency: recurrent.
  • Turbo lag (2.0L/2.5L 4-cylinder models): significant delay in power delivery, sluggish acceleration from a stop. Frequency: recurrent.
