Recalls & safety

Whether a recall is still open on a specific car depends on its VIN. Check it free at NHTSA's VIN lookup (nhtsa.gov/recalls), or ask the seller for proof the repair was done.

Pros & cons

Pros

  • Engaging handling with a refined ride; quattro all-wheel drive available.
  • Upscale, solidly built interior that feels a class above its price.
  • Punchy, efficient 2.0T (and earlier 1.8T) engines.
  • Strong crash-test results and modern safety tech on later cars.

Cons

  • Premium fuel required, and German parts and service raise running costs.
  • The EA888 2.0T can develop coolant leaks and intake carbon buildup.
  • Early cars (2015-2016) carry fuel-leak and Takata airbag recalls, confirm they were completed.
  • Cramped rear seat and modest cargo space.

Move your cursor along the line to see the estimated value for any year.

Curve anchored at the entry-trim base MSRP ($31,950). Higher trims started higher (up to $40,700), and options added more.

The curve's data ends 10 years in, so the line levels off after that. Treat the tail as a floor, not a forecast: asking prices for older cars depend mostly on condition, mileage, and the current market, and often sit well above it.
