Phoenix is demanding on a Audi S8. Extreme heat, stop-and-go traffic and long highway miles on the I-17, the 51 and the Loop 101 all show up as wear. Below are the Audi S8 problems owners report most often, what each one looks like from the driver's seat, and how we fix it.

Audi S8 Maintenance in Phoenix Heat
- Test the S8 battery before every summer, and replace it proactively around the 3-year mark
- Follow the severe-service schedule for oil and fluids, since Phoenix heat and traffic count as severe use
- Inspect S8 brakes and tires twice a year; heat and stop-and-go driving wear both quickly
- Check coolant level and condition, and inspect belts and hoses for cracking
- Service the A/C early; a weak system rarely fixes itself
- Replace wiper blades and check lights, since sun destroys rubber and plastics
