Phoenix is demanding on a BMW 740LI. 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 BMW 740LI problems owners report most often, what each one looks like from the driver's seat, and how we fix it.

BMW 740LI Maintenance in Phoenix Heat
- Test the 740LI 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 740LI 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
