Phoenix is demanding on a Mercedes-Benz GL-Class. 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 Mercedes-Benz GL-Class problems owners report most often, what each one looks like from the driver's seat, and how we fix it.
Most Common Mercedes-Benz GL-Class Problems in Phoenix
Ranked by owner complaints filed with the National Highway Traffic Safety Administration (NHTSA) for the GL-Class. Counts reflect reports filed, not the share of vehicles affected.

What it looks like:
- Airbag or SRS warning light

What it looks like:

Mercedes-Benz GL-Class Maintenance in Phoenix Heat
- Test the GL-Class 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 GL-Class 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
