Mercedes-Benz Service Questions, Answered
Which Mercedes-Benz repairs does the Sonny's warranty cover?+
Our 24-Month / 24,000-Mile Nationwide Warranty covers Mercedes-Benz repairs to brakes, electrical systems, air conditioning and heating, fuel, ignition and exhaust, on both parts and labor. Preventive maintenance like oil changes is not covered. Full terms are on our warranty page.
Why is my Mercedes-Benz sitting low on one corner?+
A leaking air strut is the most common cause when a Mercedes with air suspension sags or shows a car-too-low warning, especially on S-Class and E-Class models. The compressor then runs constantly to keep up and wears out, so early repair protects it. We trace the leak to its source.
Can I wait while my Mercedes-Benz is serviced?+
Most services are finished the same day, and you are welcome to stay in our comfortable waiting area, which has free WiFi. Book online in about 60 seconds and your Mercedes-Benz is on the schedule.
