Check against the official notice below — it lists the full affected range.
Mercedes-Benz is recalling certain 2011-2012 model year S550, S550 CGI, S63, S600 Bi-Turbo, S65 AMG, S550 4-Matic, S550 CGI 4-Matic, and S400 Hybrid vehicles manufactured between March 3, 2011, and July 30, 2011. The tire pressure monitoring system (TPMS) in these vehicles has a defect where if all four wheel sensors malfunction or go missing at the same time, the system will provide an initial warning but will not automatically repeat that warning on subsequent engine starts, leaving drivers unaware that the monitoring system is not working.
This defect creates a safety risk because drivers may unknowingly operate vehicles with incorrectly inflated tires, which can lead to sudden tire failure and increase the likelihood of a crash. To remedy the problem, Mercedes-Benz dealers will reprogram the tire pressure monitoring unit at no cost to owners. Affected owners should contact Mercedes-Benz at 1-800-367-6372 to schedule this service.
