Mercedes-Benz (German pronunciation: is a German manufacturer of automobiles, buses, coaches, and trucks. Mercedes-Benz is a division of its parent company, Daimler AG. Mercedes-Benz traces its origins to Karl Benz's creation of the first petrol-powered car, the Benz Patent Motorwagen, patented in January 1886 and Gottlieb Daimler and engineer Wilhelm Maybach's conversion of a stagecoach by the addition of a petrol engine later that year.
The Mercedes automobile was first marketed in 1901 by Daimler Motoren Gesellschaft. The first Mercedes-Benz brand name vehicles were produced in 1926, following the merger of Karl Benz's and Gottlieb Daimler's companies into the Daimler-Benz company.
Mercedes-Benz has introduced many technological and safety innovations that later became common in other vehicles. Mercedes-Benz is one of the most well-known and established automotive brands in the world, and is also the world's oldest automotive brand still in existence today.
Since its inception, Mercedes-Benz had maintained a reputation for its quality and durability. Objective measures looking at passenger vehicles, such as J. D. Power surveys, demonstrated a downturn in reputation in this criteria in the late 1990s and early 2000s. By mid-2005, Mercedes temporarily returned to the industry average for initial quality, a measure of problems after the first 90 days of ownership, according to J.D. Power. In J.D. Power's Initial Quality Study for the first quarter of 2007, Mercedes showed dramatic improvement by climbing from 25th to 5th place, surpassing quality leader Toyota, and earning several awards for its models.
For 2008, Mercedes-Benz's initial quality rating improved by yet another mark, to fourth place. On top of this accolade, it also received the Platinum Plant Quality Award for its Mercedes’ Sindelfingen, Germany assembly plant. As of April 2011, Consumer Reports of the United States has changed their reliability ratings for several Mercedes-Benz vehicles ranking them "the least reliable vehicles in three categories. Six of its 13 models were below average, and the GLK SUV was far below average this year.
