DETROIT – The GM Hummer brand announced on March 5 that it is enhancing the warranty on all of its 2006-model year vehicles to four years or 50,000 miles. Hummer products previously were covered by GM's standard three-year/36,000-mile warranty plan. The move to a four-year/50,000-mile plan is consistent with that of many of the industry's top premium brands, including Cadillac.
