Why are there sometimes considerable differences in reliability between “related” or “twin” models?
Some variants of similar vehicles have different reliability results in our survey. Although you might expect that related vehicles, or “twin” models, would have very similar reliability histories, there are a number of factors that can lead owners to have different reliability experiences with these models. Some differences can be attributed to different equipment, such as different transmissions, suspension tuning, or power equipment. Some related models may be manufactured in different plants. While their designs might be quite similar, by being built in separate facilities they may be subject to different manufacturing processes, such as differences in quality control. Some model variants that share the same design but have different equipment level or body style can lead to differences in reliability. For example, the V6 version of the Chrysler Sebring has below average predicted reliability, but the 4-cylinder version had average reliability. The V6 offered more standard equipmen

While their designs might be quite similar, by being built in separate facilities they may be subject to different manufacturing processes, such as differences in quality control. Some related models that share the same powertrain but have other differences may have different reliability. For example, the redesigned for 2010 Chevrolet Equinox SUV had average predicted reliability, but its near twin, the new GMC Terrain, had below average reliability. The Terrain had slightly more electrical, audio, and paint
