SummaryThe instrument cluster displays a fuel range of zero miles before the fuel tank is completely empty. Upon refueling at a displayed fuel range of zero miles, the fuel tank accepts fewer gallons than what is shown in the owner? s manual capacity chart. To ensure mobility, a small amount of fuel is still available when a fuel range of zero miles is initially displayed. Additionally, the fuel range is calculated based on the most recent driving style. Therefore, the actual amount of fuel remaining may vary when a fuel range of zero is initially displayed.

SummarySupersedes Technical Service Bulletin Group 94 number 11-52 dated October 11, 2011. Condensation is visible on the inside of the headlight, taillight, fog light, side marker light, front turn signal, daytime running lights, or third brake light lens. Damp air settles on the inside of a cold lens, which creates condensation. The headlight circulation system allows air from the outside to flow through the headlights. This open waterprotected ventilation system (needed for pressure compensation) creates different climate zones in the headlight: very warm areas, where the lens is warmed up by the light, and relatively cool areas, where the lens is cooled own by the air flow. Considerable differences in humidity and temperature between the inside and the outside of the headlights, even while driving, can lead to condensation. This is especially true in cold and wet weather, but it can also happen after a car wash, after steam cleaning the engine or the front end, with overnight temperature changes, etc. This phenomenon is more visible on lenses made of clear glass than on lenses with patterns. The moisture does not affect the headlight function (light performance) and does not lead to corrosion or other damage to headlight parts.

SummarySupersedes Technical Service Bulletin Group 27 number 12-14 dated October 12, 2012. Complaints are reported by the customer regarding electrical features and functions in the vehicle. One or more warning lights on in cluster. The DIS or other displays in cluster are blank. MMI does not function. Windows do not function. LED indicators in various buttons inside the vehicle do not light up. The voltage regulator on the alternator can sporadically fail causing the electrical system to experience too high of voltage. As a result, the affected vehicle electronic components go in to high voltage protection and deactivate sensitive displays and indicators to prevent electrical damage. When an over voltage condition occurs the vehicle electronics and alternator are protected, thus there is no need to replace the entire alternator assembly.
