There is an unpleasant, musty odor coming from the heating and ventilation system. The odor usually occurs when the vehicle has been sitting unused for five hours or more. The odor usually occurs within 20 to 60 seconds after the vehicle is started. Condensation, which is a normal condition in all A/C systems, can cause a musty odor. If the odor is noticeable in the vehicle when the engine is not turned on, the cause may be mold and mildew in the passenger compartment, and not be related to the A/C system. All other possible sources of the odor must be investigated before this bulletin can be performed.
A901451 2021151-2017-12-05. Service bulletin. EQUIPMENT:APPLIANCE:AIR CONDITIONER. Supersedes Technical Service Bulletin Group 91 number 12-63 dated October 4, 2012.

The condition occurs when the accelerator is pressed while the vehicle is in P or N, or when the vehicle is shifted down when moving downhill. Only vehicles with PR number 8GH may be affected. When high electricity consumers are switched off when the battery is fully charged, the energy generated by the alternator is sometimes too great for the power system to absorb. This may lead to briefly-increased voltage, causing the lights to flicker.
