# Service bulletin A911263 2021151\- A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned. - Type: Service bulletin - NHTSA id: 10122771 - Published by NHTSA: 2017\-11\-08 - Manufacturer's number: A911263 2021151\- - Manufacturer's date: 2012\-10\-04 - NHTSA component: ELECTRICAL SYSTEM; EQUIPMENT:APPLIANCE:AIR CONDITIONER ## NHTSA's summary Supersedes Technical Service Bulletin Group 91 number 11 ? 83 dated April 15, 2011. The customer may report that the illumination of the dash insert, the air conditioning control panel or the inside light flickers when briefly pressing the accelerator in P or N or when shifting down while driving downhill. Only vehicles with PR number 8GH may be affected. When high electricity consumers are switched off and 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, and the lights mentioned above may briefly flicker. This characteristic is caused by the alternator design and is a normal condition of the vehicle. ## The document - [NHTSA's copy of the document (PDF)](https://static.nhtsa.gov/odi/tsbs/2012/MC-10122771-9999.pdf) - [If that address does not open, try this one](https://static.nhtsa.gov/odi/tsbs/2012/MC-10122771-0001.pdf) The document is the manufacturer's.
