#9 of 11 Reduction in power when climbing a steep hill by ceric Oct 14, 2008 (10:22 pm)
Thamks to Karthikcx9. I did a quick type-up. Please forgive the typos.. Your dealer can find the whole bulletin from their computer.   DTC: diagnostic test code ATX: automatic transmission TCM: temperature control module ATF: automatic transmission fluid   ------------------------------------------   REUCTION IN POWER WHEN CLIMBING A STEEP HILL Bulletin No. 05-008/08 Issued: 05/23/2008 Applicable: 2007-2008 CX9 with VINs lower than JM3 TB**** ** 159178 (produced before May 1, 2008)   Description: Some customer may complain that the vehicle power is reduced suddenly when climbing a steep hill.

Replying to: nhokt (Oct 14, 2008 5:58 pm) I am glad to hear that they fixed the problem on vehicles ater 5/1/08. They bought my CX-9 back prior to that because it would not negotiate the road I drive to get to my home. Yes it only quits for a few minutes then you can restart it, but in that few minutes in snow or bad weather, it is dangerous.
