Used car yesterday and release worked fine left of steering wheel, but tried today...no go...nothing...no sound etc. Tried fob....nothing....no sound etc. Used rubber button above license plate....worked. Researched...valet mode? Nope...went in and activated then deactivated...nothing. Not a vert so not part of recall etc. Tried physical key to right of button by license plate. Worked....supposed to reset valet....no go. All options failed...tried everything... Pulled out space heater and warmed up garage to defrost rear....nothing. Decided to check fuses. Pulled owners manual. Two fuses in rear fuse block associated with trunk release #26 and #31. Getting carpet up high enough to move load floor plastic cover....brutal. Finally got to fuses. Pulled each...a 10A and a 15A....nothing....in tact. Put back in...put load floor in...carpet.....closed hatch. Pressed fob....BINGO!!! Worked!!! Must have reset module!!! Good to know
