starting to have IPC problems with the reset buttons not working all the time. sometimes yes and sometimes no. got this crazy code QC424111 and nobody knows for sure what it is. have been doing some reading on this problem. looks like most get a salvage gauge panel. rather not go that route. would like to find someone who can repair these IPS's. this seems to be a problem with the c5's. have talked to a few repair shops that need to see the part number to know for sure if it's repairable which means a crap shoot to me. a few owners said the new button panel did not correct the problem. anybody know what a fix is or what you did for a fix? thanks Denny
