The no sound problem is the audio amplifier. The audio amp has a heatsoak issue in some circuitry which causes it to miss the wakeup handhake. If it doesn't respond within a certain time parameter, then you get no sound. I brought it in and had the software update, but after further testing the tech made the call for a new audio amplifer. The software update I belive gives more time for the amp to respond, but if the amp is defective then you can still get no audio at times. After the update it went 12 days before no sound. After doing some research, apparently the fix is a new (updated) audio amplifer, the circuitry internally has been improved to better deal with heat. I had to wait 2 1/2 weeks because at the time, it was on backorder with no eta. Well the amp came in earlier this week. I had the amp and programming work done today. After picking it up I stopped at a few places, and whenever I started my truck, the audio was on instantly, so whatever they did it appears to work because it's never had sound that quickly......Hope this helps
I have the 18" black mutilspoke wheels that came with my truck. I like them as they are very subdued and look good with the 295/70's
I am sure that the next set of wheels I get will be some after market all black wheels. Or maybe some AT4X wheels.
Interesting question which you partly answered in the word 'potentially'. I think that is going to be a 'point of reference' inquiry. What are the touchstones?
This will sound petty but it is the main source of end fighting in threads on this topic. Define a motors "Life". Think about the various arguments that have been entertained on these pages in that very argument.
I can only speak from my viewpoint. Engine "Life" in my world is defined by power cylinder integrity. For the majority of engines it is the bore/ring interface that quits first. Loss of seal. Oil consumption and loss of power. Most Pro motor builders would agree and there is a good deal of information on using "Leak Down" as a primary indicator of bore integrity. At home a compression test is more the thing. If we can agree on that then I think CC Jensen has done its homework and I'd find it valid.
Now by my own definition, Dizzy, wife's Ecotec 2.4 I-4 has been dead since about 80K miles. And yet we have logged over 200K miles more on it. "Life" and "Usefulness" are therefore independent.
I know a mature fella right now who has just hit 300K on a Mitsubishi 3A92 NA MPFI motor and has done compression test every 100K. It was 205 psi after break in and is now about 195 and still even. He uses shelf oil but good filters and adheres to a 3K mile OCI. He even do UOA's on each of them for the first 50K.
I also know a fleet mechanic with that same motor that gets 300 to 500 K out of them but the are oil using, wristpin sloppy, skirt slapping motors. He ran one with a piston pin so loose the piston was bouncing off the cylinder head for about 20K miles before he called TOD. Both of them claim success.
Shouldn't the fault be saved and able to be pulled with a reader? Otherwise, maybe start taking pictures of it which will have a date and time stamp, so you can build your case.
