Hi Daryl - When you say, "already used a new grand cherokee up", what does that mean??
The reference to "going away from so many electronics" is ominous. Does that reference your poor experience with the Jeep?
There are virtually no vehicles built in the last 20 years that don't have serious amounts of electronics in them.
It certainly is advantageous to have minimal electronics, but that means having an extremely basic and not particularly efficient vehicle, too.
Electronics are the reason why todays vehicles perform so
well (when they are running properly) - but many electronic components in numerous vehicles, are poorly sited, poorly protected, and have harnesses with insufficient protection from road
debris, water, and dust.
In the case of many Jeeps, poor wiring assembly, or general assembly faults is often the reason for their poor record with electronic problems.
The other electronic sources of problems are excessive complexity and faulty programming.
Problems in these areas can be extremely hard to track down.
A nephew owns and runs around 40 Cat machines. He bought a new Cat motor grader several years ago, costing $750,000.
These earthmoving machines are also becoming complex with no less than 9 ECU's on the Cat grader.
The grader ran fine for a couple of weeks, then it wouldn't go over 9kmh! It's supposed to do 40kmh.
After numerous visits by Cat servicemen, they couldn't find the problem!
So, the Cat dealer flew in a high-level Cat technician from the USA!
The American technician spent some hours on the repair before he found a software programming fault that meant some of the ECU's were not communicating with each other!
He re-programmed the software and the fault went. That was a pretty expensive warranty repair for Cat!
The grader is still performing
well, several years and many thousands of hours later.
Cheers, Ron.
