If you've read my posts re Toyota, you would know they disputed my assertion that the leaf springs were flat, then disallowed my reimbursement with a complete set of receipts because I didn't have the dealer diagnose it before replacement. That's the opposite of 'making things right'.
GM is balls-deep right now in 6.2l and 3.0l damage control.
Ford doesn't really have any hot issues that I can think of.
GM is balls deep in more issues than that.
Ford...well...brief list here:
* lifters/cams in the 7.3l
*3.5L cam phasers(the root cause of that debacle will make you laugh...hint...they cheaped out on springs that are about the size of bic click pen springs)
*f150s eat pinion bearings, 250/350 eat carrier bearings...guess which foreign country those started coming out of when they started becoming a common issue...starts with a "Ch" and ends with an "INA"
*6r80 lead frame failures in trans
*17+ Superduty eat ac comoressors
*5.0l oil consumption issues
*10r80 transmission CDF drum bushing walk/trans failures
*6f35 trans dropping like flies in the escape platform
There's more if I think about it....but thats all pretty big, expensive repairs.
Ford has at least typically had parts on back order or discontinued less than GM, but still can be significant delays on common service parts.
I see plenty of rusted out GM and Ford 1/2ton frames...never saw them step up and fix them for free...including any incidentsls needed due to rust for 13+years from production...say what you want about Toyota, but fact is they stand behind their products far more than any other manufacturer. Toyota has engine issues in the tundra...they recall and replace the engines.
Gm tries to bandaid the issue with different oil hoping to get them out of warranty before failure.
Your spring issue sounds to be the exception, not the norm.
