First out, I haven't been made aware of any widespread issues with the I-5 used in the Colorado/H3. That doesn't mean there isn't the possibility of isolated issues. I do know that we have not replaced a single cylinder head...yet. When GM requests that an assembly replaced under warranty be returned to the WPC (Warrany Parts Center) it is to determine the root cause of failure and to determine if replacement was warranted. This take time. If there is an issue, and it is widespread, then it becomes a recall or campaign to repair a defect. If it is an isolated event, usually regionalized, it goes out as a TSB (Technical Service Bulletin) and IF the issue is brought as a complaint by the consumer AND the vehicle falls under the parameters of the TSB, the repair is performed.
That is how it works.
Now, as far as replacement of the cylinder head being warranted, I believe that it is standard practice to tear it down and send it out for magnafluxing and surface flatness by a qulaified machine shop. If the valves were burned due to a lean condition, GM would pay to have the damaged valves replaced, no question. If the head is warped beyond specification, it would be replaced, no question. But if you read your new vehicle warranty, it clearly states redundantly, that GM will repair OR replace at their discretion. In other words, what would most benefit them, make the consumer happy, and cost them the least.
My guess is they suspect a calibration problem, are working on a temporary field fix to get by on, and will come out with a TSB shortly containing a recalibration. </div></BLOCKQUOTE>
I totally agree. That sounds in line with what they are telling me. They said they were sending the entire assembled part back for evaluation.
The only reason I even brought up the recall is that my dealer said he already had 2 with this problem and when I called back he had two more.
As soon as I posted anything about this here everybody immediately starts calling me a liar, future prius owner and every other kind of thing. No one wanted to even possibly think that I was telling the truth.
The only reason I have followed this as long as I have is to see all of those people realize their wrong.
It's funny that I have given VIN numbers dealer info and no one still wants to admit that I've been telling the truth.
I stick with my original statements.
