Will GM dealers enter repairs in carfax??

[91RS]

Thanks for the info...too bad they don't enter more. What is Carfax good for then? Accident reports to DMV or local authorities?

Yes. That’s the biggest reason to use Carfax. I’ll never buy a vehicle that has been in an accident again. Carfax is a good place to start but it always pays to get a PPI in my opinion.

Good topic.
I wondered of my original engine had afm failure at one point, and had the camshaft replaced.

Reason was a weird cam bearing failure that i blamed on engine sludge and my attempt to clean the engine.
Tiny little filter bypassed and wiped out the first thing in the oil path, the rear cam bearing...

But some of that doesn't make sense since i would expect trash in the rear main as well.

Other thought was a damaged bearing due to a rushed or sloppy camshaft replacement.

My lifters and camshaft looked really good for having nearly 180k on it...

Nothing on the carfax about any sort of internal engine work...

But the prior owners did buy it from a dealership.
Possible they took it on trade with the taps.
Fixed it for cheap and then sold it off.

The people i got it from,
They had it for less than a year.
When i went to look at it, it was parked and the registration was expired...

I suspect they realized some serious damage and opted to just replace the tahoe with the xl gmc that was currently in use.

I might try the dealership where they bought it from, it's very close to me...

Not that it matters at this point, but i am curious.

I used the CarFax for my vehicle to determine which businesses did work to it. Then they were each contacted and they kindly sent me pdfs of the receipts for the work performed. I reckon it's not complete but it sure did answer some questions and provided a good maintenance history.

Now back to the Tahoe, does your husband have a Tech-2 or bi-directional scan tool? A cheap little code reader is not up to the task of properly diagnosing these problems. Do y'all live near Stockton? There's a guy on here with one.

His mechanic friend at work has the higher end Tech readers and nothing popped besides P0300. Husband also borrowed a midline one that still just shows the P0300. The problem is knowing how to use them properly. I think that we will try to buy a new or used one if this continues or for future fun haha

Husband and I are still chasing the elusive misfire, rough idle, P0300 & CEL (and now intermittent stabilitrac service light) on my 2007 Tahoe. He's going to either do some more troubleshooting himself (or his mechanic friend) to continue to try to chase it down. We have a list of potential "fixes." It's loooong

Since we bought it from a daughter of the deceased owner, was not able to ask questions about maintenance/repairs. Looking at how clean the interior and the engine was, I'd have to assume that he took good care of it.

Of course the 1st thought is I'm having the dreaded lifter failure, but we're not getting any sounds/power issues that indicate a lifter failure.

I would love to know what, if anything, was done to it before I bought it (including the known issues that were put out in bulletins that we all now know about).

If this vehicle was serviced at a GM dealership, would any of those fixes (if they were done) likely show up on a carfax report? Maybe I can at least start with some sort of knowledge of what has been done before I purchased it without having to have anyone tear everything apart to find the cause of this dang misfire(s)? Husband hasn't worked on this vehicle before and he thought he could just pop off the spark plugs and wires and change them around to check to see if any were bad haha nope! Doesn't have the fancy boot remover.

Here you go Caligirl

Last one

Woohoo, thanks! At least I can confirm regular maintenance thru 2014, but sadly no info shown about replacements/preventative fixes for those reported known issues. I suspect that during the 2014-2021 period before we bought it (only another 20000 miles) if pattern holds, probably started taking it to a dealership that didn't report. But definitely shows good history of maintenance. And daughter took it in at 86k for a 90k check up/maintenance at dealer and spent $1500 plus, including all new iridium plugs and wires etc. We now have 94k on it, so thinking this is a new problem. First accident was probably what caused the crease on bumper. That last accident listed was after we owned it for about 6 months and while it was parked in a parking lot, someone backed into it grrrrr. But the body shop fixed it right up and looks brand spanking new. At least we know oil kept clean, which sounds like for this engine is paramount to good engine health

Thanks Myfirstz71

There is something called "Failure Record" that the computer takes a snapshot of what was going on when the code first appeared. A bi-directional scan tool can retrieve this. These tools can also graph and record different things and in this case, it can also test the injectors, coils and de-ac lifters which is what I would do.

We cannot effectively work on these vehicles without them and the shop manual.

Performance Chevrolet did a lot of work on that truck, that's who I'd call and ask for the service records. Often times descriptions like "checked computer" are code for major repairs.

So "checked computer" wouldn't be listed on this report, too? Such a mess trying to track down history. Seems like the newer vehicles are much more of a risk to buy without complete history than older ones. Yeah I know, I know the newer ones have better performance and better gas mileage yada yada, but the old ones just seem to just be like the Energizer Bunny!

I meant that as an example of how to "read between the lines". Even when poorly maintained, these trucks last a lot longer than their ancestors. When I was a young man, a car or truck was considered wore out at 80-100K miles.
