2023 Stingray with 47,000 miles. Bought new. I bought Chevrolet Protection Plan, CPP, from Dennis as the factory warrenty was running out.

Car is sending codes because of problem starting. Sometimes just stumbles, sometimes choughs badly and dies, sometimes cranks extra long before starting. It is doing more often as time goes on.

CPP approved replacing the fuel module, twice. No fix.

Now the inspector approved that it has a fuel pump problem. I think they will replace fuel pump. $3,400 job.

I was told that if the dealership does investagative work and if the test comes back negative that the car owner owes for the testing. Hmmmm. 5 hrous to test the car for a problem you know it has because you have experienced several time. Test comes back negative. I need to pay for testing. So told to me from my service manager at GM dealer.

What have you experinced ?

 

It is stated in the warranty that if the problem is diagnosed as a non-warrantable item then the customer if responsible for the diagnostic charges. And basically that means if the diagnostics doesn't come to a conclusion that it isn't a covered under warranty.

In your case if the fuel pump fixes the problem then the fix should ultimately be covered under warranty but you may have to pay for the fix and then ask for reimbursement.

The problem is if you have to pay for the diagnostic charges. I'd ask for roof that the dealer correctly followed each step in the diagnostic tree and that it didn't correctly identify the problem.

 

Your story says it's sending codes, how is this not a warranty thing?

 

I don't know what the OP is talking about because I'm still stuck on "2026 Stingray with 47,000 miles."

 

Yup, 47K miles on a car that is probably not been on the road for a year is a LOT!!!
Now, I use my truck for work, drive over the road long distance, and put about 75K to 80K miles a year on it, but it ain't a Corvette!

Anyway, yes, diagnostic fees are on the owner if they can't find a problem that falls under warranty.
But, yes, would seem that if it is throwing codes then some sort of warrantable issue should exist.

 

It’s not a 2026. He said the original warranty was running out when he got the extended warranty.

 

I interpreted that to mean it was expiring because of miles.....nearing 36k miles...rather than the three years. That alone would not rule out a 2026 would it?

But he would have had to pay the higher price due to having more then 24k on the car at the time of purchased of the protection plan. My understanding is that the mileage break points for a price hike are 12k miles and 24k miles.

 

My bad. 2023.

 

This sounds like a bit of a tricky situation. Multiple codes may point to different diagnostic procedures - and sometimes there are instructions about which to perform first when there are multiple DTC. Reading through them, I have difficulty sorting out the instructions - I would assume a tech does too. But diagnosis is typically a process of "ruling out" the simpler cheaper causes first. So it might be expected that the tech will go through a procedure which reveals nothing or has not conclusion. My opinion is those should count as part of the procedure that eventually leads to the covered issue, because you don't get to the covered issue until you go through all the steps (which is what you are saying, I think). But there are cases where the diagnostic steps just fail...and under the factory warranty the dealer contacts GM for help when that happens. I would still consider completing the diagnostics prescribed by the procedures as a necessary step toward finding the issue because the process is one of ruling out causes until you find the cause. But how does the protection plan work in the cases where GM has to be contacted because the procedures have been exhausted. Looks like from OPs experience they call the CPPP administrator rather then GM - so not sure what technical guidance the dealer gets.

Regardless....this "I was told that if the dealership does investagative work and if the test comes back negative that the car owner owes for the testing. Hmmmm. 5 hrous to test the car for a problem you know it has because you have experienced several time. Test comes back negative. I need to pay for testing." is NOT what the contract says. What is says is that its not covered if the diagnosis indicates a mechanical break down that is not covered then the diagnosis is not covered. But in this case, the OP case, that is not what is happening. Rather the procedure so far has either indicated a covered item, or has ruled out items in the path toward finding the issue. But its pretty squirrely.

"Diagnostics Coverage (included with the Platinum, Silver and
Powertrain Coverage Plans)
We will pay for reasonable, necessary and customary diagnostic
charges incurred in conjunction with a covered repair, not to exceed
the labor time listed in a nationally recognized parts and labor guide
such as Mitchell or Alldata. DIAGNOSTIC/TEARDOWN TIME
WILL NOT BE PAID IF THE DIAGNOSIS IDENTIFIES A
MECHANICAL BREAKDOWN THAT IS NOT COVERED UNDER
THIS AGREEMENT OR FOR THOSE CONDITIONS WHERE THE
PROPER REPAIR IS READILY APPARENT TO THE NORMAL
SENSES OF SIGHT, TOUCH, SMELL AND/ OR SOUND."

 

I agree. It has sent a code at least 8 times in the last 12 months.

Engine code indicator light on the dash leaves after a certain number of starts. Code might still be in the car system. I usually bring it to any GM dealer and have the code verified and a print out. Even when out of town. More verification of the problem the better my case.

 

The problem with the code the car is sending is that it is so generic. It could be many different things. What good is a code or system like that ? I believe it sends the same code every time. Of couse they want the car to act up when I bring it in. Nope. It could happen today and then not happen again for weeks. Yes, they are following the diagnostic tree. Dealer says the warrenty company is just being cheap and does not want to spend the $3,400.

 

The key is that to be covered, it needs to an "covered mechanical breakdown." There are issues that will set a DTC that but not result from a covered mechanical breakdown. For example, "ANY MECHANICAL BREAKDOWN CAUSED BY
CONTAMINATION, OVERHEATING, LACK OF COOLANT OR
LUBRICANTS, LACK OF OIL VISCOSITY..."
is not covered, but an overheat condition may set a DTC.

Note also that the coverage is specifically for "mechanical breakdowns". Its not at all clear that software issue are covered. What is covered is software updates if they are necessary because of replacement of a covered component. The CPPP will covered "non-covered" components when necessary as part of repairing a covered component, or when caused by failure of the covered component. But if an issue is resolved simply by updating software in an existing module (which has been reported), then it may not be covered by the CPPP.

"If a Covered Part causes damage
to a non-covered part or component, the repair or replacement
costs associated with the non-covered part or component are
covered under the Platinum Plan."

 

Well, ok then, that rules out the 2026!

 

Some years back, a friend had an intermittent issue with fuel starvation. They practically tore the car apart to find the issue. Ya know those little foil looking seals that are under the cap on a bottle of fuel stabilizer...that you peel off to open the bottle. One of those made its way into his gas tank and was apparently intermittently causing a fuel flow issue. There are so many places where a fuel flow issue can arise.

What is the code, by the way?

 

May wanna edit the OP because lots of folks dont read replies only the OP. Will reduce replies that arent helpful perhaps.

 

The very first words of his post says "2026 Stingray with 47,000 miles"

 

His profile says he has a '22.

Interesting. They CPPP already paid/replaced the fuel module at a cost of about $750 each time. I still have the same problems with how the car starts and runs after both module replacements.

 

The best I can understand what ser. manage gave me was a DTC P129F, on the top of the page. It also says, "Fuel Pump Power Control Module Fuel Pump Speed Signal Incorrect."

Managers hand writen note. He wrote, "During Diagnosis found RPM between fuel pump & contro module not within 200 RPM of each other. Diagnosis before virtual inspection from extended warranty."
