Default Excessive Quote?

Hi Guys

Wondering if you guys could help me as Im not a car expert

I have a 2017 Grant Sport Collectors Edition. Ive had it since 2017 and barely put 20K miles on it.
I took it for a service few months ago (Official Chevrolet Dealership) and only recently noticed oil leaking. I thought maybe they didnt put something back on last time they had it so i took it back to them (Same Official Chevrolet Dealership)

After a few days I get the following needs to be fixed, the oil cooler and flywheel needs to be replaced.(mind you this car has only 20K miles on it and take really good care of it)

After looking on these forums it seems these arent uncommon problems with the C7s which sux on a $90,000 car but not much i can do about that now.

The parts themselves are about 30% over priced of what I could buy them online for but the FlyWheel seems like alot of labor doesn't it? 26 hours?
Im not car expert but something seems off that a car thats barely been driven required $10,000 worth of work?



Is this quote excessive?

Im looking in Las Vegas for other corvette mechanics to also get comparison quotes.

Thanks in advance

I searched on these forums and its pretty common issue on these. I also asked them I want the specific reason WHY it needed to be replaced and they sent the below document

I take it to Chevy because they have official Corvette technicians and access to Chevrolet etc. Also limited corvette specialists in my area from what I see.

I did ask them specifically why does this part need to be completely replaced and they sent me the official document about it. See below

Were you experiencing this rattle ??…being a “Corvette Specialist” is a bunch of hogwash …a few years ago I had my Central Air replaced down here in Florida and one of the young AC Techs had been the “Corvette Specialist” at the local dealership here in town before he left…I was asking him a few questions just to see how much he knew and he didn’t know ANYTHING…they had only asked him to be the Corvette Specialist and they didn’t send him to any Corvette specific schools or any type of training…any good auto Tech with Service Info and some smarts can fix any Corvette or any car for that matter…the Corvette is not some magical kind of car that only a select group of mechanics can repair…BTW, there are a few TSB’s concerning rattles.

Did you complain about a rattle? If not, this is a ripoff pure and simple. Even if you did complain about a rattle, the hours for the repair as C5Diag mentions are beyond excessive.

Run from this dealer as fast as you can.

Based on their "quote", it wouldn't surprise me if they failed to tighten the oil filter completely and/or when they removed the old oil filter the rubber seal was left in place and they screwed the new filter right over the top of it.

It's very Very Very rare for the oil cooler to fail. The ones I've seen leak are from a debris hit. An oil leak in that area (assuming it's not the oil filter as I mentioned above)....is usually the gasket that fits between the oil cooler and the block. The gasket costs about $10 for the OEM part....and it takes less than an hour to change.

Edit....I see they also have the torque tube listed...aka the Driveline Support....listed for $2600 which is 10% more than MSRP! This dealership is fk'ing criminal.

Yeah as soon as I read it i asked how are you charging 26 hours when the doc specifically says it should take 11
He said "Thats warranty hours" So Im not sure if because its warranty they only get half of the hours they normally would as opposed to paying them 50% of their hourly rate.

Im trying to see what other corvette specialists would say just arent that many in Vegas. Unless anyone can recommend any would be appreciated.

Yeah I did ask him that because I saw the hours where only 11 compared to 26. When I asked him about that he said that's because that's "warranty hours". I've worked in IT service departments before and warranty jobs are always much less than your regular service rate so I just assumed that it's possible that rather than charging them 50% of their regular service rate they just quoted half the hours. Either that or they are completely ripping me off.

Yes, warranty hours are less than the normal book rates and if it’s warranty work you won’t be paying for it anyway…so did you have a rattle ??

I'd bet its a loose oil cooler.

This is and was an issue for a period of time.

I'd first check the bolts on the cooler for proper torque.

If the cooler is leaking you should be able to see it.

if the torque is correct and the cooler is leaking, replace the gasket.

NOTE:
Listen to what C5 Diag says and you'll be miles ahead. He has real time experience and is correct 99.9% of the time.

I'd 'like' to think I'm the other 0.1% of the time. Follow my advice at your own risk!

Yeah when just sitting on idle I did notice a faint noise/rattle like something was loose that would seems to stop if I rev'd the throttle even slightly. I'd actually forgot to even ask them about it but they came back with that flex wheel issue which I guess would make sense.

Will try get other quotes and see what they say.

Thanks for everyone's suggestions guys much appreciated

Oh mate thanks so much! I took the car home and was struggling to find someone to take it to. I'm out of country for a few weeks but will definitely call them when I get back and/or message you as well.

Whatever you confirm the diagnosis, no shop is going to perform a flywheel replacement for 11 hours. The bulletin time indicates what GM will pay, not what a shop is going to accept from anyone other than GM. By all means shop around just don’t expect to find 11 hours as it’s not reasonable.

Find yourself another dealer and get a diagnosis. Could save you a bunch of $$$$.
