I know we didn’t buy these cars for gas mileage, but it is amazing how good they are in fuel, of the three vehicles I own for family driving this one is the best for fuel economy when I thought it would be the worst.
I've got a C 8 that is coming up on 3 years with about 15,000 km on it.
I also have a extended warranty & the essential care maintenance plan that I bought.
The car's had it's oil & filter done every year, I rotated the tires side to side , & had the DTC filter replaced as per GM last...
I got the car back about a week later, they found a nut rolling around inside the rear by the drivers B pillar area. They did show me the nut, looks like a 12 mm socket would fit it with a washer attached. It looks like it’s never been installed.
I also needed a front bumper repair so it fit...
The cars at the dealership now, I was just wondering if anyone had seen anything like this before.
It’s a 2023 & has lots of warranty left, it’s not my problem , but I’m not sure they know what tree to bark up when trying to find it.
I guess anything is possible, it does sound like it's coming from somewhere inside the car.
Since I've never heard what a small stone rolling around under the car between the lower splash shields sounds like I don't know if that is it.
If this is the problem how could a person stop small stones...
My car is a 2023 C8 Corvette Coupe, when turning corners, hard braking or rapid starts you can hear what sounds like a nut ( or bolt ) rolling around on the left side of the car.
I have removed the roof panel & it made no difference.
I've tried opening and closing the left door part way...
Yes if the car is under warranty they will pay for the readjustment and paint repair. There is a product service bulletin on this and shows the dealer how to fix it. The product service bulletin is in a previous post.
