It would be very helpful to know if your replacement was an old part, or a new one with a new part number. I suspect there will be more than a few owners waiting to get theirs fixed also and want to know what GM has done to fix the problem.

 

I did not see the replacement unit. They told me they were replacing the complete radio unit which includes the screen.

 

Just curious if anyone else has had this issue...

Last night I get it my car start it and everything is fine, I get about 30 feet and my gauges go black for 5-10 seconds, the gauges "reboot" but the LCD stays off. 5 seconds later the LCD turns on, I'm in ECO mode but the gauge is in Sport mode and my normal preference is set to "link with drive mode"

I turn the car off and start it up again and it starts normal except for it's still in "Sport mode" so I go into the settings and it's selected to Sport, not linked.

This AM I go and start my car, once again in ECO, my gauge is in Sport mode, 10 seconds later it switches to ECO.

This is after 7000 miles, nothing new done to the car, hasn't visited the dealer in 4k miles. Odd!

 

Hell guys, first time posting, but have been a lurker for awhile, you guys have been a ton of help.

I bought my dad a vette, drove it from flint MI, to Virginia last week, He loves it! Now the bad part, with about 700 mile on the OD, I was driving it today when it developed a ticking/rattle noise in the engine bay. I pulled over and listened some more to it. No engine light, no indications anything was wrong other then the ticking that developed rapidly and was more pronounced at 2-3K RPM. Decided to had home. 1/2 mile later car dies on me. I was quickly able to pull into a drive way.
Dash is blank, doors don't work, engine will not start or turn over. All that works is the windows. info center, dash, EVERYTHING is Blank, not on. Had to have it towed. I could not even get the car out of park and into neutral, electrically the car is dead, except the windows.

I looked through this entire thread and have not seen anybody with this problem, has anybody heard of this? It is a HUGE disappointment and I am really worried.

I factory ordered the car vin 17056, dealership I had it towed to opens Monday at 7am est, hope they can diagnose quickly, until then any ideas guys?

They'll be able to plug into it and ascertain the issue then order the parts and fix it. Could be it just needs a new ECU. Keep us posted what you hear from the dealer, OK? If it's the ECU then like any computer it can be a bad part. It's not indicative of any common failure in the car. Keep the faith.

 

will do, will keep you guys posted....

 

This is common in C7 A6s and was explained in another thread by Snorman. Fuel is cut for 100ms between shifts, which enable quicker shifts. It does appears to be less noticable as miles build up, but is common and nothing to be worried about. If you look at the fast list you will see he turns in the 11s (1/4 mile) fully stock so I guess a little popping does not hurt.

 

We had our new C7 for 48 hours. (Purchased new in Michigan and shipped to Atlanta.)

It would not start, and a tow was offered but when a hook truck was sent, decided to attempt to start the car and drive to local dealership (Jim Ellis Chevrolet).

The plate that rests on battery was loose, but when pressed to make contact, the car would start and run long enough to get the car to the dealership.

Familiar Rear Axle Service light came on.

They have no Corvette tech on weekends.

They reported that work began on Monday but were unable to repair the car, ordered "a new fuse block"

Block arrived on Tuesday, and while the car started, this did not turn off the rear axle service code.

The differential has the "white dot" to indicate that it was likely made after the recall of last fall.

By Thursday, the Corvette tech felt that this was due to a module near the rear axle (communicated via a service counter worker) but we never knew which module. This part then was ordered.

Again, no return calls and we were told on Friday that the tech had not installed the replacement unit. Assured that we would be called before service closed on Friday. We were not called, and our calls to the service personnel went unanswered.

We were able to reach someone on Saturday. She sounded appalled at our plight, stated that she would call us back. Did not.

On Monday, at ~7:15 am service personnel called and said he was unable to reach or coordinate with Corvette tech, and we assumed that this replaced module did not solve the rear axle service light. Although we cannot be certain since data is not easily obtained.

Georgia's Lemon Law states that if a car requires service taking the car out of your possession for 30 days within 24 months, that you can make a claim. We are, as indicated, on Day 9+.

Obviously, we can move the car from Jim Ellis by trailer to (for example) Rick Hendrick or other Atlanta dealership although this is also going to consume additional time and will offer no guarantee of repair.

If anyone has valid/reliable ideas regarding the service code (beyond the reality that it can come on with the pos. battery cable disconnected for x-minutes), would appreciate specific information...part numbers etc. We do not feel after 9 days that the tech is able to find a solution.

The car had ~35+ miles when taken to Jim Ellis Chevrolet.

Thank you

 

OUCH! I would definitely have it taken to Hendrick. They are use to working on C7's and have tech to do it.

What is your VIN???

 

1G1YM2D79E5112485

Thank you for the reply.

 

Hi Brian,

We hate to hear that you're experiencing issues with your C7, please keep us all posted on your dealer visit. If you haven't already please PM us your VIN, dealer, and contact info. We'd be happy to look into this for you.

Just the dim cluster and hvac. Dealer has fixed and it's better. We'll see about the ac for sure when it gets hot in Colorado. I also had a flaw in the dash, a little divit, and the dealer replaced the entire dash pad, a two day job!

 

The car has been running great with no problems and have about 2800 miles on it. This weekend, a friend and I decided to take our M7 C7s out in the country and run some back roads with lots of turns. I decided to try the Track mode for the first time. We ran for about 15-20 mins, 3rd and 4th gear, speeds up to 60mph, RPMs no where near the red line. Stopped for a while and notice an oil leak under my car. Popped the hood and saw oil sprayed all over the right side of the engine. This photo shows the oil spill. The main spot is about 12 inches across. The other spots are from the oil dripping off different areas of the engine bay.



Got the car to a bay with a lift and jacked up and cleaned up as much oil as we could, but couldn't find the leak. When I revved the engine up and got the oil pressure above 40psi, it started leaking again, but couldn't pinpoint where it was coming from.

This morning I found this small puddle under the car.



The car is at dealer now and they are trying to find the leak. They think is is coming from the "air breather?" Anyone heard of this before? They are going to contact GM for information. Will keep you informed about what they find out.

 

Something's wrong. I can't see your pictures.

Added them as attachments. Does that help?

 

Yep. Should have kept them hid. That is ugly.

Just got a call from the dealer. GM Technical Assistance said they've had a lot of calls on this issue. The oil is overfilled at the factory and when put under high pressure (high RPMs), it blows out of the crank case and through the air filter. They did find the air filter full of oil. Supposedly, this only happens when the oil is overfilled and shouldn't be a problem again. We shall see. They also mentioned that it will happen if you run high RPMs before the proper break-in period. I told them the car has almost 2800 miles (well past the 1500 mile limit) and I made sure to follow the break-in instructions.

I did check the oil before heading out (run up to 175deg oil temp, shut down and check after 5-10 mins) and the level was at the top of the crosshatch mark. Seems to me that it wasn't overfilled and I haven't added any oil. By the time I got back home, the level was half way down the cross hatch. They're waiting for an air filter and have cleaned up the spilled oil. I should have it back tonight. I'm going to check it out at high RPMs and high oil pressure to see if it happens again.

 

Today I opened an official Customer Service Request for paint correction. The car, rec'd via motor freight 3/21, has EXTENSIVE orange peel on all panels. Not minor, MAJOR. I have officially requested GM's participation to correct this issue thru wet sanding or other means. Will keep everyone advised as to final resolution.

 

We want to sincerely thank Forum Members. As a result of expressed interest in our situation, we have been contacted and assistance offered.

We are awaiting notification that the problem(s) are resolved.

When resolution occurs, we shall post an update.

Thank you to all for reading and for the several that intervened on our behalf.

(Our intent was to trade this car with minimal miles toward an early Z06 but shall put a hold on our deposit pending this outcome.)

Hope to post again soon that we have our car back.

 

Well, Jim Ellis Chevrolet has the expertise and techs to do it too. Parts availability is beyond our control. Returning phone calls isn't, however. We are endeavoring to get this vexing problem fixed as soon as possible. I am monitoring the process and will stay on top of it. Mark Frost, General Manager.
