Couldn't a bad/blown head gasket cause these problems?

 

^^That's why a prior poster said to check for coolant in the oil; assume that the service tech did this but not a certainty. The deformed rad overflow may be an issue. OP, take a look at post #86 pic and look at yours. It'll be interesting to read what yours looks like.

I find this mildly amusing as my truck cost as much as my Corvette. You can find trucks and SUVs that cost as much as a Cadillac at your Chevy dealer. What makes the Cadillac or Corvette so special? I'd like to be treated right whether I bring my Corvette or Cruz in for service.

Here's a snapshot of my small, local dealer's inventory listed by price, high to low. There's a Corvette right at the top at $73K and a Suburban right behind at $70K.

 

If I were troubleshooting this issue on my dollar, I'd start by replacing the radiator cap and removing and testing the thermostat. You could just change the thermostat, but testing would verify the problem. I'd like to do the same thing to the radiator cap, but they are harder to test at home.

If the problem continued I'd take a hard look at the water pump to make sure it's moving water. A blown head gasket would be pretty far down my list and you can usually tell if there is a problem by looking at the dipstick or the coolant in the radiator. If there was milky oil or oily coolant, a compression test would pinpoint the head gasket.

You have to work through the potential causes of overheating one at a time. I wouldn't expect a dealer to shotgun replace every potential part that could cause the problem.

 

I definitely would not worry if I were you. Every single forum has people complaining about issues. When I bought my BMW, I read all of the forums before hand and they scared me so much that I almost cancelled my order, turned out to be an amazing car. Had the same issue with Infiniti on the forums, turned out to be the most reliable car I ever owned. You have to remember that a very few % of the owners actually experience problems. Nobody goes on the forms to say how good their car is in heat or in traffic. Mine has been fantastic so far, hope that does not change. Regardless this car is so amazing, the joy of driving it everyday will definitely outweigh any tiny problem you might have. Although overheating is definitely not a small problem, I wouldn't waste any time worrying until it (if) happens to you.

You will never buy another car or take another prescription if you read car forums/listen to commercials.

A8? Z51?

 

You are correct, I have never had any problems with the 5 different series of Corvettes I have owned before the internet existed. Makes me laugh when I actually think about it - but nothing is going to stop me from getting my 2016 C-7 unless I die, or GM folds. Thanks for the common sense supportive post!

 

Bugs are worked out! Or there was never was a bug. I sat in 96 degree's for 30 minutes still at 200 with my 2014 as well as my 2015 Z06 no issues with heat. But I'm not beating mine around a track in 95 degree weather.
Not my idea of a good time.
Your reading about a FEW WITH TROUBLE Remember there are 50 thousand of them on the road.

 

Yea, I get it given numbers and percentages, but I just really wish GM would take the same view on quality and reliability as Lexus does. They sell the most reliable and some of the most luxurious autos in the world, and have customer service rated #1 year after year. GM could be the best in the world if they chose to be, yet they just will not pull that trigger and make that commitment - all I am saying is I wish they would - it would be nice to have a USA automaker recognized as the best in the world!

 

I posted a thread about intermittent overheating. It turned out that I needed a new water pump.

 

No word from GM Service. The car is a A8 non Z51. Hopefully they will find out what's wrong with it. The car has not been abused and stays in the"E" mode 90% of the time.

 

That has ALWAYS been a problem with GM. They treat customers the same at the dealership whether you buy a $15,000 Chevy Spark or a $100,000 Corvette Z06.

There is no protocol built into their dealership network that calls for a "red carpet" treatment for the Corvette owners. There SHOULD BE but sadly there isn't. With that being said, SOME dealers take it upon themselves to put out a red carpet treatment for the Vette owners. That should be applauded but they are the very few minority that do treat Vette customers with more care. The majority of Chevy dealers look at you as the Chevy Spark customer and treat you and your car the same way.

In my 30 years of driving and owning numerous makes and models, the best treatment I ever had was at a Toyota & Mazda dealership and the worst treatment I ever had was at a Chevy and Oldsmobile dealership. That's just my experience, yours may differ, but if you read the forums plenty of Vette owners have been poorly treated at their Chevy dealers even though they bought a $60k+ dollar car.

It's like the hospitality industry. Hilton is the one best hotel franchises in the world because they have major QC inspections and high standards. On the other hand chains like Wyndham leave a lot to be desired. Find me a dirty and horribly run Hampton Inn Hotel. You won't be able to find one. Now find me a dirty and horribly run Days Inn or Super 8. There are plenty out there. Hilton penalizes the franchise owners if they fail QC inspections which are done on a monthly basis. It keeps the hotels in top shape and customer service has to be #1 or the ownership group gets fined.

 

I agree about the customer service though, that can definitely make or break an experience. Today I went to get my oil change and waited for close to 3 hours, no updates, no place to sit, had to go to the showroom floor an a.c, got the car back with some oil drops on the hood and all over my fender and headlight. Had to chase the manager around the service department because he would not stop to look me in the eyes and answer two simple questions I had, I had to run side by side with him just to get a one word answer. None of this is that big of a deal, and doesn't bother me too much but coming from a BMW dealership where they wash your car, get you coffee, have a nice waiting area, this was more like the New York Stock Exchange in the 90s, everyone is yelling, nobody knows what's going on. The crazy thing is, it's in a borough in NYC that's now the only dealership for 2.5 million residents.

 

I'm surprised, the water pump would have been way down the list on a new car. I have seen pumps leak at the drive shaft seal yet still pump away. Great it is fixed!

 

Hey ffamousamos,

It is great to hear that you love your C7, but I am so sorry to hear of the continued difficulty with this overheating concern. We definitely want you to have her back as soon as possible. Feel free to send us PM if this is something that you would like us to look into. Have a great day and we hope to hear from you soon.

Kind Regards,

GM is installing a secondary transmission cooler on all 2016 Z51's to eliminate any over heating issues. (which is the same as all Z06's).

 

Spoke with Service Rep today and was advised the tech was scheduled to look at my car today (They've had it since Monday). Anyways he told me they would look at the radiator cap and replace the fluid like they did last time, also said they would,pressure check the system. He also said they had a call into GM for advice on what to do next.
Why can't GM issue a TSB addressing this issue, it seems to be a common problem. Starting to get frustrated, if they try and give me the car back with a new radiator cap and fresh fluid I will be filing a complaint with GM.

 

I agree, all Corvette forum members should write letters to GM requesting they upgrade their customer service to be more like Lexus - who have the best service and treat you like a king whenever you enter a dealership or have service done on your car. It would be nice to have an American car company be known as the best when it comes to products, quality control, customer service and reliability. When you pay what you have to pay for a new Corvette, it should be exempt from problems !
