Did you read MT's statement? I think he's reading the oil temp gauge as the coolant because he stated "as you can see...... temp is fine"

Here reread it again:

At highway speeds and the typical light throttle openings seen during that kind of driving the oil temp usually runs about the same temp or a little lower than the coolant temp. The oil temp gauge shown in the picture doesn't provide very good resolution of the actual oil temp but it is over 200 degrees (the meaning of the lines is a little hard to determine because they aren't equivalent with the ones below 200). It seems reasonable to assume the oil temp is not anywhere near 250 but we really can't be sure. However, assuming the oil temp is in the low 200s the coolant temp should be somewhere close to that and likely not more than 10 degrees higher. That indicates there could be a sensor issue.

These issues aren't make-believe. When the issues are resolved in the 2017 model year, all of you that were vocal that the 2015-16 cars are perfect, might be too late to get your cars addressed.
While the very, very few cases of cars overheating on the street aren't make-believe, they are very rare and the result of isolated production issues that ALL cars have. I havent heard of any members claiming the car is "perfect", but it seems the majority of owners are really happy with their cars. Do some wish there were changes made, sure, just like I'm sure there are many Viper owners that have some gripes about their car. I don't track my car therefore I have zero issues with overheating but agree that for those that do, additional cooling MAY be necessary. Do I think GM NEEDS to "fix" something, no.

Sadly this car has had enough negativity surrounding it to deem it a "dog with fleas" as Michael Douglas said in Wall Street. My assumption is they rushed it to production without enough testing, maybe they will learn from this.

When was your Z06 built? Curious to try to determine if GM made some unpublicized running changes during the 2015 MY.

The percentage of threads here that deal with issues is way higher than it is on the Viper forums for sure, not certain about other manufacturers. That either means Corvette owners are just unhappy people who like to grumble or the car is less reliable and has more problems. GM needs to hear about this from customers, though as long as the C7 and the Z are selling the volume they are, I suspect nothing will change. No excuse for a 100K car that has the problems this one has.

I fully understand how to read the oil temp gauge and I don't have to assume the readings.

The lines from 100 to 200 are in 12.5 degree increments. From 200 to 320, the lines are in 15 degree increments.

Thus the oil temp gauge is showing 218-220 degrees, not 250 degrees as you assume.

Nah. They're just Jelly Trolls. The fantastic Nurburgring time and all the trouble free track days have proven that this is truly "The Most Track Capable Corvette ever". It is so good that they didn't bother to make any changes or improvements to the 2016 model save for a decal set for the C7R edition.

Well done Tadge and co. A truly remarkable rollout for your six figure Halo car. Bravo! (Slow Golf clap ensues)

yeah kinda like there is no issue with the C6Z06...its all trolls and internet hype

Mine was a second concensus car delivered mid-December.

So almost at the beginning of the production run. Great to hear it's performing well

How would you spin Andy Pilgrim driving a C7Z in a high heat/humidity day along with other former pro drivers and not having any overheat issues whatsoever?

Not overheating isn't a story.

Considering the joy I get driving out on the street, I feel guilty mentioning that it would be nice to not worry about temps at the track. Maybe it is simply asking too much of a road car.

We are currently looking for a car to develop a complete oil cooler system here in Houston Texas, its prime time hottest temps of the summer so shouldn't be an issue getting some great results.

If anyone knows someone please pm us or give us a ring at the shop.

I'll just leave this here...

A Friday afternoon, rush hour traffic on I4 in downtown Orlando, temps of 98-100*. Was in this for at least an hour, cruising on the highway at ~75 mph, temps are typically in the low-190's for coolant/oil.
Things like this definitely make me think that some of these cooling issues are isolated and on a car by car basis. Very strange.

Pretty obvious that something is wrong with that specific car.
If a C7Z can't survive traffic, it sure as hell wouldn't survive the pretty hard driving on track that several members on this forum do.

I'm new to the z06 so this is a scary issue for a person waiting for a car to be built. Will mine overheat or no? Looks like a roll of the dice, if it is a serious issue seems like a class action suit will come sooner or later to them if they don't fix.

Versus speculating what happed I asked a few questions and got a response to 1 on of them:

My opinion is there is something wrong going on with this car.
