Don't know what you are wanting in terms of comments. The tire and windshield repairs can happen to any car. The engine issue is more troubling, but does not seem to be a common issue at this point. Would hate for it to happen after the warranty expired though.

Disturbing undercurrent of LT1s grenading b/c of bad main bearings. Agree on the tire and windshield - could happen (or not) to any car.

Sin City

I totally agree with the gearbox issue. This box really needed a gate. With the 7th gear it's just too inconsistent to find the right gear without thinking about it. It doesn't shift naturally up or down.

I can't see whining about a tire going down and a windshield cracking. That doesn't happen to Porsches?

A motor lunching though... yikes.

You CONCIOUSLY have to shift this car or you're going to get hung up. (usually between 4th to 5th). Now I'm sorry I tuned my car because of the grenade issues. I thought I got that resolved when I got rid of my C6Z.

The gear shifting in the M7 is not a problem if you pay attention. Being involved in driving is what makes driving the M7 so fun. If you want to be less connected just get the A6 or A8. Just my opinion and I'm sure others like the A6s and A8s better.

It makes me wonder how many cases of launched engines we had already, this is honestly the first time I see it happening to someone.

Did the lt1 die during a track test or was the engine failure during street use.?

I'd be curious what the answer is.

I think as a performance sports car with Z51 package I think it should still last longer than 6000 miles even if it was all track miles. but again who knows.. maybe it was a bad oil filter.

My 7 speed shifts fine. Just have to get used to trusting the reverse lockout so you can shift to 6th by going essentially to reverse. No problems in lower gears once I installed a CAGS eliminator. Love rev match!
After reading about the engine, wondering why I went through the trouble of getting a “genuine AC filter!” Will check the two very strong magnets I put in the two drain plugs I installed on an early oil change. Maybe a good reason to change oil, at least initially, well before the oil monitor indicates!

Reading about the engine issue is a bit troubling. Perhaps a 1 in a million failure, but not something you want to read about especially on a long term test car. What are the odds??????

I too would like to know if this failure occurred during a track run or normal driving.

dovervold

Well, I think they concur with most everyone else, the C7 is a great car! I installed a MGW shifter, and it truly is fantastic. Best mod I have made for sure. I have been on the fence about modding the motor for some more HP, now I don't have to worry about that anymore. Think I will hang on to the factory warranty

Al Blue4.6l

they imply that it was normal driving. as seems to have been the case with the couple of cars from the forums that needed new motors

Glen e

where are all these "motors grenading"????...On the 3 sites for C7's and reading every day for the last year, , I think I can come across two or so...I can show you that many on any site...why do we always go to the extreme and assume the sky is falling?

There is nothing really new about the LT1, I have no concerns...

They said "We’ve heard of a few similar accounts throughout the Stingray community and GM says it’s aware of the issue" and with about 40K stingrays produced we can't says its 1 in a million problem.

nsxpilot

I think they spent too much time on things that can happen on any vehicle. Really? .....a chipped windshield and punctured tire? Who cares? I also think that if blown engines were a chronic problem we would have had a bunch of postings on this forum. Out of some 40K of them built, there are going to be failures. Despite being a pushrod, 2 valve engine, it is VERY high performance and an occasional failure is inevitable. I suspect per thousand units over the last 10 years, it is a lower percentage than Ferrari, Porsche etc. JMHO

R&L's C6

Odds are still minuscule, and you have a 100k mile warranty. Nothing to worry about.

Mike Campbell

Seriously guys what would you expect from Car & Driver? This was the first I heard of the engine "grenading" problem and wasn't it taken care of by GM? Even if their wundercar Bimmers and Porsches never get windshield chips or flat tires who would know if the shifter had any problems? They wouldn't mention it. I've read that magazine since the 60's and I still have never read a single test that did not take a pot shot at an American test car.

Mike Mercury

why did the mag report the punctured tire and rock-to-the-windshield?

that's no fault of the car. I mean, why didn't they also report the spilled Slurpee - they they had to take their car to a detail shop to get cleaned...

I'd like to hear if the engine took a dump on the track or on the street.

There is a change in a few items including engine oil grade before track use. Maybe that was not adhered to by car and driver?

I. Just guessing or maybe they got a lemon.

I think last months test of the Lamborghini hurican had an engine failure as well....and Lamborghini had a replacement....same color etc in hand to finish off the test.

If the engine failure occurred in the street? Well that's what warranties are for.

Mike mercury you crack me up! Thanks
