Unfortunately, I am having issues with my 2016 Z06. On Saturday it stalled on me at a light, and I could not get it started. I had it towed to a local dealer and they replaced the battery and fuse block on the battery. They are saying it still wont start and they need to confirm the engine will turn over manually at the crank.



Any ideas what might be wrong? Car is 100% stock with 2,500 miles.



Thanks in advance.

Sorry to hear it.

We’re there any noises/symptoms/changes in behavior before it died on you?

When you tried to restart it, did the engine turn over? If no, any sounds at all when trying to restart?

Did your dash /gauges stay lit up, or did they go dark after it died?

Do these cars have a crank sensor, or cam sensor (forget what its called)? I was going to say maybe a fuel pump issue, but I think it would at least turn over and try to fire if it was that..but if it does not even turn over then maybe something else

Thanks for your reply.

The gear position section went blank while i was driving so i could not see what gear i was in. Its a M7. The dash stayed normal other than that and check engine light coming on and along with antilock braking symbol. Other symptoms were a small rattle which sounded like it was coming from under the shifter and the shifter felt "loose" in gear. I was trying to pull over to safe spot before it stalled on me.

Maybe it senses that it's in gear and clutch is not engaged. I have an A8 but wouldn't it not turn over if this is the case? As a safety failsafe?

Why did they have to replace the fuse block? Did something else happen to this car prior?

no the dealer said after they replaced the battery the starter was dragging and shorted out the fuse box

I was initially thinking a gear position sensor, but since the starter not turning over burned the fuse, that couldn't be the case since it was trying. Could the starter and/or flywheel be locked up? Not an obvious solution, but probably more common than the motor being frozen up not allowing the starter to turn it. A long time ago I had a car and the starter broke leaving a small part of the gear/cog stuck in the flywheel. 2 different shops I towed the car to told me they couldn't turn the engine with a wrench on the crank and said I needed a new engine. Not accepting their diagnosis, I pulled the starter out and found the real problem. Hopefully you'll get lucky with something similar. I had no symptoms as the car ran great. Parked it, went into a bar, came out later, turned over weakly and then nothing. I thought I had a dead battery, but the lights and all still worked. Just wouldn't turn over. Walked home and came back the next day to charge the battery. Still no luck so I had it towed to a local shop. Then the 'need a new engine' saga began, So I say, If the engine won't turn with a wrench on the crank, I'd pay them to break it down to find out why it's not turning before spending big $.

Well it would be nice if it were just the starter but that doesn’t explain the gear indicator and the fact that it died o you. Dang it.

Thanks for the info and for sharing your experience. I’m pretty bummed out at the moment hoping for the best. Hopefully they’ll be able to manually turn the engine.

yeah have them run the codes on the computer see what pops up.
things i would check depending on the codes is the look of starter and the area of it, possible even taking it out as mentioned. see if it evening moves manually then. id check oil condition, pulling the spark plugs (especially if it still doesnt turn over manually).

best of luck with the least amount of work hopefully to get it running again.

That's what happened to my 2016 when the engine seized. Hope that isn't your problem.

So that I can begin planning for worse care scenario. If the engine is bad what would you all recommend I do? Cut my loses and sale the car as is? Replace engine? Can I have it rebuilt? Open to any ideas. Car isn’t under any warranty.

Thanks

Only you can answer the question of selling the car, but if you want to keep it I would take it to a Chevy dealer and have them install a LT4 crate engine. Then you will have warranty on the new engine and all things else considered I think it will serve you best. When you go down the "rebuild" rabbit hole you open up to all sorts of other problems with supply and availability. not to mention if the block trashed. I hoped mine wasn't, but of course it was. I race my cars. It doesn't sound like you do. A GM crate motor is the way to go.

Thanks for your input. Good point with avoiding the rebuilding.

I went through it all last year. Block ended up being trashed. I bought a custom LME short block and went crazy from there. Ended up spending around 3 times the cost of a crate engine, but I like to drag race and have done so for 45 years. I guess I'm not going to outgrow it. Lol

Nailed it!

Still waiting to hear from dealer. They been backed up and haven’t had a chance to try to manually crank engine. No matter what happens this z will be back on road!!!!

With only 2,500 miles, hopefully it’s not a fragged engine.
