Well my car is back at the dealer for its 3rd diff.

My my dealer service manager I like and he does a good job.

GM Customer Care is a PATHETIC JOKE.

I understand that crap happens and parts fail, but my car has been out of service for over 12 weeks on warranty repairs in the first year I've owned it WTF.

just the wasted time back and forth to the dealer for service, arranging drop off and pickups etc is ridiculous. And trying to schedule a trip or eevent around the cars out of service dates or wasting time breaking in another then another diff is frustrating as can be.

Do do I get a crappy loaner sure but if I wanted that I just would've bought the crappy loaner in the first place

Just wanted to share with you all that that crap GM writes in the books about the importance of your happiness is COMPLETE AND TOTAL B. S.

not sure what the point of your post is. why wouldn't you just exercise your lemon law and swap out of it? each state has slight differences in the law but pretty sure 12 weeks and 3 attempts covers most if not all of them....

Sorry that your first post on this forum is not on a good note.
What did GM CS do?

This is an easy buyback case and I am sure if you had talked to the district manager, he / she would have made it happen without the need for an outside help.

If this is real, you should have no problem picking up a new 2017.

I bought the car out of state and had it shipped so my local lemon law does not apply.

The he lemon law in the state that sold it requires I try the BBB Autoline process which I have done BUT to proceed through arbitration will require an inspection in the home state. Per bbb. So ship the car to some undefined person 1200 miles away and nit have a car for who knows how long or just try to band-aid it again so I can try to enjoy the 100k purchase for what amount to 3/4 of the time I actually pay for it. GM CC knows this, it is part of the mediation and they have just stone wallled


sure I can hire an out of state Atty to fight it and pay him or her, and do the interstate thing, but the car is absolutely a lemon in every state based simply on the time out of service without question and GM hosing me Knowing the hassle is a deterrent.

Sorry it was first post. I do lurk a lot however. I wanted to love this car. But dang, how could you deny that 12 weeks in a year is a lemon regardless of the technicality of state of purchase.

And actually 4 repair attempts appears to me the standard. Or 30 working days usually cumulative out of service.

BBB is a scam. You should contact a lawyer and let them deal with BBB.

Or should just speak with the district manager first and discuss a buyback option instead of wasting time and money on a year battle for lemon law.

Diff fail #'s 93,94,95. (Op)

I would quickly call GM customer service number and get a case number. (That part is a must)

​​​​​​The better route here is to obtain a buyback like so many others have, for blown diffs that didn't get fixed in time, or too many times, for the owner to tolerate such nonsense.

Talk to a Corvette Master Mechanic, or if you can buy one a beer and talk about it you will be amazed. Did the C7 Z06 break sales records? I believe it did, however that does not mean it was ready for prime time, or durable.

From said master mechanic, he is seeing a very large diff fail rate, and also the flex plate issues. Throw in the AFM issue with the rear cylinders, and as a standalone issue, the OVERhEATING........yeah he's real busy these days.

So OP, how will you feel when it fails a fourth time? More inclined towards a buyback? Try working with GMCC first. You'll be surprised.

I went through the gm buyback precess years ago on a then new 05 vette. Bbb and lemon law, lawyering up is a waste of time. I used gm customer service and got my buyback in a short period of time. Sounds like you have had enough unresolved problems to merit a buyback.
Hang in there. It is stressful but you will prevail.

What are you doing to this poor car to break the tranny 3 times?

etekberg

If you are going to attack him, the least you can do is understand the difference between a transmission (tranny as you say) and differential.

What were the failures each time? Was it noise or an actual hard part failure? Going through 3 diffs on this car is not normal, especially considering how many are driven hard, tracked, drag raced and beat one without issue.

The car is a 2016 z06 3lz with z07 pkg

I have a gmcc case number. Actually the is the second case # for this car for a diff defect

I requested a buyback from gmcc the second time now and they have refused state into they choose to repair again.

I requested to speak to a supervisor and have not been contacted and was not given contact info. I was however told by fm can that my car does not qualify as a lemon so they will only repair. The car has been out of service for over 45 business days in its first year for warranty repairs so it clearly meets the lemon standard. When I asked for a district manager contact at my dealer I was told that I needed to go through gmcc so I did.

The failure is whine that gets increasing louder

The first failed at 5000 mi. Car now has 8000 mi and it screams on the hiway.

This is unfortunate and its not common to have 3 diff replaced. These differentials are top notch and made in Germany by ZF. FYI, I had my diff replaced on my 2016 due to whine noise. I was told at the time at none where available. One call from the warranty manager to the district manager and a diff was sent overnight and car was running with a new diff 4 days later.


You should contact CS back and demand to speak with a supervisor, from there you make sure that he understand that you will take no for an answer (respectfully) and that you will need the district manager to contact you immediately (They cannot give you his contact info but once he contacts you then you will have his contact info). Ask for email address for the person that you are speaking with and do your communications with emails after that for traceability. Also speak with dealership warranty manager (not service manager). Warranty managers works directly with district managers and should be able to connect you. Good luck!

As mentioned just lemon law the car, no need to get permission from the losers at GM

etekberg

He already said that avenue is impractical to him due to the other state's requirements.
