Don't trust my Service Department - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

kaos_ss · 11-25-2013, 05:52 PM

I live in an area that only has one Chevrolet dealership and I've had some horrible experiences with the service department. Recently, my ZL1 started making a "humming" noise which seemed like it is coming from the rear end. I saw other posts on the forum about a bulletin that describes a similar sound and suggest changing the rear end oil. So this morning (8am)I dropped off the car at the dealership, explained the problem, and showed them a copy of the bulletin.

I didn't hear anything all day so at 5, I called and was told that I mechanic drove the car and he determined that the noise wasn't normal. But he wasn't sure what the problem was so that they were waiting for another technician to drive the car. At 5:45 I get a call back and was told that the second mechanic thinks the sound is coming from the differential so that they want to "drop the rear end" to see what is causing the noise. But because it is a few days from Thanksgiving that they would like me to go pick up the car and take it back next Monday... because if they started working on it tomorrow it wouldn't be done before the holidays. They said they wouldn't want me without a car for an entire week.

So I don't understand why an entire day was spent just to confirm the "hum." And why don't they start with the oil change to see if that solves the issue rather than take the entire thing apart. And not to be an ass but I don't even trust them taking it apart! It gets so frustrating. I know problems can exist even if the car is new but damn it sucks!

Any suggestions?? Or comments!??

Go to a different dealer with the bulletin and see if they will change the oil. ...OR tell your dealer to perform the bulletin first, and if the noise doesn't go away, you'll bring it back.

I don't know the history of your "horrible experiences" however I would be pleased that they didn't just change the oil and sent me on my way....my experience has been that by the time you hear a noise the damage has already been done.

Also, why wouldn't they supply you with a rental...when I had warranty work done they gave me a rental until the car was ready....I certainly wouldn't be comfortable driving the care over the holidays when the rearend doesn't sound "normal".

But I really like my dealership - Prince of Albany, GA.

I agree with trying another dealer. However, I will say that waiting an entire day, if not more just to diagnose the problem certainly isn't out of the norm at a busy shop. Also, like those above have said, I believe a rental is in order.

S3XPanther · 11-25-2013, 06:34 PM

They can't just take your word and follow the bulletin. They have to confirm it for themselves.

AG1LE · 11-25-2013, 06:35 PM

His area has only one chevy dealership...I wonder how far he would have to go to find another...

I agree and definitely understand. I wouldn't expect them to take my word. But if they have determined that it is making a sound, wouldn't it make sense to change the oil first to see if that solves the problem?

I guess I'm just worried that they won't be able to put the car back together correctly!!

My first Camaro was a 2010 SS and after 4,000 miles the transmission went out. They pulled the transmission and tried replacing parts inside. When I got the car back it was worse then when it went in! I don't want the same thing happening here.

Wow! Sounds like a cool dealer. I was told that despite the sound they determined that the car is drive-able and it shouldn't hurt anything driving it until next week when I can take it back again.

I have changed my rear differential fluid already twice and it is real easy.
Make sure you put the slip differential additive as well.
Takes only a few minutes to do.
Also when doing it yourself make sure you open upper bolt first!
Good luck.

Buy some AMSOIL Posi Lube and be done with it. On my 2011 it was changed 3X and came back every 2000 miles. Changed to AMSOIL and no more problems. It is Posi clutches

kevinw · 11-25-2013, 07:27 PM

if you dont trust them, then certaintly dont have them do anything on your car. you have a very expensive car, and if i were you, i would seek out another dealer or call GM directly. i agree that on a new car things may happen, but you want a dealer you trust and feel comfortable with. if you dont, you got to move on to anohter or it will always bug you.

DocMartens · 11-25-2013, 07:29 PM

I recently bought a new Camaro too 14 and I am hearing a noise from the shift knob that is annoying, It is louder when I accelerate. When I hold tight on the shift knob the noise quiets down. I am frustrated with this too because it is brand new and now has only 150 miles. My dealer ordered a part and I hope it fixes it. I also have to have the rear diffuser replaced for cosmetic reasons, large white spots. OP, hope you get your noise fixed and have better luck
