I doubt if this is your first new car. I also doubt if you believe this is normal. However, you seem determined to give your dealer impunity, so you will have to live with your decisions.

A few years ago my brother bought a new Winnebago motorhome...30 footer...from his local RV dealer, which sold 3 lines. It had a myriad of problems: roof and window leaks, a/c was not wired properly, stove worked only on 2 burners, awning was binding, etc. Do you think he should have contacted Winnebago in Iowa ?

 

No, not really intending to give my dealer impunity, as a careful reading of my posts will show.

Yes, I think he should have contacted Winnebago if they were the ones telling his dealer that nothing's wrong with it. Also, it is the manufacturer, not the dealer, who would be buying the car back in case of a lemon law claim, which unless RVs are exempted from this law would have been the course of action I would have followed in your brother's case as that sounds pretty egregious.

 

Wrong. I'd charge you 600.00 per hour until you accepted others know a touch more about agency and defective product law !

 

Fortunately, you're not my attorney.

 

If your attorney disagrees with me, ask him to contact me. I can always learn something new !

 

Welcome to my ignore list. Bye.

 

You are not too appreciative of advice.

Seriously, all of us here would like another legal opinion.

 

WTF, is this the personal BS section now? How about getting it back on actual problems/concerns and solutions. Take your pissing match's to You Tube or Twitter.

 

I'm talking about exactly that: solutions, regardless of the labels you want to attach.

It appears a number of C8 buyers who have mechanical issues are not inclined to take advice !

 

I just added him to my ignore list. Even simpler.

 

Back to our regularly scheduled program....

Improviz - Have you ridden in or driven another C8 to compare your whine to?

 

Woke up yesterday to a dead battery. Jumped the car and had a warning about the EPB. I actually had never turned the parking brake on so I cycled it and the warning went away. The manual mentioned that cycling the EPB numerous times with the car off could drain the battery so I suppose a glitch with it could do the same? Anyhow, fingers crossed that she starts this morning or I will be paying the dealer a visit. Also makes me want to get the GM Battery tender.

 

Question--- When you tried to start the car and it was low. How long had it sat since last ran for some amount time? I suspect <have not set up any meters to test> the car draws more than past models, due to all the electronics even when parked. Though the majority of systems are off, it is still linked with the sat systems. That could be incorrect. I'd like to put a data logger on the data cable and just run it for 24 hours. All my loggers on shelf don't register anything under 5 amp draws. Might scrounge thru and see what is in the storage room of crusty equipment.
My only reason for this conjecture. Last time I had drove mine and parked. Put the tender on the next day. To my surprise it took it several hours to cap back off.

 

I just got a call from my courtesy delivery dealer, I was supposed to pick up the car (HTC) today. Apparently the back window is off it’s track in some manner causing a gap on one side. I hope they discovered it BEFORE they washed the car and that a wet interior wasn’t their first clue. Their Corvette Technician is going to look at it on Monday. It’s always something.

 

Strange issue, hope it goes alright. please do update as you can. How does one get window with a short travel off the track? Be worth making note.


Best of luck

 

Brace for the possibility (not necessarily probability) for future little surprises. If they visit, hopefully they’ll be minor annoyances.

 

Yeah, this isn’t my first car, lol. It’s all part of the ownership “experience”, with any car. I try not to get too “wrapped around the axle” about such things, it’s not healthy and there is nothing you can do about it anyways.

 

No, but I’ve been driving performance automobiles for decades and none have ever exhibited this sound. Plus, if you Google the symptoms that I’m getting, it comes up with typically something wrong in the differential, bad set up etc.

The dealership has a guy who works there and owns one, which they drove to A/B (they were supposed to do it the following day but even after several pings didn’t do so until I CC’d the GM of the dealership 10 days after they drove mine, and lo and behold, within 15 minutes it had magically been done). So yeah, not exactly a good way to do a comparison, so I want to get a ride in this car and see for myself if it sounds anything like mine. I kind of doubt it, but will see.

I will take it out for a spin later and get it on video, will post here.

 

I'll try and capture mine on a video - If it comes through I'll post it.

 

Thanks. Not 100% clear, though: does your vehicle have a whine like what I'm experiencing? (I'll add it here just to save you the trouble of having to hunt for it).

Vehicle needs to be warmed up a bit for this to happen (5 miles or so of normal driving should do it), and it gets worse at higher outdoor temperatures. So basically beginning at 37 mph I can hear kind of a grindy whine (at this speed it is the worst in terms of more grind/less whine, the grind almost reminds me of the sound when someone is cutting a duplicate key at a hardware store) which occurs at like a crusing-speed throttle level, i.e. pretty light throttle. If I let off on gas, it stops. If I declutch it (pull both paddle shifters at same time, which takes it out of gear), it stops. If I increase throttle pressure, it stops. Its pitch stays same regardless of what gear I'm in, only varies with vehicle speed so definitely not in the gears, sounds like it's coming from the differential or possibly driveshaft-related (bearings, I'd assume).

Once it gets above 40 mph, the grinding sound goes away but the whine gets louder, peaks at about 45 mph, but continues up above 50 where it starts to die down, and goes away altogether above 57 mph (this has gotten worse over time: before it would go away above 50 mph). Needless to say, sound characteristics are easier to distinguish if you don't have the fans blowing at max, windows down, radio cranked. But it's definitely audible while stereo is on at low to moderate levels. Sucks because this car is so quiet, I like to just cruise around in "GT mode" in tour mode, and it's like nails down a chalkboard.

Interested to know if anyone else has any symptoms like these, and a recording would be fabulous. I'll post up some PDR video of it later.

Also one other thing I've found is that if I'm in tour mode driving at a steady speed in tour mode (this is not when it's in cylinder deactivation mode, I checked) and punch it, it downshifts quickly and then spazzes out, either hesitating for a good second or so after downshifting to accelerate or kind of brickwalling at 3,000-3,500 rpm and just holding it there like it's at the rev limiter, and finally accelerating a long time after I've hit it. In other instances it behaves as if it downshifted, and then someone just feeds in the throttle very gradually although it's to the floor the whole time. Very weird.

I did try sport mode a few times but haven't been able to replicate it there, I'll give that a go again here shortly, getting ready to head out.
