Grinding in rear end
1 - 20 of 58 Posts
Yes, I have that grinding in the rear brakes when backing up and turning. My XLR is at the dealer right now for a paint scratch and the technician noticed it on his own as he was moving the car to their garage. They are looking in to it. I originally thought maybe the parking brake never fully released, but no messages ever came up to that effect. If they figure out what is causing the grinding, I will post it here.

Yes! Right after washing the car. Look at the rotors and you will see they rust up pretty well after washing. This is normal as the metal that works best for brakes also rusts easily... not usually a problem since the heat generated by braking keeps them dry. The first couple of times after a drive-way-wash-and-back-to-the-garage results in a distict grinding noise until the rust coating is brushed off.Julie said:

Rear End Noise (fyi)
--------------------------------------------------------------------------------
I had been experiencing a noise from my rear end when I was turning (similiar to the plates in a positraction unit sticking) I mentioned this when I went into my dealer yesterday to get an oil change.
They called the factory and were appraised that there was a "new fix" for this condition. It seems that they use;
-- Positraction Additive GM PART # 1052358 (used in other GM models).
-- GM Synthetic Differential Fluid GM PART #89021669.
I have run the car some and it seems to have quieted down some and I expect it to go away after the new fluid and additive get to all of the rear end parts.
I'll let you know what happens over the next few weeks.

This seems to happen all the time - not just when the car has been washed, and even after it has been driven for a while. I guess it is time to hammer on the dealer. Maybe he can also fix the intermittent screaming fuel pump too.

Fixed
Picked mine up yesterday. On the service notes, they said they couldn't duplicate my complaint (grinding, rubbing from rearend). However, they replaced the differential fluid and added the additive mentioned above and wow - its seems to have worked.
Looks like the service bulletin is the key.

·Brakes?
I remember some folks saying they needed brakes after a short period, I, for the first 7,000 miles used my gears to slow the vehicle and therfore I though I was helping the brakes last longer. After 7,000 more of driving to NYC without hardly using the brakes they started squeeling up front............Is this under warrenty?
I got a sort of negative answer about the brakes from my advisor when I told him I was bringing my car in to be repainted after the terrible job that was done after my crunch on the 4th of July.

·Console heat
As some of you are aware, I got the so call fix for the heat coming from the console which didn't help. Going back east in 100 degree temps, the heat was so bad that I had to shift my body as close to the door as possible to get away from the heat, that I estimate was about 130 to 140. I wish I had had my heat gun from work with me so I could have verified it. I've told my dealer that I want the dash torn apart and a Y attachment put on one of the ducts feeding the vents and have it directed into the front of the console to cool this area. We couldn't put our water bottles in the cup holders or we would be drinking hot water within a half hours. The bottles of water had to be kept by the doors to keep them cooler.
I hope they will listen to me so I don't have to lemon law this vehicle, which I have documented for two times and this will be the third, I will have no choice but to Lenon law this vehicle.
What a shame, they actually crush a lemon so it is not sold to the public.

My 2005 doesn't seem to have this problem. Cup holders are reasonably cool and the seat temp is comfortable.
Cadillac knows this didn't fix itself and somebody at Cadillac knows what refinements were made from 04 to 05.
Stay on their case Bob and you will get it fixed. They don't want it back. :flag

·Thanks Jack, I just have so much to be worked on when I take it in Monday that I'm going nuts.
1. Repaint the whole front end and blend it into the doors
2. Hot console
3. 14,000 and I need new brakes (warrenty or not?) what do you think?
4. Service stabiltrack comes up all the time,
5. RF tire over inflated comes up, and it is only 41 after running for hours.
I still have maybe 5 months for my V so why should I deal with these problems for that period of time. I agree some of these things aren't major like the retractable top not working correct.

·Hi Jack,
When I drop my car off on Monday, I'm going tin to see Scott Allen and see if he is aware of my paint problems. I have a feeling that they have kept him in the dark on this screw up. I'm also going to expect to have a car available for me even though this was an accident, they didn't fix it right the first time. I guess any dealer is only as good as their employees in the technical department. I still think they are tops

Hi Bob....I agree they are good.......
So good that I sent Scott Allen a letter telling him so.
I first went to Allen on your recommendation...Maybe you can get some points for the referral. :flag

·The points would be nice, but I shouldn't have to bring that issue up. I should get great service just because I own a Cadillac, not to mention having a V on order with them. Everyone at Allen agrees that this guy Smith, in the paint department, is very arrogant and after seeing what he puts out, would hope no one takes their baby into him. It seems that he is the only paint tech in that department and has only a few flunkies to do the odds and ends, so in his defense, he is probably over worked and hasn't got the time to bring out perfection in his work.
I know, first I shoot him, then I take him to the doctor. It's tough to say something bad about a great outfit like Allen Cadillac.Bob

I don't know where you heard that, but nothing could be further from the truth. Most cars that are "re-acquired" or "lemoned" are repaired and sold at auction or thorugh the dealership that handled the paperwork. All the DMV requires it that the title be branded as an RAV, Buyback or Lemon Law casualty.
The console heat issue is inherent to the XLR and also the C6 Corvette. I'm not sure if such an issue would be resolvable under the lemon law as it is currently written.
I've never had a problem with the hot console, it fact it stays reasonably cool.
I thought maybe it had to do with my Borla Exhaust giving it better air flow, since the pipes run right down the center. I can't be sure that's it because I put them on within the forst few weeks I got the car. Did those of you that got the Corsa system notice an improvement in your console temp??
