I had a situation w ball joints and it was severe.
Also note the rotors, slotted or not, are not made of silly putty
- there is a reason for such warpage that needs addressing.
Slotted will cool better at some loss in brake distance.
Often people just blame the rotors and warpage as simple as they blame Congress.

if the steering shakes all the time: rims/tires/balancing/ball joint
if the steering shakes on high speed braking (example: 70mph-40mph): rotors
if the steering heavily shakes when your at a complete halt: GTFO and go see a doctor

I haven't had a chance to really drive fast because I mostly drive in the city. I got a chance to drive in some open roads today. I was going down a steep hill pretty fast (40 mph, which is fast for me). As I was trying to slow down, things just felt like noisy and I think I noticed some vibration maybe. Would I fall in the same category as anionrings here?
I've had this 08 CPO tl for about a month, would the dealer fix this for free? Also what causes these warped rotors, is it from driving through pot holes? Since I live in the city, 90% of the roads have pot holes in them. Some look accidental and some look intentional. Like a dip or shoddy road repair job. I am constantly driving through them at a decent speed. I try to slow down over them if I can, but there are times where I'm just too late to catch them. Does that cause damage to the rotors or damage else where?

^^^ nope....if it makes some noise/squeaks your prolly gonna have to get pads....your rotors should be fine
Yes...take it to the dealer and tell them WTF....be stern and talk only to the service manager and tell him to resolve this, else you will call corporate....
Any car you get (particularly CPO) should be trouble free for atleast a year in my opinion....

The noise while braking at high speed was more like a loudness. It is hard for me to describe the experience clearly at the moment. It just sort of felt like what the OP went through. Almost felt like I was going down rumble strips or something. I'm not sure if I noticed it while high speed braking on flat land, just down hill.

I think its ur pads....
either way...replace the pads and if all is fine, your golden....if not do ur rotors as well....
BTW do you get any vibration while driving and when not on the brakes ?

^^^ there are 2 issues being discussed here LOL....
for the OP (anionrings), the rotors are SHOT....
but am thinking for "burntrat" the pads are def gone and do not know about the rotors and hence I asked him to switch the pads first which are cheaper than getting rotors....and if troubles are not gone then getting new rotors....

I don't recall any vibration while driving. If there is any, it must be real minor for me not to notice. It just felt weird when I tried to slow down from a high speed going down hill. Flat, no real issues, I think and going uphill is real sluggish.

^^^ yeah its ur brakes.....
if you get vibration all the time....rotate and balance ur tires and check axles and suspension....
For uphill....time to mod her to get some more low end TQ

Would worn brake pads explain the lowered brake sensitivity I've been recently experiencing? When I first got the car like a month ago, I could tap it and it would start to slow down on flat land. Now I have to press at least half way on the brakes for it to kick in. Also, there are times when I depress the gas completely to coast a bit then hit the brakes to slow down, and after a certain point, it feels like it's accelerating on it's own even though I'm hitting the brakes. Is that normal?

^^^ the brake pedal feel has also things to do with FLUID and the brake lines....
when was the last time you did a brake fluid flush ? also do you have SS lines or rubberized lines ?

I have no idea whether I have SS lines or rubberized lines. Would checking the lines involve me taking off the wheels?

not really....you will see a line running to the caliper....and i can bet it Rubberized line....
but yeah I would expect the dealership to do it as well....I would go there and tell them to do a brake inspection/replacement of whats needed, else you will call Acura corporate....that is ridiculous that you just got the car and have to do all this....
dont delay anymore....go talk to them....

I think I noticed some roughness/vibration while braking on flat land. I thought it was the crappy road. I can't say for sure until I find some smooth stretch of empty road to test on.
If it is rotor related, that would be covered in the warranty, and nothing would come out of my pockets right?
If it is just brake pad related, how much would that cost me? Also, will the inspection cost me something?

I don't think warranty covers your brakes and tires cuz they are wear and tear items....at least not my dealers...better check first....but ur rotors definitely need to be replaced...

^^^ i agree, warranty doesnt cover any wear and tear parts....wheels/brakes/etc
but if you just got the car a month back you can go back and tell them WTF i just got this car and blah blah blah and they should goodwill it for you....or atleast pick up 70% of the tab....
if you have to replace the brakes pads/rotors and you have to pay 30-50% to the dealership, it better to just get it replaced by aftermarket parts....if they are goodwill-in it for you then might as well get it done at the dealership....

if u only had the car for about a month, take it back to the dealer asap, i m not sure if this info is correct, but dealer need to make sure that all tires and brakes have at least 50% of life before they put it on sale, and another factor is that how many miles have you put on since u got the car....
MOST PROBABLY they will goodwill your brakes but i highly doubt it, I wouldn't be surprised if they come back and tell you this is a common problem and happens to a lot of TL...blah blah blah.....if u r the kind of person who doesn't like to argue with ppl then bring a bitch with u...LOL...check to see what other problems ur car has so they can check it at the same time....they replaced my front driver sidemarker last time i went there bc my rear brakes was squeaking altho that was 2 weeks after i got the car from them, I told them I am not paying anything and they told me i shouldn't either since I only have the car for 2 weeks.

I was talking to a friend about the symptoms and he thinks it's just the ABS kicking in. Can someone describe the ABS "feeling" to me? He drove my car for a little bit and didn't think there was a problem with anything.

^^^ NOPE thats not the ABS....
When ABS kicks in you will hear ticking noise....and it kicks in when it detects slip....imagine heavy braking where the car is not able to stop and you have the pedal PRESSED in...then ABS kicks in...you hear a ticking voice and no vibrations/steering movement....

Ticking noise from the wheels?
ABS only kicks in when the brake pedal is pressed all the way? Is it possible it is kicking in now because I have to press harder than before?
I was trying to see what ABS was like and saw this on the acura site:
"Sometimes an ABS creates noise and causes the brake pedal to vibrate when the system is activated."
I think I might be hearing/feeling 'ticking' and just describing it wrong to you guys.

^^^ yes the ticking noise will cause a little pedal movement (not really vibration)....you will be able to feel that ticking noise....but as i said there will NO STEERING vibrations which you are experiencing....
PS: the noise is not from the wheels....its from the controller....its not loud, its a faint sound but you can feel it on ur brake pedal....slightly...it goes "tick tick tick tick tick...."
here is a little overview of how the ABS system works....

here is a little overview of how the ABS system works....
The controller monitors the speed sensors at all times. It is looking for decelerations in the wheel that are out of the ordinary. Right before a wheel locks up, it will experience a rapid deceleration. If left unchecked, the wheel would stop much more quickly than any car could. It might take a car five seconds to stop from 60 mph (96.6 kph) under ideal conditions, but a wheel that locks up could stop spinning in less than a second.
The ABS controller knows that such a rapid deceleration is impossible, so it reduces the pressure to that brake until it sees an acceleration, then it increases the pressure until it sees the deceleration again. It can do this very quickly, before the tire can actually significantly change speed. The result is that the tire slows down at the same rate as the car, with the brakes keeping the tires very near the point at which they will start to lock up. This gives the system maximum braking power.
When the ABS system is in operation you will feel a pulsing in the brake pedal; this comes from the rapid opening and closing of the valves. Some ABS systems can cycle up to 15 times per second.

I apologize if I wasn't clear before, but the vibration feeling wasn't in the steering. I felt it more in the brakes/wheels area. I really wish I could put these feelings into words, but it is hard for me. Ok... that just sounded like a line from a romance movie...anyways, I'll pay the dealer a visit and see what's up with my brakes. I think I'll have them bleed the brake lines. Might be air in my lines causing me to brake harder then before. Pressing the brake pedal half way basically does nothing. Only after that, I can sort of feel it slow down. Feels like I have to press like 80-90% to get a full stop from a decent amount of speed.

^^^ dont get me wrong but if the wheels are vibrating how is the steering not vibrating ?
I was about to ask you about your pedal feel....
if you pedal feels like real boobs (nice and soft) there air in ur system
if your pedal feels like fake tities (hard and pokey), you good to go....
sorry for the dumb analogy....but you said romantic movie LOL....
again to sum everything up:
Slight brake pedal vibration, movement, ticking noise: ABS kicked in YO !
Steering vibration while braking: Rotors are shot
Noise and steering vibration: Rotors and Pad
Noise while braking: Pads are gone
Squeaking: Apply some grease
Soft Pedal feel: Air in system, leak in line.....

no, that analogy was perfect. i can relate to boobs, i think we all can. brakes are not real, but i guess more on the fake side. i just have to push down harder like almost all the way sometimes. how do i remedy that? i want it more responsive.
im leaning more towards abs now. im not getting like a constant vibration, more like a vibrating in short intervals. i guess like if i were to have a flat tire. like the wheels are trying to lock up to brake, but won't let it. no real feeling in steering wheel, just the lower portion of the car. i feel it in my feet more. if this is the abs, is it normal that it's kicking in at like 40mph? i thought it was something for higher speeds?
