It also matches my experience.

Actually, a lot of aftermarket, and even some OEM rotors will warp from the
heat from semi-metallic pads.  The break-in stuff is more hyperbole than
reality, as is the theory of hard braking.  What really addresses this
problem best is a quality set of rotors and ceramic pads.

You may also want to check your driving habits and pad break-in
procedure as rotors rarely actually warp.  The pulsing is often a result
of uneven deposition of brake pad material onto the rotor.  This can
often be corrected with a few 5-10 really hard stops to heat up the
rotor and redistribute the material.  Also, try not to stop hard and
then hold the brakes for any period of time as that will cause pad
imprinting.  Try to let the car roll slowly ahead after a hard stop
rather than standing on the brakes afterward.

I recently rented an almost new Camry and thought it was not onl
boring but dangerous.  This 4 cylinder had a hard time getting goin
if starting out on a small hill and the suspension is very soft an
wavy.  So I can understand why you are not happy with the Camry

I have a 2002 Sonata V6 and it has been a pretty good car and I a
hoping for 150K miles before the end.  It now has 74,000 miles on it
There is nothing major wrong with the car that I know of but littl
things are starting to malfunction like the gas door doesn't ope
when the switch is depressed

One big issue:  the brake rotors keep warping and Hyundai refuses t
fix them under warranty even though it was still covered under th
bumper-to-bumper.  That was a bad decision by Hyundai America.  
have now replaced the rotors and pads with high performance model
and hope that solves the problem

Next time I will buy a Honda which has yielded better performance an
reliability for me in the past. Good luck

no real problem. but wonder what you think about the 2007 & 2008 sonata
V6.  drive a camry and thinking about selling it and getting a 2007 or
2008 sonata V6. retired but work for hertz part time and of all the cars
we have in the $20000.00 to $25000.00 price range the sonata V6  is the
most fun to drive. handles great and lots and lots of power when you
need it with pretty good gas mileage. just wondered if you think the
sonata is on par with the camry and hold up in the long term. any real
problems  with the sonata or complaints from owners? my camry is a 2006
le 4cyl. great car but oh so  boring.   thanks   DAVE
