I have a 2005 XG350L it will be a year old next month and has 6300 miles. I
dont drive much at night but had to last night and noticed that with the
headlights on and the air conditoner running ( climate control ) that
everytime the air kicked on the lights would dim....is this normal, I dont
remember my wifes Santa Fe or our Tucson ever doing it, I could be wrong and
just happened to notice this one. Second concern is when breaking I get a
slight pulsation in the break pedal between 20 and 30 MPH noting above that
or nothing below that. I can see the rotors though the wheels ( custom
wheels ) and they look perfect no ridges ,scatches ECT. front or rear. Any
suggestions

Tunez

 

You don't drive much more then I do. Vought mine 12/07/05 now just under
2400 miles. Will take it in next week for an oil change.
anyhow I don't have either problem for what ever that may be worth.

The lights briefly dimming when the a/c compressor turns on is normal. The
compressor clutch draws a large amount of current when it engages, causing
a brief voltage reduction.

For the brake vibration, your rotors may need to be resurfaced. If you
let the vehicle sit for days without driving, you may be building up rust
on the rotors (possibly on the inside surface you cannot see).

Thanks both John and Hyundaitech

I guess the rotors may need to be checked further, I only drive about once
or maybe twice a week and mostly less than 20 miles round trip, I never
thought to check the rear of the rotors. I did do a kinda no-no ( well
kinda ) 65MPH and stomped on the brakes, the pulsation did seem to lighted
up even more but will have dealer check them out when I get it serviced.
Thanks again

At that rate of mileage accumulation, you guys would be as far ahead on
a bicycle. :-)

I got my Sonata last December 20th and have nearly 8,000 on it already. :-(

Why is that a "no no?" That may be exactly what you need to cure the
pulsating brakes. Try 4-5 hard stops from 50 MPH or so. If the problem
is rust spots or uneven accumulation of brake pad material, this will
often fix the problem.
