XG350 2002 multiple das indicators lighting - Seedometer died.

Mt wife was almost home on Friday when the brake, Battery, TCS and ABS
lights all came on and the speedometer stopped working. I turned the
engine on today and all the same lights came on, but I did not want to
risk taking it out of the driveway to check the speedometer. At one
point the engine hesitated, the radio went silent for a split second
and the battery light extinguished and stayed off. After turning the
engine off/onagain all the lights were back on again.

Any help here? It should still have the 100K, 10 yr warranty, but if
it is just time for a new battery, I can save the time and just get
that, unless it is also covered in the warranty. Maybe someone knows
about that, too.

 

Sounds like the alternator to me. I know that if the alternator goes out,
both the battery and the brake lights will come on...its wired that
way...don't know why. Don't know about the TCS, ABS, or speedometer, but
the alternator is the place to start. Quite a job on the 2002 XG350. Get
it to a dealer for some warranty work. If it failed just as the car was
getting home, and if you only started it one time after that, your battery
should be almost fully charged. We drove 50 miles to get the car home after
our alternator failed without any problem. Just keep all electrical stuff
off... No radio, headlights, A/C, heater, etc.

Sounds like the alternator to me, too. The ABS/TCS will deactivate an
turn on the warning lamps if the system voltage becomes too low. Due t
the electronic nature of the speedometer and other items, low voltage ca
indeed cause them to malfunction

 

Turns out the warranty was 5 yr 60K and we have >70K. dealer wants
$500. Is it really that tough to get to and replace it myself?

 

The labor guide I looked at called for labor time of 1.6 hours.

It's no cakewalk. If you have the equipment, you can discharge the a/c
remove an a/c line and coolant fan, and squeeze it out. If not, you'l
need to remove the radiator.

Open your hood and look at the alternator. You'll probably understand

You can do it yourself. The alternator will squeeze out/in without removing
the radiator, but just barely and only in one orientation. Cut a piece of
cardboard to cover the radiator fins to protect them, if you cut the
cardboard correctly it will fit right into the radiator frame. I believe I
did take the radiator mounts off so I could move it a little, but I did not
have to remove the coolant or take any of the hoses off. I did two 2002
XG350's.

The other alternative, if you haven't done the timing belt yet, is to get
them both done at the same time as a lot of the labor overlaps.

When should the timing belt be replaced?

 

Book says 5 years or 60,000 miles which ever comes first. But, according to
Hyundaitech, the X350's not noted for having timing belt problems. I did
mine at 90,000 miles (5 years) and did my wifes at 60,000 (5 years). I'm
at 125,000 miles now (7 years) and for sure will wait until 180,000 and then
I'll have to decide whether a 3rd timing belt is in order or not.

Is the Hyundia eng a critical eng. in that if the timing belt breaks major
damage will result or will it just stop running?

 

To my knowledge, any Hyundai engine currently in production has th
capability if serious damage if the timing belt (or chain) fails

 

Yes, its an interference engine. Bad news to have the timing belt break.
