For Sonata, be old or new versions, 1 out of 100 got
problem on dashboard lighting.
Check it, look at the digital clock with blue LED lighting,
switch on the headlamp, if the blue LED clock still on, lights on
AC and gear panel are on, then is confirmed OK.
Also, for old ones, check the engine room, if got plastic
steel patching especially near the wheels, guarantee accident one
lah, if got more plastic steel patching, must be a damn serious
accident. Any car that got accident before is guaranteed out of
alignment, becareful.
Once I went west coast 2nd hand car to help a buddy wanting to
buy a second hand car, a Altis, sale guy insist low mileage as
shown, accident free, knn, open engine room only, see patch
here and there...forget it.
Once engine is out of alignment, after driving a while, about
20000km, you find lots of play on the steering wheel, your turning
will not be accurate, cranking sound can be heard from the rear
wheels and pixels due to centre axel out of alignment after
impact.
New sonata faults as we download from west coast pier is the
electrical problem, they have a problem in stablising the discharge
of power, result in bulbs blown due to sudden overcharge, usually
the rear tail lights, front lights and brake lights get
blown.
The korean hyundai engineer told us, alway off everything,
from aircon to lights before killing off the engine, and also
start the engine first before on everything. And that apply to all
vehicles.
