Hello Hyundai Tech and everyone else!

My Sonata has been not wanting to start on a couple of occasions and at
times seem to quit for a split second while driving along at 50mph.

Then she would start but die in a minute or so, yesterday.

Took her to a trusted mechanic and was told it likely had to do with a
drive-shaft sensor which would be indicate by the symptoms I stated.
I thought it may be dirty fuel, fuel filter (s), or pump.

The mechanic said that repair meant removing the motor and that I should
have the timing belt and waterpump replaced as is the timing on 75k milage
indicates.

Does this sound resonable to the knowledgable people in this group?


Thank for any information!

 

I think your mechanic is probably referring to the crankshaft sensor.
That would be consistent with what you describe as well as the
mechanic’s thoughts about the water pump and the timing belt. The
engine doesn’t need to be removed, but all the items necessary to
reach the timing belt do.

If you haven’t yet replaced the timing belt, don’t hesitate to do this
repair. This engine has been known to have premature timing belt
failures, so I recommend at least strict adherence to the schedule for
replacing the timing belt and balance shaft belt, which is every 4
years or 60,000 miles, whichever comes first. Given your symptoms,
this is also the time to replace the sensor.

The water pump is another issue. They don’t fail all that often, but
with the timing belt off it’s only a small amount of additional labor
to replace. On the other hand, if it fails later, it’ll be a
significant amount of labor just to access the water pump again.
There are differing philosophies here, and you’ll need to pick your
poison
