Just received a safety recall notice from Hyundai on my 2008 Elantra.
Problem seems to be with the electric fuel pump motor inside the tank. They
say they will replace the fuel pump subassembly. At no charge, of course.

Has anyone had any of the problems they say may be caused by this?? "Poor
engine starting and hesitation may result. Other engine performance issues
may also result and may lead to a crash."

My Elantra has just turned over 5800 miles with nary a "hiccup" to this
point. I've actually been disappointed that I've had nothing to cripe
about.

 

I'll chime in as someone who's had to diagnose these prior to the recall
being issued.

The typical scenario is that the car would arrive with a complaint of a
check engine lamp and perhaps a complaint of poor performance. The fuel
pressure would get low enough that the check engine lamp would illuminate
due to the significantly increased injector on-time over what would
normally be expected. If driven long enough the vehicle would misfire or
even stall out completely.

The typical sign that you're having a fuel pressure issue is that the more
the accelerator is depressed, the less power you get. Usually, this occurs
after the vehicle has been driven a significant period of time and the fuel
pump begins to overheat.

As far as a crash, that's highly unlikely in my opinion (presuming you
have enough sense and enough space to coast to the side of the road).
Nonetheless, the inconvenience of a barely (or not at all) running vehicle
varies with the situation.

I had this happen once, and I coasted to the side of the road and waited
about a half-hour for the pump to cool off. The tank was nearly empty, so
I drove to the nearest gas station and filled my tank to help cool the pump
while driving. I then made the 45 mile trip home without incident.
