Re: 2002 Elantra won't accelerate when engine is cold and humidity i
I'm in Canada, therefore the ECM code isn't the same as US models. The
service manager contacted Hyundai Canada and they told him what code to
download. The issue has not occurred since the ECM was flashed, but the car
now behaves sliightly different, i.e., acceleration is smoother than before.
The service manager admitted that other customers complained about that same
issue and that they could never totally resolve it.
At the same time, the dealer finally resolved the rear brake noise issue.
Whenever we drove or braked at very low speed, we heard intermittent noise
from the left rear area. It turned out there were 2 issues: the left hub had
to be replaced and that corrected a faily loud noise at low speed (it did it
without braking). A new strut corrected the noise when braking at low speed.
Replacing the wheel bearing, the drums and shoes didn't help at all, but we
now have brand new brakes in the back for free.
Thanks for your help.
