One problem related to brake fluid leak has been reported for the 2001 Hyundai Elantra. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2001 Hyundai Elantra based on all problems reported for the 2001 Elantra.
Took 2001 Elantra to dealer as a result of low brake fluid. Dealer discovered vehicle unsafe to drive and irreparable due to corrosion of rear cross member and/or "spud". It is our understanding that this corrosion occurred in the area where brake fluid was leaking. It has been suggested that the problem is due to road salt. However, we also have a (lower-mileage) 2005 Elantra which we keep parked in the same garage as the 2001 Elantra and which, to the best of our knowledge, shows no sign of corrosion.
