Hi,

My sister owns a 2003 Santa Fe (no ABS) with about 15k miles in it and twice in the last month she has experience what seems to be a brake system problem. She describes it as like if something is preventing the vehicle from moving. When it happens, she can only go up to 20mph. There is no CEL or any other lights. The brake pedal becomes hard, like if it has lost power assistance. In both ocassions the vehicle can be driven normally after shutting down the engine and sitting for a while. It does not seem like distance/running time is a factor, since she has done several long trips without the problem occurring, but it seems to happen after the vehicle has been running for some time (never at cold start).
I have searched the Hyundai's Service site for possible recalls/TSB to no avail.
Any suggestions? Has anybody experience anything similar?

Thanks!

 

Sounds like she needs to leave it a the dealer and have this problem addressed . No guesswork on safety.Dealer need to drive vehicle until problem duplicates.She might have to leave it but safety is more important than convinence.
