2003 Camry

[cwb]

Having problems with brakes and ecu. Dealer replaced ecu first time in (4 months old, brand new/zero miles when I bought it) Smoke was coming out from under left side front. They said it was ecu needing replacement. After ecu was replaced car still continued having problems with what felt like dragging or lack of acceleration (especially pronounced in stop/go traffic0. Before third time back to dealer in less than two weeks, car would not move at drive- through bank (forward or revers) about 2 weeks after ecu was replaced. Had to stomp on gas to move 10 feet and front wheels turned but back wheels locked up (people were hollering turn off your park brake). After having towed in for 2nd time dealer is now saying that brake fluid is contaminated and asking me to fork over over $1000 for brake repairs. I think dealer missed something with abs system and is trying to cover. Anybody had similar experience or advice/
