Heidi Hill was on the ship on the voyage before Dlouhy's. She said Triumph had be tugged to Cozumel.
"Now people are stuck out there in horrible conditions," Hill said. "It all could have been prevented."
Carnival said Monday that the previous problems were not related to the fire.
"Carnival Triumph previously experienced an electrical issue with one of the ship's alternators," a statement from the company read. "Repairs were conducted by the alternator supplier and were fully completed on February 2. There is no evidence at this time of any relationship between this previous issue and the fire that occurred on Feb. 10."
KPRC Investigates discovered Carnival Triumph had one other mechanical failure back in 2010.
