BOSTON -- Leaving leaflets on older Toyota Tacomas is according to Rich and Carla Krajewski the only weapon they have to warn people about Toyota.

“They have the nerve to call their trucks bullet-proof. I think they're more like bullet-ridden. I am just very disappointed in Toyota,” said Carla.

She and her husband are afraid to drive their 1995 Toyota Tacoma. The frame is covered in rust and she said eventually the frame will fail.

“You cannot do anything about the internal rust,” said Rich.

Team 5 Investigates reported that the frame on their truck will fail and Toyota knows it.

Team 5 Investigates reported that Toyota admits more than 800,000 Tacoma trucks built between 1995 and 2000 did not have adequate corrosion protection, causing the frames to disintegrate from rust.

Toyota is buying trucks back at 150 percent of the Blue Book value, but not the Krajewskis' truck. They said Toyota says it's not bad enough yet.

“This is a classic case of knowing they have a problem, doing nothing and possibly someone gets seriously hurt,“ said Rich.

Toyota told Team 5 Investigates they won't do anything for drivers who junked their Tacomas before Toyota announced its buy-back program.

Consumers claimed they had trucks that were so damaged they couldn't drive them or get them fixed.

Patty and Paul Cormier have a new truck now. Their 1999 Tacoma failed a state inspection last fall because the frame was all rusted out.

“It couldn't be welded. It couldn't be fixed,” said Patty.

They had no choice but to junk it, just four months before Toyota announced the buy-back.

“They should reimburse us for whatever somebody who still has this same truck is getting,“ said Patty.

Rebecca Lindland, an industry expert who works for Global Insight, said that by refusing to buy back all the rusted trucks, Toyota risks losing its reputation for excellent customer service.

“It's going to do a lot of damage to that reputation that is going to be hard to get back,” said Lindland.
