NEW YORK (CBSNewYork) — Just one week into the new school year and hundreds of parents are complaining that a new GPS system that was supposed to keep track of all city school buses does not work.

On Thursday, CBS2’s Natalie Duddridge spoke to parents who said they were lied to.

Mother of two Lainie Gutterman meets her kids, 9-year-old Ian, who is autistic, and his sister, 6-year-old Greenly, who is non-verbal, at the bus stop. She said wondering where their school bus is every day is stressful.

“I was promised that there would be GPS, that I could see my children’s bus, where they were at all times, on my phone, which would be a great way to follow my kids,” Gutterman said.
