The Mountain View School Division is having a problem with their school buses.

Bart Michaleski says the problem is with some of the engines being worn out.

The problem occurred with the company's engine technology, to deal with emissions, the engine recirculated the exhaust back through the engine to clean the emissions. In turn, it actually wore out the engines, causing them to fail.

After 2014, the company abandoned that technology.

Michaleski says the buses only have a 10-year warranty and they hope the buses will last 17 years.

The seven buses from 2012-14 are the ones in question.

Some of those buses have had their engines replaced up to 3 times now.

They will be dealing with this problem for at least the next 6 years.

Once the warranty for the engines is up, it would cost between 35000-40000 dollars.

It doesn’t make sense to pay that cost once the warranty is up so they’d likely just look into getting new buses.
