The unique pick up and drop off car rental service started with a bang in Calgary six months ago, but many of its customers are now complaining of poor service.

People who’ve paid for the service and have even made reservations now say the Car2Go vehicles, blue and white Smart cars parked in specific zones throughout the city, aren’t reading their access cards anymore.

The problem seems to be focused on one area, but there are reports of similar issues with vehicles in other areas.

Loy Bartusek joined the service a couple of months ago and she was thrilled with the prospect of using the cars whenever she wanted and dropping them off at her destination.

There are about 200 to 300 of the vehicles in the community of Connaught where she lives.

“I would just hop in the car, I would go buy groceries, I would zip over to my friend’s house,” she says.

For the past several weeks, Bartusek has found that the cars are no longer reading her access card.

She says it appears the car is trying to connect with the system’s network, but nothing happens.

There is also a car on her street that looks to be completely drained of power.

Car2Go has acknowledged there’s a problem to it’s Twitter users and is working to fix it.

Bartusek says that it is time for the company to start paying for the service that they can’t use.

“”What is the problem? It’s the only one in this area and it’s been a month now? So why? Why is it taking so long?”

Erin, another Car2Go customer says that the vehicles issues are affecting her community of Kensington too.

“Easily before the holidays, there has been a car sitting there, with an out of service message on the dashboard.”

She says that she wants answers and an apology from the company. “I really just think that if they just kinda stepped back and apologized to the customers, to all the inconvenience they’ve caused over the holidays, and acknowledge there’s been a major problem, I think they could win back, conceivably win back, their customers.”

Car2Go hasn’t responded to numerous calls and e-mails placed over the holidays, but their customers say that the holidays are busy for them too and they’ve needed the service they’re paying for, but can’t use.
