An audit of the city's Access-A-Ride program shows a majority of complaints about the service don't even get investigated.

The audit examined more than 21,000 rider complaints made in 2016 and found that almost half remained unresolved.

Some of the complaints involve drivers going as fast as 80 mph in a 40 mph zone, threatening riders and not properly securing wheelchairs in vehicles.

Access-A-Ride is operated by the Metropolitan Transportation Authority, but is contracted outside to vendors that provide transit solutions for New Yorkers who have a disability that prevents them from using the public buses or subways.

The audit found that complaints from riders to the MTA were passed along to the contracted companies and were often never investigated further.

City Comptroller Scott Stringer initiated the audit and says he was astonished by the results.

Even people who don't use the service tell News 12 they're shocked about the findings.

Stringer has given the MTA a long list of recommendations to fix the complaints and has even suggested hiring someone to defend the public’s interest within the agency.
