State revenue officials say Kansas will not pay the final 10% of its contract for a new $40 million motor vehicle system until problems are fixed.

The Kansas Department of Revenue notified the 3M Co. Thursday that it needs to improve the new software, which has caused long lines and frustration at motor vehicle offices across the state since it was installed seven weeks ago.

Donna Shelite, the state director of vehicles, told the Shawnee County Commission that as many as 73,000 records didn’t convert correctly to the new system.

The Topeka Capital-Journal reports Shelite told the commission that Kansas officials have asked 3M to address the system’s response times, availability, bugs and maintenance.
