Polaris Industries issued its 11th recall of the year this week, one involving 2,800 Scrambler vehicles because of possible throttle-switch problems that could lead to a crash.

The latest recall affects Scrambler XP 1000 models from 2014 and 2017. The Consumer Protection Safety Commission reported that Polaris received nine complaints from customers about throttle problems, two of which involved minor injuries.

Vehicle owners are told not to ride the $13,300 machines but instead to bring them into dealerships for a free repair.

With this week's recall, Polaris has recalled more than 420,000 machines in the past two-and-a-half years because of mechanical or fire problems.

While Polaris has launched engineering and investigative teams into the field to find, fix, study and prevent possible problems, mechanical issues, fires and recall woes keep dogging the Medina-based manufacturer.

Three weeks ago, Polaris issued two recalls — one for 25,760 Sportsman vehicles and the other for 1,160 of its 2017 RZR 570 models. It received 30 reports from Sportsman customers about fuel leaking into headlights and four reports about fires. Polaris' internal review process discovered front brake problems in its RZR 570 models. No injuries were reported in that instance.

On July 27, however, Polaris was sued by Colby Thompson after a fire allegedly occurred on July 23 in the Polaris RZR he was riding in Bozeman, Mont. Thompson suffered third-degree burns on both arms and second-degree burns to his face, head and neck, according to the complaint. The lawsuit is the latest of several filed by victims or their family members following fires and injuries.

Polaris officials on Wednesday declined to comment about the recalls or the lawsuit.

Polaris' stock rose 19 cents a share to close at $88.67 per share Wednesday. The stock has fallen from the year-ago price of $98.66. It is down from the $138 per-share price reported two years ago.
