Tesla is in dispute with the normally electric car-friendly Norwegian government over setting up a mobile service van operation.

But, according to Reuters, Norway rejected a suggestion it was holding up Tesla's plans to improve service in its third-biggest market, saying the automaker had not yet applied to use the mobile service vans it says it needs to solve its problems.

The news agency noted Tesla chief executive Elon Musk last week blamed a wait for government approval for not being able to move faster in addressing growing complaints from consumers.

The Norwegian Consumer Council had said on 4 July 4 Tesla had climbed to fourth place in the first six months of 2018 in the list of companies Norwegians complain about the most, up from 24th in 2017.

According to Reuters, Musk tweeted in response: "Norwegians are right to be upset with Tesla. We are having trouble expanding our service facilities in Oslo especially. Can solve quickly with Tesla mobile service vans, but awaiting govt permission to do so."

But Norway's public roads authority said it had not yet seen a formal application from the company.

"Tesla Norway has recently been in a dialogue with the Norwegian Public Roads Administration (NPRA) about regulations for allowing workshops or the possibility of so-called 'mobile service vans'," the Norwegian transport ministry said in a statement to Reuters.

"The NPRA gave its answer on June 1, explained the rules that are valid and that they would welcome a potential application from Tesla Norway to allow mobile service vans. The NPRA has for the moment not received, as of today [6 July], such an application."

Tesla Norway told Reuters media queries should be handled by its European press office which was not immediately available for comment.
