Nissan is recalling more than 809,000 small sport-utility vehicles in the United States and Canada because of a key problem that can cause the ignition to shut off while the vehicles are being driven.

The recall covers certain Rogues from the 2014 through 2020 model years and Rogue Sports from 2017 through 2022.

Nissan says the SUVs have jackknife folding keys that might not stay fully open. If driven with the key partially folded, a driver could touch the fob, inadvertently turning off the engine.

That can cause loss of engine power and power brakes, and the air bags might not inflate in a crash, according to the automaker, which says it’s not aware of any crashes or injuries caused by the problem.

Nissan hasn’t come up with a fix yet.

Owners will be notified in March with an interim letter telling them not to attach anything else to the key ring. Then, Nissan says, they’ll get another letter telling them to take their SUVs in for repairs.

The automaker says owners with keys that won’t stay in the open position should contact their dealer.
