A mere four days have gone by since Nissan last issued a recall of Infiniti vehicles. Now the car manufacturer is upping its game by making two recalls at the same time affecting nearly 16,000 vehicles with possible software and transmission issues.

A notice [PDF] from the National Highway Traffic Safety Administration states that Nissan initiated the recall of 14,438 model year 2014 Q50 and Q70 hybrid sedans because the electric motor may stop running.

The stall-like condition, which may increase the likelihood of a crash, could be the result of a communication error between the motor inverter and the transmission control module.

According to NHTSA, the stalling condition does not occur when the car is operating at highway speeds while the combustion engine is in use.

Officials with Nissan report that they became aware of the issue in August after a field incident in Japan.

Owners of affected vehicles will be notified of the issue and dealers will reprogram the motor inverter software at no cost.

Nissan’s second recall of the day involves 1,641 model year 2014 Infiniti Q50, A70 and Q70L hybrid sedans with possible transmission housing issues.

According to NHTSA documents [PDF], the vehicles have automatic transmission housing that may have cracks caused during manufacturing.

The car company says that over time the cracks could lead to larger fractures, producing on-road debris and increasing the chance of a crash.

To fix the issue, dealers will install a new transmission assembly if cracks are found. Owners of affected vehicles will be notified in mid-November.

Late last Friday, Nissan recalled 1,841 Infiniti vehicles over defective Takata airbags.
