2017 Infiniti QX70

When driving on the highway the car stopped changing gears and then flashed a check engine light, this has already happened to me on another QX70 infiniti that I had previously owned so it seems to be a common problem especially since Infiniti has now updated the part stamping to a G2A model from an MB3 since they know these parts fail. The car becomes undriveable on the road as gears stop shifting. This isn't something that is determined on how you drive but merely a sensor in the transmission that is prone to failing and creating an unsafe situation. I searched it online and it appears many people have problems with the transmission valve body failing on these poorly designed parts.

The contact owns a 2017 Infiniti QX70. The contact stated that while driving approximately 55 MPH, the transmission was hard shifting into gear. The contact stated that the transmission failed to shift into the proper gear. Additionally, while driving in the rain, the vehicle hydroplaned on three occasions. The check engine warning light was illuminated. The vehicle was taken to the local dealer where it was diagnosed that the valve body needed to be replaced. The battery was replaced. The vehicle was repaired but the failure recurred. The manufacturer was not contacted. The failure mileage was approximately 85,000.
