Well this isn’t good. Took the car on an 800 mile trip and the steering was wandering to the point it was scary to drive. Took it to the Infiniti dealer in the city I was visiting and they said they could find nothing wrong with the steering but there was a massive coolant leak. The Infiniti tech line had seen this before and apparently the only fix was a replacement engine. Car has been tied up for a month. Anybody else come across this ?
