The nissan maxima has been taken to the maintenance facility regarding an issue with the tires consistently losing air pressure. four new tires were placed on the vehicle at the nissan dealer and the same problem exists. we recently drove to the end of our driveway for distance travel and the tires locked, skidded and sounded as if metal was touching metal. we parked the vehicle and had to take other means of transportation. each time we take the vehicle into the nissan dealer for this and similar complaints, we're told it may be the weather, or that the tire pressure light which stays on may be due to a defective fuse, but that was no guarantee that the tire issue would be resolved. we get different possibility issues each time we go in. we hesitate to drive the vehicle for possibility of being stranded alongside a highway. we're making payments on an expensive 'paper weight.' the tire pressure light stays on, and even after putting air in the tires, the tires themselves still pose a problem. this recent incident has put the vehicle out of use until the nissan maintenance facility can give us answers as to what's really going on with the vehicle. needless to say, we have to pay for them to do anything other than put air in the tires, and after quoting large amounts of money for what may "possibly' be the problem, we may still drive away with the issue. this problem has been ongoing for over 1 1/2 years. the most recent incident is indicated below.
