Within a few weeks of purchasing our vehicle, we brought it back to the dealer due to violent shaking from the front end. We were told we needed 4 brand new tires. Buying new tires did not fix the problem. Within a few days we began to hear a humming, vibrating, and growling noise coming from the front of the vehicle when you hit approximately 40 mph. We brought the vehicle back to the dealer and brought the sales manager for a test drive to hear the noise. When my wife explained that she was scared to drive the vehicle, they assured her that it was not a safety hazard and the vehicle would be fine to drive. The service manager called and said they had to replace the free wheel valve solenoid. We picked up the truck and on our way home the noise returned. We called the service manager and explained that the noise was still there and we were to bring the vehicle in again and take the technician for a test drive in it so he can hear the noise. While on test drive the tech advised her that they had other Montero's that made the same noise and when they changed the sensor it went away. Then they said the "torque" converter was bad - they changed it but it didn't fix the problem, then they drained the transmission fluid, didn't fix the problem. Then we were told they might have to replace the entire drive shaft. They never changed the drive shaft but instead replaced the left hub bearing assembly. My wife picked up the vehicle 2 days later and the noise was gone but the engine was "jumping" every time she stopped at a red light. This has happened several times, but we keep getting told that the computer isn't showing any problems. Why has nothing been done about all the roll over cases we keep hearing about?
