2006 Mazda Tribute. Runs fine during warm weather. At the slightest outbreak of cold weather, accelerator does not depress, unable to get any power from the engine. Will freeze up at times while driving or not work at all. Has been doing this for years, Mazda refuses to acknowledge problem. Has almost caused numerous accidents when accelerating around a turn due to loss of power. Mazda has recalled previous model years for this problem but will not recall this model. Please change that.

After coming to a stop at an uphill grade--approx a 20 degree incline, as soon as the brake is released, the vehicle rolls backwards. The only means to prevent the vehicle from rolling back is to press on the brake again or to immediately press hard on the gas pedal. However, although the vehicle eventually starts moving uphill, there is a significant amount of backward travel prior to the engine producing enough power to overcome the backward roll. This is a safety concern since there might be vehicles directly behind me when this occurs. Fortunately, I have not had to stop at any steep grades that might cause the vehicle to rollback faster and further and possibly causing an accident.

Vehicle makes a loud high pitch whining noise when engine is around 1000 RPM but disappears when the engine is below or above the 1000 RPM. This occurs regardless of whether the car is parked or during normal driving conditions so long as the engine is around 1000rpm. In addition to the high pitch whining noise, there is a noticeable amount of vibration that is felt. Also, after coming to a full stop, without the gas pedal being pressed, after having revved down to about 650 RPM, the engine sometimes revs back up to about 1000 RPM and produce the whining noise.
