| Description of the problem | My vehicle's cruise control (cc) lever has functions like; on-off, accelerate, decelerate, set, resume, cancel. The speed is set to the desired values by pressing the lever up (accelerate) and down (decelerate). When the lever is released to its neutral position, the set speed is maintained until the next interruption. To deactivate the cc without erasing the set speed, driver has to tap on the brake pedal or pull the cc lever toward himself. In order to erase the set speed and deactivate the cc at the same time, the driver has to switch the cc to off position. The nonconformity regarding my vehicle's cc system is unintended deactivation of cc without pulling the lever toward myself or tapping the brake pedal. The unintended deactivation occurs without any warning. Deactivation can only be realized if i, somehow, notice that the vehicle slows down by itself or pressing the lever up becomes non operative. This problem does not occur if i press the cc lever up and down with rapid moves, but if i move the lever up slowly or if i hesitate to accelerate the vehicle for even less then a second and hold the cc lever at a position between the "neutral" and "accelerate", it happens all the time. When it occurs, any attempt to accelerate the vehicle by using the cc lever is vein, unless you realize the situation and reactivate the cc system again. Other than the unintentional slow down of the vehicle without any warning, an other consequence of this nonconformity is the uncontrolled acceleration of the vehicle up to it's previous set speed. When the driver realizes the situation and reactivates the cc, the vehicle comes to the previous set speed almost with a full throttle acceleration. I have informed the local dealer and the authorized service department about the situation but they have claimed that it was my fault to move the lever slowly and move it with hesitations. |
