| Description of the problem | 1. Cruise control device on my 1996 toyota sienna has been behaving erratically since about 2 months. It has over 45000 miles on the odometer and is thus out of warranty. 2. Mechanically there does not appear to be any defect. However the following anomalies are being observed during the past 2 months. A: 90% of the time in speeds in excess of 50 mph, when i try to set the cruising speed by pressing the ccl (cruise control lever) downwards, nothing happens. In more than 50% of these times, if i lift the ccl upwards (normally the method to re-set cruising speed after braking/slowing down) the cruising speed gets set. B. Under conditions as in 'a' above many of the operations of the ccl appears to happen in an inverted manner, like setting instead of re-setting, re-setting instead of setting, etc. 3. It appears there is something definitely wrong with the electronics of the cruise control system, and while this has not happened so far, may in fact, cause unwarranted de-celeration/acceleration, and could cause accidents. 4. It is emphasized that these anomalies have *** not *** caused any accident yet. This vehicle is *** not *** included in any unexpected acceleration-related recalls. But this behavior of the cruise control may have something to do with unusual accelerations. |
