NHTSA Complaint #10428141 — 2007 PONTIAC G6

CRUISE CONTROL WAS ACTIVE-ON; WINDSHIELD WIPER WAS ON 'FAST PULSE'; RAIN WAS MODERATE TO HEAVY; ROAD WAS HILLY; EVENT: WHEN THE CRUISE NEEDED TO DECIDE TO SHIFT GEARS GOING UP A HILL THE WIPERS STOPPED LONG ENOUGH FOR THE RAIN TO OBSCURE ALL VISION. THE STOPPING WAS REPEATABLE BY SETTING UP SIMILAR SETTINGS WHEN THE RAIN/ROAD CONDITIONS ALLOWED. THIS CONDITION EVEN OCCURRED AT 35 MPH, WITH CRUISE ON, WITH WIPER FAST PULSE IN LIGHT RAIN, AGAIN OBSCURING FORWARD VISION, ON A MUCH LESS HILLY TERRAIN. DISCUSSIONS WITH GM AT THE TIME RESULTED IN THE STATEMENT THAT BECAUSE GM OR THE DEALER COULD NOT 'OBSERVE' THE 'STOPPAGE' THAT 'IT DID NOT OCCUR.' SEVERAL ATTEMPTS WERE MADE TO GET THE INFORMATION TO THE APPROPRIATE INTERNAL GM GROUP BUT NONE RESPONDED. SINCE THE CONDITION OCCURRED BOTH IN HILLY/MOUNTAIN TERRAIN AND IN HILLY CITY TERRAIN IT SEEMS THAT IT WOULD BE AN IMPORTANT ISSUE TO RESOLVE -- DUE TO THE LACK OF FORWARD VISION AT THE TIME OF OCCURRENCE. *TR
