THE CAR WON'T GO FORWARD OR REVERSE. DEALER NOW PUTTING IN A NEW TRANSMISSION AT $3000. VERY SCARY SITUATION AND NOW THAT I HAVE GONE ONLINE AND SEEN HOW MANY OTHER SATURN AURO'S HAD TO REPLACE TRANSMISSIONS I DON'T UNDERSTAND WHY GM HASN'T HAD A RECALL/REIMBURSEMENT. THEY OBVIOUSLY KNOW THAT THERE IS A PROBLEM. I HAVE HAD TO TAKE A LOAN OUT AT THE BANK TO PAY FOR THIS. THANK GOD MY 15 YEAR OLD DAUGHTER HASN'T STARTED DRIVING IT YET. *TR

I EXPERIENCED THE SAME ISSUE AS A LOT OF OTHER OWNERS, THE GEAR SHIFT WOULD NOT GO INTO PARK SO THEREFORE MY CAR STARTED TO ROLL AWAY. AFTER SEVERAL ATTEMPTS I WAS STILL NOT ABLE TO GET IT IN PARK SO I LEFT IT IN NEUTRAL AND PUT ON THE EMERGENCY BRAKE. TO START MY VEHICLE I HAVE TO HAVE MY CAR IN NEUTRAL OR ELSE IT WILL NOT START. I RESEARCHED THE ISSUE AND SAW THAT THIS WAS AN APPARENT ISSUE THAT SEVERAL OWNERS HAVE SEEN SO I CALLED GM TO GET SOME INFORMATION. THE LADY THAT ANSWERED THE PHONE HAD A HEAVY ACCENT AND IT WAS VERY DIFFICULT TO UNDERSTAND HER BUT SHE STARTED A CASE AND TOLD ME TO TAKE MY CAR TO THE LOCAL AUTHORIZED SATURN REPAIR FACILITY. THE SERVICE TECHNICIAN INVESTIGATED THE ISSUE AND DETERMINED THAT THIS PROBLEM WAS INDEED THE EXACT ISSUES THAT THE RECALL WAS TO ADDRESS, THE GM SERVICE REPRESENTATIVE WAS NOTIFIED AND THEY REFUSED TO AUTHORIZE THE DEALER TO PROCEED WITH THE REPAIR. HER REASON WAS THAT THE CAR HAD TOO MANY MILES AND THAT THE CABLE BROKE BECAUSE OF NORMAL WEAR AND TEAR. THE DEALER INFORMED ME THAT IT WOULD BE CLOSE TO $600 TO REPAIR MY CAR AND AT THE POINT, I INFORMED THEM NOT TO DO THE REPAIR DUE TO LACK OF FUNDS ON MY PART. I AM STILL DRIVING THIS CAR WITH THIS PROBLEM, I JUST HAVE TO REMEMBER TO ALWAYS ENGAGE MY EMERGENCY BRAKE AFTER SHUTTING OF MY CAR. I'M SO GLAD THAT OUR GOVERNMENT AGREED TO BAIL OUT GM AND THEN HAVE THEM OUTSOURCE THEIR CALL CENTER AND REFUSE TO HONOR THEIR RECALLS, GREAT MOVE. UPDATED 6/13/13 *CN INVOICE RECEIVED.

ON FRIDAY, MAY 17TH THE VEHICLE WAS DRIVEN AND DROVE NORMALLY ON MONDAY, MAY 20TH THE CAR WILL NOT GO INTO REVERSE AND WILL NOT GO FORWARD. IT WAS TOWED TO A MECHANIC AS IT WAS COMPLETELY UNABLE TO BE DRIVEN. MECHANIC INDICATED THAT THE TRANSMISSION WAS NOT OPERATING AND TRYING TO ENGAGE THREE GEARS AT ONCE. I CALLED A LOCAL TRANSMISSION SHOP AND THEY INDICATED THIS IS A COMMON WITH THE ENGINE/TRANSMISSION IN THIS VEHICLE. ESTIMATE IS $2,800 TO $3,000 TO HAVE THE TRANSMISSION REBUILT. THE VEHICLE ONLY HAS 92,000 MILES. I CAN ONLY IMAGINE WHAT WOULD HAVE HAPPENED IF IT HAD THIS SUDDENLY WHILE DRIVING IN TRAFFIC. *TR
ALL OF SUDDEN THE VEHICLE LOST POWER. THE TRACTION LIGHT AND CHECK ENGINE LIGHT CAME ON. THEN THE VEHICLE READ LOST OF ENGINE POWER ON THE SCREEN. THIS APPEARS TO BE HAPPENING A LOT WITH SATURN VEHICLES WITH AS VIEW AS 25,000 MILES OF THEM. *TR

May 14, 2014
General Motors LLC (GM) is recalling certain model year 2004-2012 Chevrolet Malibu vehicles manufactured May 16, 2003, through October 11, 2012, 2004-2007 Malibu Maxx vehicles manufactured June 25, 2003, through April 5, 2007, 2005-2010 Pontiac G6 vehicles manufactured May 26, 2004, through January 4, 2010, and 2007-2010 Saturn Aura vehicles manufactured April 24, 2006, through May 26, 2009. In the affected vehicles, increased resistance in the Body Control Module (BCM) connection may result in voltage fluctuations in the Brake Apply Sensor (BAS) circuit. These fluctuations can cause one or more of these conditions: the brake lights to illuminate without the brake pedal being pushed; the brake lights to not illuminate when the pedal is pushed; difficulty disengaging the cruise control; moving the gear shifter out of the 'PARK' position without pushing the brake; and disablement of crash avoidance features such as traction control, electronic stability control, and panic braking assist features.
Consequence & remedy
Consequence: Any of the above failure conditions increases the risk of a crash.
Remedy: GM will notify owners, and dealers will attach the wiring harness to the BCM with a spacer, apply dielectric lubricant to both the BCM and harness connector and the BAS and harness connector, and will relearn the brake pedal home position, free of charge. The manufacturer distributed an Interim letter to customers on July 14, 2014. The recall began on August 18, 2014. Owners may contact General Motors customer service at 1-800-222-1020 (Chevrolet), 1-800-762-2737 (Pontiac), 1-800-553-6000 (Saturn). GM's number for this recall is 13036.

14V224000 · Power Train:automatic Transmission; Power Train:automatic Transmission:lever And Linkage:floor Shift
Apr 30, 2014
General Motors LLC (GM) notified the agency on April 29, 2014, that they are recalling 56,214 model year 2007 and 2008 Saturn Aura vehicles. On May 22, 2014, GM increased the recall to include an additional 1,074,899 model year 2004-2008 Chevrolet Malibu vehicles manufactured from May 16, 2003, through October 5, 2007, model year 2004-2007 Malibu Maxx vehicles manufactured from June 25, 2003, through April 5, 2007, and model year 2005-2008 Pontiac G6 vehicles manufactured from May 26, 2004, through September 28, 2007, and equipped with 4-speed transmissions. The total number vehicles being recalled is now 1,131,113.
Consequence & remedy
Consequence: If the transmission shift cable fractures while the vehicle is being driven, the transmission gear selection may not match the indicated gear and the vehicle may move in an unintended or unexpected direction, increasing the risk of a crash. Furthermore, when the driver goes to stop and park the vehicle, despite selecting the PARK position, the transmission may not be in PARK. If the vehicle is not in the "PARK" position there is a risk the vehicle will roll away as the driver and other occupants exit the vehicle or anytime thereafter. A vehicle rollaway increases the risk of injury to exiting occupants and bystanders.
Remedy: GM will notify owners, and GM dealers will replace the shift cable assembly and mounting bracket, free of charge. The manufacturer has not yet provided a notification schedule. Owners may contact General Motors at 1-800-553-6000. GM's number for this recall is 14152.

12V460000 · Power Train:automatic Transmission:gear Position Indication (prndl)
Sep 18, 2012
General Motors (GM) is recalling certain model year 2007-2010 Saturn Aura and model year 2008-2010 Chevrolet Malibu and Pontiac G6 vehicles, equipped with a 4-speed automatic transmission. On these vehicles, the tabs on the transmission shift cable end may fracture and separate.
Consequence & remedy
Consequence: If the tabs were to fracture and separate, the shift lever and the actual position of the transmission gear may not match. The driver would be able to move the shifter to 'PARK' and remove the ignition key, but the transmission gear may not be in 'PARK.' The vehicle may not be able to be restarted and the vehicle could roll away after the driver has exited the vehicle, resulting in a possible crash without prior warning.
Remedy: GM will notify owners, and dealers will install a retainer over the cable end or replace the shift cable as necessary. This service will be performed free of charge. Notification to owners began on on November 9, 2012. Owners were instructed to not bring their vehicles for repair until January 2013. Owners may contact General Motors at 1-800-521-7300.

Opened Nov 10, 2011 · Closed Jun 2, 2014

On April 29, 2014, GM submitted a Part 573 defect information report initiating Safety Recall 14V-224 to remedy the subject vehicles equipped with four speed automatic transmissions manufactured before October 31, 2007.On May 22, 2014 GM expanded 14V-224 to include MY 2004-2008 Chevrolet Malibu/Malibu Maxx and MY 2005 - 2008 Pontiac G6 (total recall population 1,131,113).GM will install a replacement shift cable assembly to remedy the affected vehicles.The subject shift cable's protective outer conduit (jacket) deteriorates with time and use.Jacket deterioration could lead to a tear of the conduit material which allows moisture to reach the lay wires, potentially causing them to corrode and weaken.The lay wires provide support to the inner core wire that performs the shift detent actuation of the transmission.Without sufficient lay wire support, the shifter position inside the vehicle and the actual transmission gear selection may not align.A complete loss of shift function can occur when the core wire fractures and fails fully.The failure data supports that the problem affects subject vehicles equipped with four-speed automatic transmissions. Aura vehicles manufactured with other transmission types use a different shift cable assembly, as do four speed equipped Aura's manufactured after October 31, 2007.Transmission shift cable failure can cause multiple shift function failure modes.One involves an engine no-start condition where the gear shifter is in the park position but the transmission is actually in drive or reverse gear (engine starting is inhibited in this circumstance).A second involves non-powered vehicle movement where the driver turns the engine off and moves the shifter to park but the transmission fails to engage the park gear; the vehicle may roll away if the driver exits without setting the park brake.A third involves powered vehicle movements, where the driver moves the gearshift but the transmission fails to engage the intended gear, and the engine remains running.For instance the driver can shift to park but the transmission may remain in drive or reverse, resulting in vehicle movement when the driver does not expect it.Another failure involves the driver shifting to reverse but the transmission remains in drive, resulting in the vehicle moving in a direction opposite to that the driver intended.Another failure mode results in complete loss of shifting.Both NHTSA and GM have received complaints alleging one or more of these failure scenarios, and in some cases consumers report experiencing multiple problems over the course of several drive cycles.In one incident, the vehicle unexpectedly moved forward after the driver placed the gear selector in park resulting in the vehicle striking a fixed object (porch railing).Among the crashes identified above, nine involved property damage and two involved minor injuries when the vehicles rolled and struck the driver as they exited the vehicle.The recall action initiated by the manufacturer appears to address the safety risks of concern to ODI.Accordingly, the investigation is closed.The VOQs cited above can be viewed at www-odi.nhtsa.dot.gov/owners/SearchNHTSAID under the following identification numbers: 10274914, 10404010, 10432953, 10446285, 10458417, 10495979, 10547333, 10354195 , 10404496, 10435560, 10447211, 10461922, 10498567, 10547683, 10374834, 10405577, 10435633, 10447303, 10464207, 10513116, 10553840, 10378975, 10409341, 10435653, 10449759, 10464388, 10513875, 10554335, 10382559, 10411913, 10435677, 10452089, 10467958, 10516001, 10565628, 10383044, 10412157, 10435996, 10452662, 10478887, 10522732, 10566451, 1039013

GM advised that the shift cable's protective outer conduit (jacket) deteriorates with time and use.Variables that affect jacket life include installation variability (routing, etc), environmental and temperature effects, and material quality.Jacket deterioration could lead to a tear of the conduit material which allows moisture to reach the lay wires, potentially causing them to corrode and weaken.The lay wires provide support to the inner core wire that performs the shift detent actuation of the transmission.Without sufficient lay wire support, the shifter position inside the vehicle and the actual transmission gear selection may not match.A complete loss of shift function can occur when the core wire fractures and fails fully.GM asserts that the problem primarily affects the four-speed equipped subject vehicles, but not the six-speed transmissions, and notes that similar cable installations are used in other model and MY GM vehicles (2004-2008 Chevrolet Malibu and 2005-2008 Pontiac G6). In reviewing consumer reports ODI notes multiple failure modes that occur as the cable allegedly fails and shift function is affected.One involves an engine no-start condition where the gear shifter is in the park position but the transmission is actually in drive or reverse gear (engine starting is inhibited in this circumstance).A second involves non-powered vehicle movement where the driver turns the engine off and moves the shifter to park but the transmission fails to engage the park gear; the vehicle may roll away if the driver exits without setting the park brake.A third involves powered vehicle movements, where the driver moves the gearshift but the transmission fails to engage the intended gear, and the engine remains running.For instance the driver can shift to park but the transmission may remain in drive or reverse, resulting in vehicle movement when the driver does not expect it.Or the driver may shift to reverse but the transmission remains in drive, resulting in the vehicle moving in a direction opposite to that the driver intended.Another failure mode results in complete loss of shifting.
