CHECK ENGINE LIGHT CAME ON. TWO MONTHS BEFORE INCIDENT, CAR WOULD GO INTO MANUAL SHIFT MODE AND THEN SHIFT BACK TO NORMAL MODE. IT WOULD ALSO SLIP GEARS AND AT TIMES THE REVERSE GEAR WOULD NOT WORK. THE CAR IS EQUIPPED WITH THE MANUAL PADDLE SHIFTERS. AT THE TIME OF THE INCIDENT, THE CAR COMPLETELY STALLED WHILE APPROACHING AN INTERSECTION AND THE SHIFTER WOULD NOT RESPOND TO ANY GEAR WHEN MOVED. THE CAR LOST COMPLETE POWER. THE CAR WAS TAKEN TO SEARS AND THE CODES P0716 (TURBINE INPUT SHAFT) AND P0700 (TRANSMISSION CONTROL SYSTEM) APPEARED. SEARS RECOMMENDED TAKING IT TO A DEALERSHIP. THE CAR WAS TAKEN TO FAULKNER CHEVROLET IN LANCASTER, PA. CHEVROLET RAN THROUGH COMPUTER AND FOUND SAME CODES. TECHS DRAINED TRANSMISSION FLUID AND FOUND METAL IN THE FLUID. A NEW TRANSMISSION WAS INSTALLED A COUPLE OF DAYS LATER. I CALLED GM TO REPORT THE PROBLEM AND THEY RESPONDED WITH RE-IMBURSING ME FOR A PORTION OF THE COST OF THE TRANSMISSION ($1,350 OUT OF $4,158.38). THE REP ON THE LINE SAID THAT WAS ALL THAT I WAS GOING TO GET AND THERE WAS NO POINT IN TRYING TO GET RE-IMBURSED FOR MORE. A SEARCH OF THE INTERNET FOUND SIMILAR PROBLEMS AND IT WAS MENTIONED THAT IT COULD BE RELATED TO THE WAVE PLATE. *TR

I'VE BEEN HAVING PROBLEMS SHIFTING FROM PARK TO REVERSE. THE CAR WOULD JOLT WHEN I PUT IT IN REVERSE, I HAD THIS PROBLEM FOR 2 MONTHS BEFORE THE INCIDENT HAPPENED. I WAS DRIVING ON THE FREEWAY MY CAR SLOWED TO ABOUT 15-20 MPH AND WAS NOT ACCELERATING ANYMORE, IT WAS MAKING A LOUD SOUND. I ALMOST CAUSED AN ACCIDENT BECAUSE OF THE SUDDEN SPEED DECREASE. I PULLED OFF THE FREEWAY AND MY CAR WOULDNT GO PAST 20 MPH WITHOUT THIS LOUD SOUND AND WOULD ALSO NOT GO IN REVERSE, SO I PULLED OVER AND HAD IT TOWED TO A LOCAL AUTO SHOP. THE MECHANIC TOLD ME MY TRANSMISSION WENT OUT AND WOULD NEED A NEW TRANSMISSION FOR $3800K. MY CAR IS ONLY 7 YEARS OLD AND HAS 64K MILES. I SHOULD NOT BE HAVING THIS ISSUE. *JS

TL* THE CONTACT OWNS A 2007 SATURN AURA. THE CONTACT STATED THAT THE VEHICLE WOULD NOT SHIFT INTO REVERSE. ALSO, WHEN THE GEAR WAS IN DRIVE , THE VEHICLE WOULD NOT ACCELERATE OVER 5 MPH. THE VEHICLE WAS TAKEN TO THE DEALER, BUT THEY HAD NOT YET PROVIDED THE DIAGNOSTIC RESULTS. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 73,000. THE CONSUMER STATED THE TRANSMISSION HAD TO BE REPLACED ON THIS VEHICLE, WHICH ONLY HAD 73,000 MILES. SHE CONTACTED THE MANUFACTURER SEVERAL TIMES REGARDING THE PROBLEM, AND THAT WAS HOW SHE FOUND OUT ABOUT THE EXTENDED WARRANTY. GM ISSUED EXTENDED WARRANTIES, ON 4 CYLINDER MODELS, BUT NOT 6 CYLINDERS MODELS. THE CONSUMER BELIEVED THAT WAS UNFAIR, BECAUSE HER VEHICLE HAD THE SAME PROBLEM. GM, DID OFFER ASSISTANCE OF $800 TO GET THE VEHICLE FIXED, BUT THE CONSUMER FELT SHE SHOULD NOT HAVE TO ABSORB THE BALANCE OF $ 3168.25. UPDATED 06/23/14 UPDATED 08/14/14*LJ UPDATED 8/28/2017*CN

MY SATURN STOPPED PULLING WHEN STOPPED, THANKFULLY AT OUR DRIVEWAY. IT WOULD NOT GO FORWARD AND THE ENGINE JUST REVVED. IT WOULD PULL IN REVERSE BUT NOT IN DRIVE. ATTEMPTED THE MANUAL MODE BUT STILL DID NOT PULL AND DID NOT SHOW GEAR INDICATION ON DASH. UPON SEVERAL TIMES TURNING ON AND OFF IT STARTED PULLING. THE DEALERSHIP COULD NOT RECREATE. PROGRAM UPDATE TO TCM AND $300 LATER WE LEFT. ONE MONTH LATER THE TRANSMISSION SLIPPING SO BAD IT ALMOST STALLED IN INTERSECTIONS CREATING A POTENTIALLY DANGEROUS SCENARIO. WE TOOK IT TO THE DEALERSHIP THE NEXT DAY TO HAVE THEM SAY WE NEED A NEW TRANSMISSION. THE DEALERSHIP WAS UNAWARE OF A RECALL ON THE NEWS REGARDING A TRANSMISSION PROBLEM FOR THE AURAS BUT NOT FOR THIS PROBLEM OR MODEL. THIS NEEDS TO BE A RECALL SINCE IT IS A SAFETY HAZARD. PLEASE CONSIDER A RECALL FOR THIS PROBLEM. *TR

MY CHECK ENGINE LIGHT CAME ON MONDAY (3/24/2014), SO I DROVE IT TO MY PARENTS HOUSE AFTER WORK THAT DAY. MY FATHER DROVE IT TO A REPAIR SHOP ON WEDNESDAY (3/26/14). ON THE WAY TO THE REPAIR JOB, THE CAR STOPPED CHANGING GEARS, AND SLOWED TO A STOP. HE LET IT REST FOR 10 MINUTES, THEN STARTED IT UP AND BEGAN DRIVING AGAIN. AFTER A FEW MILES, THE CAR ONCE AGAIN SUDDENLY SLOWED TO A STOP. HE LET IT REST FOR 10 MINUTES AGAIN, AND WAS THEN ABLE TO MAKE IT TO THE REPAIR SHOP. THE REPAIR SHOP INFORMED US THAT THE TRANSMISSION WAS COMPLETELY SHOT. THERE WERE CHEWED UP METAL SHAVINGS, PRESUMABLY FROM THE WAVE PLATE. THE TRANSMISSION MUST BE REPLACED. MANY PEOPLE HAVE EXPERIENCED THIS SAME PROBLEM ACCORDING TO EDMUNDS.COM, HOWEVER, GM HAS FAILED TO ISSUE A RECALL OR REFUNDS FOR REPAIRS. *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.

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
