I believe the recall only applied to the '09 model year.

Likely it's either a misadjusted or damaged shift cable or park-neutral switch. Sorting out which is not really a DIY job but that, of course, depends on the DIYer.

#PIC5234: Intermittent No Crank No Start With No DTCs - (Sep 1, 2009)


Subject: Intermittent No Crank No Start with no DTCs


Models: 2008-2010 Chevrolet Malibu

2007-2010 Pontiac G6

2007-2010 Saturn Aura




--------------------------------------------------------------------------------

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

Condition/Concern:
Condition:
Intermittent No Crank No Start.

Cause:
A customer or technician may comment on the above condition. This could be the result of any of the following:

Misadjusted or damaged transmission shift cable. Park Neutral (PN) switch installation or internal failure. Loose or broken battery ground cable to ground stud (mostly on the 3.5L engine on the ground stud on the trans) Loose or damaged cable at the B+ post at the starter.

Follow the below steps to determine the root cause and necessary repair.

Recommendation/Instructions:
Carefully inspect transmission shift cable for any signs of damage. Replace cable if any damage is found.
Check transmission shifter and cable adjustment
In an attempt to duplicate the condition try shifting from any shifter position into the park position carefully, not slamming it in park. After shifting in to park try starting vehicle. If the vehicle does not start unless you push the shifter hard in to park you will need to adjust the shift cable as described (09077A)

Check output from Park Neutral switch to ECM for proper signal. Check all terminals for loose or poor connections at Park Neutral switch and ECM. If all appear okay replace the Park Neutral switch.
Loose or damaged nut/cable at the B+ post on the starter. (PIC5100) If post is damaged the starter will need to be replaced.
Loose battery ground at the ground stud. This issue is mostly been seen on the 3.5L engine, however some cases on 4 cylinder also. Check for loose connection between terminal and stud. Check for poor crimp between the terminal end and the cable. Check for broken cable strands at the crimp which may create high resistance. Replace the ground cable if a poor crimp is found or the cable has any sign of damage. If fastener is loose tighten fastener to proper torque.
Poor terminal connection at ECM or UBEC. Remove and do a terminal inspection and lube as per TSB (08-05-22-009A)
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.

That is not to say there isn't a problem with other model years but there are no other recalls on G6 shifter cables. There were two recalls for '05 models, neither involved the shifter.

NEWS: Regulators probing gear shift trouble with GM cars

YAHOO NEWS -- November 14, 2011 – Federal safety regulators are investigating problems with the automatic shift levers on several General Motors cars because drivers may think the cars are in park when they actually are in gear.

Seven crashes have been reported because of the problem, including one in which a driver put a car in park, got out and was struck and injured when the car unexpectedly rolled backward, the National Highway Traffic Safety Administration said Monday in documents posted on its website.

Another car put in park with the engine running reportedly accelerated and ran into a wall after the driver got out.

NHTSA said the protective jacket around cables connecting the floor shift lever to the transmission can deteriorate, exposing the cables to the elements. Cables can corrode and weaken, and the shift lever position can change so it doesn't match the car's gear. That means a driver could put the car in park but the transmission could be in drive or reverse. In some cases, the car may not shift at all.

The probe began with complaints about the Saturn Aura midsize car from the 2007 and 2008 model years, affecting nearly 89,000 vehicles. But the agency said it is now checking to see if the problems extend to other GM vehicles. The Chevrolet Malibu from the 2004 to 2008 model years and the Pontiac G6 from the 2005 to 2008 model years have similar shifting systems, the agency said.

NHTSA said it received three reports of crashes caused by the problem, while GM received four, including the one that injured the driver. No details were given on whether the driver was seriously hurt.

In another case, a driver put the car in park, but the transmission stayed in reverse. "When the driver exited with the engine running, the vehicle continued (accelerated) in reverse and struck a building," NHTSA said.

GM told the agency that the problem affects mainly models with four-speed transmissions, but not six-speed transmissions.

NHTSA said it has upgraded the investigation to an analysis that will check how many times the cables have failed, the consequences "and the scope of vehicles that may be affected, including the models, model years and transmission types."

An investigation doesn't necessarily mean that the vehicles will be recalled.

Company spokesman ...said GM is cooperating in the investigation. The company will make free shifter cable repairs on affected 2007 and 2008 Auras, and it will cover the repairs for 10 years or 120,000 miles from the date the original owner picked up the car. Those who already have paid for repairs should keep receipts for reimbursement, Company spokesman said.

Although the Malibu and G6 have similar shift systems, the problem happens far less frequently on those cars than it does on the Aura, Company spokesman said. The same parts maker supplied cables for all three vehicles, but the Malibu and G6 cables are not exactly like the Aura's, he said.

Anyone who has an issue with shifting should contact a GM dealer. GM got rid of the Saturn and Pontiac brands last year, and other dealers, mainly Chevrolet, became their authorized repair centers.

GM sold more than 815,000 Chevy Malibus in calendar years 2004 through 2008 and over 570,000 Pontiac G6 models from 2005 through 2008, according to Autodata Corp. and Ward's AutoInfoBank. It's unlikely that all of those cars will be covered by the investigation because they have several types of transmissions.

In March of 2009, GM recalled about 277,000 vehicles for a similar shift lever problem, although NHTSA documents say that was caused by a faulty clip used to adjust the cable.

At that time the recall involved 2009 model year versions of the Buick Enclave; Chevrolet Cobalt, HHR, Malibu and Traverse; GMC Acadia; Pontiac G5 and G6; and the Saturn Aura and Outlook. Only 75,000 of the vehicles had been sold, and the rest were still at dealerships.
