Washington -- Chrysler Group LLC said Friday it will recall more than 1,200 2013 heavy-duty Ram pickups to fix a headlight software glitch -- the company's sixth recall campaign in the last two weeks.

The Auburn Hills automaker said it is recalling more than 1,200 Ram 2500 and 3500 trucks to ensure their headlights comply with regulations when in high-beam mode.

An internal investigation by Chrysler engineers discovered some vehicles were assembled with headlamps whose high beams do not comply with standards governing aim and intensity. Chrysler will update the software that controls headlamp function. The automaker is unaware of any associated accidents injuries or complaints.

The recall is limited to some 2013 Ram 2500 and 3500 trucks equipped with premium headlamps. Approximately 1,100 are in the U.S., 170 are in Canada and 15 are outside North America, Chrysler said.

This is the latest recall to reprogram Chrysler software. Chrysler is also recalling 14,800 2013 Dodge Dart cars to recalibrate powertrain software to address stalling complaints.

Chrysler spokesman Eric Mayne said the company's investigation turned up 85 field reports of similar incidents from dealers -- though it is unclear how many are related to the recalibration issue. Chrysler is unaware of any related injuries or accidents. Chrysler dealers will recalibrate powertrain control modules.

The recall affects only 2013 Dodge Dart models with a 1.4-liter engine and dual-clutch transmission.

Meanwhile, this is the third recall for some 2013 Ram pickups announced this week. On Thursday, Chrysler said it would repair 37,000 Ram pickups.

The Auburn Hills automaker said Thursday it is recalling 30,000 2013 Ram 1500, 2500 and 3500 pickups to upgrade software to fix the tail-lamp warning light.

Chrysler said if a tail-lamp is not functioning properly, the trucks are to alert drivers with an instrument-panel warning light. Chrysler dealers will perform a software upgrade to reactivate the warning light, which is a mandated safety feature. The tail lights are not impacted by the recall, which includes 17,400 in the United States and 13,000 elsewhere.

The issue was discovered by Chrysler engineers performing routine testing.

Chrysler issued a separate recall of 6,900 heavy-duty trucks to prevent front axle damage. Following reports that two trucks had sustained damage, Chrysler discovered some trucks were subject to a condition that may cause the front prop shaft to bind or fracture, resulting in power loss. The recall covers 5,600 2012 Ram 4500 and 5500 trucks in the United States, and 1,300 in Canada.

Last week, Chrysler said it was recalling more than 620,000 Jeep vehicles for air bag and power steering issues.

The automaker said it will recall more than 400,000 2010-12 Jeep Patriot and Compass SUVs -- including 254,000 in the United Sates -- to upgrade software that controls restraint-system function in certain types of accidents.

Chrysler Group is unaware of any injuries, accidents or complaints associated with the issue. Chrysler will notify owners next month. Chrysler is also recalling 45,400 vehicles in Canada and 109,400 around in other countries for the issue.

Separately, Chrysler is recalling about 220,000 2012-13 Jeep Wranglers to prevent premature wear to a transmission oil cooler line, including 181,000 of the SUVS in the United States.

A power-steering component may rub against the aluminum transmission oil cooler line and wear a hole in it. This can result in a loss of transmission fluid, which may cause damage to the transmission and loss of function. Chrysler said it is aware of 81 reports of problems, including two field reports.

The new recalls come after NHTSA last week asked Chrysler to recall 2.7 million Jeeps for fire concerns. NHTSA sent Chrysler a letter asking it to recall the 1993-2004 Jeep Grand Cherokee and 2002-07 Jeep Liberty.

NHTSA says fires caused by gasoline leaking from punctured gas tanks in rear-end crashes have killed 51 people. Depending on Chrysler's response, the safety agency will then decide whether to issue a formal finding and then convene a public hearing -- a final step before ordering a recall. Chrysler insists the vehicles are safe and meet all federal requirements.
