Still in the hot seat after its massive ignition recall, GM has announced another round of recalls unrelated to that issue. The first involves a faulty transmission control module in more than 50,000 2013 model-year Cadillac SRX crossovers. The other involves a fuel pipe that could leak on some 2015 model-year GM heavy-duty pickups with the diesel engine and dual fuel tanks.

2013 Cadillac SRX

The Problem: The transmission control module (TCM) on some SRX models equipped with the 3.6-liter V-6 engine is defective, causing a three- to four-second delay in acceleration in certain driving situations.

The Fix: GM will notify owners, and dealers will reprogram TCM units free of charge. The automaker has not yet provided a notification schedule, but owners can contact Cadillac at 1-800-458-8006 using the recall number 14132 for more details.

Number of Vehicles Potentially Affected: The recall affects 50,571 model-year 2013 Cadillac SRX models with the 3.6-liter V-6, and manufactured between May 29, 2012 and June 26, 2013.

2015 Chevrolet Silverado HD

The Problem: Certain Chevy Silverado and GMC Sierra HD trucks with the 6.6-liter Duramax turbodiesel V-8 engine and dual fuel tanks have a fuel pipe connecting the tanks to the fuel transfer pump that may not be properly torqued, which could result in a leak, and subsequently a fire.

The Fix: GM will notify owners beginning May 19, and dealers will tighten the fuel pipe connections to the proper specs. Owners can contact Chevrolet at 1-800-222-1020 or GMC at 1-800-462-8782 using the recall number 14067.

Number of Vehicles Potentially Affected: The recall affects just 51 2015 model-year Chevrolet Silverado HD and GMC Sierra HD pickups manufactured between February 11, 2014 and February 19, 2014, and equipped with the diesel engine and dual tanks.
