General Motors (GM) is once again facing recall issues.

In the United States, the automaker is recalling the 2013 Cadillac SRX luxury crossover and the 2015 Chevrolet Silverado HD and 2015 GMC Sierra HD heavy-duty pick-up trucks.

About 50,571 units of the SRX, equipped with 3.6-liter V6 engines and manufactured from May 29, 2012 to June 26, 2013, are being recalled because of possible delays in acceleration due to the transmission control module (TCM) programming.

The National Highway Traffic Safety Administration (NHTSA) said in a press release that the three-to-four-second lag in acceleration may increase the risk of a crash.

With this, GM is expected to notify the owners and to reprogram the TCM. But according to the NHTSA, GM has not yet provided a notification schedule.

On the other hand, about 51 units of the newly released Chevrolet Silverado HD and GMC Sierra HD, equipped with diesel engines and dual fuel tanks, and manufactured from Feb. 11 to 19, 2014, will also be recalled.

The NHTSA said “the fuel pipe connections on both sides of the diesel fuel transfer pump may not be properly torqued which may result in a diesel fuel leak,” which could cause a vehicle fire.

GM’s recall for the Silverado and the Sierra is expected to begin on May 19, 2014, the NHTSA said.
