Proper Lifting of the ATS and CTS Sedan When lifting the 2013-2014 ATS and 2014 CTS Sedan on a hoist, the vehicle should be lifted so that the hoist pads and/or lift arms do not contact the rocker panel molding. Each hoist pad must be located in the designated area in order to prevent any damage to the vehicle. (Fig. 12) Fig 12 In the front location, place the lift pads on the rocker outer panel weld flange. (Fig. 13) Fig 13 In the rear location, place the lift pads on the rocker outer panel rear cradle brace. (Fig. 14) Ensure the hoist pad is inside the rocker panel molding cut out area (notch). Fig 14 Damage may occur to the rocker panel molding where it contacts the lower front of the quarter panel (dog leg) if the rear hoist pad contacts the rocker panel molding and shifts the position of the molding, which may result in the paint peeling where it meets the step in the body panel.

Void in Carpet The 2013 ATS built prior to December 21, 2012 may have an oval cutout or void in the carpet on the passenger’s side of the center console. (Fig. 7) Fig 7 The carpet is cut correctly and does not need to be replaced. Instead, the carpet fit must be finessed. Remove the console to allow the carpet to rise to the proper position and then reinstall the console. If the carpet does not come up enough for the cutout to be covered, the seat may need to be removed to allow the carpet some slack. (Refer to #PIC5807 before removing the seat bolts.) If the cutout in the carpet (Fig. 8, 9, A) does not stay up under the console, foam may need to be added under the carpet on the floor (Fig. 8, 9, B)near the console. Fig 8 Fig 9 Without the foam, the carpet is allowed to be pushed down and pulls the cutout with it.
Loss of Rear Trim Height On the 2013 XTS, it may be noticed that the vehicle is sitting lower after being parked for several days or more. Normal diagnostics for Air Suspension Air Leaks or Low/Uneven Trim Height may be completed with no trouble found Under normal conditions, it is typical for the air suspension system to drop up to 0.5mm of trim height per 24-hour period . Changes in temperature also can affect trim height: The trim height can be expected to drop as much as 2.6mm for every 10°F (5.6°C) drop in ambient temperature . It should be considered normal operation if a vehicle loses trim height when parked and unused for several days, but achieves and maintains normal trim height when cycling the ignition and using the vehicle regularly . No repairs should be attempted . Remind customers that cycling the ignition or starting the vehicle will bring the trim height back to a normal level
Fluid in Spark Plug Tubes March 25, 2013 A Check Engine light may be illuminated with misfire DTCs set, or a possible oil or coolant leak may be found, on some 2010-2013 Enclave, LaCrosse, CTS, SRX, Camaro, Equinox, Traverse, Acadia, Terrain; 2012-2013 Caprice PPV, Captiva, Impala; 2013 ATS and XTS models equipped with 3.0L and 3.6L (RPOs LF1, LFW, LLT, LFX) HFV6 engines. (Fig. 10) Fig 10 On inspection, coolant or oil may be found in a spark plug tube. Determine if the oil or coolant is coming from the spark plug tube and not leaking into it from above. If the spark plug tube is leaking, replace the cylinder head, spark plug and coil. Porous spots in the head created during manufacturing cause the leak. The spark plug tubes are permanently sealed into the head and are not replaceable. If a cylinder head is replaced for this condition, mark the faulty spark plug tube before sending the head in for warranty or core so GM Engineering or the re-manufacturing facility can identify it.
