There may be a lack of power
steering assist on some
2013Regalsequippedwith
electric power steering (RPO
NJ1).Thisconditionmaybe
caused by a poor connection
at G111.
On vehicles built prior to
August 26, 2011, the nut on
the ground post may have
been loose, which may have
allowed paint to enter under
the nut and negatively impact
the ground connection.
Remove the nut and wire
from ground post G111
and inspect the base of the
ground post and the base
of the ground nut. If paint
is found, clean the ground post base and replace the M6 nut (GM P/N
11609767).Torquethenutto8Nm(71lb.in.).

Wobble Felt during Acceleration
through 1-2 Shift
On some 2011-2012 Regals, a wobble sensation may be felt in the vehicle or steering
when accelerating from a stop through the 1-2 shift and/or there may be a slip/stick
condition when the vehicle shifts from 1-2 up to approximately 20 mph. The condition
may be easier to duplicate with a passenger in front and/or turning to the right while
accelerating.
A new design half shaft is now available to address this condition. Order both the left
and right half shafts.
TIP: Once these half shafts have been installed, perform the following break-in
procedure:
1. From a stop, accelerate at wide-open-throttle through the 1-2 shift up to 40 mph.
2. Decelerate to a stop.
3. Repeat steps 1 & 2 a total of 20 times.

Inspect the base of the ground post and the
base of the ground nut for paint.
