{: ) Your stabilitrak system may not work properly. The vehicle need to be scanned for trouble codes. In case you get a C0196 code, the recommendation is to reprogram the electronic brake control module. I hope that's the only cause.

No it is not your transmission...it is your strutes and CV boot. This car has a lot of problems that need addressed...but your knocking noise one or the two... it'll be better to replace them booth at the same time.or both driver and passinger side will insure it..your machanic trying to burn you....hope this helps this was my problem with the knocking....

{: ) Turn off engine and open the hood.
Remove the front wheelhouse liner. The wheelhouse liner is sometimes called the mud guard or the splash shield, whatever. Whichever side, say we begin with the front left(drivers). If you dont wish to remove the front left tire, just turn the wheels far to the right to gain enough clearance. Start removing all those push pins and #7mm screws. And you dont need to remove the whole liner and all the screws and retainers. . Just remove only those nearest the headlight and front bumper area in order to loosen the front half portion of the wheelhouse liner. Just enough for your arms to move freely inside.
At this point, try your hands to reach in for the rear of the headlamp. Work your hands inside to remove ccw the bulb cap, and next on the low beam bulb. Note the position before turning it counterclockwise to remove. Release the bulb from the headlamp assembly (turn counterclockwise) Disconnect the electrical connector. Just remember the positioning of the bulb so you can swiftly reinstall a new bulb.

Note: If you still need more clearance for better movement, you can (1) remove the tire. or (2) remove the 3 screws that secure the bumper to the body, and then pull bumper outwards to loosen.Try to reach in again. If still not possible for you, proceed with the next step.

Remove the front sight shield that is covering the headlamps from above. This is the long plastic shield with seven pop up retainers . After removing the front sight shield, you will get a better view of the 3headlamp mounting bolts. The 4th one inside the wheelhouse liner.
Remove the 4 bolts of the headlamp assembly. Two on top, and one on both sides. Then pull the headlamp forward enough and try to reach in your hand to remove the bulb cover and then remove the bulb from its socket and connector. turn ccw to remove. Note also the bulb position before you remove it from its socket.
Still need more clearance? Remove the remaining pop-up retainers(6) thats supporting the front bumper fascia from above. It will be better if you have an assistant who can stretch out gently the loosened bumper on that particular side, while you carefully maneuver the headlamp assembly removal inch by inch. If in case still unlucky, or you if found later that the bulb connector is melted or burned, proceed furthermore and remove the headlamp assembly all the way.
A burned connector needs to be replaced and a new bulb installed, even if you find the old bulb not busted.
With all the parts removed, you wiill have a better view of all other components within that area, the park and signal bulbs, the horn, the fog lamp, so that the next time you need to work on them you'll have a better workplan. You may even bypass some steps mentioned earlier It's a matter of practice. I know its kinda tedious job for many owners. Just imagine removing so many screws for one simple bulb. But if you'll be patient enough, and get the hang of it, you will be saving labor costs and enjoy loving your Acadia.
I hope you remember how and where components were removed, so you wont be lost in the reinstallation. Okay ? goodluck. : )

What alarm ? content theft alarm ? No fuse When armed, the content theft deterrent (CTD) system is designed to deter vehicle content theft by pulsing the horns and exterior lamps for approximately 30 seconds when an unauthorized vehicle entry is detected. However, the CTD system does not affect engine starting. An unauthorized entry can be any of the following with the CTD system armed: • When any door is opened without first being unlocked using the keyless entry transmitter • After a battery reconnect, if the battery was disconnected with the CTD system armed The components of the CTD system are: • Body Control Module (BCM) • Security indicator • Door ajar switches • Liftgate ajar switch Is this the alarm your talking about ?

The radio and BCM needs read for codes. No reason for the radio not to work after a FOB program. Just a guess, but if the battery power was to low, radio is locked out.

The problem might be that the alternator is faulty or the idle screw is making the engine run at a very low speed when idle.

There is probably a small drain on the battery - perhaps the luggage compartment light isn't switching off. The car alternator isn't really capable of recharging a battery due to it's high internal impedance. It is better to recharge it independently.
