Problems like this are hard to diagnose because they are intermittent. You need a good auto electrician with a $5,000 scan tool computer. They check all the modules, sensors and the ECM and run two way data. The can also take the vehicle for a run and record what happens when it cuts out. The most likely suspect is the Body Control Module and the model has a history of issues.

Fuel pump or filter? Without testing your guess is as good as ours , Do yourself a favor an have it towed to a qualified repair shop. Besides , could be other thing's as well .
Are you sure it is the sway bar you are looking at? Sway bars are bent to start with to do their jobs so the left end will be a mirror to the right end. So by 'bent' I'm assuming you mean one side isn't a mirror to the other.
Most sway bars are mounted with 6 bolts. 1 bolt at each end at each hub and two on each U clamp holding the sway bar bushes in place. Sway bars need to flex and bend to do their job so they shouldn't be welded in place.
Could you comment below with photos of the part your looking at and where it is on the vehicle?
On some vehicles you'll need to lower the front sub frame to get the actual sway bar out so it's often a job you can't really do on you drive.
Comment below with more information and I'll try to help you more.
The switch need to be replaced. This is a common problem. Understand that he switch is the only breakpoint in that system. If the seat is getting hot without the switch being pressed, there is a short in the switch, thuis the necessary replacement.
The odometer will display 'error' if an internal IPC memory failure is detected or if there is a serial data communication fault between the ECM and the BCM. IPC instrument panel cluster .
Circuit Description
The communication among control modules is performed through the GMLAN high speed serial data circuit and the GMLAN low speed serial data circuit. The modules that need real time communication are attached to the high speed GMLAN network. The body control module (BCM) is the gateway between the networks. The purpose of the gateway is to translate serial data messages between the GMLAN high speed buss and the GMLAN low speed buss. The gateway will interact with each network according to that network's transmission protocol. Refer to Body Control System Description and Operation for more information about the gateway.
Your best bet is to take your vehicle to the dealer , sorry !
I"m not a fixya Expert. But few days ago I faced this problem and got some good sources of this problem. Hope it

That vehicle has 3 relays ,not just 2 . Two cooling fans .
Cooling Fan Control
The engine cooling fan system consists of two electrical cooling fans and three fan relays. The relays are arranged in a series/parallel configuration that allows the powertrain control module (PCM) to operate both fans together at low or high speeds. The cooling fans and fan relays receive battery positive voltage from the underhood junction block. The ground path is provided at G103.
During low speed operation, the PCM supplies the ground path for the low speed fan relay through the low speed cooling fan relay control circuit. This energizes the cooling fan 1 relay coil, closes the relay contacts, and supplies battery positive voltage from the cool fan 1 fuse through the cooling fan motor supply voltage circuit to the left cooling fan. The ground path for the left cooling fan is through the cooling fan s/p relay and the right cooling fan. The result is a series circuit with both fans running at low speed.
During high speed operation the PCM supplies the ground path for the cooling fan 1 relay through the low speed cooling fan relay control circuit. After a 3-second delay, the PCM supplies a ground path for the cooling fan 2 relay and the cooling fan s/p relay through the high speed cooling fan relay control circuit. This energizes the cooling fan s/p relay coil, closes the relay contacts, and provides a ground path for the left cooling fan. At the same time the cooling fan 2 relay coil is energized closing the relay contacts and provides battery positive voltage from the cool fan 2 fuse on the cooling fan motor supply voltage circuit to the right cooling fan. During high speed fan operation, both engine cooling fans have there own ground path. The result is a parallel circuit with both fans running at high speed.
The PCM commands Low Speed Fans on under the following conditions:
• Engine coolant temperature exceeds approximately 106°C (223°F).
• A/C refrigerant pressure exceeds 1310 kpa (190 psi).
• After the vehicle is shut off if the engine coolant temperature at key-off is greater than 140°C (284°F) and system voltage is more than 12 volts. The fans will stay on for approximately 3 minutes.
The PCM commands High Speed Fans on under the following conditions:
• Engine coolant temperature reaches 110°C (230°F).
• A/C refrigerant pressure exceeds 1655 kpa (240 psi).
• When certain DTCs set.

When your water pump goes bad it will begin to grind. I had one I let got far to long and it sounded deafening when I opened the hood. You can open your hood and listen and see for yourself. The water pump is on the belt line, left side under the hood, last pulley toward the rear.
Now if your asking can an oil change effect the water pump? No, not at all. Water pumps go sporadically.
It would be odd that you heard no noises before the oil change and now the water pump is loud enough to take notice after the oil change. The bearings usually go a little slower than that.
I would be interested in some more of the details to this. And what your overall concerns are. I'd be happy to further. help. Otherwise get a second opinion on your cars condition.
Since the manifold is an important component of the engine's exhaust system and helps ensure that the engine receives the proper amount of backpressure (the pressure developed by the exhaust system as gasses are evacuated), a cracked manifold can negatively impair engine performance. A crack is, in essence, a vacuum leak and may prevent all of the engine functions from operating correctly..
