My car's electric power steering assist began to stop working while driving to school ( it was working perfectly fine). I pulled over and restarted the car and the car alternated between working and not working. It eventually stopped working completely. Now I have a stability trak and steering assist reduce message on my dashboard. I am, unfortunately, out of warranty. I did some research on older models, as I was not able to find any information on the current gen Malibu. I decided to purchase a motor of from eBay and replace it with the one in my car before going to the dealer, as they charge just $140.00 to diagnose the car. Unfortunately, after replacing the motor, the problem remains. I've read that some people have had to have the motor/sensor reprogrammed in the previous gen of Malibu's. My question is, if I should return the motor I purchased ($90.00) and take the vehicle to the dealer? Or do you know if current gen Malibu's need to have the steering motor reprogrammed? I know the best thing to do is to take the vehicle to the dealer, but I'm someone who likes to learn about the mechanics of a vehicle.

Hi Cesar,

I attached the procedure for replacing the motor. However, it mentions that you need to transfer the key cycle information from the old control module to the new one. If you only replaced the motor then that is not needed.

However, I would not replace any other parts until you get the codes from the computer. That will point you in the correct direction. If you can get those from a parts store who will normally pull them for you, and provide those to me, I will happy to point you in the right direction.

I am sorry to hear this happened outside of warranty but this vehicle has electronically controlled power steering and this issue could just be a sensor, a module, or a wiring issue. Without those codes, we are just guessing.

Let me know and we can go from there. Thanks

Hey, thank you for taking the time to reply.
I took the vehicle to the dealership and was told the steering gear module is not communicating. The entire steering gear has to be replaced, and it's a 2400 dollar job if the dealership does it. I'm going to tackle the job myself for the most part, ill have someone transfer the cycle for me in town. I was wondering if you have any further information on how to replace the steering gear on a 2016 malibu ls. Also, do you know if the key cycle has to be captured before removing the steering gear from the vehicle?

Once again thank you for your time.

Hi Cesar,

Please find the procedure attached. I don't see where it requires you to do that prior to replacing.

However, the service procedure confirms what they are telling you. If you can't communicate then you must replace the entire assembly.

Also attached is the programming procedure however, it looks like you need a scan tool to do this. I would line this up before hand because I am not sure if you will be able to drive the vehicle after replacement. At least I am not sure if there will be any power steering.

Let me know if you have any questions. Thanks
