Camaro SS steering woes. Any insight is appreciated
I have a 2017 SS that I've owned for 2 years now. Since last spring when I got it out for the first time, the steering has been very stiff. It's fine at super low speeds but anything over 20 mph it gets stiff. This is in tour mode. I had it to the dealer twice for diagnostics. They couldn't find any codes. The first time they fixed a loose connector but that didn't do anything. Does anyone have experience with this? And if so, how did you fix it? Thanks.

It isn't locked into Track Mode via the entertainment system settings, is it? In there you can manually set steering, exhaust (if you have NPP) and ride (if you have Mag Ride) so that it stays in that mode regardless of what mode the rest of the car is in...

No, I did check that and it has been locked in tour mode for steering setting.

Alas, I can't help solve the problem, but I do want to confirm that steering in tour mode should be MUCH lighter than track mode, the difference isn't subtle but very significant. Even if there are no codes, the service tech should troubleshoot further, this is not normal at all.
Out of curiosity, does your steering get even stiffer in track mode if you unlock it in settings (flipping it back to synced with the drive mode)? In other words, is there any response from the EPAS to setting changes but everything is super tight, or is it stuck in a very stiff setting and altogether ignores commands to change the steering feel?

Not sure on specifics but I'm sure other people will chime in on specifics.

It’s a long shot, but there was a recall for power steering problems on the 2017 Camaro. You can check for active recalls on your car at the Chevrolet website.

Sport is looser than track even at speed Touring is loose at all stages regardless of speed. it is also the loosest steering wheel out of all 3 modes. If power steering was out, at low speed or stand still it would be EXTREMELY hard to turn the wheel. Even more so if you have wide front tires.

The steering assist is electric, basically a small motor unit bolted onto the steering rack. Here is description from repair manual. If your unit is locking up at higher speed, but fine at low speed, I think the steering module may not be working right. As mentioned above, the low speed situation is where the unit works hardest mechanically. Good low speed action means it is probably not binding. Sounds like it may be "over stiffening" at higher speed.
The belt driven electronic power steering system consists of the following components: A belt drive and a ball nut mechanism A power pack; containing the power steering control module, its sensors, the power steering motor A torque sensor The steering gear (rack and pinion) The belt driven electric power steering system reduces the amount of effort needed to steer the vehicle by utilizing the power steering control module to control the power steering motor to maneuver the steering rack. The power steering control module uses input from the torque sensor, motor rotational sensor, battery voltage circuit and GMLAN serial data circuit to determine the level of motor assist. Vehicle speed and engine speed from the GMLAN serial data circuit is also used to adjust the amount of steering assist needed to steer the vehicle. At low speeds more assist is provided for easy turning during parking maneuvers. At higher speeds less assist is provided for improved road feel and directional stability The torque sensor is attached to the steering gear housing near the input shaft, and is critical to proper operation of the electronic power steering system. As the steering wheel is turned and torque is applied to the steering shaft, the torque sensor monitors the amount of input torque. The power steering control module responds to the torque sensor and motor rotational sensor by commanding current to the power steering motor. The power steering control module and motor are attached to the base of the steering gear housing, and applies power assist through the belt drive and ball nut mechanism to the steering rack. The ball nut mechanism translates the rotational movement of the belt drive system to lateral movement of the steering rack. The power steering control module has the ability to detect malfunctions within the electric power steering system. Any malfunction detected that disables steering assist will cause the SERVICE POWER STEERING message to be displayed on the driver information center. Additionally, the power steering control module calculates an internal system temperature which is used to protect the power steering system from damage caused by high temperature. When the calculated temperature exceeds a pre-determined level the amount of current commanded to the power steering motor is reduced. This will result in a temporary reduced level of assist. Full assist will return once the calculated temperature drops below the pre-determined level. |

I have not had the recall done because the steering has been fine. The failure mode will be increased turning effort at lower speed. No sign of that. I am happier to not have the dealer touch my car as long as it is working fine. I believe the problem in the "faulty" steering assist motors was related to an internal sensor which might fail. I have not had software updates done to the car. |
