2017-2020 Chevrolet Sonic Steering Column: Decoding Keyless, Wiper, and Body Style Options

Symptoms of a Failing Steering Column

Problems with the Sonic's steering column can manifest as either mechanical or electrical issues. Because it integrates so many different functions, a single point of failure can create a variety of symptoms.

1. Intermittent Loss of Power Steering

One of the most concerning symptoms is a sudden loss of electric power steering (EPS), often accompanied by a warning light on the dash. You may start the car and find the steering is extremely heavy and difficult to turn. This can be intermittent, sometimes resolving itself after the car is turned off and sits for a few minutes. Forum discussions have pointed to an internal failure in the column's control module, which may store a fault code like C0475. While the car can still be steered manually, it requires significantly increased effort, especially at low speeds, posing a safety risk.

2. Noises When Turning

Clicking, popping, or grinding sounds coming from directly behind the steering wheel often point to problems within the column. This could be a worn-out bearing, a failing turn signal cancel cam, or a problem with the clockspring (the coiled wire that allows the steering wheel to turn while maintaining electrical connections for the airbag and horn).

3. Malfunctioning Switches

Since the turn signal and wiper/washer switches are integrated into the steering column assembly, their failure is a common symptom. You might experience turn signals that don't activate or don't cancel after a turn, or wipers that won't turn on, switch speeds, or stop in the correct position. In many cases, the entire multi-function switch assembly, which is attached to the column, needs to be replaced.

4. Loose Steering Wheel

A feeling of excessive play or looseness in the steering wheel can be caused by worn internal bearings or a problem with the tilt/telescoping mechanism. If the wheel can be wiggled up-and-down or side-to-side without affecting the wheels, the column itself should be inspected.

Known Issues, TSBs, and Recalls

As of mid-2026, there are no active recalls specifically for the steering column assembly on 2017-2020 Chevrolet Sonic models in the North American market. However, a few related Technical Service Bulletins (TSBs) for earlier models are worth noting for diagnosis:

• TSB 16-NA-118: This bulletin notes that chafing of the engine wiring harness on an ECM stud could cause a loss of steering assist, among other issues. This highlights the importance of checking wiring before replacing expensive components.
• TSB PI1350A: For older Sonics (2012-2014), this bulletin stressed the importance of matching the steering gear with the correct Electronic Power Steering (EPS) calibration. While not directly for the 2017-2020 models, it shows that GM's EPS systems are sensitive to software and hardware matching.

Buying a Used 2017-2020 Sonic Steering Column

A used OEM steering column is an excellent, cost-effective alternative to an expensive new part, but careful verification is absolutely essential. Due to multiple variations, you cannot simply buy any column from a 2017-2020 Sonic. You must match the part to your vehicle's specific options.

How to Verify Compatibility

Before purchasing, you must know your vehicle's configuration. The best way to do this is by checking the Service Parts Identification (SPID) label, which lists your car's three-character Regular Production Option (RPO) codes. On the 2017-2020 Sonic, this label is typically found inside the glove box or as a QR code on the driver's side door jamb.

You need to confirm three key things:

1. Body Style: Is your Sonic a Sedan or a Hatchback? The columns are different because hatchback models have a rear wiper switch.
2. Ignition Type: Does your car have a traditional metal key or Keyless Ignition (Push-Button Start)? The RPO code for keyless start is BTM. A column for a keyed car will not work in a keyless car, and vice-versa.
3. Rear Wiper Options (Hatchback Only): If you have a hatchback, does it have the optional Delay Rear Wiper? The RPO code for this is CD4. There are different columns for hatchbacks with and without this feature.

Physical Inspection Checklist

• Connectors: Carefully inspect all electrical connectors. Look for bent pins, cracked plastic housings, or cut wires. A damaged connector can be very difficult to repair.
• Switches: Check the turn signal and wiper stalks. Are they physically intact? Do they move through their functions with a solid feel?
• Shaft and Housing: Look for any signs of impact damage, bends, or corrosion on the column's main housing. A column from a collision-damaged vehicle may have compromised its collapsible safety design.
• Wiring Harness: Ensure the entire wiring harness attached to the column is complete and has not been cut or damaged during removal from the donor vehicle.

Cost of Replacement

Replacing a steering column is a labor-intensive job. Prices for parts can vary dramatically between new OEM, aftermarket, and used OEM options.

Replacement Overview & Difficulty

• Difficulty: 4 out of 5 (Advanced)
• Estimated Time: 2.5 - 4 hours
• DIY Feasible?: Not recommended for beginners. This job requires handling the airbag system, which is dangerous if done incorrectly. It also requires specific tools like a steering wheel puller.

The general replacement process involves disconnecting the battery, waiting several minutes for the airbag system to discharge, removing the driver's airbag and steering wheel, removing the plastic shrouds around the column, disconnecting numerous electrical connectors, unbolting the intermediate shaft, and finally unbolting the column assembly from the dashboard support structure.
