2017-2020 Maserati Levante Steering Column: Decoding Part Numbers and Common Failures
This guide clarifies common part number confusion and details symptoms, inspection points, and replacement costs for the 2017-2020 Maserati Levante steering column assembly.
- A common point of confusion is part number 670043350, which is a trim piece; the correct assembly is typically 670033944.
- The most critical failure symptom is a physically loose or wobbling steering column, which makes the vehicle unsafe to drive.
- Failure of the power tilt/telescoping motor is a known issue, often requiring replacement of the entire column assembly.
- There are no specific recalls for the steering column housing, but replacement is a complex job requiring airbag removal.
Symptoms of a Failing Steering Column Housing
Failures in the Levante's steering column assembly can manifest as physical looseness, unusual noises, or problems with its electronic features. Identifying the specific symptom is key to a correct diagnosis.
Loose or Wobbly Steering Wheel
The most serious symptom is any noticeable play, wobble, or looseness in the steering wheel that is not related to turning the wheels. This often points to cracked mounting points on the housing or worn internal bearings. This looseness can feel like a slight vibration at first but can progress to significant, unsafe movement in the entire column assembly. Driving with a loose steering column is extremely dangerous.
Noises When Turning or Adjusting
Audible cues often signal a problem. Listen for grinding, clicking, or squeaking noises that occur when turning the steering wheel or adjusting its position. These sounds can be caused by worn bearings, a failing tilt/telescope motor, or debris inside the column assembly. A metallic clicking sound at full lock while moving slowly can also be related to suspension geometry and may not be the column itself.
Failure of Power Tilt/Telescope Function
For models equipped with power adjustment, a common failure is the inability to move the steering wheel up, down, in, or out. The motor may make no noise, or you might hear it struggle. On some Levantes, the column has been known to get stuck in one position, particularly the telescoping in-and-out function. Sometimes the tilt-away feature (which moves the wheel up and away upon exit) will stop working.
Known Issues, Recalls, and Part Number Clarification
While the 2017-2020 Maserati Levante has been subject to several recalls, none directly address the steering column housing or assembly. Recalls for this period include issues with engine software that could cause stalling, seat wiring harnesses, and backup camera malfunctions.
Part Number Warning: The OEM part number 670043350 is often misidentified as the steering column housing. Research shows this part number corresponds to the left lower dash trim cover / knee bezel, which is a plastic trim piece located below the steering column. The correct part number for the complete steering column assembly with electrical adjustment appears to be 670033944. Always verify the part number on your original unit before ordering a replacement.
Buying a Used 2017-2020 Levante Steering Column Housing
Due to the high cost of a new OEM assembly, a used part is often the most economical solution. The steering column is primarily a structural and electro-mechanical part, making a quality used OEM unit a reliable choice. Here’s what to inspect before buying.
Physical Inspection
- Check for Cracks: Carefully inspect all plastic and metal mounting points. Pay close attention to the areas where the assembly bolts to the dashboard support and where components like the ignition switch and combination switch attach. Stress fractures are a major red flag.
- Examine the Wiring: Look for any cut wires, damaged connectors, or signs of previous repair (like electrical tape). The wiring harnesses should be intact and complete.
- Test the Adjustment Mechanism: If possible, apply 12V power to the tilt and telescope motor pins to verify they function in both directions. If you cannot test it, ask the seller to guarantee its function.
- Look for Accident Damage: Avoid any column that shows signs of being bent, deformed, or heavily impacted. A steering column is designed to collapse in a frontal collision, and a part from a wrecked vehicle may be compromised.
Compatibility
The most critical step is to match the part number exactly. Ensure the replacement part is 670033944 or the specific number from your original column. The Levante was equipped with different column options, and using the wrong one can result in non-functioning power adjustments or other electrical issues. A used OEM part ensures perfect fitment for all the switches, trim, and mounting hardware.
Cost Comparison
Replacing the steering column assembly is a significant expense, with the part itself being the largest cost. A used OEM part offers substantial savings.
| Part Type | Estimated Cost |
|---|---|
| New OEM Assembly (Part #670033944) | $1,400 - $1,600 |
| Used OEM Assembly | $450 - $650 |
| New Aftermarket | Not Generally Available |
| Shop Labor | $400 - $700 |
Replacement Information
Replacing the steering column assembly is a complex job that involves critical safety components like the airbag and steering wheel.
- Difficulty: 4 out of 5
- Estimated Time: 3-5 hours
- DIY Feasible: Not recommended for beginners. This job is best for experienced DIY mechanics or professionals due to the need to safely handle the airbag module and steering wheel removal.
Warning: You must disconnect the vehicle's battery for at least 30 minutes before beginning any work to allow the airbag system's backup power to discharge. Failure to do so can result in accidental airbag deployment, which can cause serious injury.
A general overview of the replacement process includes disconnecting the battery, removing the driver's airbag, removing the steering wheel, removing the upper and lower column shrouds and knee bolster, disconnecting all electrical connectors to the column, removing the clock spring and combination switch, and finally, unbolting the entire column assembly from its mounting bracket on the dash support.
Frequently Asked Questions (FAQ)
Is a clicking noise when I turn always a bad steering column?
Not always. Clicking or popping noises can also come from worn CV joints, ball joints, or tie rod ends. If the noise only happens when the vehicle is moving, it's more likely a suspension or axle component. If the noise occurs when turning the wheel while stationary, the steering column bearings or intermediate shaft are more likely culprits.
Do I need to reprogram the car after replacing the steering column assembly?
Typically, the housing and motors themselves do not require programming. However, the steering column assembly contains the clock spring and steering angle sensor. If you are transferring your old clock spring/sensor to the new column, no programming should be needed. If the replacement column comes with these sensors, a steering angle sensor calibration may be required using a diagnostic scan tool to ensure the stability control system functions correctly.
Can I just replace the tilt/telescope motor?
The individual motors are not typically sold separately by Maserati. They are considered an integrated part of the steering column assembly. Replacing the entire used assembly is often the most practical and cost-effective repair method.
Why is my steering wheel stuck? It won't move up or down.
This is a common symptom of a failed adjustment motor or a jam in the gear mechanism within the column. It can also be caused by a faulty switch or a blown fuse. Check the fuse for the power steering column first. If the fuse is good, the problem is likely the motor or control module within the column assembly itself.
