Recalls, owner-reported complaints, investigations and safety data
Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.
InvestigationsNHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.

STEERING
The steering wheel generates grinding noises between the steering wheel and steering column switch module during steering maneuvers See example file in the attachments area: Lenkrad-Schleifgeräusch_SteeringWheel-GrindingNoises.mp4 The plastic cover on the back of the steering wheel is not positioned correctly and may therefore rub against the steering column switch module Please use the following noise files for the damaged part analysis: 1. Grinding noise | pot. cause: steering wheel | see attachment: Lenkrad-Schleifgeräusch_SteeringWheel-GrindingNoises. mp4 2. Creaking/cracking noise | pot. cause: steering column switch module | see attachment: MRSM-Schleifgeräusch_ SCCM-GrindingNoises.MOV If the noise is due to the steering column switch module, please use LI46.10-P-077314. Check for grinding areas on the steering wheel: Please check the covers on the rear for protrusion and, if necessary, remount. 1. Mask off openings on back of steering wheel with adhesive tape 1. Mark the back of the steering wheel with colored chalk (see Picture 1) 2. Mount steering wheel on steering column switch module and turn the steering wheel from left lock to right lock ten times. 3. The chalk will now have disappeared in the areas where there is rubbing (see Picture 2) Warning: Ensure that no cables and visible areas of the steering wheel are damaged. The abrasive excess material on the back of the steering wheel must be carefully removed with a Dremel tool. Tip: You will need to remove approx. 0.1 mm to 0.3 mm of material (example: Picture 3) Make sure that none of the ground-off material gets into the steering wheel. After removing the material, clean the entire back of the steering wheel with a 1% soap solution.

STEERING
Noises in the steering column area when steering. Under analysis. Check which area of the steering column the noises occur in. Do the noises tend to occur at the bottom in the driver footwell or do they tend to occur in the area of the steering column switch module (MRSM/SCCM)? If the noises occur in the area of the MRSM/SCCM, work through the following points: - Loosen screws of the MRSM/SCCM and steering wheel, re-align the MRSM/SCCM, and re-fasten the screws (see WIS). Sometimes there is stress at the MRSM/SCCM and noises occur. - If noises continue to occur, swap the MRSM/SCCM into a vehicle without any (noise) complaints. - If the noises occur with the MRSM/SCCM complained about when it is in the vehicle without a complaint (donor vehicle), the MRSM/SCCM can be replaced. - If noises also occur in the customer vehicle with the MRSM/SCCM from the reference vehicle, the MRSM/SCCM is not the cause and must not be replaced. Notes: - When installing the MRSM/SCCM, make sure that no damage occurs! - Only disassemble and mount all component parts in the "straight-ahead position" (see also WIS). - Please refer to this LI in the "Notes" section of the warranty claim!
