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.
0
Safety recallsA safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.

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.

Crash or fire reportedComplaints whose submitter recorded that a crash or a fire occurred. These are the reporter's own answers on the NHTSA form, not verified findings.

POWER TRAIN

Single throttle lift-off clunking noise from the side shaft when moving off (audible at the outboard end). The noise is heard once in each instance when changing direction of travel. Note: Sound file in attachment Cause If the complaint is eliminated by experimentally loosening the outboard collar nut (by 1 turn), the problem is due to cracking of the microweld between the wheel bearing inner race and the joint housing of the side shaft. Note: The collar nut must always be replaced after being loosened. See also LI33.20-P-078406 Remedy Coat contact surface of side shaft with wheel bearing with Molykote paint. To do this, proceed as follows: 1. Remove side shafts 2. Clean contact surface A (see image file in attachment "Outer joint housing before") before coating with Molykote, using "spirit" (free of dust and grease) 3. Coat contact surface A (see image file in attachment "Outer joint housing after") with Molykote and leave to dry for "one hour" in removed condition 4. Reinstall side shafts Note: Before using the antifriction coating (Molykote), stir it or shake it thoroughly for (at least 1 minute).

SERVICE BRAKES

Complaint The concern is characterized by BOTH of the following. 1. "Active Distance Assist currently unavailable" and "Active Brake Assist functions currently limited" are shown on the instrument cluster during startup or while driving AND 2. Stored DTC in quick test U0416FE - "Implausible data were received from control unit Traction system" in A108/1 (Distronic). Cause Missing wire between Drive Unit (N145) and Supercap (C8). Remedy Please reference the following attachments prior to starting work to familiarize and verify the locations of the components: • Drive Unit (N145) - See attachment "Location of Drive Unit in the vehicle". • Supercap (C8) - See attachment "Location of Supercap C8 in the vehicle". Professionally create a new connection by: • Using a red/white cable with cross-section 0.35 mm² and overall length of approximately 2m. • Connect Drive Unit (N145) plug A pin 18 to the 3-pin plug of the Supercap (C8) terminal 15 pin 2. Reference the new wire routing location as shown by the red line in "Picture 1 - Connection from Supercap to Drive Unit". • The new wire should be added to the existing wiring harness as shown by the red line "Picture 1 - Connection from Supercap to Drive Unit". • Z-Splice is the preferred method using A 000 982 91 10 for the Supercap (C8) connection. NOTE: All WIS instructions must be followed for wiring modifications. Damage code: 0 - 51422 - ** - 7 (for ** please state the following: "missing connection ex factory"). If the vehicle has had the modification completed and returns with an exact matching "complaint", please open a TIPS case.

LI68.20-P-080012

ELECTRICAL SYSTEM

Complaint USB port not functioning properly. Cause Most reported USB port issues are due to improper use or contamination. Note: Any repair costs must be discussed with the customer beforehand. Common external factors identified include: • Fluid intrusion • Broken bushings or physical damage See attachments. Remedy If a component needs replacement without visible external damage, submit a detailed TIPS case. Include information on all connected external devices (e.g., charging cables, USB drives, hard drives).

LI42.10-P-079904

SERVICE BRAKES

Complaint At low speeds and light brake pressure, brakes will make a groaning or honking noise. Cause Frictional vibrations with very light brake pressure/modulations. Remedy This condition can be duplicated on most vehicles. To validate, use a like for like reference vehicle. The noise is normal behavior under the conditions listed. With very light brake pressure this noise can be induced/caused due to normal brake pad and brake rotor vibrations. Exchanging brake components will not rectify.

Manufacturers file copies of the bulletins they send to dealers with NHTSA. These often describe diagnostic or repair procedures for a known condition. They are not recalls: repairs described in a bulletin are usually only free if the vehicle is still under warranty or the manufacturer has extended coverage.
