Check Transmission Wiring Harness Connector – 2019-2023 Mercedes-Benz CLS-Class, E-Class, & GT-Class

SEOCONTENT-START

Chronology of Defect/Noncompliance Determination Supplement for ODI 22-00855-28172-10
In August 2019, MBAG was made aware of several cases in the U.S. in which customers received warnings via the vehicle instrument cluster regarding the 12V battery (electrical charge indicator) and/or the 4Matic system (“4Matic malfunction”). MBAG investigated these cases and determined that corrosion of a transmission wiring harness electrical connector on triggered the messages in the instrument cluster. MBAG returned affected parts to Germany for inspection and testing regarding potential effects of corrosion in the electrical connector. At that time, MBAG’s investigation identified no risk of fire or other safety risks.
In August 2021, MBAG was made aware of field cases involving thermal events that occurred outside of the U.S. MBAG launched extensive investigations into potential causes of these field cases. As part of its investigation over the course of several months, MBAG evaluated the effects of different types of short circuits on the transmission wiring harness electrical connector. MBAG also compared the electrical resistance of corroded and non-corroded electrical connectors using computed tomography.
In the beginning of 2022, MBAG determined that production deviations in the routing and the length of the cable in the transmission wiring harness caused mechanical strain on the single-wire seal. Separation of the seal could allow water to penetrate the electrical connector. In April 2022, MBAG implemented a production change by using a longer harness and optimizing the harness position. MBAG also developed an additional bracket to optimize the routing of the transmission wiring harness on potentially affected vehicles in the field.
MBAG continued further investigation to assess whether corrosion in the electrical connection could pose a fire or other safety risk. Based on its investigation, MBAG identified forty-nine warranty claims in connection with this issue in the U.S. from February 13, 2019 to March 31, 2022. MBAG determined that two such claims alleged thermal events involving the affected vehicle. On July 15, 2022, MBAG determined that a potential safety risk cannot be ruled out and decided to conduct a recall.

Our records indicate that your vehicle is included in the affected population.
What is the concern?
The transmission wiring harness may be misrouted, which could expose the electrical connector to corrosion, and result in an electrical short-circuit. An electrical short-circuit can increase the risk of a fire. Before the issue occurs, the driver may be alerted to the condition by illumination of the yellow battery (electrical charge) indicator lamp and/or the “4Matic malfunction” warning message in the instrument cluster. Unfortunately, the parts to remedy this are not yet available. We are working to obtain the necessary parts to correct this condition as quickly as possible. As parts become available, we will send you another letter asking you to take your vehicle to an authorized Mercedes-Benz dealer to have the recall completed free of charge. An authorized Mercedes-Benz dealership will inspect and repair the electrical connector, as necessary. The wiring harness will also be re-routed and receive an additional bracket. Should you have any concerns or questions regarding your vehicle before you receive the next recall letter when parts are available, please contact an authorized Mercedes-Benz dealer. If for any reason a dealer is unable to remedy your situation, we are always happy to hear from you. Please contact us at 1-800-367-6372. A vehicle identification number (VIN)-based recall lookup tool on our MBUSA.com website offers a search function that will indicate whether a vehicle has been subject to a safety recall, and whether that vehicle has had the free remedy performed.

August 25, 2022
Check Transmission Wiring Harness Connector This is to notify you of an update for the Recall Campaign to check the transmission wiring harness connector on 16,475 Model Year (“MY”) 2019-2022 4-Matic CLS-Class, E-Class, and GT-Class (257, 213, 238, and 290 platform ) vehicles. The recall campaign will be visible on the www.safercar.gov website and may generate questions from customers. Affected VINs were flagged in VMI as “PENDING” on July 29, 2022.
Background
Mercedes-Benz AG (MBAG), the manufacturer of Mercedes-Benz vehicles, has determined that on certain E-Class (213 platform), E-Class Coupe/Cabriolet (238 platform), CLS (257 platform) and AMG GT 4-door (290 platform) 4Matic vehicles, the transmission wiring harness might not be routed according to specifications. Tension on the transmission wiring harness could lead to wire Issue What We’re Doing Parts insulation pulling back from the electrical connector and as a result, water could enter the connector. Water ingress may lead to a short circuit and/or thermal overload if the vehicle’s ignition is off for longer periods of time. The risk of fire cannot be ruled out. Before the issue occurs, the driver may be alerted to the condition by illumination of the yellow battery (electrical charge) indicator lamp and/or the “4Matic malfunction” warning message in the instrument cluster.
MBUSA will conduct a voluntary recall. An authorized Mercedes-Benz dealer will check the electrical connector on the affected vehicles and rework it, if necessary.
Remedy is not available at this time.

Loaner and demonstrator vehicles may continue to be driven, but must not be retailed until repaired. As a matter of normal service process, please check for other repair measures that might be applicable to the vehicle(s). Additionally, given this notice, it is a violation of Federal Law for car rental companies to rent new MY19-22 CLS-Class, E-Class, and GT-Class covered by this notification until the vehicle has been repaired.

FMVSS 1 : NR FMVSS 2 : NR
Description of the Safety Risk : Tension on the transmission wiring harness could lead to wire insulation
pulling back from the electrical connector. As a result, water from external sources could penetrate the connector. The presence of water may create a short circuit over time. As a result, the short circuit could lead to thermal overload if the vehicle’s ignition is off for longer periods of time.
Subsequently, the risk of fire cannot be ruled out.
Description of the Cause : Due to a routing deviation in the transmission wiring harness specifications during vehicle production, a tension on the harness might cause the wire insulation to be pulled back and as a result not fulfill sealing requirements into the electrical connector.

Description of the Safety Risk : Tension on the transmission wiring harness could lead to wire insulation
pulling back from the electrical connector. As a result, water from external sources could penetrate the connector. The presence of water may create a short circuit over time. As a result, the short circuit could lead to thermal overload if the vehicle’s ignition is off for longer periods of time.
Subsequently, the risk of fire cannot be ruled out.
Description of the Cause : Due to a routing deviation in the transmission wiring harness specifications during vehicle production, a tension on the harness might cause the wire insulation to be pulled back and as a result not fulfill sealing requirements into the electrical connector. Identification of Any Warning
that can Occur : Before a short circuit occurs, the driver could be alerted to the condition by illumination of the yellow battery (electrical charge) indicator lamp and/or the “4Matic malfunction” warning message in the instrument cluster.
