Mercedes Benz will be contacting the owners of certain 2019-2020 AMG G63 and G550 vehicles because they could contain a differential locking module control unit that does not meet the current production specifications.
According to the defect report, a resistor on the board could be affected by the sulfur fumes from the axle oil. If the resistor is impaired, the electrical current could increase and cause communications between the control unit and the locking actuator to be shut down. Both ESP and ABS system would be deactivated, increasing the risk of a crash under certain conditions. Drivers will be alerted of a problem through an illumined ABS and ESP message in the instrument panel.
Dealers will inspect the differential locking modules and replace them as necessary. The NHTSA Campaign Number for this recall is 20V-090.
Last month, an important case, for the first time put manufacturers on the hook for sales of used vehicles with problems beginning outside of the original manufacturer’s warranty, but still within the Certified Pre-Owned warranty. It has been unclear for years whether a manufacturer was required to buy back a used vehicle when the problems occurred after the original warranty expired. As long as the problems still occur during the CPO warranty, they’re subject to the lemon law. On the caveat, if the vehicle wasn’t purchased as a Certified Pre Owned vehicle, the manufacturer is off the hook if the problem occurs for the first time outside of the original warranty. The concern with this case, if any, would be that the Certified Pre-Owned program given by all manufacturers may be canceled since the manufacturers don’t want the added responsibility.
The case involves the sale of a certified preowned Mercedes Benz that still had a portion of the new vehicle warranty remaining and an additional used vehicle warranty from the manufacturer. An un-repairable defect manifested after the expiration of the new vehicle warranty, but during the duration of the used vehicle warranty. Mercedes Benz refused to repurchase the vehicle. The plaintiff sued and a jury found Mercedes Benz liable under the Song Beverly Act for breach of the express warranty and the implied warranty of merchantability. The plaintiff was awarded the same compensatory damages on both causes of action.
