Service bulletin 122-K5X7U-05
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

| 122-L7P4X-03 | 2018-03-13. Service bulletin. The "transfer case" is designed as an active all-wheel drive system that is dynamically adapted to the respective driving state. Power transmission between the front and rear axle is controlled electronically via the "all-wheel drive servomotor (transfer case)" and themulti-plate clutches integrated in the transfer case. ? On all-wheel drive vehicles, the drive train can become strained at low speeds and when the steering is turned sharply when "Off-roadmode" is activated, depending on design. ? Under extreme conditions, the drive train can also become strained when "Off-roadmode" is deactivated. ? Customers with little experience with all-wheel drive vehicles can interpret this behavior as a fault, which in turn can result in incorrect diagnoses in the workshop. Remedial action: Customer complaint to be checked: ? Rough-running engine or ? thevehicle vibrates or ? theengine jerks under load/during acceleration. |

| 122-E8R2D-05 | 2017-09-14. Service bulletin. Concerns: All-wheel drive control unit Information: This is to inform you of a voluntary Workshop Campaign on the above-mentioned vehicles. Due to an error in the current software for the all-wheel drive control unit, there is a possibility that the all-wheel drive control unit will not be initialized at times after switching on the ignition and as a result, the vehicle's CAN system cannot establish communication with the all-wheel drive control unit. |
