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.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2018/MC-10130120-9999.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2018/MC-10130120-0001.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10130120","components":[{"id":"powertrain","name":"Transmission and driveline","parent":null},{"id":"transfer-case","name":"Transfer case","parent":"powertrain"}],"codes":[],"topics":[],"vehicles":[{"make":"PORSCHE","model":"MACAN","year_from":2015,"year_to":2018,"match":"exact","vehicle_ids":["2015_porsche_macan","2016_porsche_macan","2017_porsche_macan","2018_porsche_macan"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
