371430200365862022-11-21. Service bulletin. POWER TRAIN. Vehicle lacks power or will not move after stop due to simultaneous depressing of the brake and accelerator pedals
371424203712712022-11-21. Service bulletin. POWER TRAIN. Jerky accelerator response in reverse gear
3714222028985112022-11-21. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM); LANE DEPARTURE; ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL. Transmission warning message in cluster (P074100 stored in TCM)
371448203000752022-11-21. Service bulletin. POWER TRAIN:MANUAL TRANSMISSION:COLUMN SHIFT ASSEMBLY. Customer may report harsh shift concerns; no faults are stored and concern is reproducible
1421203900622022-08-01. Service bulletin. POWER TRAIN; STEERING. The circlip connecting the turbo wastegate actuator rod and the wastegate flap lever can fall of due to low tension of the clip. Consequently, the wastegate linkage becomes disconnected, causing MIL on and DTC P029900.
1420203900612022-08-01. Service bulletin. POWER TRAIN; STEERING. The circlip connecting the turbo wastegate actuator rod and the wastegate flap lever can fall of due to low tension of the clip. Consequently, the wastegate linkage becomes disconnected, causing MIL on and DTC P029900.
1338201291352022-08-01. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:FLUID/LUBRICANT:FILTER/SCREEN. Engine oil service - filter cartridge replacement. When changing the oil filter and installing the new filter seal(s) in the oil filter housing, special attention is required.
37 13 07 20336582022-05-31. Service bulletin. POWER TRAIN. Vehicle lacks power or will not move after stop due to simultaneous depressing of the brake and accelerator pedals
30 13 18 20282292022-05-31. Service bulletin. ELECTRICAL SYSTEM; POWER TRAIN:MANUAL TRANSMISSION; ENGINE. Vehicle does not start or only starts when the clutch pedal is pressed very firmly
37 14 30 20036582022-05-02. Service bulletin. ELECTRONIC STABILITY CONTROL (ESC):CONTROL MODULE:SOFTWARE; POWER TRAIN. This condition may be caused when the brake pedal and the accelerator pedal are depressed simultaneously. Drivers who drive with their left foot resting on the brake pedal are prone to experience this condition. With the introduction of Electronic Power Control (EPC) (no accelerator cable) to fuel injection systems, an engine RPM control feature has been incorporated into the engine electronic control system software. Customer states that the engine returns to idle speed of approximately 1,400 RPM although the accelerator is depressed, and/or the vehicle hesitates (lacks power on take-off).
37 14 24 20371272022-05-02. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM); ELECTRICAL SYSTEM:SOFTWARE; POWER TRAIN; ELECTRICAL SYSTEM. A jerky accelerator response is felt when the vehicle is pulled away from a stop in reverse. Incorrect calibration of clutch program. New software in the transmission control module (TCM), J217 (address word 02) addressed the condition.
37 14 22 20289852022-05-02. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE; UNKNOWN OR OTHER; POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM). The fault occurs with ATF temperature below 60° C. Check for this temperature range in the extended environmental conditions of the diagnosis protocol. This TSB only applies if the ATF level is correct and there are no leaks.
37 13 09 20287152022-05-02. Service bulletin. ELECTRICAL SYSTEM:12V/24V/48V BATTERY; POWER TRAIN:AUTOMATIC TRANSMISSION:INTERNAL:GEARS. After a mechatronics, torque converter, or complete gearbox replacement, the clutches must be adapted to the new component. This requires a gradual move of the clutch linings toward the optimal operating points in the most diverse load conditions. As a result, sporadic driving power disruptions lasting for less than a second or reduced shift comfort are possible over the first 500 miles. This is normal, and these issues will decrease over time. The issues can also occur if the adaptation values of the gearbox were deleted.
30 13 18 20282292022-05-02. Service bulletin. POWER TRAIN:MANUAL TRANSMISSION; ELECTRICAL SYSTEM. There may be clutch mechanism wear. Customer may report that the vehicle does not start or only starts when the clutch pedal is pressed very firmly. The message ?Press clutch pedal to start vehicle? may appear in the instrument cluster.
A3720012039650_22020-08-06. Service bulletin. POWER TRAIN:TRANSFER CASE (4-WHEEL DRIVE); POWER TRAIN:AUTOMATIC TRANSMISSION. This bulletin contains instructions for addressing a leak from the transmission oil pan gasket or transfer case.
