What stands out
No new NHTSA powertrain complaint has been filed on this vehicle in over 9 years — the issue may be aging out of the active population.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering powertrain on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
During service and repair requiring removal and replacement of a crankshaft bolt and/or crankshaft damper, achieving proper torque of the crankshaft pulley bolt is critical. Incorrect torque may allow the bolt to loosen resulting in the timing gear breaking and engine damage. Replacement of the bolt is critical to the repair and accurately following the installation procedure in the Workshop Manual (WSM) Section, 303-01 is extremely important. The bolt torque procedure can be found in the crankshaft front seal removal and installation procedure or in the engine assembly procedure.
full bulletin at NHTSA ↗Some 2015-2016 vehicles equipped with 6F50/6F55 transmission and built on 2-Nov-2015 and through 1-Feb-2016 may exhibit no reverse, 3rd and 5th gear with diagnostic trouble codes (DTCs) P0715,P0717,P0756 and/or P2701. This may be caused by the direct clutch cylinder/tone wheel (7F283) inadvertently forcing the snap ring out of position resulting in damage to the direct clutch hub (7G384). Service part (7J250) complete rotating 3-5-R clutch module is now available. Refer to Workshop Manual (WSM), Section 307-01. For claiming, use causal part 7F283 and applicable labor operations in Section 7 of the Service Labor Time Standards (SLTS) manual.

This may be due to small debris causing the VCT solenoid to stick. Before attempting any component diagnosis or replacement of the VCT solenoid, refer to Powertrain Control and Emissions Diagnosis (PC/ED) pinpoint test HK11 to cycle the affected VCT solenoid 10 times to attempt to clear the debris. For claiming, use causal part 6M280 and applicable labor operations in Section 10 of the Service Labor Time Standards (SLTS) Manual.
