One problem related to transmission not engage has been reported for the 2018 Jeep Renegade. The most recently reported issues are listed below.
On the manual transmission, the clutch seems to not reengage completely (as if you were riding the clutch) causing it to get hot and have a lack of power and a nauseating odor. The problem began abruptly and causes a significant loss of power/acceleration that is extremely hazardous on the roadway.
