Some Jeep Renegade owners report experiencing sluggish hesitation when shifting into gear, which may be attributed to issues with the shift linkage or cables, as well as potential transmission problems with the 9-speed ZF 948 TE gearbox. Additionally, owners have noted rough idle, often caused by vacuum leaks, faulty spark plugs, or weak factory motor and transmission mounts. Furthermore, some owners previously encountered stalling issues that were resolved by replacing the negative battery cable, highlighting the importance of ensuring the battery and alternator are functioning properly to prevent further stalling or rough idling. It is advisable for owners to inspect and address these concerns promptly to maintain vehicle performance.
