I am filing this complaint to report a seemingly common ongoing and worsening transmission issues in my 2015 Jeep Cherokee, which persist and have become significantly worse after receiving the U90 recall update and a subsequent TCM/PCM software update offered by Jeep. My vehicle shifted regular before the update After the update, the vehicle began exhibiting: ¢Harsh and delayed shifting ¢Sudden jerks and gear hunting during low-speed driving ¢Uncommanded downshifts ¢Severe hesitation from a stop, especially at intersections or in traffic ¢Loss of power under throttle, with unpredictable shifts These symptoms make the vehicle unsafe in daily driving ‘ especially in traffic or at intersections ‘ as it often fails to respond predictably when attempting to accelerate or shift gears. The transmission behavior feels erratic, and software updates have not resolved the issue. Despite the U90 recall and repeated visits to the dealer, the transmission continues to perform poorly and poses a safety concern. Other owners have reported similar issues post-recall. Jeep has not issued a full recall for these problems beyond software updates, which clearly do not solve the underlying mechanical or calibration issues Resolution Sought: I urge NHTSA to: ¢Investigate post-U90 transmission behavior in the 2015 Jeep Cherokee ¢Consider a formal recall or service campaign for the ZF 9-speed transmission (9HP) due to persistent performance and safety problems ¢Require Jeep to provide a permanent fix for affected owners
