NHTSA Complaint #11682645 — 2021 JEEP GLADIATOR

Gladiator on 3rd transmission and likely to need a 4th now at 26,000 miles. Each one failed the same way. The second gear in the manual transmission starts occasionally popping out of gear while driving and progresses in frequency over time to the point that it is impossible to keep in second gear at all. This may result in unsafe conditions such as loss of control of the vehicle. Each of my first two transmissions which were replaced were inspected by dealership technicians and the problem found to be easily repeatable. On tearing down of the transmission, pieces of internal components such as synchros were found to be disintegrated. I believe the transmissions were inspected by engineers from Jeep or its parent company though no findings were made available to myself. There were no warnings beyond the gradual escalation of the issue itself. The problem started happening at about 8000 to 10,000 miles on each transmission.
