2021 Jeep Grand Cherokee L

Owners of the 2021 Jeep Grand Cherokee L report the most complaints around the forward collision avoidance and automatic emergency braking systems, followed by steering and powertrain concerns. On the driver assistance side, owners frequently describe the adaptive cruise control behaving erratically, most commonly, the system reacting unexpectedly during lane changes, either braking abruptly or failing to account for traffic in the new lane correctly. Steering complaints describe a loss of assist or pulling under normal driving conditions. On the powertrain side, owners report transmissions getting stuck and refusing to engage a gear, sometimes requiring a tow. A smaller cluster of reports covers window and door lock switches failing across multiple doors at once, and at least one owner describes an air conditioning compressor that stopped cooling entirely. An isolated report mentions a passenger seat's air bladder inflating on its own overnight and not deflating normally.
