2025 Jeep Grand Cherokee

I am filing a formal safety defect complaint regarding an acute, uncommanded deceleration event caused by an unintended Auto Start-Stop system engagement and electrical failure at highway speeds in my 2025 Jeep Cherokee (~22,000 miles). Incident Description: On XXX, while traveling westbound on [XXX] toward [XXX], at approximately 75 mph in normal highway traffic, the vehicle's Auto Start-Stop feature engaged unexpectedly and automatically while in motion. Simultaneously, the instrument cluster flashed and experienced a partial blackout, failing to display the vehicle's speed (MPH) and engine RPMs. This malfunction triggered immediate, uncommanded engine braking / rapid deceleration, dropping the vehicle's speed from 75 mph down to approximately 40 mph within seconds, without any brake pedal application. Risk Assessment & Recovery: After several seconds, the instrument cluster rebooted to normal operation, throttle response returned, and the cluster indicated that the Auto Start-Stop feature was active. I immediately deactivated the system manually via the center dash control to prevent recurrence. While light traffic on [XXX] prevented a rear-end collision, this sudden, uncommanded 35-mph drop in speed presents a severe hazard of high-speed rear-end impact, loss of vehicle control, and chain-reaction collisions on congested freeways (such as nearbY XXX). Current Status: •The vehicle was delivered to Greenbrier Motor Company in [XXX], and checked in with Service Advisor [XXX]. •The dealership has taken custody of the vehicle for electrical/diagnostic evaluation and provided a loaner vehicle. •A corporate inquiry has also been initiated with Stellantis / Jeep Customer Care. This submission is made to ensure federal records document this hazardous powertrain/electrical failure mode for potential defect trend analysis.

2025 Grand Cherokee Laredo Drivers side B pillar is making a creaking sound and popping noise that started now and again and then became more consistent. We have had it at the dealer under warranty currently and they have had the car more than my wife and I. three attempts made and still no permanent fix, though they have replaced the door striker and the manager said welds looked good but still it does not sound right. The passenger B pillar makes no noise at all. Jeep HQ Corporate office under customer service has been contacted twice now. Old case 9749-9837 and new case 9842-0468. I have notified the service manager at the shop and will be contacting them for an appointment for a fourth attempt to get this resolved before filing possible lemon law form.

The vehicle experiences severe drivetrain binding, mechanical clunking, and erratic 4WD electronic timing failure while operating at normal driving speeds. During acceleration (27–28 mph, transitioning from D4 to D5 gear), the automatic 4WD transfer case / front axle disengages abruptly under load, causing an audible mechanical clunk and drive-line shock. During deceleration (31 mph down to 15 mph, downshifting from D6 to D4 gear), the 4WD system forces a re-engagement of the front axle, creating a heavy binding shock and severe mechanical clunk. This uncommanded electronic engagement and disengagement failure creates vehicle hesitation, drivetrain binding, and a potential loss-of-control hazard while driving. The issue is available for inspection and has been documented on video.

1).While driving the message shows up: Vehicle is not in park. Then the motor shuts off (at any speed). This happened several times (I was on my way to take my wife to chemo infusions)! This is very dangerous when driving and caused almost an accident on the highway!!! 2), When turning the motor on, the seat moves into the pre-set drivers position, then moves back again and then the motor shots off. The car can't be driven then for a few minutes.

Car cut off while driving, again. Full dashboard started to flash, warnings, stated that there was no battery, no gas. I was stopped in traffic and managed to pull over and had restart the car. This is the second time that it has cut off while driving . The first time my toddler son was in the car in morning traffic and it cut off. This is an extreme safety hazard for myself, my family and others driving. The entire system failed. It was supposedly fixed before but the problem is still there.
