2024 Jeep Wrangler 4xe VIN: [XXX] I have driven 4 other 4xe 2024 in the last two months as rental cars and have noticed my jeep is not performing anywhere near the other four, I have driven. Seems like my jeep isn’t tuned correctly or the engine/transmission has an issue. Engine: -When starting and as engine warming up it shakes the care periodically. There are times when it will shake the car as it heats up, rocking the car slightly and you can hear the engine make a weird knocking noise. -This also occurs when in E-Save mode and charging the battery is selected. The engine does not idle smooth all the time and sometimes runs rough then goes back to normal -There does not seem to be much torque Transmission: -The 1st – 3rd gear shift at high RPM times even when barley giving it any gas. -The transmission shifts down into 2nd gear at around 18-20 mph when gradually slowing down in traffic causing the jeep to slow down quickly and throws you forward. If you catch it during its shift (which is longer than any other gear) it will slam into 2nd and then back into 3rd gear. You lose power as it takes several seconds to complete the shifting. -The gear I feel should smoothly shift into and out of 2nd at around 15 mph, like it does in the cars I rented. oDoes the shift timing need to be remapped or reset? Software update: -The software update pushed on the home screen several weeks ago to update the camera, and some other items has caused my gauge cluster to flash a lot when using CarPlay GPS. In stead of the turn by turn on the cluster it flashes. I continues to have issue and causing me to lose power or significantly slow down and not able to accelerate in Atlanta traffic. Something is wrong with this Jeep brand... INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving in electric mode, sometimes I would lose power. One example is on the freeway while cruising at freeway speeds. I noticed my speed decreases and i have to press the accelerator pedal more than normal. Even after depressing it more than normal, the gauge on the battery power wont move and the speed continues to decrease (charge level can be at 50%, 80%, or lower). It also happens to me after stops at stop sign or intersection. When in EV mode, my light would turn green or its clear to continue into the intersection, the vehicle will barely creep out of a stop to the point that I would almost get t-boned at a T intersection. I have to floor the accelerator down to the floor in order to get the gas engine to turn on (while in EV mode with adequate charge on battery) and violently push me forward. Happens a few times a week both on highway or intersections.

Continued electrical over discharge resulting in battery failure. Problem remains undiagnosed by dealer, multiple engine / transmission / seat malfunction error codes. Hybrid engine does not take over driving as operated. Concerned this may present as a fire hazard for one as electrical systems are not communicating in a hybrid vehicle. Secondary concern that the vehicle will suddenly lose power while driving at put driver and others at risk of accident. This problem has occurred more than three times since ownership. Vehicle has been owned less than 1 month and was purchased brand new. Initial problem occurred within less than 600 miles of ownership. Vehicle starter battery has been significantly discharged since ownership under normal operations. Was initially advised by the Jeep dealership that 'the wrong battery was installed at the factory' and that changing the battery would solve the issue. Shortly after this service (approximately one week), the problem occurred again. Further diagnostics have remained unclear without resolution via the dealer.

Vehicle lost power and shut down on the highway while driving in esave mode

Filed Sep 4, 2024 · Electrical, Engine · GA

The engine is running rough and loses power when it turns on for the first time and speeding up around 6th gear. Also the 2nd gear takes about 3-5 sec to downshift and you lose the opportunity to step on the gas hard or it will slam into another gear. The lose of power and random shifting causes you to slow down and not able to get out of the way or drive well esp. on the highway. The jeep dealer wants to keep the car for 4 days to trouble shoot. No lights or warnings it constantly does this and seems there is a tuning or computer issue. The car only has 8000 miles on it.

Vehicle has experienced a loss of power/throttle response. Also appears to have an issue with engaging and staying engaged in the drive position. At times when trying to place the vehicle in drive the dash indicator will blink "D1" and you have to return the vehicle shift lever to neutral or park and then back to drive to get the transmission to engage and allow the vehicle to move forward. Both issues have occurred while in 2 wheel drive on paved highway as well as in mild off-road conditions in both high and low range four wheel drive modes without the lockers engaged. Vehicle was taken to a dealer on 7/30/2024 and they checked for codes with the only code displayed relating to the collision detection system activation which has occurred while in four wheel drive modes at slow speeds. Vehicle is scheduled for further diagnostics on 8/19/2024 which was the first available service appointment.
