I burned my right fingers when I went to move the metal sharp gear selector knob,I was trying to reverse and the dial knob was to hot to touch,I had to find a cloth to cover it so I dident burn my hand again, then I was able to move it to reverse and then drive,this very unsafe. My next problem was that in the parking lot the other day I think it was 8/20/2026,I was at a stop sign and took my foot off brake and the car started bucking and almost hit another car driving by,the car is jumping on its own,the salesmen who just sold me the car said this is normal because it’s a turbo,this is extremely dangerous,and my last problem is that there is excessive orange peel on the entire body of the car,and on the hood also,in which is very distracting and takes my line of sight off the road when driving,this is very dangerous in my opinion,all these issues are very serious ,the dealer already knows about the bucking of vehicle because it’s all over the internet,and I submitted a letter to the general manger about the excessive orange peel paint defect,I am confirming toad that I tell them about. Dangerous shift knob heating up and the bucking sudden jolts also,I am calling service dept and Jeep customer service today to report it I will get a case number.
I purchased a new 2026 Jeep Grand Cherokee summit equipped with the new 2. 0l hurricane 4 turbo. The vehicle has a repeatable and potentially dangerous accelerator-response problem. From a complete stop, I can apply substantial/full accelerator input and the vehicle initially provides little or no expected acceleration. The vehicle may begin creeping forward and the tachometer may begin moving, but there is little corresponding engine sound or vehicle acceleration. After approximately two seconds, the vehicle begins responding and accelerating however it is still extremely sluggish and dangerous. The condition has been repeatedly reproduced in both normal and sport modes. I have also experienced delayed rpm increase and delayed transmission response/downshift while already moving. The condition has occurred when attempting to enter traffic and creates a safety concern because the vehicle does not immediately respond as expected to accelerator input. The dealership initially told me the vehicle was operating normally based on diagnostic readings amd that because of the computers and software there is no direct throttle response on these drive by wire vehicles anymore. That is simply intrue. The dealership subsequently had the shop foreman test drive with me in the vehicle. The foreman experienced the condition and agreed there was an issue with the lack of throttle response. I repeated the issue multiple times from stop, ehile turning, and at speed. The dealership is now involving a technical advisor. The dealer has told me that a stellantis service bulletin concerning similar drivability symptoms does not apply to my VIN. I am not alleging that the bulletin applies to my vehicle. I am reporting the actual safety-related behavior because I believe it warrants investigation regardless of whether my VIN is currently included in that service action.
Vehicle was purchased new from a franchised dealer. Six days after purchase, at approximately 105 miles on the odometer, the vehicle experienced a transmission failure while being driven with my family, including a young child, on board (warning message displayed - service transmission, loss of forward motion, harsh shifting, inability to shift gears while driving on the street). The vehicle was taken to the selling dealer, whose service department diagnosed a failure of the transmission valve body. The diagnosis was made and documented by the dealer's service department, and service records exist confirming the failure. The failed component was not on the dealer's possession as part of the repair process; availability for inspection is unknown, as the dealer subsequently replaced the entire vehicle with a new unit rather than returning the original vehicle to me. Prior to the failure, a warning message stating "service transmission" appeared. The manufacturer was notified of the failure through its customer care process. To my knowledge the vehicle was not inspected by police or insurance representatives. Safety risk: a drivetrain failure on a vehicle in its first week of service presented a risk of unexpected loss of motive power in traffic with passengers aboard, including a child.
After 3 months and less than 800 miles the service transmission light came on. While driving to the dealership, the engine light came on, followed by bells and buzzers. The dealership said our transmission valve connector was defective. It’s been there 2 weeks still waiting for the part to come in. We paid nearly 70 thousand for this vehicle and now there’s a transmission issue.
The contact owns a 2026 Jeep cherokee. The contact stated that while driving and making a right turn, the vehicle hesitated and jerked while depressing the accelerator pedal. Additionally, the contact stated that while attempting to accelerate from a complete stop, the vehicle failed to respond. The vehicle was turned off and restarted and responded as intended upon shifting into drive(d). No warning light was illuminated. The vehicle was taken to the dealer, where it was diagnosed with a loss of battery communication with the computer due to a dead battery. The battery was replaced; however, the failure persisted. The contact stated that the vehicle was previously repaired under an unknown recall. The vehicle was taken back to the dealer for a third time, but no further diagnostic information was available. The manufacturer was notified of the failure and advised the contact not to trade the vehicle due to the safety risk. The service manager informed the contact that another repair attempt was required before the vehicle could be considered under the lemon law. The vehicle was not repaired. The failure mileage was approximately 10.
First, after a trip of approximately 100 miles, the vehicle would not advance after stopping at a stop sign. I had to shift from drive to park and back to drive before the vehicle would move. In the second case, again after a trip over 100 miles, primarily on the highway, the vehicle failed to shift out of first gear while the engine revved to over 7,000 rpm when I left an intersection. In that instance a warning light came up on the dash indicating rpms in the red zone. Once again I had to pull over, put the vehicle in park and re-engage drive before the vehicle would drive in a more normal fashion. It was the following day, when I entered the dealership for a service appointment, that the check engine light illuminated and the vehicle did not run smoothly. The service department determined it was a spark plug issue and claims the problem has been resolved. They also said this issue is fairly common on new (2026) Jeep Grand Cherokee models. There is less than 1,200 miles on the vehicle. I feel I was very lucky that the situation in both instances was relatively safe and there was minimal risk of injury, death and/or property damage. I have lost all confidence in the vehicle.
Heavy vibration of entire vehicle when in reverse. Occasional lack of power when accelerating. Issues with the transmission occasionally failing to shift gears.
