“There is a module that needs some sort of update I have power but my steering completely went out. All the lights in my dash came on, and my odometer started blinking. Ive read that newer models the 2023 edition also has this problem and has an open recall right now.”

NHTSA complaint #11691462, filed 2025-10

“The dash lit up with all lights and it said SOS Power STEERING is out. I could not turn the wheel. The lights such as my miles was blinking, the seat belt was flashing along with dinging even though my seat belt was on. There has been recalls due to power steering issues but my car isn't on there. It put me and my son at risk for a terrible accident. I have taken it to a dealership. There were no warnings prior to this incident.”

NHTSA complaint #11631019, filed 2024-12

“I experienced electrical issues that resulted in loss of steering and difficulty turning my 2021 Jeep Cherokee Laredo. The steering became very hard to turn, and warning lights were present. This created a safety concern because the vehicle was difficult to control. I took the vehicle to an authorized Jeep dealership in Midwest City, Oklahoma. The dealership diagnosed the issue as a fuse array and attempted a repair. The vehicle remained at the dealership for approximately five days. …”

“My vehicle was experiencing the exact same HVAC/AC issues described in Customer Satisfaction Notification Z33 for the 2021 Jeep Grand Cherokee L. Although the campaign specifically lists my make, model, and year, Stellantis claims my VIN is not covered. I was forced to pay $175 for the same repair listed in the Z33 document (HVAC module flash, Labor Code 18-Z3-31-82), and this should have been covered. Stellantis is refusing reimbursement even though the issue and fix are identical.”

NHTSA complaint #11668070, filed 2025-06

“The vehicle didn’t automatic update of its “UCONNECT” system without warning after stopping at a gas station. Once the vehicle was turned back on after the update was completed there was a light on my dashboard signaling that the forward collision warning system is off. Some other things happened as well such as all my settings were reverted back to factory settings, and the menu screen was in Italian. After online research, it seems that this is a very common problem with the specific model. …”
