When I started the car and backed out I was alerted that the power steering had a failure and lane departure warnings also. Power steering was not working. Left car for an hour and when I restarted it, warning light was off and steering worked again. Random power steering failure is extremely scary.
Power steering and lane keep assist have failed 3 times already for a new vehicle with less than 5k miles on it. Driven to/from work only.
The power steering and adaptive lane control system repeatedly fails. Loss of power steering makes the vehicle harder to turn. This problem was reproduced by a dealer and supposedly corrected by way of software update. This problem has not been corrected and continues to reoccur following the software update. The lamps for the power steering and adaptive lane control system appear when the systems are not working.
The vehicle lost both power steering and lane keep assist during normal operation. The mechanical fall back steering still works, but that requires significant more force to turn the steering wheel. The issue went away next time I started the vehicle.
Occasionally start car and receive alert on dash stating the electronic power steering is unavailable and that lane management is unavailable. Vehicle has already been to dealership for another recall but it appears that the current issue still remains.
Came out from an event with my family, tried to start my car. Wouldn’t start. When it did start a bunch of lights same came on. Power steering unavailable, as well as active lane assist needs service.
What component failed: power steering & lane management. When component failed: 01/19/2022 at approx. 6:45am car available for inspection?: yes details: while driving from home to work this morning, the instrument cluster displayed an error message "power steering unavailable service required" and a red warning light with a steering wheel and exclamation mark above it. I was traveling at approx. 55mph on the interstate. Because the power steering failed, the active lane management features also malfunctioned. Safety impact: I was driving on the interstate at a high speed. Fortunately I was on a straight-away and had time to react for an upcoming turn/bend in the highway. Loss of power steering made it difficult to change lanes, merge, and make turns. This decreased safety by making it more difficult to control the vehicle. The lane management feature also malfunctioned and decreased safety. This features warns me if the car is crossing into another lane and also provides steering assistance to course correct when the driver doesn't respond fast enough. Because power steering and lane management failed, I had difficulty turning the vehicle and maintaining safe position in my lane, especially on curvy and high-speed roads. Inspection/reproduction of issue: the vehicle is currently at the dealer where it was purchased for inspection by the service dept. This issue has not been reproduced on this particular vehicle. However, this issue was confirmed and reproduced on another Grand Cherokee l I purchased in November 2021. The current vehicle I am reporting the issue for is a replacement car because the vehicle purchased in November 2021 also had the same issue with the power steering, lane departure and lane management.
The power steering is failing randomly on this new car with only about 8,000 miles. It mostly happens when it is colder and first thing in the morning. A message appears that says power steering unavailable, service required. It also gives another error message that the lane departure assistance is not available, service required. I took the dealership, they claimed to fix it, and the next day, it had the same issue. They now have it and claim that only a software update can fix it. When the power steering is in a failed state the vehicle is harder to drive and does not have the lane assistance available.
At 1321 miles power steering went unavailable while driving, restarted car and it was still unavailable. Car now has 1700 miles and have had the issue 7 times. Dealer can not get me in until Feb 15th, 2021. Which is unexceptionable. With no power steering other safety features are unavailable, like cruise control, lane senors and other. I’m making this claim hoping for a full recall on this issue. Many others having the same problem.
Dear NHTSA, I am submitting a complaint regarding persistent power steering issues in my Jeep Grand Cherokee l. The recurring problem, specifically the "power steering unavailable / alm unavailable" error, remains unresolved despite repeated attempts to address it through service appointments. This issue is concerning, and I believe it poses a safety risk that requires urgent attention. 1. Component/system description: the power steering system in my Jeep Grand Cherokee l consistently displays the "power steering unavailable / alm unavailable" error. 2. Safety concerns: the unresolved power steering issue has created significant safety concerns. The sudden unavailability of power steering functionality affects the vehicle's maneuverability, posing a risk to both the driver and other road users. 3. Dealer response: I have brought this matter to the attention of the dealership during multiple service appointments. However, a satisfactory resolution has not been provided. The unavailability of loaner vehicles during service appointments has further exacerbated the issue, as I rely on my car as my sole mode of transportation. 4. Documentation: I have documented the issue with screenshots of the error messages, providing clear evidence of the recurring problem. 5. Seasonal limitation claim: disconcertingly, I was informed that a resolution could only be pursued during the winter season. This limitation is puzzling and raises concerns about the effectiveness of the proposed solution. 6. Prevalence of the issue: a cursory online search has revealed that many other Jeep Grand Cherokee l owners are experiencing similar power steering problems. This indicates a broader issue that requires thorough investigation and resolution. I am willing to provide any additional information or collaborate in further investigations.
Lane keeping assistance fails and disengages mid trips. The vehicle is then allowed to drift to other lanes without correct or alert.
