2022 JEEP GRAND CHEROKEE 4XE Lane Departure Problems

After starting 2022 Jeep Grand Cherokee 4Xe, multiple warnings displayed on dash including: service power steering, service electronic stability control, blind spot alert unavailable service required, and rear braking assist unavailable. The ignition was fully turned on and after shifting into reverse, there was no power steering which required extra effort to turn the steering wheel. The power steering was out for approximately 20 minutes. After restarting the car 20 minutes later, the power steering and blind spot alert was back. A check engine light persisted. After taking to Auto Zone to read check engine light, there was no readable code. The warnings have since went away. The vehicle had 2,497 miles on it at the time of this occurrence which was on June 9, 2023 at 10:18 am.

My vehicle has a faulty front camera system that began at around 1800 miles. When driving, multiple lights will illuminate on the dash. The cruise control, blind spot monitoring, lane keep system, and emergency automatic brakes will shut off. It has been in the shop off and on since May 13,2022. Dealership has been replaced multiple parts, but is unable to get camera system to recalibrate and function properly. Car manufacturer, Jeep, has gotten involved and can not seem to figure out what is wrong either.

Upon starting the vehicle, multiple dashboard lights came on alerting total loss of power steering system (EPS). This also triggered lights related to forward collision warning, lane departure warning, and lane keeping assistance. Vehicle was nearly impossible to steer out of driveway.

Upon startup power steering was disabled and the console message "power steering available service required". Blind spot detection and lane departure also showed as in-op. Wheel was very hard to turn. After traveling a few hundred feet I determined that the car was not safe to drive. After two vehicle restarts the problem cleared. If this happened at speed, in traffic, a serious accident is likely. Dealership is unable to look at problem for weeks. THIS IS A SERIOUS SAFETY ISSUE WHICH REQUIRES IMMEDIATE ATTENTION FROM NHTSA!

I drove the car in the morning with no issues for 45 mins. Later that day I started the car and three warning messages appeared-- SERVICE POWER STEERING, ACTIVE LANE MANAGEMENT UNAVAILABLE SERVICE REQUIRED, & REAR BRAKING ASSIST UNAVAILABLE. There were no previous warnings or messages. The car was not safe to drive because I could not turn the wheel easily at all. When I called the dealership they told me I would have to have it towed in, they had no loaner car for me and that they may be able to look at it on Feb 27th! This happened on February 14th. Completely unacceptable.

Power steering unavailable service required messages pops up steering becomes very tough to turn

Power steering failed while vehicle was operating at highway speeds. After several ignition restarts power steering was restored. Several auxiliary safety systems failed at the same time.

Advanced brake assist / emergency assist issue - while highway driving, during a sunny day and with no cars for at least 1 mile the system engaged the emergency brake as if it detected an eminent accident. This was at highway speeds so caused some commotion in the car. Once safely stopped in a rest area I turned off that system. The next day the active lane management system stated it needed service, that later went away. Moreover when the brake pedal is depressed the peddle pulses, leading me to believe the rotors are warped. This suv only has 3300 miles on it. It is scheduled to go to the dealership next week

Power steering failed while driving. Blind spot detection failed. Third electrical issue since purchased in February 2022. First issue car would not start due to key fob transmitter issue. Second issue. Car would not start due to electronic fuel injection issue.

June 30, 2022 purchase receipt of vehicle. Did not begin using Active Lane Management until August, approximately 800 miles on odometer. These problems came up repeatedly. 1. Yellow warning light came on: Electronic Stability Control 2. Yellow warning light came on: Electronic Stability Control Off 3. Yellow warning light came on: Service Forward Collision 4. Yellow warning light came on: Active Lane Management 5. Instrument display text = Active Lane Management (ALM) Unavailable Service Required 6. Active Lane Management is now intermittent 7. Instrument display text = Blind Spot Alert Off 8. When driving early morning before sunrise and going under multiple underpasses the driver instrument cluster camera came ON and showed a red spot warning of obstacle under the underpass – however no obstacle was there Warning lights and alarms continue to happen for the above. Fort Collins Jeep service technician claims the root problem is a crushed cable part number 68510744AE located in engine compartment. Dealer has my vehicle, waiting for new cable. I don't know if this is the root cause or if other things are wrong. I posted these found problems on the forum on https://www.jeepgarage.org Other Jeep Grand Cherokee Trailhawk owner also said all those problems are happening on his identical vehicle.

From around 100 miles the active lane management started to fail. After few visits to dealer and attempts to calibrate front cam, problem persists, so Chrysler didn’t know how to fix it. After a month waiting for a “tool” to fix it, power steering disconnect. Car back to dealer to avoid a safety accident. After a month i was advised that both failures were cause by a damage rack and pinion that needs to be replaced and test to see if that’s the reason for the failure as explained by the service advisor from Autocentro Chrysler at Caguas Puerto Rico. Iam still waiting.

I was driving down the road doing about 35 mph and suddenly I lost power steering and car jerked to the right. Power steering light, forward collision control, lane assistance, traction control and blind spot warning lights all came on, and a message appeared on my dashboard to have them all serviced. I took my jeep to the dealership I purchased it at in April and they are inspecting the cause of the problem. This is the second time my lane assistance and forward collision have had issues, and the dealership was unable to find the cause the first time. This is first time for power steering, blindspot and traction control.

With 173 miles on the vehicle, I went to start the vehicle and the power steering, electronic stability control, blind spot monitoring, and lane assist lights all went on. The power steering did not work and I was unable to back out of my parking space. I repeatedly turned the car on and off and the lights persisted for at least an hour. After an hour, all lights went off and I was able to drive the vehicle. This could have been extremely unsafe if this had occurred while the vehicle was in motion. This also was problematic as I was stranded in a parking lot late at night. I immediately took it into the dealer and they cannot reproduce the problem and I am driving a loaner as I do not feel safe in the brand new vehicle. No warning lights came on prior to this problem appearing.

There is an issue that according to a document that the dealer gave me and is related to Rear Camera Component Fault Stored In The Radio (Code e B21 7A-9A) They say they have no solution to the issue. When placing the change of the vehicle in reverse, the radio does not project any image, it is a high vehicle and the visibility is somewhat poor.
