Service Brakes Problems of Jeep Wagoneer - part 2

The contact owns a 2022 Jeep Wagoneer. The contact stated while driving approximately 35 mph and accelerating on a highway ramp, the "brake and park " warning lights illuminated, and the vehicle slowed to a stop on the ramp. The contact turned off and restarted the vehicle and the vehicle operated normally. The contact stated that the failure was intermittent but persistent. The contact had taken the vehicle to a local dealer, where the failure was not duplicated, and no codes were retrieved. The contact stated that the dealer replaced the battery however, the failure reoccurred. The vehicle was not repaired. The manufacturer was informed of the failure. The failure mileage was approximately 46,000.

The electrical system, transmission system, and electronic parking brake system were all actioned without command. At approximately 9:31am, December 26th, 2023, the vehicle immediately shut down without warning. The vehicle was driving at a speed of 25-30 mph. The gears automatically shifted down and the power steering was immediately disabled as a shutdown sequence began. The vehicle drifted left into oncoming traffic (due to the loss of power steering? and the curvature of the road ahead). Fortunately, there was a parking lot available to the left and the oncoming vehicles stopped due to the lane incursion. With difficulty, the driver steered the vehicle left towards the parking lot. Suddenly, the electronic parking brake engaged automatically. The driver did not engage the e-brake, it was activated on its own. The driver was trying to steer the vehicle without power steering and avoid oncoming traffic. The vehicle came to an abrupt halt once the e-brake was auto-engaged, and the vehicle shifted itself into “park”. The vehicle had electrical power supplied from the battery, but the engine was completely shut off. At this time, the driver noticed a message that prompted to “open hood”. The only other indication that something went wrong was a “check engine” light. The driver opened the hood and found nothing out of place, damaged, or leaking. At this time, the driver attempted to contact towing services, but was not having any success. The driver re-started the vehicle using the “transmission limp home mode”. The “check engine” light was still on. The vehicle needed to be moved from its obstructive positioning in the parking lot. The driver decided to drive the vehicle back home, less than one mile away. The vehicle was repositioned safely, without further incident. The “check engine” light was the only remaining indication of the incident. This safety incident was a potentially fatal accident. A random, complete loss of power and control is unacceptable.

The 2022 Wagoneer (first model of vehicle) we own has had several issues dating back to purchase in 04/2022. The original battery died in 08/2022 when the car had ~3000 miles. The electrical system was to blame in draining the battery dealer said. Dashboard lit up and shut on and off. The dealership ‘repaired’ with new battery. Other various issues with seats and electrical malfunctions have taken place both before/after that. But last night, about 20-30 minutes into a drive, the check engine and battery lights came on. A couple mins later, the ac and volume didn’t work and then the dash lit up with over 10 buttons. At this point, I was attempting to pull over, but I was on a busy road with no where to go. A couple minutes later, the dash starting flashing on and off. At this point, the steering wheel locked up, the brakes no longer worked and the whole car dash and video screen was dark. I was going 65mph at the time with by 12 year old son and 10 year old daughter. I could not move the wheel and had no brakes as we were entering bend in road and semi truck coming at us. I had to make a decision to either run car off road into a field or house or try to jerk wheel. It took all my strength to turn wheel and avoid the semi truck. We escaped a major wreck or death by a matter of inches. Worrisome and scary to say the least. Fortunately after that turn, the road straightened out and I drove until car ran out of speed. Once it stopped (thankfully there were no people or stopped cars or traffic lights when we didn’t have brakes or steering), the car went into park. Flashers didn’t work. This is a reoccurring problem on my car and we have friends who also had a 2022 Wagoneer and the exact same thing happened to them and they avoided disaster too. There is obviously a problem and I cannot drive that car ever again and cannot put my kids back in that car. Also, it took 4 hours for a tow truck to arrive as Jeep didn’t seem to help much. We narrowly escaped death.

Leaks break fluid when parked at an angle (nose facing down hill). Heat seems to be a factor because it leaks more on hot days. The dealer has tried to remedy the problem no fewer than 4 times, replacing many major components. There appears to be a design flaw in the master cylinder area as that is where the brake fluid keeps leaking from. I have to imagine if you keep losing break fluid it is a safety issue and an environmental one.

This vehicle has a persistent brake fluid leaking problem. Anytime the vehicle is parked at a ~ 7% incline, where the front of the car is lower than the rear, the car leaks material amounts of brake fluid. The dealer has tried many times (over 4 times) to fix the issue by replacing all relevant parts… it still leaks. Based on my observations, there appears to be a design flaw in the brake fluid reservoir and the reservoir cap, it can not keep the fluid in the system. The risks arising from the persistent leaks include: 1. ) catastrophic brake failure due to insufficient fluid in the system, 2. ) fire risk, engine compartment has flammable brake fluid places it should not be, 3. ) environmental contamination risk, and 4. ) slip and fall risk from leaving slippery puddles of hazardous material ever place this vehicle is parked on an incline.

Driving normally and instantly, many alert lights came on. Brake booster failed and difficult to stop vehicle. Vehicle engine power decreased. Radio screen shuts down frequently which is less an issue of safety but reflects instability of entire electrical system which seems to cause errors in critical systems such as braking and other safety equipment. Concerns regarding critical malfunctions seem to be mounting in the Wagoneer and will likely result in injury at some point if not already.

In October 2022 our Wagoneer was taken to the dealership due to the radio display turning off and on, the passenger screen not functioning properly or connecting through the hdmi. We were told the issue was resolved after replacing parts in the dash. About a month later the radio screen again turned off while driving. In February 2023, while driving the Wagoneer in the fast lane on the interstate, the power steering went out, the brakes would not work and the vehicle proceeded to shut down. The dash repeatedly displayed different instructions, "press brake and push button to start," "vehicle not in park," "shift p to start," "stop/start restart required," "shift to p then desired gear," and the red battery symbol appeared on the dash. After making it safely to the shoulder, the vehicle did restart. We were blessed not to have been involved in a collision, as we were initially surrounded by commercial vehicles. Luckily, it appears the commercial truck drivers noticed something was wrong and slowed their vehicles, allowing us to move from the fast lane to the right shoulder before our vehicle came to a complete stop. A short time later, we were able to start the vehicle. 30-45 minutes later while driving, the dash and radio screen turned off. After stopping in a parking lot and turning the vehicle off for a bit, we started the vehicle. When placing the vehicle in drive, it moved forward a few feet and the parking brake was somehow engaged on its own. Our vehicle was taken to a nearby dealership for inspection 2 days ago and we have not heard back from them. We did show the service department manager a video that was taken while the shut down was occurring that showed the instructions being displayed on the dash as well as the speedometer showing the vehicle coming to a stop.

On two occasions, the 2022 Jeep Wagoneer series ii completely shut down and locked up while driving at speed. The steering wheel locked, the brakes wouldn't work and the engine and all electrical components went offline. In both cases, the vehicle was uncontrollable as it grinded eventually to a stop. The first occasion put us in a ditch. The second occasion nearly hit a construction worker. Children were onboard both times. After the first incident, we were able to get the vehicle to start again after a couple of hours. With all warning lights on we drive it slowly back to the dealership. They were unable to reproduce the problem and said that it needed a lot of software updates which they performed. Four months later it happened again. This time it could not be started and it was towed to the dealership who also has not been able to get it to come online. Less concerning from a safety standpoint is that it occasionally won't wake up after being parked. Sometimes opening the hood and slamming it shut gets it to wake up.

Abs lock up and collision avoidance system (blindspot sensor) failures - the vehicle has been serviced unsuccessfully 5 times now for shaking and vibration on the highway, software failures and blind spot collision avoidance sensor failures. Twice since I picked it up at the dealership on Saturday 9/17 (5th visit), the abs has noted a system failure on the dash. It also shut down the collision avoidance system several times after noting a blindspot sensor failure. However, today after it noted the abs failure, the brakes locked up the rear tires while braking. I reached out to Wagoneer on Saturday, and again twice today by phone and once by email to the rep at fca and have not gotten a return call or email.

As I was pulling up to a red light, the vehicle threw itself into park and completely stopped and would not move. I was unable to put gear into drive. Thankfully, I was not going at full speed. After a couple minutes, I was able to put my foot on brake to restart the car. At this point, the engine and battery light were on as well. My fear is what would have happened had the brake auto-engaged at full speed or the highway? there were no issues with this prior to this happening. It has been taken to dealership for repair and has been escalated with a star case to get additonal engineer input. Given the dangerous nature of what occured, I wanted to report now even though I'm not sure what the resolution will be to fix it.

I leased a brand new 2022 Jeep Wagoneer. On August 5, 2022, day 5 of having the vehicle it had a major safety incident. While I was driving the vehicle through an intersection it came to a very sudden and extremely aggressive stop with no warning. The stop was so sudden and extreme that my daughter and I thought that we had been hit by another vehicle, but there were no other vehicles around. After the abrupt stop in the middle of the intersection, the Wagoneer started beeping repetitively and it would not allow me to move out of the intersection. Luckily no one was behind us and I was able to get the vehicle out of the intersection. After the incident I had the vehicle towed back to the dealership and it has been there ever since. Due to the abrupt stop I ended up going to the doctor the next day as my neck, shoulders and lower back were very sore. I am now terrified of this vehicle and I cannot trust it. The dealership says that there is nothing wrong with it and therefor they cannot fix it. After the incident happened I immediately drove it to a parking lot. When I got to the parking lot I turned the vehicle off and when I tried to turn it back on the emergency brake was locked up and I could not drive the vehicle. After several attempts I was finally able to get the emergency brake to release. On day two of having the vehicle I was driving on the freeway with both hands on the wheel and the vehicle started beeping and braking and telling me to put both hands on the wheel, even though they were. There were no other cars close to me at the time and this was startling and very distracting.

Today 30jun2022 my wife had a forward collision. She t-boned a Hyundai sonata on the passenger door the Hyundai’s side airbags deployed and the jaws of life had to be used to get the passenger door open. My wife’s speed was about 5-10 mph it was in a parking lot. None of the safety features activated. There was no fcw, no visual or audio warnings, no brake jerking or braking at all. The front collision sensors failed, which may have assisted in preventing this accident. My vehicle is at a collision center waiting for an estimate to get fix, my insurance company has been notified. My vehicle will be available for data pull or inspection. No malfunction lights or warning lights were on prior to this accident. Problem has not been reproduced or confirmed by anyone.

The first instance I was pulling out of the driveway. When I got to the end I tried to turn my steering wheel and it was completely locked. The alert started going off to service the lane assiatiance. I couldn’t move the tires at all. I turned the car off and re started it multiple times to try to get it to unlock. After about 5 times it unlocked but still said to service the lance assistance. Called dealership they made an appointment 2-3 weeks out to look at it. Two weeks later driving at 35-40mph alert goes off that brake system needs to be serviced the car kicked on the parking break within seconds and steering wheel locked. I had two children in the car. We feared for our lives. Once pulled over the car was kicked into 4wd low on top of all the other things. Called dealership and they sent me to voicemail. Didn’t return call for hours. After restarting the car multiple times I was able to drive it to the dealership. I could only imagine how bad this could have ended up. Still no word on what exactly happened. I’m currently in a loaner.

On 3 occasions over last month the emergency parking brake has engaged while vehicle was in motion. Twice at low speed below 10 mph and one at approx 20 mph. The incidents caused near rear end collisions on 2 occasions.
