2021 Jeep Wrangler brakes problems

Filed Sep 28, 2026 · Brakes, Electrical · CT

Manufacturer corporate and its dealer network are failing to provide a safe, timely remedy for a vehicle subject to high-voltage battery fire recalls (Recall 68C / the federal safety agency Campaign 25V‑741) and a power steering fire recall (Recall 21D / the federal safety agency Campaign 21V‑363). The vehicle has an active check engine light, a disabled hybrid propulsion system, and has now suffered a catastrophic electronic brake booster failure on a college campus, rendering the brake pedal rock-hard like compressed air and leaving the vehicle unable to stop normally. This is a direct, recurring safety failure of Diagnostic Trouble Code DTC C0580-00 (Brake Booster Motor Circuit Low), which was officially documented by a franchise dealer in June 2026. The vehicle also has an extensive history of severe manufacturing defects, including an extraordinary 72-day out-of-service period at a dealership in Miami, FL for a disintegrated rear axle bearing that destroyed the differential housing, alongside advanced structural body rust on hinges found to be unsafe. The manufacturer was formally notified of this active safety emergency and loss of vehicle utility on Sunday, September 27, via email and corporate phone logs, but failed to respond or secure the vehicle. We are formally demanding an expedited manufacturer repurchase/buyout due to total loss of vehicle utility, structural housing conflicts under 'park outside' directives, and severe physical safety liability.

The forward collision/emergency brake engages when it is not needed, necessary or appropriate, and even when the brake pedel is already being pressed. I have adjusted the sensitivity of the emergency braking and forward collision system and I still have this issue.

I have had a brake problem since September 2025. The symptom is a hard brake pedal that does not stop the vehicle at low speeds. There is a similar problem with other Wrangler models that do have a recall issued. It was related to a software update around the same time my problem started. I have had it back to the dealer (Hoover CDJR in Summerville, SC) at least 3 times. At the last visit, they said that they acknowledge there is an issue but Stellantis does not know root cause or have a repair. The problem does not cause a diagnostic code. Not being able to stop reliably in low speed situations include dangers in parking lots, my driveway, stop signs and lights. I have been lucky that I have not made contact with another vehicle or pedestrian yet but it has been close a few times. I fear it is a matter of time before the luck runs out.

While driving at highway speed on November 11, 2025, my 2021 Jeep Wrangler experienced a sudden and complete electrical failure without warning. A “Battery Saver Mode” message appeared, and within seconds multiple safety systems began shutting down. First Failure: While driving on the highway and exiting, the vehicle abruptly lost power steering, ABS, stability control, airbag system, exterior lighting, dashboard displays, and engine power. Multiple warning lamps illuminated at once. Steering and braking became extremely difficult, creating an immediate safety risk. I was able to coast to a stop and park. The vehicle then appeared stable and the messages cleared. Second Failure: After restarting the vehicle, the warning reappeared. While driving on a major high-traffic roadway, the vehicle experienced a total electrical shutdown in active traffic and would not restart. Third Failure: A towing service attempted to jump-start the vehicle; it briefly powered on, illuminated nearly every warning light, then immediately shut down again with the radiator fan running at full speed. The electrical system continued to collapse and the vehicle required a full tow. Inspection and Diagnosis: The dealership confirmed a complete alternator and charging system failure at approximately 36,419 miles. This failure occurred at only 4 years of age, which is unusually early for an alternator or charging system failure. The vehicle’s original battery also failed unusually early (at only 2.5 years old) without warning, which may have been an early indication of a charging system issue. The vehicle is lightly used, garage-kept, never off-roaded, and regularly maintained. The sudden loss of steering assist, braking assist, airbags, lighting, and engine power at speed and in high-traffic areas created an extreme safety risk for myself and others. This appears to be a premature electrical system failure and may relate to broader charging system concerns reported in similar vehicles.

I have a 2021 jeep wrangler and the brake hose went on the driver front side. Mopar product ID is 68307451AH. I have called numerous dealerships and Mopar themselves. They informed me this hose is on backorder for over 841 jeeps, and they are unable to get this across the US. Knowing how many jeeps are needing this hose, is it possible to get a recall on it due to the fact it is imperative to fix right away? I've been trying to find a replacement or an alternate but no luck. This is my only mode of transportation and don't want to keep driving my jeep as it continues to veer to the right due to the faulty hose I'm experiencing.

Received regenerative braking must be serviced notice, followed by loss of motive control. Push accelerator, would not accelerate and actually rolled backwards, multiple notification lights came on, car started to move after 5 seconds, happened again. pulled over to turn on/off car, car would NOT turn on. tried several times and resolved to get it towed. After 5 min, tried one more time to start the car and it did turn on. Functioned normally. Drove to dealership and dealership diagnosis is nothing wrong, dealership now working with Chevrolet engineers.

After taking my jeep 4xe in for the 95B recall I drove around 50 miles and the check engine light came on. Once home vehicle would not turn on or charge. Error on dash said “charging system error.” Next day the vehicle would turn on be experience extreme slowness after stopping with bursts of acceleration. The accceleration and breaking system were extremely jerky and I felt like I didn’t know how the car would respond when accelerating which was dangerous.

I was traveling on the [XXX] on Sunday [XXX] and while started smelling brakes and I got off at the service area and pressed on the brake pedal and the vehicle wouldn’t stop. I had no brake pedal and just heard a clicking sound. There were people everywhere and I didn’t want anyone to get hurt so I had no choice but to drive the vehicle towards a yellow pole which did stop the vehicle but I have been told after the car was towed to a shop that there is an error code B22A9 and believe it was caused by some ecu failure of some sort. The vehicle is in really bad shape and airbags also didn’t deploy. I would like this to be investigated as I would not feel safe in this vehicle if it’s repaired and returned to service. It is a 2021 Jeep Wrangler 4xe and I am aware of issues being reported with the battery but nothing for this problem except for other mentions on the internet on owners having similar problems intermittently. The jeep will be towed to Pohanka Jeep in Salisbury Md. There wasn’t any warning lights. I give permission for the vehicle to be inspected at anytime. I feel this vehicle is a danger to the public safety being it was just serviced and inspected by a Jeep dealership 2 weeks prior and the brakes suddenly fall and now there’s a code with something to do with an ecu or electronics having to do with the brakes failing. Could have been killed in the accident or seriously hurt if I hadn’t exited off the road and used the pole to stop the vehicle.
