2018 Jeep Wrangler Brakes Problems

My wife and I were at a stop light behind a box truck in our 2018 Jeep Wrangler, about 15 feet between us. I had slowed to stop and had my foot on the brake. All of the sudden the Jeep reved up (idle increase), did not see the tachometer, and with my foot on the brake accelerated into the box truck in front of us. When it started to accelerate, I pushed the brake peddle to the floor to stop the Jeep but it did not do a thing. I see 2 problems her: 1. The acceleration when stopped 2. The brake did not hold. There were no injuries or damage to the box truck. We were able to drive the Jeep about 20 miles to the dealer we bought at. It is ow being worked on in the body shop. The Jeep dealer technicians did a computer check on any codes that were activated, but unfortunately all after the fact.

The front right brake caliper on my 2018 Jeep Wrangler was installed upside down from the factory, with the bleeder screw located at the bottom of the caliper instead of the top. The vehicle has been serviced exclusively at authorized Jeep dealerships since new, with no prior front brake work, confirming this was a factory assembly defect and not the result of repair or modification. Because the bleeder screw is positioned at the bottom, air cannot be fully purged from the hydraulic system, which can result in incomplete bleeding, reduced braking performance, uneven pad wear, brake drag, or brake fade. This condition compromises the ability to properly service the braking system and may negatively affect braking effectiveness, creating a potential safety hazard, especially during emergency braking. The defect was discovered during routine inspection when brake performance and wear were evaluated (12-11-25). Photographs and dealership service records are available documenting the inverted caliper and confirming no prior disassembly.

The contact's son owns a 2018 Jeep Wrangler. The contact stated while driving 25 MPH and pulling into a parking lot, the vehicle felt like one of the front tires was not rotating. The contact was able to pull into a parking space. Upon inspecting the vehicle, the contact noticed that the driver's side front tire was not rotating. The contact and a bystander noticed that the driver's side front tire was not rotating because the front brake caliper was protruding through the rim. The contact's husband arrived at the scene, removed the tire, and zip tied the caliper to the frame, and the vehicle was driven to the residence. The vehicle was taken to the dealer, where the brake pads, rotors, and the calipers were replaced; however, the failure persisted. The vehicle was towed to the dealer, where it was diagnosed that the front brake lines had rusted internally, causing the brake lines to collapse. The dealer informed the contact that the failure prevented the brake fluid to reach the brakes, which remained close to the rotors and had burned out. The dealer determined that the front driver's side brake line, rotors, calipers, and the brake pads needed to be replaced. The vehicle was not repaired due to the cost. The manufacturer was not notified of the failure. The failure mileage was approximately 90,100.

My ABS module has failed. Should be a simple fix however Jeep does not have this part available to be purchased. After doing a lot of research into this part it is a Mopar only part and there are thousands of people trying to find this part. This part is a vital part to the ABS system and is causing a lot of people to have to drive without it. Something needs to be done to ensure the safety of everyone that is going through this issue.

The parking brake randomly failed. It was working as designed, and then the next time I went to use it the lever had zero resistance and would not hold the vehicle. I am currently looking at getting it repaired but have to park it in gear to keep it from rolling away when parked (6mt).

My Jeep only has 85,266 miles on it and my pistons/ calibers are locked up, resulting in my cailbers, rotors, and brake pads to all be replaced. This job is projected to cost me over $1,000. My car is currently undriveable.

ABS module failure. Been waiting almost a year now for one, but apparently it’s not a priority to Chrysler and their engineers. It’s going to cause an accident one day and when it does, Chrysler is going to be writing a fat check to your truly.

My local Jeep dealership in Hampton, Va (Winners Circle) believes the ABS control module has failed. While in drive my Jeep would not move forward, the hazard lights would not turn on, the analog speedometer failed to display speed, and power steering is lost. Several lights are illuminated: check engine light, service electronic stability control, and service shifter. The shop foreman (Ryan) and the service manager (Wesley Ward) have confirmed these issues via diagnostics and during multiple test drives. To my knowledge my ABS control module has not been inspected by anyone.

On Dec. 31, 2021, we discovered the left rear brake had "frozen" the brake pads to the rotor, causing it to drag and smoke. My wife was alone in the car at the time. We managed to limp it to the mechanic and got it replaced. On Feb. 8, 2022, it happened again on the front right wheel. This time she was again alone, 2 hours from home, and it smoked so severely she thought the car was on fire. We got it towed to the garage and this time, with a history developed, we got the other 3 calipers replaced along with the parts they ruined. There is no doubt that her safety is at risk with faulty brakes, whether they freeze or fail to grab. The problem WAS confirmed by the mechanic and he showed me how he confirmed it. He fixed it; no other entities inspected it. FCA US LLC did verbally acknowledge brake problems with that model. Wheel drag and a "burnt" smell started in December, 2021; cause discovered 12/31/21. No other prior warnings.

I have had an issue since the vehicle was 6 months old, When applying the brakes, the pedal is low (half way to the floor), not a good feeling. When I do a quick pump, the pedal comes up to safe, responsive level and I get a good safe stop. I don't tow much, but i occasionally tow a small boat, I then don't feel safe at all. I have had it in to the dealer no less than 6 times for the issue and they claim all is ok. I have also paid to have an independent shop look at it and they do find it a problem and even a fix as when they pinched off the front hoses, the pedal was right up top. The last time at the dealer I was told that Jeep does realize that they have an issue but cannot supply replacement parts as they are needed for the cars being built...PLEASE HELP!
