The first time happening I was driving on the interstate going about 70 miles an hour in the dark, the car completely shut down with no warning I was able to coast then tried to restart the vehicle and it started. I was able to get off the road and to my destination. The second time this happened, it was 5am in the morning getting on the interstate going about 40 miles an hour I got to the end of the ramp and merged into traffic again no warning the car shut down. This time the vehicle would not restart. I was able to coast to the shoulder with traffic approaching on me. Had to wait for a tow in the dark by myself.

May 14, 2025 I am submitting this complaint regarding my 2017 Jeep Wrangler Unlimited Sahara, which has only 60,000 miles and has already required several major repairs that raise serious safety concerns. To date, I have had to replace three brake calipers and the emergency brake, at a cost of over $2,500. The calipers were seizing, and the emergency brake would not release properly, both of which posed clear risks while driving. I understand through forums and peer discussions that other owners have faced similar issues. In addition, my vehicle now has an oil leak that will cost over $700 to repair, and the windshield washer fluid hose burst, requiring another replacement. These repeated failures on a relatively low-mileage vehicle suggest underlying quality and reliability issues. I believe these concerns warrant review, particularly the safety-related brake defects. I respectfully ask the federal safety agency to investigate whether these failures are part of a broader pattern that may justify further scrutiny or a formal recall. Thank you for your attention.

Vehicle had a DTC P0302 and a misfire at idle. Upon diagnosis cylinder #2 was found to have 80psi compression which is significantly lower than compression in all other cylinders. Cylinder head was found to be bad. This vehicle only has 61,303 miles. There are many owners complaining about the same problem and FCA indicated they fixed the head issues in 2013. They have offered an extended warranty for 2011-2013 vehicle but the issue still exists. The warranty should be expanded to include more year models.

ABS module failed 2 years ago. No traction control, no cruise control, no stability management. This part has been on backorder for 2 years and affects many years. Issue started intermittently about 3 years ago while driving, now the vehicle is extremely unstable in wet conditions. Dealership has diagnosed and said to check back every few months for a solution. Additionally the plastic oil filter housing has been replaced 2 times in 2 years at a cost of $1,200, the second install was covered by parts warranty. Dealers won't install the metal version available on other years that do not have a cracking issue, aftermarket metal versions are available but dealers won't install them.

My seat belt is always loose and i have to jam it back in place all the time. I noticed an oil spot on the floor of my garage and it looks like it's the oil cooler housing that is bad. Both of these items are recalled but my vin shows It's not.
