Drivers sun visor broke off while driving on November 2023 on a 2021 Jeep. I was driving at a residential area going 30mph. Dealership fixed it and assessed it as a safety issue. I brushed off the incident and considered it as normal wear and tear. Then in April 2024 the passenger sun visor broke off. I was on the interstate driving 70mph. I seldom carry passengers and when I do it's mostly after sunset. In both cases, we simply flipped visor down and it broke off. The roads were smooth both times. I went online to search for recalls but instead found many forums experiencing the same issue and suggesting to buy a 3rd party sun visor repair kit.

The front defroster only blows out of the middle vents, no flow out of the left and right vents, causing issues with visibility in any instance where the window might fog up. I have an appointment with the service department at my local Jeep dealer on 8/02/23. As this is a known issue and there is still no recall to fix the issue I feel a complaint is warranted.

Windshield cracked in the winter at less than 8000 miles due to front window defroster being way too hot. Windshield continues to crack and degrade every time the defroster comes on (automatically with remote start) and has made the windshield unsafe due to impairment of visibility. Jeep denies that there is a problem, though they have been quietly replacing windshields to resolve customer complaints without addressing the safety issue with these.
Windshield defroster does not defrost the edges of the windshield.
1. Water leak and windshield cracked because windshield seal broken. Windshield seal found to be broken or cracked by dealership. 2. Windshield cracked and water leaking into Forward Crash Collison Avoidance Radar housing and onto viewscreen which has quit working. 3. Cracked windshield causing visual impairment.
My windshield has cracked 2 separate times. I got it fixed by safelife after the first, the second just happened today. Both times I never heard anything hit the window and the crack just appeared. I had a jeep wrangler before this one and never had any issues with the windshield. This one is brand new and has been on the road s…

My windshield has cracked 2 separate times. I got it fixed by safelife after the first, the second just happened today. Both times I never heard anything hit the window and the crack just appeared. I had a jeep wrangler before this one and never had any issues with the windshield. This one is brand new and has been on the road since Nov 2021 and now has 2 issues. It leads me to believe it is a manufacturing issue. I work from home and don’t drive very often, when I do it’s highway. I just can’t believe that it has cracked twice.
Backup camera will periodically go black on screen when putting the vehicle into reverse. It had been replaced once under warranty after a certified dealer found it to be “defective” upon inspection. Problem persists even after replacement.

The front defrosters are terrible they only defrost the center part of windshield. Ice builds up making it impossible to see anything. This is a serious problem to all drivers and pedestrians.

3PE24024 · Underhood Fires
Opened Sep 6, 2024 · No close date supplied
Status: open (inferred from source dates) · Steering:hydraulic Power Assist:pump
The Office of Defects Investigation (ODI) has received 9 Vehicle Owner's Questionnaire (VOQ) reports, 1 Death and Injury report, and multiple field reports alleging incidents of engine compartment fires in model year (MY) 2021-2023 Jeep Wrangler and Gladiator vehicles. The majority of the reports describe a fire occurring while the ignition in the vehicle was in an ‘OFF’ state with a suspected origin at the passenger front side of the engine compartment. An ignition ‘OFF’ vehicle fire can result in an increased risk of occupant injury, injury to persons outside the vehicle, and property damage, with little to no warning. ODI has contacted the vehicle manufacturer, Fiat Chrysler Automobiles (FCA), and learned of several thermal events originating at the power steering pump electrical connector in recent model year Jeep Wrangler and Gladiator vehicles. The location of the pump connector is located at the passenger front side of the engine compartment, coinciding with the majority of fire reports known to ODI. ODI is opening this Preliminary Evaluation (PE) to assess the cause, scope, and frequency of the alleged defect. To review the ODI reports cited in the Opening Resume ODI Report Identification Numbers document, go to NHTSA.gov.

ODI is opening this Recall Query (RQ) to assess the severity of the alleged defect in vehicles not included in recall 22V-865.ODI will also assess the scope and remedy effectiveness of the recall. To review the ODI reports cited in the Opening Resume ODI Report Identification Number document, go to NHTSA.gov.

EA23001 · High Pressure Fuel Pump Failure
Opened Mar 17, 2023 · No close date supplied
Status: open (inferred from source dates) · Fuel System, Diesel:delivery:fuel Pump
The Office of Defects Investigation (ODI) opened PE21-021 on October 14, 2021, to investigate incidents alleging a stall/loss of motive power as a result of high-pressure fuel pump failures in certain model year (MY) 2019-2020 Ram 2500, 3500, 4500, and 5500 heavy duty trucks equipped with 6.7L Cummins turbodiesel engines. During the investigation, ODI sought to determine if the related defect allegation was limited in scope to the recalled population. After review of information request response materials from both FCA and BMW, NHTSA determined that sufficient information to identify a comprehensive recall population could not be produced by FCA and BMW.During the investigation FCA filed recalls 22V406, 22E048, 22V767, and 22E087 which include vehicles not identified in the initial subject population by ODI. ODI also received recall 21V586, involving loss of motive power due to failed CP4 fuel pumps on certain BMW manufactured vehicles. An information request letter response received from BMW indicated that failed pumps on their vehicles were caused by an interaction between pump internal components and US market diesel fuel, leading to increased slip and eventual particle-generating wear surface. Additional work will be done to identify whether a similar root cause is associated with the FCA recalled population and if similar wear dynamics occur on pumps supplied to vehicle manufacturers other than those included in the recalled population.ODI has upgraded this investigation to an EA in order to 1) determine engineering specifications of internal pump components that are correlated with pump failure leading to loss of motive power or other safety related hazards, 2) identify vehicle populations equipped with alleged defective pump variants, 3) assess if vehicles equipped with alleged defective pump variants result in an unreasonable risk to motor vehicle safety and 4) gather and review any other relevant information related to high pressure fuel pump failure associated with the subject populations of recalls 21V586, 21V880, 21E094, 22V406, 22E048, 22V767, and 22E087.Review of the above information will allow NHTSA to confirm root cause and recall remedy viability, and identify and evaluate vehicle populations equipped with pump components that may pose an unreasonable risk to motor vehicle safety.The ODI reports cited above can be reviewed at: http://www-odi.nhtsa.dot.gov/owners/SearchNHTSAID using the following complaint identification numbers: 11257550, 11351441, 11361603, 11361616, 11365300, 11365426, 11365858, 11366401, 11372337, 11373793, 11374797, 11376793, 11377871, 11378173, 11384377, 11386063, 11387018, 11399710, 11402550, 11415339, 11418868, 11418870, 11427075, 11434276, 11436807, 11437226, 11437249, 11437273, 11437292, 11437294, 11437394, 11437399, 11437403, 11437405, 11437423, 11437528, 11437565, 11437579, 11437580, 11437590, 11437679, 11437744, 11437781, 11437842, 11437993, 11438006, 11438008, 11438121, 11438138, 11438155, 11438392, 11438629, 11439359, 11439879, 11440397, 11443030, 11446542, 11448163, 11453556, 11458918, 11460558, 11469337
