2023 Jeep Grand Wagoneer Suspension Problems

Assessment of Ongoing Mechanical & Safety Issues – 2023 Jeep Grand Wagoneer To Whom It May Concern, I am providing a clear, factual assessment of the ongoing issues with my 2023 Jeep Grand Wagoneer, which I purchased for $108,000 and have owned for less than two years. During this time, I have experienced twelve separate mechanical and functional failures, several of which have rendered the vehicle undriveable for prolonged periods. Below is a summary of the major issues that continue to impact the reliability, safety, and usability of this vehicle. 1. Seat / Massage Mechanism Defect (Ongoing for Months) A malfunction in the seat massage system has created a large, hard protrusion in the driver’s seat. This defect has resulted in significant back pain, requiring both urgent care and follow-up medical evaluation. I have now been diagnosed with sciatica, which my physician has indicated is likely related to prolonged pressure and improper spinal support caused by the seat malfunction. Two dealerships have confirmed the issue and ordered the replacement part months ago, yet the part delivery has been repeatedly delayed, most recently to January 6, 2026. This has affected my ability to safely and comfortably operate the vehicle, and has now escalated into a documented medical issue. 2. Suspension Noise During Auto-Leveling The vehicle’s air suspension system produces extremely loud noises during auto-adjustments. This raises concerns regarding the safety and structural integrity of the suspension system. 3. Window Hinge Failure A window hinge has prematurely failed, requiring service intervention. This is not consistent with typical wear for a vehicle less than two years old. 4. Cruise Control Malfunction The cruise control system intermittently ceases functioning while driving. The only way to restore it is to turn the vehicle off and restart it, which presents a safety concern when traveling at highway speeds. This points to a possible electrical or

We the dealership technician had the vehicle for a repair, he was driving it back-and-forth to work like he owned the car and one day He was leaving his home to go to work and the suspension failed so that had to be fixed and that was back on one of the many time it was in the shop. The stop/start engine doesn’t engage for me when I break for me. For me to get it to engage I have to slam on the break as if I was bracing for an accident and then the stop/star engine mode will engage. I think this vehicle has had five clusters replaced in the car, due to the parking sensors, side warning sensors not working. I believe the fifth one went in Dec 2024 once again. The vehicle was in the shop from November 22, 2024 until yesterday DecemberI 2, 2024 when I picked it up. I got home and the parking sensors didn’t beep off and I could’ve crashed it into my garage door and I went through the system and it was already selected to beep but didn’t, then I started getting a message saying that the side warning sensors are unavailable. I put it in reverse it tells me the wipers are off, so maybe all the clusters that they’re making are faulty. The Jeep Retention Customer Service even sent a specialist, technician assistant to the dealership twice or three times to deal with this issue and it’s still not fixed. The dealership Service Center has put in request for answers of how to fix these problems and have had to wait weeks for answers because they don’t know the answers of how to fix the problems with these vehicles and they send a specialist and still the problems still occur they say put in a new cluster a new cluster gets put in the problem still happens. The part is shipped directly from a manufacturer and they have no ETA on that part and my car would still be in the shop, but the Jeep Retention Customer Service Rep had it expedited but the problem is still ongoing. THERE NEEDS TO BE A RECALL ON THIS CAR AND PEOPLE SHOULD GET THEIR MONEY BACK

This is a new 2023 Grand Jeep Wagoneer Series III L with an inline six HO engine that seats eight passengers. After about 500 miles or less, we noticed the vehicle shaking at highway speeds. Since it has only worsened, it has been to the dealership four times for a fix, without a solution. They exchanged the Pirelli tires for a Michelin, which did not fix this vibration error. While at highway speeds, everything shakes; the front headrest visibility shakes a lot, and the water in water bottles in the center console has a funnel effect, which clearly shows it’s a vibration issue, not a bumpy road issue, also, while seated, the floorboard and the seats, motorist, and passenger you can noticeably feel the vehicle shaking; at one point, my wife started to feel sick. As a result, now she only rides in the back seat. This ultra-luxury vehicle has an intense vibration issue while at highway speeds; the roads are smooth, and we tested it across three states while doing a family trip; it's clearly something with the engine mounts, suspension, or a drive shaft that is not well balanced. The dealership told us that they could not do anything because they did not know how to fix it as they drove other vehicles, and some shook too, even worse at around 40mph. They stated this is normal for the vehicle. Well, it’s not normal for a vehicle, but it might be for this model because of poor engineering or QA parts issues. Either way, my vehicle is not safe to drive; with this vibration only getting worse, I fear it will cause a serious accident or damage the vehicle, shortening its life span, and at 120k, this should not be the case. We want what we paid for and want this issue fixed ASAP.
