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.
