To the National Highway Traffic Safety Administration (NHTSA):Subject: Safety Issue Report: UConnect System Malfunction in Jeep VehicleDear NHTSA, I am writing to report a significant safety concern with the UConnect system in my Jeep, which has been malfunctioning for the past four months. The system's failure to recognize voice commands and manage remote commands compromises the vehicle's safety features, including hands-free calling and potentially emergency assistance services. This issue is covered under warranty, yet despite repeated attempts to have it addressed by Jeep, there has been no resolution.The malfunctioning UConnect system, crucial for safe vehicle operation by minimizing driver distraction, is not responding correctly, indicating a possible hardware or software failure. Given the importance of such systems for vehicle safety and the refusal of the manufacturer to correct the problem under warranty, I am seeking your intervention to ensure the issue is adequately addressed.I believe this could represent a broader safety issue that may affect other drivers and request that the NHTSA investigate the matter further to ensure vehicle safety is not compromised.Sincerely, XXXXX Attached is my husband's email communication chain. Other complaint information will be available from the Jeep internal system. We are not sure if this is an electrical problem. But we reported issues that seemed unrelated up until now whereas a strange smell and electrical malfunctions existed from the moment we purchased the vehicle brand new. It is odd that only select services requiring telecommunications don't work, but they do seem to work to contact Jeep. We mentioned this smell as exhaust or burning smells in the vehicle but were told this is normal essentially and have still not gotten a response from a Technical Team that either doesn't exist or is nor actively addressing the issue. It seems to be electronics involved and UConnect may be tertiary to the issue.

New vehicle with under 4,000 miles was being driven on a busy parkway when the engine suddenly stalled and would not restart. No visible warning lights prior to stall. Incident occurred just past the top of a hill, creating the potential for a rear-end collision. A police officer was called and arrived, parking behind the stalled vehicle with emergency lights flashing in order to prevent a collision. The driver of the vehicle tried repeatedly, 5 or 6 times to use the vehicle's built-in roadside assistance to get help but got disconnected every time before a tow truck could be dispatched. Vehicle was in the middle of the highway for over 20 minutes. Dealer confirmed engine has seized and has to be replaced.

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.
