On XXX, at about 8:45 AM MT, my 2018 INFINITI QX30 (77,152 miles) suddenly lost all mobility on XXX in the [XXX]/[XXX] area during rush hour. The vehicle had started normally and driven about 9 miles with no warning lights or starting problems. Because traffic was stop-and-go, my recollection is that I had manually disabled Auto Stop/Start. I stopped normally with traffic. When traffic moved again, I released the brake and attempted to accelerate, but the vehicle would not move. Multiple warning lights appeared and I could not restore it to a drivable condition. The vehicle remained disabled in an active highway lane for about 40–45 minutes. It could not move under its own power, and a roadway incident-response vehicle accompanied by police had to push it to the shoulder before it could be towed to an authorized INFINITI dealer. There was no crash or injury, but the incident created a serious traffic safety hazard. The dealer found no DTCs and reported no freeze-frame data. Testing confirmed intermittent starter engagement; at times the starter solenoid would not engage. The dealer diagnosed an intermittent starter/solenoid failure, and the auxiliary battery tested “marginal.” However, the dealer has stated that it cannot confirm the starter failure caused the original I-70 loss of mobility, so the highway-disablement cause remains unresolved. The dealer recommends starter replacement so the vehicle can be restarted, road-tested, and further diagnosed. I have asked the dealer to consult INFINITI technical support regarding the unexplained loss of mobility, absence of fault-code/freeze-frame data, possible relevance of the auxiliary battery/Start-Stop system, and further testing. The original starter remains installed and available for inspection. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The rear subframe on my 2018 Infiniti QX30 experienced a structural failure at approximately 39,000 miles. The vehicle was inspected by an authorized Infiniti dealer, who confirmed failure of the rear subframe, a critical structural and safety component. This failure created a serious safety hazard, including risk of loss of vehicle control. The vehicle was deemed unsafe to operate. The failure occurred under normal driving conditions and without warning. A rear subframe is not a wear item and should not fail at this mileage. This appears to be a potential manufacturing or design defect affecting vehicle safety.

I am submitting a safety concern regarding the headliner in my vehicle. The rear portion of the headliner has detached and is sagging downward. As shown in the attached photo, the sagging material obstructs visibility through the rear window, significantly reducing the driver’s ability to see behind the vehicle. This creates a dangerous situation, particularly when reversing, changing lanes, or monitoring traffic approaching from the rear. The obstruction compromises rearward visibility, which is a critical safety function. I believe this issue presents a safety defect that could increase the risk of a collision and endanger both the occupants of the vehicle and others on the road. Requested Action: I respectfully request that the federal safety agency investigate whether this is an isolated incident or part of a larger defect affecting similar vehicles. If found to be systemic, a recall or mandatory repair program should be considered to ensure driver safety.

I am reporting a serious manufacturer defect in my 2018 Infiniti QX30. The headliner has detached and is sagging, obstructing rear window visibility and presenting a potential distraction while driving. This impairment significantly reduces rear visibility and has created an ongoing safety risk, especially when changing lanes or reversing. Infiniti Consumer Affairs has acknowledged the defect and its safety concerns but has only offered partial repair coverage, which I have refused on the basis that no consumer should bear any cost for a safety-related manufacturer defect. The defect is not due to misuse, damage, or wear, and the vehicle is otherwise in good condition. This issue has been reported to multiple regulatory agencies. I am requesting that the federal safety agency investigate this matter as a potential safety hazard and evaluate whether it qualifies for a recall or manufacturer accountability. Vehicle Information: Year: 2018 Make: Infiniti Model: QX30 My vehicle is available for inspection although inspected by the dealership and they reportedit as CRITICAL. . .

I am writing to express my concerns regarding a malfunction in my vehicle, specifically related to the airbags and the steering angle sensor or possibly the steering wheel itself. Over the past year, I have noticed a significant change in my vehicle's performance. Initially, I began hearing a constant clicking sound coming from the steering wheel or its vicinity whenever I make turns, particularly noticeable when I reverse to leave my apartment. Shortly after this sound started, I discovered that my horn is not functioning, which prevents me from alerting other drivers or signaling my presence on the road. This has made me feel unsafe while driving, as I have had several close calls with other vehicles. Due to these issues, I sought mechanical assistance in addition to my regular maintenance. My car has been at the auto care shop for over a month, as this is their first encounter with this problem. They have proposed several solutions, but they are not confident that any of them will completely resolve the issue. I believe this malfunction poses a risk to both myself and others on the road, and I am seeking assistance from the federal safety agency. Prior to the onset of the clicking sounds, there were no warning signals, but I did notice an airbag warning light had appeared. I am concerned about the potential for the airbags to either deploy unexpectedly or fail to deploy in the event of an accident. Fortunately, I have not yet experienced a situation that required their use. I will attach the documents from my mechanical visit. The car is still at that location and is available for inspection upon request. I appreciate your attention to this matter and hope to receive guidance on how to proceed. Thank you.
