Infiniti
Qx30

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 NHTSA 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 NHTSA 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. . .

The contact owns a 2018 Infiniti QX30. The contact stated that the check engine warning light was illuminated. The vehicle was taken to an independent mechanic, where the diagnostic trouble codes P052E71 and P053A-00 were retrieved. The mechanic determined that the crankcase ventilation system intake valve had failed. The mechanic also informed the contact that the vehicle was a Mercedes-Benz vehicle that the Infiniti manufacturer had rebranded as an Infiniti vehicle. The mechanic confirmed that the engine was a Mercedes-Benz engine. The dealer was notified of the failure. The contact attempted to purchase the part from the dealer, but the dealer provided the incorrect part. The vehicle was not repaired. The contact stated that while driving and coming to a stop, the vehicle stalled intermittently. The contact was able to restart the vehicle and continue driving. The vehicle was not repaired. The contact related the failure to Mercedes-Benz Campaign Number: MC-10241531-0001. The Mercedes-Benz manufacturer was notified of the failure, but no assistance was provided.

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 National Highway Traffic Safety Administration (NHTSA). 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.

Hello, My 2018 Infiniti QX30 slips into neutral while driving on the road at high speeds and without any warning. The message on the dash is vague “Service required. Do not shift gears. Visit Dealer.” I almost got into an accident more than once while driving the vehicle as low power to the vehicle accompanies this when it happens. I had absolutely no problems with the vehicle leading up to the first occurrence. In fact, I bought the car with less than 10k miles on it from Infiniti directly, where it was a fleet loner vehicle and well maintained. My car today has 56,000 miles and it is only a 2018. Two months and three car shops later, the issue remains unresolved. Infiniti said at first this was just a dead battery. A day later the issue resurfaced, where I also received a transmission control error. My service tech at Infiniti admitted that it is 90% Mercedes under the hood and they only have flowcharts to diagnose the issue. They recommended replacing a steering control column for $2k and could not answer me when I asked what that has to do with the error. I pulled it out for a second opinion and have confirmed nothing mechanical with the transmission, it is electrical. A quick google search for “Infiniti QX30 Service required do not shift gears visit dealer” yields an unprecedented number of complaints on forums of a widespread issue involving the transmission control unit for this vehicle. This issue needs to be looked at from a governing authority and my attempts to speak with the dealership about the issue has fallen on deaf ears. I learned the hard way that from 2017-2019, Infiniti collaborated with Mercedes on this vehicle and 90% of what is under the hood is Mercedes. It is the sister model to the Mercedes GLA who experienced similar issues, and the 2019 Mercedes GLA recalled their models for the same transmission control unit failure. A Google search for the same 2017-2019 era with Mercedes GLA yields starkingly similar forums from those owners.
