ELECTRICAL SYSTEM, ENGINE, FUEL/PROPULSION SYSTEM
Around 530pm At the corner of Briarcliff Rd NE Atlanta Ga and N Druid Hills Rd NE Atlanta GA As I was about to accelerate after the Red Light turned green, my car experienced a significant loss of power. Several warning lights came on, the engine light came on and a warning that said System Default came on. I was almost rear ended but was able to put on my hazards and coast to the side of the road, where I turned the car off and back on. It continued to display the warning and system default message as well as loss of power. I was able to coast into the parking garage at work and park. I am a healthcare worker and my shift ends at midnight. I have a 30 minute drive home and I’m afraid my car may do the same thing-lose power- and that can be catastrophic on the interstate. This is not the first time this has happened. I took my car to Infiniti and they said the recall was cancelled for now. I have two small children that I have to transport in my car and it is unsafe. We need a solution asap!

AIR BAGS
The contact owns a 2017 Infiniti QX50. The contact stated that while driving at an undisclosed speed, the passenger’s side air bag sensor unexpectedly illuminated and failed to turn off. The vehicle was taken to the dealer, where it was diagnosed, and determined that the passenger’s side seat cushion had failed and needed to be replaced. The vehicle was repaired. The vehicle was later taken to an independent mechanic, who provided the same diagnosis and informed the contact that the passenger’s seat cushion needed to be replaced. The vehicle was repaired. The contact expressed concerns regarding the significant price difference between the dealer's repair cost and the estimate from the independent mechanic. The contact’s spouse was concerned that the failure made the vehicle hazardous to drive. The manufacturer was made aware of the failure. The approximate failure mileage was 89,000.

Car recently had an important safety recall that was suspended, my car is a 2019 QX 50 Infiniti Luxe, that recently shut down and had to be towed, infiniti dealership diagnosed the car and says I have all low compressions and that I need an engine, these symptoms were quoted to my service dealership prior that the car hesitate to take off, low pick up when I accelerate, stops out of nowhere at intersections, I was told car performs as it was designed to perform even tho I explained it has like a growling sound, now here I am with an engine failed vehicle that they are trying to charge me 13,000 for repairs, I am still paying on this car and have a balance of 14,000+ owed, the dealership is saying they performed a recall diagnosis and that no debri was found in oil pan, any mechanic should know just because debri wasn’t found in the oil pan does not mean the car is not eligible for recall repairs, especially if the diagnostic test was done too soon, the car is definitely part of the recall but they will not honor that, I only had the car just 3 years as of September 2025, the car itself is only 6 years old, this engine failure is definitely part of the recall and I should not be responsible for this repair, this is a safety hazard for me and Infiniti should be held accountable for this faulty engine.

About 3 months ago I took my car to be inspected for recall Infinity Dealership stated the drained oil and dropped oil pan and inspected for debris on bottom on oil pan however manufacturer has stated engine beating failure happens progressively not all of a sudden I believe the system malfunctioning light I’ve been seeing on my dash is a direct result of something that was missed during recall inspection.

Crest Infiniti staff, including Service Rep Trevor and Manager Randy Nadors, misrepresented Recall 25V437 as "not a safety recall" and claimed repairs were stopped until year-end. This contradicts NHTSA"s designation of 25V437 as a serious safety recall and Infiniti Corporate's confirmation. Their false statements indicate a failure to disclose material safety information and unsatisfactory service, thereby putting consumers at risk.

My vehicle is affected by Recall 25V437. I am already experiencing recall-related symptoms, including stuttering, unusual engine noises, and uneven acceleration. I leased the vehicle through DFW Auto and Services INC, On August 15, 2025, at 9:35 AM, I spoke with Sam in the finance department of DFW Auto and Services INC during a 3‑minute call from 214‑205‑7327. I specifically asked about the recall affecting this vehicle. Sam stated that the recall had been “taken care of.” This was false, as Recall 25V437 remains open and unresolved. The dealership misrepresented the recall status of my vehicle, failed to disclose that Recall 25V437 remained open, and delivered a defective product – a vehicle with a known safety defect that directly impacts usability, value, and consumer safety. On November 18, 2025, I submitted a formal complaint to the Attorney General regarding this matter. This misrepresentation placed me at risk of driving a vehicle with a known safety defect that could result in sudden engine failure or fire. I am requesting NHTSA to investigate the dealer’s misrepresentation and ensure proper enforcement of Recall 25V437. This recall must be remedied at no cost to me. I have contacted: Crest Infiniti 6100 State Highway 121, Frisco, TX 75034 to have Recall 25V437 remedied. I am currently still waiting response from the service center for an appointment to have the engine replaced.

I am submitting a formal safety complaint regarding Recall R25B2 on my 2020 Infiniti QX50. I purchased the vehicle in July 2024 from a dealership in Indiana and currently reside in Illinois. Summary of the Issue In July 2025, I received notice that my VIN was included in Recall R25B2 for an engine-related defect. Infiniti of Orland Park (IL) inspected the vehicle and confirmed that it exhibited symptoms consistent with the recall. My recall/warranty repair was denied because Infiniti claims the engine is “branded” in its internal system. This branding does not appear on Carfax or any public record and was never disclosed at the time of sale. According to California DMV documentation I obtained, the vehicle sat on a California Infiniti dealership lot from 2022 through 2024 before being auctioned. Infiniti later stated that the engine was branded in 2023 due to “lack of maintenance”—a period when the vehicle was under Infiniti’s possession or control. I purchased an Infiniti Vehicle Service Contract (VSC) in 2024 (which has since been refunded), indicating Infiniti’s own retail systems did not flag the vehicle as ineligible. During two prior oil services (January 2025 and the week before the recall inspection), no dealership representative mentioned any “engine smut” or branding concerns until the recall claim was denied. I believe this situation represents a safety and consumer transparency issue. Infiniti is allegedly using non-public internal “engine branding” flags to deny recall eligibility for vehicles otherwise included in a safety recall. Consumers and selling dealerships have no way to access or verify these internal designations through Carfax or public records. As a result, affected vehicles may be excluded from safety recall repairs without notice or recourse—despite meeting all other criteria. Requested NHTSA Actions Investigate whether Infiniti/Nissan is improperly using internal branding to deny Recall R25B2 remedies to otherwise eligible vehicles.

2019 Infiniti QX50 Recall Campaign ID: R25B2 (Safety Recall 2025) Summary of Issue: I received a safety recall notice stating that my vehicle may have an engine manufacturing defect that could cause severe damage or complete engine failure. This poses a significant safety risk. Details: Contacted Infiniti Consumer Affairs on August 28, 2025 (Case #55702324) and my local dealer. Dealer confirmed recall is active but remedy is not available; they refused inspection even if I offered to pay. Consumer Affairs indicated proactive assessment may incur charges unless defect is confirmed, which I find unreasonable given the severity of the issue. No timeline provided for remedy or inspection. No alternative transportation offered. Safety Concern: Driving the vehicle under these conditions could lead to sudden engine failure, increasing risk of accidents and injury. Requested Action: Confirm recall status and remedy timeline. Require manufacturer to provide inspection or alternative transportation until repairs are available.

ENGINE, POWER TRAIN, UNKNOWN OR OTHER
Infiniti has acknowledged that certain vehicles equipped with this engine may experience bearing failures caused by a manufacturing defect affecting the main, A-, C-, and L-link bearings. These defects can result in engine damage or complete engine failure, as outlined in Infiniti’s recall notice. In September 2025, I took my vehicle to an authorized Infiniti service center after receiving notice of the recall. At that time, I was informed that no repair remedy was yet available. I continued operating the vehicle as advised, and no warning lights or performance issues were present. However, on October 16, 2025, the Service Engine Light illuminated unexpectedly. I immediately brought the vehicle to the nearest certified repair facility the following day (October 17, 2025). Diagnostic testing determined that the engine had suffered internal bearing failure, consistent with the known recall condition. The vehicle required a complete engine replacement, which I had to proceed with at significant personal expense, covering both parts and labor. At no time prior to this incident did my vehicle display any warning indicators or abnormal performance. The sudden nature of the engine failure created a serious safety concern and considerable financial hardship. I am therefore formally requesting reimbursement or assistance with the full cost of the engine replacement and associated labor. I have attached supporting documentation, including repair invoices, diagnostic reports, and proof of payment, for your review. Given that the failure directly relates to the known defect identified in the recall, I believe reimbursement is both appropriate and warranted.
