2020 INFINITI QX50 Engine Problems

I received notification from Infiniti there was a recall for engines failing in the model I drive. I promptly took my vehicle to the dealership, and they confirmed there is metal shavings engine and Infiniti refused to replace the engine. An independent review was done by Infiniti and even though the dealership agrees engine needs replaced Infiniti refused. I am attaching invoice and pictures attached of oil pan confirming metal shavings are present.

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.

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.

I experienced loss of power while on the interstate and at that time I was unaware of what the issue was until I received a Recall regarding the engine. I often have my grandson [XXX]) who sits in the back seat of my 2020 QX/50. I went into the Infiniti of South of Atlanta, Union City, Georgia 30291 and I was informed by my Service Representative (Mrs. Dyamond Cobb) on September 12, 2025 @ 11:00 a.m. that this Recall has been suspended. I was given info to reach out to Infiniti Consumer Affairs Department and also to submit through on line a complaint to www.safercar.gov and I am submitting this info on line as a means to document that I am having serious concerns. I am making payments on a vehicle that could cost me and my family our life! In addition, the dealership is definitely NOT ACTING ON BEHALF OF THE CUSTOMER WHATSOEVER! I will SUE should this vehicle loose power in the stream of ongoing traffic or on the interstate, this is my only vehicle and no one is willing to assist with repairs KNOWING THERE IS AN ENGINE ISSUE and a bearing failure may cause a break in the engine block allowing hot oil to be discharged increasing the risk of an ENGINE FIRE! This is a SERIOUS SITUATION and I SHOULD NOT BE FORCED TO DRIVE AN UNSAFE VEHICLE THAT I CURRENTLY MAKE PAYMENTS ON!!!! LAW SUIT INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The vehicle's engine light turned on. The engine light remains on, and frequently the Malfunction and System fault See Owners Manual will display. When the malfunction message appears all the traction lights are also turned on. The RPM's in the vehicle are very accelerated, and it's difficult to drive the vehicle. The vehicle will also produce a very heavy smog smell. I took the vehicle into the retailer several times and nothing was done. The manufacturer is also not taking responsibility and stated the issue is unrelated to the engine bearing recall.

I own a 2020 Infiniti QX50 that is included in NHTSA Recall 25V-437 for defective engine bearings that may cause sudden engine failure. My VIN has been confirmed by the dealer as part of the active recall. I have already noticed intermittent shaking at idle and a grinding sensation during acceleration, which are early warning signs listed for this defect. I am worried these symptoms indicate my engine may be starting to fail. My Infiniti dealer told me they “see the recall as active,” but that it is on hold and they cannot inspect or repair my vehicle at this time. They also stated they cannot provide me with a loaner or rental vehicle in the meantime. I believe this puts me, my family, and others on the road at risk because engine failure could occur suddenly while driving, leading to a crash. I am nervous to continue driving the vehicle, but I have no safe alternative since Infiniti has refused to provide a replacement vehicle until repairs are available. I am requesting NHTSA to investigate this delay and Infiniti’s refusal to provide a safe alternative vehicle while recall repairs are unavailable.

Pulled out into an intersection with limited visibility. Once I got into my lane I observed a car behind me that I had not seen. I tried to accelerate to avoid being hit. My car began making a knocking sound with loss of power. The other car went around me on the shoulder to avoid a collision. Infiniti of Birmingham (Alabama) says that one of the bearings in the engine spun and there is metal shavings in the oil pan. They say I need a new engine with only 68,000 miles. They are “unsure” if Infiniti will warranty the cost of repairs. Absolutely ridiculous! Please help!
