2020 INFINITI QX50

The contact owns a 2020 Infiniti QX50. The contact stated that while driving at undisclosed speeds, the vehicle failed to accelerate as intended and lost motive power. There were no warning lights illuminated. No further information was available. The contact received notification of NHTSA Campaign Number: 25V437000 (Engine and Engine Cooling). The vehicle was taken to an unknown local dealer, where it was determined that the timing belt needed to be replaced. The dealer informed the contact that the recall repair was not available. The contact stated that there was an unresolved dispute with the dealer. The vehicle was not repaired. The manufacturer was contacted, but no assistance was provided. The failure mileage was unknown.

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.

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.

The plastic clips on the panoramic sunroof holding the sunshade cover snapped while I was driving causing the shade to rapidly roll up. Note that there was no misuse of the sunroof shade and I wasn’t even using it when this Happened. This seems like a dangerous liability in case it were to hit the driver while on the road or distract them. After looking at my extended warranty I found my dealer does not cover the repair and I have to pay upward of 2k just for the plastic clips. There are no TBS for my vehicles vin on the sunroof rails breaking but there are for rattling and it even mentions issues with the clips but no problem to fix it. There are no lights to indicate this feature is broken on the dash as well.

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.
