2020 INFINITI QX50 Engine Problems

I am a [XXX] woman who purchased my first vehicle on December 6, 2024, with 43,000 miles. I have driven fewer than 20,000 miles since purchase, and the vehicle currently has approximately 62,000 miles. Until January 19, 2026, I experienced no issues. I have properly maintained the vehicle and followed all recommended service guidelines. I completed three oil changes during my ownership, averaging approximately every 8,500 miles. Two oil changes were performed by a licensed mechanic, and the most recent oil change and inspection were completed on November 29, 2025 at Legend Infiniti. I have receipts for all services. On January 19, 2026, while driving approximately 65 mph on a four-lane highway in Long Island, the vehicle suddenly went into limp mode and dropped to about 10 mph without warning. This created an extremely dangerous situation with a serious risk of collision. I first brought the vehicle to my mechanic,...

RECIEVE 5 RECALL NOTICE BUT DEALER WILL NOT LOOK INTO THE RECALL. DEALER IS INFINITI OF FIFE IN TACOMA WASHINGTON. MY CONCERN IS THAT THE VEHICLE BREAKDOWN AND THEY SAID IT'S NORMAL WEAR AND TEAR HOW CAN I PROVE THAT.

The vehicle was returned to service and was not declare unsafe In 2024 , the same Infiniti dealer performed maintenance and again returned the vehicle to service without restriction The vehicle has now develop internal engine damage . The dealer is denying recall coverage , stating the damage is due to oil sludge and alleged lack of maintenance . The denial is inconsistent with service history , as the sludge was documented and treated while the vehicle was under dealer maintenance , and dealer performed maintenance continued after that finding. Additionally , Infiniti Consumer Affair stated they cannot assist because the vehicle is in Puerto Rico....

Received safety recall August 22, 2025. Still no remedy or communication. Recall data was refreshed January 19, 2026 reports unrepaired recall with no remedy plan. Is this a continuing safety risk?

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...

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...

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...

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...

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...

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!
