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

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 auct

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 N

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

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!

Fuel smell coming from the vehicle when parkied in the garage. Has been check out twice. 1 st time Infiniti could not find any issue, but told me they were looking into it under engineering review. 2 months later after living with the smell brought it back they had a Infiniti engineer look at it. Now they are telling me they acknowlegde that there is a issue with the crank case ventalation system. Still no fix waiting on engineering review to come out with new bulletin could take up to 3 month. The smell of gas in my garage is a health hazard to humans. They have been complaint of this issue dating back to 2019. It needs to recalled.

The contact owns a 2020 Infiniti QX50. The contact stated that the vehicle was repaired under NHTSA Campaign: 25V437000 (Engine and Engine Cooling) however, other failures occurred.

The contact stated that the underbody shield of the engine guard had detached, allowing road debris to enter the hood. In addition, the contact stated that while attempting to start the vehicle, the vehicle failed to start as intended, with a rattling sound coming from the engine. The vehicle was towed to a local dealer, where the vehicle was lost and misplaced. The manufacturer was made aware of the failure. The failure mileage

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 testin

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 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 w

Car abruptly stalls while driving. Has occurred 3 times. Dramatically increasing a chance of collision. Navigation always gets me lost. Navigation and other screen goes black and restarts while driving. Audio/radio comes on while driving on it's own when I want music off. Touch screen applications like changing radio station, switching screens do not always work. Auto door unlock with the keys do not always work, have to wait many times for the function to work. Most important is the abrupt stalling that jerks my body forward its terrifying!

-display screen completely black, buttons would work, radio would work, heated seats would work, ac would work but absolutely nothing on the screen. I did not bring the vehicle in because I thought 'that was weird' and it would just go away. Upon starting the car the next time, everything was normal. -severe condensation inside vehicle windows. Condensation was so severe that water was actually dripping from my windshield onto the dashboard and dripping from the sunroof onto my seat. -display screen blank again exactly the same as feb incident, this time I did bring the vehicle in and the entire display screens were replaced. -a/c did not work. Was driving gf to airport and she was getting hot due to rushing, the a/c only blew like a fan, it did not blow cold air at all. I tried

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.

1. Collision warning sensor activated while driving in the #1 lane( closest to the cement highway dividers) and aggresively braked and slowed while diving at 77 MPH. Not safe!! 2. Even thou I purposely turn the radio "off" when exiting my car, upon entering my car after a short duration of time, the radio turns "on" without any assistance by me....very frustrating!! Vehicle has been inspected by the local Infiniti dealership....they're clueless and of no assistance or help.

I was going 70 miles an hour on a highway with no cars around me. When the car suddenly breaks and beeped. It was very dangerous. I was in the center lane of a 3 Lane Highway with no one around.
