Other Fuel System problem #1

I am reporting a failure of the fuel pump system in my Volvo vehicle, which currently has approximately 60,000 miles. The failed component is available for inspection upon request. The issue was confirmed by an authorized Volvo dealership, which diagnosed the fuel pump as defective and requiring replacement. This appears to be a premature failure given the mileage and proper maintenance of the vehicle. This failure presents a serious safety risk. A faulty fuel pump can cause the vehicle to stall unexpectedly while driving, increasing the risk of a crash, especially at highway speeds or in traffic. Loss of engine power without warning places not only the driver and passengers at risk, but also other motorists on the road. Prior to the failure, the vehicle experienced symptoms consistent with fuel system issues, including difficulty starting and intermittent performance irregularities. These symptoms escalated until the vehicle became unreliable to operate. The problem has been confirmed by the manufacturer’s authorized service center, and the vehicle has been inspected accordingly. No external factors or misuse contributed to this failure. It is my understanding that Volvo has issued recalls and/or acknowledged similar fuel pump defects in other vehicles of comparable models and years. Based on the nature of this failure and its alignment with known issues, I believe this vehicle should be evaluated for inclusion under an existing recall or be subject to further investigation. Given the safety implications of fuel system failures, I respectfully request that this issue be formally reviewed to determine whether a broader defect trend exists that could impact other vehicles. The failure occurred at relatively low mileage and under normal operating conditions, raising concern of a systemic defect rather than normal wear and tear.

Other Fuel System problem #2

Unintentional acceleration. First, I was in line at car wash proceeding slowly ahead as directed in line. Foot on accelerator lightly moving, when car surged rapidly hitting back end of Tesla about 6-8 ft ahead (2/26/26 12:30pm) impact strong enough to push Tesla into truck hitch damaging it front of it as well. Applied brake, but impact was too rapid. Second incident with my Volvo was a month later(3/22/26 about 10:30 am) and my husband was driving. . Made right turn on green light and started to accelerate when it revived and surged forward until applied brake. Dealer could not replicate. No codes but repair shop had to recalibrate after 1st incident and may have lost code on 1st incident(wreck). Now that insurance knows what happened, I don't know if they will intervene. Hopefully. No warnings went off or messages. Airbag did not deploy. I believe that this is an unintentional acceleration, especially occurring twice now. Dealership says car is safe and they will monitor. I guess it means when we have another incident. Hopefully not fatal to us or anyone else. Dealer says it is a transition from hybrid electric to gas. But I have had this car 4yrs10months and this never happened until now. And the transition never has thrown me back in my seat or had the engine rev. The battery was replaced last August because of bad cell and recall on it for fire hazard. Maybe this could have an affect. On first incident I was in shock so thought maybe in hit accelerator instead of break, but when second incident occurred and it was exactly like first except no collision. Thatshow I originally reported to insurance and police as my fault. But that's not true. Now I called insurance to report dual incidents, two different drivers with unintentional acceleration. Sr-1 filed.

Other Fuel System problem #3

My vehicle was recalled for a faulty battery module. I turned the car into the dealer (palo alto Volvo in palo alto, CA) on December 18 and the dealer has not been able to provide any eta on repairs.

Other Fuel System problem #4

My 2021 Volvo Xc90 recharge has experienced multiple hybrid system failures under Volvo's factory 8-year/100,000-mile hybrid warranty, with fewer than 45,000 miles on the odometer. The high-voltage battery modules have failed multiple times, directly related to recall r10312 (NHTSA 25v-179), which identifies a supplier process deviation in lg battery modules creating a risk of internal short circuit and thermal runaway — an acknowledged fire risk. Critically, my vehicle has suffered two actual battery module failures, not preemptive recall replacements. This places my vehicle in a substantially higher risk category than others in the recall population with no prior symptoms. A vehicle that has already experienced the exact failure mode identified in a safety recall presents a materially greater ongoing safety risk. Additionally, my vehicle suffered a complete erad (electric rear axle drive) failure — a known defect that Volvo acknowledged by releasing a redesigned erad2 unit, confirming awareness of this systemic issue. These repeated failures left my vehicle un-drivable and parked at the dealership for more than 6 months, with replacement parts repeatedly placed on backorder, causing severe and prolonged loss of use. I filed a formal complaint with Volvo customer care requesting a vehicle buyback. After months of inadequate communication, Volvo declined to buy back the vehicle or offer reasonable trade-in accommodation. Instead, Volvo offered a nominal monetary concession contingent on signing an nda, which I declined as insufficient given the documented safety risk, repeated failures of a recalled component, extended loss of use, nor out of pocket car rental expenses. I am filing this complaint to ensure my vehicle's actual failures are part of the NHTSA record for r10312/25v-179, and to request NHTSA evaluate whether Volvo's response to owners who have experienced actual failures — rather than preemptive recall repairs — warrants further regulatory scrutiny.

Other Fuel System problem #5

With 2700 miles my Xc90 has the emission control system light is on. The engine noise is considerably louder than normal (being a hybrid the SUV is pretty quiet) and it is not using the electric option.
