   On Wednesday 9/23, I was driving on a residential road and came to a stop sign. When I tried to stop at the intersection my brake pedal seized up and the car would not stop. The check engine light came on. I had to shift the car into park in order to stop the vehicle. I towed it to the dealer and found out today that the brake booster failed.

   This submission supplements NHTSA Complaint #11759206, filed on August 24, 2026, regarding a 2018 Volvo XC90, in order to provide additional relevant information that came to light after the original filing. At the time of the first safety-critical malfunction (in-vehicle warnings including "Transmission Acceleration Performance Reduced" "Gear Lever Locked" and related electrical system symptoms), the service manager at Volvo Cars Brooklyn was able to remotely diagnose the likely cause by telephone, before the vehicle was even towed to the shop, specifically instructing the owner to check for dampness under the driver's floor mat, which was confirmed to be present. This indicates the symptom pattern described (sunroof leak leading to corrosion affecting the transmission, brakes, and electrical system) was already recognized and familiar to Volvo Cars Brooklyn's service staff, not a novel or difficult-to-diagnose issue. Additionally, the owner was informed that multiple other Volvo vehicles were present at Volvo Cars Brooklyn on the same day for repair of the same reported issue. Once arriving at the dealership, the service manager tole us that he had, "Just totaled a vehicle for the same issue." This suggests the underlying defect is not an isolated occurrence, but a broader, recurring pattern affecting multiple vehicles of this platform. This supplemental information is provided to support NHTSA's assessment of whether a safety-related defect trend exists affecting this vehicle platform, consistent with the pattern described in the original complaint and in other publicly available consumer complaints regarding sunroof-related water intrusion on the Volvo XC90.

   The vehicle first experienced a safety-critical malfunction while driving on the highway on August 11, 2026, producing in-vehicle warnings reading "Transmission Acceleration Performance Reduced" and "Gear Lever Locked," along with broader electrical system symptoms, requiring the 2018 Volvo XC90 to be towed to Volvo Cars Brooklyn on August 11, 2026. At that time, dampness was discovered under the driver’s floor mat, leading to the discovery of a sunroof leak and resulting water intrusion. The dealership represented the vehicle as fully repaired and safe to drive. The same safety-critical malfunction occurred later that night, while driving about 90 miles away from the dealership, with the same warnings appearing, confirming that the original repair failed to address the underlying issue. Loss of normal transmission and braking function while the vehicle was in motion directly affected the driver's ability to control the vehicle. The vehicle was towed for a second time on the morning of August 12, 2026, to Volvo Cars Brooklyn, where it was confirmed that module corrosion caused by the original sunroof leak had not been properly diagnosed or corrected during the first service visit, and that this corrosion had disrupted signals to the vehicle’s electrical, braking, and transmission systems. The dealership completed a corrective repair on August 12, 2026, replacing the OFM module and removing water, following the second incident. The vehicle has not been separately inspected by Volvo’s manufacturer-level engineering team. This failure is consistent with a broader, documented pattern affecting this vehicle platform. Volvo has previously issued a Technical Service Bulletin addressing a sunroof-related water leak on an earlier model year of this platform. While that bulletin does not specifically cover the 2018 model year, numerous 2018 model year owners have independently reported the same failure pattern, a failed sunroof seal, often linked to clogged sunroof drains.

   The air conditioning evaporator core has been widely known to freeze and crack on 2016-2021 models of the xc90 which sends toxic refrigerant smell thru the vents. This is a big safety hazard and should be recalled. Volvo knows about this but only does a goodwill repair to loyal customers who purchased the vehicle new and have all service records from the dealership. This is a $4000 repair for everyone else for a manufacturer defect and safety issue

   I am reporting a serious safety concern involving a 2018 Volvo XC90 T8 PHEV. On [XXX], at approximately [XXX] CT, the vehicle experienced a sudden multi-system safety and actual brake failure while in a parking-lot/low-speed setting near [XXX} in Austin, Texas. The vehicle displayed multiple urgent warning messages and indicators, including power steering failure / stop safely, brake/ABS warning, SRS airbag service urgent warning, stability/traction warning, battery/electrical warning, check-engine warning, and tire-pressure warning. The vehicle ended in an irregular/distressed parking position after trying to locate a concrete block to force stop the car due to ABSOLUTE BRAKE FAILURE, E BRAKE SEEMED TO NOT WORK EITHER. The concern is not simply that a warning light appeared. The event involved steering, braking, airbag/SRS, stability, and electrical warnings at the same time, making the vehicle unsafe to operate AND SOMEHOW THE BRAKES WEREN’T OPERATING DUE TO THE LACK OF FUNCITONING. Photos were taken of the warning messages and vehicle position. Prior related history:
This vehicle has prior safety-system history involving SRS Airbag Service Urgent warnings and braking/vehicle malfunction and movement concerns. Earlier review and discussion involved Volvo engineering, VDDM replacement, CAN/network concerns, calibration requirements, voltage/12V battery considerations, software/module updates, and post-repair validation. The VDDM is understood to participate in vehicle dynamics, stability control, brake coordination, and PHEV regenerative/hydraulic brake interaction. Prior documentation also raised concern that intermittent brake, SRS, VDDM, CAN, and calibration issues may not reproduce during a short dealer test drive. Safety risk:
The safety risk is that the vehicle may experience sudden or intermittent loss, degradation, or warning of systems involved in steering, braking, stability control, and airbag readiness. A simultaneous power steeri INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA

   My 2018 Volvo XC90 T8 Plug-In Hybrid experienced a catastrophic, premature component failure of the Electric Rear Axle Drive (ERAD) propulsion system while driving. The ERAD unit suffered a total failure of internal bearings and sensors, completely disabling the electric rear wheel propulsion system and suddenly forcing the vehicle into a reduced-power "limp mode" on the road. This sudden loss of hybrid propulsion creates an immediate highway safety hazard, removing expected acceleration and vehicle control in traffic. Volvo has documented this exact engineering flaw internally under Technical Journal TJ 36665, recognizing a manufacturing vulnerability in these specific hybrid components. However, the manufacturer is refusing to provide remedy or financial cost-sharing to repair this vital propulsion and safety defect, leaving a hazardous, compromised vehicle on the road.

   At approximately 6:30 PM, after normal driving and parking at a local park, our family was unloading children from the vehicle. One child was standing next to the vehicle while we removed a younger child from the rear seat. The child suddenly screamed and stated that he had burned himself. We later determined that he had accidentally come into contact with the exterior exhaust outlet. As we continued walking, we noticed the injury was more severe than initially believed. We took photographs of the burn and later sought medical evaluation. The physician determined that the injury was a second-degree burn due to blistering and provided treatment recommendations. The vehicle was operating normally, and there were no warning lights, messages, or signs of a malfunction before the incident. The concern is that the exposed exhaust outlet becomes hot enough during normal vehicle operation to cause a serious burn from brief accidental contact. We believe the location and accessibility of the exhaust outlet may present a burn hazard, especially to children during routine loading and unloading activities around the vehicle. The vehicle and photographs are available for inspection. The vehicle has not yet been inspected by the manufacturer or a dealer regarding this incident.

    My Volvo's XC90 brakes have failed twice. At around 95,000 miles, my brakes stopped working, and then I had them repair it. They charged me close to $3,500, which they said they were able to cover under warranty, and I only had to pay the deductible, which I don't remember. In less than nine months, at about 104,000 miles, the same problem persists. Both times I was driving the car, by God's grace and luckily, I was under 10 mph. I literally parked and started driving after that, and I realized the brakes weren't working again. I'm just thankful to the Almighty that I was not at 55 or 60 mph on a freeway when the brake stopped working.

    2018 Volvo XC90, VIN [XXX] , 54,618 miles. Original owner. All service performed exclusively at Volvo Cars West Houston (same dealer, all three failures). Volvo Technical Journal TJ 34648.1.2, titled "Prior Approval - Lack of airflow causing poor cabin cooling," is classified as a Product Fix and explicitly lists the 2018 XC90 as an affected vehicle. This TJ required the dealer to submit a Prior Approval report to Volvo Corporate when installing the resistor fix. At 12,017 miles (August 2020), the dealer installed the evaporator resistor per TJ 34648.1.2, Part No. 32241228, under VST Operation 98734-2 — meaning Volvo Corporate has documentation of this vehicle's evaporator vulnerability on file since 2020. At 15,930 miles (March 2021), the AC compressor failed and was replaced under warranty, consistent with refrigerant starvation from the same underlying evaporator leak. The evaporator has now failed completely at 54,618 miles despite Volvo's own corrective measure being applied at 12,017 miles. The current failure (April 2026) includes a confirmed front evaporator refrigerant leak and AC discharge hose leak, documented by dealer borescope inspection showing corrosion on the evaporator fins and visual evidence of refrigerant oil residue at the discharge hose fitting. Dealer repair estimate is $4,406. This is a documented pattern failure across 2016-2018 Volvo XC90 models. Volvo Cars USA was contacted for goodwill assistance and denied the request within 24 hours without meaningful review. Case number [XXX].

    Rear Drivers door (left) fails to latch. Volvo has an updated part for better water ingress prevention, then the part that was used to build the car. The problem is that water enters the moveable window, runs down the metal channel separation gthe fixed and moveable window, and enters the door latch mechanism. This is extremely dangerous, in that the door may appear closed, and the vehicle may allow the driver to move forward or backward, but the door is not latched and can fly open leading to death! This is an issue known by Volvo, hence the updated OEM replacement part, however they are grossly negligent in not reporting or self recalling vehicles for this issue.

    At random times the back doors will not open, from the inside or outside…hit all the unlock buttons and will NOT open. If this is not a massive safety issue, I don’t know what is…. If we get in a wreck and our car is on fire and we cannot instantly get ourselves or our children out quickly that’s a problem… if we wreck on the freeway and we see vehicles coming at us and we cannot quickly exit. This is a problem. For a car company to not address this it is gross negligence… we own a Ford focus it’s been taken in about three times for door recalls, but we never even actually had an issue…Volvo being a luxury car company and choosing to ignore this issue at the expense of the consumer has went on too long! This hasn’t happened only once, has happened sporadically multiple times

    My car completely locked up on the road and came to a screeching stop. This car is known for having the ERAD completely fail and it could have caused it to have a serious accident. It has also caused my car to plummet in value losing over 30k in just 3 years. Now my repairs cost nearly what it’s worth and aren’t guaranteed to actually fix it. It’s terrible. I’m so upside down n my loan due to this issue that they dealerships refuse to help on. The dealership acknowledges it is a design flaw but yet they won’t help. I have an email stating that it is a design flaw

    On 8/20/2025, my 2018 Volvo XC90 T8 suffered catastrophic failure of the Electric Rear Axle Drive (ERAD). The vehicle suddenly developed a loud whining noise from the rear and became undriveable. This ERAD had previously been replaced under warranty at Boston Volvo Cars. On 10/28/2025, Queens Volvo inspected the vehicle and confirmed the failure was caused by improper prior service. Their technician documented that the ERAD housing was likely not properly torqued, which led to transmission fluid leaking over time, sludge buildup, and internal damage to gears and motor. The failure was sudden, confirmed by an authorized Volvo dealer, and the ERAD is no longer serviceable. This created a safety risk by causing immediate loss of propulsion and stability. If it had occurred at highway speeds, the risk of crash would have been significant. The failed component remains available for inspection.

    3 weeks ago we had the transmission module fail on our vehicle while it was being driven. According to Volvo forums, this is a multi-model year, multi vehicle issue for those with sunroofs. Accrding to the dealer in our case, the seal failed, and water runs into the compartment where the transmission module is located, causing it to fail. We had it happen twice, and both times on the highway, with the engine running ragged causing it ot accelerate and then quickly decelerate. There were 3 warnings that popped up-"Gear lever locked," "transmission acceleration performance reduced," and "Parking Brake unaavialble." It happened twice and and was towed to the dealer both times, as it was not drivable-once the vehicle was parked it would no longer move out of park. The first time the diagnosis and module reset was comped by the dealer (Borton Volvo, Golden Valley, MN) and the second time, the transmission module was "dried out," and the sunroof seal was replaced, which was just under $700. It is available to be inspected if necessary. The vehicle was a hazard to others on the road while it was "acting up." Dealer was familia with the issue. No inspection was done other than by the dealer Warning lamps as outlined above

    While actively driving into an intersection, driving on the street and or stopped at a light or at a stop the vehicle will shut off, the lights on the dashboard will sometimes be on, other times go completely black, a notification pops up on the dashboard saying "engine not in P". There is no way I'm aware of to re create this action. My children's safety as well as mine has been put at significant risk and in harms way as well as others due to the severity and nature of this unexpected risk while driving on the freeway, through intersections and in general driving through traffic and busy streets. I've had multiple close calls of almost being hit when the car stopped while I'm driving with my children. The problem has yet to be reproduced by the dealer at this time however we have photos and video of it's ongoing safety concern. It has not been inspected by the manufacturer nor police but is currently at the dealer undergoing inspection. There has not been any notifications or warnings prior to any one of these serious events, the message only comes up when the car is off and won't go.

    The engine coolant bleeder hose in my 2018 Volvo XC90 cracked in the middle of my journey causing a severe coolant leak. This happened in August of 2024 while driving and the engine coolant suddenly started showed warning with low level and the engine started overheating. The vehicle would not accelerate past 20 mph, and the temperature warning light flashed continuously, creating a safety hazard in traffic. The Volvo dealership diagnosed the issue and confirmed that the coolant bleeder on the supercharger is broken and leaking. They replaced the bleeder hose and vacuum fill system. I believe similar issues happened to the 2016 models and a recall was issued for the coolant bleeder hose (part # 32249907-0) to be replaced by Volvo. This has not been recalled for the 2018 models, making it an expensive replacement for me. I urge NHTSA to investigate Volvo XC90 coolant hoses for material defects, as this issue endangers drivers through unexpected breakdowns and engine failure.
