2017 Volvo XC90

Vehicle: 2017 Volvo XC-90 Component: Door latch / door lock mechanism Both passenger-side door latches failed within approximately three weeks of each other due to internal corrosion/rust, as confirmed by Volvo diagnostics. The affected doors cannot be opened from inside or outside, including by key fob or interior door controls. This condition presents a serious safety risk, including potential occupant entrapment in the event of an accident, fire, or emergency evacuation. The vehicle has been well maintained, garage kept, and has not been exposed to flooding. Volvo Cars USA and an authorized dealership acknowledged the failures; however, Volvo declined assistance. The dealership offered partial labor coverage while the owner paid for parts to restore vehicle safety. Because this involves a critical safety component and occurred on multiple doors in close succession, I believe this represents a design or material defect, not normal wear, and warrants formal investigation.

The rear door latch/lock actuators on my 2017 Volvo XC90 fail to latch in cold temperatures, making the vehicle undrivable and unsafe. The doors may appear closed but are not secure, creating a serious risk to the driver, passengers, and others on the road; I rely on this vehicle daily to transport my children. The issue has worsened over multiple winters, and on one occasion the doors remained frozen for about four hours, preventing safe travel to work and school. A local independent garage has confirmed this is a known issue affecting XC90 models in cold-weather climates and identified the likely cause as failing or frozen actuators. This can be confirmed online with a simple google issue that it is a sever and prevalent safety issue. Especially with children riding int he back seats. The vehicle has been run with remote start and for extended periods in attempts to resolve the issue, and temporary measures like sprays or lubricants have not helped. The car had to run for 4 hours to be operable and it was only 10 degrees out. The problem has no warning lamps or messages and occurs only in cold weather. The system is available for inspection upon request.

As I was driving, the coolant low warning came on. Luckily I was able to pull over safely at a nearby gas station. I found that the coolant expansion tank was empty. The coolant was leaking from the plastic connector on the bleeder hose and was pooling on the top of the engine. There is a recall on 2016 vehicles for this (Volvo campaign R29936) and looks like many are having same issue on 2017 models also. My problem was exactly as described, the part broke, coolant squirts out all over hot engine parts, system coolant level rapidly depletes. Fortunately, this happened in place that allowed safe stopping.

On November 5, 2025, while driving my 2017 Volvo XC90, I experienced a sudden and dangerous loss of braking assist. When I pressed the brake pedal, I heard a loud hissing noise coming from under the dashboard, and the car would not stop. The brake would not work and the vehicle would not slow or stop unless I stood up and used my full body weight to press it. A licensed mechanic inspected the vehicle and confirmed this is consistent with loss of vacuum pressure from the brake booster/failure of the vacuum brake booster, the component that provides power assist to the braking system. The booster, brake pump, hose from booster to pump and brake pedal clip were replaced, with an estimated cost of $2,858. The mechanic also advised that this failure is not uncommon in Volvo XC90 models. After the incident, I researched similar complaints and found numerous reports on NHTSA and [XXX] describing **identical symptoms—hard brake pedal and hissing sound due to vacuum booster failure—**in the 2016–2019 XC90. For example, one owner reported “hard pedal, no assist, hissing sound behind dash” [XXX] , Volvo XC90 2017 Brakes section, accessed Nov 2025). No warning lights or error messages appeared before or during the event. The problem occurred suddenly and without prior symptoms. This defect posed a serious safety risk to me, my passengers, and other drivers, as it severely reduced braking ability and required excessive force to stop the vehicle. Under other conditions, this issue could easily have resulted in a crash. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The A/C evaporator core in my 2017 Volvo XC90 failed prematurely, cracking and leaking refrigerant. This is a well-known problem among XC90 owners from model years 2016–2020. Repair costs are USD$5k+ because the entire dashboard must be removed to replace the evaporator. This is not normal wear and tear. Volvo has issued multiple Technical Journals (e.g. TJ 35912.1.0 -- attached -- and later revisions) instructing dealers to install an additional resistor in the evaporator temperature sensor harness when replacing the evaporator. This proves Volvo knows there is a design defect causing evaporator cracking and failure. However, Volvo corporate has declined to assist with repairs for my vehicle. Driving without A/C in high summer heat presents a serious risk of heat exhaustion or heat stroke, particularly during long commutes (I drive over an hour each way daily). The HVAC system is also critical for defogging and defrosting the windshield. Loss of refrigerant and evaporator performance can impair defroster operation, creating visibility hazards. The combination of extreme cabin heat and impaired defrosting creates an unreasonable risk to safety, not merely an inconvenience. In addition, right now it costs me just a few hundred dollars to refill my AC system every summer. This is what I've been doing for several summers now. But the Volvo quote to fix this factory defect was over $6k. So that means myself and thousands of others are all incentivized to just fill up R134A and have it leak out, harming the environment in the process. Volvo's refusal to recall and fix this issue is causing this economic incentive. It should be on them to fix their failure, not us. I asked Volvo corporate to goodwill this repair but they declined to do this (see attached).

ERAD (Electronic Rear Axle Drive) clutch failure. Upon depressing accelerator pedal, when in drive modes that rely more on ERAD (Hybrid/Pure modes), the clutch occasionally does not engage correctly, resulting in no power for a full 1-2 seconds, then power kicking in, in full. Not being consistent means not having a good way to anticipate when the problem will arise in order to compensate for it. The hazard came when attempting to cross traffic (to take a left into a commercial driveway), the delay happened, then before the ability to fully "cancel the attempt" (by releasing the accelerator and pressing the brake while still in the turn lane), the power kicked in and sent the vehicle into traffic. The delay-then-subsequent full-power meant that the gap was suddenly significantly smaller when pulling into the oncoming lanes, and attempting to correct for a delay in power meant the possibility of then not having the accelerator down, which could have left me in in the lane of oncoming traffic for much longer than necessary due to human reaction times in addition to vehicle "reaction times" to inputs. This is apparently a relatively common issue on Volvos of this generation, with multiple "ERAD versions" to account for transmission clutch failures within these units, as well as other failures.

I am reporting a safety defect related to the Vehicle Connectivity Module (VCM) in my 2017 Volvo XC90. The VCM is critical for emergency communications, including automatic crash notification and location sharing with emergency responders. This function is vital for occupant safety in the event of an accident. My VCM was serviced at an authorized Volvo dealer in Natick, MA in December 2024 due to intermittent connectivity issues. Despite this recent service, the VCM completely failed in mid-April 2025. When the module fails, the vehicle loses the ability to automatically contact emergency services and transmit its location after a crash, significantly increasing the risk of delayed or absent emergency response. I am aware that Volvo previously issued Safety Recall R39917 for 2017–2019 XC90s regarding VCM software errors that could prevent GPS location from being sent to emergency personnel. Volvo has refused to cover the repair, even though the failure directly impacts a safety-critical system that was already subject to a recall. This failure compromises the car’s core safety promise and leaves occupants at risk in emergencies. I urge NHTSA to investigate ongoing VCM failures in these vehicles, as the repairs have not resolved all safety concerns. Volvo should be required to address these failures to ensure driver and passenger safety.

I am reporting multiple critical component failures on my 2017 Volvo XC90, which I believe represent potential design or manufacturing defects related to vehicle safety and reliability. At approximately 93,000 miles, my Volvo XC90 experienced a battery failure, thermostat failure, which did not resolve the vehicle's engine issues. Subsequently, the dealership diagnosed a failed Engine Control Module (ECM), requiring complete replacement at a cost of over $5,000. The ECM is a critical motherboard component responsible for engine control and vehicle safety operations. Its failure risks sudden engine malfunction, stalling, or loss of power while driving, which could cause unsafe conditions. I am concerned that multiple major component failures, especially in a premium brand vehicle under 100,000 miles and less than 10 years old, represent a systemic reliability issue. These failures occurred despite regular maintenance and responsible usage. I respectfully request that NHTSA investigate whether similar cases exist for 2016–2018 Volvo XC90 models involving premature ECM or engine cooling, electrical, short circuit system failures. I am available to provide service records and additional documentation as needed.
