2017 Volvo XC90

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.

The contact owns a 2017 Volvo XC90. The contact stated that while driving approximately 25 MPH, the low coolant level warning light was illuminated. The contact refilled the coolant reservoir; however, approximately one week later, the warning light was again illuminated. The vehicle was taken to the dealer who diagnosed that the small coolant hose was leaking. The vehicle was not repaired. The manufacturer was not informed of the failure. The failure mileage was unknown.

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.

The contact owns a 2017 Volvo XC90. The contact stated that after a rainstorm, there was water leaking from the rearview mirror, which leaked into the vehicle, causing the electrical system to fail. There was an abnormal sound of water swishing around inside the vehicle. The on-call warning and check engine warning lights were illuminated. The vehicle was taken to the local dealer, where it was diagnosed with a cracked sunroof cassette leak. The vehicle was not repaired. The manufacturer was contacted and opened a case. The failure mileage was approximately 147,000.

Was driving and my low coolant light came on. I pulled over and car shut down and coolant leaking all over the exhaust and block of the engine. Crack in the coolant bleeder hose leaving me stranded on the side of the road. I then googled the issue to my surprise it is the same crack point and part that the previous year 2016 model had a recall on for safety as this is a fire risk leaking on the exhaust and this being a flammable liquid. I am just upset as this was a recall for the previous year model and it is happening on the 2017 model with many other people having the same issue. Contacting Volvo and they will not cover this as there is no active recall on this $800 for a $23 part that is a known issue is a problem and the risk of my vehicle catching on fire when I have 5 children In the car is very concerning for a car that is suppose to be reliable. Not to mention the bad front strut problems on these that go out and send you going in the wrong direction on a bump. Hope this gets taken care of due to the risk!

The evaporator core malfunctioned (AC system), resulting in the failure of the air conditioning system. The defective part remains installed in the vehicle and is available for inspection upon request. This issue compromised the vehicle's ability to maintain a comfortable and safe environment, particularly in extreme weather conditions where the lack of a functioning air conditioning system can pose health risks, especially to young children or elderly passengers. The problem has been confirmed by an authorized Volvo service center, where the leak was identified during an inspection. Prior to the failure, there were no warning lamps or error messages. However, the air conditioning began to perform inconsistently several weeks prior to the complete failure. Given the timing of this issue, just beyond the warranty period, and the evidence suggesting this may be a recurring problem in certain XC90 models, and Volvo Customer Care denied any assistance or support in this matter.

There is a belt tensioning failure which means the belt doesn’t snug to your body or engage as you apply brakes. I contacted Volvo North America on 10/31 after visiting the dealer and have not heard back regarding this problem. There is a code which appeared regarding this problem which is why it was taken to the dealership Volvo of Lisle in Illinois. They estimate the cost to repair as approximately $4,000.00 They said the vehicle is out of warranty 5 years from first service date. We believe safety equipment as basic as seat belts are the manufacturers responsibility. This vehicle has never been involved in an accident and would appreciate your help. I can forward copies of the estimate to repair if you require them. Feel free to contact me

The Park Neutral Position (PNP) switch malfunctions. Yes Not a huge safety issue if you are parked in your driveway and cannot start the car. But if you are driving and the if you have the engine auto start/stop engaged the car will unexpectedly not restart and you have to play with the gear shifter to get it started to move out of an intersection or out of the way of traffic! This has happened several times with my wife and myself. I have not had it confirmed by a dealer or service center No No
