| Engine And Engine Cooling problems |
The system that starts the vehicle, called a igs failed yet again. This failed at 700 miles in downtown chicago on the street blocking traffic. Now several months later today going on a trip and the vehicle dies in the middle of the street blocking traffic. Was unable to restart the vehicle again. Attempted to contact Volvo customer service and was on hold over 25 minutes without talking to someone. Tried to find a way to put vehicle into neutral to safely move out of the way, but this vehicle has no way to manually overrride it. It posed a safety risk and could of easily caused an accident.
1. When the air condition is turned on there is knocking/banging/thumping noise. It starts with a whinning noise and then gets thumping noise and then starts again with a whinning noise followed my a thumping noise. It can go over 15 to 20 mins and then stops and restarts again. Yes, it can easily be reproduced. 2. The whinning and thumping noise while the car is driving can cause a safety issue where something could explode (the way it sounds) or air condition can simply not working as we approach summer. 3. Yes, its been reproduced, I've sent them the videos, I was at the dealership to reproduce and they acknowledge there is an issue. Weaver brother Volvo had created an internal case to Volvo technical assistance, case number: rts-us831535. The reply was they are aware about this issue and they are investigating it. The issues seems to be on the expansion valve and they are still investigating it. This was dated August 6th, 2024. 4. No warning lamps or messages or other symptoms. June 26th, 2024. The issue was reported to dealer around July, 25th 2024.
We drove this vehicle to a family event in chicago. We pulled the vehicle out of the parking garage and pulled into a downtown street in front of a hotel to load the vehicle up. Once the family was loaded the vehicle up the car would not start it had 700 miles when it failed. We were stuck on a busy street trying to start the car. I called roadside assitance and someone came out with a jump pack, but the battery was not dead. I was in the pouring rain trying to figure out what was wrong. They did hook a computer up to find several faults in the computer. It did also indicate a left turn signal fault. Also talking with roadside assistance the agent said that was the 2nd call he had with no start issue. Finally it did start but the check engine light was on the whole trip home, had to cut our trip short and drove as far as we could in fear the car would not restart. It kept coming back with the left turn signal fault and did not shut off the car even pumping gas in fear of not restarting then all of a sudden with cruise control on the car just jerked itself amd almost pulled us off the freeway. Now it has been at the dealer all week researching forums this seems to be a common issue.
I am reporting a serious and ongoing safety defect involving my 2024 Volvo Xc90. The vehicle has experienced intermittent unintended acceleration, intermittent loss of safety and alert systems, and false obstacle detection that triggers unexpected braking or steering input. These events occur randomly and without warning, and are not tied to a specific driver, key, driving condition, or user behavior. At times, the vehicle accelerates on its own without driver input. At other times, the vehicle detects objects that are not present, causing the car to suddenly stop while reversing or swerve to avoid perceived obstacles that are not actually in the roadway. These events occur unpredictably and create a risk of collision with surrounding vehicles, pedestrians, or objects. During these occurrences, safety systems and alerts may become unavailable or inoperable, leaving the driver without audible or visual warnings. Audio alerts and system feedback have also stopped functioning during these events, further increasing the safety risk. The vehicle has been brought in for service approximately 8–9 times for various concerns, including these safety issues. Despite repeated service visits, the problems remain unresolved. Restarting the vehicle sometimes restores functionality, but the defects continue to recur unpredictably. This vehicle is used to transport young children, and these failures present a significant risk of serious injury or death. The unpredictability of the unintended acceleration, false braking/steering, and loss of safety systems makes the vehicle unsafe to operate. I am submitting this complaint due to concern for my family’s safety and the safety of others on the road, and because the manufacturer has not resolved the defect after repeated attempts. These issues have occurred since we received the car in September 2024.
