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 vehicle engine will fail while driving. The electronics reflect the vehicle is still running. Restarting is not immediate and is difficult. This is a known problem that Volvo recalled for 2019/2020 Xc90s. Volvo will not diagnose and repair under goodwill despite my repeated attempts.
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.
On Monday April 29, 2024 I started my car and immediately a warning signal on the dashboard read engine low performance , and the dashboard went black and the engine cut off. The car was then towed to the glen cove Volvo. After a diagnostic I was informed the following needed to be replaced - fuel filler pipe 2) fuel pressure low fuel indicator 3) the aforementioned replacements will require calibrated software update. . I bought this car brand new and I am the only owner and it has only been serviced by Volvo. This car only has 59, 300 miles. I researched the problem online and noted it was a common problem with the. Same make and year of my car and could not understand why there is not a recall for my car, by Volvo for this issue no matter the milage. I came across correspondence on the internet from jason guidi referencing service action s29843 - fuel tank filler pipe insert was manufactured out of specification for only t8 engines. I reached out to Volvo car USA customer care and inquired about them covering the cost of the repairs and also informing them that this problem is not only affecting t8 engines. I just received a response for my concern stating they are sorry they can not assist me with this matter. I cannot begin to express how sadden and disappointed in the corporation, to experience their lack of compassion and. Concern about their product after I spent thousands of dollars of my hard earned money on this defective car. I have no faith in Volvo and no longer feel safe driving this car. I will tell all my relatives and friends of my experience to save them from Volvo's lack of concern about their customers' safety. This is clearly no wear and tear. There are multiple posts on the internet. There's a case of replacement at 10,000 miles, another case where it was replaced and failed again and the dealer is requesting the owner to pay. This this not right. There should be a recall for the entire system when it fails. -clearly defective.
