Volvo XC90 engine failure problems

Filed Oct 1, 2026 · Brakes · CA

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.

Piston rings inside the engine failed due to a known oil consumption issue with this model vehicle. The engine failed while the car was driving 85 mph and consequently slowed down to 15mph on the highway, leaving the owner of the car stranded alone on the highway. Volvo has a known fix for this issue and there was a class action lawsuit for it, but since it was settled, there was no recall. This is, in fact, a dangerous issue that is preventable. Additionally, the sunroof drains also leak. Water frequently leaks down the A-pillar directly onto the Central Electronic Module (CEM) causing unsafe electrical issues and potential engine failure. This was a known issue on other models, but it is also present in this model vehicle. When I tried to fix this under a warranty contract, I was denied by the certified repair shops.

My 2016 Volvo XC90 suddenly lost power while I was driving, requiring me to pull over and have the vehicle towed. This is a documented safety issue associated with a known piston ring defect in 2013-2016 Volvo vehicles equipped with 2.0L and 2.5L engines, which was the subject of a federal class action lawsuit ([XXX] et al. v. Volvo Car USA, LLC, Case No. XXX, filed XXX. No there we NO warning lamps, messages or other symptoms of the problem prior to the failure. I purchased this vehicle as a second owner from Carvana [XXX] — one month after the class action was filed. I was never notified of the defect, the litigation, or any service campaign or extended warranty coverage associated with this VIN, through Carvana nor Volvo. Since the power loss, I have spent $11,543.75 in out-of-pocket repairs (replacement engine, labor, towing). Despite a new engine being installed, the vehicle enters limp mode within one mile of driving. A Volvo-authorized dealer has quoted an additional $19,959.65 in repairs without certifying that the work will resolve the safety issue. Volvo Customer Care has declined to assist, stating their internal service campaign has concluded. I am submitting this safety complaint because sudden, unexplained power loss in a moving vehicle is a significant safety hazard, and because second owners of affected vehicles were never properly notified of the defect. I never knew nor was this disclosed to me before purchase from Carvana nor told to me by Volvo. I was in the middle of nowhere and I was not sure what to do and being a single woman, I was unsafe and scared. What ever this issue is Volvo and the dealer in South Dakota (where it is parked right now) as I had it towed on June 5th, and they don't want to help nor fix my vehicle. I need my catering business vehicle as this is a very concerning for my loss of use for over a year now for my catering part of my business.

*the engine is the part that failed due to excessive oil consumption. *it became a safety risk once it started selecting its own driving speed after dropping driving speed to 31mph on [XXX in Raleigh. *the problem was confirmed by the dealer, Volvo of Cary *it has not been inspected by the manufacturer, police, insurance representatives or others *upon a service visit our technician, Ray Rancell of Volvo of Cary advised that the engine was leaking oil and engine failure would occur if we didn't take care of it so we did to a total of $2879.74 which would keep the engine from seizing. That means we paid to prevent exactly what happened anyway and as I found out later he did not perform an oil consumption test so he had no way of knowing the shape the engine was in but charged for this work anyway. The repair invoice says the customer stated oil leaking on timing belt but that is incorrect. I would have no way of knowing that as the only thing i know about cars is replinishg fluids. We did have to replinish oil often and advised Ray of that but he said it was normal. Thank God I was able to get into the slow lane and prevented any accident but my and my daughter's life was certainly put at risk. There is a known recall for excessive oil consumption which I fould out about later. When I questioned Volvo they said my VIN number was not included in the recall. Clearly, it should have been.

My vehicle was signaling me to add oil every 600 - 1000 miles around 85,000 miles. The dealership charged me for a chemical treatment to stop the oil burning around 90,000 miles. At about 95,000 miles, my engine failed while driving on the interstate. There was no warning light or degradation of power. Suddenly, the engine lost power, went into limp mode and I could not maintain highway speed. The display flashes "Engine Performance Reduced." My SUV is now parked in my yard. I have paid two Volvo dealerships and a Volvo repair shop to inspect it. They reported oil burning, cylinder scoring and spark plug failure. There is scoring in the #3 cylinder and there is also no compression in the #3 cylinder. They further advised me that ALL engines that fit in my vehicle will experience this oil burning issue and the subsequent pathway to failure. I see evidence that this is a known issue with 2.0L and 2.5L Volvo engines between 2013-16. Of particular note is that several other owners have experienced failure in the #3 cylinder. There is an issue of clogged rings causing oil burning. Oil burning leads to damage to internal engine components like pistons, spark plugs, valves and etc..causing engine failure and ultimately engine fires. Oil burning extends into the exhaust system and also damages catalytic converters leading to failure of those components and even fires. I understand Volvo issued Tech Journals to dealerships but, to date, this information has not been published to the consumer that we may be made hole. This is a major design flaw that creates an expensive and extremely dangerous situation affecting numerous engine parts subject to high levels of heat during engine operation. Any of these parts are susceptible to spontaneously combusting during operation and without warning. It is an extremely dangerous situation. However, I see no evidence of a recall on my vehicle.

Vehicle is a 2017 model year of the Volvo XC90 and has the same safety issue in the Quality Bulletin for Recall R29936: Coolant Bleeder Hose (Engine Side), which is for the same make and model but for the 2016 model year. The vehicle has a plastic coolant bleeder hose that can crack and create a coolant leak that drips above the catalytic converter. The coolant accumulates in the catalytic converter heat shield insulation and poses a fire risk in the engine compartment area. The leak can also be small enough to cause coolant to evaporate and off gas into the cabin through the AC, exposing fumes to cabin occupants. The corrective action is to replace the engine side coolant bleeder hose, though this recall did not extend to 2017 model years, in which this same part was used. The same recall R29936 will need to be extended to other model years after 2016 in which the same component or design of component was used.

On September 30, 2025, a 2016 Volvo XC90 T6 experienced sudden engine failure while driving westbound on I-75 (Alligator Alley) at highway speed. The vehicle abruptly went into reduced power mode (“turtle mode”) without warning. This forced the driver to stop on the roadside, creating a serious safety hazard in fast-moving traffic. Component/system that failed: Engine / Power Train. An independent repair facility performed diagnostics on October 6, 2025, including a compression test. Results confirmed that one cylinder had lost compression due to a failed cylinder head. The mechanic attributed this to excessive oil consumption from defective piston rings, a condition documented in Volvo technical bulletins. Inspection: The vehicle was inspected by an independent service center. Photos and test results are available for inspection upon request. The manufacturer was contacted and denied assistance, citing mileage, despite known oil consumption defects in this engine family. Safety risk: The sudden loss of power at highway speed put the driver and other motorists at risk of collision. With no advance warning, the driver was left stranded on a dangerous stretch of interstate. Reproduction: The failure has been confirmed through diagnostic testing and inspection by the independent service center. Manufacturer/police/insurance inspection: The manufacturer has been notified, but no inspection by Volvo has occurred to date. No police or insurance inspection was performed. Warning messages or lamps: Prior to the breakdown, no warning lamps or messages indicated impending failure. The first and only symptom was the sudden loss of power on the highway. Incident cause assessment: Based on mechanic’s findings, the underlying cause is piston ring/oil consumption defect leading to cylinder head failure. This defect is widely reported in Volvo vehicles with this engine and represents a safety-related condition.

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 the federal safety agency to investigate Volvo XC90 coolant hoses for material defects, as this issue endangers drivers through unexpected breakdowns and engine failure.
