There are 14 owner-reported engine complaints for the 2019 Subaru Outbackin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
The Tumble Generator Valve (TGV) assembly within the intake manifold failed on my 2019 Subaru Outback at only 48,000 miles causing catastrophic engine failure. This is a critical engine component that is expected to last significantly longer than the vehicle's current low mileage. The premature failure of this part triggers engine warning lights and disables key driver-assist safety features (such as EyeSight), creating a distraction and potential hazard while driving. This indicates a material defect in the TGV components used in this model year, causing catastrophic failure well before reasonable service life expectations.
The contact owns a 2019 Subaru Outback. The contact stated that while driving approximately 45 MPH, the accelerator pedal was depressed, and the vehicle hesitated and almost stalled. The failure was intermittent but caused the vehicle to stall on several occasions. The check engine warning light and the low oil pressure warning lights recently illuminated. The vehicle was taken to a local dealer, and the contact was informed that oil was leaking from the upper and lower oil pan, the head gasket, and other engine seals. The contact was aware that the vehicle was included in NHTSA Campaign Number: 21V587000 (Fuel System, Gasoline). The contact researched and became aware that a failure of the fuel pump could lead to other failures with the engine oil seals. The contact stated that the fuel pump had been ordered; however, the vehicle was not yet repaired. The manufacturer was informed of the failure. The failure mileage was approximately 82,000.
I have 2019 Outback Subaru. I just paid 5k to get the cam carrier fixed in November, now i am being told my motor is going out and i have to get additional work done to the cam carrier. I got my car in October of 2019 with 3/miles, my car has a little of 91k miles. Why do i have to come out my pocket almost 10k with this car being a 2019. I am very angry, beyond words. Subaru is coating people alot of money. I would never tell anyone took get a Subaru.
2019 Subaru Outback passenger side cam carrier started to seep at 42k miles. 63K continues to seep and Subaru suggested monitoring oil levels. Estimated cost to fix $6k. If leak gets worse and/or proper monitoring of oil in the engine is not done could lead to engine failure and costly repairs.
2019 SUBARU OUTBACK. CONSUMER WRITES IN REGARD TO UNINTENDED ACCELERATION. THE CONSUMER FEELS SHE SHOULD NOT HAVE TO BEAR THE COST OF THE REPAIRS AND FEELS UNSAFE IN THE VEHICLE.
The vehicle has developed an exhaust leak which allows exhaust to enter the cabin of the vehicle especially at lower speeds and when stopped. There is a crack which develops in the exhaust manifold which causes this issue. This is a known problem and there have been recalls in the past with this exact same issue for Subarus with the same engines. This poses a safety issue given the exposure to Carbon Monoxide.
The contact owns a 2019 Subaru Outback. The contact stated the low lever oil warning light illuminated on the instrument panel. The vehicle was taken to an independent mechanic, and he stated that the oil was low in the engine and more oil was added to the engine. The contact stated that in less than 5,000 miles the vehicle had burned all the oil in the engine. The vehicle was taken to the dealer but was not able to get a diagnosis on the vehicle. The manufacturer was not contacted. The failure mileage was 30,578.
Battery died following limited use.
Frequently while stopped at traffic light, fast food pickup line, or intersection engine begins rapid unintended acceleration with RPM racing as high as 8K. The brake pedal is firmly pressed yet the car attempts to lunge forward. The only way to stop the acceleration and return the car to normal idle is to place the car in park while the engine is racing. Placing the car in neutral does not stop the acceleration. I stop well behind vehicles ahead of me, but on one occasion nearly rear-ended a Porche! Dealer cannot reproduce problem since it is only intermittent. I keep a log of incidents with time, driving circumstances, and other data. No warning lights appear and no accidents have yet happened. I have reported problem several times to dealer with no resolution.
RANDOM LACK OF ACCELERATION AND ENGINE STUMBLE; FAILED TO ACCELERATE WHEN PULLING OUT INTO TRAFFIC FROM SIDE STREET NEARLY BEING HIT BY ON-COMING CAR. SEEMS TO HAVE BECOME MORE FREQUENT AFTER ENGINE FUEL PUMP WAS CHANGED DUE TO RECALL.
CAR SOMETIMES ACCELERATES ON ITS OWN. I HAVE TO USE PEDAL SHIFTERS TO REDUCE THE SPEED. ALSO NOTICED THAT IT TAKES LONGER TO BRAKE SOMETIMES.
