2018 Subaru Forester: jerking or lurching

Filed Nov 7, 2026 · WI

Approximately a half dozen times since I bought my 2018 Subaru Forester Premium new in December of 2017 it has exhibited unintended acceleration, usually after I start it or travelling slowly, as when doing parking maneuvers. When this happens the car will suddenly lurch forward and the engine will roar, even when my right foot is firmly on the brake and no foot on the gas pedal (I use my right foot only on the pedals). The only way I've found to stop this problem is to turn the car off. Upon restarting the car, it drives normally again until this problem reoccurs, which may be weeks or months later. I've examined the possible reasons that this is happening and have eliminated the possibility of the car mat or pressing the wrong pedal or both pedals at the same time. I've tried to press both pedals at the same time on purpose with the car off to check if this is possible, and am unable to press both pedals without my foot slipping between the pedals. I've also experienced the power steering warning light illuminate a few times upon starting the car, upon which the car has no power steering. Turning the car off and then back on again has solved that problem.

On October 3, 2023, I purchased a used 2018 Subaru Forester (VIN: [XXX] ) from Hengxin Auto Group, 210 39th St, Brooklyn, NY 11232, for about $19,500 including tax and fees. The dealer stated the mileage was 65,800 and printed that number on the contract. However, both the official NY DMV Title Record and the Carfax report showed 86,588 miles at the time of sale. This clear discrepancy proves the dealership intentionally rolled back or misrepresented the odometer reading. Later, the title was branded “mileage unknown.” After purchase, many severe issues appeared: chassis instability, transmission jerking, loud engine noise, high oil consumption, A/C malfunction, battery failure (replaced at my own cost), and worn tires that left me stranded. The dealer had advertised the vehicle as “excellent condition, only minor scratches,” which was completely false. I repeatedly contacted the dealer, but they only made partial chassis repairs and ignored all other problems. I paid significant repair expenses and eventually had to trade in the car on April 29, 2024, at Romano Toyota for $12,530.24, while still owing $13,705.58, resulting in a direct loss of about $9,283.78, not including additional repair and transportation costs. On October 2, 2025, I sent a formal demand letter to Hengxin Auto Group requesting compensation for odometer fraud and vehicle misrepresentation. The letter was received on October 9, but no response or resolution has been offered. The dealer’s conduct involves clear odometer fraud and nondisclosure of safety-related defects. I respectfully request the federal safety agency to investigate this case and take appropriate action to prevent similar consumer deception and safety risks.

2018 Subaru Forester stalling in intersection Prior there was an occasional delay in starting. After light changed I was starting to move down a hill toward expressway entrance at about 25 mph. I was in the middle lane and all cars were coming behind me at 50mph. I just entered the intersection when my car just stopped. It would not move. I was trying the gas pedal but car did not move. Suddenly it began jerky movements, moved a few feet, sputtering and stopped again. Now I’m in the middle of the intersection. I looked in my rear view mirror and saw cars speeding down hill, honking as they went around me. The car repeated jerky movements, moved a few feet and stopped again. I was still in the intersection and light was about to change. It finally repeated the jerky movements, etc until it stopped a third time. Fortunately I was out of the intersection and along the roadside. I reflected on what had just happened a few minutes. Then I made my way back home 35 minutes slowly driving on back roads allowing cars to pass just in case it would happen again. Dealer told me there was extended warranty on fuel pump but he could not repair as he could not duplicate stalling. How many times do I have to stall in City trafficI or expressway before my fuel pump will be replaced? I had a kidney transplant that saved my life. I will not let a safety recalled fuel pump put me in danger again.

The initial incident happened when I was accelerating uphill. When I pressed the gas pedal to accelerate, the car began jerking and sputtering. I released the gas pedal and let the car coast, as I was heading toward a stop sign. After I stopped and then accelerated the second time, the engine seemed to smooth out. Nothing further happened until about 1 week later. The second incident, I was 35 minutes into an hour-long drive. I was going around 45-55mph when the same issue happened suddenly: I pressed the gas pedal and the car started shaking and sputtering. If I released the gas pedal, the car was fine. All check engine lights came on and were flashing. I lowered my speed into the 30s, and the issue continued to happen, regardless of what speed I was driving at. If I was accelerating, the car was shaking a lot. At stop signs, the lights would turn off, but pop on as soon as I began driving again. I was able to make it to my destination and when I parked the car, it was shaking a lot while idling. It felt like the engine was about to die or shut off. It was late so I turned the vehicle off and left it parked for the night. The next morning, when I started the car, it was continuing to shake/sputter during idle and I drove it briefly to see how it ran. It continued to shake when pressing the gas pedal, however, the check engine lights were not on. Since I had to drive back home, I decided to take it slow and began the two-hour drive back. The engine again seemed like it wanted to die as I let the car warm up, but it did not shut off. Initially when driving, the car continued to have the same problem - shaking whenever I pressed the gas pedal, no matter the speed. The check engine panel lights did not come on, however, and after driving for about 20 minutes, the issue cleared up. I've only driven it as needed since then and it is currently running ok, but, given the numerous fuel pump recalls I'm concerned there is a defect with this model.

The CVT transmission is begining to fail, the car has come near stalling several times and has a very rough/lurching shift while accelerating onto highways and merging. Subaru dealership says it does not qualify for a warranty replacement even though Subaru extended the warranty specifically for this problem.

When applying gentle gas pressure at low speed car does not respond for 2-4 seconds, then lurches strongly forward as tho full throttle has been applied. Happens at random times. Dealer said nothing wrong when first happened 2 years ago. Was rare until today when it happened 6 times within 50 miles of city driving. Will see dealer tomorrow. No warnings of any kind. Grave safety hazard as could be hit by traffic when trying to enter street or get out of somebodies way when car does't respond.

I have AC problems, refrigerant leak, actuator problems, bad compressor. I have serious CVT surging and suspension problems that make vehicle unsafe to drive. The car literally begins to hop like you are stomping the gas and breaks back and forth and can easily make you lose control. It sometimes does nothing when pressing accelerator for way too long making it dangerous pulling into traffic. Windows roll down without pressing button and won't roll back up unless you roll them all the way down first and usually it just rolls right back down again. Aweful trying to drive while fighting with windows that won't stay up. Suspension is so destroyed from the surging and hopping that it cannot be aligned. The vehicle destroys tires rapidly and unevenly. Gas mpg is terrible, especially if you run AC. Steering assist is dangerous and will sometimes jerk wheel away for no reason causing you to scrape curbs and nearly hit a pole once.. Breaking assist is also dangerous as it will slam breaks for no reason. Lane departure beeps a lot for no reason. Wipers are garbage. Windshield glass is too soft and all dust scratches it making visibility poor the trunk often will not open no matter if you push button on key, inside car or on trunk. The door seals fell off, cheap clips fall off that are supposed to hold important things in place, glove box shock broke. I'm sure there are other issues too. Suspension is a big issue however, completely shot from surging. Far too expensive to get whole new suspension. Dealership ignored all complaints and purged all records of visits so I couldn't file lemon law. Subaru is very dishonest. So many things need recall that it is a lemon pure and simple.

Upon entering a parking space, with break peddle engaged, the vehicle lunged forward at extreme speed hitting a protective barrier. After a rest period, the vehicle was put in reverse and with break peddle engaged lurched backward at the same excessive speed hitting another object. After a long period with engine turned off, the operator was able to drive the car slowly. The vehicle is to be examined to determine the problem.

Vehicles driver seat rail has become loose causing seat to slightly move when laying back.. Could be hazardous while driving.. At initial take off, acceleration jerks, acceleration is not smooth, after slightly pressing on the acceleration pedal, I have to sometimes brake because acceleration is jerky and rough. I just purchased this pre-owned 2018 subaru forester with 14k miles and it is already blowing smoke at start up.

A few incidents have happened since the latter half of 2020: while at a stop light that turned green, my car stopped moving for a few seconds despite pressing on the gas pedal and the RPM went up to 6/ loudly revved. I was almost rear ended at this light.the car has also had this lack of movement issue on the freeway while in traffic. My car jerks several times on slight inclines especially after surpassing 40 MPH. Often times, I cannot accelerate past 40 MPH regardless if the drive is on a flat surface or an incline. The RPM will increase, but the gear feels like it will get stuck and the car makes a loud noise. This is the most noticeable going from 40 MPH to 50-55 MPH. These incidents are on city streets. However, power often gets lost going on to freeways for the same reason. I cannot surpass 40 MPH when entering a freeway and was almost sideswiped on the driver's side by an impatient person entering too early where the on-ramp merges with the freeway because of this. While on a freeway, the car will continue to accelerate despite attempting to slow it down by pressing on the brake or coming to a complete stop. This has also happened on city streets and poses a safety issue. The acceleration when this happens is much faster than when I try to manually accelerate the car myself in other contexts, like mentioned above. I believe it is the CVT as this seems to be a common problem with cars of my make, model, and year.

First, driving on the highway the air conditioner stopped working. Second, the very next day, the vehicle began to make noises (squealing) when driving it anywhere. Streets, turns, hills etc. Then it began race and it felt as if the back tires were racing to catch up to the front tires. There was lurching forward. Shuddering. No dashboard warning lights came on. I called the dealership, then took it to the dealership. It was scary to drive it there. I felt like the transmission was going up. Third, the tailgate, ( in or out) release buttons were not working consistently (repeat complaint). I left the vehicle at the dealership and telephoned subaru of america. This 2018; I had owned for exactly two months. I had only driven the car approx 1200 miles total. Mileage 47,000. The dealer has repaired the AC and CVT transmission. The AC is a known problem and it was the condenser that was leaking and needed replaced. The CVT is also a known problem. The service tech test drove the vehicle and able to duplicate concern. He found the RPM increased and the squealing could be heard. Vehicle would shudder. When he removed the pan he found metal in the oil. Confirming the CVT (transmission) needed replaced. Repairs were made under the extended warranty. Given the information found on the web regarding these problems it was important to report that these problems continue. Safety is concern.
