2014 Subaru Forester fuel system problems

Filed Dec 7, 2025 · Electrical, Engine · GA

On 5/15/2024 and 5/21/2024 I had sudden uninteded acceleration. I had a auto shop try to solve the problem by replacing the air fuel ratio sensor and the mass air flow sensor. This seem to fix the issue until 11/27/2025 & 12/7/2025 when the sudden uninteded acceleration returned.

I was driving my 2014 Subaru Forester (about 148,000 miles) behind a minivan at a safe distance and speed. Without warning, my vehicle accelerated uncontrollably. Despite applying the brakes, shifting into low gear, and using the emergency brake, I was unable to slow it down. After impact, the car then hit a telephone pole, spun me around and rolled the car over. There is major damage to the car and we looked at it at the tow yard but the salvage adjuster is moving it shortly.

This morning 2/20/2024 I was driving up a main commercial street in traffic, going about 10 -15 mph. I did not have my foot in the accelerator or brake as I was on a very slight incline. Suddenly, the car accelerated, made a roaring sound as if the accelerator had been stepped on strongly and started to jerk forward. I jammed on the brake and stopped the car. I did not hit the car in front of me. This happened once before, several years ago, but not to the extent of this time. The car has 45, 400 miles on it and was just serviced at the Subaru dealer 2 weeks ago. There were no problems noted at that time. There were no warning lights, messages, or other symptoms of the problem prior to this incident. It was probably the accelerator and fuel systems that failed. I have made an appointment with the Subaru dealer, but can't get in for a week. It was a dangerous and frightening incident. Fortunately, I was quick to respond and had a safe distance from the car in front of me. It could have been a very serious event had I not been quick to respond and had read in the past about this problem with the Subaru Forester. I tend to be a very alert, focused, and aware driver.

This is one of the emails I sent to Subaru. I had just paid 425 to replace a tail light when the seal failed, the same time the wiper motor went bad 600+ to fix that. This car was in such bad shape they did not even recommend repairing. I had to buy a used car which was a financial hardship. I believe Subaru should reimburse me the cost of the transmission and tail light assembly Gentlemen, I'm writing to you to express my EXTREME regret in buying a Subaru. If I went into all the repair details, it would take forever. My new case number is 2303131700678. I m requesting that this repair be covered and paid for completely by Subaru, as well as the money I paid towards the new transmission be refunded to me. Once you review all the repair records, you will understand my frustration. This whole car is an example of poor engineering and quality control. I held up my end of the deal, I paid off the loan, I maintained the car thru scheduled maintenance at the dealership. Subaru has failed me. Have your team pull all my repair records and read them thoroughly. Note the bad bushings, note the failed back up camera, note how the entire under the hood has failed at only at 120,000 miles. Where is my 200,000 miles that you claim the car should last? Subaru sold a defective car, Subaru knows darn well that this model has transmission and oil issues. I don't care that my systems failed after the 100,000 extended warranty. If you did your job right, you would not have to have extended it. I look forward to my transmission reimbursement and the complete repairs the car requires AT NO COST TO ME. It is your turn to uphold your part of the bargain.

My 2014 subaru forester's engine at times acts as if it is going to stall. It acts as though it is getting no fuel. I have had the fuel filter/fuel pump assembly replaced and it seemed to run ok for a short time. The stalling action does not always happen. Sometimes it runs smoothly. Then it starts the sputtering/stall action again.the mechanic who replaced them in an effort to correct the problem is not able to tell me what else could be causing it. My vehicle gets 93 octane gas and only has 32,000 miles on it. Please help.

Tl* the contact owns a 2014 subaru forester. The contact stated that the vehicle consumed excessive amounts of oil with the check oil warning light illuminated on the instrument panel while traveling at various speeds. The contact took the vehicle back to the independent mechanic where she purchased the vehicle and had two o-rings and crank seal replaced under warranty. Despite the repairs, the failure persisted and the check oil light would continue to illuminate after every 1,500 miles. The contact took the vehicle to center subaru (45 winsted rd, torrington, ct 06790) to have the vehicle serviced under the federal safety agency recall number: 19v149000 (exterior lighting). The contact was informed that the dealer could not assist with the excessive oil failure due to the vehicle no longer being under warranty and no other recalls being placed on the vehicle. The manufacturer had been notified and gave her the same information as the dealer. The vehicle had yet to be repaired. The failure mileage was 121,286.

While driving on the freeway under excellent conditions, the engine 'revved' and then stalled. I was able to pull off onto the shoulder and put the car in "park" and turn off the engine. Before I did so, the insrument panel indicators were (almost?) all lit. I tried to restart = unsuccessful. After waiting about 5 minutes, I tried again and was able to proceed normally. This is the second time this has occured; previous episode about three months ago (unreported) under similar conditions. The only "common" element I can surmise is that the gas level was < 1/4 tank in both instances. I was not concerned about the gas as the gauge and "miles to empty" were more than sufficient to get me home. I did refuel within ten miles of the temporary breakdown and was able to drive without further incident.

2014 subaru forester stopped running while driving down the freeway at 70 miles an hour. Engine just quite running. Lost power. Had to pull over in median. Very scary. This is second time this has happened. Did not throw a code message. Dealership can not detect problem. First time was 4 years ago when driving at 35 MPH on city street coming into town. Did not throw error message at that time was told to drive it until it did it again.

At/about 1230 central time on 31 oct 2019, my wife [xxx] experienced an uncommanded acceleration event in our 2014 subaru forester and narrowly escaped being killed. Context: my wife was taking the car through an automated carwash at the caseys gas station at 9911 s. 71st st in papillion ne. When she reached the end of the conveyor belt and when signalled by the attendant to move forward, she stepped on the brake and attempted to move the automatic transmission from n (neutral) to d (drive). She encountered resistance moving the gear lever but was able to move it to d. Upon doing so, the car abruptly accelerated and lurched forward despite her foot remaining on the brake. The car rapidly accelerated and tore through the closed garage door at the end of the carwash and continued outside, across an access road and up a small hill, before losing power and rolling backwards down the hill to stop in the access road. No other vehicles or persons were involved or injured. My wife was uninjured other than being sprayed by glass fragments from the windshield as it was punctured by the garage door as the car tore through it. Our insurance company (usaa) declared the car a total loss. Neither my wife nor I had ever experienced anything like this incident before; we both have excellent driving records. Weather at the time of this incident was clear, dry and sunny. The car to the best of our knowledge was in excellent mechanical condition. The papillion ne police dept responded and filed a report, and we filed a drivers motor vehicle accident report. Both are on file with the papillion ne police dept. There were also several witnesses to this incident per the police report. *ln*jb information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).
