Subaru Forester fuel gauge problems

Filed Mar 25, 2026 · Engine · VA

This has now happened twice to my daughter, both times on the highway. One time the car shut down completely and the 2nd time the car just started slowing while pressing the gas and coasted to a stop. Luckily she was able to avoid other cars and get to the shoulder. The car restarted both times...1st time after about an hour wait and 2nd time within minutes. Both incidents happened when the gas gauge was at 2 bars. I am terrified of this thing right now. No warning signs at all prior to the incident. I took it to the dealer after the first incident but they could not figure out what the problem was as they were not able to recreate the issue. This is an extremely unsafe issue and I am not sure what I should do next.

While there were no reported incidents, it appears there may be manufacturing defects with this vehicle. The rear seat safety belts are reportedly quite difficult to fasten, as the receptacle is positioned deeply within the seats, sometimes making it impossible to secure the belt. This then triggers an alarm, which can be quite bothersome for the driver. Furthermore, there seems to be an issue with the fuel gauge, as it may display an inaccurate reading. For instance, upon filling the tank, the meter might show 470 ml, but while still at the gas station, it could indicate 330 ml. Additionally, the reading can fluctuate after a trip. Finally, the air conditioning vent on the driver's side does not seem to be functioning correctly. In one instance, despite a minor road hazard that was not immediately noticed, the left rear tire was completely damaged. Despite multiple attempts to address these issues at the showroom and contacting Subaru headquarters, the problems persist. Note the purchase of vehicle forced upon me ,in addition Hallmark Subaru refuse to address the issues with vehicle. I have reported the matter to AL state Attorney general. Still no response made by state AG. Thank you.

My Subaru smelled like gas and caught on fire while I was driving to work less than 72 hours after it left the service department at the local Subaru dealership. Earlier that week I dropped the car off for service due to a check engine light and multiple other warning lights on the dashboard. The check engine light was determined to be due to a faulty thermo control valve (a known issue on several models of 2019-2021 Subarus). During that service appointment, the thermo control valve was replaced under warranty, the 60000 mile service, state inspection, and an oil change/tire rotation were completed. The morning of the incident, the car smelled like gas, but there were no warning lights on the dashboard and the temperature and gas gauges were all in range. While looking for a safe place to pull over on the side of the road, the gas smell worsened, I heard a pop, the check engine light and every single other light on the dashboard lit up, it smelled like burning jet fuel, and the front of the car was smoking and there were flames, and all mechanical and electrical control of the vehicle was compromised. The car coasted to the side of the right lane. I was unable to operate the gear shift to put the car in park. I opened the driver’s side door, removed my seatbelt, grabbed my backpack, lunch bag, and phone, and exited the vehicle while it was still rolling. I ran around the back of the car to get onto the side walk. Flaming, melting pieces of plastic were coming off the bottom of the car. Flames and smoke were visible on the front hood of the car. I called 911 while the car continued to roll across several lanes onto the other side of the road. The burning car rolled and hit a guardrail on the opposite side of the road and continued to burn until the local Fire Department arrived on scene. Local police and the fire inspector wrote reports. My insurance declared the car a total loss. I have informed the local dealership and worked to get them access to the vehicle.

This is the fourth time we have had the same problem. We were on a long drive (more than 1 hour on the road) on the freeway going 65-70mph. The fuel gauge showed 2 or 3 bars left and the estimated mileage left was 40-70 miles left when the car lost forward power, the lights still worked and electrical systems were functional but it was as though there was not gas left. We had to call a tow truck to bring us gas. As soon as they put a couple gallons in the tank the car started and continued without issue to the nearest gas station. This was extremely dangerous as we had our children in the car and had a loss of power on the freeway and had to sit on the side of the freeway in a dangerous area waiting for gas to be delivered. We took it to our mechanic who could not detect any problems with the sensors, or other systems, there were no codes generated and no warning before it lost power, the low fuel light hadn't even gone on.

Much like the 2018 Outback issue I had, my 2020 Forester is having the same issue with fuel indication inaccuracy and mpg increasing when fuel level gets under a quarter of a tank. My local Suburu dealership said this is not an issue for this model. I have reported this to Suburu as well. Previously, Subaru found that the software that controls the fuel system can cause the fuel gauge to show that there is still fuel left in the tank when there isn’t. More specifically, the low fuel warning light may not actually come on, and the miles to empty display could be inaccurate. The software is causing additional miles to be showing when they are not available. I don't know if this is a similar issue or not, but no one has fixed it. With any vehicle, you need to be able to rely on the fuel gauge. Knowing how full (or empty!) your gas tank is extremely important when driving, particularly if you are driving a long distance. If you do run out of gas, the engine can stall; fortunately, the vehicle can be driven to the side of the road if it stalls when you are in motion. As the issue involves a software bug, it is easily fixed by the dealership.

Fuel gauge system became inaccurate in February 2022, showing 100 extra miles available upon filling tank, 450 instead of 350, also gallons left on fuel gauge was inaccurate, off by 4 gallons. Went to Subaru dealership/Service Dept. & was told that I would have to replace gauges & fuel tank, due to warranty past 3 years. I decided to not replace, just keep track. They said they'd never heard of this problem before. It lasted approximately 3 months & went back to normal, then beeped & became inaccurate again while I was starting engine 4 months later, & re-adjusted back to normal after a couple weeks.

This is the latest time in a series of incidents where the SUV would not start due to a problem with the main battery. New batteries drain very quickly after a series of electrical problems. So far, we have noticed keyless entry FOB says battery in the FOB is low and stops connecting (but then connects if we remove the key from it without us holding it to the button that turns the car on and off), we replace this battery but continue to have the same issues, front passenger side window is not able to be rolled down or up from driver side, as the battery continues to drain, gas gauges stop correctly registering amount of gas in the car, different warning lights light up on control panel without any sense of rhyme or reason, and overhead lighting gets dim. For a few weeks, the SUV blames the problems on the battery in the key FOB being low, even though it was replaced on December 15, 2021. When replacing the FOB battery did not work, we learned it was the actual main SUV battery that had been drained. It is now March 19, 2022, and we are having the same issues despite having only a moderate amount of miles put on the SUV and only 3 months of time passing since we purchased and installed a brand new car battery. We will have to spend money on batteries again.

Fuel gauge sending unit not functioning causing car to over report remaining gas mileage. Car runs out of gas though gas gauge still reports roughly 20% tank capacity remaining and ~60 miles or range left. This has happened to me multiple times,racing me stranded on highways at least 6 times.

On two separate occasions, our car stalled while I was driving on a major highway at 60 - 70 MPH. (2016 subaru forester) the first incident was on friday, june 21, 2019 on pa route 283. The second incident occurred on wednesday, march 17th, 2021. In both cases the car engine died without warning at speeds of between 60 - 70 MPH. Needless to say, this was a life threatening situation. My fuel gauge indicated that I needed gas in the first incident but I estimated that the car had a little more than a gallon remaining. In the second incident, the car had about a quarter of a tank of gas. I contacted sabaru after the first incident but I'm not aware of any action that was taken. I also contacted them after the second incident but have not yet heard back yet. Bsed on my research, other owners of subaru foresters have had a similar experience. I'm surprised quite frankly that no deaths have been reported.

After 4hrs of driving with 2 pit stops in between, I was in 3 lane traffic and down to 1 bar on fuel gauge stating I had 50mi left of driving remaining in tank.. Low fuel light hadn't even turned on yet, only to find that the car had lost power and reduced speed and wouldn't accelerate when I used has pedal. However the interior lights and power windows still worked. I was able to pull off to the side of road and shut the car off. I looked under the hood and found nothing to be out of sorts. No dash lights went off either such as battery or check engine. I started the car back up in 5mins and fueled my car up. Also, during the trip my fuel mileage was consistently going down which the lowest reading days 17mpg when normally 30mpg. This happened the day after taking my vehicle in for new tires at a corporate tire company. 2 weeks later car having troubles starting. Battery and alternator checked out good, so suspected fuel pump. Car dealership states fuel filter inside the pump and even if there was a way to test the pressure it may not be accurate because it could be intermittent failure and doesn't recommend me replacing it. They wanted me to wait until it happens again before looking into it any further. They checked for dtc codes and found none. Also suggested I just upgrade to a newer vehicle and I stated that at 138,000 the car should still be repairable and driveability otherwise what's the point of purchasing to own the vehicle. Obviously the situation was dangerous and could lead to a slew of problems such as standing, accident or even death.
