Engine And Engine Cooling Problems of Subaru Forester - part 2

I was stopped at a red light and the engine stalled. It read "for safety, auto restart disabled". All warning lights on the dashboard lit up. I had to put the car in park and restart it in order to drive. I was honked at and put in a dangerous position. This has happened at least twice now.

I just found out that there was a problem with oil consumption in a 2014 Subaru Forester. I purchase it two years ago. Is there anything they can do to fix it.

Yesterday 6/19/25 I was driving out the driveway when the vehicle accelerated on its own, and not slowly, but like it had been punched. I was actually coasting at the time since I didn't want to stir up dust. My foot was not on the gas pedal. And it was not the floor mat. It happened on its own, the first time in 87,000 miles. It probably cannot easily be replicated as it was completely random, although now that it's happened once, it very well could happen again if there's a faulty or aging part or sensor. Neither the local dealer nor Subaru has acknowledged the problem (I called both today) but it's a serious safety issue. No check engine light or other means of warning. It just happened out of nowhere. Glad I was in the driveway and not in town waiting while a pedestrian was crossing the street.

While at a stop as the engine turns off and awaits decompression of brake to turn on again vehicle moves forward bit, then the engine shuts down while in drive (stalls) had a vehicle hit me in rear but luckily I had my trailer hitch on because it saved me from body damage . I had to place in park and restart this has happened several times before and I’m kinda nervous and makes my wife nervous when stopping at lights or stop signs it might turn off in the middle of the intersection. When this occurrence happens all dash lights pop up … I checked engine with code reader after the incidents but it doesn’t give out any info on what could possibly be happening. I had the dealership change the thermo control module in 2025 but these occurrences has happened before and after the tcm replacement. Having the dealership check is like wasting my time and money because they aren’t able to pinpoint the cause without a code . There has to be a problem somewhere in the system it’s just that the dealership in hawaii has no clue . .

During severe stop/go, thick, holiday traffic on I-495 (DC beltway), during daylight hours, once again (this has happened several times before), the auto engine shutoff feature catastrophically malfunctioned, turning the car off, and simultaneously, activated the entirety of the dashboard to flash on/off, causing nearly every indicator light to come on, and then had difficulty restarting. This has been brought to Subaru's attention multiple times and they essentially have washed their hands of it and stating since they can't duplicate it, it essentially must not be occurring and they cannot repair it.

My Subaru suddenly had numerous warning lights go on. Took it to the dealer and they said it was due to a recalled part: thermo control valve. They replaced it for free but said my head gaskets needed to be replaced after checking my oil for $4000 plus. I believe the recalled part caused the head gasket issue and shouldn’t have to pay also the mileage is only 66k.

2021 Subaru Forester limited- stop start when stopping at a red light. Sometimes the engine does not restart when releasing the brake pedal. Message on dash put car in park and press start. Occurred. April 24 2025 and may 5 2025.

Subaru forrester was misfiring and sputtering as if it was going to stop running. The car was shaking. Had car towed to Subaru dealer for service. At first we thought spark plugs and ignition coils but this did not fix the issue. Service determined a spring valve was broken which caused the issues. I have escalated the issue with Subaru corporate, waiting for their response. Other Subaru models have had this issue with the spring valves.

Was stopped at traffic light. Start stop system was engaged. Engine turned off as normal. When I took my foot off the brake the engine did not engage and the eyesight warning light came on that the eyesight system was not functioning. Put the car in park and engaged the ignition button and the engine started. Turned off the start stop system and the car functioned normally after that. Have read postings on Subaru forum that this has happened to others.

Auto start/stop shut off engine at drive thru line. Locked up brakes and could not get it to unlock and restart car. It has happened on a number of occasions. After multiple attempts trying and letting it sit for a couple of hours, somehow got it to unlock and start. Thank goodness we haven’t gotten into an accident.

Currently suspected that the vehicle battery was installed incorrectly during assembly. Engine fire started at the battery wiring and vehicle was a total liss.

Vehicle had just received an oil change at the dealership and the car caught fire. Oil leaked onto the catalytic converter and ignited. Car was a total loss. After my own review, there are several instances of this happening and many customers have experienced similar fires. The oil filter is inverted which makes leaks more susceptible.

At signal/stop sign or in stop and go traffic, engine shuts down. Car is in park. Engine (or car) makes beeping noise when this happens. Eyesight disabled shows on the screen (however this has nothing to do with that) there's existing lawsuit for cars until 2020. This problem exists for some 2021 model as well. Similar problem: [xxx] this is a recurring intermittent issue. Can't reproduce consistently information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

When I first noticed that my car wasn’t heating properly, it was in may 20 24 when I purchased the car and carvana dropped it off to my place of residency. When I notified someone of this issue, they told me it probably just needed coolant. I did as instructed and noticed that I was adding in coolant frequently. On February 19, 2025 I returned home one evening and noticed that smoke coming from my car and coolant was leaking from underneath. I called roadside assistance in order to get my car towed and into service at the Subaru dealership. After inspection, the mechanic noticed that there was oil inside the coolant suggesting that there may be an issue with the head gaskets then warned me not to drive my car because there could be further issue with the engine as a result of the head gasket being blown.

Periodically, the vehicle stalls at stop lights, stop signs, and in other situations when coming to a complete stop. Once the vehicle comes to a complete stop and turns off due to the auto-stop/start function, it stalls immediately after the car re-starts and you press the gas pedal. This leaves the vehicle stalled in intersections and in potentially dangerous conditions. You must engage park and restart the vehicle while stopped in the middle of traffic, which poses a significant safety risk. I believe this issue is related to the auto-stop/start functionality. The vehicle has been inspected by a Subaru dealer several times, but they claim they cannot reproduce the problem and there are no diagnostic codes or warning lights. No other mechanic has inspected the vehicle.

My Forester just totally shuts down sometimes from the auto start feature in traffic or intersections . Errors come up . The wheel locks and I must put the car in park , turn it off and turn it back on. Very scary and very dangerous.

We were driving at 70mph on the freeway, left lane, and suddenly the car lost power as if the fuel pump went out. We had to suddenly get over to the shoulder of the freeway, almost got hit, then limped along the shoulder until we called a tow truck which towed us 40 miles to Subaru dealer. The dealer looked at the car and "couldn't find anything. " now we are afraid to drive the car.

For the second time we were on the freeway at a hight speed and the car suddenly lost power, all the warning lights came on, and we had to get off the freeway (dangerously). We almost got hit, and other cars had to brake radically. We took it in to Subaru and they said the catalytic converter was bad. They replaced the catalytic converter, and when they took it for a test ride, they found that the second catalytic converter was bad. Apparently they have two. The car must have suddenly lost power for them, too. We have 85k miles on the car, and the Subaru warranty for the catalytic converter is 80k. We're into it for thousands of dollars, but the most important reason I'm making this report is that someone is going to get killed on the freeway because of these failing catalytic converters, and it might not be people in the Subarus. The car just died at that speed in the left lane, and it was a miracle no one was killed. (I'm not sure if I have my date quite right. My calendar is not at hand). Note: Subaru is having a hard time getting the part, a delay, they say, of many days, so that makes me think that this is happening widely, and that these catalytic converters are getting replaced at an unanticipated rate.

At 40936 the valve body needed to be replaced. With such low milage vehicle is having problems.

My car has required multiple jumps and batteries, since I bought it new. I have records of the services for jumps, and new batteries. The car continues to have a parasitic battery drain, that has caused me to be stranded multiple times. The car is currently at the dealership, and they want to do a dcm test to see if this is cause. I was not informed of battery class action lawsuit, and extension of dcm warranty by Subaru. The dealership staff never discussed this with me as a possible cause, and that I may be eligible for warranty.

Ticking noise on cold start up as well as reduced acceleration speed and torque. Diagnostics point me to believe the avcs solenoids are beginning to fail prematurely. This has not been confirmed by a dealership and the issue is reproduced during any driving. There are no cel lights active or codes stored. The vehicle currently has 74,*** miles. The issue started within the last 6 months. This is a safety concern when attempting to get up to highway and freeway onramps or getting up to merging or passing speeds.

12/14/24-I was stopped at a red light at a very busy intersection. The engine was in stop mode by the start/stop feature. When the light turned green, the car failed to start. The entire car shut down, with alarms sounding and dash lights flashing. The entire system had to reboot before I could restart the car. It was a freighting experience. Fortunately, I wasn't killed by traffic zooming by or by some person with road rage. 12/16/24-issue evaluated by local Subaru dealer. Their evaluation was that when the auto start feature was activated, my car battery was too low to work. There was zero warning about a low battery before this failure in traffic. I had to buy a new battery. The auto start/stop feature is not an enhancement, but a safety hazard. Owners should be able to permanently disable this unnecessary drain on batteries and starters. I did a search, and there are plenty of others that experienced similar issues with their Subarus.

When I break and stop the car power is reduced, at times it stalls out and be hard to start again when starting back up in traffic. This is also starting to happen in my other forrester of the same year.

Subaru Forester engine stalls at an intersection due to auto start stop feature of Subaru to save fuel, except that this is the second time when engine is idling it lowers the revs and then it stalls when trying to auto start engine; first time the dealer said is battery issue, I replaced the battery at my cost, and this is the second time. It is dangerous because there are oncoming traffic and I have only a split second to turn on my flashing lights. This is a brand new battery install on 9/2024.

"check engine" light along with "eye sight" appeared suddenly on Nov. 22, 2024. All safety systems along with cruise control became inoperable. Took car to Subaru dealer and it was confirmed to be the catalytic converter. My VIN is covered under extended warranty, but I was never notified of this. Plus, now repairs are of an emergency nature. Also, I do a lot of driving including on the NJ turnpike, I-95, etc. , and while I am awaiting car to be repaired, I have no safety features to rely on--which was one of the reasons I bought a Subaru. They will not pay for a courtesy car loan. Another issue is the thermo control valve. I was notified that I have an extended warranty for this, but part has to fail before Subaru will make repairs. Once again this becomes an emergency repair situation instead of a proactive one.

While driving my 2016 Subaru Forester about 70mph on 880fwy in san jose, CA, the engine suddenly stalled and I was stranded on the freeway. The fuel tank was about 3/4 full and no warning light flashed in the dashboard prior to the incident. I tried to move my vehicle to the right lane but was unable because of the vehicle's loss of power. I almost collided by a speeding truck behind me. I shut off the engine, was unable to restart. After 3 minutes later, I was able to restart and everything worked again. I suspected the cause was due to a bad fuel pump, took the vehicle to my local Subaru dealer for inspection. The technician could not find anything malfunction or repeat my problem. I just learned there was a recent lawsuit settlement of bad fuel pumps on 2017-2020 Subaru Foresters that could cause engines to stall. It sounded similar to the problem that I had just experienced, except my Forester is a 2016 model not covered by the settlement. I believe the 2016 Forester fuel pump was manufactured by the same company as in the 2017-2020 models. It probably has the same defects.

I have a single-owner 2011 automatic-transmission Subaru Forester [145k miles]. In a parking lot, I started the car as usual and shifted into reverse. I immediately noticed another car was approaching behind me and reflexively pushed on the brake to give the oncoming vehicle the right of way. As I pushed on the brake, the car suddenly and without warning surged backwards as the engine revved and "stuck" at a high rpm level. Surprised by the sudden loss of control and to stop the lunge backwards, I immediately released the brake pedal and shifted into neutral. I believe this reflexive action was solely attributable to my long history driving manual transmissions which "teaches" your brain that as an alternative to using the brake you can clutch [or if necessary "pop"] to neutral to disengage the engine from the wheels to control the vehicle. People without manual transmission experience would probably keep pressing the brake as their only option to regain control. The car stopped but the engine continued to rev at high rpms for a few moments then returned to normal rpms. No damages. This has never happened before and I was unable to duplicate the sequence of events which I tried to do immediately after the incident. I thought the gas pedal might be mechanically compromised . . . For example by the floor mat . . . But found no evidence of that. The incident remains a mystery mechanically, so all I can surmise is some electrical issue.

The contact owns a 2017 Subaru Forester. The contact stated while driving at an undisclosed speed, the check engine warning light illuminated, and several safety features failed to function as intended. In addition, the contact stated that the check engine warning light had been illuminated intermittently for over a month prior to a diagnostic test. The vehicle was taken to the dealer where dtc code: p0420 was retrieved, and the vehicle was diagnosed with catalytic converter failure. The contact was informed that the catalytic converter needed to be replaced. The vehicle was scheduled to be repaired. The contact researched warranty extension: 09-84-22; however, the contact was informed that the repair was not covered under any warranty programs. In addition, the contact stated that the case manager provided false information and stated that the warranty extension document did not exist. The manufacturer was made aware of the failure and a case was filed. The failure mileage was approximately 140,000.

Upon exiting freeway, all lights on car came on including brake light. When placed in park, the engine would rev. If placed in drive, car would drive without gas given. Car towed to Subaru dealership and diagnosed with thermo control valve defect which seems to be a known widespread issue. Thankfully I was located close to a Subaru dealership however if not, this could cause others to be stranded. Given this widespread issue, a recall should occur to fix this issue.

After starting the car for the first time of the day, letting it warm for a minute or two, I started driving and when I went to stop at a stop sign about three blocks from my starting point I pressed the brake. The engine started to rev immediately so I had to stomp the brake to the floor and push the gear selector to the neutral position to avoid hitting a pedestrian and the dog she was walking. She was within 10 feet of the front of my car when I finally stopped. I have not taken it to a dealer yet since I am sure they will not be able to replicate the intermittent problem. There were no warnings of any kind that this was about to happen. I did note though, that the cold engine temperature indicator light on the dashboard was still illuminated.

Went to car wash,car was in nuetral after after wash finished I put the car in drive and it accelerated into the street at a very high rate of speed my foot was not on the gas.

The automatic shutoff that occurs when the vehicle stops to prevent idling, disengaged two separate times in the span of 4 days. Both incidents occurred at very busy intersections and failed to restart both times. When attempting to restart the car, lights came up on the dash, along with beeping, and failed to restart the car after the light had turned green. To restart, the car had to be completely turned off for about 60 seconds and then could be restarted. To avoid having to experience this issue again, or worse - get into an accident - I took it to the shop where they could not recreate the issue.
