Problems with 2010 Subaru Forester ENGINE

On average, the 2010 Subaru Forester starts to “feel” problems with the ENGINE and its various aspects after 89 342 miles.

Recently reported ENGINE problems on 2010 Subaru Forester

Hesitates when driving off or slowing down ,goes dead when pulling into traffic.sometimes the engine jerks and shakes. plugs have 30,000 on them after tuning up.yellow lights will not come on and nothing shows up on diagnostic check. extremely dangerous.

While driving, "check engine" light, cruise light & traction light began flashing. dealer said catalytic converter had to be replaced. repair done & dealer said, "if it doesn't 'take,' we'll know soon." three weeks later, same thing happened. this repair is on top of a major gasket replacement done just a few months earlier because the gaskets were leaking. car has about 115,000 miles & has been serviced regularly.

Leaky headgaskets...

Left side head gasket leaking oil onto the exhaust manifold. subaru faulty head gaskets. something needs to be done about the faulty head gaskets. only 85000 miles on the engine.

On routine oil visit change, dealership informed me the head gaskets were leaking slightly but didn't need immediate repair. i had noticed no symptoms. on next visit for an unrelated problem, was told they needed immediate repair at a cost of more than $2,000. a quick online search confirmed that this is a common complaint among forester owners. i let the dealer make the repair but complained to subaru corporate, which wrote off some of the cost but still cost me hundreds to fix.

When driving the car starts to jerk and hesitate alot when accelerating happens quite frequently which causes the check engine light to come on so then you take it get it plugged in on little machine tells you something so you fix that issue thinking it's all better but nope still continues to happen might be good for a few weeks to a month but always continues to happen and makes it impossible to go up hills or anything because there is barely any acceleration.

I had pulled into my company parking lot and was backing into my parking space. i pulled forward, applied the brake to shift into reverse. as soon as i took my foot off the brake pedal, the car zoomed backward. i jumped a curb, went through very thick bushes and landed on top of a small audi parked in the lot behind ours. i had to turn off the car to stop the engine. i was too in shock to take photos but others did and i can add later, with the police report when it's completed, if that's possible. i have no idea how fast the car was going. much too fast to be backing into a parking space. auto body shop across the street helped to disengage the cars. no towing nec.

Problem of sudden acceleration while stopped in traffic with vehicle in gear. this happened twice. both on city roads. once at a traffic light. and again while waiting for traffic ahead of me. feared i would collide with cars ahead of me, but extremely firm pressure on brake pedal avoided this. also have cel on. code indicates misfire on cylinder 4. that was determined at the service center of burdick's drivers village in cicero, where i purchased the car used almost 2 years ago. the service advisor at drivers village told me there was nothing further they could do. he recommended i take it to romano subaru, which i did. the service center at romano subaru replaced an ignition coil, but the problem remains. romano wanted to drop the exhaust system and inspect the engine, but i declined. spark plugs and wires were also replaced by my mechanic. i have also switched to top tier fuel, which hasn't had an effect. i like my forester, but the issues with the cel and sudden acceleration make me ponder a trade. the car is a 2010, with 96,300 miles.

Leaking oil at 55,000 miles, have read online that there are problems with head gaskets in this model

I respectfully request that the subaru forester 2010 be investigated for defective head gaskets as they appear to blow suddenly and unexpectedly, rendering the vehicle unsafe for driving. my vehicle has approximately 74000 miles on it and has been serviced regularly and nearly exclusively by the dealer. while driving the car, i noticed the coolant light came on and immediately pulled into an oil change service station to have them check on and replace the coolant and change the oil. afterward, i drove the car home but noticed that when i was nearly home the coolant light came on again and i could hear a low whistling noise. it was too late that evening to take the car to the dealer. the next morning, on my way to get the car checked/serviced, the lights for coolant, check engine, traction control and cruise control began flashing intermittently. was advised of blown head gasket(s) and that the car was unsafe to drive. dealer did repairs, including replacement of engine block, which took approx 6 weeks. this issue happened suddenly and without warning, in a car that has been well cared for and has relatively low mileage for its age. this issue rendered the car unsafe to drive at the time it occurred. i am unsure if the issues have been fully resolved yet as i got the car back and the check engine light came back on 2 days later. it is currently back at the dealer for analysis. however, i wanted to report this because i am hoping other car owners might be protected from any potential accidents/safety incidents due to faulty head gaskets. thank you and please feel free to contact me with any further questions.

Hello- i am experiencing continued issues after recall: 16v-738. i began attempting to resolve this issue in september of 2016. the issue impacts the secondary air system and my vehicle would not pass ca smog. i have to have a passing smog to renew my ca registration. i failed smog and sent the vehicle to my mechanic. my mechanic performed diagnosis and determined stored p2441 and p2443 codes (secondary air valves open). around the same time, october 2016, subaru released recall: 16v-738. this addresses a single relay in the secondary air series. i proceeded to schedule and take my vehicle into rancho grande subaru in san luis obispo. i also opened a claim with subaru corporate customer support sr #:1-19856672948). subaru began working on my vehicle mid october 2016 and placed me in a rental suv. i did not receive any communication from subaru, so i followed up. the tech informed me the vehicle is ready to be picked up mid november. i visited, picked up the vehicle, drove it 3 miles and heard a loud screech from the secondary air pump. i returned the vehicle, informed the tech and he rudely responded "was that noise happening when you dropped it off". no, i responded and they resisted placing me in a rental for another 3 weeks. late december, i followed up once again due to lack of communication and the vehicle was ready 3 days later. i drove the vehicle 200 miles and now the same check engine light is on, traction control light is flashing and vehicle intermittently accelerated. i checked the codes and the same codes remain. i feel the scope of components requires all components in the secondary air system to be replaced. the faulty relay was on the on position and has exhausted all the components in the series. this is a nation wide issue do http://www.subaruforester.org/vbulletin/f87/secondary-air-valves-p2443-p2441-63347/. t

I was heading to work on rt 80 w in nj when my car's engine began to make a knocking sound. it would not accelerate, and the steering wheel became extremely difficult to turn. as soon as possible i got into the right-hand lane and exited rt 80 via exit 34b, rt 15n towards sparta nj. i knew there was a gas station at the exit and was just barely able to pull in when the car died. at that point the steering wheel wouldn't turn at all and the car died. the aaa driver told me the car had burned through all the oil (he checked the oil tank; it was completely empty.) i had the car towed to milford pa where my place of business is as i had perishables i had just bought for my cafe with me that needed to be refrigerated. my mechanic said exactly what the tow truck driver had said. the engine blew due to the car burning up all the oil. no warning lights ever came on before the engine died. since buying this car i have had to replace the catalytic converters twice, both times before the car had reached 50,000 miles. i have had to have the ignition coil replaced 3 times in under 3 years. the car is a lemon, but no signs were evident until i hit 34,000 miles or so. it is a miracle that i didn't hit or harm anyone on rt 80 when the engine died, or that i wasn't harmed. subaru of america is very unhelpful; they keep telling me my car needs to be at a subaru dealer for them to "open a case", even though i explained i had perishables with me and had to keep them cold. i asked if subaru would tow the car for me, but they said no, as it has too many miles on it. when i asked them about why the warning lights never came on, i was told that my vehicle is "not equipped" with those lights, even though i know it is as they came on when the catalytic converters melted and the driver's manual for my car instructs the driver as to what to do if the lights come on.

Tl* the contact owns a 2010 subaru forester. the contact stated that when the vehicle was taken for a routine inspection, the technician informed that the engine was leaking oil and the head gasket needed to be replaced. the vehicle was not repaired. the manufacturer was notified of the failure. the failure mileage was 160,000.

The subaru forester 2010 failed the oil consumption test performed by subaru. the cause from a subaru bulletin states that the #1 and/or #4 intake valve guide insertion hole was improperly machined, permitting oil to enter the combustion chamber. this occurred on the subaru forester 2010 models as well as 2011 legacy/outback, and 2011 impreza. this is a safety issue because more than 1.5 quarts of oil is consumed after only 1100 miles driven. in alaska you could be stuck in the frozen interior if this defect caused the engine to overheat and malfunction while traveling. subaru will not fix the known defect. subaru states it's out of warranty and the bulletin doesn't apply to my vin number. this should be a recall issue and subaru should be required to fix the problem. they will only provide $500.00 for a $5,000 fix.

After work, i got in my car and started it up. check engine light came on, followed by traction control and tire pressure lights. this was odd because these lights had never been on before. i started to drive home--it was too late to bring the car to have it checked out. i live a minute and a half from work. the cruise control light then came on and flickered in no particular pattern. then, about 45 seconds into my 90 second drive, the temperature gauge light came on. the weather was about 50 degrees and rainy. when i got home the engine fan was spinning really fast. i popped the hood. no smoke or anything visibly wrong. at roughly 2:10am there was no way i could bring it to get the issues looked into. so i left the hood open to let some heat out and when the fan slowed and then stopped, i closed the hood and went inside. about 10-15 minutes later, during which time the car had been stationary and the engine had been shut off, i heard a pop sound. it was a strange noise and i got up to check it out. it was a massive engine fire. it toasted the engine and melted a good portion of the front end. the fire dept shattered the windows and peeled the hood back. the car is totaled. the fire was just feet away from my house on one side, and the neighbor on the other side. had i been asleep the fire could have spread to my house or my neighbor's, potentially killing people. it was one of the scariest things i've ever experienced. there is a video on youtube with something similar (search subaru engine fire). the car is a 2010 forester xt, completely stock. it has been very well maintained and has about 85,000 miles on it. my mother originally owned it. she bought it brand new from the subaru dealership and i bought it from her.

Dashboard warning lights (traction control, cruise control and engine light) are lit because of a problem with the catalytic converter. it is very costly to fix the catalytic converter. because we cannot afford to fix the catalytic converter, we are left with no traction control or cruise control. also, if something horrible happens to the car, we will not be warned about it since the engine light is on for the catalytic converter. i am not alone. so many people have the same problem - just look at the hundreds and hundreds of people on the online subaru forum. this is totally unacceptable. when so many people are having the same problem through no fault of their own, then it is the manufacturer's responsibility to solve the problem. i am requesting for this problem to be addressed in a recall of the catalytic converter for the 2010 subaru forester.

Tl* the contact owns a 2010 subaru forester. while driving at various speeds with the accelerator engaged, the engine light illuminated. the vehicle was taken to the dealer. the technician diagnosed that the head gasket needed to be replaced. the vehicle was not repaired. the manufacturer was notified of this failure. the failure mileage was 70,000.

The vehicle has been maintained in accordance with the manufacturer's manual. recently the "service engine" light came on. immediately the vehicle pulled into a lot and checked under the hood. the oil was low, so oil was added. it was about 90 miles home, so it was started back up and entered a toll road. after about 10 minutes a slight burning oil smell was noticed so the vehicle was immediately stopped on the shoulder and shut off. after checking the engine compartment oil was noticed on the bottom of the vehicle. a flat-bed tow-truck was called and transported the vehicle to the subaru dealership that normally services the vehicle. the dealer diagnosed it as "internal engine failure" due to the engine running low on oil. 10 minutes after the check engine light came on. recommends replacing entire engine with used engine. *tr

Excessive oil consumption issue on 2010 subaru forester. last oil change @ 72,328 miles. vehicle ran out of oil at 74,979 miles. [documentation available on consistent regular maintenance.] *tr

While cruising at 40 mph up a slight incline, the engine suddenly jerked a few times, then stopped. i was able to pull to the side of the road. the car was towed to my mechanic's garage where he diagnosed the problem as a failure of the air conditioning unit to open the valve which allows cool air to enter the cabin. the air conditioning unit literally froze, resulting in the belt which engages the engine stopping and causing the pistons to stop while the valves kept moving. severe engine damage resulted which required machining of cylinder heads and replacement of many parts. if this incident had happened going at high speed on a highway, serious injury or fatality may have occurred. *tr

While in my driveway, i started the engine, stepped on the brake, put the vehicle in drive and it accelerated. i swerved to miss a trailer parked in front of me, pushed harder on the brake, the vehicle stopped, the engine raced for a few seconds and then idled normally. i got out, looked at the floor mat and it wasn't touching the accelerator. it hasn't happened since, but the car doesn't get driven much. *tr

Sudden acceleration from full stop. the vehicle had exhibited sudden acceleration 3 weeks prior but the dealer did not find any problem. from a full stop, the vehicle was placed into reverse at which time the engine revved to full throttle, overriding the brakes, resulting in the vehicle backing uncontrollably and stopping on top of a boulder with the back wheels off the ground approximately 4 feet. the incident was witnessed by a bystander. the vehicle undercarriage severely damaged and not drive-able. photos and a police report were submitted. *tr

Sudden acceleration incident. parked at the county recycling center, when placed into drive (full brake pressure required to shift out of park), the engine accelerated to maximum power causing the car to drive away uncontrollably and overriding the previously applied brake. immediately shifting to neutral, the car was brought under control and then functioned normally. driver and passenger were witnesses and unharmed. the vehicle was taken to the dealership for inspection. no cause was found. *tr
