Recently reported ENGINE problems on 2010 Subaru Legacy

While crossing a busy street i was forced to brake hard and quickly because the car ahead of me suddenly stopped. my subaru's engine then stalled. i was almost hit from both the rear end and from the side because i couldn't start my car fast enough. the dealership indicates that this is due to a bad torque converter on the cvt transmission. this is a known issue with the 2010 legacy, but they will not and the nhtsa won't force them to do a recall. however, my car is 16,000 miles outside the extended warranty they established when they found out about the problem. they indicated that i could have resolved this issue by july 2018 at no cost. however, since that date has past i'm out of luck and must pay for it out of pocket. also, the car did not have any of these problems then, so they wouldn't have done preventative maintenance for it anyway. therefore, i must now drive around a car that stalls whenever i brake. i am going to get in an accident. i just hope i don't die.

Tl* the contact owns a 2010 subaru legacy. when the contact purchased the used vehicle, she had it inspected by an independent mechanic. the mechanic did not find any failures at the time; however, the vehicle kept stalling when driving. an independent mechanic stated that the vehicle needed a new transmission and hardly had any fluids. in addition, there were a multitude of failures with the vehicle, including the brakes, engine, and transmission. the contact spoke with the federal trade commission to file a complaint with the dealer from where the vehicle was purchased (rad auto shop, 101 n main st, sharpsburg, pa 15215, (412) 782-2886). the contact was referred to her state attorney general's office. the contact stated that her bank would file a claim on her behalf if the dealer did not refund her money. the dealer and manufacturer were not contacted. the failure mileage was 141,000.

While turning into a parking lot, the check engine light, emergency brake light, the cruise control light and the stability control light all came on and started blinking. parked the car and shut off the engine. let set for an hour. started again. ran it home and all lights previously indicated stayed on doing the same thing. car ran fine though in all instances.

Car often shudders & stalls when coming to a stop on a city street also will sometime stall when going slow to turn into a parking space.

Tl* the contact owns a 2010 subaru legacy. the contact stated that while the driver was driving and came to a stop, the vehicle stalled without warning. the driver restarted the vehicle and was able to drive normal. in addition, the contact stated that each time the vehicle shifted down and come to a stop, it would stalled. the failure recurred numerous times. the contact called ed reilly subaru dealer, located at 150 manchester st, concord, nh 03301, (603) 225-0200, and informed the dealer of the failure. the technician advised the contact that it was the torque convertor that failed and was a known issue. the vehicle was not taken to a dealer and was not repaired due to the diagnostic and repair fees. the manufacturer was not notified of the failure. the approximate failure mileage was 120,000. the vin was not available.

Tl* the contact owns a 2010 subaru legacy. while driving approximately 35 mph, the contact came to an abrupt stop and the engine stalled without warning. there were no warning indicators illuminated. the vehicle was taken to a local dealer (brunswick subaru 2992 center rd, brunswick, oh, 44212) where it was diagnosed that the torque converter needed to be replaced. the vehicle was not repaired. the manufacturer was notified of the failure, but did not offer any assistance. the failure mileage was 136,000. the vin was unavailable.

I put my foot on the brake at an intersection (came to a hard stop) after deceleration and the engine hesitated, then stalled/stopped completely. i must put the car in park and restart the engine to remedy the stall. this has occurred 4 times in the last week. in two situations, the vehicle behind me had started to accelerate, but my vehicle was not in motion because i must put the car in '(p)ark' to restart the car. this is a safety hazard because the car stops so abruptly.

Per service bulletin # 16-90-13, the car will stall when coming to an abrupt stop. part of the time, the vehicle will stall when coming to a normal stop as well. this happened once while city driving when a light went from red to green as we were approaching. we were down to under 5 mph and went to accelerate again to continue with the flow of traffic. before i could release the brake, the car stalled and almost caused us to get rear ended. so that along with the inconvenience and danger of dying at stops will push us into performing this costly repair asap. the stalling can occur sometimes at every stop, and sometimes it will not happen for multiple stops. the torque converter is a known issue, and is to be replaced with a more updated model with different internal components. i contacted subaru and they informed me i was outside of my warranty so it was completely up to me.

Torque converter- stalls when coming to a stop

The problem is with the torque converter failing and the dealership wants me to pay $2,100 which i'm not doing and it's an ongoing problem with subarus with cvt transmissions which makes its stall when pressing on the brake when it happens to me every single day now ever since the dealership looked at it last.

On the 2010 subaru legacy 2.5gt the under hood emissions label shows a misprint. the label includes the word "air" indicating that the vehicle should have a emissions related air pump. the vehicle does not! this was apparently updated on the 2012 models but not the 2010. this error on subaru's part is causing me to fail california's emissions test. i now have to visit a referee because of this error.

When making a hard break the rpm's will drop so low that the vehicle will begin to shudder and then eventually stall. this i find is dangerous because there have been times where i've been at an intersection and had to hard break and i have to turn my car off and turn it back on before i can move out of the way. there is a recall for my same year 2010 for the subaru outback manual, i have the cvt transmission so i'm sure they differ but essentially described as the same issue. i notice it more at the beginning of my drives if i drive for over a half hour i don't recall experiencing the issue any longer. it's been progressively getting worse over the last few months. i read online that sound correct to the problem with a reflash some corrected the problem by replacing the torque converter and some a new transmission. i have been putting my car in neutral to keep the rpms from dropping out so low that the car stalls out

Car shuts off while breaking. used to happen when stopped but now happens a few times a day when just trying to break. it almost caused an accident a few times. the car shuts off while in drive, lights flash on the dash, i have to put in park and turn the key off. it starts up fine, but happens again and again. it's been going on for about half a year and is getting worse. no one can seem to find any fail codes or anything.

Stopping vehicle quickly and engine shudders and stalls at any speed. my car has 120k miles and has been doing this since just under 100k miles

I parked my car after traveling about 100 miles. i was sitting still with the engine running. i have a manual (6 speed) transmission, and the car was in reverse, but the clutch was in all the way and my foot was off the accelerator and on the brake. suddenly, without any warning, i heard a noise and the engine quickly started to rev and the tachometer went all the way to the red line. after i recovered from the surprise, i tried to kick off the engine by depressing the accelerator quickly and releasing it. my action had no effect. i then turned the engine off with the key and it cut off. i have driven the car today and not had any recurrence of this nor have i had any instance of this type prior to last night. *tr

Car stalls when slowing down or braking to stop. no error codes or engine light warning. car starts right after but stalls again frequently. checked all fluid levels ok. happens with hot or cold weather.

I had a major safety issue with my 2010 subaru legacy while driving on the freeway. the car was doing approximately 50 mph and i accelerated to change lanes and all of a sudden the car lost all power and eventually came to a complete halt right in the middle of fast moving traffic. i turned on my hazard light, put the car to park and restarted. the car would start but would shut down slowly in the next 2-3 seconds even before i could put it to drive and accelerate. i noticed that all the lights in the dash like traction control, check engine, etc all lit up and the car just slowly died. after trying it one more time (with same results) i shut off the car completely and started calling aaa for towing. after about a minute when i tried to re-start the car, it sprang up to life normally (i.e. without a slow shut-down like the prior two times) and accelerated when i put it to drive like nothing had happened. i was then able to get off the freeway for safety and popped the hood to see if there was anything on the surface that i could find wrong. everything looked fine, i was even able to get back home all on the freeway normally. i tried to stay on the right lane and simulate the same (i.e. doing decent speed and then accelerating), but everything was normal. sunday being mandatory dealership closures in nj i was not able to bring it to the dealership. the whole incident was completely random and was needless to say extremely dangerous and stressful. i have contacted subaru of america and waiting for their response. in the interim i wanted to post this to nhtsa in case other such incidents have been reported. *tr

On wednesday, november 19, 2014 my son left for work at his usual time and started the subaru. immediately, the engine roared at full throttle, and the vehicle took off down the street, where it jumped the curb and crashed into a tree at 45 mph. distance traveled was less than 400 feet from where it started. based on an eyewitness account, it is presumed that the vehicle suffered an unintended acceleration mechanical issue outside of the driver's control. emergency service personnel arrived within minutes, and he was taken to the major metro-area 833 bed hospital (level 1 trauma center) where he was admitted to critical care. he died peacefully and without pain on wednesday afternoon, november 26, 2014, at age 37. subaru of america was notified of this incident on friday, november 21, 2014; a detailed description, police crash report, and 18 pictures were provided, with a request for them to inspect the totaled vehicle and download available information from the black box recorder/event data recorder. (note: as of today, november 29, 2014 no action has been taken).

My car stalls when i come to a stop. it is an automatic cvt car. he happens all the time. could cause an accident when i stop and then accelerate. *tr

I had entered a parking space, and was slowing to come to the end of said parking space. the car rapidly accelerated, and i could not stop it with the brake. i hit the concrete at the end of the space at full speed, which stopped the car. i noticed that the impact had slipped the gear into neutral. when i turned the car back on, it registered that it was in cruise control. i have never used cruise control on any this or any other vehicle. i have bruising from the seat belt, and neck pain from the impact. the vehicle is not drivable due to damage to the front end, and a rumbling noise in the engine with poor response when accelerating. *tr

Problems with electronic throttle control or throttle bodys causes the vehicle to hesitate for several seconds upon initial acceleration. this has nearly resulted in accidents on several occasions when merging or pulling out into traffic. problem of vehicle stalling when stopping at a light started at the same time (related problem). drives fine under all other conditions. dealer unable to assist. *tr
