2015 Subaru WRX: engine stalls while driving

Filed Dec 1, 2021 · Engine · PA

Turbocharger intake cracked and causes the engine to have an extremely rough idle and stall. My vehicle has the same issue as the federal safety agency campaign number 16V16200 however it was manufactured before April 10th 2015 so it is not included in that recall.

Driving on the highway at ~70 MPH and suddenly lost all throttle response, the car would not accelerate only loose speed. Engine started to shutter to low rpms, and because of this drastically lost speed and nearly got into an accident with oncoming traffic while moving to the side of the highway to pull over. After eventually pulling over, engine continued to shutter to low rpms and could not hold an idle - would just stall after repeated attempts to start it up. Car was towed to closest dealership and after waiting 4 days finally heard it was the engine wire harness that needed to be replaced. Researching the issue I found that subaru made a design change for the wire harness to prevent water/moisture failure which is most like what happened to my vehicle. Stuck with a $1400 bill due to a design flaw, I decided to purchase a 2020 model which hopefully doesn't have the same issue. After calling subaru of north america and explaining the situation, they offered me $1000 towards the new purchase. It was a kind gesture however I question if it is somewhat admission of guilt for the design flaw. 2015 wrx 138k miles was meticulously maintained with all necessary maintenance completed at proper intervals and oil changes every 3-4k miles.

The RPM drop and the engine stalls, but no check engine lights come on. It only happens in first gear, from what I've noticed.

In a 2015 subaru wrx with a 6-speed manual transmission purchased 03/2015 and delivered to purchase dealer 04/2015. Reported to subaru dealer 02/19/2016 a rough idle with engine rpms recorded between 400 and 1k. Rough idle tripped a check engine light after fueling and cruise control light began flashing. Diagnostic code p0420 reported a fault in catalytic converter. Software update to computer performed resolved issue temporarily. 04/10/2016 at 9.7k miles rough idle issue returned rpms of 400 to 1k again after fueling. In neutral 30-60 seconds after starting vehicle stalled at fuel station. Upon re-starting vehicle check engine, flashing cruise control, ABS, hill-start assist, and traction control faults tripped. Vehicle behavior similar to the federal safety agency recall 16v‑162 where the federal safety agency noted 'due to the use of incorrect material for a portion of the engine turbocharger air intact duct crack, the engine may develop a rough idle, reduced power, and possibly stall'. Complainant believes recall may need to be expanded to include a wider range of vins before listed production dates in recall order.

On my 24k service. Vehicle was checked in at briggs subaru of lawrence, for typical recommended service. After leaving the service center once the service was completed, a short while down the road, I came to a stop at a red light placing the car in neutral. When the light turned green, I was unable to shift into gear to continue. I had to call the service center, and they had to pay for the tow back to the service center. Where a service tech joined me outside, he then proceeded to start the vehicle, while in neutral; revved the RPM to roughly 5k and shifted into first. The vehicle made a terrible grinding sound, lurched forward, and was able to be shifted normally at this point. This stalling\inability to shift into gear\downshift has happened on subsequent adventures in the wrx, while moving and at a stop after this point. At each designated service interval, I reported this to my service advisor; they could never replicate the issue. Proceeding to the 60k service, the clutch has since failed, and I've had numerous stalls where I was unable to shift into gear, the certified subaru repair center, states this is not covered under warranty and in no way does my previous issues with not shifting into gear effect the clutch or any interconnected part thereof. Just imagine having this stalling or clutch failure happen while accelerating to get on the freeway or a busy intersection, like I myself have experienced. This is a major safety concern.

2015 wrx 2.0l manual transmission while driving the car in everyday situations I have had (3) distinct problems associated with the engine/throttle/idle. 1) ghost blip: when coming to a stop, around 5-15 MPH, put it in neutral coast to a stop idle will inexplicably spike from ~700rpm (idle) --> ~1.2-1.5k RPM (for a second or two...like a ghost blipped the throttle). No pressure applied to accelerator. 2) rough idle: while sitting at a stop, in neutral, ~700rpm (idle) --> will dip to ~650-600rpm for a fraction of second & reoccur every 2-4 seconds. Feels like someone lightly shaking your seat from left to right. 3) near stall: while sitting at a stop, in neutral, ~700rpm (idle) --> will dip the rpms low enough that the whole car noticeably shakes...similar to the shake you would experience if the engine were actually about to stall. The rpms will fumble around a bit and then hiccup back to normal idle after 4-5 seconds. All three items have been brought to the attention of the local subaru dealer on (2) occasions w/ the reply unable to diagnose problem and/or it is normal.

Son had just purchased car. Took the car to an area which had an unplowed parking area to test the handling of the car in the snow. Car died while driving and there was an immediate strong smell of the clutch burning. Could not start the car with the car in gear and the clutch pushed in. Car would only start in neutral. When car started could not get the car to go into gear. Was able to get the car push started and driven approx. 0.2 miles to a secure area and then had car towed to dealership where the clutch was found to be burned out. Dealership claims it was driver's error but they sent pictures to me and it looks like the damage does not line up with what they say the problem was.
