    There have been multiple instances where my car has failed to “restart” if the auto-start-stop feature is on. I immediately turn that setting off every time I get into my car because if I pause for too long at a light/stop sign etc.the engine will stall and turn off (without being in park). I have reported this to Subaru on many occasions and they’ve told me to replace the battery, so I did, and nothing changed. I’ve also replaced the starter and that didn’t help either. I’m now unable to turn my car off at gas stations because I’m worried it won’t restart. I just saw that a law suit has opened because of this electrical issue so I wanted to formally report my concerns. This needs to be a safety recall.

    We brought the vehicle in for routine maintenance. They reported that all brake hoses were bulging and at risk of failing at any time. They said that there was a related recall for a similar issue on other CrossTrek's but that ours was not included in the VIN list, so was not a part of the recall. This appears to be a serious component failure which could result in a fatal accident. The fact that this happened with all brake hoses indicates a defective component. We were lucky that we found it and were able to have it addressed before the brakes failed.

    Was driving on highway when all of the lights on my dash illuminated. Eventually I got a warning for oil at temp alarm. Was giving code P2757 and P0700. Looks like this a common issue in Subarus but doesn’t look like it covers anything after 2020.

    - Rod #4 failure of unknown cause, although there is speculation that current failure may be related to a major repair in oil system a year ago. - My safety along with my unborn child’s, husband’s and brother in law’s were all at risk. Another driver had to take evasive action to avoid hitting us in an active fast lane on I-70 going between 65-70 mph. There was no shoulder available to pull off on until a half mile up the road. - Yes the problem has been confirmed from the dealership partially. They did not identify a cause for the sudden failure. However stated it could not be determined if this failure is or is not related to a previous major engine repair made a year ago. - The engine has been inspected by the dealership and warranty company. - There were no warning signals prior to either engine failures. The first one being a year ago for head gasket failure that allowed oil to mix with coolant. With the most recent failure the engine ticked briefly after braking to merge for construction, the oil pressure light followed by engine light turned on 5 seconds before engine completely lost power.

The vehicle was taken to the local mechanic to be diagnosed, and it was determined that the control arms and struts needed to be replaced. The vehicle was not yet repaired. The local dealer was notified of the failure, but no assistance was offered. The manufacturer was not notified of the failure. The failure mileage was approximately 85,000.

    The DCM on our 2021 Subaru Crosstrek is causing a parasitic drain on the battery. It left us stranded several times. We replaced the battery twice in the past 15 months. There is a class action lawsuit against Subaru for this exact problem, but they won't replace it on our vehicle because it has over 45,000 miles. A defective DCM is a widely known problem with many Subaru models. We never received notice of this problem from Subaru, nor were there any warnings, messages, or indications that this was a problem, until we took it to a mechanic for service, who sent us to a Subaru dealer because it had to be repaired by them.

    - Denver, CO

    On [XXX] ~[XXX] PM, at highway speed on [XXX] eastbound near Frisco, CO (a mountain interstate), returning to Denver from Salt Lake City, my 2021 Subaru Crosstrek suddenly and without warning dropped into reduced-power limp mode and began lurching and shaking while the engine kept running. I lost the ability to accelerate or maintain speed. At the same moment the check engine light came on and multiple active safety systems automatically disabled: EyeSight, pre-collision braking, vehicle dynamics (traction/stability) control, and hill start assist. It took about two minutes to manage the lurching, power-limited vehicle across multiple lanes of traffic to reach the shoulder. My partner was in the vehicle. Had this happened on a bridge, a grade without a shoulder, a tunnel approach, or in heavier traffic, I believe a collision was a realistic outcome. The vehicle was towed to a Subaru dealer and diagnosed with a failed Thermo Control Valve. Sixteen trouble codes were stored, including P26A6, P0606, P060B, P2138, P2135, P2122, P2119, P2004, P2005, and P0191. Mileage was 49,983. There was no prior symptom. The vehicle had a full multi-point inspection at the same dealer only 11 days and ~1,400 miles earlier ([XXX]); nothing was flagged. This failure mode is already known to Subaru, addressed by Technical Service Bulletin 09-119-24 and a warranty extension to 15 years/150,000 miles; the dealer repair order confirms the TSB. I am concerned Subaru handles a safety-relevant failure, one that disables collision-avoidance systems at highway speed, through a quiet warranty extension rather than a recall or owner notification. Owners get no warning and discover it only when it fails dangerously. I request NHTSA open a formal safety defect investigation.
