Subaru Crosstrek check engine light comes on

Filed Nov 4, 2026 · Engine · AZ · fire

I was moving from Chicago to Phoenix. No issues for approximately 14 hours of driving/900 miles of driving. Passed a semi and my vehicle started to make a clicking noise. No check engine lights came on and the oil temp didn't spike up. Decided to get to the nearest repair shop but on the way the noise got louder and eventually the engine started smoking. Pulled over and a fire had started underneath the vehicle. Still, no lights came on and the temp gauge was not high. Luckily we were able to put out the fire before it caused any damage. Oil had exploded all over the engine and a hose had bursted off. Again, no warnings/lights ever came up. Vehicle could have exploded and caused major harm/death to me or anyone nearby on the road. Vehicle has been towed to a Subaru dealership and they have done a tear down inspection. Currently waiting on Subaru of America to do an inspection themselves.

I filled up my 2023 Subaru Crosstrek with gasoline and a short time later the Check Engine light came on as did the warning lights that the safety features associated with the EyeSight system indicating it was no longer functioning. It encouraged me to get the car checked immediately. It turned out that I had not completely tightened the gas cap. I tightened the gas’s cap hoping the safety featured would reset - it didn’t. I contacted Subaru and they said it should reset after a few stops when the engine is shut off. I was on a road trip from Pennsylvania to Maine on a weekend so there was no place to get it checked or reset. We stopped multiple times along the way and it never reset. There were no Subaru dealers at our destination in Maine. Finally after some research I found out I needed disconnect the battery for at least 30 minutes and the car’s computer will reset. It worked. My point is that a simple loose gas cap will TOTALLY DISABLE all of the car’s SAFTY features associated with the EyeSight system create a safety problem totally unassociated with a loose cap or vapor leak. I can understand the warning lights coming on telling the driver to have the car serviced immediately. I do not understand why it needs to disable the collision avoidance, line crossing warning and other SAFETY FEATURES associated with EyeSight, making the car less safe.

At 45,261 miles, the check engine lights came on and the vehicle would barely start and run. It was towed to a dealer and was again diagnosed with carbon build-up on the intake valves. This is the second occurrence in just over a year. It was repaired, and again, other than the repair, nothing was done to prevent this from happening a third time!

On XXX while driving my brand-new 2026 Subaru Crosstrek with approximately 63 miles on the odometer, the vehicle suddenly lost acceleration. The AT Oil Temp warning flashed, followed by the Check Engine Light and multiple EyeSight and driver assistance warning lights. I immediately pulled off the road because I did not feel it was safe to continue driving. My [XXX] grandson was in the vehicle at the time. The vehicle was towed to the selling Subaru dealership. The dealer diagnosed transmission trouble codes P0700 and P0752 and determined that an internal valve body solenoid had failed. Because the solenoid is not serviceable separately, the entire valve body assembly was replaced under the manufacturer’s warranty. My concern is that a brand-new vehicle experienced a sudden loss of acceleration at only 63 miles, creating a potential safety hazard for my family and other motorists.

- 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.

I own a 2019 Subaru Crosstrek Hybrid with recurring fuel-system and EVAP failures that I believe present a serious safety risk. On 12/9/2025, the vehicle experienced a total loss of motive power while I was driving in dense traffic on a busy expressway. The vehicle suddenly lost propulsion in the middle lane and slowed down to a near crawl, creating an immediate risk of being struck. The event was captured on dashcam. The dealer inspected the vehicle but found no cause. On 1/5/2026, the vehicle again lost motive power. It remained at the dealership for approximately two months. Some roughness was noted, but no cause was identified, and I was told to return if the problem became more prominent. I am concerned that an intermittent defect capable of causing sudden loss of propulsion remains unresolved. The vehicle has also had recurring difficulty accepting fuel since it was new, along with check-engine lights and DTC P0452. The refueling problem progressively worsened. On 6/20/2026, the vehicle would not accept fuel normally at all. The pump repeatedly shut off while the tank was still empty or nearly empty, and fuel backed up, spilled, and overflowed from the filler neck. This creates a fire hazard and exposes occupants and bystanders to gasoline. Subaru previously performed TSB 09-82-23 but did not replace the fuel tank. The TSB allows tank replacement when resin residue is found in affected fuel-system components. Fuel was analyzed and found clean, yet multiple downstream EVAP components became clogged or restricted. The dealer later replaced the charcoal canister and EVAP filter but found no cause. I am concerned that the recurring fuel/EVAP restriction, gasoline spill during refueling, and two unexplained losses of motive power may share an unresolved root cause. Subaru has advised me only to return if symptoms recur. I do not believe it is safe to wait for another highway loss-of-power event or another gasoline overflow.

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 the federal safety agency open a formal safety defect investigation.

In the middle of driving car stuttered, engine light went on, and car stalled. Unable to restart, Engine cranks but would not turn over. Had car towed for repair. Diagnostic shows engine coil short causing blown fuse. Subaru has an active recall for this identical issue for my same year and model 2019 Crosstrek but the recall does not cover my VIN.

Dangerous stall in traffic due to ignition coil failure. Ignition coils and spark plugs were replaced during the WRE21 recall campaign only 13k miles ago back in 2021. Stopped at red light awaiting to turn left when the vehicle started shaking violently. No check engine light came on though. When the light turned green, the vehicle was barely able to move forward then it completely stalled before pulling over to the curb. Since the tail of the car was sticking out into traffic a bit, it was a downright dangerous situation. Car had to be towed to dealership and took them 5 days to diagnose and fix the problem. Ignition coil and spark plug replacements costed $1500. Don't think the recall fixed the root problem and this could potentially happen again.
