Subaru Crosstrek engine failure problems

Filed Oct 31, 2026 · Engine · NY

The Crosstrek has a broken cam carrier. It is a design flaw and known issue of Subaru Crosstrek. A broken or leaking cam carrier is dangerous to the vehicle because it directly compromises engine lubrication, structural integrity, and electrical safety. The cam carrier acts as a structural housing that keeps the camshafts securely in place and seals oil inside the top of the engine. Its liquid sealant fails and is bound to creates several severe operational hazards. The cracked seals has critical oil escaping. If the oil level drops too low, the engine can experience severe internal friction, leading to scored camshaft journals and rod knock while driving. Ultimately can lead to engine failure. Further, it is an immediate fire hazard, especially in the Crosstrek boxer engine design with the oil commonly dripping downward onto high-temperature exhaust components like the catalytic converter or exhaust manifold. Additionally, oil leaking can travel to the spark plug wells and causes misfires, loss of acceleration, and sudden stalling. Moreover, oil leak destroys electronic and sensors including the wiring harness and serpentine belt. Also, toxic cabin fumes from leaking oil burns can pull into the vehicle’s HVAC system and creates an immediate health hazard that can impair driving the vehicle. It is well-documented by Subaru of this issue stemming from factor sealant application (RTV) rather than a wearable maintenance item. Specifically, Technical Service Bulletin TSB 02-192-24 regarding engine oil leak diagnostics. There are 95,000 miles on the Crosstrek only. Subaru Service quoted me $6,101.54 to repair. Please issue a recall on the 2016’s Crosstrek to mandate Subaru to fix the dangers at no charge to the customer. Thank you.

Car was driving at highway speed when I noticed that the car was shifting. Started driving up the hill and then a loud clanking noise started. Pulled over and put the car in park only then did the oil pressure light come on. Metal shavings were found in the oil. The number 3 rod bearing broke cause catastrophic engine failure. Mechanic inspected the pictures of the other rod bearings, the main bearing and the crankshaft and there was no damage. A mechanic at a Subaru dealership confirmed that the number 3 rod bearing is a known issue.

- 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.

On 06/26/26, while traveling at highway speeds, the vehicle suffered a sudden, catastrophic loss of motive power in active traffic due to a blown out/melted Cylinder 4 ignition coil. This unexpected engine failure forced raw fuel into the exhaust system, causing an immediate internal thermal meltdown of the catalytic converter, rendering the vehicle entirely undriveable and creating a severe highway safety hazard. This vehicle was previously serviced under the federal safety agency Campaign 21V264000 (Subaru Recall WRE-21), which was intended to permanently remedy an ECM software defect that over-energizes and melts the ignition coils. Subaru of America (Case # 260630-2101598) is denying coverage, claiming that because the recall was executed 90,000 miles/5 years ago, and because the current software Calibration ID (CID) matches their post-recall database, the thermal melting is standard "wear and tear." I am filing this complaint because a safety recall remedy must be permanent and effective. The physical evidence, a melted plastic coil housing with a hole blown through it, is an engineering impossibility under normal wear and tear and proves that the original software patch failed to permanently mitigate the high-voltage overloading defect. Over a 5-year period of gradual thermal degradation, the defect reoccurred, creating the exact highway hazard the recall was mandated to prevent. I request a federal investigation into the long-term efficacy and failure rates of the WRE-21 software reflash.

. I expect a full recall on this model years and relative MY vehicles with this specific engine due to its obsolescence in the subsequent years. I feel as if I was sold a lemon and defective engine that will eventually become a death trap Dear Bloomington Subaru Service Manager, I want to reiterate that this is not an isolated incident limited to your facility. Over the course of this vehicle’s history, I have visited more than five different Subaru dealerships — including White Bear Luther Subaru, Miller Hill Subaru, Walser Subaru, Morrie’s Minnetonka Subaru, and your own Luther Bloomington Subaru — for recurring ECM and engine-related concerns. Despite multiple ignition coil replacements, repeated ECM flashes/reprogramming, and assurances that the most recent updates would permanently resolve the issue, my Crosstrek continues to suffer from clunking, rattling, difficulties accelerating, rough idling, and even complete stalling when idling or in hot temperatures. At my most recent visit to Bloomington Subaru, the ECM was not loaded with the current software, ECM C1424 and C1422 and Diag Trouble Code P0011 code. There are 5-7 Subaru bulletins about ECM and these codes. I had this b4 2yrs ago yet the dealership won’t assist with repairs or costs associated with this defective oil control valve part as well as the defective design in the ECM / ECU and this specific engine in the 2019 Crosstrek, of which is no longer produced or manufactured. The ECM or Oil control valve has since been “replaced” and swapped with other components in future generations of Subarus this is defective & mechanically related, not from wear and tear or personal useThere is a recall where the camshaft can break and the PCV too leading to complete catastrophic engine failure, which is a safety issue and expired, but despite 5 ECM flashes, 3/4 sets of ignition coils my vehicle still struggles with the same issues today, costing me $750 and months with my car in the shop, recall this engine

On [XXX], 1 wheel lug nut seized up on the lug and then the lug snapped off when trying to remove the nut. On [XXX], 3 lug nuts seized up on the lugs when attempting to remove the lugs. On both occasions, I have had to bring the vehicle in for repairs to have the lugs and nuts replaced. Total cost of these repairs approx $250. On [XXX], I called Subaru of America (1‑800‑782‑2783) to report the issue of lugs nuts seizing up on my Subaru (3 today and 1 in December 2022). The representative took down my information but other than that, was not very helpful. I asked if she could have an investigation done to see if this is a systemic problem with the 2018 Crosstreks or with Subaru in general. Her response was for me to “Google the issue myself” and then call them back if I found out anything. She offered essentially no help. In more than 40 years of working on cars, I have never had a lug nut seize up on a lug stud. Since this has now happened 4 times in the last 15 months, on the same vehicle, this seems to be a systemic problem and should be investigated.

In three separate incidents while car only shows 70 in fuel indicator, my 2016 Crosstrek stalled while driving on a highway. I have brought my car to Subaru dealer, but they cannot find anything wrong with my 2016 Crosstrek. In each of the three separate instances after waiting on the side road for 30 minutes, I was able to restart the car and drive home. My car just had a new engine air filter replaced.
