Engine And Engine Cooling Problems of Subaru Ascent - part 1

The contact owns a 2019 Subaru Ascent. The contact stated that while his wife was driving at approximately 75 mph, a deer ran across the highway and hit the left driver's side of the vehicle. The air bags did not deploy upon impact. A grayish smoke began to emit from the vehicle as the contact's wife immediately pulled off to the side of the road. Due to the damaged cause by the impact of the deer, the contact's wife had difficulty exiting the vehicle. The contact's wife used excessive force to open a crack in the door, which was enough to slide herself out of the vehicle. The vehicle became engulfed in flames soon after exiting the vehicle, and the authorities were called to the scene. The fire department arrived at the scene and managed to extinguish the fire. The contact's wife sustained bruising to her left shoulder, left leg, and left arm but did not seek medical attention. A police report was filed. The vehicle was initially towed to an independent tow yard and was later towed to an insurance holding facility. The contact stated that the vehicle was destroyed as a result of the fire, but the insurance adjuster had yet to determine a final ruling on the vehicle. Neither the dealer nor the manufacturer had yet been notified of the failure. The failure mileage was unknown.

I was driving and I got check engine light and all safety features disabled while I was in the freeway, luckily I was able to drive to nearby Subaru dealer for inspection and I found out that there was a recall on the engine for this vehicle and when I contacted the manufacturer they asked me to take it for diagnostics and I did that at a Subaru retailer, but the case manager told me that this recall is being completed for the previous owner of the vehicle and cannot help me with anything, which was never disclosed when I was buying the vehicle.

Car has 82,000 miles, has been maintained and requires an engine replacement due to 'sludge'. Reading a lot of forums that indicate this is a common situation with this make and model and likely due to manufacturer's defects.

While driving my Subaru Ascent, a check engine warning light appeared on the dashboard. Shortly afterward, I noticed smoke coming from the engine compartment. I immediately pulled over and turned the vehicle off. Within moments, flames began coming from under the hood. The fire spread rapidly, and within 5-10 minutes the entire vehicle was fully engulfed in flames. The fire originated from the engine compartment. The vehicle was a total loss. Subaru of America was notified on 12/23/2025, but no follow-up or update on investigation has been responded. The vehicle was always serviced with Subaru. This sudden, traumatizing and catastrophic failure with no prior warning.

I hit a deer on CA 395 north, my braking system worked and my air bags deployed, and then my engine immediately caught fire. I’m lucky I was able to get out of the car through a back door. Every police and fire who responded said they have never seen a car catch fire after hitting a deer and I should report a vehicle malfunction.

The transmission on our 2021 Subaru Ascent is slipping and failing to accelerate, rpms reving, and every issue indicator notification light is on. We took the car to our mechanic, then to the Subaru dealership service dept for diagnosis. A full transmission replacement is required plus associated repairs for a cost of $14,543. 98. Service estimate attached. This repair is more than 2/3 of the value of the vehicle. This make/model and transmission type have documented problems and Subaru has previously issued an extended warranty on other model years for this same transmission issue. We are trying to communicate with the Subaru customer service but have had limited response due to the holidays and have not had a resolution yet in the past month.

Vehicle smells of fuel inside the cabin and when parked in the garage. To date the dealer is unable to diagnose the problem. 60k miles.

Oil leak from engine constantly from front differential, rec cvt pump reseal with new trans seal, pump is leaking causing drips ; drain plug is also leaking. Need to replace front and rear pads & rotors at 35k miles which is unheard of. Accessed by suberu dealership.

The contact owns a 2020 Subaru Ascent. The contact stated that while depressing the accelerator pedal to make a turn, the vehicle hesitated to respond. There was no warning light illuminated. The vehicle was taken to the dealer, but was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 61,900.

Camshaft carrier oil leakage need to be reseal. There was oil leakage at 36,000 miles and dealer fixed it under warranty. Now at 80,000 it is doing it again.

While driving the vehicle between 30 - 40 mph, the vehicle will intermittently studder. I have mentioned this issue multiple times to the dealership and they have attempted to fix the issue but the problem still continues. The issue is occurring more frequently and I’m concerned this may create additional engine/powertrain problems down the road.

I was in a front end collision with a deer. Upon impact there was heavy damage to my front end and smoke coming from my engine bay. Within minutes a fire started and only a couple minutes later the entire car was engulfed. No airbags deployed during the accident, there was no collision detected by smartlink and I wasn't even notified of any issues by starlink until the car was completely burnt down and getting doused in water. It is the middle of winter and I couldn't begin to imagine how horrible that would've been had I needed to remove my 3 children from their car seats or if I would've smacked my head and passed out. I was very lucky to walk away unharmed, but many valuables were lost in my car from this.

The contact owns a 2020 Subaru Ascent. The contact stated that the vehicle was taken to the local dealer for routine service, where it was discovered that the cam carrier was leaking from the engine. While having an oil change, the mechanic informed the contact that there were no further leaks found. There were no warning lights illuminated. After driving and parking the vehicle, there was an abnormal odor of oil coming from the vehicle. The vehicle was taken to the local dealer, where it was diagnosed that an overhaul of the engine was needed. While driving, there was an abnormal oil-burning odor coming from the vehicle. The vehicle was taken to another local dealer, adventure Subaru (2269 n henbest dr, fayetteville, ar 72704), who confirmed there was no recall coverage for the failure. The manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 120,000.

Transmission needed a full replacement.

Transmission failure, chugging while driving on the road then slowed down in middle of the intersection, won’t accelerate which is a unsafe situation. It says “check engine”, “break, “eyesight disabled”, “at oil temp” and “transmission”. The speed was stuck to 20mph and engine eas loud. Smelled like something was burning too.

Purchase the car two weeks ago the first night on the way home it was acting up just like it did when I test drove it and was told by the BMW dealership aristocrat motors in topeka kansas that they would fix anything that was wrong with it. On the way home I realized I didn't think it would make it back the 60 miles so I took it to olathe Subaru they informed me that it had had transmission problems reported by the previous owners but their technician couldn't get it to do it again so the people just traded it in instead and then I got the car without them getting the transmission fixed or whatever was wrong. They are actually waiting on Subaru of America to respond to tell them what needs to be done to the car and in the process I have been two weeks with little information of what's going on. I feel the recall should have been done and the car is still a good car it just needs to be repaired correctly. Thank you for your response I look forward to hearing from you please help.

Stopped car turned car off, smoke started to come from under the hood on right side. Turned car on and “low oil” came on, turned car off and exited car. The smell of oil was noted and a light white colored smoke was continuing to rise from under hood. Proceeded to call dealership for advice.

2022 Subaru Ascent limited complained about the tires and brakes to dealership during initial 6k service they said they are fine and sent me on my way. I have taking it in since on 2 or 3 other occasions and same thing. Nothings wrong they checked it drove it and its fine. My wife got rear ended nothing big just replaced the rear bumper and hitch at a certified Subaru collision center. They also did not look over the car since its new they also sent me on my way and I asked for an inspection nothing. I call the dealership a week ago to speak to the service manager so I can get the info for the extended warranty since I am having these issues and its close to 20k miles now and they have not done anything regarding the issue. Waited never sent the info and before I could take it to the dealer ship a few days later I had a blowout. I replaced the tire with the spare but the tire is bald and you cant see it its on the inside there patchy and the brake pads are to small they admitted that they are small for the car and rotors and they would not under a recall but a service bulletin cover the brake pads and resurface the rotors there warped and pulsing its not safe at all. The blow out happened on the sidewall where the bead is where the wheel is mounted just blew. The manager did not offer a vehicle and advised me they had none even with 4 kids I am willing to take any vehicle. I have not received the service and Subaru has not serviced my car as they should and they now claim they have no service records which I provided info and nothing. They want $160 for labor $140 for alignment and $1200 for tires. Its not my fault the service was not done and overlooked I have taken it to that dealership since I purchased it. Called Subaru of America they are dragging there feet the dealership has had my car on the donut since 7/17/24 still waiting on soa I was told 2 business days and still nothing no vehicle had to get a rental. I do not want the car it is not safe. I almost died.

The battery died after two weeks of replacing it, later revealing the alternator failed. Parts are not available, Subaru kept them my safety was at risk because the lights on my dashboard christmas tree'd letting me know something was wrong. Within a couple of blocks I had no power steering and was dying on a busy street. The car was so dead that I couldn't even turn on my hazard lights. The car was jumped by Subaru, the tow truck driver left and the car died two blocks later. This time in the middle of the busy street. The vehicle was towed to Subaru who replaced the battery we bought two weeks earlier. We asked if they check the charging system and they said yes. The battery light was on before we left the lot. We made them keep the car so we wouldn't die in the middle of anymore busy streets. Days later they determined it was the alternator. The car had 26,000 miles on it. I don't know what Subaru did with the parts. They said they needed them as it was a warranty replacement. The battery light never came on before the car died. First the eye sight disabled light came on then many lights on the dashboard flashed on. This happened a couple blocks prior to me losing power. I found the first place I could to get off the road. Two weeks prior when the battery died, the eyesight disabled light came on and the battery light. That time I got home and we replaced the battery. Therefore when the eyesight disabled light came on, I knew something was wrong but thought I had time to get out of the way. Then everything died. The worst part is that hazard lights didn't work.

Over the course of 5 years, a lot has been mechanically wrong with our vehicle. Each service appointment yielded a 'cannot duplicate' response. Recently, my car has been in the service department a few times. My car had recall work performed on a ground bolt, and my husband advised them that the car had a 'rich fuel' smell when starting with the hood open. I've complained since 2021 of a smell when pulling up the mountain. The smell is what I described as a perm solution smell. Each time, the response was 'cannot duplicate. ' in February, I took the car in to have the exhaust inspected because it was getting louder each passing day. I was advised that the entire exhaust needed to be replaced, and I would be responsible for costs. I brought my car home, unrepaired, and called Subaru of America to file a claim through them. I had repeatedly expressed concerns, and nothing was done, yet I'm expected to foot the bill now. Since February 12th, I have been back and forth with Subaru and just made the appointment to get the exhaust work completed, with a small contribution from Subaru. However, this past Saturday, April 13, 2024, my vehicle caught on fire while driving. I am fine, but my vehicle has now been deemed a total loss. As I was descending the mountain, I smelled the same 'perm solution' smell, and shortly after, there was smoke coming from under the hood. The smoke entered the cabin as I pulled off the road. Upon exiting the vehicle, flames and smoke were visible from the hood. I grabbed my purse and ran, called 911, and watched my vehicle engulfed in flames.

The y pipe that connects the exhaust from the engine to the turbo charger, has cracks from poor welds. It happened 8-12 months ago we started to notice that during warm up our Ascent would sound real loud then quiet down once it warmed up. We didn’t know there was an issue as there were no lights that came on and we had no loss of power or mpg. The safety issue would be that we finally took the car in once we started to smell exhaust fumes coming from the car that we would start to smell from inside the car. We had to start to air out the car after warming up if we couldn’t immediately drive away once started. We contacted Subaru and they offered a partial credit for a repair but after researching I have seen they have had recalls in the past regarding similar cracked exhaust manifolds on another model car.

Ascent randomly hesitates when pulling out into traffic. . Both at slow speeds and when attempting to pass on interstate. . Has been at dealer service numerous times regarding this , it periodically 'walking' when parked and ranfom inability to get hatch to work. Is currently at a different dealer service as previous dealer was unable to replicate and unwilling to keep vehicle for more than the hour or 2 of service appt. Prev dealer did replace hatch motor over a year ago. . But still works randomly. . Their fix for this is to manually reset everytime. . As for ' walking ' when parked, my Ascent will very slowly move 6 to 8 feet when parked. . Dealer 'fix' is to only park with parking brake on. Hesitation issue is now worse since prev dealer did 'system update'. . Now rpm drop to 1000 or lower, then after 3 or 4 seconds, car revs to 3 or 4 k & takes off. . During the 3 or 4 seconds of hesitation, I am literally sitting in the middle of the road as the car initially starts to move forward, then literally just sits there until it revs up and takes off. This is random, so no way to record. . And no rhym or reason to know when it's going to happen. Last week it nearly got me t boned by an 18 wheeler when I pulled out across 4 lanes after getting fuel. Have contacted Subaru of America requesting their help but have gotten no reply despite my 7 voicemail left for the assigned rep. My car is a 22 Ascent touring with 17k miles. . Has been at same dealer repeatedly for same issues and their repeated reply us "unable to duplicate, so no issue. ". . I am on Subaru Ascent page on fb. . There are numerous people complaining of same nasty hesitation issue with no resolution from their dealer service. I bought this car with a 10 yr 100k warranty. . Fortunately I have not been financially responsible for the numerous service calls, but I am seriously concerned with being a statistic. . My car is listed as one of the top 10 safest in a crash, but I don't like feeling like a ' test dummy'.

On Friday evening, February 23, 2024 , I pulled onto my driveway and came to a complete stop before driving into the garage . I reached up and hit the garage door remote. When the door began to go up I took my foot off the brake. Instead of creeping up the driveway the car took off like a proverbial "bat out of hell" it was as if I had pushed the accelerator compltely down. To the floor board. The brakes had no effect. I smashed through the garage door,. The car jumped a six inch concrete step up, obliterated the garage cabinets and pushed the contents of the cabinets and garage wall into our family room. The car came to a rest just outside our family room. My son opened the door to the garage and yelled out to me "are you okay" because the engine was still racing he said "get your foot off the accelerator' my reply was I don't have my foot n the accelerator". I then tuned the ignition off and the ordeal was over. . It appears that the engine continued to recieve fuel irregardless of the position of the accelerator. , the automatic braking system failed miserably and the the forward collision warning was malfunctioning. I am waiting for the insurance company to remove the car from the garage and do a structural assessment. . Because there may be serious structual damage I want the insurance company to remove the vehicle less the second floor collapses onto the garage. My son was on the couch just seconds before the wall "exploded". The couch was moved eight feet across the room. If a piece of debris came through the windsield I also might have been injured. The potential for serious injury to others in another set of ircumstances also scares me. The malfunction came without warning. The damages will be in the tens of thousands of dollars. I am blessed that no one was injured or killed.

I have encountered a series of persistent issues with the vehicle since its initial purchase, indicating fundamental deficiencies that warrant thorough consideration and resolution. Commencing with brake malfunctions at an exceptionally low mileage threshold, the recurrent necessity for brake replacements, despite being facilitated by the dealership on four separate occasions, underscores a notable deficiency in the vehicle's manufacturing or assembly process. Furthermore, the manufacturer's offer of $10,000 in exchange for signing a waiver relinquishing my right to file a claim is indicative of their acknowledgment of the vehicle's inherent flaws. Subsequent to this agreement, additional complications have arisen, including persistent window malfunctioning, electrical faults, exhaust system irregularities, and most notably, transmission failures, with repeated complaints culminating in a catastrophic breakdown witnessed by the dealership's service team. In light of these recurring issues, the manufacturer's proposition to repurchase the vehicle while crediting back the $10,000 initially offered and prorating mileage solely from the transmission repair fails to address the cumulative impact of the vehicle's deficiencies. It is inequitable to discount the mileage accrued during the earlier brake-related concerns, especially considering the ongoing nature of the vehicle's mechanical shortcomings. Arguably, the rescinding of the $10,000 offer necessitates a reevaluation of the waiver's validity, as its premise was contingent upon mitigating specific concerns, which have regrettably persisted. Moreover, the manufacturer's refusal to accommodate a reasonable request for mileage adjustment from the onset of the brake-related issues undermines the principles of fairness and consumer protection. Given the manufacturer's reluctance to engage in arbitration and their apparent disregard for addressing the comprehensive history of issues encountered.

During an inspection at the dealership in December 2023, the tech found the oil pan to be leaking. It was resealed during the same visit. Approximately 8 months later, the same problem was found again at the dealership. It was again resealed. Upon further research, this appears to be a recurring problem on similar vehicles.

2019 Subaru Ascent was taken to mechanic due to jolting between 1000rpm and 1500rpm. Car was not throwing any code. Mechanics then did other test and it was determined the transmission is failing. Car only has 70,000 miles on it. Also, when car is started at times, there is a very prominent cloud of smoke that comes from the exhaust.

The contact owns a 2020 Subaru Ascent. The contact stated while driving 10 mph, the accelerator pedal was depressed, and the vehicle had started jerking. The rpms became elevated however, the vehicle failed to respond. There was no warning light illuminated. The vehicle had not been diagnosed or repaired by an independent mechanic or dealer. The manufacturer was made aware of the failure and confirmed that the VIN was not included in a recall. The failure mileage was approximately 42,000.

Only 3500 miles on new 2023 Subaru Ascent and it won"t start. I have had to give it a boost four times already, anytime I need to use it. I check to make sure there are no lights left on. Just staying parked from one day to the next and it won"t start. I have an appointment at the dealer service dept. At 1:45 pm o June 5th, 2023, for them to hopefully resolve the problem. I'll have to give it boost to start the car and drive 125 miles to the dealer. Hope the car makes it there. On your website, the 2019, 2020and 2021 models had a recall for the battery draining because of faulty wiring. We would think the manufacture sabaru would have taken care of this problem on the newer models.

Car has been not able to roll up driver side window for a year randomly. Suddenly 3 years old and battery is draining and rab and eyesight and engine light on. Took in and saying can’t replicate window after they did replicate it 3 months ago and did not solve issue. Did battery parasitic draw and numerous parts of car are draining battery. Cannot find source.
