2020 Subaru Ascent Transmission Problems

Vehicle: 2020 Subaru Ascent (Build Date: March 2020) Component: Power Train – Automatic Transmission – Hydraulic Pressure Sensor / Wiring Harness The vehicle developed a flashing "Transmission Service" warning and check engine light. It was inspected by a certified technician at Lithia Reno Subaru.

Bolt holding the driveshaft support bracket backed out causing driveshaft to come out. This is a known issue with the 2019 and 2022 Subaru Ascents and have active service advisories but Subaru of America does not recognize it for the 2020 models even know it is also happening in the 2020 vehicles. If the driveshaft would have came out at a high speed it could have caused a crash.

CVT transmission skips in high gear and shudders randomly while driving down the road. Randy Marion in Hickory NC is where we purchased and replaced the rear transfer clutch and insists the problem has been corrected. Our regular mechanic and Moderna Subaru of Boone NC both agree the transmission is bad.

On or around May 20, 2022, I was driving on a highway. I took an exit ramp to merge onto another highway. I accelerated and merged in front of a bus and was headed towards a toll plaza when I felt something and heard something.

2800 miles on vehicle. Today lost power twice going up steep hill (electrical functions still intact, was accelerating uphill and was similar to shifting into neutral then re-accelerated after 10-15 seconds, driving approx 30mph). Narrowly avoided collision due to slippery road, did briefly roll backwards before braking.

Oil Leak(s) (found cam carriers leaking, front timing cover leaking, oil cooler leaking, upper and lower oil pan leaking. recommend engine reseal). Massive oil leaks found in car due to RTV sealant.

Between October of 2021 and February of 2022): Shuddering (like driving on rumble strips) and sluggish transmission (slow to respond acceleration and sometimes jumping when depressing the gas pedal) - reported this multiple times to dealership but was told they couldn’t replicate what I was feeling/experiencing.

My mother pulled off of Interstate 85 in North Carolina and while preparing to turn of the exit ramp the car lurched forward and then back. The transmission chain had snapped, and it seems similar to what was going on with the 2019 Subaru Ascent. This one is 2020, and had 16000 miles approximately.

I was crossing a four lane road going 20mph when there was a loud noise, which sounded like my transmission, then I could not accelerate my car. Thankfully I was able to coast across the road without being hit by another car to a safe parking spot. My check engine light, check transmission, and check eyesight lights all went on.

I stopped at a stoplight, when it turned green I stepped on the gas, the car lurched forward but would not move, engine was running. I was sitting on a 4-lane highway and my car would not move. Warning lights then appeared on my dashboard.

Fyi: report is being submitted by co-owner in nc. Reported incident occurred in florida. At around 20,000 miles the dashboard lit up like a christmas tree and the vehicle began having acceleration issues.

I have had my lane assist come on by its self a few times, which is very dangerous because it seems to take over and will pull on the steering wheel.

Replaced front multi plate transfer clutch at 96,987 miles.

The CVT transmission has failed and been replaced three times despite proper maintenance. Subaru has replaced the transmission multiple times under warranty, but the failure continues to recur. •First CVT replacement at 50,542 miles •Second CVT replacement at 88,175 miles •Third CVT replacement at 92,832 miles This shows repeat failure, not wear-and-tear.

My 2020 Subaru Ascent experienced a sudden failure of critical safety systems due to CVT fluid leaking through the transmission pressure switch into multiple electrical components. This fluid leak damaged several wire harnesses and the Engine Control Module (ECM). The check engine light came on and all Eyesight safety features disabled.

Ever since our car went in for re-programing CVT drive chain it progressively has been having a problem of something slipping in drive and in cruise control. feels like a loss of power and a feeling chatter from transmission. Now when you put it in drive it makes a jerking noise.

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.

The vehicle hesitates like it doesn’t want to get up to speed, despite pressing the gas pedal to accelerate. The RPM needle bounces.

For the past month, the engine revs up higher than normal at slow and highway speeds. It had the feeling of the engine skipping gears and staying at to high of an RPM even with the accelerator being eased off. Initially it was brought to Subaru service dealer in November and they could not replicate the issue.

CVT jerks the vehicle and stutters when at certain rpms, making long car rides very uncomfortable. Feels like whiplash every so often. Very dangerous when trying to speed up to pass another vehicle because the vehicle doesn't respond and accelerate as it should.

My car had a CVT drivetrain recall which has been labeled as "repaired" because I brought it to the dealer, however, the issue still exists and my car has been to the dealer 5 times already concerning this recall. The symptoms of the CVT drive train that I am experiencing are: shuddering (dealership vocabulary) at approximately 20 MPH (approximately 1500-2000 RPM).

Driver front wheel was making a noise when turning or slowing down. In Sep 2022, the dealership said they repaired it, but had we not brought it to them, where the front wheel meets the axel would have caused us problems.

Transmission is lurching and surging when driving. Pressing gas pedal from a stop the belt continues to slip. Took it to Paul Moak Subaru they claimed to do the inspection told me they don’t do test drives for malfunction checks.

Transmission still slipping when accelerating between 20-30mph. Brought car in for recall but it continues to have the same issue. AC stopped working even when leak was fixed.

The manufacturer has failed or is unable to remedy this safety recall for the vehicle in a timely manner. Subaru of America has failed to repair after (1) year. The consumer has/will incur costs to make vehicle available during the limited times for CVT recall issues.

Since last NOV 2021, I have had this Ascent into the shop several times due to a 'chirping' or 'speaking' sound that comes from the underside of the middle o/t vehicle. I have come to find out through the service department that the primary differential has a batch of defective parts, and the entire differential needs to be rebuilt (21 parts total are being replaced).

I was informed of the recall of my 2020 Ascent and my Subaru dealership gave me a 2021 Ascent loaner car. but it is going on 2 months and no information when my car will be fixed. At this point time I don't want my car anymore if they can't FIX IT.

Bought in December 2021 had dealership fix breaks before bought then again after 3000 miles then again after 5 000 miles. Brakes still shudder and emit loud noises. Have only had 6 months and breaks are bad again.

The 2020 Subaru Ascent has had a recall notice for nearly six months now (Manufacturer Recall NumberWRK21 NHTSA Recall Number21V955000). I experience a low frequency sound accompanied by rapid vibration lasting only a second when reapplying acceleration after a brief pause in acceleration. This occurs very inconsistently and not yet something replicable at the dealership.

Something in car drains battery frequently not while the vehicle is running but after it’s been off for a few hours when no lights have been left on, Subaru dealership refuses to admit there’s a problem. This leaves me exposed to being stuck in unsafe situations with a dead battery. No warnings ever come on to alert me the battery is draining.

Recall ID 21V-955 affecting the drive chain. Vehicle is showing signs of this (vibrations while driving). My families safety, two toddlers ages 2 and 4 are at risk.

The contact owns a 2020 Subaru Ascent. The contact stated that upon parking on an incline, the gear shifter failed to move out of the park and excessive effort was needed to move the gear shifter. The contact also stated that an abnormal grinding sound was coming from the vehicle.

Loss of power (intermittent) while driving at a constant lower speed and occasionally during acceleration. Additionally, when going up a hill the automatic transmission drops in gears which significantly increases rpms then once on flat road the vehicle takes some time to change gears. If I hit the gas pedal once at the top of the hill, the rpms go past 3.5.

CVT began slipping intermittently around 28000 miles. This usually occurs in the 55-65 MPH range at 2000-3000 RPM. Slipping is indicated by approximately 300 RPM change and a noticable hesitation in vehicle motion.

The transmission occasionally slips, resulting in a momentary rise in engine revs and a slight lurch. I assume that this is related to the known transmission issue for earlier ascents, but mine is not included in the affected VIN number group. Other people traveling in the vehicle with me have noticed the issue and remarked on it, so I am not imagining it!

When driving, Ascent sudders while under normal highway conditions. Has had all 4 recalls completed but this specific event has been consistently present even after each recall was completed. Now that Ascent is out of powertrain period, Subaru of America acknowledged transmission finally needs complete replacement but only offering portion as a one time offer.

The manufacturer has known about this at least since December 2021. Their solution is to reprogram the transmission control unit. Waiting nine months or more for a reprogram seems excessive to me.

Dangerous automatic back up brakes apply when not needed when backing up a trailer on incline (driveway for instance). This can only be disabled by finding the disable button on the video infotainment system, and re-engages as soon as the car is shifted to drive as is often necessary in the back and forth of parking a trailer.

Driving down the road the entire car started vibrating and felt wobbly when I got above 20mph. Pulled over to check tires and under the car, no obvious issues found. Turned off then back on the car, same issue above 20mph.

Jerky acceleration between 35-50 MPH. CVT "switching gears" up and down. Noticed at 600 miles.
