2020 Subaru Outback

The factory 2020 Subaru Outback Wagon is built with a Thermo Control Valve that is, essentially, made out of a composite plastic. As this part is part of the engine cooling system, it is placed under both heat and pressure. While it controls the anti-freeze to the heater core in the passenger compartment, it is also attached under cover to metal fittings. While the car now has about 90,000 miles, this control valve cracked and began to leak anti-freeze on top of the engine. Without cooling, the engine would likely be ruined. Thus, the car required immediate service. When a fault like this occurs, by the way, the Subaru Eyesight System shuts down taking with it various safety features. I had the defective part replaced and it's replacement is not made of composite plastic but, rather and more appropriately, metal. It is my belief that the selection of the orignal part was a design defect ignoring the potential for differential expansion of the parts when exposed to such temperatures. Failure was inevitable. It is worth noting this is not an inexpensive repair as numerous parts have to be removed to access this valve. Likewise, the service representative made note that numerous other customers have had to have the same service.

While we were at a speed of about 55 mph on a state highway, I had just selected cruise control when all the lights went on in the dash--including the warning lights for the brake, the check engine light--and power shut down in the vehicle as if we'd run out of gas. We were able to keep a very slow speed of about 20-25mph, but had to activate the 4-way flashers to alert other drivers that we were losing speed. We managed to get over to the shoulder and call for a tow. We feel this was a catastrophic failure of the vehicle, which endangered both of us. At least we still had power steering. At the dealer, the techs advised us that the issue was likely due to a failure of the electronic thermostat control. The car was in the shop for a week, and was repaired at no cost to us. The thermo control valve and all related parts were replaced. If not under warranty, this would have cost over $2K. We had no warning that this component was failing.

At one year and 7,358 an engine oil leak had to be repaired, and still seepage and monitor is recommended. Then at three years and 28,175 the coolant bypass valve failed and was repaired. Both problems were covered by warrently, but as I live 60 miles from the dealer it was a hassle. I bought the car new in March 2020. I can not recommend Sabaru to people who ask about it and it is highly unlikely I would purchase another Subaru. However it is comfortable and practical and do not plan to sell or trade it for another car at this time. Now at four months after the latest repair it appears to be doing well, and I monitor the oil level.

While driving on the NYS Thruway (I90), I started to pass a Tractor Trailer, I put my blinker on and began moving to the right to pass. There were 2/3 cars in back of me also passing. I was using cruise control and I began to put my foot on the accelerator to finish my passing and move over to the right hand lane to let the other vehicles pass me. However, upon accelerating, my car started to drop power, multiple lights displaying simultaneously indicating a potential problem. (Eyesight Assist, Vehicle Dynamic Control, Brake & Engine Lights), the vehicle started jerking back and forth and I lost all but maybe 5 miles of power. My choice at that time was put my blinker on and try and move to the right - letting the Tractor Trailer pass me on the right and HOPE there was not another vehicle behind so I could move over safely at that crawling speed or go to the left into the gully. This could have been a multiple car collision and maybe fatalities due to the speed and loss of control of my vehicle. After towing to the nearest dealer, they determined it was the Thermo Control Valve. I see now that there is a "service bulletin" and design change of this component and that other Subaru drivers have been affected the same way. This is a very serious situation. I ask, why no recall from Subaru. I have been without my vehicle now for 4 days and may not have it back until next week. I am very fearful of driving that vehicle again.

I just purchased a Outback XT with the 2.4l turbo engine. After more researching with owning the car I discovered these cars with this engine can have a oil pan leak due to the bad RTV sealant applied to the lower oil pan from the factory. I went outside to go look under my car to see if this issue is occurring to mine. To discovery my car has a small oil leak from the rear of the oil pan. it has 31k miles. Further research shows the WRX whom has the same engine also has an issue with RTV falling apart within the oil pan and having the oil pick up tube sucking up the gasket in small pieces. These pieces are then and can get stuck at the top of the tube where a small screen is and can STARVE the engine from oil! MULTIPLE pictures of various shops have shown this LITERALLY. This is a big issue and is common for these engines to have this from the factory many YouTube, forums, blogs are saying this! Search " '22 WRX RTV oil pan pick up tube issue" , "Subaru 2.4l Turbo oil pan leak" , "Subaru 2.4l Oil peak up with RTV" This MUST BE CORRECTED it can cause SEVERE engine failure. THIS NEEDS to be RECALLED IMEDIATELY!

When we started vehicle, a wide array of systems shut down including cruise, Eye Sight, lane detection, auto high bean, adaptive light cornering - essentially anything “automated” or assisted - along with the heating. The car ran at a higher RPM at idle - 2000 vs a usual 700-800 - and rough shifted at speed. Again, as if the automatic transmission lost its sync. The water temp gauge was also off. Have since learned this was the “thermo control valve” and somewhat of a known fault on Outbacks of this year. We were lucky to reach home from the long trip we were on and to the dealership. At the dealership, the service team did not admit this was wide spread. Nor did they tell us there is an updated part from Subaru available. They intend to install the OEM part, which concerns us that in another 40-50k we will face the same $2k problem. We are unlucky that we just went over 60k miles, so this will not be covered under Subaru’s 60k drivetrain warranty. That Subaru is covering a cooling system problem under the guise of being drive train tells me they know they have something to keep quiet.

I pulled into my driveway, came to a stop and planned to back up a short distance to be nearer the front walkway. Before I could shift into reverse the car started to accelerate forward. I slammed my foot onto the brakes which had no effect on the acceleration. The car stopped when the lower bumper hit and ran up onto a large boulder on the edge of the driveway. The car was partially wedged on the top of the boulder but I was able to back it off the boulder, park and turn off the car. I have scheduled an appointment with the service department on February 1st, at the dealership where I purchased the vehicle in June 2020. Of note, I had a routine oil change and service check at this dealership on January 16 with no engine problems noted.

On Dec. 20, 2022, my Outback totally stopped working while sitting at a red light, causing traffic to be forced to maneuver around my car. A kind policeman put out flares until the tow truck arrived. I could not shift into park, nothing electric would work, except the radio continued to play and the flashers worked until it all died. I could not turn the radio off and the seat would not adjust. The electronic screen flashed on and off until it went totally black, after about an hour. This vehicle only has about 21,000 miles on it and was under warranty until 3 weeks prior to the incident. Every time I took it to the dealership, I explained that the electronics had glitches. They always said it was fixed but it never was right. The TomTom navigation system was totally unreliable from day one; the screen went blank and the radio would not work at all, as well as all the screen functions, without warning. The screen would read out that I should keep my hands on the wheel, although both hands were on the wheel. Over and over it had problems which were not resolved.
