2021 SUBARU CROSSTREK Complaints

This is my 3rd Subaru. This one has now has 3 windshield cracks. 2 spontaneous, one by a tiny pebble. The photos are all from this one vehicle.

In early November 2023, NHTSA Recall Number23V755000 was issued for my 2021 Subaru Crosstrek. I was not notified by NHTSA or Subaru even though none of my contact info has changed since buying this new vehicle. I believe that this creates a potential safety issue if owners are not made aware. I found out through Carfax in early January 2024.

Check engine light came on while driving. All Advanced Driver Assistance Systems were disabled. Code is P26A3: Thermo Control Valve is faulty. This is a known problem and Subaru has addressed it by redesigning the Thermo Control Valve in 2021. Unfortunately there is no recall on the models fitted with the prior design that have a high rate of failure.

The contact owned a 2021 Subaru Crosstrek. The contact stated that while parking and the brake pedal was depressed, the vehicle accelerated unexpectedly and collided with a wall. The collision was at the front of the vehicle. The air bags deployed. The driver sustained arm, leg, thumb, back, and nose injuries. Medical attention was needed. A police report was filed. The vehicle was towed to an impound lot. The manufacturer was not notified of the failure. The failure mileage was approximately 1,300.

There are occasional times (perhaps once or twice a month) where the vehicle does not respond with the expected acceleration of a depression of the accelerator pedal. Specifically, the vehicle "lags" when I depress the accelerator pedal. While I have not experienced a dire situation or collision because of it, I believe it might cause other drivers to experience a safety incident: a driver might want to perform a fast maneuver with elevated risk but not receive the expected acceleration. For example, I was once making a U-Turn with traffic oncoming about 2,000 feet away. I needed to make the maneuver swiftly but my vehicle lagged. I would like to report this issue in case other owners of the Subaru Crosstrek Plug-In Hybrid are also experiencing.

Was driving on highway at approximately 65 mph. Check engine light came on. Engine started to stop responding to gas being given to car. Pulled off to exit highway approximately 1 minute after check engine light came on. At bottom of exit, car completely lost power. Attempted to put vehicle into park and wouldn't shift. Started to see smoke coming from engine and then shortly after started to see flames coming from engine. Immediately exited vehicle and called 911. No one was injured. Subaru indicated fire started as result of external influences. Insurance company's 3rd party auditors were not able to determine cause of fire.

The issue is the Engine Coolant Bypass Valve. This causes the Engine to not take in as much coolant resulting in the engine getting much hotter than it should, thus putting those in the car’s safety at risk. This could ultimately lead to a fire and/or cause the car to suddenly lose power. My car already refuses to go above 3000 rpm’s and is very laggy when driving. The car itself shows a code that the bypass valve needs replaced & the check engine has come on. However, Subaru has failed to acknowledge that this is an issue amongst most of their vehicles since 2020. This issue also disables the Subaru Eyesight which is in control of adaptive cruise control, pre collision breaking, and sway warning. With those features now disabled, the car has lost the Safety Package that Subaru boasts. I have read on many online forums that this has been an ongoing issue now for many customers, a bulk of which experienced total engine failure. This lack of responsibly is putting many lives at risk on the road every day. I hope this helps shed light to this issue to Subaru & that this part is recalled so that Subaru must pay for the repairs instead of the car owners. Also, the repair part is around $500 & maintenance must be done by Subaru which is another $400-500 for labor. My opinion is they are using this defect as a way to make easy money on many customers since 2021.

While driving on the highway in the slow lane (furthest to the right), traveling at approximately 50 mph, I came to be behind a tractor trailer. Before I had a chance to pass the tractor trailer, it switched lanes abruptly. My vision past/beyond (in front of) the tractor trailer was heavily obstructed by the massive vehicle itself, so I could not see that in front of the 18-wheeler there was a mid-size sedan traveling at approximately 5-10 mph in the same active highway lane I was in. I had almost no time to react, and neither the Automatic Emergency Braking system nor the Forward Collision Warning system engaged. Both of these systems should have activated to prevent the collision and/or minimize injuries and damage. I subsequently collided (harshly) with the aforementioned sedan.

When I make a forward sharp right or left turn, the tires "shudder". It feels like they are skipping or I'm hitting little bumps in the road. Crown Subaru in Chattanooga, TN, told me the center differential was bad, so I would need to replace the transmission for $11,000. I took it to a mechanic for a second opinion who specializes in Subaru repair. They scoped it, fully checked the transmission, bearings...anything they thought it could be and could not find anything wrong with the transmission or bearings. Nothing that could be causing the shuddering. After visiting a few discussion sites, many Subaru owners have this problem and they are told many different things from their dealerships; all ranging from "it's normal on these models" to an exorbitant repair like a new transmission. Note: when Subaru told me I needed to change out the transmission, they did not say for sure that would fix the issue.
