2021 SUBARU CROSSTREK Engine Problems

The contact owns a 2021 Subaru Crosstrek. The contact stated that while his daughter was driving at an undisclosed speed, the vehicle inadvertently lost motive power in the middle of the roadway. The contact stated that several unknown warning lights were illuminated. The vehicle was towed to the dealer, who diagnosed a failure with the battery. The vehicle was repaired, but the failure reoccurred. The vehicle was towed to the dealer and diagnosed with head gasket failure. The vehicle was not repaired. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA Hotline for assistance. The failure mileage was 120,000.

While driving down the freeway, all the warning lights came on and the engine sputtered and cut out. As we were in the left lane on a busy freeway, it put us at considerable risk. We were able to get to the left shoulder and get towed off the highway. This was caused, I later learned, by a faulty electronic thermostat which caused the system to fail.

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.

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...

The engine part that seems to be the issue is the starter. The car has an auto cut off when stopped at lights and other times you stop the car. The car's engine is supposed to restart as soon as you take your foot off the brake. As the car's engine heats up, the car's engine does not start immediately after removing your foot from the brake. The issue becomes greater the longer the engine has been running. On longer drive times, the engine hesitates enough that it seems like it might not start. The dealer has replaced the original starter due to the same issue. The new starter is less than 3 months old and the problem is again happening. No warning lights or indications that the engine will not start immediately upon removing your foot from the brake. The greater amount of time for the engine to restart...

Engine shut off at a stop sign and the dashboard lit up like a Christmas tree with alarms sounding. Couldn’t get car restarted. Towed to Subaru dealer and they said there was a connector cable to the starter that was defective. Replaced at no cost.

My brand new Subaru ignited in the engine compartment, burst into flames and exploded while I was driving it.

Had intermittent total loss of power for about 1/2 of a mile.

I was crossing two lanes of a very busy ocean front street when the engine “bogged down” . I let off on the gas pedal and then depressed it again, which then caused the engine to go off. I the quickly restarted the engine and was able to get out of the way of oncoming traffic. This was the only time the engine failed, but on about three or four previous times, the engine “bogged down” when I depressed the gas pedal, but recovered after I quickly depressed the pedal again.

SHUDDERING - CVT belt or pulley not working properly? JERKING, HESITATION - Crosstrek will not go when the gas pedal is pressed or hesitates or pauses for a moment after the gas pedal is engaged

THE ENGINE STOP START FUNCTION CAUSES THE ENTIRE CAR TO SHAKE WHEN GOING FROM ENGINE OFF TO ENGINE ON. IT IS WORSE WHEN YOU ARE STOPPED AND THE STOP START RE-ENGAGES WHILE YOUR FOOT IS ON THE BRAKE.
