2021 SUBARU CROSSTREK Forward Collision Avoidance Problems

Traveling at speed of 30MPH. A tocoma truck in front of me suddenly stopped in road lane. Driver said that his vehicle made an auto assist stop were the brakes lock. My 2021 Crosstrek eyesight/braking system failed. I saw the truck stop but the system failed and I went into the back of a large truck. There is a witness who is happy to talk with you. He saw the truck's sudden stop and my crosstrek failure to stop. My car is totaled. I have the police report and have reported this to my insurance company.

Check engine light came on while idling. "Eyesight" tech turned off along with certain associated safety features. Next day, vehicle struggled to ignite. Came to a complete stop at an intersection, released brake, stepped on gas, and the car rolled forward as if in neutral and bucked up and down like a rodeo bull.

While driving in the left lane on a three lane highway (about 70mph) the car's automatic braking system engaged. The car would not accelerate creating a very dangerous situation on a congested highway at night. Luckily, we are able to navigate to a brake down lane without a collision. The check engine light, Eyesight light and RAB light turned on. The car would not function normally and was towed to a Subaru dealer (Patrick Subaru, Shrewsbury MA). Diagnosis was a failure of the Engine Coolant Bypass Valve P26A6. Other failure codes were: P0087, P2004, P2005, B2806, B2C22. I was told this is a known problem in Subarus of certain years, but, instead of recalling, the company has extended the warranty on the malfunctioning part. This incident happened without any previous warning and caused a life threatening situation for us and those around us.

Suddenly warning light "Check Engine" came on along with Eye Sight malfunction warning. "i RAB off" "Check Engine" Automatic Emergency Braking not working. Yes, available for inspection. Not confirmed yet by dealer. It is the weekend. There were no unusual symptoms prior to ADAS malfunction.

Subaru Eyesight system engaged randomly with no forward obstacles. Dashboard lit up, signaled alarm, and brakes engaged causing the car's nose to bottom-out. This has happened twice, thankfully at low speeds and thankfully without another car rear ending me. I'm worried this will happen on the highway. Eyesight system is generally unreliable. Random lane departure warnings and obstacles detected where there are none.

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.

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.

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

Subaru Pre-collision braking activates when no danger present. It detects exhaust steam or smoke as an obstacle. Approximately February 25th of 2021: While acceleration from a stop light in winter, Eyesight falsely detected the exhaust of the car in front of me as a danger and slammed on the brakes to a full stop causing the car behind me to bump into me. Thankfully this driver was paying attention and no damage was caused. This function overrode my foot being on the accelerator. Late Spring of 2021: While using cruise control on the highway, 70+mph, a diesel truck accelerated to merge. The eyesight again detected the exhaust as a hazard and slammed on the brakes causing the drivers behind me to take evasive actions and put them at risk for no reason. During both incidents, the collision warning lights fully activated. I spoke to the dealership about these incidents and was told to turn off the pre-collision system on cold days and watch out for diesel exhaust.

The automatic braking system engaged at highway speed while changing lanes with no other vehicle or object in front of the vehicle. I was accelerating to change lanes when the sensor started beeping and the car slammed on the brakes causing a sliding skid. I was able to maintain control and fortunately there was no one behind me. I believe the eyesight control malfunctioned. I do not believe this is a safe feature as it not only puts my safety at risk but also the safety of anyone on the road around me.

MY VEHICLE IS EQUIPPED WITH EYESIGHT, WHICH IS A SUBARU TECHNOLOGY THAT INCLUDES ADAPTIVE CRUISE CONTROL, FORWARD COLLISON WARNING/BREAKING, LANE DEPARTURE WARNING, REAR AUTOMATIC BRAKING, ETC. SUBARU CLAIMS THAT WINDSHIELD REPLACEMENTS MUST USE SUBARU GLASS DUE THE OPTICAL CLARITY OF THE WINDSHIELD AND THAT THE EYESIGHT SYSTEM MUST BE RECALIBRATED. THIS IS A $1339 COST (VIA SAFELIGHT) TO REPLACE THE WINDSHEILD. I HAVE 8400 MILES ON MY VEHICLE, AND I AM GETTING READY TO HAVE THE SECOND WINDSHIELD PUT ON THE CAR. THE GLASS SIMPLY BREAKS TO EASILY. FIRST INCIDENT, A ROCK HIT THE WINDSHIELD AND IT CRACKED ABOUT INCHES WHILE TRAVELING THROUGH ALBUQUERQUE, NM ON I-25. SECOND INCIDENT HAPPENED TODAY ON I-25 WITH A BARELY PERCEPTIBLE SOUND, AND THE WINDSHIELD HAS A CRACK ABOUT 6.6 INCHES LONG. I AM NOT SURE WHAT THE ISSUE IS WITH SUBARU WINDSHIELDS, BUT LOOKING IN OWNER FORUMS, IT'S A PRETTY COMMON OCCURRENCE. THE FACT THAT I AM AVERAGING A NEW WINDSHIELD EVERY 4200 MILES IS RIDICULOUS. I HAVE BEEN DRIVING FOR 35+ YEARS AND HAVE HAD TO REPLACE A WINDSHIELD LESS THAN THREE TIMES. WITH THE SUBARU, I AM DOING IT ALMOST EVERY 4-5 MONTHS (SO FAR).

THE LANE KEEPING FEATURE WILL RANDOMLY CAUSE THE VEHICLE TO VEER TOWARDS THE CENTER LINE AT A VARIETY OF SPEEDS AND UNDER A VARIETY OF CONDITIONS, REQUIRING IMMEDIATE DRIVER CORRECTION TO AVOID CROSSING THE CENTER LINE. NO ACCIDENT HAS OCCURRED BUT THE SYSTEM IS NOW DEACTIVATED. IN ADDITION, THE COLLISION AVOIDANCE SYSTEM DOES NOT RELIABLY ACQUIRE A VEHICLE AHEAD IF THAT VEHICLE IS STOPPED AND THE SPEED DIFFERENTIAL IS >30-40 MPH. WITHOUT DRIVER MANUAL BRAKING, A CRASH WOULD OCCUR.
