Assist Problems of Subaru Crosstrek

This a second report following a visit to the dealer for system check. At that service, we were advised that no issues were identified, we were told that sunlight could cause the Subaru “eyesight” system to disengage. Today, 25 February, the vehicle eyesight system continues to disable and enable itself seemingly at random. This morning, we travelled on well marked roadways with overcast skies (no sunlight to cause problems). The system repeatedly disabled and enabled itself. In addition, on a street with vehicles parallel parked along the curb, the vehicle reported an obstacle and began braking for no apparent reason. This has been reported to the dealer. We are awaiting a response. It does seem as if there are some faults within the eyesight system.

Vehicle lane keeping assistance switches itself off and on while driving. After first occurrence, dealer response was that such behavior is not unusual when sun is in front of the vehicle. Second occurred while driving with sun behind the vehicle and on either side of vehicle. This has been reported to dealer but there has been no response.

Lane-keep assist function has stopped working correctly. Warning light on dashboard. On a 3 lane freeway, on left side of vehicle the car drifts over the dividing line into traffic before there is a nudge. On right side car goes way over the line and doesn't nudge at all. I've taken it 3 times to dealership fod repair and they dismiss my concerns.

A/c drain clogged and let water into car drenching all carpets below all seats- (2) electronic devices below driver and passenger seats malfunctioned and caused all eyesight and safety systems to fail along with check engine light turning on, all safety systems failed, all wheel drive offline and power steering went manual.

I have had several of the safety systems on the vehicle shut off suddenly. Twice, I have taken the vehicle into the dealership to get it looked at and now I will have to do so for the third time. It is pretty concerning because it has to do with all the safety features.

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.

My lane keeping assistance feature was turned on by someone else. Nobody has access to my vehicle and I keep it armed when away from the vehicle. In addition, I noted the vehicle was well within the street lines. There was no reason to take control of the wheel. Given I was not driving outside street lines, I worried about the possibility that someone was controlling the wheel. A dealer has not confirmed or reproduced the problem. The vehicle has not been inspected regarding my issue; however, it is a brand new vehicle. No accidents have occurred. There were no warning signs. I finally noted the lane keeping assist icon was turned on. But again, there was no reason to take control of the wheel. I have also noted the door locking system has been behaving strangely, unlocking, locking unexpectedly. My key fob works properly. The incidents started to happen at the beginning of December 2022. The latest occurrence happened more recently. As a result, I decided to report the incidents. Thank you.

I just leased a new '21 Crosstrek limited. With only 90 miles on the car, while driving on the highway using the adaptive cruise control and lane keep assist, the vehicle started aggressively jerking over towards semi trucks (while going 70mph)- I had to give significant input to not be pulled into a semi truck. I turned off the feature then turned back on. Again, it was hard jerking only towards semi trucks. Drove back to the dealership. Their mechanic took for a drive and said the exact same thing, that it was "sketchy" and jerking towards semi trucks. It was suggested I bring back if the "condition persists" which would mean risking a fatal collision with a semi. I contacted the gm of the dealership and explained what was happening and he said to being back again and they'd get a field tech from Subaru to test. Their service manager test drove and noted the same thing, as did the field tech. "severely pulls to the right as trucks pass. Test drive vehicle and found that when using lane centering, vehicle is quite jerky and pushes towards centerline, especially when larger vehicles like a semi trailer is present. Recommended calibrating eyesight camera and test driving again". They calibrated the eyesight and I picked back up. Drove back on the highway and turned on lka, this time the steering was completely taken over and jerking all over the lane and flashing telling me to keep hands on the wheel when both hands were very tight on the wheel. It's continued to jerk all over while using lane keep assist and when I try to override the steering to avoid a collision the wheel feels like it's fighting me. It's extremely dangerous. The car now has 300 miles and I'm terrified it's going to kill me and it's putting everyone on the road at risk. I had the same tech in my '19 impreza limited and didn't have a single issue. I fear there is a serious defect with the eyesight and lka. No codes are present. They said vehicle is operating as designed, it's now more more erratic.

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. ## #vpic# 1 - check digit (9th position) does not calculate properly #vpic#.
