2023 SUBARU SOLTERRA Forward Collision Avoidance Problems

Solterra 2023 bought Dec 23, 2022 Report: 1. Unintended Acceleration while parking. 2. No braking power till few feet away from fence. Incident:1. Prior parking, owner had accidentally touched the Regenerative Braking Paddle which is right next to turn signal lever. 2. Approaching a row of trees within 2 feet, the Solterra lurched forward, mowed down 2 trees and accelerated while owner's foot was on brake; owner yelled at passenger" NO BRAKES!!" Car accelerated onto backyard, passed a children's swing set, kept going onto the grass. Finally,car stopped by itself within several feet of the fence which faces busy Jericho Turnpike road. 3. Date & Time: 4/14/2025 about 1:30 PM. Owner's Doubt: If the brake system is hydraulic, then pressing brake pedal would stop vehicle; Malfunction: Regenerative Brake System generated acceleration instead of braking ! Recall Service Appt. with Dealer on April 27, 2025: Subaru WRG 231, WRG 241 and repairing front. Done: NHTSA Recall ID 23V-064, February 2023 = Subaru WRE-23. Experience once before: A few seconds of no braking during crawling traffic jam, about a year ago. Vehicle is available for inspection at owner's driveway.

My Subaru Solterra EV was parked in the driveway of an Airbnb in Virginia. We were about to depart to return home. Vehicle was turned on and driver commenced to back out of the driveway, however rear safety warning activated as car neared a bush. Driver stopped vehicle, then placed in Drive in order to pull forward a few feet to negotiate putting the car in reverse to leave the driveway. The car then lurched forward with great force and collided with the corner of the house we had been staying in, causing significant damage. Two concerns arise: 1. Why did the car lurch forward with great force to begin with? 2. Why didn’t the automatic emergency braking system not activate? I shiver when I think what might have happened if a person had been standing in front of the car. The car is now being repaired by a shop selected by my insurance company. Once completed it needs to be thoroughly tested to determine if this could be an ongoing problem. I theorize a software glitch my be responsible.

Vehicle stopped dramatically at low speed in snow while sensors were freaking out and flashing reverse breaking sensor problem. Car has been in shop for 6 weeks. My concern is the breaks auto/over corrected and caused my car to slide in snow.

During any precipitation, primarily rain, the adaptive cruise control fails to sense vehicles in front of it. This became alarming as the vehicle began to speed up and get alarmingly close to the other vehicle, causing driver to slam brakes. When looking at the cruise control display, the vehicle never showed another vehicle in front of it.

Started the car, dash had multiple warning lights for "drive start control system", "ev system malfunction" and "systems not available" (all safety systems were off). Took car to dealer, they said the car stored no codes, reset the car, took it home. Two days later- same thing happened but also this time the car had NO HEAT. Luckily the heated seats worked but it was 20 degrees F and I had to drive my mother and sister home (which was 90 minutes- a VERY long time to be without heat). Thankfully it did not snow which would have made the car undriveable due to the inability to defrost the windshield. Car went back to dealer (ziegler subaru of Kenosha WI), they have stated (thus far) two valves are bad and need replacing. i am in several online forums with other Solterra drivers, some of which are experiencing the same issues and being told the cause is the same valves, or the compressor. Lead times to acquire these parts are 2+ months. I have had my car since April 2023 and it has 9000 miles and to have it fail, with no heat or safety systems, is a danger to myself and others on the road.

The S pedal regenerative breaking shuts off randomly, causing the vehicle to stop breaking, and the need for an immediate use of the brake pedal.

We hit a stationary deer at night. Afterwards, we found an open recall: WRG23-1: Forward recognition camera reprogramming 2023 Subaru Solterra, but Subaru refused to investigate as they claim animals (suddenly appearing) are a carve out on their liability. However, the deer wasn't leaping, it was already frozen in the road. The headlights only illuminated its knees, too late for the driver to stop before impact. It could have just as easily been a person, or other heavy road debris. The incident was on a dark highway bypass, with slight left curve, so poor headlights hampered the driver & automatic systems from stopping in time. The headlights angle down (tilts & dims from brights automatically for oncoming cars) instead of illuminating the road properly, neither the driver nor the braking system can detect an object. The regular lights have an abnormally short distance. Only the brights setting illuminates a sufficient braking distance, & those can't be used with oncoming traffic. The headlights have a hard limit on the top, instead of 2 circles of light. The driver, also an engineer, said that the camera needs a certain level of lighting to detect objects, & they probably didn't test these systems together on a dark country road. Normal illumination could have prevented or lessened the damage/danger, swivel headlights would have been best. A driver needs a certain distance illuminated for braking distance at speed, unless the camera is radar or infrared: it needs light too. The front 1/3 of the car was peeled off, causing over $15k in damages. Several body panels ripped off, the wiring harness was ripped out. There were no warnings before the impact. No automatic braking occured. No airbags were deployed. There is a police report. Road was dark, clear and dry. The driver was sober, attentive and going the speed limit. A camera reprogramming without a headlight fix will not solve this safety issue, & we told Subaru as much. This situation may apply to Toyota.

Under certain circumstances when using adaptive cruise control the car can accelerate towards a stationary vehicle. The last time that it occurred I was using the adaptative control at 35 mph and was approaching a stop light with the car correctly detecting a car in front which my car had detected and was slowing to allow adapt to the speed of the car that was ahead. The car entered a turn lane on the left and there was another car directly in from of mine and it was stopped at the light. My car began to accelerate to the speed which is was set at and didn't detect the car in front which was stopped at a traffic light. I had to quickly apply my brakes to avoid a collision. My car had recently been updated with an update to it's software. An update had been applied to the front camera's software.

Ihad something happen 3 times with the car on my drive to work. It was raining and vehicles ahead of me were kicking up a significant amount of mist in front of my Solterra. I was using the adaptive cruise control feature and it is supposed to follow cars in front of you and slow down or speed up (to your max set rate) to keep with traffic. THREE (3) times it did not see the car in front of me and I had to apply the brakes to slow the vehicle down or I may have hit the vehicle in front of me. As mentioned above, this happened in very misty conditions. Every other car I have had would have automatically turned off the feature and given me an alarm bell to alert me that the adaptive cruise control had been disabled. This did NOT happen with my 2023 Subaru Solterra
