2023 Subaru Solterra 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.”

“I am writing to express my concern regarding a series of significant issues I’ve experienced with my vehicle, all occurring within a span of less than six months and well within the 3-year/36,000-mile warranty period. 1.Battery Failure in Cold Weather: After the first exposure to below-freezing temperatures, the vehicle would not start on multiple occasions. This ultimately led to a full battery replacement. 2.Suspension and Rear Motor Issue: I recently brought the vehicle in due to an increasingly poor ride quality and excessive road impact. The inspection revealed a suspension issue and, more seriously, a failing rear motor that now requires replacement. 3.Electrical Malfunction – Blinker Failure: The vehicle is currently in the shop due to the failure of the left turn signal, which was traced to erosion in the casing housing the electrical wiring. These repeated failures are deeply concerning, particularly for a relatively new vehicle. I am requesting a thorough review of the situation and a clear resolution path, as this level of reliability is unacceptable for a vehicle still under warranty”

“Sudden unintended acceleration while maneuvering to park. The acceleration was instantaneous and forceful, that in less than 20 feet of rapid movement the car forced itself over some utility poles laying behind the intended parking spot, and jumped from the utility poles, fast enough so that the first ground contact was nearly 10 feet beyond the poles (as evidenced by disturbed grass in the photos). Stopped stuck on hard debris, irregular terrain, and dead tree logs. In other circumstances, this could have had grave consequences to others or the driver. We're not sure we can trust this vehicle not to do this again. Not checked with a dealer. (All manufacturers blame drivers for sudden unintended acceleration.) The vehicle is being repaired at a body shop. Damage was to front and underside. There were no prior warnings or symptoms.”

“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.”

“Leased the vehicle in November 2023, the Air Condenser failed at the beginning of August, it no longer blows cold air. I have a 1year old baby, it’s California in the summer and it gets 105+ outside, in the car is even hotter. This is a safety hazard, my daughter can no longer be in the vehicle, and my wife is also pregnant driving it to work every day. The vehicle is still waiting to be repaired since August 4th when the issue was identified, and the date of August 12th since the manufacturer has identified the issue at their repair shop. The air condenser has not come in yet.”

“Driving vehicle during rain storm at 10mph through standing water approximately 1 foot depth while exiting freeway in San Francisco caused front bumper components to loosen/crack, front fender liners to tear off, thereby exposing the electrical components of the battery drive unit and electricals under the front hood, including high voltage cables to be exposed to water intrusion. We can see the bright orange high voltage cables through the wheel well, along with electrical wires that appear to be grounds! Safety concern of exposing electrical high voltage system to water if driver was not aware that fender liners detached while driving. We are concerned this may pose potential risk of electrical malfunction as car is driven on wet roads due to water intrusion, reaching sensitive parts, potentially causing sudden electrical or mechanical issues and affecting vehicle safety, causing sudden malfunction given electric vehicle.
