NHTSA lists 4 safety recalls and 6 owner complaints for the 2023 Toyota Prius Prime. Most complaints involve electrical system (3) and power train (2). The EPA rates it 48–52 mpg combined, and NHTSA gives it 5 stars overall.
Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2023-2024 Prius Prime, 2023-2026 Prius, and 2025-2026 Prius Plug-in Hybrid vehicles. Water may enter the rear door switch and cause a short circuit, allowing an unlocked rear door to open unexpectedly.
Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2022-2026 Toyota, Lexus, and Subaru Solterra vehicles equipped with a Panoramic View Monitor (PVM) system. Please see the recall report for a complete list of models. A software error may cause the rearview camera to freeze or display a blank screen when the vehicle is in reverse. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 111, "Rear Visibility."
Gulf States Toyota, Inc. (GST) is recalling certain Toyota 2023 GR Supra, 2024 4 Runner, Corolla, Grand Highlander, Grand Highlander Hybrid, Land Cruiser Hybrid, Tacoma, Tacoma Hybrid, 2023-2024 BZ4X, Corolla Cross Hybrid, GR Corolla, GR86, Highlander, Highlander Hybrid, Prius, Prius Prime, Sequoia Hybrid, Tundra, Tundra Hybrid, Venza Hybrid, 2023-2025 Crown, and 2025 Camry Hybrid vehicles equipped with GST accessories. The load carrying capacity modification label may display inaccurate added weight values. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 110, "Tire Selection and Rims."
Complaints are unverified owner reports to NHTSA and are not normalized for sales volume. One complaint can cite several components.
“The vehicle exhibits an unaddressed factory programming defect where the Plug-In Charge Control ECU fails to enter sleep mode while plugged in or resting. This causes continuous, heavy parasitic drain on the 12V auxiliary battery, causing chronic low-voltage state across critical systems. The 12V auxiliary network supplies power to the primary control units, CAN-bus communication modules, and dynamic stability systems. Operating under chronic low-voltage causes system instability, erratic sensor processing, voltage brownouts, and rapid degradation of the 12V battery. In severe traffic or isolated operations, a depleted 12V battery creates a distinct safety hazard, including sudden loss of propulsion control, electrical failure, and stranded conditions. Toyota acknowledged this software logic flaw internally under Technical Service Bulletin T-SB-0054-24. However, because Toyota classifies this defect as a TSB rather than a mandatory safety recall, owners are left vulnerable to unexpected low-voltage electrical failures on public roads and are forced to pay out-of-pocket for an ECU reflash to repair a pre-existing manufacturing defect. This issue requires a…”
“My 2023 Prius Prime cannot be charged normally in hot weather without triggering a thermal-protection fault on its high-voltage charging system. Avondale Toyota diagnosed it in writing: "CODE P1CE996 CHARGER COOLING FAN REVOLUTION SENSOR COMPONENT INTERNAL FAILURE. THE ELECTRIC CHARGER ASSEMBLY HAS A INTERNAL OPEN CIRCUIT CAUSING IT TO BE INOP. RECOMMEND REPLACEMENT ADD PN# G9090-47061." Quote: $2,516.99 plus ~$200 diagnostic. The vehicle cannot verify its high-voltage charger's cooling fan is operating. In Phoenix heat (100F+), normal charging repeatedly sets the fault and check engine light. I verified by controlled testing: reduced-current charging in cool hours avoids the fault, but any normal charge in heat triggers it — in factory configuration, no obstruction. I am forced to restrict charging to nighttime reduced-current sessions to avoid operating the charger with unverified cooling. A plug-in vehicle that cannot safely complete a normal charge in summer conditions is a safety concern. This is a documented defect: Toyota TSB T-SB-0054-23 (8/7/23), "MIL ON With DTC P1CE996," states the charger assembly "has been modified to reduce the possibility of this…”
“The 2023 Toyota Prius Prime features fixed, non-adjustable rear suspension geometry. My vehicle arrived from the factory with the Right Rear Camber out of specification (-2.2°, max spec limit is -2.0°). Because the rear camber is non-adjustable and cannot be corrected, it caused rapid, unseen inner tread wear down to the steel cords by 20,000 miles, creating a severe tire blowout risk. Authorized Toyota dealership Ourisman Fairfax Toyota inspected the vehicle under RO #6195543/1 and verified that the camber is out of spec and that there is NO external physical damage to the suspension. Toyota Corporate closed my case and refused to address or reimburse the defect under the 3yr/36k Basic Warranty. I had opened a case with Toyota Brand Engagement Center (case number 260827002489) and they had denied any sort of responsibility.”
