The 2026 Toyota Prius illuminates a road distance on an unlight, rural road of 110 feet on low beam. Parked at the beginning of one white dashed center line, the low beams illuminate two additional white dashed lines. Road lines are a standard 12 ft painted line with a 37 ft interval between lines for a total of 110ft of illuminated road. The average stopping distance of the Toyota Prius traveling at 55mph is ~260 feet. I am able to see less than half the stopping distance of the vehicle. I have hit a deer twice because of the lack of road illumination. Each deer strike was with with two separate 2026 Toyota Prius vehicles. Both vehicles had the same illumination pattern. Fortunately, it was a deer strike, however, imagine for a moment if it were a human walking along the the road or a disabled vehicle. This is a safety concern and does not meet the NHTSA regulation FMVSS N. 108, summarized below. National Highway Traffic Safety Administration (NHTSA) regulations under FMVSS No. 108 mandate that low-beam headlights provide sufficient, controlled illumination for night driving while preventing excessive glare, generally aiming to illuminate approximately 200–300 feet ahead. I did complain to Maplewood Toyota about the issue and the Service Team stated they can only adjust the headlight within the Manufacturer's suggested range. This vehicle was purchased as a new, I made an assumption that everything would be properly adjusted coming off the manufacturing floor. Maplewood Toyota did not complete an inspection of the vehicle to determine "as found" headlight aiming prior to the deer strike. There were no warning lamps, messages or other symptoms related to this incident. Jeff Rabinort, Service Manager had a conversation with me following the incident. He did confirm there was a maximum adjustment that they could make to the headlight, but was unclear what that was. I encouraged Jeff to drive a 2026 Toyota Prius on an rural road for confirmation.

A 2026 Toyota Prius was delivered to me on or about February 5, 2026 while subject to an active federal safety recall involving a rear door electrical switch defect. The recall indicates that water intrusion into the rear door switch can cause an electrical short circuit which may allow a rear door to open while the vehicle is in motion. At the time of delivery, there was no remedy available for this recall. The recall had been announced on January 28, 2026 and was active in both the manufacturer’s system and NHTSA recall lookup at the time the vehicle was leased. Despite the active recall and lack of remedy, the vehicle was delivered for use. The safety risk is that a rear door could open unexpectedly while driving, potentially creating risk of passenger ejection or injury to other motorists. No failure has yet occurred, but the vehicle was delivered under active recall without repair. This complaint concerns delivery of a new vehicle while subject to an unrepaired federal safety recall.

The two outside rear view mirrors on the 2026 Prius have an adjustment problem. When attempting to adjust them they will freeze (won't move), move intermittently, and jerk. The Toyota dealer told me that it is a known problem and all 2026 Priuses have the same problem. He further informed me that Toyota is aware of the problem. He went to another new Prius on the dealership lot and found that its outside rear view mirrors do the very same thing. This is a serious safety issue and the manufacturer should address and remedy it. Toyota nor the dealership have a fix for this problem.

2026 model year Toyota vehicles are equipped with driver side floor mat retainers to secure the floor mat in the correct position. In addition, some models may also utilize retainers for passenger side and rear seat floor mats. During Pre-Delivery Service (PDS), follow the appropriate Installation Procedure to attach the driver side, and if applicable, the passenger side and rear seatfloor mats to the vehicle carpet using the floor mat retainers.

During the manufacturing process, tires are mounted on the vehicle as matched sets to help reduce conditions such as pulling or drifting. If the wheels are replaced or refinished before vehicle delivery, it is important that the tires remain on the vehicle in the same location and in the same direction of rotation.

Long-term or off-site storage requires special care to maintain vehicle condition. The following guidelines should be performed to minimize vehicle component/part degradation due to extendedvehicle storage conditions. Long-term storage can affect a vehicle’s systems and components. Any problems that are found should be corrected immediately.

A battery in a stored vehicle is subject to conditions that can reduce its performance and service life. These conditions include storage period, temperature, parasitic drain, and battery load. Because of these factors, battery inspection and maintenance are required in order to ensure proper operation and optimal battery life.

Pre-Delivery Service (PDS) is a critical step in satisfying our new car customers. Customer feedback indicates the following areas deserve special attention when performing PDS: • Careful inspection for paint chips/scratches and body dents/dings. • Proper operation of electrical accessories (including interior light, clock, and radio reset). • Interior cleanliness. • Proper function of mechanical systems. The PDS process helps identify potential vehicle concerns before customer delivery. After completing the PDS process, maintain accurate PDS records by ensuring the required documents listed below are completed and recorded in accordance with Toyota Warranty Policy. • GTS+ Health Check • Completed PDS Check Sheet • Battery Charge Test Print Out • GTS+ Tire Pressure Information Customer retention and proper maintenance of vehicles are and have always been a major focus for Toyota. To help remind customers that regular service is essential to the proper maintenance of the vehicle, dealers are required to install a service reminder sticker before delivery. By doing this, customers will be reminded to return to your dealership for service. Your current service reminder sticker may be used. This bulletin contains the PDS procedures that apply specifically to 2026 model year Prius and Prius PHV vehicles.
