Acid rain results from rainwater or other airborne moisture that become acidic due to industrial chemical impurities in the atmosphere. If these acidic compounds settle on an exposed vehicle, especially the horizontal areas such as the hood, roof, and decklid, significant damage to the painted surfaces can occur. Acid rain damage can typically be identified on vehicles by the presence of stains on the paint surface that resemble hard water spots. Unlike water spots however, acid rain damage cannot be removed by regular washing procedures. Also, because acid rain can etch and soften the paint, normal buffing or polishing repair procedures should not be attempted. This can cause further damage

Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering body on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
To prevent brake rotor rust from forming during transportation and storage, wheel film will be used instead of a cardboard type of anti-rust cover. The purpose of the wheel film is to shield the disc brake rotor from weather elements and initial rust before the vehicle is delivered to the customer. Consequently, the film should remain on the wheel for as long as possible.
full bulletin at NHTSA ↗The condition known as acid rain is caused by airborne chemicals or particles in the atmosphere, which mix with rainwater, nighttime dew, or high humidity to form acidic compounds. If these contaminants settle and remain on a painted vehicle surface, especially the horizonal areas of the hood, roof, and decklid, significant damage can occur. This damage is the result of actual etching of the paint and appears as pitting or water spots. As acid rain droplets on the vehicle surface evaporate, the concentration strength of the acid increases, causing deeper and more rapid damage. This evaporation and corrosive action also occur more rapidly on dark colored cars as direct sun heat increases. It
full bulletin at NHTSA ↗Toyota vehicles are currently protected with RapgardTM protective film designed to protect the horizontal painted surfaces. This material protects from acid rain, environmental fallout, and rail contamination. Follow the Removal Procedure in this bulletin to remove the RapgardTM protective film within 90 days from initial application.
full bulletin at NHTSA ↗Vehicles may occasionally be subjected to contamination by airborne iron particles shed from railroad tracks, train wheels, exposure to heavy machinery facilities, grinding, welding, etc. This type of contamination can be identified by the presence of small, red or brown particles on the paint surface. These particles are often difficult to see on dark color paints but can be easily felt when brushing a hand across horizontal body surfaces such as the hood, roof, or deck lid. Follow the Repair Procedure in this bulletin to clean vehicles that may have been subjected to contamination by airborne iron particles such as rail dust during rail transportation or extended storage near industrial ar

The failure pattern owners describe
Owners report windshields that crack and spread abnormally fast. Small rock impacts that would be routine on other cars cause star-pattern cracks that expand to cover the entire windshield within hours or days. Some cracks appeared with no impact at all—one in a covered garage, another triggered just by lifting the windshield wipers. One owner had three major cracks in less than a year of lease. Toyota dealers refuse warranty coverage, citing rock-damage exclusions, and windshield backorders prevent aftermarket replacement. Repair bills run $1,265 or more per replacement.
Blue and black paint is peeling across sun-exposed surfaces: roofs, trunks, doors, and rear quarter panels. Clearcoat separates from black trim near rear windows. One owner documented that the peeling began in 2019 and spread to all blue paint while a 2014 Prius in identical conditions shows no damage. Dealership and independent inspections confirmed the failure. Other 2016 Prius owners reportedly had paint recalls, but affected vehicles remain unaddressed.
One owner reports persistent clicking from the steering section underneath the car since 2018—unresolved—and expresses concern it signals a safety issue. Another documents a front bumper crushed by road debris. No manufacturer response or technical bulletins are mentioned in any narrative.
Failure modes owners describe
Windshield premature cracking and rapid crack propagation
Multiple owners report windshield cracks that develop unexpectedly or spread rapidly after minor impact, even from small rocks or pebbles. Several cracks occurred in protective settings (covered garage, after lifting wipers) with minimal or no discernible cause. Owners report the glass appears unusually brittle or stress-prone. One owner experienced three major cracks within a year of lease; another had two replacements in 2018. Cracks frequently spread from edge or base to cover large areas within hours or days.
When: Incidents reported from 2018 onward; one owner had 17k miles when issue occurred; instances include minor road debris, lifted windshield wipers, or unknown cause in protected parking
Symptoms owners cite: Star-pattern cracks from small rock impacts; Cracks spreading rapidly after minor impact or no visible impact; Cracks developing from windshield base and edges; Cracks appearing after windshield wiper manipulation; Spontaneous cracking in covered garage with no impact detected; Multiple cracks on single vehicle within short timeframe
Repairs/costs cited: Replacement windshield cost cited at $1265 by Toyota dealer; backorder issues reported; Toyota warranty does not cover rock damage; aftermarket production unavailable per owner reports
Recalls/TSBs owners mention: Toyota dealer declined warranty coverage citing rock damage exclusion; backorder on replacement windshield noted; no TSB or recall mentioned for windshield defect
Exterior paint peeling and clearcoat failure
Blue and black exterior paint showing widespread peeling, particularly in areas exposed to sun: roof, trunk, door panels, and rear quarter panels. Damage includes clearcoat separation on black trim pieces. One owner noted damage began in 2019 and spread across all blue paint areas despite exposure conditions matching a non-affected 2014 red Prius. Paint appears to be failing prematurely from sealant or protective layer breakdown. One owner mentions other 2016 Prius have had paint recalls. Dealership and third-party inspections confirmed paint problem and potential corrosion risk.
When: Damage began appearing 2019 and onward; documented on vehicles within first few years of ownership
Symptoms owners cite: Black panel peeling behind rear mirror; Blue paint showing damaged spots on roof, trunk, door panels; Clearcoat peeling from black trim pieces near rear windows; Paint damage concentrated in sun-exposed areas; Pattern affecting all blue paint on vehicle
Repairs/costs cited: No repair costs cited; dealership and independent shop inspections confirmed problem; corrosion risk noted if protective qualities compromised
Recalls/TSBs owners mention: Other 2016 Prius models reportedly subject to paint recall; complainant requests inclusion; no response documented for this vehicle
Clicking or noise from undercarriage/steering area
Owner reports persistent clicking sounds from underneath the vehicle, particularly from the steering section. Began in 2018 and has not been resolved. Owner expresses safety concern, questioning whether steering mechanisms are functioning properly. Owner chose to drive a 2012 Prius instead on highway to feel safer. Despite NHTSA complaint filed, issue reportedly not addressed.
When: Reported starting 2018; ongoing at time of complaint
Symptoms owners cite: Clicking sounds from underneath car; Noise appears to originate from steering section
