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

What stands out
Owners have filed 55 body complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
Among the 14 model years of Toyota Prius in our records for body problems, this one ranks #2 by owner-complaint volume.
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
The 2008 Prius body attracts two distinct categories of complaint.
The first—and by far the most common in this cluster—is progressive melting and degradation of the rear hatch release handle. Starting around year two or three, the rubber cover turns to a tacky, tar-like black goo that stains hands, hardens the hatch to open, and in advanced cases prevents it from opening at all. The material is sticky enough that forcing your fingers free can cause injury. Owners report this happens regardless of sun exposure (even garaged vehicles), most frequently in hot climates but not limited to them. The degraded material can short electrical circuits, draining the 12-volt battery and killing rear lights. Repair runs $197 to $540. Toyota has privately acknowledged this in Japan with free fixes but refuses to recall it in the US, dismissing complaints and claiming improper car washing caused it—a claim owners rightfully dispute.
The second category involves unintended acceleration paired with brake failure. Multiple owners report the engine suddenly roaring and accelerating hard while braking has no effect, sometimes making acceleration worse. These events occur during routine maneuvers and have totaled vehicles and struck other cars. One incident involved collisions with three vehicles at 40+ mph with the brake pedal unresponsive. A separate cluster of brake-failure reports shows ABS not engaging in wet weather and complete loss of stopping power leading to crashes.
Additionally, there are isolated reports of airbag non-deployment during collisions, a rear liftgate that drops unexpectedly while open, water intrusion into the trunk, and plastic fasteners failing on the latch assembly.

Failure modes owners describe
Rear hatch handle/latch cover deterioration and melting
Rubber or elastomeric cover on the exterior rear hatch release handle degrades and melts into a sticky, tar-like black gooey substance, making the hatch progressively harder to open and coating users' hands with black residue. Material becomes tacky and adhesive enough to require significant force to separate fingers. In some cases, the degraded material creates electrical short circuits affecting rear lights and battery drain. Advanced degradation can prevent hatch operation entirely.
When: Typically begins around 2–3 years of ownership; progresses over time. Appears in warm/hot climates and even in garaged vehicles.
Symptoms owners cite: Rubber cover softens and becomes sticky in warm weather; Black gooey, tar-like residue on hands after touching handle; Hatch becomes progressively harder to open; Handle droops or drips down over an inch; material falls off; In cold weather, hatch freezes and becomes stiff; Switch pressure plate fails to function; Rear light malfunction and battery drain from electrical short; Complete hatch-opening failure in advanced cases
Repairs/costs cited: Toyota sells entire wiring harness for $96 plus labor; replacement costs reported at $197–$540 depending on parts and dealer. Some owners report Toyota fixed it for free in Japan but not the US.
Recalls/TSBs owners mention: Toyota initially denied the issue; later acknowledged it in Japan with free repairs but has not issued a recall in the US. Toyota claims the failure may result from improper car-washing products, which owners dispute.
Unintended acceleration with brake failure
Vehicle accelerates rapidly on its own despite driver applying the brake pedal. Brake pedal becomes unresponsive or ineffective; brakes either fail to engage or make the vehicle accelerate faster. Incidents occur during normal driving and parking maneuvers. Car roars loudly and becomes difficult or impossible to steer at high speed. Multiple crashes result.
When: Incidents reported at 74,000 miles and during routine parking/deceleration; some drivers report multiple prior related incidents.
Symptoms owners cite: Engine roars loudly and vehicle accelerates rapidly without throttle input; Brake pedal pressed but vehicle accelerates or does not decelerate; Pumping or holding brake pedal has no effect; Noise is terrifying and vehicle becomes difficult to steer; Vehicle jumps or lurches forward when brake applied; Acceleration happens even with foot on brake only
Brake failure during normal driving
Brakes fail to engage or respond when driver applies pressure, resulting in collisions. In one case, ABS did not engage in wet conditions. In another, no skid marks suggest brakes were not applied or did not function. Brake failure occurs during traffic deceleration and parking situations.
When: Incidents at relatively low speeds (5–7 mph, 35–40 mph) and during wet/rainy conditions; one incident at 67,500 miles with regularly serviced vehicle.
Symptoms owners cite: Brake pedal does not engage or has no effect; ABS fails to engage in wet conditions; No skid marks visible after collision; Vehicle continues to move forward despite brake application
Airbag failure to deploy
Airbags fail to deploy in at least two collision incidents, resulting in head injuries to driver. One collision was rear-end; another was frontal impact at an intersection.
When: During collisions (one rear-end 7/31/2015; one frontal at intersection).
Symptoms owners cite: Airbag does not deploy during frontal collision; Driver head strikes steering wheel; Rear-end collision occurs with no airbag deployment
Water leak in rear trunk area
Water leaks into trunk spare-tire wheel well during rainy weather, creating potential for battery hazard and rust damage.
When: 40,000 miles; during rainy conditions.
Symptoms owners cite: Water accumulation in spare tire wheel well; Leak occurs during rain
Rear liftgate drops or fails to stay open
Hatch latch mechanism fails to hold the liftgate in an open position, causing it to drop suddenly. In one case, the latch dropped multiple times while the owner was removing groceries, striking the owner's head.
When: Timing not specified in narrative.
Symptoms owners cite: Liftgate drops suddenly when in open position; Latch fails to hold hatch open; Hatch strikes occupant
Plastic fasteners deteriorate on rear latch assembly
Plastic bolts or fasteners holding the rear latch assembly in place disintegrate over time, causing the assembly to crack and come loose.
When: Over extended time period.
Symptoms owners cite: Plastic fasteners disintegrate; Latch assembly becomes loose; Assembly cracks when latch handle is pulled
