Toyota GR86 Common Problems

ENGINE

Owners report issues with the 2022 Toyota GR86's engine, primarily related to oil starvation and excessive RTV silicone in the oil system. Complaints frequently mention catastrophic engine failure occurring without warning lights, often due to clogged oil lines from excess RTV, with some cases resulting in engine fires. Typical symptoms include sudden engine shutdowns and, in one instance, a fire that led to an injury. These problems are noted at various mileages, with some failures occurring as early as 6,700 miles. Safety implications include loss of power steering and brake assist, and the risk of fire, which are critical considerations for potential buyers.

EXTERIOR LIGHTING

Owners of the 2022 Toyota GR86 report two primary issues with exterior lighting. The most common complaint involves the rear turn signals failing to illuminate when the rear of the vehicle is directly exposed to low-angle sunlight, such as during sunrise or sunset. This results in hyperflashing on the dashboard and front signals, but no illumination from the rear signals, potentially leading to safety risks during lane changes or turns. Another issue involves the driver-side dome light failing, particularly after the vehicle sits in the sun, though this is less frequently mentioned. Complaints do not specify mileage or timeline patterns, but the safety implications of non-functioning rear turn signals are noted by multiple owners.

ENGINE

Owners of the 2023 Toyota GR86 report issues related to spark plugs and engine seals. Complaints frequently mention premature failure of spark plugs, leading to misfires and drivability loss, with some reports indicating a need for extensive repairs including engine replacement. Oil leaks from spark tube seals are also noted, with potential fire hazards due to oil exposure on hot engine parts. One owner describes a high-speed stall and subsequent engine failure not covered under warranty, suggesting possible customer abuse. These issues typically arise at various mileages, with one report at approximately 33,000 miles, and pose safety risks such as loss of control and fire hazards.

FUEL/PROPULSION SYSTEM

Owners report that the 2023 Toyota GR86 experiences issues with fuel lines in the engine bay, specifically rubbing against the hood or other components. Complaints frequently mention visible wear marks and material removal on these fuel lines, which are located on both the driver and passenger sides. Symptoms include rubbing marks and wear on the fuel line's outer sleeve, with no immediate bursts reported, but with concerns about potential fire risks. Some owners refer to this issue as more prevalent in the second generation of the vehicle, noting that the first generation had protective sleeves on the fuel lines. There are no specific mileage ranges provided, but the repeated nature of these descriptions suggests the wear may occur early in the vehicle's lifespan.

UNKNOWN OR OTHER

Owners of the 2022 Toyota GR86 report issues related to excess RTV silicone in the oil pan, which can break off and potentially block the engine oil pickup tube, leading to oil starvation and possible engine failure. Complaints frequently mention the presence of silicone in the oil and reference engine problems that could arise from this condition. One owner specifies discovering this issue during an oil change and observing the problem as early as 1,000 miles. Additionally, another distinct issue involves the vehicle's blinker randomly ceasing to function, with one owner noting the problem began shortly after 200 miles and persisted despite dealership visits. While no crashes or loss of control are reported, these issues may affect vehicle reliability and maintenance needs.

FUEL/PROPULSION SYSTEM

Owners of the 2025 Toyota GR86 report issues with the fuel line rubbing under the hood. Complaints frequently mention this rubbing as a potential fire risk, with some owners noting awareness of similar issues among other GR86 vehicles. While specific mileage ranges are not detailed, the repeated mention of this problem suggests it may occur early in the vehicle's life. Safety implications are highlighted, with owners expressing concern about the possibility of a fire while operating the vehicle. These reports indicate a pattern that prospective buyers should consider, particularly in relation to the condition of the fuel lines.

FUEL/PROPULSION SYSTEM

Owners report issues with the fuel lines in the 2024 Toyota GR86, specifically noting wear and severe rubbing. Complaints frequently mention that the rubbing occurs under the hood, often against another fuel line, which results in the removal of printed writing and flattening of the hose. These issues are observed at around 6,000 miles, with one owner linking similar problems with related models like the 2023 Subaru BRZ. The potential for the rubbing to lead to a fuel line breach poses a risk of engine fires, highlighting a significant safety concern. This information is crucial for used car buyers considering the GR86, as it suggests a need for careful inspection of the fuel lines for signs of wear and rubbing.
