2018 Toyota Tacoma — Known Issues & Recalls

Your brake booster has failed and brake fluid is leaking inside your cab, causing you to need excessive brake pedal pressure to stop. Your independent service center has confirmed the issue, and you've noticed oil stains on your floor mats. Because your brakes could fail completely, this is a serious safety concern that will likely require replacement of the brake master cylinder and brake booster assembly.

Your brake actuator assembly is leaking brake fluid, which drips onto the brake lever and floorboard. A Toyota dealership has confirmed this is happening on your vehicle. This is a known safety issue that Toyota has issued a recall for (Safety Recall J06). The fix will involve replacing the brake actuator assembly.

Your brake master cylinder seal has failed, causing brake fluid to leak onto the floorboard near your brake pedal. This is a serious safety issue since brake fluid loss can reduce your braking ability. The master cylinder will need to be replaced or rebuilt to stop the leak and restore proper brake function.

Your 2018 Toyota Tacoma is leaking brake fluid from inside the cabin above the brake pedal. An independent mechanic traced the leak to the brake booster and master cylinder, which are the same components involved in a known recall (NHTSA Campaign 18V888000), but your vehicle's VIN wasn't included in that recall. Although no warning lights are on and the leak is small now, it may worsen over time.

Your truck suddenly lost power while driving on the highway at 70 mph, forcing you to exit and nearly causing an accident. The engine warning light came on and the truck stalled; when restarted, it had limited power. A repair shop diagnosed low fuel pressure (14 psi) and recommended replacing the low-pressure fuel pump, but the Toyota dealership refused to cover it under recall, claiming the recall was already performed in 2020 and that they couldn't replicate the low-pressure reading. Fixing this issue will require diagnosis and likely replacement of the fuel pump assembly.

Your truck has a strong fuel smell inside the cab. This could indicate a fuel leak or issue with the fuel system that needs to be inspected. A mechanic should check the fuel tank, fuel lines, and connections to locate and repair the source of the leak.

Your vehicle won't start and the 4x4 system isn't working. Your husband suspects the fuel pump has stopped working based on his troubleshooting, though no check engine light appeared before the problem started. The vehicle was running fine the evening before but suddenly stopped. A failed fuel pump while driving could have been dangerous, so the repair will likely involve replacing the fuel pump.

Your truck won't start. A diagnostic scan confirmed the fuel pump has failed and is preventing the engine from running. The fuel pump will need to be replaced to restore normal operation.

You discovered that your 2018 Toyota Tacoma's mileage was misrepresented at the time of purchase. The odometer showed 32,000 miles when you bought it, but your Carfax report later revealed the vehicle actually had over 200,000 miles. Additionally, the seller was not the actual title holder. You may need to consult with a lawyer or your state's consumer protection agency about potential odometer fraud and title issues.

You purchased a 2018 Toyota Tacoma that showed 57,000 miles at the time of purchase, but when you went to register it, you discovered the actual mileage was 254,000 miles — a significant discrepancy suggesting the odometer may have been tampered with or rolled back. This is odometer fraud, which is illegal. You may need to contact law enforcement and your state's motor vehicle department, and consider consulting an attorney about your purchase.

Your brake master cylinder is leaking fluid into the cabin behind the brake pedal, and brake fluid has gotten into the wiring harness connected to the brake switch. Brake fluid leaking onto electrical components is a known fire hazard. This will likely require replacing the master cylinder and inspecting the wiring harness for damage.

Your vehicle's vacuum pump is not working properly, which means your power steering assist for the brakes may fail. Without power assist, your brakes will be much harder to apply and could become unsafe to drive. The repair will likely involve inspecting and replacing the vacuum pump to restore power to your brake system.

You're hearing a ticking noise coming from your engine that gets louder as you accelerate. This could indicate several engine issues that should be inspected soon to prevent further damage.

Water is leaking into your truck's cabin through the two rear vents, which aren't sealed properly to the body. The water runs down the interior walls and onto the floor, soaking the carpet and padding and causing mold growth throughout the cab—and even leaking through floor grommets to cause rust on structural cab mount bolts. This creates both a health hazard from mold exposure and a safety concern if the rusted bolts are compromised in an accident. Fixing this will likely require Toyota to properly seal or redesign the rear vents and address any rust damage to the structural components.

Your power steering system stopped working properly while driving, making it much harder to steer your Tacoma. A mechanic found that the rack and pinion — the component that converts steering wheel movement into tire movement — had failed. Replacing the rack and pinion assembly will be needed to restore normal steering function.

Your truck's hood and roof paint has started turning white and fading after a couple of years, even though you've only driven it on streets. Additionally, after 4 years of ownership, your suspension components have started making loud noises, despite normal street driving with no off-road use.

Your third brake light (mounted on the cab) is leaking water inside your vehicle, which is causing a wet, musty smell and potential mold growth along with staining. This moisture intrusion needs to be addressed to prevent further interior damage and mold issues. The fix likely involves resealing or replacing the brake light assembly and checking the weatherstripping around it.

Your truck's clear coat is peeling or worn away, exposing the base coat paint underneath. This leaves the metal body panels vulnerable to rust and corrosion over time. You may notice dull spots, oxidation, or paint damage on the exterior. Fixing this typically involves sanding, repainting, and applying a new clear coat to protect the base color.

Your vehicle's service brakes, fuel/propulsion system, and forward collision avoidance system were inspected by Toyota and repaired. You're filing this complaint to document the issue even though the manufacturer has already fixed it.

Your 2018 Toyota Tacoma's clear coat is peeling off the roof and doors, which is allowing the underlying paint to deteriorate and get damaged. This is a factory paint defect affecting the Cement Grey color on your vehicle. Fixing this typically requires having the affected areas stripped and repainted with new clear coat protection.
