ENGINE,FUEL/PROPULSION SYSTEM — Filed 05/01/2026

2018 Toyota Tacoma SR 4WD Double Cab, 3.5L V6 (2GR-FKS). At about 87,000 miles the check engine light came on with code P11EC, Cylinder 1 Air-Fuel Ratio Imbalance (Port). Cylinder 1 failed compression. Leakdown and coolant tests had passed earlier; borescope did not show heavy scoring. The Toyota dealer said replacing the direct injectors would fix compression (quote about $4,499). After the dealer injector repair, cylinder 1 was still 124 psi (spec about 142-180 psi), so it did not fix compression. The dealer then quoted $11,778 for a short block (+$500 incidentals) and $14,238 for an engine assembly that was not new (about 45,000 miles on the replacement discussed); adding injectors again put the short-block path at about $16,278. I was steered toward buying a new truck and had the injector work reversed because it did not fix what they said it would. Toyota Brand Engagement Center reviewed the case, called the dealer, took VINs for other Toyotas, and denied goodwill; no recall or TSB. An independent shop later pulled the engine and found the cylinder 1 exhaust valves leaking badly; cylinder wall still looked good. Machine shop valve job, new rings, injectors tested (two bad), all six replaced; repair about $8,000. Truck runs normally after. Consequences: loss of power, failed emissions monitors, risk of further engine damage if driven, high repair cost. Not a crash. This appears to be a known pattern on the 2GR-FKS in 2016-2019 Tacomas (P11EC, cylinder 1, leaking/burnt exhaust valves, often after direct-injector washdown). Toyota has not recalled; dealers stop at injectors or quote a short block/used engine, and owners pay out of warranty. Please log this under 2018 Toyota Tacoma: engine, fuel system, and valve train (cylinder head/exhaust valves, fuel injectors), so the pattern is on record. Servicing dealer: Nashville Toyota North. Toyota Brand Engagement case 260521000967.

I have a clear coat bubbling issue on my mirrors and also multiple clear coat stains on the hood that just developed on my Toyota Tacoma Off Road-Inferno Orange paint after two years that I own it. I called Toyota, there is no recall on my paint color, but I've viewed an online post someone has placed a lawsuit for the same reasons, but a different color. They've had a recall on white paint but not my color and I wanted to document the complaint. I called Toyota corporate and they said to file it with NTSB.

I own a 2018 Toyota Tacoma SR, manufactured 11/2017, with factory paint code 1G3 Magnetic Gray Metallic. The factory clear coat is experiencing extensive delamination/failure on the hood and roof. This isn't isolated stone damage or normal cosmetic wear. The clear coat is failing extensively across the horizontal panels. I'm aware Toyota has previously acknowledged clear-coat peeling on Tacoma vehicles through T-SB-0004-20 and Customer Support Program 20TE02, and that there are documented complaints involving 2018 Tacomas experiencing clear-coat failure on the hood and roof. I understand my VIN may not currently fall within those programs, but I'm requesting that Toyota inspect and document the condition and consider goodwill assistance toward repainting the affected factory-painted panels. I'd also like a Toyota case number assigned to the paint failure.

Vehicle hits a bump in the road and the check engine light comes on, followed by the gas pedal being non-responsive and an error code on the instrument panel saying “Brake Override System Malfunction. Check with dealer.” and “Pre-collision System Malfunction. Visit your dealer. ” When this occurs, have to coast the vehicle to a safe place, turn off and wiggle the Radar Control piece attached to the front grill sometimes multiple times before the truck will clear the code and accelerate. Been an ongoing issue for several months. Have replaced the front grill sensor and plate and the issue persists.

The cab vents failed causing water to soak the carpet and pad from the back wall to the front of the cab. Mold was growing through out the the cab. Carpet & pad had to be removed. This is a known problem by dealerships and owners of Toyota Tacoma. Because the water was under the seats, trim and weather mats it went undetected exposing us to mold. Problem was reported to Toyota dealership and Toyota Corporation. A case was logged 07/10/2026 as Case # 260710001840. The resolution offered was ordering and replacing parts. All parts required for repair and on backorder. Hundreds of orders for these parts in their system. Carpet and under mat had been replaced 05/02/2025 due to a Toyota recall campaign 21TD03.

WHAT FAILED: The clear coat finish on the exterior paint of my 2018 Toyota Tacoma has failed (cracking) in two separate locations on the same vehicle, indicating a manufacturing defect rather than normal wear. In late 2024, I discovered clear coat cracking on the roof and hood. I reported this to Toyota (Toyota case #241028000714) and paid approximately $2,000 out of pocket to have an independent body shop repaint the affected panels, as Toyota corporate declined to assist after the repair had already been performed. The clear coat is now cracking again at approximately 48,925 miles, this time on the cab in the pillar/trim area between the tops of the doors and the roofline. The vehicle and affected areas are available for inspection upon request. SAFETY IMPACT: This is a cosmetic exterior paint/clear coat defect. I have not identified any impact on vehicle operation, structural integrity, or visibility, and I am not aware of any safety risk to myself or others resulting from this issue to date. I am reporting it to document a recurring defect pattern on this vehicle. REPRODUCED/CONFIRMED BY A DEALER OR SERVICE CENTER: The 2024 occurrence was inspected and repaired by an independent body shop (not a Toyota dealer). The current occurrence has been reported to Toyota corporate (Toyota Brand Engagement Center) along with photographs, but has not been physically inspected by a Toyota dealer. INSPECTED BY MANUFACTURER, POLICE, OR INSURANCE: Toyota corporate reviewed photographic evidence of the current issue through my correspondence with the Toyota Brand Engagement Center, which I have asked to be linked to prior case #241028000714. Toyota has not physically inspected the vehicle. This is not a crash-related issue, so no police or insurance inspection has occurred. WARNING LAMPS OR PRIOR SYMPTOMS: Not applicable. This is a cosmetic paint/clear coat defect rather than a mechanical or electronic system issue, so there were no dashboard warning lamps or system messages

The cabin pressure vents, located at the rear of the cab below the rear window on the body frame have failed. The seal on the exterior of the vents has dry rotted. This has caused an extensive amount of water intrusion that is undetectable until it has been present long enough to cause mildew issues. Being that water enters below the vehicle carpet and padding you cannot see it, your first warning sign is smell. When I began to assess the issue I pulled up my carpet to find standing water and mold. This is supposed to be a safe environment where I can transport myself and my family and I now I have to be concerned about mold inhalation each time my toddler sits in my truck. Toyota needs to do an immediate recall to the cabin vents and replace them with a product that can actually with stand the elements. Additionally they need to replace all the carpet, twill, and padding that has been compromised.

The contact owns a 2018 Toyota Tacoma. The contact stated that while the vehicle was parked, there was an abnormal odor coming from the inside of the vehicle. While the vehicle was being serviced, the dealer discovered that the inner padding on the front passenger side, the rear passenger side, and the rear driver side was soaked with water, and due to the water accumulation, there was mold forming on the floor. The contact had placed towels to soak up the water while driving; however, the contact later discovered that the mold had spread to the towels as well. No warning lights were illuminated. The dealer diagnosed the vehicle and stated that the rear cabin pressure bin needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure.

STEERING — Filed 05/18/2026

am filing this complaint regarding a power steering rack leak on my [2018] Toyota Tacoma with [83,000] miles, which I purchased used three months ago from Fred Anderson Toyota of Greer in South Carolina. The dealer represented the vehicle as having passed a 160-point inspection and implied CPO-level standards, but it was not actually Certified Pre-Owned. The steering rack is now leaking power steering fluid, with visible accumulation in the boots, despite stable fluid levels in the reservoir during my ownership. This issue appeared very shortly after purchase, raising concerns that it was a pre-existing defect. Power steering leaks can lead to loss of assist and increase crash risk if they worsen. I request that NHTSA investigate whether this represents a safety defect affecting Toyota Tacomas, as similar complaints appear common in owner forums

ENGINE — Filed 02/01/2026

The engine in my 2018 Toyota Tacoma failed at 39000 miles and Toyota is refusing to cover the repair costs. I have records of all regularly scheduled maintenance performed and I have never done anything that would put additional stress on the engine such as off-roading or towing. This engine is defective and should be recalled. There are numerous reports online of the same issue.

The Break booster has failed or started since the break fluid is leaking inside the cab. And other trucks from the same year as my truck did have a recall for the break master cylinder failing. My breaks could potentially go out fully and I wont be able to stop. My problem has been confirmed by my independent service center. And also there's alot of other people having the same issue online. Since the floor mats show oil stains just like how I found out I was having a issue.It hasn't been confirmed by the manufacturer but I will be taking it soon to be inspection but since a recurring issue with multiple trucks online. I wanted to report it here so the recall could be extended to other trucks from same recall year. I noticed i was having a problem when I had to press down the breaks really hard to come to a stop. Then thats when I stopped and saw the oil on the floor mats. And my truck has really low mileage for the year and its safety concern to me and being that the replacement is really expensive just the part is around 1200.

Pulling vehicle into the garage on a cold morning (15 deg F). Hydraulic booster/brake master cylinder suddenly stopped providing boost pressure and brake pedal dropped to the floor. With no braking effort able to be applied the vehicle was driven into the house at slow speed. No hydraulic leaks are noted and pedal height and brake performance seems to have returned. There is fluid in the master cylinder reservoir and it doesn't appear to be contaminated. Braking capability returned after placing the vehicle in park and then reversing. Waiting for insurance follow up to select a collision repair shop and have the vehicle towed for repair. Dash cam video of the incident is available and clearly shows braking occurring and then the vehicle speeding up or failing to stop. Was unable to upload the video due to size. Photos are also available showing the damage and dry garage floors where the accident occurred. Vehicle is equipped with WeatherTech floor mats and I've verified there are no issues with mats and unattended acceleration with photographic documentation. I was the driver during the incident, am ASE Master Certified, and have taught automotive courses at the local community college for the last 12 years, worked as an automotive technician for 10 years prior, and work professionally as a Mechanical Engineer. Leveraging my experience, there is clearly a present concern with the hydraulic brake booster/master cylinder, particularly at cold temperatures.

THE CAR WAS PUT IN REVERSE IN ORDER TO GET OUT OF A PARKING SPACE. AS I TURNED THE WHEEL AS IT WAS IN REVERSE THE CAR BEGAN TO ACT WEIRD AND THE BRAKES DID NOT SEEM TO WORK. I PUMPED THE BRAKES 3 TIMES, BUT IT WAS TOO LATE AND THE CAR PARKED BEHIND ME WAS HIT. I WAS GOING SLOW WHEN I REVERSED, HOWEVER MY WHOLE BUMPER SNAPPED OFF AND MY TAILLIGHT SHATTERED. THE TRUCK SEEMED TO HAVE ACCELERATED WITHOUT THE GAS PEDAL BEING USED....THE BRAKES SEEMED TO WORK JUST FINE AFTER, HOWEVER DEALERSHIP TOLD ME THERE WEREN'T ANY CODES INDICATING A LOSS OF BRAKES. THERE WAS NO FLUID OR LEAKAGE ON THE COMPARTMENT EITHER. EVERYTHING WAS FINE I WAS TOLD, BUT IT DOESN'T SEEM TO ADD UP FOR ME. THIS TRUCK WAS SECOND-HAND FROM THE DEALERSHIP, SO I AM NOT SURE IF IT WAS PART OF THE TRUCKS THAT HAD A RECALL ON BRAKES. THE CURRENT RECALL ON IT HAD TO DO WITH THE PUMP WHICH THERE IS NO REMEDY FOR.
