| May 2026 | STRUCTURE | The upper grille and hood trim assembly on my 2018 Toyota Tundra 1794 Edition failed and partially detached from the vehicle due to apparent mounting clip and retainer failure. The failed component is available for inspection upon request. Photographs of the damage and detached trim assembly have been documented. This failure created a significant safety risk because the panel could have fully detached while the vehicle was in motion and become a roadway hazard to other motorists. The detached component also created concerns regarding possible interference with the front grille assembly and Toyota Safety Sense components located behind the grille area. Prior to the failure, there were no warning lamps, dashboard messages, or other electronic warnings indicating a problem. There were also no visible signs of impact damage or collision that would explain the failure. The condition appears to have occurred during normal vehicle operation. The vehicle currently has approximately 76,900 miles. After researching the issue, I identified multiple reports from other Toyota Tundra owners describing similar failures involving the upper grille garnish, mounting tabs, and retaining clips on this generation of Tundra vehicles. At this time, the issue has not yet been formally inspected by Toyota, law enforcement, insurance representatives, or an independent repair facility. Dealer confirmation is currently UNKNOWN. However, based on visual inspection, the mounting clips and retainers appear to have failed under normal operating conditions. | Crash: No Fire: No | Unknown |

| Jan 2026 | ELECTRICAL SYSTEM,FUEL/PROPULSION SYSTEM,FORWARD COLLISION AVOIDANCE | When starting up my truck in the morning there is rough idle that cause truck to sputter and sound horrible. It eventually smooths out but I believe the computer needs flashing. When I look online some have a recall for the engine 3UR-FBE / 2018 Toyota tundra, but when I put in my vin # it shows no recall and throws off check engine light Code. Also my radar sensor that it on for cruise control is showing up on dash please contact dealer and flashing. They have replaced this before with recall and now it’s acting up again. Also traction control is lighting up I. The dash as well blinking along with all these codes. | Crash: No Fire: No | Unknown |
| Dec 2025 | FUEL/PROPULSION SYSTEM | The vehicle was having issues with the fuel pump which was a known safety recall for the 2018 Toyota Tundra vehicles. The service man said that when he pulled up the safety recall for our VIN number that it didn't show anything, but we needed a new fuel pump according to the service codes that were coming up after inspection. They made us pay for the fuel pump before we left the dealership. The vehicle was too dangerous to drive without having the work performed (getting stalled out or stuck on the highway) so we had to pay for the work. Toyota said that I could file a complaint with NHTSA to get my vehicle added to this recall and then try again for reimbursement. I have the repair paperwork if needed to support this claim. | Crash: No Fire: No | Unknown |
| Nov 2025 | SEATS | Heated seat element and module burnt | Crash: No Fire: No | Unknown |
| Nov 2025 | FUEL/PROPULSION SYSTEM | I had an independent service center diagnose the issue with my 2018 Toyota Tundra. My truck would not start so there was no safety concern, but if the fuel pump failed while driving then the safety concern rises. The electrical connection inside the fuel pump was melted. There was no warning signs of the issue, it just would not turn all the way over. I looked up that the 2018 Toyota Tundra w certain VIN #'s have a recall for the fuel pump, unfortunately my VIN # is not included. | Crash: No Fire: No | Unknown |

The contact stated that there was no warning light illuminated. The contact stated that the vehicle was towed to a local dealer. The dealer diagnosed the vehicle and determined that the fuel module needed to be replaced. The vehicle was repaired. The manufacturer was not informed of the failure. The contact researched online and related the failure to NHTSA Campaign Number: 20V012000 (Fuel System, Gasoline); however, the VIN was not included in the recall. The failure mileage was approximately 103,000. | Crash: No Fire: No Towed | 103,000 |

| Jul 2025 | FUEL/PROPULSION SYSTEM | My fuel pump died with symptoms consistent with other 2018-2020 Tundras involved in a fuel pump recall. | Crash: No Fire: No | Unknown |
| Apr 2025 | FUEL/PROPULSION SYSTEM | Fuel pump out after 3 weeks.4-24-25 Three weeks ago 4-07-25 I had an issue with my fuel pump and the Toyota dealer replaced it. I also reported it here at that time. I typed up what the truck did and sent it to y'all before i ever got word of what was wrong. The report from them is not accurate. They stated I had run out of gas and the fuel pump was burnt up. As I stated I lost propulsion but the truck was still running. I will say I also know I had a couple of gallons of gas in it as I added some the day before and I know how far I drove as I put a little extra over the distance I was going and of course it had gas in it since I drove it to the gas station. Anyways they replaced the pump and now 3 weeks later 4-24-25 the new pump is out. The truck acted the same as it did 3 weeks ago and again it wouldn't start after turning it off. I had to have it towed to the dealer again. They confirmed today it was the fuel pump that had gone out. I know I had about a half tank of gas this time. | Crash: No Fire: No | Unknown |
| Apr 2025 | FUEL/PROPULSION SYSTEM | FUEL PUMP. I was driving at highway speeds of about 70mph when I suddenly lost propulsion but the truck was still running. I had cars behind me and coming from the front. I shifted to neutral and back to drive to see if that would fix it and nothing changed. I pulled over onto the shoulder and put it in park. I went back to drive and nothing again. I turned it off hoping for a reset and it wouldn't start after that. The starter was turning over but would not fire up the engine. Had to have it towed to the dealer and they say its the Fuel Pump. No lights or warnings ever came on the dash. The Truck is at the Toyota Dealer being fixed right now. | Crash: No Fire: No | Unknown |
| Jan 2025 | FUEL/PROPULSION SYSTEM | My truck continues to start extremely rough and it staled out on me the other day driving down the road. The problem has persisted for several months now and I have been told that it is a problem with the fuel pump. I know that Toyota had a massive recall on fuel pumps but my truck was not under that recall and believe that it should have been. | Crash: No Fire: No | Unknown |

| Jan 2025 | TIRES | 3 of 4 tires LT285/75/R20 have consistant cracks around the sidewall of the tires rubber showing small shining metal strips | Crash: No Fire: No | Unknown |
| Dec 2024 | ENGINE | This is the second occurrence of "rodent" damage eating engine wires. The first incident cost me $2,000. This has now occurred again. There is something "maybe soy based" or environmentally friendly materials that are attracting rats, and mice to cause engine damage by eating essential wiring and sensors, causing a fire risk, and highway safety risk. | Crash: No Fire: No | Unknown |
| Oct 2024 | ELECTRICAL SYSTEM,SERVICE BRAKES | This case results from the malfunctioning trailer brake ECU on 2018-2019 Tundras. There is a Toyota service bulletin T-SB-0036-19, which specifies an updated controller to replace the defective model. Part # : Original 89547-0C020 Update/replacement 89547-0C060 Toyota will not replace this defective part outside of the original warranty period despite the issuance of an updated replacement part. The service bulletin wasn’t even issued until 4/19 possibly giving no recourse to owners whose warranty had tolled. The newer part number, suggests this was a dangerous defect that was upgraded. A review of this matter online details this problem has frequently occurred. The reason it’s not more commonly reported is that a minority of Tundra owners tow trailers, and even fewer tow with electric brakes. Regardless, this is a significant safety issue where the Tundra owners are forced pay about $1,100 to repair this defective part. This matter should be elevated to a recall since losing the functionality of one’s trailer brakes is a very dangerous situation. | Crash: No Fire: No | Unknown |
| Jun 2024 | POWER TRAIN | I was inspecting the vehicle for an extended warranty company the issue was the transmission. I was in the process of inspecting the vehicle when I was installing the Blue Diver to retrieve the stored codes in the system when I leaned in to turned the accessory key the vehicle started in gear and drove froward. Causing the left front door to close on me from the lift. | Crash: Yes Fire: No Injuries: 1 Medical attention | Unknown |
| Apr 2024 | FUEL/PROPULSION SYSTEM | The vehicle has had no other fuel issues and has always been kept up on maintenance at the Toyota dealership. Recently we had issues after getting gas and it stalling. Today after closer inspection the dealership called to say it was the fuel pump. The fuel pump has melted to the gas tank. This is obviously a huge fire and safety risk. There are no after market parts that would cause this. | Crash: No Fire: No | Unknown |
| Jan 2024 | SERVICE BRAKES | I am having problems with the integrated brake controller constantly disconnecting when pulling any type of trailer. When ever I pull a trailer I never know when the controller will disconnect and I'll lose brakes on my trailer. This happens at any speed while towing. This seems to be a thing for 2018 tundras, as I've read about many other complants. | Crash: No Fire: No | Unknown |
| Nov 2023 | FORWARD COLLISION AVOIDANCE | The pre collision system malfunction - visit dealer warning light came on 11/15/23 Diagnosed by dealer on 11/23/23 as "pre collision radar sensor is not good" Cost paid to diagnose the problem $412.53 Estimated cost to replace the sensor and recalibrate the system $1,112.40 Total cost $1,524.93 This part should be recalled as it has negatively effected the safety of over 500,000 vehicles. It should be fixed FREE OF CHARGE as stated by the manufacturer in its letter sent out to dealers under the Special Service Campaign KOB (Remedy Notice) | Crash: No Fire: No | Unknown |
| Nov 2023 | AIR BAGS | Was rear ended while at a stop in traffic. Was pushed into another truck in the front and ricochet back and was hit again by the car that hit me. After everyone came to a stop my dashboard information center stated the SRS Airbag System Malfunction Visit Your Dealer. My truck was totaled. | Crash: No Fire: No Injuries: 2 | Unknown |
| Oct 2023 | ELECTRICAL SYSTEM | While descending a steep grade towing an 8,000lb travel trailer using appropriate hill descent braking techniques, an error message came on the dash indicating a trailer wiring, type, or connection fault. From this point forward, I had no trailer brakes and was left with truck brakes only. I got the truck/trailer combination to the bottom of the grade safely, however this could have been catastrophic for an inexperienced driver or in a different situation. Upon further investigation, this is a common problem with Toyota Tundra’s, and acknowledged by Toyota in TSB # T-SB-0036-19 issued on April 1, 2019. The dealer and Toyota Customer Service will not acknowledge this, and states it is something only covered under the 3 year warranty. My question for you, the NHTSA, is how would this not be considered a safety issue, when the issue comes on unexpectedly under less than ideal circumstances, especially when Toyota has acknowledged that there is a problem with their brake controller. This is a safety issue, not a warranty issue. Toyota will be held accountable for any injury or death caused by my vehicle in this situation. | Crash: No Fire: No | Unknown |
| Jul 2023 | ENGINE | Cam tower is leaking oil. I was told by the dealership that the oil is dripping onto the exhaust and could cause a fire! The truck is five years old with only 35000 miles on it! Apparently the sealant that is supposed to hold the cam tower together can start leaking oil! But I didn't expect it to leak with this new of a truck and this low of miles! I got on line and apparently this is happening quite a bite on tundras! | Crash: No Fire: No | Unknown |
