Electrical system
26 reports1 crash2 fires1 related recall
“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.”
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.”
Fuel/propulsion system
16 reports
“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.”
Vehicle speed control
14 reports
“All of a sudden the pre-collision system malfunctions and stops working and the lights go on in the dashboard and then causes the cruse control to stop working as well. I took it to Toyota and they stated they did not know what the cause of it would be.”

13 reports1 crash1 related recall
“THE BLUETOOTH SIGNAL (PHONE CALLING) KEEP DISCONNECTING. THE DEALER, TOYOTA OF SEATTLE TRIED TO FIX 4 TIMES AND THEY REPLACED THE UNIT LAST TIME BUT I STILL HAVE THE SAME PROBLEM. THEY KEEP BLAMING ON APPLE IPHONE.”
Engine
12 reports
“The vehicle is a 2018 Toyota Tundra and failed state inspection at an authorized dealership due to the power steering rack and pinion assemble leaking at both ends. This is the same failure described in Toyota recall 21V920000, but Toyota claims my VIN is not covered. This is a severe safety issue occuring preamturley at 54,000 miiles.”
