2026 Toyota Tundra Engine Problems

“I was attempting to enter traffic from a steep driveway. I removed from foot from the brake and pressed on the accelerator, there was no power and the vehicle would not increase speed. This lasted about 2 seconds. It was a 50 mph roadway and the approaching vehicles had to slow quickly to avoid a collision”

“My 2026 Toyota Tundra TRD Pro developed a sudden, loud knocking noise from the engine at approximately 15,000 miles while I was driving. The engine began running very rough, the vehicle started shaking, and the engine was losing power as I pulled over. The knocking was most noticeable at low RPM and followed engine RPM. There were no warning lights or warning messages before the problem occurred. I was able to safely pull the vehicle off the road, but the sudden loss of engine power and severe shaking created a safety concern. …”

“I was turning left from a stop sign on to a busy road. Immediately after beginning to pull out, the engine stalled and left the truck powerless in the middle of the intersection. I almost got t boned from vehicles traveling both directions. The truck eventually regained power a few seconds after the stall.

Searching online, many owners have had this happen and Toyota refuses to do anything meaningful. …”

“The engine in my 2026 Toyota Tundra has significant throttle delay/lag when its cold - even if I let it warm up - it still has significant delay in throttle response - the truck has poor light throttle response and then lurches (even with the most minute progressive throttle input). This almost caused an accident where I nearly got T-boned because the vehicle crept a bit and then suddenly lurched quickly. The vehicle was also hesitant to reach 60mph (even though it was warmed up) after about 10 minutes of driving the vehicle started operating normally. …”

“I bought the vehicle new in November 2025. 2026 Toyota Tubdra TRD SR5. In the first week I noticed a lot of jerking and shaking. I brought it to the dealer and was told it was a break in period and it should go away. I’ve had the truck in the shop 5-6 times since and the jerking and shaking hasn’t gone away. I’m at 6300 miles now. The dealer won’t even respond to me anymore. The only way to make the jerking go away is to step on the gas pedal harder but this has become extremely dangerous because it’s forcing me to go faster than I would like, especially in school zones. …”
