2023 Toyota Tundra Cruise Control Problems

Your truck hesitates and suddenly loses power when pulling out into traffic, particularly at stop lights. This has happened multiple times and feels like a throttle problem — on one occasion, the power loss caused another vehicle to hit you. The dealer couldn't reproduce the issue during testing. Fixing this will likely involve diagnosing the throttle control system and possibly replacing sensors or fuel system components.

Your truck hesitates for several seconds when you press the gas pedal from a complete stop, creating a dangerous delay when crossing traffic or merging onto busy roads. The dashboard shows no warning lights and the truck is in normal mode, but this delay puts you and other drivers at risk. The issue may be related to the vehicle's speed control system and should be diagnosed by a dealer to identify whether it's a transmission, engine, or electronic throttle control problem.

Your vehicle hesitates when accelerating from a stop and doesn't always respond smoothly to your pedal input, which could put you at risk of a side collision. Your lane keep assist system is also problematic—it frequently fights your steering input and pulls your vehicle off the road or over lane lines, making it difficult to maintain control.

The issue is with the auto-braking or pre collision system. Have had multiple instances where system has engaged at low speed which also engaged the auto engine stop feature when it was not necessary. Have noticed system engages on roads with curves where it thinks the vehicle in the other lane is in front of me when its not.

Your truck experiences a severe delay when accelerating from a stopped position, particularly during left turns across oncoming traffic. When you press the gas pedal, nothing happens for 2-3 seconds before the engine suddenly surges forward, creating dangerous situations. This happens intermittently but almost daily, and no warning lights appear before it occurs. The issue may require diagnostic testing and engine control module reprogramming or replacement to restore normal throttle response.

Your truck occasionally stalls and loses power when you're merging onto the highway from an on-ramp. When this happens, you lose acceleration and the truck coasts without responding to throttle input. The dealer has been unable to reproduce the issue despite multiple visits over the past year.

Your truck experiences dangerous delays when you press the gas pedal—sometimes taking several seconds before the engine responds. This lag is particularly risky when you're trying to accelerate into traffic or make quick turns, as your truck may just coast while you wait for power to kick in. The issue has happened multiple times since you bought the vehicle. This will likely require a diagnostic scan of your engine's throttle control system and possibly a software update or replacement of throttle components.

When you stop your truck and then try to accelerate again, you might experience a delay before the engine responds. You press the gas pedal but nothing happens at first, then the truck suddenly accelerates abruptly. This throttle hesitation and delayed response happens during the initial acceleration after coming to a stop.

When you press the gas pedal from a complete stop or while merging onto the expressway, your truck hesitates and doesn't respond immediately. This happens frequently and creates a safety concern, especially when you need quick acceleration to merge into traffic. The issue appears to be related to how the transmission responds to throttle input, and a transmission inspection or reprogramming may be needed to restore normal acceleration response.

Your truck sometimes delays 2-3 seconds when you press the gas pedal from a complete stop, then suddenly surges forward with power. This happens most often right after starting the vehicle and has occurred about 4-5 times since 10,000 miles. This delay could create a safety risk when entering traffic. The issue may involve checking the throttle response system, fuel delivery, or transmission programming.

Your truck hesitates or lags when you accelerate, especially after turning a corner. This delay has created unsafe situations where other vehicles almost hit you from behind. The issue appears to be related to how the engine responds to throttle input in these driving conditions.

Your truck hesitates for 2-3 seconds when you try to accelerate after slowing down but before coming to a complete stop, creating a dangerous delay when pulling into traffic. This hesitation has nearly caused accidents because the truck doesn't respond immediately when you press the gas pedal. The issue likely involves the transmission, fuel system, or engine control computer needing diagnosis and repair to restore normal acceleration response.

Your truck sometimes hesitates when you try to accelerate from a complete stop — you press the gas pedal but the engine responds slowly, causing you to pull out more slowly than expected. On one occasion, you lost throttle power entirely while in traffic. Your dealer flashed the engine computer (ECU), but the problem persists. Fixing this may require further ECU reprogramming, throttle body cleaning, or replacement of engine control components.

Your truck has a delay when you press the accelerator—it takes a few seconds to respond instead of accelerating immediately. This lag has caused dangerous situations, such as nearly being hit while turning at an intersection because the truck wouldn't speed up when needed. The issue happens repeatedly and is inconsistent with how other vehicles respond to throttle input. A mechanic will need to diagnose the fuel delivery, throttle sensor, or engine control system to find what's causing the delayed response.

When you slow down to very low speeds and then try to accelerate again, there can be a noticeable delay (up to 1 second or more) before the engine responds to pressing the gas pedal. Your truck's computer acknowledges the accelerator input but doesn't immediately increase power, which can make the vehicle behave unpredictably and create safety concerns. The issue appears to happen when the transmission shifts down to first gear. A dealer has verified the problem and opened a case with Toyota for investigation.

Your truck's accelerator pedal sometimes doesn't respond when you press it lightly—you have to push it all the way to the floor before the engine accelerates. No warning lights appear on the dashboard. Two Toyota dealers test drove the vehicle but couldn't reproduce the problem, so they didn't diagnose or repair anything. The issue started around 21,000 miles. Fixing this may involve inspecting the throttle cable, electronic throttle control sensor, or fuel injector components.

Your truck occasionally hesitates when you press the gas pedal from a stop or while rolling. Instead of responding immediately, there's a brief delay (usually less than a second) before the engine catches up and the truck suddenly jerks forward. This happens randomly almost every time you drive, though most of the time the throttle works normally. The issue likely involves checking the fuel injection system, throttle body, or engine control software.

When attempting to accelerate, the vehicle idles down and fails to accelerate for a period of 2-3 seconds. To initiate normal acceleration, fully depressing the accelerator pedal is required vs. a gradual depression of the pedal.
