2024 TOYOTA SEQUOIA

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING

On three separate occasions we have lost braking power preventing instantaneous stopping, and control of the vehicle. They partially work when your foot is pushing on the pedal all the way to the floor. This occurs autonomously without warning and the following occur: Lose breaking power, inability to brake and stop at safe distances instantaneously and momentarily, Brake ABS alarm, Parking Support Brake Malfunction ("Visit Your Dealer"), Check Engine, Collision Assistance fails, and Traction Control fails. The first occurrence my spouse was driving the vehicle on a 65 MPH three lane highway that at the time was evening rush hour. She had to decrease her speed to 30 MPH in a 65 MPH speed zone in order to slow the vehicle enough at a safe distance from the vehicle in front of her, then continue at a safe distance as traffic ahead of her excelled. Had this happened traveling the speed limit, and had to stop abruptly, this could have either caused severe bodily injury and/or death to her and the vehicle behind and in front of her, and other adjacent lanes. The second occurrence after the dealer looked at it (as covered under warranty), we received the vehicle back. The next day the brakes went out and alarms appeared once again as she pulled out of the driveway. I pulled the vehicle in the driveway for her and couldn't stop and almost drove through my garage at only idling speed. The third occurrence was most recently after an oil change. I drove the vehicle around the block and again, the brakes went out and alarms appeared once again. We have owned this vehicle since May 10th and it has been at dealerships for repair for at least 35 days minimum. On the first occurence they had a regional tech/engineer inspect the vehicle. Nothing was found as problematic and a factory reset was performed - nothing replaced. The second occasion - same outcome... nothing fixed or replaced. The vehicle is in the shop again for the same problem.

I am submitting this complaint to raise serious safety concerns regarding the towing capabilities of the 2024 Toyota Sequoia. Despite its advertised towing capacity of up to 9,000 pounds, this vehicle is dangerously unstable when towing even modest travel trailers—particularly single axle models weighing around 4,500 pounds. During a recent vacation, I towed a properly loaded single axle travel trailer using my 2024 Sequoia. The trailer was equipped with: A weight distribution hitch Anti-sway bars Balanced tongue weight and cargo distribution Despite these precautions, the Sequoia was thrown around on the highway, requiring constant correction and resulting in a white-knuckle driving experience. My vacation was ruined, and my safety was put at risk. The trailer now sits unused in my driveway because I cannot safely tow it with this vehicle. The instability appears to stem from the Sequoia’s: Short wheelbase, which reduces towing control Soft suspension, tuned for comfort rather than trailer handling Hybrid drivetrain weight distribution, which may compromise rear-end stability These design choices make the Sequoia unsuitable for towing travel trailers, even well below its rated capacity. RV dealerships, including Camping World, routinely sell trailers to Sequoia owners based solely on the published tow rating. There is no warning or advisory provided about the vehicle’s real-world towing limitations. This practice is misleading and dangerous. I urge Toyota and the NHTSA to take the following steps: Issue a Technical Service Bulletin (TSB) or formal advisory warning owners about towing instability with the Sequoia. Educate RV dealerships about the limitations of SUV towing dynamics, especially with single axle travel trailers. Investigate owner complaints and consider a broader safety review of the Sequoia’s towing performance. There are multiple online reports and forums where Sequoia owners share similar experiences. This is not an isolated incident—it is a sys

FUEL/PROPULSION SYSTEM

Toyota advertises the vehicle MPG is between 19-22. I am only getting 12 mpg. My low gas fuel light comes on at 10 miles to empty. Engine makes a horrible noise after the vehicle has been driven for 10 to 20 minutes. It sounds like a rattling/old clunker vehicle sound. It sounds like the transmission or engine is going to blow up. Vehicle wobbles when driven over 75 miles per hour. It feels like it is swaying in the rear. I have reported these issues to Toyota on 5 occasions. The first 2 attempts, Toyota told me, could not duplicate/no recommendations at this time. A TSB was issued to fix the rattling sound, took the vehicle in a 3rd time and was told it fixed the rattling. It did not, took the vehicle in a fourth time and was told no recommendations at this time. Took it to another Toyota dealership, and they told me no recommendations at this time. I have had 3 certified mechanics not from Toyota listen to the sound and they have advised me that it is not normal. The mechanics said in order to pinpoint where the sound is coming from, the engine needs to be removed and inspected. But they believe it is an issue with the engine/transmission.

POWER TRAIN

I have a warning lamp turned on notification randomly every week. I took the vehicle to the dealership for inspection and at this point nobody could find the problem.

SEAT BELTS

After exiting the vehicle on 3/7/2025, I opened the rear passenger door (driver’s side) to get my son out of his carseat. I noticed the seatbelt was not attached at the base. In other words, the seatbelt mechanism was not attached to the vehicle. See photos. The black cover which conceals the bolt that holds the seatbelt to the vehicle was also detatched. On 3/10/25 we brought the vehicle to Mechanicsville Toyota and they have requested to keep it overnight. There were no warning lamps or other signs of failure. The seatbelt bolt was not torqued properly at the factory.

UNKNOWN OR OTHER

The rear hitch cover has been on recall for several months now. Toyota does not seem to have a remedy in place for it. And there has been no further communication regarding when a dealer can replace the component. The cover came off and was crushed while driving.

ELECTRICAL SYSTEM

Trailer brake controller failure but i dont tow, 360 cameras stopped functioning and cameras all distorted. Lost the grid lines. Everything is grayed out. They calibrated in 10,26,2024 but same errors. Took it to toyota dealer they cannot fix. They will contact Toyota support.

FUEL/PROPULSION SYSTEM

The fuel door does not stay open. It flaps around. This issue becomes problematic while attempting to refuel and insert the fuel nozzle while fighting with the fuel door. On numerous occasions, I was the wind forcing the fuel door closed while trying to insert the fuel nozzle and I depressed the trigger on accident, resulting in fuel spillage.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING

It has happened 3 times, every time I have been driving and an alert with flash on the dash that there is an object in the road and it will brake check me, but there isn't anything infront of the vehicle. One time it happened getting off the highway and 2 other times it has happened when I was in a residential area. 2 out of 3 times, a vehicle behind me had to swerve to the shoulder of the road, so they didn't rear end me. Second issue, the hybrid system is not working. The vehicle was parked and when I went to put it in drive, the alert popped up and I had to turn the car off and restart. Third issue, the lane assistance. While driving in the middle lane and going around a 20 or 30 degree right turn, the vehicle pulled me into the left lane, almost side swiping the vehicle next to me.
