2025 Toyota Grand Highlander

I continuously have issues accelerating from stop in my max hybrid. the issue is particularly worse when it is warm out. I press the gas and the RPMs drop really low and I barely move through the intersection for a few seconds. Once it finally registers after a number of seconds, the RPMs rev up over 4000. It is very dangerous trying to proceed through an intersection and the car basically stalls when I press the gas. It especially concerns me that I have my child in the car with me and I worry when it is going to act up. I know others have experienced this issue and there was a TSB for 2024 models that had this issue. I have a 2025 and experience this issue. I have had toyota look at it and they said they cant do the TSB since it's bot for my VIN. A solution needs to be found for the the safety of myself and others.

After a complete stop at a stop sign there is hesitation/stalling when trying to accelerate. Sometimes the hesitation is several seconds and then the engine kicks in and lurches forward. Couple times this has been a safety issue as it happens when I’m trying to pull out on a busy road. The delay/hesitation has caused me to almost get hit a few times. There are no lights or warning messages when this happens. It happens a multiple times a week especially during hot weather when AC is on full (LO temp setting and maximum fan) and is usually during the first few minutes of operation usually at the same stop signs on my route to pickup my kids after the car has been sitting unused overnight. I also notice that the hybrid battery indicator is usually always at 3 bars. Dealership hasn’t been able to reproduce as it's a very specific scenario (not driving/in garage overnight and short drive). Instead they went and applied T-SB-0040-25 but this hesitation is still happening after the software update. This needs to be handled like a safety issue/recall worthy with a complete fix! Not just some drivability issue that only gets applied if we ask about specific T-SBs.

On occasion the car will not accelerate from a dead stop like it should. I think it’s turbo lag. There have been a few times I thought I was going be broadsided pulling out into traffic when normal acceleration would have been safe but with a dead pedal for a few seconds it was terrifying. I’ve brought this up to two different dealers and they say without being able to experience it there’s nothing they can do. Someone going to die because of this.

After coming to a complete stop at a stop sign or stop light, then trying to go, the vehicle will stall. It will not go when given gas. The first time it happened, I was at a busy intersection with oncoming traffic coming towards me with the pedal to the floor, nothing would happen for 5-10 seconds. It was terrifying. Thank god the car coming towards us went around in time. It then happened again in my neighborhood a week later. Thankfully that time I wasn’t in traffic. I have noted that it seems to happen when very hot outside (Florida July summer) and air is on full blast. Also seems to be happening only during the first trip of the day, within the first 5-10 minutes of said trip. The dealership has not been able to recreate this to see for themselves. I think it would have to be with them overnight and they start it/drive it for the first time that day. It has now happened a total of 3 times since I’ve been driving it (2.5 months). I have 3 children and very worried I will get t-boned one day when it stalls next. I love my car so much so it’s heartbreaking that I have to drive it in fear. No lights/warnings/messages when this happens.

The electronic parking brake on my 2025 Toyota Grand Highlander intermittently fails to auto-release when shifting from Park to Reverse or Drive. Curiously, the system does respond to the gear shifter when returning to Park, as the brake will then engage or release as expected once cycled. This indicates a failure specifically in the transition out of the Park position. This intermittent delay or refusal to release prevents the vehicle from moving when expected, creating a potential safety hazard in traffic or during time-sensitive maneuvers. No dashboard warnings are present, and the issue occurs even when the driver's seat belt is buckled and the foot brake is fully depressed.

Dear National Highway Traffic Safety Administration, I am submitting this complaint to formally report a serious safety issue involving the left front axle of my Toyota Grand Highlander Hybrid XLE. The vehicle was first diagnosed by my local Toyota dealer on January 14, 2026, at which time the left front axle issue was identified. I contacted **Toyota Motor Corporation**, and I was initially informed that the required replacement part would arrive on February 6, 2026. After that date passed, I was told the part would arrive in early March. I have now been told it will not arrive until late March. Based on these repeated delays, I am concerned that “late March” could easily become late April or even later, with no firm commitment or guaranteed repair date. I have contacted Toyota dealership multiple times and made several phone calls seeking assistance, updates, or a definitive timeline. Unfortunately, no one has been able to provide a clear solution, firm delivery date, or alternative support while the part remains on back order. Due to the axle issue, I do not feel safe operating the vehicle, as I believe it presents a significant safety risk. This vehicle is essential for my work and daily financial responsibilities. Because I do not feel it is safe to drive, I am unable to use the car to earn my day-to-day income and meet my financial obligations. As a result, I am currently losing wages, and the prolonged delay is causing financial hardship and significant inconvenience. Given the safety implications and the ongoing lack of resolution, I respectfully request that the National Highway Traffic Safety Administration review this matter. I would appreciate guidance on the appropriate next steps, including whether this issue warrants further investigation, inspection, or potential recall action. I also seek clarification regarding what protections or remedies may be available to consumers when critical safety components are unavailable for extended periods.

At a complete stop my car started shaking violently back and forth. It felt like we were in an earthquake. It has happened before but not as violently and not as long. No warning lights or anything. It has had problems with lurching and stuttering since we bought it. The dealership said they fixed it once (the stuttering) but it’s still happening. They cannot duplicate it and it’s not throwing any codes.

While accelerating from low speeds and turning, the car exhibits a rotational clicking noise from one or both front drive shaft assemblies. Seems to be the identical issue noted in the 2024 Grand Highlander that was presumably fixed during later production lots (T-SB-0082-24). That issue was seemingly solved with driveshaft replacement. The dealer said they “could not duplicate” the issue; however, it happens often while I am driving the vehicle and others have reported it to the same dealer as well. It seems to be an existing related safety issue that the dealer, and potentially the manufacturer, are ignoring until we get past the warranty.
