Transmission/differential - Took my car in around 80k miles for a routine transmission service. I got my car back and it started making a whining noise when you accelerate. Never did I get a code, check engine light nothing. Took it back to get looked it since the sound never went away. I am being told it needs a new transmission. I was told my car transmission was too hot for them to even look at after sitting for 24hr parked! I have read and done a lot of research that this is a common issue and never has been recalled. Even a shortage now on transmissions with so many needing them now! My car is only 3 years old and won’t be covered.. this should have been recalled and or known to buyers before purchasing if it was known to have issues early 2021…

The vehicle is a hybrid. While traveling downhill at a speed around 35 mph with light brake pressure, the vehicle feels like it lurches forward a second or so before returning to braking. It has occurred since we purchased the vehicle new in 2021. It has happened multiple times in a variety of scenarios but it occurs most consistently in the downhill scenario described above.

Transaxle Repair/Replacement: recommend transmission replacement due to whining noise coming from transmission due to internal failure. The transaxle is the transmission for front wheel drive vehicles. The transaxle transfers power from the engine to the wheels. Unsafe driving conditions issue is stemming from faulty transmission, not only on this particular vehicle but many 2021 Toyota Highlander vehicles for the same transaxle repair/replacement issue. I have gone to Toyota multiple times before and even with a Technical Service Bulletin in place for this transmission issue, they did not correct the problem, nor fix it while it was under warranty. Toyota has been aware of this Technical Service Bulletin since Feb 9 2021. T-SB-0008-21 [XXX] Owners of the 2021 Toyota Highlander have reported various transmission problems, including: Whine or Grind Noise: Some vehicles exhibit a whine or grind noise from the transmission, which may be caused by an issue with the front carrier assembly pinion shafts1. Jerky Gear Shifts: Drivers have experienced jerky gear shifts, especially when accelerating from a stop or slowing down to very low speeds2. Delayed Shifts and Hard Shifts: There have been complaints about delayed shifts, hard shifts, and lurching when shifting gears3. Transmission Slipping: Instances of the transmission slipping between gears and jerking when accelerating have also been reported4. Safety Concerns These transmission issues pose several safety risks: Loss of Control: Jerky and delayed gear shifts can lead to a loss of control, especially in situations requiring quick acceleration or deceleration. Increased Accident Risk: Transmission slipping and hard shifts can cause unexpected vehicle behavior, increasing the risk of accidents. Driver Distraction: The noise and irregular shifting can distract drivers, reducing their focus on the road. Mechanical Failure: Persistent transmission issues, or stalling.

Our Highlander has a recall for the clips on the front bumper. A few weeks ago, my wife was driving behind a truck pulling a trailer. My wife that it was a set of caster wheels that flew out from the trailer and made contact with her front bumper. Upon inspection the impact from that debris put a crack in the upper front bumper. No other visible damage was present. Later that day while my wife was driving 75 on the interstate, the defective clips from the recall gave way and the lower front bumper gave way and started to drag on the ground. Luckily it stayed in tack enough that the vehicle did not run it over causing my wife to wreck or even worse having other vehicles needing to avoid it on the interstate. We paid for a tow truck to safely take it off the interstate so we could tie wrap the lower bumper up and take it to the dealer. Toyota recall does warn that light impact to the bumper could result in the bumper falling. It also goes on to say that if the clips cannot be changed out, they will replace both the lower and upper bumpers. I took the car to the local dealer, and they confirmed that the clips could not be replaced due to the damage that had been done. I showed the dealer the recall notification on the internet, and they stated they could not do anything as they were not a body shop. So, I opened a complaint with Toyota Customer Care [XXX] ) and stated my case. They in turn notified a local dealer to address the issue. I have called customer care twice not without the dealer even trying to contact me. Due to there faulty part, my wife could have been in a much more serious accident. I would like your assistance in have Toyota make good on their commitment to replace both the lower and upper bumper as a result of the light contact that created this situation.

The sunroof exploded in 75 degree weather. My safety was put at risk by the sunroof exploding and others were put at risk that were following on highway from flying glass. The problem was confirmed by safelite. Toyota refuses to take any responsibility. The sunroof was inspected and repaired by safelite. There was no warning that the sunroof was going to explode. The vehicle maintenance is at the highest level.

Excessive whining noise, shift flare. The vehicle is only a couple of years old. I was told by the dealer that the transmission will likely need to be replaced. There are numerous complaints within the Toyota Nation forums. It was recommended that we report the incidents here, as having a large number of cars on the road with failing transmissions can certainly be considered a road hazard/safety issue.

The start/stop operating system failed. When the engine cut off while waiting for train to pass, the engine went to turn over and completely stopped the vehile. Although the car would not start, I was unable to cut the car off completely. It would say ignition on. The lights in vehicle were on. Running the ac caused the car to say high power consumption but there was no way to cut vehicle off without removing the battery to reset the vehicle. Caused the car to malfunction while sitting at a complete stop. Also cause the parking break to engage and I was unable to disengage parking break. A message came across saying parking break unavailable. My safety and others were put at risk because had it happened at any other time a crash would have been caused. It caused a roadway to be blocked off which caused confusion and near accidents.

I noticed in March of 2024 that the lower part of my bumper was starting to detach. So I brought my car in to get inspected while I was getting my car serviced. Their was a recall issues in 2023. When the dealership looked at my car they said their was no remedy for the recall that I would have to wait until their is one. They said they can not fix the car even though the lower bumper was already starting to detached. Now July 27, 2024. While driving the bumper fully detached and now I’m dragging the bumper underneath my car. Had to take it to a mechanic to get it removed and then saw my dealership to get it fixed because of the recall. Now My bumper got fully detached and I suffered because of this Recall problem. Dealership said they can’t fix the problem that it was because of a collision that happened from a previous owner of the car that got into a collision in 2021. Where I bought the car in 2023 where the bumper was not detached and now I’m suffering because the dealership said Toyota corporate won’t fix the car under the recall. Now I’m stuck with fixing a bumper where I never got into an accident and could of been injured because of this bumper falling while drive and I have to pay out of pocket to fix it.

The electric park brake makes a loud screaming sound during engaging cycle as I put the gear in park. The sound gets worse during warmer weather. I visited the dealer twice for the same problem and reported it to Toyota. During my visit another highlander came into dealership. It made the same sound when the driver placed it in Park. According to the dealer, this sound is normal. I say it’s not. I have way cheaper cars with Electric park and they don’t make this sound. If the park brake unit fails it’s going to be real costly to repair and may fail while driving and gets engaged.

THE ENGINE COVER ASSEMBLY DETACHED FROM THE BOTTOM OF MY CAR WHILE DRIVING. SIMILAR TO THE EXISTING RECALL FOR THE FRONT LOWER BUMPER COVER ASSEMBLY. While pulling out of a parking lot, I noticed that there was a scraping noise under my car. Prior to parking at Jones Beach State Park, I was traveling on Ocean Parkway at a high rate of speed (50-60MPH) and it was a very windy day. I did not hit any obstructions or scrape the bottom of my car on anything. There was nowhere for me to pull over and as I sped up, the noise went away. When I got off the highway, the noise returned. When I got home, I looked under my car and there was a plastic piece dragging just in front of my front tires. I remembered I had received a notice about a Toyota recall related to the lower front bumper cover assembly and looked that up - it felt very similar to what I had experienced. When I got to the dealer, they told me it was not subject to the recall and the repairs on this would be $200 diagnostic plus $529.88 parts and labor. I was told I must have hit something to make it detach. I did not hit or scrape anything. My car has pretty good clearance, it would have had to be HUGE for me to hit or scrape it. I would have known.

I am VERY concerned that Toyota hasn’t taken this more seriously. I notice in the NTSB website it has injuries and fatalities listed to the left of the complains. Does someone have to be injured or killed before Toyota gets their act together??? Thinking we may need to trade this for another SAFER, RELIABLE vehicle. I have also had many people flash me due to the headlights being too high and in their face-another SAFETY concern.

When braking, there is a momentary period where it feels like the brakes fail, then function again. When approaching stopped traffic, this could put those vehicle occupants, and our vehicle occupants at risk of an accident. Toyota maintains this is normal for a hybrid, however our 2013 Camry Hybrid has no such momentary brake failure. Our independent repair shop has been unable to replicate this condition , but they have found no obvious problems with the braking system - they believe it is something computer caused, likely when the hybrid generation brake switches to the hydraulic brake. There are no warning lights displayed. This has been a long standing issue.

When decelerating from a speed of approximately 25 mph on a downward slope of about 5 degrees, and applying the brakes, a number of things occur: 1) There is a 1-2 second delay in the braking action. 2) When applied the braking action is less than expected for certain brake pedal pressure, which causes the driver to increase the brake pedal pressure 3) When the brake pedal is initially depressed, the speed of the vehicle experiences a slight upward speed bump before the braking action is applied, which is 'light' as described in 2). This behavior is transient. Most of the time, it does not happen. It happens often enough to be of concern.
