2019 Toyota Highlander complaints

Transmission started making a whining noise. Auto shop confirmed it will need a new transmission.

Whining sound when when pushing the gas to accelerate. When you let go of the gas it stops.

A wine and hard shifting, toyota does not agree. I experience this issue several times a day. Taking it into the dealership again to try to diagnose.

There has been a high incidence of this model of Toyota Highlander having faulty transmissions. My vehicle had 129,000 when the transmission failed. It was metal shavings in the fluid. I’m hoping you will put pressure on Toyota to recall or help replace these transmissions. Thank you.

When I start the Highlander, there is a loud (hurts your ears) feedback noise through the speakers, and the red and green lights near the SOS button flash multiple times. This happens intermittently, and when it doesn't happen the SOS button only flashes red/green once. My wife, the primary driver of the car, has slowly developed tinnitus and this is the only loud, ear piercing, noises she have been exposed to. This noise can also bring on extreme headaches. I can't imagine the damage it could do to a child. We have tried to get this fixed at the mechanic and Toyota says the part is backordered. When we go to Toyota they state they have not heard of the issue. When we search the internet it is easy to find threads of this same issue on the same model, Toyota seems to be hiding this is a known issue.

• Transmission Failure. Inspection is available upon request. • We do not know if we are at risk if the transmission fails while driving. • Certified Toyota Dealership diagnosed and deemed failure – recommends full replacement • Component was inspected by a certified Toyota dealership • No warning lights

Less than 95k miles. Dealer says transmission needs replaced and cooler. Bought new- owned 5 years and 2 months. Many other 2019 highlanders online stating same problem.

Upon acceleration, the engine revved high and a whine sound started once the car (2019 Highlander XLE) approached 25-40 miles per hour. It appears that this is a transmission issue that Toyota was aware about years before selling the 2019 (and later) Highlander and other models (according to consumer complaints online). The car has 92,700 miles on it and is thus out of warranty. It had a recall in 2020 though I do not know exactly what was allegedly fixed. Had Toyota disclosed these serious transmission issues, I would not have purchased the car. My local mechanic has advised that the transmission will need to be replaced at a high cost.

Hello, it seems that my vehicle is having a whirling noise when accelerating at different RPMs. When I researched, it isn’t an isolated incident because many others online are experiencing the same issue with most of them being told that the transmission must be replaced. And further investigation, I found that the issue could be the trans axle assembly component which can cause issues if not replaced.

2019Toyota Highlander = Transmission whine and hard shift at times, Needs replacement transmission at 106,000 mile , no codes stored

When starting the vehicle, and extremely loud feedback noise is emitted from the front right speaker. This happens intermittently. Sometimes it's every 5th time you start it, and sometimes every 29th start. This started happening after the dealer-provided SOS Safety subscription expired. The noise is extremely loud and very disturbing especially for individuals like our daughter who has special needs. I would not be surprised if it is damaging our hearing. It would likely be especially harmful to children! It has been confirmed by the dealer and is currently back at the shop whule they are further investigating the cause.

At approximately 85K miles my 2019 Highlander began to exhibit a high pitched “whirring” sound upon accelerating. The noise stops once you take your foot off the gas. I brought the vehicle to my local Toyota dealership to investigate the noise. They concluded that it is the transmission and I would need to replace the entire transmission. There are no warning lights or other indications aside from the sound. Transmission fluid is clear of any shavings or other indicators of an issue. Toyota service stated they could not tell me if or when the transmission might fail, just that it should be replaced. There are multiple reports of similar occurrences on online Toyota forums. There are also recalls for the exact same sound for the 2018 Highlander. I opened a case with Toyota customer service and was told there was nothing they could do to assist.

Complaint Regarding DCM Module Failure in 2019 Toyota Highlander Platinum Our 2019 Toyota Highlander Platinum is experiencing severe audio system malfunctions, beyond simple Bluetooth and connectivity failures. The vehicle sporadically emits an extremely loud screeching feedback sound upon startup and at unpredictable times while driving. This deafening noise is highly distracting to the driver, posing a significant safety risk. Toyota has been aware of this issue for years and documented it in Technical Service Bulletin T-SB-0112-20, which identifies the faulty vehicle assembly locations. However, despite widespread reports from owners and the high cost of repairs, Toyota has failed to issue a recall. Given the clear safety hazards associated with this defect, I firmly believe Toyota should recall affected Highlanders and provide immediate replacements for the defective DCM module. Owners should not be forced to cover costly repairs for a known issue that compromises driver safety.

A whinning noise can be heard from car while driving. Vehicle has just under 60k miles and dealer is saying the transmission is failing and it would need to be replaced. There was no warning lights or indication on display.

2019 toyota highlander bought 3/15/25 with approximately 82,000 miles. Started making whining noise 4/7/25. On 4/9/25 took vehicle to dealer 4/11/25 notified need new transmission and transaxle seal need on new transmission. 2 weeks later on 4/25/25 picked up vehicle drove home 3 days later noticed gear oil leaking and sprayed all over under chassis. Vehicle brought back to dealer on 4/29/25. On 4/30/25 notified needs new transaxle seal on new transmission. Notified on 5/9/25 new transmission will need to be replaced again. They stated there is gouging/nicks where transaxle and transmission connect. Dealer is saying there is no transmission to put in. Toyota has put a stop to all transmissions. So now I have a vehicle with only 82,000 miles and no way to fix it.

Transmission failed while driving down the highway almost causing an incident. These transmissions are very unsafe and should be recalled. Toyota refuses to take responsibility for this year Highlander although it is the same 80ua transmission that was recalled in the 2017 and 2018. While Toyota has said this problem has been remedied in the later years it is very false. Please do an investigation on this before people get hurt from accidents if they haven’t already.

Transmission makes a whine noise and also experiencing some harsh shifting. Dealership confirmed the whine noise is an indication of transmission failure and they recommend replacing the transmission. Toyota needs to do a recall on this transmission!!

The transmission completely failed. it is at Spitzer Toyota in Monroville. PA

While driving my Hybrid System Malfunction, check AWD, check engine, and Pre-Collision System Malfunction all came on simultaneously, it also said to put in P. It wouldn’t accelerate so I had to have it towed to the dealer since it had only been 3 days since I bought it. It was sent to a Toyota service center where it took 3 weeks for them to diagnose and replace the high pressure fuel pump. I got the vehicle back, it drove fine for a week until the same thing happened again. It stopped accelerating, said to shift into P-only the Hybrid System Malfunction, check engine, and Pre-Collision System Malfunction came up this time. I had it towed back to the Toyota service center since the problem clearly wasn’t solved and am awaiting a new diagnosis.

Transmission failure; See attached Customer Support Program Bulletin No. POL19-04 [XXX] (for 2018 Highlanders). My vehicle is a 2019, same body style, same transmission type, etc. Toyota dealership diagnosed my vehicle today and confirmed that the issue is the same as listed in the bulletin. I filed a case with Toyota (corporate). I have located thousands of other customers online reporting the same issue as described in this bulletin. I'm requesting that Toyota modify the bulletin or create a specific one for 2019. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

We have noticed a whinning noise as we accelerate the vehicle. Doing some investigation online I came across a lot of threads with the same issue. Seems to be the transmission.

My 2019 Toyota Highlander with 56K miles has a whining noise whenever the accelerator is pressed. The noise stops when you release the gas pedal. This was confirmed by my Toyota dealership service department. The transmission does need to be replace. They said this is a common problem with this vehicle and yet there has been no recall. Fortunately my vehicle is still under warranty. I found manner similar complaints about this transmission on the Toyota Highlander Forum. I don't understand why there has not been a recall. Going forward I am also concerned that the replacement transmission could very well have the same problem.

My Highlander transmission has an internal failure. The Toyota dealership declared “transmission has internal failure quote. I am afraid to drive it due to it breaking down on the highway.

Dear Staff, after SEVERAL payments made for DIAGNOSTICS i feel like I should commit suicide maybe because of this TOYOTA I can not afford to pay DIAGNOSTICS every single day to HEAR the SAME STORY over and over I understand there is a ENGINE CHECK LIGHT, I need it repaired PLEASE instead of having to pay DIAGNOSTIC FEES which ADVANCE AUTOPARTS doesnt even charge and TOYOTA takes $172 DIAGNOSTIC FEES when they can not even themselves RULE OUT the PROBLEM in their ENGINEERING or MANUFACTURING PLEASE look out for similar issues, ENGINE problems in 2GR-FKS engines as more people experiencing issues will CONFIRM its TOYOTA's fault They should either shut down their manufacturing in Japan or BRING BACK the STANDARDS of JAPANESE AUTOMOTIVES

2GR engine family in general used in Toyota and Lexus, may have a MANUFACTURING defect as per google about the 2GR-FE engine subtype Yes, the Toyota 2GR-FE engine, a 3.5L V6 found in many Toyota and Lexus models, is known to have a recurring issue with head gasket leaks, particularly where coolant leaks externally from the engine block due to corrosion around the cylinder head where the coolant port is located; this is considered a common problem with this engine type. Key points about the 2GR head gasket issue: Leak location: Coolant typically leaks outside of the engine block, visible as stains on the block surface, rather than internally into the combustion chambers. Cause: Corrosion around the cylinder head near the coolant port, often exacerbated by road salt and old, acidic coolant. Prevention: Regularly changing coolant and occasionally hosing down the engine block, especially if you live in a region with heavy winter road salt. Repair: Replacing the head gasket usually requires removing the engine, making it a major repair job. So TOYOTA should be held liable for REPAIR COSTS and LABOR as well as the PAIN and SUFFERING a consumer has to go through, seeing all the drama of the TOYOTA

While at a stop sign fully stopped the car rolled forward on several occasions. My warranty had just expired a month prior. My car has always been maintained and maintenanced. I was stuck paying a lot of money and no car should be moving when you have your foot on the brake. The dealership said master cylinder/ brake booster went out.their is a recall on the hybrid for the same exact thing but not my car.

A safety alert popped up on my dash regarding an airbag malfunction. This would be similar to other recalled models of my vehicle but for some reason my vin is not on that recall. This is a huge safety concern for me and my family and looking to have our vin added to the recall.

Vehicle has 80k miles. When slowing the vehicle down to 10-20 mph and then trying to accelerate again the transmission bangs/clunks into gear and is delayed to get going causing a safety concern. No warning lights on

Vehicle started making intermittent whining noise around 75,000 miles but Toyota service advisor at the time told me it was normal and since my transmission had been serviced on schedule, it was nothing to worry about. Around 135,000 miles the vehicle sometimes would operate completely normal, and at other times would suddenly seem to struggle to get up to speed especially on the highway somewhere between 20-60 mph. Also sometimes difficult to go at stoplights; but then would resume completely normal operation. The risk to us was we could have easily been hurt in an accident had the vehicle not been able to operate normally at normal speeds, leading to a collision. There were no warnings nor stored codes; the vehicle had received all routine maintenance on schedule including all major maintenance such as transmission services performed by a Toyota dealership. When taken in for this problem, they claimed that they were not able to replicate the jerky/intermittent issues during their test drive, but the whine was indicative of transmission failure and the transmission would need to be replaced. The remanufactured transmissions were on backorder with no ETA, which I was told could be 6-10 months of a wait due to a parts shortage. My service advisor recommended I trade in the vehicle instead because they could not guarantee the vehicle would be safe to drive and I could not continue to drive fearful of a wreck, so we had to do that, and the vehicle was traded in.

AHB, which is part of Toyota's TSS (total safety system) fails intermittently and because the system is run by a sensor, headlight may or may not be illuminated during periods of darkness. Given the intermittent nature of the failure, it seems like there should be something to indicate to the operator that the lights are either on or not on, but the green light indicator goes on and off without any warning, meaning lights are on or off, operator has no way to remedy the issue at highway speed, causing an extremely dangerous situation.

Transmission whine stated on or around 52000 miles. Whine progressively increased in volume over the next 2000 miles. Toyota dealer analyzed the noise and recommended the transmission be replaced. Transmission out of warranty. Independent transmission shop confirmed transmission internal pump was failing and could cause transmission lockup at speed.

Automatic transmission makeing a whinning noise.Many other customers complaining about same problem. Car has 72,000 miles on it which puts it out of 5 year/60,000mile warranty.Customers feel that toyota should cover replacement or repairs cost knowing they have had same problem with 2017/2018 models and have not corrected the problem with the 2019 model.Very unprofessional for such a high quality company.

When I release the gas between 40 to 60 km a whining sound. Dealer says transmission has to be replaced I have 103,000 km.

Within a 3 hour span, car started whining when accelerating and engine would rev and accelerate but wouldnt go. By lunch time the car would accelerate but go nowhere. Transmission failed within a morning.

My car is leaking into my interior. It has come out of the electrical component areas. I worry it has infiltrated airbags & what could happen if they get wet (go off due to damage or not go off when supposed to). Have taken to dealership 3 times with no resolution

When starting the 2019 Highlander, the car would intermittently emit a screeching noise. This noise is startling and can potentially cause a crash if it is emit while driving. This is a known issue since it made to the Toyota Forum: [XXX] However, when I brought the car to the dealership, they’re stating that they don’t know about the issue, and want to charge $300 just to diagnose the problem without guarantee the fix or acknowledge the known issue.

While driving up hill in snowy and icy conditions, my engine RPMs suddenly went up to 4000, then quickly back down. When I tried to continue driving, the car would not switch gears. It was stuck in what I think was 5th gear. I was slugging along at about 5mph. At this point I put the car in park, and waited in confusion for about a minute before putting the car back in gear. There were no warning lights on my car and nothing else to suggest anything was wrong. I tried to move forward up the steep hill, but the car would not go. I put the car in park again and then switched into reverse instead of drive. At this point I had no option but to back down the narrow icy road. I was driving the going to wrong direction backwards, but it was my only option to get me out of the way of others traffic. The conditions made it more dangerous, but this would have been dangerous on any given day. I was able to back down, get my car to flat ground where I parked, shut the car off, waited about 10 mins, and then turned it back on. After turning it back on I was able to drive the car down to the mechanic shop where they told me that my transmission was bad. In hindsight i should have had it towed, but I'm thankful I made it to the shop safely after the transmission warmed up a little. I'm now waiting 3 or 4 weeks to get a transmission directly from toyota (a $5000 part). The repair in total will cost nearly $8000!! This isn't something I can afford to do, especially near the holidays, but I ha
