Owners have filed 357 complaints
about the 2018 Toyota Highlander with NHTSA between 2018 and 2026.
The largest single group is the transmission & drivetrain.
Across this model's run it ranks 4 of 25 worst.
The letter says how bad. This says what kind — whether this year drew
an unusual number of complaints, unusually dangerous
ones, or failures that arrived unusually early.
The dashed ring is 50 — the national norm. Further out is worse.
Complaint volume — 62
Against the median year of the Toyota Highlander. 50 means typical for this
model; 100 means roughly double.
Severity — 98
19% of these complaints
involved a crash, fire, injury or death, against a national rate of
9.7%.
Early failure — 100
71% of failures with a mileage on record happened under
36,000 miles, against a national rate of
29%.
How 2018 compares with every other Toyota Highlander
NHTSA files every complaint against a named sub-assembly, not just a
system. This is the difference between knowing it was "the engine" and
knowing which part of it — the list to hand a mechanic.

Recalls on the 2018 Toyota Highlander
A complaint is one owner's allegation. A recall is the point at which
the manufacturer or a regulator agreed the defect is real and dangerous
enough to fix for free — however old the car is.
Risk: If the fuel pump fails, the engine can stall while driving, increasing the risk of a crash.

Recall 202172355,683 units in Canada
Electrical
Issue: This recall is for certain block heater kits installed on certain vehicles or sold as accessories at Toyota or Lexus dealerships. On certain vehicles, the engine block heater cable may not have enough heat protection and could be damaged by high temperatures. If this happens, the cable could short circuit while plugged in, and cause the wiring to overheat or melt. Note: This recall only affects the following block heater/cord part numbers: C014003034 PK5A408J09 PU14000904 C014003151 PK5A408J13 PU14000905 C014000885 PK5A489J11 PU14000907 C014000888 PK5A489J22 PU14000909 C014000907 PK5A410H00 PU14000911 C014100904 PU14000900 PU14000913 C014100907 PU14000901 PU14003571 C014100911 PU14000902 PK5A489J14 PK5A408J05 PU14000903 Safety Risk: Engine block heater wiring that overheats or melts could create the risk of a fire. Corrective Actions: Toyota recommends that you should stop using the engine block heater immediately. Toyota will notify owners by mail and instruct you to take your vehicle to a dealer to disable the engine block heater. For some vehicles, the corrective actions for this recall are under development. For others, a new engine block heater cannot be installed, and the owner will receive a refund of the purchase price of the engine block heater.
Recall 2020514126,597 units in Canada
Fuel System
Issue: On certain vehicles, the low-pressure fuel pump could fail. If this happens, then engine may run rough or may not start and the check engine light may turn on. This could also result in a sudden loss of engine power while driving. Note: This recall is an expansion of recalls SRC R95/SRC R96 and SRC RA2/SRC RA3 (Transport Canada Recall Numbers 2020-005 and 2020-088). Safety Risk: A sudden loss of engine power could increase the risk of a crash. Corrective Actions: The company will notify owners by mail and instruct you to take your vehicle to a dealer to replace the fuel pump.
Recall 2020088111,835 units in Canada

Recall 2019428327,373 units in Canada
Accessories
Issue: On certain vehicles, the hook and loop material used to attach the carpet to its underpadding may not be flame resistant. As a result, when it is tested alone, the loop fasteners do not meet the requirements of Canadian regulations. Safety Risk: As the carpet is always assembled, and the loop fasteners are very small, this problem does not create a safety risk. Corrective Action: This is not a recall. The company has made production changes to ensure that all new vehicles meet the requirements of Canadian regulations.
Recall 2018155220 units in Canada
Brakes
On certain vehicles, an oil passage in the rotor of the vacuum pump may not have been machined properly and could result in oil not being distributed throughout the pump. This could lead to the illumination of a warning light and message, an audible tone, and a sudden loss of braking assist, which could increase stopping distances and increase the risk of a crash causing injury and/or damage to property. Correction: Dealers will replace the vacuum pump with a new one.
The Pre-Collision System (PCS) failed to engage the automatic emergency braking during a stop-and-go traffic, thereby, resulting in rear-ending the vehicle ahead of our 2018 Highlander Limited vehicle. Our Highlander was at a complete stop, then when the traffic moved slowly forward, we too started moving forward but didn't realize the vehicle ahead of us had suddenly stopped again. Our Highlander alerted us with high-pitched beep-beep-beep sound, but it didn't stop before colliding with the rear of the vehicle ahead of us. The speed couldn't have been more than 10 MPH since it started out from a complete stop and the distance traveled before the collision was about 40 feet. There were no warning lamps, messages or other symptoms of the problem prior to the collision. It always beeped, like it should, when there were nearby obstacles, pedestrians, and when we got closer to the end of our garage parking space, etc. PCS sensitivity was set at the highest level (3 bars).

I was parking my car and was almost to the gray slab to stop when the car suddenly surged forward! It felt like an airplane taking off. I hit a brick building. Somehow my nose was broken, and I was bleeding profusely. If someone had been walking on the sidewalk in front of me, they would have been crushed against the brick wall. Others have had this problem; in fact, one lady said she almost hit a brick wall! Ironic! There was no warning of any kind. However, the day before, while driving on the highway, the car did the same thing: it surged forward, but fortunately I was able to control it, and there had been no one in front of me. If I had been driving locally, I surely would have hit someone, and who knows what the consequence would have been. The Insurance Company towed the car and totaled it.

This vehicle has a UA80 8-speed transmission that has prematurely failed. This is a KNOWN issue to Toyota and they have refused to provide a fix. It is a safety hazard when all acceleration stops when attempting to merge into heavy traffic (as had happened to me last week) or on a highway traveling at top speed. I have only 27,000 miles on this automobile and it failed with NO WARNING! Within a very short time frame the following occurred: the check AWD system, TRAC off, check engine and the transmission fluid at a high temperature lights appeared on the dashboard. Shortly thereafter I experienced a burning smell, suddenly no acceleration with a high TAC response and vehicle jerking. My transmission is toast. This would have ended very badly for me as it failed on a highway at speed with heavy traffic. Toyota needs to address this and recall and replace. Shame on you Toyota!

While driving my 2018 Toyota Highlander Limited, the check engine light began flashing off and on. I was near an exit and drove off the freeway. I could feel the car (near the gas pedal) start shaking, then the power went down quickly... as I was trying to find a safe place to go. The farther I drove, there was less power until the car was going about 2 miles an hour. The check light continued flashing as I pulled into a parking lot. This was very scary as I'm sure the car would have just stopped on the freeway if I had not been near an exit as it just simply had no power left. (The check engine light has been on over a year and I took it to three different mechanics. Not one could fix it. This car wiped out my savings and now sits at a Toyota dealership)!

Transmission failed at 65,000 miles right after the warranty expired. Cost to fix is $8,000. This is an epidemic issue with Toyota Highlanders built from 2017 to 2023. Tried to get dealer to cover but they said they refuse. They said that Toyota Corporate settled by paying all dealerships for potential repairs due to this issue, however all funds have been depleted. Basically no help at all. Pursued issue with Toyota Corporate for several weeks of escalations and appeals. In the end they completely refused to offer any solution other than for me to pay out of pocket. This issue should have been a nationwide recall due to the systemic failure on thousands of Toyota Highlanders.

My car had around 52,930 miles on it when the transmission suddenly went out and left me stranded in [XXX]. I always took my car to the North Hollywood Toyota dealership regularly, twice a year since I bought the car for regular service maintenance. When I was quoted nearly $7,000 to replace the transmission, I sold the car. Why would a 2018 Japanese car with such low mileage and in great condition suddenly have transmission problems? Something doesn’t add up. I had to get towed home. I’m wondering if other Toyota Highlander owners have experienced unexplained transmission problems as well.

Prior to the check engine light illuminating, I noticed a burning smell coming from the vehicle. Subsequently, the following fault codes were retrieved: •P0741 – Torque Converter Clutch Circuit Performance/Stuck Off •P2714 – Pressure Control Solenoid “D” Performance/Stuck Off •P2757 – Torque Converter Clutch Pressure Control Solenoid Circuit Performance/Stuck Off These symptoms are consistent with the known defect described in Toyota’s Customer Support Program ZJC (POL19-04), which acknowledges a manufacturing defect involving an improperly bent washer tab inside the UA80 transmission. However, my VIN was not included in the covered vehicles under this program, despite experiencing identical symptoms. I am also aware that multiple class action lawsuits were filed in December 2025 against Toyota alleging the company knowingly concealed this defect from consumers for years. I am requesting NHTSA to investigate whether Toyota’s CSP ZJC coverage should be expanded to include additional affected VINs, and to consider issuing a mandatory recall for all vehicles equipped with the defective UA80 transmission.

Transmission failure (whining noise similar to the well-documented issue with UA80F 8-speed transmissions). I reported the noise and requested a specific diagnosis at approximately 95k miles --- no warning lamps/warnings were visible, just noticeable noise while driving without the radio on. On May 22, 2026, Torrington Toyota confirmed that the transmission was failed, but vehicle is drivable. As I purchased a Toyota Extended warranty, Toyota has approved the order of a remanufactured unit, which is on back order, so repair date is TBD/unknown. I lack confidence in the long-term viability of remanufactured unit, as this UA80F transmission continues to have issues, and will cost me $12k+ after the warranty expires, in the likely case that the remanufactured unit fails. There should be a long-term fix to this expensive issue.

The transmission went on my 2018 Toyota Highlander. The other day as I was driving on highway, lost power as I was driving in neutral. I went from 70mph to 10 or less mph, would not accelerate. All of a sudden all warning lights. Check AWD, check engine light came on, many messages at once. There were no warning lights displayed prior to this. I was able to get off an exit. Could not move the car anymore was not in a safe area, called police for assistance. The car was towed to an independent service center who confirmed it was a transmission issue.

STEERING
First symptom I noticed was the car smell while it was running. I used a device to see what codes of any would pop up on a scan. It came up with codes tying into the fuel system. I then went to go fill up on gas couple days later and when going to start it back up it wouldn’t start. When it did start it would say engine losing power or steering losing power and then just shut off. I then looked up what that usually means and it made me look towards the alternator. I was told by a mechanic an easy way to see if your alternator was good was to start car and while running disconnect the negative on battery and if it stays running the alternator was still good. So I did that and it stayed running. I then looked up recalls for my vehicle and seen everything it was describing for the fuel system seemed to be happening. I am now filling this form out to get my vehicle looked at and fixed. I have a wife and 2 young daughters that we drive to school. It is not safe to be driving and hoping that us and others on the road will get to there destination safely.
