2017 Toyota Highlander complaints

After getting gas, the vehicle will not start. It will crank and crank but not turn over, like it is starving for gas. Then after 10-15 minutes it will start barely and to keep it running I have to floor the accelerator. Any other time it starts just fine. There are also no codes causing a check engine light.

I have had this car seat for 1 year and 10 months and I just found out that the headrest foam piece is split in half (06/26/2025). It has been handled with extreme care and I got it in September of 2023. It has stayed in my specific car and the only reason I found the problem was because I was cleaning them off. It is the third Chicco car seat to have found the foam headrest either broken in half or completely separate from the plastic base in 2 months (2023 & 2024 manufacture dates). There is something wrong with this and I really hope an investigation starts so that others can avoid these issues and potential repercussions from said flaw.

I have had this car seat for 1 year and 3 days and I just found out that the headrest foam piece came off the plastic base frame(06/26/2025). It has been handled with extreme care and I got it in June 2024. It has stayed in my car and the only reason I found the problem was because I was cleaning them off. It is the third Chicco car seat to have found the foam headrest either broken in half or completely separate from the plastic base in 2 months (2023 & 2024 manufacture dates). There is something wrong with this and I really hope an investigation starts so that others can avoid these issues and potential repercussions from this flaw.

Car suddenly began to slip out of gear and have difficulty shifting smoothly. After having car examined by 2 repair shops it was determined the UA80 Transmission needed replaced. Repair shop advised car was not safe to drive with this condition. Warning lights for Check Engine and Check AWD system and traction control came on at the same time as the slipping and rough shifting.

Car is shaking heavily when stopped. Several misfires while engaging the brakes. Mechanic is telling me that he has seen many vehicles of this model with faulty purge valves.

The transmission on my Highlander is making a whining noise. I took it to Blackstone Toyota Service for inspection, in Fresno, CA, after my own mechanic inspected it and told me that it was a transmission problem. Toyota told me that the transmission is going out and the car can quit on me at any time and is no longer safe to drive. But since it is out of warranty now they will not do anything to help me with this problem. There has been no warning lamp, message or other symptoms yet. After my service in Nov. 2023 i noticed a slight whine when i accelerated. I had a friend mechanic look at it and he said it could be just because the tires had been rotated. A couple of months ago the whine started on deceleration. I took it to Johnson Auto in Clovis, CA and they were the first ones to tell me it was in fact a transmission problem. I then called Toyota call center and was told that the vehicle needed to be inspected by one of their dealers, and then they could help me. I explained that I didn’t want to go spend more money on the inspection if Toyota would not do anything to help me, I already knew it had transmission problems. I took it to Blackstone Toyota Service Center and they confirmed that the transmission is going out, at only 7800 miles. I called the Toyota call center and was told that since it is out of warranty they will do nothing to help me with this problem. I told them the prior agent I had spoken to said that Toyota would help me. I was told they will do nothing

Driver side interior visor has failed and does not secure in place causing obstruction of view while driving.

My 2017 Highlander XLE AWD had complete transmission failure at 106,000 miles. Toyota has an extended coverage warranty for this but according to them my VIN number was not included even though it failed for the same reason as the recalled transmissions. Loud whining started around 100,000 miles on acceleration around 30mph and continued to get louder. From a dead stop it is very slow to accelerate and misses 3rd gear and jerks. There is a TSB out on this and the extended customer satisfaction extended warranty ZJC but they refuse to cover. I was also told by Toyota corporate that even if my VIN was affected they would not cover due to all maintenance not being done at a toyota dealership. I am the 4th owner and should not be penalized for this. My case number with Toyota is Toyota Brand Engagement Center Case 250416002071

Known issue with the transmission assembly that results in a whining noise and eventually hard shifting and transmission failure. Known issue acknowledged by Toyota across this model and date, but they seemingly are only addressing some vehicles - and not others - with said known issue.

Transmission failure requiring replacement. Known pattern failure from Toyota. Customer support program from Toyota does not cover all affected vehicles.

With 22k miles on vehicle, car won’t start due to Brake power low fault. Battery was replaced in attempt to rectify problem with no success, vehicle will need to be towed in for repair.

Toyota manufacturing issue-fuel line is manufactured incorrectly-had gas seeping into cab of vehicle and tailpipe. Severe safety issue Steering wheel/column sticks and almost lose control when driving due to a worn out coupler-poor design and manufacturing.

Transmission intermittently allows the RPMs to double from 2,000 to 4,000 RPMs. It occasionally displays trouble codes, and exhibits a grinding, whirring noise. An Independent transmission shop confirms that it needs to be replaced. Toyota has issued a recall referred to as Customer Support Program ZJC, but their representatives claim that our vehicle does not qualify, even though the date and model of the transmission clearly Falla under their parameters.

Side mirror (glass) shakes/rattles at speeds over 45mph. This affects the visibility of things in the mirror as well as becomes distracting to the driver. When on the interstate with smooth pavement it's impossible to ignore... It's just more noticeable then. Tried moving the mirror to verify and yes, it's loose. Just reporting it now that I became aware of this website but car has had this issue for at least 2 years.

The contact owns a 2017 Toyota Highlander. The contact stated that while his wife was driving approximately 35 MPH, the vehicle lost motive power with several warning lights illuminated. The contact stated that an image with the brake pedal depressed was displayed. The contact was informed by his wife that the vehicle then stalled. The driver was unable to restart the vehicle and assistance was provided to push the vehicle to the side of the roadway. The driver was able to restart the vehicle after several attempts.

As the electronic back hitch was closing, I pressed the Start Engine button and the vehicle dashboard lit up but would not start. Then I pressed the button again and it said the Ignition is On. Pressed again to shut off. Vehicle made a bunch of clicking noises but would not start. Disconnected battery to “re boot” electrical system… but a charger on battery and then the vehicle started. BUT the ! And Check Engine light was now on… saying take to your dealer… Check AWD. Drove vehicle at lunch time… and warning light and check engine light just went off! So weird!

Several weeks ago my wife noticed that the vehicle skids when accelerating and she told me about the situation. I hardly drive the vehicle because I was not aware of the situation, but today I drove it and realized what is happening. I am not a mechanic to give a diagnosis of the situation. For me it could be the transmission and it only has 85K. I'm going to do the next oil change at the dealer. Right now I do them at Firestone, it's close to my house and for me it's more convenient.

The contact owns a 2017 Toyota Highlander. The contact stated that the vehicle was parked but still running in a driveway on an incline. After exiting the vehicle, there were abnormal beeping and ticking noises detected, and the vehicle began to roll down the street. The contact and daughter were pinned between the door and the vehicle. The contact's daughter sustained injuries to her chin and teeth. The driver has lumps and bruises on her leg and back pain, but medical attention was not provided. The rear wheels were on the curb and hit a trash can, and the vehicle stopped rolling. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 70,000.

During the Multi Point Inspection, technician inspected the vehicle. He checked the engine, transmission, and cooling system, topping off all fluids. However, the engine was failing inspection as there was oil underneath the vehicle, which was also seen around the engine, due to an oil leak.

2017 Highlander with the Auto Start/Stop. It will sometimes go completely dead when idling, like at a stop light. Completely dead meaning zero electricity - no lights. This will last a couple of seconds. But one day, the car died at a stop light right. No power. Completely dead. Couldn’t turn on my hazard lights Gears were stuck. Couldn’t shift gears.

My car has 18600.0 miles on it the problem is i started getting a " brakes under powered find a safe place to park" after doing some research, i have been advised to replace the vacuum pump and power booster at cost of aprox. 4 thousand dollars the car is not safe to drive i am disabled so this creates a hard ship for me. this is a major brake component why does it need to be replaced with only 18600.0 miles on it this is my only from of transportation and yes the mileage is correct

While accelerating onto highways, my Toyota Highlander suddenly misfires, causing rough engine and a natural response to decelerate instead of continuing to accelerate. The ignition coil was blamed, I replace and then a week later it happens again while trying to accelerate on the highway. Another replacement and then it happens again a third time. There was a known issue under Toyota’s TSB 0148-19, where engine computers were reprogrammed and all coils replaced. My vehicle model year and engine model but doesn’t show this TSB. I am aware TSBs are not recalls, but the sudden repeat engine misfires, all in a year, while accelerating to highway speeds, is a concern.

In city driving, vehicle began exhibiting slightly delayed shifting from 1-2 and 2-3. Downshifts from 3-2 seemed slightly rough. Approximately 5 minutes later when accelerating from a stop on an uphill grade, the shift from 2-3 was delayed (2nd gear disengaged, engine speed increase ~1000RPM, then shifted to 3 abruptly). At next stop, lower gears where not available. Vehicle seemed be in 4th(?) gear when accelerating from a stop. Very little power available. Had to engage hazard flashers and other vehicles navigated around our vehicle. Managed to limp car ~ 1 mile to home. Approaching driveway, Master Warning Light, Check Engine Light and 4WD Warnign light all illuminated. This issue created a loss of power that impaired the drivers ability to maintain a safe speed relevative to traffic. Had this issue occurred during high-speed operation, the vehicle may have been disabled in a high-risk area. Transmission appears to be unreliable.

Bought it used from Lexus Fremont with 46, 600 miles on March 2024 but after driving it for just a little bit over 200 miles, there is a leak underneath the engine and when I had it checked here in Salinas Toyota they found out that the leak is coming from the TIMING CHAIN COVER of which is a big job and I heard a lot from the owners of this Toyotas with the 2GR V6 Engine has this leaking problem.

Water pump has failed at approx 80,000 miles.

The contact owns a 2017 Toyota Highlander. The contact stated that while driving 50 MPH, the vehicle started jerking, the RPM decreased, and the vehicle started losing motive power. The message "Reduced Engine Power" was displayed. The contact stated that she came to a complete stop at a traffic light. The contact stated that while attempting to drive from a complete top, the vehicle stalled. The contact was able to restart the vehicle; however, the vehicle jerked increasingly while driving. The contact veered to the side of the road, where she remained. The contact stated that the failure had been occurring for months. The vehicle was previously taken to the dealer, where it was diagnosed and determined that the low-pressure fuel pump had failed. The vehicle was not repaired. The contact related the failure to NHTSA Campaign Number: 20V682000 (Fuel System, Gasoline) however, the VIN was not included. The manufacturer was notified of the failure and informed the contact that they could not assist because the VIN was not included in the recall. The failure mileage was approximately 125,000.

Hi- i have always upkeep the maintenance on my vehicle and take pride taking care of it . But now out of nowhere my vehicle throttle was loose the mechanics can’t explain why and now the transmission is not working i have explained to them them driving the car does seem to stop them feels like it wasn’t to accelerate while driving. I don’t know if anyone else have reported this issue but it doesn’t make sense that for a vehicle le that’s been greatly taken care of the transmission is went out .

I just bought this car and I noticed when the car is sitting and idling it has a strong smell of raw gas in the passenger compartment. I took it to the fire department and they smelled it as soon as they opened the door. They also said this is not safe and I shouldn't be smelling a strong odor of gas in the passenger compartment.

2017 Toyota Highlander experienced delayed and rough shifting in 3rd gear. Safety of acceleration is affected, especially merging onto highways. Diagnosed with bad transmission on 12/26/2023 by Toyota service. There was no warning lamps or messages prior to failure. Unknown cause, car is regularly serviced per manufacturer recommendations by Toyota. Part on backorder for approximately 3 months.

I HAVE AN ISSUE WHEN MY AIRBAG LIGHT KEEP ON GOING IN AND OUT. I DID GET A LETTER FROM TOYOTA THAT SOME AIRBAGS IS RECALLED BUT WHEN I TOOK MY CAR TO THE DEALERSHIP THEY SAID THAT MY CAR IS NOT INCLUDED ON THE RECALL AND THEY WONT TROUBLESHOOT IT WITHOUT HAVING TO PAY. NEED THIS LOOK AT THAT CAN CAUSE FATAL TO THERE CUSTOMERS.

While braked at a red light, my vehicle completely turned off. The engine would not restart, and all electrical panel light indicators did not come back on. I could not even turn on my hazards. The whole car was dead. After about a minute, I was able to restart the vehicle, but it took 5 attempts. I changed my battery two months ago, and just had my car checked by a mechanic and nothing was found to be the problem. No warning lamps or other messages were displayed. About 6 months ago, my car did something similar to this and stalled on the freeway in bumper to bumper traffic. However, this time the electrical panel light indicators came back on. No warning messages displayed. The car restarted after only one try. This is really dangerous to have a vehicle loose all power and completely die out!

I had an accident on 1/14/24 and the airbags did not deploy. When we bought the vehicle from I-5 Toyota it had been in a previous accident and was repaired. I have a picture from the dash stating “ SRS air bag system malfunction” on the day of incident. The vehicle is being picked up by insurance 1/18/24 to be inspected. There were no warnings prior to the accident.

The contact owns a 2017 Toyota Highlander. The contact stated that upon entering the vehicle and attempting to buckle the seat belt, the contact became aware that the seat belt was no longer attached. No warning lights were illuminated. The vehicle was taken to the dealer, who determined that the anchor point bolts were severely corroded. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 75,000.

There is a toyota service bulletin for known transmission issues with this vehicle. I had noticed that my gears weren't shifting properly. The dealer checked vehicle and said transmission was bad, and that toyota would replace it, for free. However, the part would take one month to arrive. This all occurred on 1/9/2024. I was told by the dealer that Toyota would not cover a rental car while the part was on order, but only for the repair itself. The dealer told me the Toyota recommendation was to not drive the vehicle -- but other customers had done so until they received their parts for repair. I picked up my vehicle after work at approximately 7:15pm. While driving, the vehicle completely shutdown on me in a major highway miles from downtown Philadelphia, in a flooding rainstorm that produced nearly 4 inches of rain. If Toyota knows there is a problem with this vehicle and its transmission, then why is there no recall? And if I'm being told the I should not drive the vehicle, then why isn't it mandated or required for them to provide me a rental - especially since this is the fault of Toyota?

I had my battery replaced about 3 days ago at the Toyota dealership . Yesterday, I was stopped at a red light and when I attempted to drive, the vehicle stalled. “Braking power low” message on the dashboard and the car would not restart. I was able to jump start it after about 30 minutes. I got towed to a local repair shop who could not identify or duplicate the issue. I had no warning indicators other than failing to start the morning of getting the battery replaced 3 days ago.

This 2017 Highlander Blizzard Pearl White paint is defective on the drivers side door. Paint started to bubble in 2021 then peeled off with rust stains underneath due to water damage. It appears that there is no sealant on the door for the paint to adhere so it continues to peel and rust. A defective paint job on this vehicle when manufactured. Please have Toyota take responsibility for their irresponsible paint job on this door. The vehicle has never been in an accident or hit with anything on the drivers side of the door. They need to correct their incomplete and incompetent painting. There seems to be no sealant underneath for the paint to adhere to. Please address this error.

The contact owns a 2017 Toyota Highlander. The contact stated that while driving at an undisclosed speed, the vehicle inadvertently lost motive power. As a result of the failure, the contact was unable to maneuver or control the vehicle before coming to a complete stop in the middle of the roadway. The vehicle returned to normal functionality, but the failure became a regular occurrence. The check engine warning light was illuminated. The vehicle was taken to an independent mechanic, who was unable to determine the cause of the failure and advised the contact that a Toyota technician needed to diagnose the vehicle. The vehicle was not repaired. The manufacturer was notified of the failure but did not assist. The failure mileage was 66,000.

Highlander shift issue 11/14/2023 On 11/14/2023, our 2017 Toyota Highlander, vin# [XXX] , upon driving the transmission decided on its own to disengage. Our Highlander stopped propelling itself in either direction. We had to manually push our vehicle into a parking spot and await the tow truck. Our Highlander is in mint condition with 71,400 miles on it. This was scary because the vehicle would shift on the shifter, but for some reason the transmission would not engage. The engine worked perfectly fine. We had the Highlander towed to the nearest Toyota dealer who pushed the vehicle into their garage and placed on a lift. The Highlander had no idiot lights on, no cable issues, fluid was fine per the Toyota Technician. The Toyota Tech placed the vehicle on their main computer and there were no error codes. The Tech reset the computer on the vehicle with a Toyota Master computer, and the vehicle started to work as normal. I consider this a huge issue and I thank God that my wife was not on the interstate highway when this happened. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

This is the SECOND incident with this vehicle in the past 4 months. When going to start my vehicle, it would not start. It gave me this error message: Braking power low, Stop in a Safe Place, See owners manual. There is NOTHING about this in the owners manual. The first time I thought it was battery related and after 3 different chargers on my vehicle, it finally started. Tonight I proceeded to push the button without the foot pedal and the radio came on, so it is definitely not the battery. I've tried several times to start and to no avail. Problem has not been reproduced as i cannot drive my vehicle at this time. No inspection as of yet. No warnings or symptoms prior to failure. Research shows it may have to do with a fuel pump pressure issue. I have paperwork on this issue under a customer support program 23TE01. Hoping this can become a recall and i can get this fixed .

About two weeks prior to the transmission failing, I started hearing a high-pitched whining coming from the transmission, difficulty shifting, and lurching forward when engaging the gear. On the evening of October 4th, my wife was driving at 65 mph on a busy freeway in Atlanta when the vehicle lost acceleration. She was nearly hit while stopped on the freeway. Fortunately, kind motorists got out of their cars and pushed her to the side of the road. The car was towed to a Toyota service shop, and we were advised they could not do the repairs. The mechanic stated it was a known internal Toyota issue. I did some research online and found hundreds of posts from Highlander owners of 2017-18 vehicles complaining about issues with the transmission failing. I found Toyota Customer Support Bulletin POL [XXX] dated 4/18/2019, REPAIR COVERAGE FOR UA80 TRANSMISSION ON CERTAIN 2017-2018 MY SIENNA AND CERTAIN 2017-2018 MY HIGHLANDER VEHICLES. The mechanic said the failure code with a failed transaxle and all the symptoms my vehicle experienced were consistent with the bulletin. My time period for the bulletin was for cars produced from November 2016 to December 2017. My vehicle’s manufacturing date was 12/8/2016. Toyota claims my vehicle although produced during this time was not impacted. It is my belief that Toyota was aware of multiple failures on UA80 transmissions on vehicles produced from 2016 to 2020 and deliberately identified a smaller number to avoid a recall. INFORMATION REDACTE

Toyota issued a Customer Support Bulletin #POL 19-04 on 4/18/19 for vehicle transmission failure on the 2017 and 2018 Highlander and Sienna cars due to faulty assembly. Dealerships were issued the bulletin 5 years ago but customers were never alerted. Toyota has refused to honor the repairs claiming my VIN did not come up for affected car even though bulletin list the model that includes my car. The bulletin further states that after 60k miles the coverage continues for up to 10 years from date of purchase. Toyota knows there is an issue but they failed to alert customers despite sending the bulletin to dealers. Dealerships never alerted customers who brought in their cars for routine service. Thousands of customers are reporting failed transmissions. Toyota is not able or willing to provide information on how they identified which VINs were impacted. The mechanic pulled a code which is exactly what is being seen on the failed transmissions in the same vehicles and cannot understand why Toyota will not cover the cost of the repair for a known defective product. The replacement cost quoted by Toyota is in excess of 11k. The car failed on a busy freeway in Atlanta while traveling at high speed. Motorists exited their cars and pushed the vehicle to the side of the road. My spouse could have been harmed or worse killed.

Driving on the highway vehicle suddenly drop speed. I was able to exit but not proceed forward once exiting. The vehicle was towed and diagnosed with need for new transmission. There was a customer support program bulletin POL 19-04 noting similar problems. However, Toyota is stating this 2017 is not associated with the program. The whine noise and reduced power are all listed with this program. The vehicle sudden reduce power may have resulted in a major accident on busy Atlanta highways. A known transmission issue that Toyota is not willing to support customer in resolving is unbelievable. I was basically told because the vehicle was not serviced at a Toyota dealership regularly, they cannot support.

I am writing in reference to a new Toyota Highlander that I purchased in December of 2016. The reason I chose Toyota over a Ford or GM SUV was Toyota’s long history of producing reliable vehicles. I researched and relied on Consumer Reports which gave the Highlander and Honda Pilot the highest rating for customer satisfaction and reliability. About two weeks ago I started hearing a high-pitched whining coming from the transmission, difficulty shifting, and lurching forward when engaging the gear. Last Wednesday my wife was driving on a busy freeway in Atlanta when the vehicle lost acceleration. She was nearly hit while stopped on the freeway. Fortunately, kind motorists got out of their cars and pushed her to the side of the road. The car was towed to a Toyota service shop, and we were advised they could not do the repairs. It was a known internal Toyota issue. I did some research online and found hundreds of posts from Highlander owners of 2017-18 vehicles complaining about issues with the transmission failing. I found Toyota Customer Support Bulletin ,[XXXXXXXX] REPAIR COVERAGE FOR UA80 TRANSMISSION ON CERTAIN 2017-2018 MY SIENNA AND CERTAIN 2017-2018 MY HIGHLANDER VEHICLES. We called Toyota support on 10/9/23 and spoke with a customer service representative named Amber who then transferred us to Vena. They advised based on the VIN number our vehicle was not covered. Vena advised that since all our service was not at a Toyota dealership, they could not honor the repairs. Th

Brake system malfunctioned and failed. Our safety was put at risk with no braking ability. The car was inspected and serviced by Toyota. One light showed braking power low on one occasion While driving car listed above, on five different occasions the brake pedal went to the floor with out stopping the vehicle. Our safety was put at risk on each occasion.

While driving all of these lights started to flash.

I’m not sure why this recall does not show up for my car & we’ve never been notified by Toyota. I have a video of the noise my makes when it’s off on the driveway…I can provide an alternate way as your online system does not allow video. Thank you.

On Aug 28 2023 I drove my car to Cumberland’s for a coffee (.9miles/3m away) on my way back at a stop sign, before turning left onto 129, my car shut off. I pushed the engine button, it restarted & I made it back to my house. Since owning this car this same situation has happened randomly several times, brought it to the dealers attention, not happening at the time, cannot be replicated, nothing was done. I remember being on a hill on 129 at a red light & the car shutting off loading control thinking I was going to roll into the car behind me I pulled the e rake since this was a repeated issue, the car started when I pushed the ignition, another time this happened at a red light not on a hill as well as the highway off ramp in stopped traffic. We eventually replaced the battery clearly that’s not the issue since it has continued to happen. Sometimes my radio will randomly shut off, sometimes it reboots & i get nervous & prepared for my car to stall or shut off which creates a distraction driving. I may have a video of one of these times that I took to show my husband. I do have a video of the radio shutting off that I can provide an alternate way as your system does not except video files.

My car would randomly shut off at red lights, one time I was on a hill & thought I was going to roll back into the car in front of me. After restarting it would turn on. The radio would randomly shut off. We eventually replaced the battery. On a Fri.(Dec 17th) my car would not start, so my Husband drove the kids & I to school, upon my return the car started. He told me the wheel locks & I need to move it. Then on Mon. (Dec 20th) driving my daughter to preschool school…I have video from home camera showing your system will not let me attach a video) …my car stalling as I reversed out of the driveway. I loose all control, then you hear that I pulled the emergency break & stop just before two cars pass by. I then restart the car, it goes, I drive 3 houses down I pressed the break to make a left turn onto a side street, my car accelerated & smashed into a telephone pole on the drivers side. You can hear the crash on my home camera. The impact was so hard, it bent my a frame, my airbags did not deploy, my drivers side door would not open. I shifted the pole & cracked the frozen dirt ground around it as seen in the pics. I can provide a copy of the body work repairs. We paid our $1k deductible. The car jpeg image icon does is not show like the other pics attached, so I attached a screen shot as well. We have other pictures & video’s of damage to provide upon request

The contact owns a 2017 Toyota Highlander. The contact stated while his wife was driving inside the parking lot of a gas station, the steering wheel seized and then the vehicle stalled. The contact stated no warning light was illuminated. The vehicle was not drivable. The contact stated that a bystander assisted with jumpstarting the vehicle. The contact drove the vehicle to a nearby Walmart and was informed that the battery needed to be replaced. The contact purchased and replaced the battery. The contact called and made the local dealer aware of the failure. The vehicle was not diagnosed. The manufacturer had not been informed of the failure. The failure mileage was approximately 106,000.

Car started to not start after getting fuel. Come to find out the purge valve was remaining stuck open. Dealer told me that this was concerning as it was allowing vapor to gather in my engine. Vehicle was confirmed by two different Toyota dealerships to have faulty purge valve. The purge valve would cause all the warning lights to come on in the Highlander, telling you your AWD system was bad to other warning lights. In doing research this seems to be a problem in various years of Toyota Highlanders. Concerning that something related to controlling fuel vapor could be this common and leading to a build up that could cause something more serious to happen.
