36 Electrical System problem

Failure Date: 05/09/2022

On occasion I have been walking around this car while its just parked in my garage and I hear a a humming sound like a electric gas pump. This is 4 hours after it was used last. It is a faint sound coming from the the rear seating area. Just before I started to write this I went out to check it again and its not doing it. This is not a one time event and its concerning since I believe its electric and may be involved with gas in a parked garage. The vehicle is in like new condition and had one minor cosmetic type accident while in its first year of use. Scratches to driver side panels and front bumper. I will call the dealer tomorrow to see what they have to say. Thanks in advance for any info you can share on this issue, a fire in my garage would bad.

37 Electrical System problem

Failure Date: 11/30/2021

I was driving and stopped at a red light on 4 lane intersection (very busy). I went to press on the gas and my car would not move. I put it in park and and then back in drive. It still did not move. It "died". I looked at the dash and it said "electrical system - move over to a safe place". My car would not start - I could not move it. I was stuck in the middle of the street -scared out of my mind. I had to call 911 and they told me someone already called for me and the police were on their way. When the police came he told me to stay in my car and he would stay behind me. There were no warning lights or anything to let me know that this was going to happen. If there was, I would not be in the middle of a 4 lane road. Toyota states it is the start-stop battery system. This is completely unsafe.

38 Electrical System problem

Failure Date: 10/01/2021

Since having recall work done my vehicles computer system has not been functioning the same. My vehicle has been stalling out and saying braking power low,stop in a safe place, charging system malfunction. I’ve reached out to haley Toyota 8301 midlothian turnpike, richmond, va 23235 where the diagnostic was done and let them know of the error code I was given ( p0335) crankshaft position sensor “a” circuit. I took it in for diagnostic there and they told me they couldn’t find any issues with my vehicle , ( picked up oct. 3, 2021). It’s oct. 4 , 2021 and here I am at sams club trying to leave but my vehicle will not start. I contacted Toyota again and let them know of the same issue and they said to once again bring it in for diagnosing. I asked the gentleman on the phone if they had previously had it for a week and didn’t seem to find any issues with it after doing diagnostic then what were they planning on doing differently. My vehicle is under warranty and I’m trying to figure out who and where I can take it to to get some answers.

39 Electrical System problem

Failure Date: 09/18/2021

I was involved in an accident that I believe was caused by sudden unintended acceleration (sua). In a very busy commercial parking lot, I was pulling into a parking space proceeding at a very slow speed, when there was a sudden surge in acceleration accompanied by a grinding/acceleration sound. I hit the brake to no effect, and the vehicle jumped the curb and hit a building shop and entered the shop. The air bags did not deploy, and I was shaken up but not injured. Thankfully, there was no one at the front desk area of the business. The car was not drivable and was towed to a body shop.

41 Electrical System problem

Failure Date: 07/10/2021

Sporadically, when starting up the vehicle, from the overhead console, it emanate a loud, ear piercing sound that is painful to one's ears. Apparently, this is a known issue with 2019 Toyota Highlanders in the limited platinum trim level. This issue has been presented to the dealership numerous times (darcars Toyota frederick) with their claim they could not recreate the issue. I have provided video evidence but still no action was taken. Now out of warranty, it occurs more frequently now with this piercing noise.

2019 Toyota Highlander hybrid. Today exactly one year from purchase it stalled on a busy public roadway for the 4th time. With the 4 incidents in June, July, & sept 2020, the car, without warning 1. "powered down" almost immediately to a dangerous slow point with no acceleration in response to pressing gas pedal in the following locations: a high traffic major urban bridge(40mph); interstate highway(75mph); coming into busy city intersection(5 -10mph); country highway (45mph) 2. Power steering was slow and difficult. 3. Master warning light activated. Audible tone/constant beeping activated. "hybrid system malfunction. , pull over to safety, call dealer, check engine, pcs" , and multiple other warnings. 4. Within moments the car completely died (before I could seek legal and/or safe parking. ) safe parking required multiple attempts. In July (illinois) the car required towing off very busy interstate highway. Assessed as "no issues". Within one hour a Mini-series of sputtering, choking, stallings in city intersection, dealership then kept our vehicle overnight. More lengthy diagnostics "threw" fuel codes. Bad gasoline? today car should have been towed but Toyota roadside assistance denied my VIN & phone# existed in their database. Home dealership confirms I am, without doubt, in database. During hour+wait for assistance, dash cleared of all warnings w/ ignition. Home dealership advised driving to closest dealership. 5 miles. My car currently sits in a missouri toy. Dealership w/ fuel pump suspect. I was told repairs could take up to a week. 97 fuel pumps currently back ordered in parts system. 20,500 miles/all service plan requirements met promptly. I have all inspection forms/service receipts. No ability to upload documents now but would like to be contacted by NHTSA for more information and to share service documents.

After 3wks I found out that I have to push the start button 2x with the engine off to get it to work. Toyota has know about this for 2 years but no one includijng support told me about it! will there be any recalls? it is too late to take it back! I will have to do this each time I use this feature.

While driving in a city warnings on instrument panel came "hybrid system failed", "all wheel drive failed", "take car to the dealer", and the car stopped. Had to have it towed to the dealer. Following day the dealer called me to say that everything in the car checked out ok and they couldn't duplicate the problem, I'm now very weary of taking the car on a trip because I don't know when it may quit again. The car just turned 10k miles.

48 Electrical System problem

Failure Date: 12/24/2019

We started the vehicle that is parked in front of our house at around 8am to get some groceries. The vehicle started and everything seemed normal. Shifted to d and started moving and as I was leaving the spot, I pushed the break to make a left turn and it won't stop. Pushed the break pad several times and the car won't stop. Finally moved the gear to p and it stopped and the engine turned off. I started the engine again and tried to reverse it, it won't reverse and only going forward. I called autonation Toyota of leesburg, they towed the vehicle. The vehicle was purchased on 11/30/19 with only 45 miles in it. It was a frightening because my neighbor was putting something to his car and I was about to run at him.

49 Electrical System problem

Failure Date: 09/01/2019

The computer/radio automatically shuts itself off and then reboots. It has done this too many times to count. It does this randomly and unexpectedly. It becomes dangerous because I live in a state where I am not allowed to hold a phone while driving, so when I don't have wireless phone capability it is very disruptive. It is also dangerous and inconvenient when it happens when I'm using navigation in an unfamiliar place, I am left stranded. There have been times when it continues to reboot continuously during my trip to or from someplace. I have been to the dealership 5 times to have my computer reset/rebooted and the problem still occurs. The second time I took it, the technician left the service ticket open so that each time I took it after that they were putting the "repair" under the same ticket so that it only showed as 1 repair! I now know of at least 5 other people having the exact same problem between Toyota Highlanders and Toyota 4 runners. My vehicle has been both stationary and in motion while the automatic shutoff of the computer system occurred. Of course the dealership always says my computer never shuts off while my vehicle is there, even though it does it when I drive off the lot, so I recorded video of the radio/computer shutting off while I was driving and showed it to them. I would hate for the problem to escalate or become more dangerous.

50 Electrical System problem

Failure Date: 08/01/2019

The entire voice guidance system is inoperative on my one week old 2019 Highlander hybrid platinum. No audible voice or beeps with navigation assist, no phone assist,, no eyes-free assist, no driver announce to rear cabin voice, no entertainment system voice assist. This is a safety hazard eliminating hands free driving, and no navigation guidance. I was on unfamiliar roads in the dark of night, alone, unable to operate necessary equipment which proved to be unreliable. I just learned that this issue has been known to Toyota for several months, yet new vehicles are driven away from dealerships by unsuspecting new owners after paying good money for a defective vehicle. Deceitful, unethical, and unsafe! where is the recall for this issue? why are vehicles not fixed before being sold as new?.

52 Electrical System problem

Failure Date: 02/02/2019

In navigation, it will not give voice directions which is a safety hazard causing you to look at the screen and taking your eyes off the road. I told Toyota about this but no fix. This is dangerous and needs to be fixed immediately. This occurs when stationary or moving. This happens every time you try to use navigation.

53 Electrical System problem

Failure Date: 02/01/2019

The voice commands for the vehicle do not work which requires the driver to look at the navigation screen or scroll through their phone book rather than using the bluetooth features. This is very distracting and illegal in some states which require hands free phone.
