| Dec 2023 | SERVICE BRAKES | DRIVING DOWN THE STREET WHEN AN ALARM WENT OFF STATING "BRAKING POWER LOW" AND TO "STOP IMMEDIATELY". VEHICLE TO BE TOWED AND TAKEN TO LOCAL CAR DEALERSHIP. OVER THE PHONE, THE DEALERSHIP CLAIMS NO BRAKING ELEMENT HAS BEEN RECALLED FOR MY PARTICULAR VEHICLE, HOWEVER OTHER HIGHLANDERS FROM THE SAME YEAR MODEL WERE RECALLED FOR BRAKING ISSUES (VACUUM PUMP.) HAVE BEEN HAVING ISSUES WITH THE "START/STOP SYSTEM MALFUNCTION" ALARM GOING OFF AS WELL FOR SEVERAL MONTHS, BUT DEALERSHIP STATES IT WILL NOT AFFECT THE DRIVABILITY OF THE VEHICLE. | Crash: No Fire: No | Unknown |
| Dec 2023 | POWER TRAIN | My transmission started making a whine sound upon acceleration, and at times hesitation of acceleration (inconsistent). Toyota Service identified the issue in 2018 as a defective part from manufacturing and related in the repair notice to Toyota Service Bulletin TSB-160-18 which states certain Highlanders (my year and model) have an issue with a defective part in the transaxle/transmission. Toyota issued an extended warranty for the problem in 2020 (unlimited miles for coverage). I was then told that it then DIDN'T apply to my VIN, even tho it was the problem diagnosed by a Toyota service technician associated with the TSB above, so they wouldn't cover thru the extended warranty. Told me that I have to pay for a new transmission over $9,000. My understanding (I cannot verify) that the initial service bulletin was expanded to cover more models in 2021, then removed the extended warranty, and did not issue a recall. Apparently Toyota is aware of a serious transmission problem caused by a defective part, and it is wider issue. This needs to be addressed as it is a significant hazard and danger Toyota is aware of, and not the cause of normal and expected wear and tear. I need help addressing this with TOyota and want to be sure the problem gets fixed before injuries occur. Toyota has multiple bulletins in the NHTSA data for this issue from before and after this issued bulletin demonstrating on ongoing issue. I tried to upload the TSB and the repair documentation but your system is not allowing | Crash: No Fire: No | Unknown |

| Sep 2023 | UNKNOWN OR OTHER | Three weeks ago, I took my vehicle to Fred Haas Toyota Dealer in Spring, TX and they informed me that my driver axle needed replacement. My service advisor has now given me three ETAs on when the part will be delivered. Today, he mentioned that there is a nationwide back order on the part and suspects that many highlanders are experiencing the same problem | Crash: No Fire: No | Unknown |
| Sep 2023 | TIRES | These are Toyo Open Country P245/55 R19 tires that have been on my car from 10/23/2020 to now and have 54,600 miles on them. Remaining tire tread depth on this tire was measured using a machinists rule at 6/32" or 4.5 mm deep. The drivers front tire looked fine on my car during a general pre-inspection I did at 6:45 AM as I loaded the car with our luggage for a 7 day drive trip to Florida (app 920 miles). I will advise that I did not look at this tire in great detail during this check - just quick look to see if anything stood out that I needed to be concerned about for the drive. The drivers side front tire went flat after backing straight down a 60' long driveway. I removed the tire with the car in the street and took it to the tire shop where I bought these tires. The tire shop guys found several cracks about 1/2" long or longer in this one spot in the tire sidewall at the start of the tread. They had no idea why it cracked like that and had reported that they had not seen cracks like that in that location before in any tire. I had them pull the tire off the rim and put a plug/patch in it so I could get the car back up the driveway to repack our Florida luggage in the other car. No other tires show this cracking issue. I will replace the tires on 9/11/2023 with new tires. The tire could have blown out on I-10 at speeds of 70-75 MPH due to the almost immediate loss of air pressure due to the crack. There was absolutely no indication of any issues with this tire (or the other 3 tires) prior to backing down the driveway and the tire going flat. I was blessed that the tire lost pressure quickly just backing down the driveway and not on the Interstate highway. I drive the car - no one else. The tires have not been abused during the period they were installed. I rotate the tires every 10,000 miles. I do car PM on a 6 week schedule to avoid any such auto issues. I had just completed a PM about 1 week prior to this tire issue with all found OK. | Crash: No Fire: No | Unknown |
| Sep 2023 | UNKNOWN OR OTHER,SERVICE BRAKES | This Toyota Highlander XLE 2018 was bought new in 2018. Lately in 8/23 started seeing on the dash a "BRAKE" light that comes on and off while driving. 2 weeks later, starting seeing a warning sign saying "Braking Power Low" and a message underneath saying"STOP in safe place". Took it to Toyota dealer twice so far and they could not duplicate the issue ( maybe they did not drive it for enough time). They said also that no error history was retrieved, even though I had shown them video and pictures of the errors when happened. This warning signs has been happening intermittently after driving ~7-10 miles or 10-20 minutes on the road. I have searched on line and found some similar issues and even a recalls for the same issue on some 2018 models of Toyota, Lexus, and Highlander. They said some cars were recalled but not all. I serched for recall on my Highlander and found none.

| Sep 2023 | STEERING,ELECTRICAL SYSTEM,ENGINE | Driving on I75 at 75mph, while trying to adjust the steering wheel, as soon I unlocked steering wheel lock and put the steering all the way to lowest position it just stalled on highway. Lucky enough I was alone and was able to pull over safely. There is seriously something wrong with steering wheel electrical or ignition system or something with else. | Crash: No Fire: No | Unknown |
| Aug 2023 | AIR BAGS | Was hit in the side in passenger door, which pushed my car off the road and hit a tree head on going approximately 40 mph. NO Airbags deployed anywhere in the car. I took pictures of entire interior and also a video showing no airbag deployment. Police, fire and first responders and completely shocked that no airbags deployed. Injuries occurred, thank fully no life threatening. However had the airbags deployed as they should have, and why we chose to buy this vehicle in the first place, those injuries could have been minimalized. If you need any additional info, please let me know. Toyota needs to be made aware of this. | Crash: Yes Fire: No Injuries: 1 Towed Medical attention | Unknown |
| Aug 2023 | ELECTRICAL SYSTEM,AIR BAGS | S.R.S malfunction error message due to open circuit in the left front door harness. Active DTC (S) B1697 code which is related to lost communication with side airbag sensor LH is present in the vehicle. Toyota is refusing to address the issue because it is not part of a covered warranty and there are no open recall on this issue. This is a safety issue in that in the event of an accident, the airbag will not deploy which could be catastrophic. | Crash: No Fire: No | Unknown |

The contact had the vehicle jumpstarted. The vehicle was taken to the dealer and the contact was informed that the brake booster and the vacuum pump had malfunctioned. The contact was informed that the brake booster, master cylinder, and vacuum pump needed to be replaced. The vehicle was not repaired. The manufacturer was contacted, and a case was filed. The failure mileage was 29,000. | Crash: No Fire: No | 29,000 |
| Jul 2023 | UNKNOWN OR OTHER | I have noticed that the car makes a knocking sound when stopped at signals or in heavy traffic. I have taken my 2018 Highlander LTD many times to the dealer and they cannot hear it nor find anything under the car. This has been going on since I took delivery. The service manager said it might be a bearing going out or a loose bracket (I do not know which bracket he was referring to one as he wasn't sure which bearing). He said just to wait and see if anything else more serious develops...this sounds potentially dangerous to me. The knocking noise still persists to this day. | Crash: No Fire: No | Unknown |
| Jul 2023 | SERVICE BRAKES | While traveling down the Rocky Mountains, we experienced a gradual loss of braking. It took extreme pressure on the brake pedal to slow the vehicle. At this point there were no warning lights. Later down the road, the same thing occured again and a BRAKE warning light illuminated. Traffic was light and the incline was slight which prevented an almost certain accident. We limped the vehicle to the dealer. The diagnosis was a Brake Booster failure. This is a 5 year old vehicle with only 57,000 miles! I have never had a booster failure on any vehicle in my life. This booster should be designed to last the life of the vehicle since it is part of such a critical safety system on this vehicle. The failed component was kept by the dealer. | Crash: No Fire: No | Unknown |
| Jul 2023 | SERVICE BRAKES | 2018 Toyota Highlander braking power low warning light came on twice. Mechanic determined it is the brake vacuum booster pump which can cause the brakes to fail to stop the vehicle. This was a recall on some of the 2018 manufactured Highlanders but not all. Many are now failing like mine. I have had it replaced luckily before a major accident and serious injury. Toyota knows of issues but will not recall without NJTSA direction EVEN THOUGH CRASHES MAY HAPPEN. | Crash: No Fire: No | Unknown |
