2019 Toyota Highlander

Was stuck in traffic on a highway for about 25 minutes going 0 miles per hour because of an accident about 5 miles away. Then the traffic started to clear and began driving on the road again. About five minutes later, the vehicle lost full drive abilities and the check engine light came on, traction control light on, brake light was on, ABS light was on, stability control warning light on, and then on the info screen the vehicle stated, "Hybrid System Malfunction Stop in a Safe Place, See Owner's Manual", screen then showed within 2-seconds, "Pre-Collision System Malfunction Visit Your Dealer", then in about 2 additional seconds later the info screen stated, "Check Engine Visit Your Dealer", then most every waring light turned on, and there was no power for drive with either hybrid or gasoline engine. The vehicle basically came to a sudden halt in the middle of traffic with steering wheel locked and no control. Had to get police involved and a tow to get off the road. Had vehicle towed to a local toyota dealership and they do not open until Monday at 9am. This incident occurred on Saturday around 3pm.

Experience "dead zones" in accelerator pedal movement. Experience "no acceleration" with first 1-2 inches of travel from idle position. This is constant and does not vary noticibly with speed. I was driving in an suburban shopping area in York PA with three lanes of travel in each direction. I intended to move from the laft hand lane to the center lane. I indicated my intentions and waited for an opening. I was travelling about 35-40mph. When an opening came along, I steered into the indended lane, but depressing the accelerator to increase my speed, no acceleration occurred. I then panicked and depressed the pedal quicker, and the ensuing acceleration nearly catapaulted me into the semi truck in the center lane ahead of me. I missed the truck by inches. I have had this issue evaluated at Bennett Toyota in Lebanon PA, and the Lancaster Toyota, the dealer who sold me the vehicle in May of 2023, is aware of the issue. Bennett Toyota service department tried to fix the issue by replacing the brake switch. That did not alleviate the problem. I have had several other instances when pulling into traffic when the delayed acceleration caused me issues but no accidents. I believe this issue is related to the selectable "snow" driving function. I think the system is somehow stuck in the "snow" mode at all times. I may have substantiated this today when I experimented with the "snow" function while driving at about 45 mph. When I select the "snow" mode while driving, the accelerator "dead zone" actually gets worse. Bennett Toyota Service response is "it drives like any other Highlander". If that is so - this is truly a huge issue with "drive by wire" tachnology...!!! As a note, at Bennett Toyota I did drive a 2019 Highlander privately owned by the service manager and it did indeed have the dead zone in the acelerator - a fact that the service manager admitted to me verbally. I have read many instances of this issue in chats online.

Vehicle check engine turned on to check AWD system after about 2 days when filling with gas the engine wouldn't start and had Low brake power message on dashboard. Checked code and got P0171 and P0174 which mean engine's air/fuel mixture becomes too lean for the Engine Control Module (ECM) to correct within its normal operating range there are many posts and threads about same issue on highlanders as old as 2017 please look into this issue that could potentially cause a hazard. will take vehicle in for inspection 06/13/23 at Toyota of Naperville

I went out into my garage 3:30 in the morning and heard a motor running very faintly tried tracking down the noise finally located under the car at the rear. It was the fuel pump running. I went in. got my key started the vehicle let it run about a half a minute shut it off. The noise was gone. I’m worried about this pump running for hours or possibly days then catching the car on fire the garage and the house I know there have been issues. With fuel pumps in these Toyotas, but I haven’t found this particular problem online. Possibly there may be a problem with the fuel pump relay?

I have had my vehicle for a little over 3 years, with about 35K miles on it. At first, I realized my vehicle jerked a bit, but I dismissed it because it never stopped. However, I did notice that my battery was dying quickly. I was changed once by the dealership because they said the battery was defective. After they changed that battery, the next battery also went bad. While driving with my children and mother, my vehicle began sputtering and a message that said, "Check Engine Reduced engine power" came on along with "Traction Control turned off" and my engine light. My vehicle barely accelerated as I was trying to cross the intersection thankfully I managed to get out of the way of oncoming vehicles. Somehow, the vehicle ran smoothly after I turned it off and turned it back. After that issue, I then experienced an error message in reference to the Start/Stop system along with the check engine light. That issue also cleared when I turned my vehicle on and off. I then experienced another power loss issue, at which time I traveled to my local Toyota dealership but they were unable to help me then due to a battery issue. The issue then cleared itself somehow again; however, the issue came back the next day. I managed to get my vehicle to the side of the roadway at which time the vehicle stalled. I tried starting the vehicle again; however, it would not turn over. After being on the roadside for about 2 to 3 hours, I tried starting my vehicle again, and it drove fine until I reached the dealership. My vehicle was placed on a machine where they received the code for a fuel rail issue along with a misfire. I was then advised that this issue is not covered under warranty. I was also told that the problem would cost me over 4K for the part which does not include labor. I have been doing my research since and I now find that there is a recall on my vehicle.

Temporary Loss off Power: After driving about 100 miles we stopped for a 15 minute break. Afterwards I started the car and to my surprise the engine was running but I had no power. I was able to coast down a slight grade to avoid other vehicles in the parking lot. I stopped the car, put it in Park (P), put it back in Drive (D) and was able to drive as before. We purchased this vehicle in September of 2018. It has slightly over 14K miles. This has happened at least once before.

When running, after stopping at a stop sign, the car hesitates to go, kind of sputters. When turning the car on, the lights on the dash flicker and now the car won’t start. On days prior, you would turn the car key, but the car wouldn’t start on the first time. It sounded like it wouldn’t turn all the way on, like the battery died. I didn’t leave the radio on or anything that would warrant that.My safety was put at risk because I work in healthcare and get off work at midnight so if I broke down or stalled in traffic, this could cause an accident.
