2017 TOYOTA HIGHLANDER Complaints

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.

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.

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!
