Toyota Piston and Ring defect. My 2012 Toyota Highlander engine has defective pistons and rings that have led to excessive oil consumption and the potential for a serious accidents as it causes the engine to lose compression and conk out, all of a sudden, in traffic, and costly repair for us customers with less than 150,000 miles. Piston/ring issue diagnosed by Toyota Dealer in Panama City, Florida. A class Action lawsuit needs to be initiated, immediately, for the 2012 Toyota Highlander. Toyota has already had a Class Action Lawsuit for this same problem in 2014 for their other Toyota models.

The contact owns a 2012 Toyota Highlander. The contact stated that he noticed that the front and rear driver’s side and rear passenger’s side carpet were soaked with water. The contact then stated that he also noticed the water had leaked from the sunroof. The vehicle was taken to an independent mechanic where it was diagnosed that water had entered through the sunroof due to the drain tube being improperly designed. The contact stated that he was concerned because of two visible electrical connectors near the front driver’s side floorboard and possible mold, corrosion, and rust. An undisclosed dealer was notified of the failure and the contact was informed that he would receive a call back but no response was received. The manufacturer was not notified of the failure. The failure mileage was approximately 128,000.

Around 112,500 miles our vehicle's oil pressure light came on. My husband drove it home, and our mechanic told us to tow it to his shop for inspection. The next day I drove it to the shop, which was only a few miles away, and my mechanic informed us that there was "no oil left" inside the engine and that it was a miracle the engine didn't seize on the way. We left it at the shop, a certified Toyota mechanic, overnight for inspection. The next day our mechanic informed us that the piston rings in the engine have failed and oil was burning internally. Every service had been done on this vehicle by a Toyota dealership or a certified mechanic. We were shocked considering the mileage on the vehicle. We have since discovered that the V4 engine in this vehicle was also problematic with Camrys and other Toyotas, but that the recalls were only repaired prior to 60k miles and our vehicle was not apart of that service bulletin, even though it was the same problem and same engine. We could have been on the interstate with our 4 and 6 year old children in the vehicle if the engine seized. This is a tremendous engine issue and we understand that soon the engine will produce smoke that could blow into the vehicle. We have calculated that a quart of oil is being burned every 600 or so miles.

This is the second Highlander Hybrid I've owned that has had the brake actuator and booster assembly fail affecting the functionality of the car's braking system. Replacing these two parts has an absurd price of over 3k at the dealership and other independent hybrid repair shops. My car only has 70k miles on it and I've read this issue applies to almost all other Toyota Hybrids. If most hybrid's brakes will fail eventually, putting at risk owners, why is there not a recall to fix this "not a matter of if, but when" possible life threatening issue?
When turning on the defrost button, the engine shuts off while driving.
I was driving and arrived home and suddenly lost my braking and almost hit my house if I didn't steer the wheel towards my lawn and put on my parking brake it would have been a disaster.

I was driving and arrived home and suddenly lost my braking and almost hit my house if I didn't steer the wheel towards my lawn and put on my parking brake it would have been a disaster. I felt so unsafe that I had my vehicle towed for repair and had to replace the brake master cylinder. Two weeks later, we went on a family trip and parked my vehicle with my family and it was on a slight slope and went to put on the parking brake and it was still slightly moving forward only to put my vehicle in reverse QUICKLY in order in NOT DRIVE INTO A LAKE WITH MY FAMILY IN THE vehicle!!! I have just read the complaints and this is an ongoing problem since 2011 and I am quite SHOCKED that this is NOT ON RECALL!!! My wife has a Prius V 2013 and have not had any problems at all, BUT has a recall on a Brake Hydro-Boost pump fail for her vehicle, BUT nothing is wrong with her brakes, ONLY THE 2012 TOYOTA HIGHLANDER!!! Please let me know what Toyota needs to do to get this this fixed!!! I know there are probably more that no one is reporting this and I guess there must be a fatality in order for Toyota to fix this problem!!!!
The Brake Hydro-Boost pump failed while driving on I-75. Subsequently almost all braking was lost on the vehicle. I have researched similar failures on the same model brake pump assemblies, and feel that this is a very unsafe failure condition for the vehicle.

The Brake Hydro-Boost pump failed while driving on I-75. Subsequently almost all braking was lost on the vehicle. I have researched similar failures on the same model brake pump assemblies, and feel that this is a very unsafe failure condition for the vehicle. The repair cost for this failure is exorbitant given the rate of failure which seems to exist with this make/model. Luckily I was driving the vehicle at the time and had the presence of mind to allow the vehicle to roll to a stop using engine braking. This failure could have caused a multiple fatality accident in may opinion. Toyota is negligent in their care regarding theses failures.

On December 29, 2021, while backing up my 2012 Toyota Highlander accelerated at speed that I was unable to control. One car that was packed in the driveway was damaged beyond repair. An office building where I was working was damaged and has been accessed with a loss of over $100,000. I contacted Toyota after knowing that there was a recall regarding unintended acceleration in some Toyota cars. Toyota sent an inspection team to Geico Insurance company which had taken over possession of the car. The inspection team and the Toyota representative assured me a final report would be sent to me within a month after the inspection had been completed but even up to this moment Toyota has not responded to my email requesting for the report. You can reach out to Toyota and reference File # 220105001224. For the six years I owned the car, i have never been informed of any recall. My car was regularly serviced by Toyota Ourisman Chantilly and Ourisman Toyota Fairfax.

2EA18006 · Steering Column Separation
Opened Nov 16, 2018 · Closed Apr 2, 2024
Status: closed (inferred from source dates) · Steering; Steering:column
On November 16, 2018, the Office of Defects Investigation (ODI) opened an Engineering Analysis (EA18-006) as an upgrade to a Preliminary Evaluation (PE18-005). The investigation focused on allegations of steering wheel separation from the lower steering column after using the tilt and/or telescoping mechanism. Given the separation occurring when operating the tilt and/or telescoping function and failure of both shear capsules to maintain the lower steering column mounting position, potential for shear capsule damage in the known failures due to collisions, the overall low rate of occurrence, and the updated manufacturer documentation, this investigation is closed. The closing of this investigation does not constitute a finding by NHTSA that no safety-related defect exists. The agency reserves right to take further action if warranted by the circumstances. A detailed summary of the investigation is attached to this closing resume. To review the ODI reports cited in the Closing Resume ODI Report Identification Number document, go to NHTSA.gov.

PE18005 · Upper Steering Column Separation

Status: closed (inferred from source dates) · Steering; Steering:column
On May 4, 2018, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE18-005 to investigate three allegations of steering column separation for Model Year (MY) 2008 through 2013 Toyota Highlander vehicles. Two (2) of the 3 complaints were received by ODI in April 2018 and occurred while the vehicle was in motion. Since opening PE18-005, one (1) additional VOQ involving steering column separation has been received. This incident occurred while the vehicle was stationary.As part of PE18-005, ODI examined the field data, warranty data, and relevant technical information submitted by Toyota in response to the PE18-005 information request letter. Ten (10) additional incidents of steering column separation were identified. Four (4) of these instances occurred while driving. During PE18-005, ODI confirmed that the steering columns in the subject vehicles are equipped with breakaway capsules that are designed to collapse/shear during certain types of vehicle collisions. This design feature aims to reduce driver injury severity from impact with the steering wheel in frontal vehicle collisions. There is no direct method for detecting when the capsules in the subject vehicles have sheared. If the driver operates the tilt/telescoping feature after the breakaway capsules have separated, the steering column may drop out of position and could subsequently detach entirely from the rest of the steering assembly. Loss of steering while driving may cause a loss of vehicle control, which could lead to a vehicle crash.To date, ODI has identified 14 incidents involving complete steering column separation, 6 of which occurred while driving. One of these incidents involved a minor crash. Additionally, there have been 16 events where the steering column dropped from the dashboard mounting brackets, but column separation did not occur. Four of these incidents happened while driving. Of these 30 total separation/drop incidents, 5 of the vehicles have evidence of minor collision repairs months or years prior to the steering column failure.This investigation has been upgraded an to Engineering Analysis (EA18-006) in order to 1) conduct a more detailed analysis of the conditions that may cause the steering column breakaway capsules to separate and 2) assess factors that may contribute to the problem of failing to detect and repair breakaway capsules after they have separated. Toyota has recently revised their repair manual and issued a Collision Repair Information Bulletin to help address the second concern.The VOQs associated with this investigation can be viewed at www.NHTSA.gov under the following ODI complaint numbers: 11141761, 11083623, 11083280, 10888043.
