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.

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.
When turning on the defrost button, the engine shuts off while driving.

The contact owns a 2012 Toyota Highlander. The contact stated while driving 60 MPH, the vehicle suddenly loss motive power while depressing the accelerator pedal. The contact pulled over and attempted to restart the vehicle; however, the vehicle failed to restart. There were several unknown warning lights illuminated. The vehicle was towed to an independent mechanic to be diagnosed. The contact was informed that the timing chain fractured and that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 120,000.
WELL BEFORE MY OIL CHANGES ARE DUE, MY VEHICLE NEEDS MORE OIL. THERE ARE NO APPARENT EXTERIOR LEAKS BUT THE OIL HAS TO BE LEAKING SOMEWHERE OR BURNING AWAY THROUGH THE EXHAUST.
CAR HAS OVER 117,000 MILES AND IS EXCESSIVELY CONSUMING OIL. THERE IS NO SIGN OF LEAKS ANYWHERE.

CAR HAS OVER 117,000 MILES AND IS EXCESSIVELY CONSUMING OIL. THERE IS NO SIGN OF LEAKS ANYWHERE. I DO NOT GET ANY WARNING ANYWHERE ABOUT LOW OIL, ALL I SEE IS A SMALL MESSAGE THAT SOMETIMES BLINKS INDICATING 'OIL PRESSURE'. OIL IS NOT LASTING 1000 MILES. I THOUGHT MAYBE THE OIL WAS NOT PROPERLY FILLED BUT AFTER A SECOND OIL CHANGE, SAME HAPPENED, OIL EMPTY WITH LESS THAN 1000 MILES AFTER AN OIL CHANGE. CAR HAS BEEN ALWAYS KEPT WITH ALL RECOMMENDED MAINTENANCE AND ALL OIL CHANGES HAVE BEEN DONE EVERY 5,000 AS RECOMMENDED BY TOYOTA. HAVE NEVER BEEN IN ANY ACCIDENT THAT COULD CAUSE ANY ENGINE PROBLEM, SEEMS THIS IS A FACTORY DEFECT. IN THE ELECTRICAL PART, POWER BACK DOOR DOES NOT CLOSE/OPEN, THERE IS A RECALL FOR THAT BUT NO DEALERS IN MY AREA WILL FIX IT BECAUSE ONE OF THE PARTS THAT IS INSIDE THAT MOTOR IS NOT LISTED IN THE RECALL SPECS AND DEALERS WILL NOT FIX UNLESS I PAY. I TOOK THE CAR TO THE DEALER ABOUT 2 YEARS AGO. THIS REFERS TO THE WARRANTY ENHANCEMENT LETTER ZG4.

THE "MAINTENANCE REQUIRED " LIGHT CAME ON AND I STARTED NOTICING A STRANGE NOISE AS I STARTED THE CAR EVERY MORNING AND AGAIN AS I ACCELERATED. I CALLED AND MADE AN APPOINTMENT WITH THE DEALER I PURCHASED THE VEHICLE. THE SERVICE ATTENDANT REPORTED TO ME THAT THE OIL LEVEL WAS BARELY VISIBLE ON THE DIP STICK. THE DEALER SHIP CONDUCTED AN "OIL PRESSURE TEST" AND DID NOT DISCOVER ANY LEAKS. SO THEY ARE CONDUCTING AN "OIL CONSUMPTION" TEST AND I AM TO RETURN TO THE DEALERSHIP AFTER 1100 MILE TO DETERMINE THE AMOUNT OF OIL CONSUMED ON MY VEHICLE.

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
Opened May 4, 2018 · Closed Nov 20, 2018
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.
