2015 Toyota Highlander Engine problems

sufficiently durable to prevent oil leakage under normal operating conditions. The occurrence of this problem at just over 100,000 miles raises concerns about the long-term reliability of this component and whether similar failures affect other vehicles equipped with the same engine. Although the leak was described as seepage or oily residue, it may worsen over time. Depending on its severity and location, leaking oil could contact hot engine or exhaust components, potentially causing smoke or creating a fire hazard. Continued oil loss could also compromise engine lubrication, lead to significant engine damage, or result in unexpected vehicle failure. These are potential safety risks associated with the condition, not claims that a fire or engine failure has already occurred. The oil leak was identified by a Toyota dealership during an inspection. The dealership's diagnosis and related service records may be available for review upon request. Whether the manufacturer has formally investigated or acknowledged this condition as a defect is unknown. I respectfully request that NHTSA review this complaint alongside other reports involving timing chain cover oil leaks in 2015 Toyota Highlanders equipped with the 3.5L V6 engine. I ask the agency to determine whether these reports indicate a recurring premature component failure, whether the condition presents an unreasonable safety risk, and whether further investigation or corrective action is warranted.

diagnostic testing. The contact related the failure to NHTSA Campaign Number: 18E107000 (Electrical System, Visibility); however, the VIN was not included. The manufacturer was not notified of the failure. The failure mileage was approximately 193,000.

I immediately pulled over to the side of the road and exited the vehicle with my young daughter. The smoke continued and the entire front section of the vehicle quickly caught ablaze. Police and the fire department arrived on the scene to assist and extinguish the fire. The vehicle was towed and determined to be a total loss by insurance. Our safety was put at risk because our vehicle spontaneously caught fire with no early warning signs; if we had been driving on a highway or a road without space to quickly stop the vehicle and safely exit, we would have certainly faced injury or possible death given the speed and ferocity with which the fire erupted. After we contacted Toyota several times, they sent an inspector to look at the vehicle, and reported: "The inspector observed extensive fire damage to the engine compartment and interior of the vehicle. The inspector also observed that there was no oil registered on the dipstick. There were no arc marks on the wiring in the engine compartment when inspected. The inspector did not observe any oil leaks when inspected. The battery hold down bracket was in the proper location. The cause of the fire was undetermined, and there was no evidence from the inspection to indicate that this incident was a result of a vehicle defect." Toyota has shown a complete lack of curiousity as to determining what could have caused the fire and has only focused on avoiding liability, thereby putting customer safety at risk.

reached the shoulder and the car came to a stop just as I made it to the shoulder. The whole incident, from the time the first warning light came on until the car completely stopped, lasted about three minutes. Prior to this, there were no warning lights, and I had been driving the car without incident. The car had received all regular maintenance at proper intervals. Mileage was 86,100 at the time. There were five people in the car, including myself, my teenage daughter, her friend, and her friend's parents. We were driving the girls home from a summer camp. We are unharmed -- and possibly alive -- only because I was able to merge across four lanes of traffic and reach the shoulder before the engine completely failed. Just behind us and just ahead of us on this stretch of interstate, there is no shoulder. Semi trucks populate this very busy road. We had to sit on the shoulder for two hours waiting for a tow truck. We are all truly fortunate to be alive and unharmed. The vehicle is in the possession of [[redacted]] Toyota, [[redacted]] . The service department has diagnosed as follows: "Performed diagnostic and found codes P0300, P0301, P0302, P0303, P0306 engine misfire codes. Code P1603 Engine stalls out. P1604 Stability malfunction. Code P1605 Rough idle. Spark plug number 6 is damaged. Check piston with borescope, piston is also damaged." I am being advised to replace the engine at a cost of $8820. Toyota US has been notified. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

has less than 33000 miles on it and has had regular maintenance. This is truly a safety concern at this point and it seems I'm not the only one with this issue according to those reported to the nhtsa.

dealer. I switched off the car at the shop and it wouldnt repeat the problem, no codes have been recorded by the vehicles computer because the check engine light never came on. Toyota and the dealership want to wait until it happens again. Since it happened before, also while it was driving I am uncomfortable as it is a safety concern. I don't want it to happen on a busy highway. I believe the intelligent power module of the car is shorting out and causing the car to go into failsafe mode and shut down creating hazardous driving conditions.

alarm. Smoke started coming out of the front left hood. I shouted for my daughter and her friend to get out of the vehicle. I grabbed my phone and ran to her door to help her and her friend get out. By the time we were running away, flames were coming out of the hood. Within minutes my car was completely engulfed in flames.

the driver side suspension control arm. The contact stated that the subframe needed to be further inspected and replaced. The contact also waited longer than two weeks for the parts to receive the repairs due to the failure. The vehicle was repaired and the contact took the vehicle to another dealer who inspected the frame. The second dealer, a manufacturer's technician, further inspected the vehicle and stated that the subframe was cracked. The technician stated that the contact had the option of receiving a repair of the frame being welded or various parts would need to be removed to replace the subframe, which was an extensive repair. The contact was uncertain of the best course of action to permanently repair the condition. The vin was not available. The approximate failure mileage was 11,562. Updated 06/14/16*lj *tr
