The contact owns a 2016 Toyota Highlander. The contact stated that while driving at various speeds, the vehicle would shut-off without warning. The contact would be able to restart the vehicle a few minutes after the failure. The contact had taken the vehicle to an unknown dealer. The dealer attempted to charge him a diagnostic fee and the contact refused. The manufacturer had been notified of the failure and they sided with the dealer and insisted that he pay a diagnostic fee to have the vehicle serviced. The vehicle was not repaired. The failure mileage was unknown.

Engine is making a audible knocking sound that increases with engine RPM. The sound is emitting from the bottom right hand side of the engine (underneath/to the right of the oil pan on the side nearest to the pulleys and serpentine belt). I have reported this issue to reliable Toyota in springfield Missouri. Dealer claims the sound is normal even after video evidence was provided. However, I have not heard a knocking sound coming from other Highlanders. A non dealer mechanic was consulted and he heard to noise and advised my to return to the dealer so they may solve the issue under warranty,

Whenever the weather is colder like 35 degrees or lower I am having issues starting the vehicle. The dealer already changed the battery but it did not help. I had the vehicle by the dealer for 10 days but they couldn't figure it out. In this time I had to pay out of pocket for rental and other expenses. Yesterday it took me 45 minutes until I was able to start the vehicle. I spoke to Toyota and they are not very helpful.

Occasionally, at a stop sign/intersection or entering a highway if I have come to a full stop before proceeding the car will stall. I pressed on the accelerator and nothing happens. My wife and I have found ourselves in this predicament several times now and it is only getting worse. This scenario is very dangerous for several reasons, but the most important one is that my family has been inside the car when this has happened. We have had several scares now, because the car stalled on us as we were entering the highway. I have spoken to the dealer about this over the phone and both times that the car has been serviced. After they test drove the vehicle, I was told that this was normal behavior due to a delay between the computer and the accelerator throttle. Additionally, I was also told that Toyota is aware of this, but has not addressed the problem. This is extremely upsetting because my family is now at risk due to a computer malfunction. I urge the NHTSA to please look into this matter as more and more people based on internet searches are dealing with this same issue. I own a 2005 Highlander with 105000 miles and this has never happened. You would think that a 2016 model with all of its safety features and enhancements would be a pleasant driving experience? but, now that I owned the car for almost 8 months I am second guessing myself whether this was the right purchase. Once, again I urge the NHTSA to look into this and to anyone else out there that is experiencing the same issue, please speak up so that both Toyota and the NHTSA address this problem as soon as possible.

My car engine started on its own after being turned off. I went shopping at walmart and parked my 2016 Toyota Highlander xle in the parking lot. I put the car in park and pushed the engine start/stop button to turn off the car. My family and I exited the car and I used the keyless entry pad to lock the doors. We shopped for approximately 45 min. When we returned to the car, I used the keyless entry pad to unlock the doors so I could put our purchases in the trunk. As I got close to the vehicle I heard an engine running, but thought it was the car next to us. I bent down and listened under the front end of my Highlander and to my surprise, I realized my car engine was running. When I opened the driver side door and looked at the dashboard, I noticed a small triangular yellow caution light was flashing but I don't remember what the message said other than caution. If my car randomly starts on its own while its in a garage, it could cause toxic fumes to fill my garage if left on long enough, and could cause harm or death to someone who breathes it in. After reading about the brake/hydraulic recall on some 2015-2016 Highlanders, coupled with the recent issue I had at walmart, I am nervous about driving my car. I wish I had read about these issue before buying my car 30 days ago. I thought I had done my homework and read several websites before buying the car, but I will read recall reports before buying a car from now on.
