2016 Toyota Highlander Engine Problems

“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.”

“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,”

“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. …”

“Whistling/squeaking noise from engine when turned off after driving. Took a video and showed dealer who thought it was unusual but no diagnosis on multiple visits.”

“The water pump on my 2016 Toyota Highlander XLE disintegrated while I was driving in heavy traffic. The pulley came loose from the water pump shaft. I have the water pump. Our safety was at risk because this happen in heavy traffic and it could have effected my control of the vehicle if it had came off completely. The pulley was wedge between the wheel well and fame. I sent a claim to Toyota and it was rejected due to the vehicle be out of warranty. I'm saying this is a manufacturing defect. No warning before it happen.”
