On August 10th 2018, I was driving my 2017 Highlander with 17,000 miles on a major highway in California when I accelerated hard to pass other vehicles. Suddenly the Highlander lost all power with all the bells and whistles sounding. The orange triangular warning/check engine lights came on with the all wheel drive system failure flashing needing immediate service. I was able the get to the side of the highway without getting killed and turned the car off. After a minute I was able to restart the car and all the warning lights reset. This was the second time this happened. First time this happened the Highlander had only 4,000 miles on it and was under the same circumstances. I was trying to pass. When I took it to the dealership in reno nv they said all the error codes were not captured and they had not heard of this issue despite many complaints on the internet as well as this site? I was told there was nothing they could do without an error code. They suggested the next time it happens, do not restart the car and have it towed the a dealership to try and recapture an error code. I filed a claim with Toyota corp but they lead me to think that they don't investigate incidents like this unless there are numerous complaints. I have advised my family of this dangerous condition with the Highlander and if any one gets hurt or killed please sue the heck out of them. This is a very dangerous symptom with the Highlander that is going to get somebody killed and Toyota doesn't seem to care.

I recently noticed a rattling sound out of the engine area that occurs intermittently. It typically occurs after the vehicle sits for a couple hours after it has been driven up to operating temperature. The sound happens for less than 2 seconds. The Toyota dealer in our area diagnosed the issue as a failure of the intake cam gear per Toyota technical service bulletin 0094-09. The service advisor stated that if the issue is left unaddressed, it could lead to complete engine failure. He also stated that the updated cam gear made by Toyota does not fit the existing camshaft. This means that all 4 cam gears and two camshafts would have to be replaced which dramatically increases the labor and parts costs. I was given the following quote for the repair: part's $3748. 00 labor $2137. 00 tax $348. 00 total $6233. 00 I took the vehicle to another Toyota to confirm the diagnosis and they confirmed the issue and quoted me at a similar price to do the repair. Message boards all across the internet describe a similar phenomenon. After discussing the matter with Toyota corporate, they agreed to cover 50% of the parts cost, but I believe this to be unfair because their updated part intrinsically and dramatically increases the labor and parts costs. Even though only one cam gear failed, the replacement of all 4 cam gears is now necessary.

Vehicle makes a very noticeable, irritating whine or whistle noise when accelerating at 40mph. Stops when gas pedal is released. Very constant and annoying. Did not happen when car was first purchased. Have been told by Toyota that it was the transfer case, which they replaced. Did not fix the problem. Now they tell me it is normal. Test drove another vehicle from their lot of the same exact year, make, model. No noise at all. This is not normal. Toyota knows about the problem, but they are denying it. Other Toyota vehicles (I. E. Rav4, tundra) had/have the same problem. Forums tell me it is the transmission. Waiting on appointment for a field tech from Toyota to examine it.
