The contact owns a 2013 Toyota Highlander. The contact stated that on several occasions, the vehicle exhibited unintended acceleration. Additionally, the vehicle would vibrate excessively when stationary with the engine on. The vibrations would cause ear pain to the contact. The vehicle was not diagnosed or repaired. The manufacturer was notified and no solution was offered. The failure mileage was 11,000.

The vehicle did not alert to any engine and/or vehicle problem (no caution light, no engine light, etc.) the driver happened to look down at the fuel tank and noticed that the temperature gauge exceed the measuring mark (over the red zone) and was still running. The driver immediately went to a safe place. Towed to the dealership. Dealership informs that a "small rock or road debris" traveled through the front grill and punctured the radiator. After researching why the radiator is not covered under the warranty on brand new vehicle under this road debris, I read over 30 reported cases in not only the Toyota Highlander, Toyota Tundra, and Toyota corolla as their is no protection to the front portion of the radiator and/or condenser. Would have caused engine fire, do not understand why there were no safety lights and or indicators something was wrong with vehicle.

On Thursday, April 3, 2013. I stopped at an intersection and when I tried to accelerate there was no response. I thought the engine had died. There were no lights on instrument panel. I pressed accelerator again and it jerked and took off. I have experienced hesitations several times (10-12). I bought the Highlander 2013 in July 2013.

I bought a 2013 Toyota Highlander in October 2012 and never noticed any problem until early in 2014. When I try to accelerate on a small incline, the accelerator would not respond. It acted as if I am not pressing the gas pedal. I am not talking about going to the mountains but just a small incline when I drive home from work everyday. I took it into the dealer in March 2014 and they responded same as other people on this website, no errors on the diagnostic machine and no posting from Toyota. They advised me to put in premium fuel and I did but that did not make a difference. Very disappointing from a Toyota with a V6 engine. The dealer also tries to say it is due to cvt transmission. However, I have a Subaru with cvt as well and that car can accelerate uphill when needed. I have had a Toyota Celica, tercel, and a Toyota truck in my life and none had this type of problems.

I bought a new 2013 Highlander December 28, 2013 from tom wood Toyota dealership. When I was driving home December 28-31, 2013 click, click, squeaking noise, brakes slipping, dragging, vibrating and a tremendous pulsating against my foot when I stop. When I tried to stop the Highlander the vehicle jumped forward. January 2, 2014 a burnt odor coming through the heater vents, rattling in the right front door, gush sound coming from the brakes, there is also another sound coming from the brakes that I can not identify. I am wondering if a fire is trying to start, because of the burnt odor.

Occasional throttle no response when trying to accelerate moderately from a stop, or from a very low speed (I.e.-coasting around a 90 degree turn with the engine at idle speed.) I then push heavily on the accelerator pedal, and it revs up, downshifts, and races ahead. It is dangerous, in traffic. I have brought it to the dealer twice, and they cannot reproduce the problem. Two so called factory reps rode around with me the second time, with a computer connected. Diagnostics shows no error codes.

At totally random times, after a few miles of driving or from a slow speed, vehicle hesitates when accelerating. Most annoying and dangerous is the way it doesn't respond to the accelerator for a few seconds after stopping at a stop sign or stop light or when going slowly as in entering the freeway. Took vehicle to Toyota dealership and of course vehicle ran fine for the time they drove it. Tech checked for any trouble codes and none were found. This problem seems like an accident waiting to happen. Have gotten nothing but the run-around and denial from the national Toyota "case manager". (at first I thought this hesitation occurred because the vehicle was new, but after 5,000 miles, I am still experiencing the same issue at random times.)

When turning left out of my neighborhood I slowed down and then tried to return to speed but the vehicle hesitated then suddenly jerked up to the desired speed. One other time on an interstate I had to slow down behind a truck and then when I tried to accelerate back to speed in the passing lane the car hesitated for several seconds and again accelerated rapidly (cars in the passing lane had to brake quickly. I could describe other times but the same thing (the hesitation and then the extremely rapid acceleration) I have taken it do the dealer but they said that they could not find anything.

- Auburn, AL, USA

The vehicle has a hesitation or lack of acceleration problem. It occurs from a stopped position or a moving state. I have had it to the local Toyota dealer 5 times and they have not been able to find the problem. They were able to duplicate the problem. They have been in touch with Toyota but they say no problems exist, which is what I have come to expect from Toyota corporate. My wife was almost in an accident on the interstate yesterday, 08/28/2013. I would estimate that the problem has occurred at least 10 times since we purchased the vehicle in July. This is a safety issue. Thank you in advance for your help on this concern. Also, the dealership is going to give us a loaner today and possibly just let us return the vehicle. They have been great, palmierro Toyota.

At totally random times, after a few miles of driving or 100 miles, vehicle hesitates when accelerating. Most annoying and dangerous is the way it doesn't respond to the accelerator for a few seconds after stopping at a stop sign or stop light. Took vehicle to Toyota dealership and of course vehicle ran fine for the 4 miles they drove it. Tech checked for any trouble codes and none were found. This seems like a rear-end accident waiting to happen. For ten days we have gotten nothing but the run-around from the national Toyota "case manager". (at first we thought this hesitation occurred because the vehicle was new, but after 8,000 miles, we are still experiencing the same issue.)

- Stillwater, OK, USA

Vehicle hesitates when accelerating. Does not happen all the time, when trying to get vehicle up to highway speed will depress gas pedal and nothing will happen for 3-4 seconds, then all of a sudden vehicle will speed up. This only started to happen after 1300 miles. Took vehicle to Toyota dealership and of course vehicle ran fine, tech. Checked for any trouble codes and none were found. Also since this started to happen my gas mileage has dropped from 18 miles a gallon to 15 miles a gallon.
