Vehicle was purchased new in April 2013. For as long as I have owned the car, the engine has had a loud whining noise when driving 10 -35 mph, always when accelerating. The noise is considerable and noticeable, sounding like a transmission or possible engine problem. Being skeptical of my myself, I have driven 2 friend's Camry with 4 cylinder engines I have also driven a 2013 Toyota rav4 with the exact engine and 6 speed gear transmission. None of these make the loud whining noise my engine makes (1 a 2012 Camry and the other a 2013 Camry model and 1 rav4 2013 model). I have mentioned it 3 times on 3 different service visits to dealer. Each time they write it off as transmission gear shifting with 6 speed auto transmission. I do not buy this due to every car I have driven the engine's are quiet at these speeds and do not make the high whining noise my car makes. Matter of fact, they were considerably quiet to the point you cannot even hardly hear the engine. I know that this is not exactly a safety issue but a great concern in which I am being ignored. Just wanted to see if anyone else has this issue as well. Note that I am a automotive glass parts supplier & electrical engineer and I do not imagine things.

The car engine and RPM go up when the car go down hill or you slow down in traffic at speed 45/35/25 mph. Definitely it happen more often at speed of 25/35 mph with full tank or 3/4 of gas tank. When I'm down hill at speed 30 or more then come to the point you need to slow down to make a turn at 25 mph the RPM when up to at some point the RPM up to 2.5 X 1000. I have notice this issue at my Toyota dealer when my service 10,000 mile and they test the car and said nothing happen to the car. I'm concerning I might end up out of control the car if this issue continues happen and I'll be in the car accident.

I bought a 2013 Toyota Camry from germain Toyota, columbus Ohio less than 24 hours ago on 10/26/2013, this was a Toyota certified used car with 160 point inspection and 3 year/36,000 and 7 year/100,000 powertrain warranty, was hardly 6 months old with only 8,274 miles on it when I took possession. In less than 24 hours back in dayton some major problem appeared while driving, first the engine started making some small noise but no warning indicator came up on the dashboard, later on after about a mile it suddenly and completely stopped while I slowed down for a red traffic light. I turned off the ignition and restarted the car, then it suddenly stopped again while getting on the I-75 highway exit. There were cars behind me and crossing by and it was a very dangerous situation considering it suddenly and completely stopped while driving as I slowed down a little bit. All this happened without any warning indicator on the dashboard, and considering this is a current year 2013 Camry model with Toyota certified and very low mileage this is extremely unsatisfactory and put me and my wife at danger. I'll also try to contact the dealer and Toyota customer service separately, I'm also not sure if Toyota or the dealer had any prior knowledge of the defect or were just careless considering they did a 160 point inspection and sold this as a Toyota certified used car. Considering I bought this less than 24 hours ago, I'll try to return this to the dealer and if there is any hassle I would like to pursue this further in the court. Please contact me if NHTSA would like to test or look at the vehicle.

While driving uphill on I80 in pa our engine suddenly lost power. Warning light flashed and buzzer sounded. We were able to move over a lane and then off road. We were lucky. After shutting off power switch, we were able to start and accelerate normally. We noticed that our hybrid 3013 Camry was then no longer in eco mode. We then figured out what happened. Reaching into the storage compartment, I accidentally touched the ev button which turned off the gas engine. The electric motor was not strong enough alone to keep up a safe speed. We suddenly decelerated and luckily were able to avoid a serious accident.
