Selected complaints filed with NHTSA by 2010 Toyota Camry owners, lightly cleaned up (personal details are redacted by NHTSA).
Odometer Fraud. The contact owns a 2010 Toyota Camry. It was discovered that there was a mileage discrepancy. The vehicle was a private sale. At the time of the purchase, the mileage was 138,000; however, as per a Carfax report, it was discovered that the mileage was approximately 259,000.
On February 2, 2010 I was entering my garage and slowly drove in, I then placed my foot on the brake to stop, I then opened the drivers side door slightly as I was about to place the vehicle in park a short revving of the engine began, right before I placed the shifter into park the vehicle jumped into reverse and began to accelerate backwards,causing damage to the drivers side door which flew open due to the reverse acceleration, the wall in my garage ,the garage railing , the side panel of the garage were all damaged as a result. I then slammed on the brakes and the parking brakes, placed the shifter in neutral and then turned off the engine, I then called the Toyota corporation and explained the event to them. Their process was slow and not considerate to my needs as a consumer. …
The red indicator light in my dash display came on when I started the car and continued while I was driving, so I took it to a mechanic. My alternator needs replacement, which is very disappointing because the car only has 84,000 miles on it and has been very well maintained and serviced regularly. I purchased a new battery about 2 months ago, and the alternator replacement quote from the Toyota dealership where my family purchased the car new is quoting $1,245 for a new alternator (parts & labor). An internet search LED me to find that this is happening to quite a few owners of this era of Toyota. I called Toyota customer service and was informed that there is no recall or any type of assistance available to cover the cost of this very expensive and premature repair. …
On 2 occasions while driving at speed (65-70 MPH) in traffic on a major interstate, my car lost power (it did not cut off--only lost power). After working my way off of the interstate hwy., I was able to use a code reader and found that diagnostic trouble code p2112 had been set (throttle actuator control system-stuck closed). After erasing the DTC the car ran OK. This has happened twice--once on 02/16/2017 (mileage 75,465) and a second time on 04/10/2017 (mileage 75,829). Following the instructions in Toyota's service manual for this particular vehicle, I checked the resistance of the throttle actuator on the throttle body and found it was well within specifications--measured 4 ohms and spec is 0.3-100 ohms). In my opinion, losing power in heavy traffic on a major interstate is a very hazardous situation.
The instrument cluster went black when driving in the highway out of town. And later the engine was turned off. Restarted the car and drove to be checked at a dealer who said everything should be fine except for the instrument cluster. Restarted the car and the instrument cluster worked well this time. Two days later, the instrument cluster turned on all of warning lights and then went black again, at the same time, the car lost power and I couldn't speed it up. Pull over and restarted it, everything turned to be OK. So, I sent it the local dealer who replaced the instrument cluster. I keep the broken instrument cluster in case for need of further investigation.
Both the driver's side and passenger's side lock controls fail to lock and unlock both the driver's side and rear driver's side doors. Occasionally, depending on the temperature and humidity, the rear driver's side door will lock and unlock. It is a similar problem associated with the window/ lock control recall for 2007 and 2009 Toyota camrys. It almost seems as though there is a faulty wire connection. This occurs at all times, no matter whether the car is in motion or not.
My airbag light turned on in my car. I took it to the dealer and they said that water was leaking from the HVAC system onto the airbag control unit and shorting it out. This was because the drain from the HVAC system was clogged and condensed water was not draining out onto the ground as designed. Instead, it built up and then leaked onto the airbag control unit. This exact problem was recalled on other model years of Toyota camrys.
My fuel gauge always show a full tank of gas even when tank is empty, and when I turn the ignition key off, fuel gauge still shows full. I can't tell how much gas is in my tank, and this has result me without gas on a busy highway, it is really a safety hazard. Please recall.
This car has required 6 sets of tires in less than 90,0000 miles. The driver's side window will roll down when pressing the button to roll it up. This has been going on since the first oil change. The air conditioner occasionally switches itself from recycled to fresh air while driving for unknown reasons. Sensor in passenger seat malfunctions causing random alarm about seatbelt when no one is seated there. The dashboard became sticky to the touch, and cloth would stick to it when attempting to wipe it clean. The dashboard then developed several deep cracks, running erratically ly from front to back. In places around trim pieces, dashboard plastic has flaked away. Plastic on the top of the console's lid has chipped and flaked away, and cracks have developed around it. Paint on trim of console has bubbled up and ruined the finish in console drink holder lid. …
My 2010 Camry has been to the dealer a few times. Know one seems to be able to duplicate the acceleration surge I'm experiencing. I contacted Toyota directly. They sent me to different dealer. Dealer had it for a day and said the same thing "can't duplicate" I think they have all been schooled to say this. I had the service manager ride with me and told him to watch the RPM dial when I go to stop. He saw the RPM dial move up to almost 2000 when I hit the brake. He had me drive another 2010 Camry and it did the same thing. I had a 98 avalon and a 03 Camry that did not do this. He explained to me that this is the way these new cars down sift and it's different than the older Toyota's. He assured me that my car is safe and I have nothing to worry about. After reading all of the other complaints here I'm not 100% sold that this is normal down sifting. …
