Toyota Camry Hybrid Engine Problems



  • I will bring this response to the attention of the dealership mechanic. I have brought the above described problem to their attention already, but after running tests, they could not find anything wrong with the car. The mileage is about as claimed. I have noticed from other posts, that others are getting frustrated with bringing their cars to the dealership mechanics for the engine check light going on and have been told no problems were found. As I stated, the light appears related to the gas cap loosening. Having it under warranty doesn't provide a lot of solace if your car is spending a great amount of time in the shop only to be told no problems can be detected. I brought my car in again today and gave the mechanic a detailed description of my observation as above. The head mechanic did call Toyota tech and was told that there are many other similar complaints. The end result is that they are ordering a new fuel filler neck and gas cap. It'll take a month to get the parts so I'll have to wait to see if this resolves the problem. But then again the weather may be cooler and it may not show up until it's hot again. It does also seem somehow related to the heat.
  • I had the same problem on my 2009 Toyota Camry Hybrid. The gas cap didn't tighten correctly, and I got that strong gasoline smell and the Check Engine light went on and stayed on.
    I took it to the dealer and they turned off the CE light, tightened the gas cap and promised to order me a new gas cap. It hasn't arrived yet but I have had no more problems with the old one.
  • I have had the same problems with my 2009 TCH.
    First, I had the strong gas smell (and this was outside in the driveway!) and a small amount of gas on the driveway behind the left rear tire. Brought it in to the dealer, and they could not find anything wrong. The check engine light did not come on this time.
    Then several weeks later the check engine light came on. The gas cap seemed loose, so we were sure that was the problem. We drove the car quite a bit and had several fill-ups before having the light reset during the next regular service. They confirmed it was a loose gas cap that caused the light to come on.
    Yesterday the light came on again, and again the gas cap seemed like it was not tightened properly. We have been hyper vigilant about paying attention to the clicking sound when filling up ever since the first incident with the gas that leaked out, and we never top off the tank. Not to mention we have both been successfully tightening gas caps on various cars for quite a few years now!
    I am annoyed at having to go into the dealer again to have them reset the light and tell me they don't find any problems. I hope Toyota will acknowledge that there is an issue here and figure out how to fix it. I'd be interested in hearing whether a new gas cap fixes this problem for anyone.
  • Our 2009 Camry Hybrid with 90,000 miles (it's a taxi) completely froze up while driving on the freeway. We had it towed in and the mechanic at Toyota quickly said it was due to "poor maintenance" despite the fact that we regularly had the oil changed and any other routine repair. There were metal shavings in the engine and we're going to have to replace it at great cost. The timing chain was intact. Does any one have any ideas on what might have caused this? Reading other problems posted for this model, could they have caused the engine failure eventually? It's hard to compare to other posted problems because few 2009's have such high mileage. I'd be grateful for any ideas.

    Since the car is a commercial vehicle, it is not covered under warranty, so I don't know why the dealer would be so quick to try and make the failure your fault. Has there been any identification of the failure? What failed? The engine seized (oil pump failure?) ? ECU failed and shut down the system? Battery system failure?

    A lot more info is required before anyone can make a knowledgeable reply.

    Please keep us posted.
  • How often was the oil changed and what grade oil was used?
  • my 2007 hybrid camry had to hybrid system malfunction light come on. It worked on battery power had to pull off the road and by turning the car off and on car worked normal but engine light and malfunction warning stayed on. 1000 miles prior to this I had taken it to the dealer for an oil change. At that time they recommended, strongly, a fuel injection cleaning , insisting it was recommended by toyota. I did not recall it in the manual and with modern engines and fuel it is a useless recommendation.
    They told my wife the fuel injectors were "gummed up". When I called back they said the fuel injection cleaning would help since they got a throttle body error code. the engine has never had a problem, no acceleration or running issues. ran great after restarting the car.
    what do you think?
    they cleared the codes , car runs fine , no error codes after test drive.
    I asked them to flash the computer but they did not understand how to do this
  • Take your car to another Dealer or mechanic!!!!!!!!!!!! The throttle body is the part of the air intake system that controls the amount of air flowing into the engine, in response to driver accelerator pedal input. This does not explain why you had a hybrid malfunction light and there should have been a code recorded on the cars computer for the dealer to diagnose. How many miles are on the car?
  • thank you for the info. 56,000 miles now
  • 56000 miles I had just taken it in at 55000 miles when they tried to sell the fuel injector cleaning! of course I declined. now they want to sell it again to help the throttle body error code they said they got.
  • got 2 error codes
    p2103 and p2111
  • P2103 throttle activator control motor circuit high
    p2111 throttle activator control system stuck open
    look up"electronic throttle control" on wikipedia for a detailed explaination on how this part works
  • I have a 2005 Prius with 142,000 miles on it. About a week ago I got a check engine light and brought it to my local dealership here in Annapolis. The error code is P0505. The recommended a host of work that did not make sense to me. I then took it to a local mechanic and he pulled the codes again and one came up that the hybrid system was not communicating. He cleaned the throttle body and then the engined started reving as it never has before. He said there is a chance that the car will need a new throttle body. I was also informed that there are some big problems with Toyota's electronic throttle bodies. I appreciate input. Car has been well maintained with oil changed every 5000 miles.
  • thanks for the input
    I found out this weekend they did not open the throttle body as they should have to inspect it. they did check the electronics of it and working fine.
    car is running fine, never did have idle issues etc.

    they did say it could have carbon build up in throttle body.

    is that possible?
  • The mechanic this morning open the throttle body and clean it. To me it did not look that dirty and he agreed. He feels that he has to test it a lot more to determine the exact problems now. The engine is now revving when it should be off at at stop. The concern is the electronic throttle body is not communicating to the hybrid synergy drive. Plus now I have read stories of cars accelerating suddenly to speeds of excess of 90mph.

    Thoughts ?

    Toyota is claiming the sudden accelerations are due to floor mats getting stuck under the accelerator. Lots of people who had this happen DID NOT have floor mats under the accelerator. It reminds me of Audi which had a similar problem, claiming "driver error".
    I got a preliminary recall notice telling me to remove my floor mats until further notice. I do not believe floor mats are the problem.
  • I have a 2009 camry hybrid and it will stop running while driving. I loose all power. All the gauges go dark then turn back on with no warning lights lite. It has happened 7 times in the past 3 months. I have to pull over and restart and everything will be fine. I have had it into the dealer 3 times. They tell me that they can not find anything wrong. There is no codes to be found. This is a very dangerous situation. Please help!!!! :sick:

    Go to a different dealer. You are right this is dangerous. It may be something as simple as a bad connection at the 12V battery, but it needs to be fixed. Your warranty is honoured at any Toyota dealer in North America, take advantage of that and don't patronize a dealer that isn't working for you.
  • They have checked all conections

    I suspect you are not going to get an answer of 'this is what is wrong...' in any of the forums. This is an intermittent problem and from my laymans perspective it sounds like you are losing power to the ECU. Could be a connector somewhere that isn't fully plugged in, a broken wire that breaks the connection when jostled, maybe a wire somewhere that has rubbed away the insulation and occasionally shorts out.

    Talk to a dealer and have them bring in an area rep to talk with you.

    And I doubt the dealer has check *all* the connections. They have check the ones that are easy to get to. To really check all, they would have to strip the car down to get at everything.
