#5261 of 5646 camry 2001 frequent jump start and battery issue
Jan 07, 2011 (5:31 pm)
I have a toyota camry 2001. For past two months i need to do frequent jump start because battery dies off in the morning. Took it to sears first time , checked the charging system everything seems to be good. Replaced the new battery . After 5 days again needs to jump start. Took it to toyota dealership, left there for 2 days, they could not find any shorting or draw problem. According to them electrical system is good. They want to rip the dashboard for $ 500 and see the problem. I said no . Battery withstands for 2-4 days without charging if i drive 40 minutes in the morning and evening. If i dont drive during weekends it dies. twice in week i am jump starting the car now. What could be the issue.
Thanks for your help.

your problem sounds like the one that is described in the TSB and if you are still in warranty, covered by toyota.
it should also be an easy self help problem if your bar is not twisted (like mine was) and is just loose, you would just need to tie the bar up so it doesnt drop down and touch the speakers.
notmybmw is correct as to the location of the trunk torsion bar.

in addition, another sign that you have a trunk torsion bar problem -- my trunk wasn't opening up all the way and would drop down half way (so that when i was bending over to load the trunk, my head would bump into the trunk b/c i was expecting it to be it is normal higher position.
#5264 of 5646 2007 Camry SE V6 Front Passenger Side Thumping/Rattle Sound Over Bumps
Jan 17, 2011 (8:35 am)
Hello Everyone. I hope someone here can help me figure this problem out. I have just purchased my 07 SE V6 with 17k miles on the 23rd of December. The car was certified and i also purchased the platinum warranty so that i can have a full warranty on the car. It wasn't until about two weeks ago i started noticing the thumping/rattle sound coming from the front passenger side strut area. I took it to the dealership last week and they replaced both front struts and mounts. I got the car back from them this past Friday (1/14/11) and am still experiencing the same problem but this time it sounds even worse. I took it back this morning and had the tech who certified the car and also replaced the struts look at it and with no surprise they claim that they didn't hear anything or find anything wrong. The noise is a lot more noticeable now then it ever was before. So in the process of trying to make something better it ended up becoming worse. Based on all the threads I've read a lot of people say that it maybe the swaybar bushings and or endlinks. Could it be that or could i just happen to have gotten another defective strut? Any ideas or suggestions would be greatly appreciated.

Take it back again and tell the tech this time WE WILL GO FOR A RIDE together. But before going scout out the neighborhood and find the worst bumpy road you can so there will be no question.

Thanks for responding to my question. As you recommended, I have listened carefully as I step on the brake with the ignition on, and I fail to hear any "click" coming from the area near the shifter.
I hadn't experienced the problem for about a month, and then today it occurred again. I turned off the ignition. Restarted the car. Then I mashed down on the brake. At that point I was able to get the car to shift out of brake and into drive. Maybe it was just dumb luck, but it seemed to work.

Can anyone tell why I am getting very poor gas milage in my 2007 V-6 SE camry.
I have no codes coming up tire pressure is 32 My car has had many shifting issues which the dealership says is normal though I questioned that.
My last tank I got 15mpg local driving. I do let the car warm up for 5 mins in the morning on these cold winter days in chicago. I've never seen this kind of drop before from summer to winter.

I'm having the same problem as you with poor gas milage in my 2007 XLE V-6 Camry. I've had shifting problems with some minor tach spiking as well. I'm averaging 14.5 miles per gallon around town and I live in South Florida.

There are four known possibilities for the poor winter mileage you are experiencing: One is related to the length of the trips you are making; the shorter the trips you make, the lower your mileage will be. This is caused by the fact that the engine's fuel consumption is always higher during the time before it reaches full operating temperature (because a cold engine has less combustion efficiency; combined with the richer fuel mixtures used during the warm up cycle). It is compounded by the increased friction created by the cold and thus relatively thick engine and transmission oil. In cold weather, it often requires 5 miles of driving before the coolant and oil temperatures both reach normal levels. Only after driving 5 miles will the gas mileage become anywhere near normal. And many people use their car for shorter trips in the winter than they do in the summer.
The second factor is that most engines experience lower than normal gas mileage whenever the ambient air temperature is below 55 degrees F. This is due to the increased amount of engine heat lost to the atmosphere through the cooling system in cold weather. The colder the weather; the worse your gas mileage will be.
The third factor is the greater percentages of volatile compounds and oxygenating additives (typically ethanol) used in fuel during wintertime. This is done to reduce carbon monoxide emissions and improve starting. But these compounds create worse fuel economy. If you can find gas which has less ethanol in it; your fuel economy will increase. The colder the weather is; the greater the mileage loss will be with ethanol in the fuel.
The fourth factor is that Camry V-6 motors tend to carbon up spark plugs in cold starting and idling. The stock plug design was chosen for use in normal driving. We have found that using a plug with the stock heat range; but with deeper projection of the electrodes and insulator into the combustion chamber will significantly improve cold engine running and fuel economy. NGK and E3 both make plugs of this type. But, if the replacement plug type is chosen by an ignorant or inexperienced person; this type of change can potentially cause engine damage.
Over the years; Toyota has occasionally revised the computer calibrations on their motors, when experience with a given model was found to result in poor performance. When a revised engine control calibration is released by the factory for a given model; an instructional advisory called a TSB (technical service bulletin) is sent to the dealerships. The dealerships can apply this upgraded calibration to applicable models. However; not all dealerships are motivated to keep accurate records of the TSBs they have received; nor to freely apply them to vehicles without some persuasion by owners. It might take some research to accurately determine whether there is a TSB available for your model; but there were several upgrades for shifting and engine response issued during the late 2000s.

Hey, Chuck.....hope things are running better with your Camry!
Zaken1 gave a good, comprehensive explanation of possible causes for your diminished gas mileage.....but there is one more critical factor for you to consider while "warming up your car for 5 minutes in the morning"!
During this period of time, your fuel consumption (while cold) is INCREASED for all the reasons zaken1 outlined. On TOP of that......you're going nowhere while warming up.....therefore getting ZERO miles to the gallon.
Modern engines require next to NO WARMUP, so, when you get into your car on a chilly morning....start it up....and go. Wait just long enough for all the warning lights to go off (about 5 to 10 SECONDS...not minutes), then put it in gear and GENTLY proceed down the road. Don't hammer the accelerator while your car is in 'warm-up mode', but don't be afraid to get moving on your journey. This will help things warm up even quicker than if you were standing still......AND get some "mileage" out of that higher-than-normal fuel/air mixture the car is running on!
Cheers, from the chilly white north!
