2007 toyota rav4 cold start is slow. V6 2WD 40 K miles always started quickly when cold, but now requires that I depress the pedal a little, and still takes longer than normal to start. (Cold in Houston is below 50 deg...)

Hi, you could check your engine mounts.

This may help: http://www.toyotanation.com/forum/274-2nd-generation-2004-2010/199861-04-sienna-transmission-lock.html
There are multiple issues here.Won't crank? Go direct to starter.

You may have a bad brake liggt switch or just need to adjust it. It is found on the back side of the brake pedal. When the brake is depressed the button should come out when released the button should be depressed telling the lights to come on or go off

Hi Beth usually when shifter is stuck there is a locking mechanism and keeps shifter from engaging unless brake is depressed to release the lock. If you hear a clicking sound when pedal is depressed then switch is probably ok and its probably the steering wheel lock. First try with your spare key to start the vehicle(old key may be worn ). If that doesn't do it then try with WD 40 a very little in ignition key hole or on the key work it slowly and see what happens. If none of these suggestions work its probably the steering wheel lock and that requires surgery. Keep me post best of luck

only slow starts,??? runs prefect, the CEL is not stuck on driving?
CHeck engine light out , driving?????
are you doing the full 60,000 mile tune up list or just spark plugs.....
bad fuel, car sits for months on end?
running summer fuel in winter?
who cold is it, 70F in key west or -50F in Alaska. we have not a clue.

Your 2007 RAV4 requires 4.5 quarts SAE 5w20 with filter change. I use Pennzoil and highly recommend it but all major brands are good. Use a quality filter such as Wix, Purolator, or Bosch. Change your oil/filter every 5,000 miles if using conventional oil and every 7,000 miles if using synthetic if you drive normally.

I would say 4 seconds would be max on a bad day.
If it were my car I would try some WD 40 sprayed on to and around the linkage of the carburetor and work that linkage a little. It sounds like the choke is not completely closing when it needs to be or is not opening all the way up after it warms. Just a thought. Also you may want to check the air filter to see if it needs replaced. Good Luck, The Raz

That sounds like a left front wheel bearing gone bad My friend.. turning right transfers weight to the left side and it probably has a roar similar to a turbo fan jet.. Try it and lemmie know.. thank you

Make sure you have a fully charged battery. When starting the car, push the gas pedal down to the floor to engage the choke. Then push pedal halfway down and turn the ignition. Try jump starting to see if it is the battery. If it still turns slow it may be a bad starter.

I just did this procedure 5 mins ago on my 2007 RAV....some procedures state to do it from the ODO position but that will not work....use the procedure below.

Set odometer to Trip A
Turn the key off
press and hold the ODO button.
Turn key to ON
Continue holding button while the light goes through the series of the ----countdown and then flashes 0000. Release the button and turn key to OFF.

Thats it!
