Question about 2008 Toyota Highlander

Open Question

Engine and/or transmission "flutters" around 35-45 mph.

During normal driving, my 08 Highlander AWD Sport noticably flutters starting around 35mph and up to 45-50mph if gently accelerating or holding speed in this range. Occurs regularly. Have noticed that heavier pressure on accelerator (accelerating faster up through and beyond this speed range) resolves/eliminates this event in this speed range. Still concerns me. Will be taking vehicle to dealer service dept. Only 1 week since purchase. Wanted to spread the word to see if there are others who have had dealer able to fix the issue. Would like to know what was done.
Thanks

    I have the same problem but have yet to contact the dealer. However, I did read in the qwners manual that this is normal and does not indicate a malfunction. I wish I knew that.

    Just bought an 08 Highlander Base 4x4, same problem is evident. Thought the truck was driving over warped roadway at first but it happened on smooth roads as well.

SOURCE: flutter type noise when truck gets warmed up

If you have not adjusted the valves that would be a good place to start, 117,000 is not high miles for your engine, but valve lash should be done every 60,000 at least.

SOURCE: Rattling noise when the car idles in drive/reverse position or...

predetonation,called ping can result from poor quality fuel,and high outside air temperature,it happens at lower speeds under load. a rattle could also be from the heat shield around the catalytic converter,it would buzz more if you wer idling and turned up the fan,the fan pulls quite a bit of current,and tha a/c will load the engine a bit.

Vibration in transmission


I do not know if this vehicle has a torque converter lockup or not, but sounds like it. Does the transmission stop shaking when you go over 65? Some vehicles have a torque converter lockup, which means when the vehicle is traveling at a certain speed in high gear the torque converter "locks" and there is no slippage to the transmission resulting in better fuel economy. if the torque converter doesn't "unlock" when you slow down to say 45 then the engine will "lug" causing vibration. If this is the case you are not hurting anything by driving, just shift to 3 when it shakes then upshift under lighter load, or take it to a shop that replaces transmission sensors.

2002 chevy s10 temperature gauge jumping around, feels like automatic transmission slipping at speeds above 60 mph


Do you have an OBDII scanner to check the real temperature? Want to make sure it's not overheating. If it's normal, could be your temperature sensor starting to go out, or ignition switch. Any check engine lights? If so, get the code for me, can go from there. At a constant speed, you sure it wasn't a misfire instead? Check your trans fluid, make sure it's full. I was just in Tahoe, pretty sad not much snow at all.

Engine check warning light


Take the vehicle to your local auto parts store and have them read the check engine light code for you and then you can bring that back here and someone will be able to help you figure out what is going on. Just because you can't tell what it is right now doesn't mean that something isn't going bad very soon. Let us know. Thanks for using FixYa!

2008 Toyota Highlander Sport AWD when starting off the engine seems to rev fairly high for very small vehicle movement. At idle engine revs around 1000RPM. Gas mileage is poor,17MPG for about 80% city, 20%...


yes it is normal many customers complain about how the newer cars are not as responsive from a stop basically you have to hit the gas then the car goes seems to rev high to people with not a lot of movement becausse of this its because the newer cars are throttle by wire when you hit the gas it sends a electrical signal to the throttle to go instead of a few yyears back they were you hit the gas and the cable attached to gas pedal pulls back throtttle much more responsive hope this helps
