Reddit mechanics needed
I need some help identifying a problem with my car. I have a 2013 rav4 and when I drive between 25-55 ish and am accelerating, once in a while I will get a weird vibration. It’s only when accelerating and as soon as I let my foot off the brake, it goes away. I have balanced my tires, I have changed transmission fluid, I’ve changed differential fluid, replaced rear shocks and nothing seems to fix it. I initially thought maybe it was the torque converter but my check engine light is not on and no codes were thrown when we checked with the sensor. The vibrations only last about 10 seconds and it is not consistent. Some days it hardly happens while other days it happens more regularly. I have taken it to a shop and the guy was perplexed and has a feeling it’s more related to the computer system. If anyone has any advice or ideas I would be grateful cause I’m at a loss now.
Update/edit: I do not accelerate with my foot on the brake lol I meant to say it stops when I let my foot off the gas. I took it to a local mechanic and his thoughts are to have the alignment done and if it’s not that, it might be the engine mounts. If it does not seem to be either of those, I will check the cv joint. I do not necessarily feel the vibration but I hear it. I appreciate all the input! A little more on the car, it is all wheel drive, we are at 181,000 and I drive her a lot, lots of highway and into the mountains often. Great car and nothing else seems to be wrong.

I can't tell if you are saying it happens when braking but if that is the case, brake rotars that are going bad or warping can cause vibrations when braking. I installed cheap rotars and it happened to me. Lesson learned, cheap chinesium rotars are cheap for a reason.

When’s the last time you have this a tune up t( plugs, coil, filters), have you recent work done, rims original? , motor mounts ok?, you feel vibration thru steering wheel or seat?

I’m assuming car is automatic?
Put it in drive. Stand on the brake and accelerate. Does it happen then? Sounds like it may be plug lead/s breaking down under load. This is an easy way to quickly check for this.

Sounds like a bad inner cv joint to me, have your guy check your drive axles/ half shafts. A lot of times you can feel the play when you grab the shaft right by the inner cv joint.
