On two occasions recently, my 2016 RX has experienced an acceleration problem.


--  The first time, it occurred when I was backing out of a parking space at a Freeway Rest Stop. I started the car, put it in Reverse and let my foot off the brake, to "creep" out. Nothing happened. I pressed the accelerator a bit and still nothing. I pressed harder and nada. I put it in Drive and it inched forward a bit. I again put it in Reverse and removed my foot from the brake and everything worked normally. No warning lights appeared on the instrument panel.

--  A few weeks later, I started the car normally, put it in Drive and pulled from the curb parking space into the traffic lane. The damned thing wouldn't accelerate and I almost got rear-ended. The speed topped out at 8mph, according to my HUD. A yellow warning triangle, over the 80mph marker on the speedometer lit for about a half-second. The Dealer couldn't duplicate the problem on a test drive (one round trip from the shop of about a mile) nor were there any codes stored in the diagnostics unit.

Has anyone else experienced an acceleration problem? (NOTE: The car is always in the Normal driving mode. I never use "Sport" or "Econ" Modes).

Thanks

Hi Gary

It does sound like the transmission is not engaging correctly and applying full hydraulic pressure....could be a sensor issue.

I would definitely take it back to the dealers to run more tests as this is quite a dangerous occurrence by the sound of it

Keep us update on how this progresses

This doesn't appear to be a problem with the transmission. There was no acceleration OR increase in engine RPM. The RPM reached about 1000.

Vehicle is still under warranty, have dealership calibrate/update the ecm on your vehicle

      Hello everyone, my car makes noise again. When it is cold in the morning, the car is idle with around 1400 rpm at first and the noise sounds like coming out from the back of the engine. When I drive it, the sound is noticeable at 1400 - 2200 rpm when I accelerate from stop or from low speed. It goes with engine rpm, not the car speed. What is the possible cause? Actually, the noise is also noticeable during the day but definitely much better than in the morning when it is cold. I am thinking about EGR pipe, MAF, or EGR temperature sensor but want to check if it makes sense.

      I have 2007 ES 350 with 145,000 miles. Last year started having transmission flares intermittently, couldn't duplicate at dealer. It went away completely for past 6-8 months and now started up again. My question is, is this symptom of a possible catestrophic failure or something I can live with so long as it is not happening often. Due to age of car I don't think I will keep more than another year and sure don't want to put money in it. I saw multiple posts about this problem but couldn't determine the severity of the problem or is it just a nuisance?
