Gary J2 Posted January 31, 2017 Share Posted January 31, 2017 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).

TrevC Posted January 31, 2017 Share Posted January 31, 2017 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 Cheers Trevor Quote Link to comment Share on other sites More sharing options...
Gary J2 Posted February 20, 2017 Author Share Posted February 20, 2017 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. Quote Link to comment Share on other sites More sharing options...
