general problems of the 2015 Toyota Tacoma

Driving around a winding turn incline , Tacoma hesitated at 40 mph while going down incline. Tacoma rpms fluctuates at 40 mph as if the engine is having difficulty accelerating. You can hear the engine stalling or shuttering to catch up to speed. This is occurred driving at a steady 40mph. The Tacoma seems to be stalling out at a certain speed limit and rpm at 40 mph. It only has this symptom at 40 mph going down an incline. This is dangerous and there were vehicles behind me traveling at the same speed going around a winding turn incline. This could of caused a pile up because of the Tacoma struggling to maintain speed and accelerate to keep speed. Ive taken this Tacoma to nalley dealer and they've replicated the problem but thought if resetting driving mode would clear the problem. That did not clear the problem and its currently causing the same issue. The tech seems clueless in whats going on when ive explained that it happens at a certain mph and while going down incline. The tech know that this has occurred when he taken the Tacoma on a test run. Some how the tech think a reset of driver style handling is the issue. The Tacoma isn' responding to a driver style handling reset. Ive scheduled another appointment with the dealer to have the tech check the Tacoma again. There are other years of Tacoma's that have this problem. I believe this particular Tacoma has the same issue as the other Tacoma years that are under a torque converter recall. The symptoms are identical compared to other Tacoma year models under the torque converter recalls. I don' want this problem to become a hazard where the Tacoma cause a massive pile up in traffic because of the unstable mph at 40 mph. The 2015 Tacoma doesn't keep steady speed limit at 40 mph going down incline. The rpm fluctuates at 40 mph as if its trying to distinguish what speed limit the engine is driving at. The Tacoma is stalling at 40 mph while making a shutter sound while driving down inclines and winding turns.

Due to the failure of the secondary air pump system vehicle will experience a sudden loss of power and could cause a loss of control. Toyota is aware of the problem but will not issue a recall.

U joint broke while driving.

Secondary air injection system (sais) - one way flapper below injector valve sticks either open/closed, throws off whole sais and sets car in limp mode with corresponding check engine light code.

On three different occasions I was stationary with the gear shift in drive and my foot firmly on the break,when the rpm's suddenly revel up to over 5000 rpm and the truck trying to lurch forward. I had to ram the gear shift into neutral to get the rpm's to drop down. The last time it happened at the bank parking lot. I came to a complete stop to let a woman cross in front of me to her car. All of the sudden the engine revs way up with me trying to hold the truck back as it was lurching forward. She thought I was trying to run over her. I don't know who was more scared, her or me. I jammed it into neutral and after a few more seconds the revs dropped down to idle again. I'm taking it to modesto Toyota tomorrow to get it looked at on August the 6th. The truck only has 63000 miles on it. The other two times it happened were in my driveway and at my storage unit. Both times I was stationary as well, truck in drive, foot on break. Very dangerous!.

I purchased the vehicle new & had the dealer install the optional Toyota trd supercharger at approximately 5k miles. At approximately 10k+ miles, I started to notice while at cruising speed (30-50mph) if I needed rapid acceleration to pass or enter the highway, the tachometer would show the engine revving but the vehicle will not accelerate. The vehicle is used for commuting 100 mi daily (highway)the Toyota dealer confirmed the problem / removed the transmission to access the clutch & found no abnormal wear or defect. Toyota now states because I modified the vehicle with the Toyota optional trd dealer installed supercharger, there is no warranty & I have to pay for the repair. . Read more...
