The 4runner hesitates at 40mph and 60mph when trying to coast/maintain speed with slight pressure on the gas pedal. At other speeds or while accelerating at 40/60mph there is no hesitation. I took it to the dealership, but they said they can't replicate the problem. It is still happening though.

I have a 2015 4runner (VIN: [xxx]) I purchased brand new. It currently has less than 50K miles on it. A few weeks ago it started periodically going into "limp? mode while driving at highway speeds. My two toddlers were in the vehicle the first time this happened; I almost lost control since the ?tractional control" disabled concurrently. I took the vehicle to multiple mechanics who confirmed the diagnostic code P2445 (secondary air injection pump). I was shocked to hear this because the vehicle is relatively new and exceptionally well maintained. I looked online and the failure of this component appears to be a systemic issue with Toyota 4runners and Tacoma. The fact that this component failed after a short duration in such a sudden and violent way is very dangerous. I submitted a formal complaint to Toyota and they denied knowledge of this issues despite hundreds of folks reporting identical problems on their 4runners & Tacoma. For a nominal fee per vehicle Toyota could fix this issue, which also has environmental implications, but instead they are being disingenuous and denying this major systemic safety hazard.

The contact owns a 2015 Toyota 4runner. While driving in the left lane at approximately 70 mph, the vehicle lost power. The contact stated that the vehicle seized and was unable to be moved. The engine was still running, but the vehicle would not accelerate. All the indicators on the instrument panel illuminated at the time of the failure. Modern Toyota (3178 peters creek pkwy, winston-salem, nc 27127) diagnosed the vehicle, but the cause of the failure was undetermined. The vehicle was not repaired. The manufacturer was not notified of the failure. The VIN was unknown. The approximate failure mileage was 28,000.

I had 20,000 miles and bought the veichle brand new and went to leave work and my veichle was struggling to stay going and my check engine light was flashining. When I'd go to reverse the vehicle would struggle and act like it was going to die. I had to go 20mph on the side roads about 15 miles to the dealer. The RPM shouldn't shift. It was caused by a mouse I guess? since they use soy base and see this a lot. So fustrating when you pay $38,000 for a veichle. I'd much rather drive my older 2010 Honda that never had an issue with so called a mouse. They of course wouldn't cover it. To top it off I had a major oil leak at 19,000 miles causing about $6,000 worth of damage. Which was the factory's fault they said. It was covered by warrenty, but still it's ridiculous. I bought the car new. With 1 mile on it, fresh off the truck. As of right now I have no faith in Toyota. I'm afraid my veichle will break down on me. Which I shouldn't have to feel when I buy a new car. So disappointed in Toyota. Something needs to be done.
