My check engine light came on when I was traveling in Oregon. I didn't notice any major changes in my vehicle's performance. Drove it all the way back to Colorado without issues. It went off and came back on several times. I replaced the cabin air filter, engine air filter and put fuel injector cleaner in the vehicle. Finally I took it in to the Toyota dealership to get an oil change and then the check engine light came back on. I paid for them to do a diagnostic test and they stated they were almost certain it was the 2nd fuel injector running rich. Brought it back a week later for the repair. Fyi...I was still getting 20 mpg in fuel and I wasn't noticing anything major in performance. They replaced the fuel injector and then the check engine light came back on with a different code. They are now running "another" more expensive diagnostic test and I still don't have my truck. They are saying it could be the 2nd cylinder or the engine and claiming it has 150,000 miles so I should expect these issues (and conveniently my warranty has run out).

Fuel pump failure at 63k miles. Check Engine light came on. P0171 code thrown. Truck began hard starting, and rough idling. Stalled on freeway, stuck at 4k RPM and would not drop. Had to pull off and restart. Checked entire system with certified independent service/AAA mechanic and fuel pump was diagnosed. Fuel pump whines in tank, and fuel trim levels are way off... maxing out in output (39), and falling into the negatives in short term trim levels. All other components testing ok/within ranges. Massive recall on fuel pump for my exact same year/make/model/engine, but my VIN does not show as affected... clearly it has the same issue. I need this pump fixed ASAP, as does everyone else affected that did not get to be apart of the recall.

I purchased and drove a brand new 2019 toyota tacoma trd off road 4x4 6'bed off the lot, with only ten miles on it. I was driving on the interstate back to my hometown and was broken down on the side of the road at 236 miles. While driving on the interstate, the RPM odometer gauge suddenly began to jump rapidly while the vehicle simultaneously lost power and speed and the whole vehicle lurched forward abruptly a few times. I pulled over immediately. I turned off the vehicle. Turned it back on, and it lurched forward and was clearly not drivable so I turned it back off. At no point did any check engine light or warning signals go off on the vehicle either while driving or after having pulled over. It was three hours before roadside assistance got a tow truck to arrive. Upon loading the vehicle onto the tow truck, it was clear that transmission fluid was leaking in large quantities as it was visibly pooled where it had been parked, had leaked all over the underside of the vehicle and continued to pour out all over the tow truck bed. The service department at the nearest toyota dealership where the tow truck had delivered the vehicle to later inspected the vehicle and informed me that a manufacturer seal had failed causing the transmission to leak and that the entire transmission needed to be replaced. This vehicle should have never passed quality assurance/quality control and should never have left the manufacturer. This vehicle's final assembly point was listed as baja california, mexico.
