Owner reports

Selected complaints filed with NHTSA by 2019 Toyota Tacoma owners, lightly cleaned up (personal details are redacted by NHTSA).

Fuel system - vehicle surged (high RPMS) while gearshift lever was in the Drive position after release of pressure on the accelerator as I was parking the vehicle surged and smashed into a cement post, the vehicle traveled approximately 10 to 15 feet. The vehicle is currently at the dealership where an independent contractor, who is contracted by Toyota, will be doing a visual and diagnostic analysis. I expect the vehicle to be returned to me on 1/19/2023. The vehicle and components have not been inspected by any other individual at this time. There were no warning lights on prior to the surge. Unknown if any warning light came during the incident which I believe was two (2) seconds until impact with the post.

To whom it may concern, I was issued a recall on this vehicle for a defective fuel pump. I have been attempting to rectify the situation through City World Toyota located at 3333 Boston Road, Bronx, NY 10469. On 7/1/2021 I spoke with Jorcelyn and was told the part needed to replace the defective component was not in stock and it would be ordered and available within a 4 weeks. I was told I would receive a call back and never did. On 8/9/2021, over a month later, I got in touch with Wasile and was again told the part was not in stock. I was told they would check and then call back the following day. Again, I never received a call back. On 8/12/2021 I called again and was told they do not have the part in stock and would call back with an ETA. It was been months since this recall was issued and City World Toyota has not rectified the issue. …

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. …

In October of 2020 they replaced the fuel pump then noticed a hose was bad it would take 2 months to get that hose.. Upon driving my vehicle I noticed an 4mpg lost. was getting 22 mpg prior to the change. I have been in contact w/toyota in Texas and they send a 'factory rep' to look at my truck. here is the problem he snapped a picture stating my truck got 28.6 mpg, upon getting into my truck it read 20.6 mpg. they refuse to replace the fuel pump and hose at another dealership. The secretary at toyota said if they would change and it didn't make a difference they would be wasteful. I said replace it and we will see however you say you not going with the customer the paid good hard earns money for this vehicle we will never know. all I want: is the have a new fuel pump and hose put into my Tacoma, it may not or it will prove there was a problem. …

The contact owns a 2019 Toyota Tacoma. The contact stated that after starting the vehicle, the vehicle was idling abnormally rough. After shifting into driving and releasing the brake pedal with his foot off the accelerator pedal, the vehicle briefly independently accelerated. Upon reaching an undisclosed speed, the vehicle returned to normal functionality, but the failure became a regular occurrence. The contact stated that the failure first occurred after the dealer had replaced the high-pressure fuel pump. No warning lights were illuminated. The vehicle was taken to the dealer, who was unable to duplicate the failure. The vehicle was not repaired. The manufacturer was notified of the failure, and a case was opened. The failure mileage was unknown.

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.

Full tank of fuel and dashboard is showing 30 miles until empty warning. I have received the engine warning sign on my dashboard as well when this happens. This issue also affects me on the road when I am pressing the accelerator and the engine will not respond, this gas been an issue since they did the fuel pup recall. With a delay in acceleration comes a delay on the brake system as well, two intenses that I've had to press my foot as hard as possible on the brake to avoid a collusion with another vehicle. The last time this happened was on 4/17/2022

This 2019 truck feels like it just doesn't want to go. It struggles to go up ANY hill no matter how small. The engine jumps feels like it's got a heart beat while riding. The gas mileage is horrendous and awful the 2015 was all around a better truck I read somewhere that Toyota recalled a bunch of 2019 trucks for a gas line rip was causing fires and whatever else. I thought for sure it had to be my trucks issue bc that would absolutely explain why it's running so weird and ragged. The poor thing ... I'm very worried about it.

the differential skid plate was manufactured in a way that one of the brackets make contact with the fuel tank of the truck. It rubs and compromises the integrity of the tank. Possibly leading to a puncture and leak. I brought it to the attention of the manufacturer, and they have stated that they received several complaints from customers and redesigned the skid plate to prevent this. However they refused to replace mine and others, they also have taken NO steps to notify owners of this safety hazard.

While driving at Highway speeds fuel pump failed resulting in near miss collision on Interstate. Initial fuel pump was replaced with recall. This is second pump that failed. Vehicle towed to Bob Tyler Toyota in Pensacola Fl where fuel pump replaced by owner. Toyota refuses to pay for pump even though class action lawsuit resulted in Toyota being responsible for reimbursement. Vehicle has only 36000 miles.
