2019 Toyota Tundra Reliability Report

The engine stalls while driving, often with no warning light, and may not restart, so the truck needs a tow. Other reports describe slow starts and heavy shaking at startup. Dealers diagnose a failed fuel pump, but in most of these reports the VIN is not included in recall campaign 20V682000, and the truck goes unrepaired. Reprogramming the pump serves as a stopgap while the part is on backorder, and the stalling continues. Reported mileages run from about 36,348 to 117,000, with two near 100,000 or above.

The integrated trailer brake controller fails to detect the trailer or throws errors while towing, leaving the trailer without brakes. A rear brake also drags after a parking brake adjustment at the 5,000-mile service, causing violent shaking, a burning smell, and a hot rear wheel, and the problem returns after the first dealer fix. Rear brake pads soaked with oil from leaking shocks turn up at about 30,000 miles. A missing brake sensor is also mentioned.

The bed caves in under a load of wood at about 2,000 miles, the tailgate then fractures, and the body can be pushed in by hand. A sunroof shatters at highway speed with a gunshot-like bang and no debris present, leaving glass shards on the occupants. Smaller complaints cover a chrome hood bulge that keeps blowing off and a concern about crash test ratings.

Front turn signals are hard for other drivers to see. The incandescent 4157 bulbs get washed out by the LED daytime running lights and sit deep in the headlight housing, and the mirrors have no turn signals. The LED headlights pack with wet snow, which cuts visibility sharply. Low beams are described as lighting little beyond the hood, and a dealer finds them within spec after testing only in daylight.

Missing bolts let the wheel come off the column while driving, after a period of vibration and some looseness following dealer service. A leaking rack also needs replacement, with no recall notice received. Heavy rust on the control arms, sway bars, shocks, and struts gets flagged during a dealer inspection as a loss-of-control risk. In that case the dealer declines to help because the truck is out of warranty, and paid undercoating does not cover it.

Airbags fail to deploy when another vehicle hits the truck's rear side and spins it into a second impact with a guardrail or a truck trailer. All three complaints involve crashes, with 5 injuries in total. These crashes happen at about 45 and 75 mph. No warning lights show beforehand in one case, while every warning light flashes after the crash in another. The third report describes a crash caused by a driver's seizure and does not clearly point to an airbag fault.

Both complaints describe fuel pump symptoms: hard stalling, bucking while driving, hesitation, and little or no acceleration, along with flashing engine and pre-collision lights. A dealer assembles the fuel pump recall repair incorrectly in one report, and gas drips onto the driveway. After a second fix, the truck still feels like its pump is failing. False brake warnings with nothing ahead also show up here.
