2023 Toyota Tundra Reliability Report

Two reports describe fires starting in the engine bay. One began with an acrid smell after the heaters were switched on. The other came shortly after a 45,000-mile service, with shaking and loss of power before the fire. A common nuisance is a fuel gauge that jumps to full when the tank is not full, so the driver could run dry. Other complaints include a blacked-out instrument cluster, parking and lane cameras glitching in rain, stalling with engine knock, a sudden loss of oil pressure, and a musty HVAC smell when it rains.

The fuel gauge reads full when the tank is not, often after parking nose-up on an incline. One owner needed 14.4 gallons to fill a tank the gauge showed as more than 3/4 full. Dealers rarely find a fix, and online workarounds fail for many owners. Throttle lag from a stop, followed by a lurch, persists even after a software flash or service bulletin. Owners also complain that the fire-risk recall 23TA09 went months without an available remedy. A hybrid owner reports fuel leaking onto a garage floor.

Acceleration from a stop often stalls for 2 to 3 seconds and then surges, leaving drivers exposed in cross traffic. Some first notice it around 10K miles, and it shows up more often shortly after startup. Dealers often cannot reproduce it, and an ECU flash did little for one owner. One driver was hit while pulling out. Others lose power while merging onto highways. The pre-collision system brakes hard with no reason, once from 65 to about 35 mph, and lane keep assist fights the wheel.

Brakes squeal or screech from new, worse after startup and in rain. Pad and rotor work often fails to stop it, and some dealers call it a known issue or are still waiting on parts. Several owners report the automatic emergency system slamming the truck to a stop with nothing ahead, including once from 40 mph. In one fire, the brakes failed completely while the truck was moving. Other reports are open recalls with no parts and heavy oil consumption with misfires during a dealer test.

Nearly every report concerns recall 23V566000. Owners are notified, but dealers have no parts for the repair, and one dealer sold reserved parts before the appointment. The underlying risk is real. One owner reports a fire at the driver-side fuel tank that destroyed the truck, and another smelled fuel while driving at 30,000 miles. Other complaints include a fuel gauge that reads high, low fuel economy, and screens that shut off or demand a PIN while driving.

The truck pulls hard to the right, and repeated alignments fail to fix it or make it worse. That pull goes with fast front tire wear. Some TRD Pro owners say the factory alignment specs were wrong. Several reports describe engine stalls at speed that leave steering heavy, including one at 57,000 miles where the VIN was not in the recall. Owners also report clicking from the front suspension when turning, vibration at low speeds, and multiple safety-system warnings appearing at once.

Factory 265/60R20 tires wear hard on the outer edges, with dealers recommending new tires at 16,920 miles and calling one tire unsafe at 19,500. Owners tie the wear to alignment, and one got only two tires replaced. A rear tire split its sidewall at 55 mph with 4,601 miles on the truck. One crash report describes the Bridgestone Dueler H/T tires swaying on the highway, worse in rain and with a trailer fishtailing.
