Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
The 2019 model year records 6 recalls and 242 TSBs, figures that exceed those of every prior year in the dataset back to 2002—including the 2016 model’s 1 recall and 62 TSBs—and that tie 2020 for the generation’s highest recall count while carrying the highest TSB total of any year shown. Across the 2019–2023 arc, the federal record shows a downward trend in factory interventions, with recalls falling from 6 to 2 and TSBs dropping from 242 to 36, even as owner complaints remain negligible throughout the generation at 5, 4, 0, 1, and 0 respectively. The 2019 model’s five complaints are reported as two for the engine, one for the electrical system, one for steering, and one in a combined air-bags/structure/forward-collision-avoidance category, with one crash complaint and zero fire complaints, though the data does not specify root causes. Given that later years carry comparable recall exposure with significantly fewer TSBs, a 2019 unit is reasonable to purchase if all recall campaigns are complete, though 2021–2023 examples present a lower volume of factory service bulletins.
