Toyota Highlander Hybrid
Problems & Worst Years
Every reported problem for the Toyota Highlander Hybrid, model year by model year — ranked from 250 federal NHTSA complaints across 2010–2017.
Only one model year appears for the Highlander Hybrid, 2017, and its complaints center heavily on the battery and the electrical systems it feeds. Battery issues leading to engine stalling and broader electrical malfunctions top the list at 30 reports, nearly a quarter of the year's 122 total complaints. Engine misfire and stalling follow at 19 reports, and two related powertrain entries — general power train issues (17) and outright power train malfunction (12) — round out a picture where stalling, in one form or another, touches battery, engine, and drivetrain complaints alike.
A smaller cluster of 10 owners reported sunroof failure, unrelated to the stalling theme. Two of the year's fourteen distinct problems are rated safety-severity, and no NHTSA recall campaigns appear in this dataset for the model year, meaning these are owner-filed reports rather than formally recalled defects. The concentration of complaints around battery-driven stalling, rather than a single catastrophic failure mode, suggests an electrical system that misbehaves intermittently more than one that fails outright — which can make the problem harder to catch on a short test drive.
Anyone shopping a 2017 Highlander Hybrid should pay particular attention to how the battery and electrical system behave — watch for stalling at idle or during acceleration, and ask whether the battery has ever been serviced or replaced. Because only one model year appears here, there's no multi-year trend to lean on, and it's worth remembering that these numbers describe what owners reported to NHTSA rather than a measured failure rate; a careful pre-purchase inspection and full service history will tell you more than the year on the title.
