Which Terrain years have the most problems?
Complaint volume by model year. Raw NHTSA totals, not adjusted for sales volume or time on the road, so older and higher-selling years accumulate more. Every year links to its full breakdown.
Sentiment is sharply divided and heavily dependent on model year and powertrain. Owners of newer models (2022+) report positive experiences with basic maintenance and no major issues up to 70,000 miles, describing the vehicle as comfortable and feature-rich. H
Severe engine problems: Includes rapid oil consumption (burning a full reservoir within 50 miles), cylinder misfires, piston damage, and complete engine failure requiring replacement, often under 100,000 miles. Linked to the 2.4L engine (2010-2017) and 1.5L turbo engine in later models. Frequency: very frequent.
Transmission issues: Includes stalling, failure to shift into 2nd or 3rd gear, violent jerking, and complete failure limiting speed to 20 mph (32 km/h). Reported across model years including 2016, 2020, and 2024. Frequency: very frequent.
Electrical system failures: Includes vehicles dying completely while stopped, losing all power, battery saver mode errors, and problematic auto-start/stop systems. Difficulty diagnosing root cause (alternator, starter, battery). Frequency: very frequent.
Check Engine Light / Emission System Faults: Recurrent codes including P0411 (secondary air injection), P0011 (camshaft timing), P305DF, and P305E. Often leads to expensive repairs like EGR cooler, exhaust manifold, and solenoid replacements. Frequency: recurrent.
Diesel-specific failures: For the diesel variant, reports of failed EGR coolers, catalytic converters burning through, and long parts wait times. Frequency: isolated but severe.
