The top components are engine (158, of which 5 a fire and 1 an injury), power train (100, of which 3 mention a crash and 2 a fire) and service brakes (35, of which 4 mention a crash and 3 an injury). Across all 398 reports, 13 describe a crash, 9 a fire and 8 at least one injury.

Changes from 2017
EPA lists a 2.4-litre four-cylinder for 2018 that does not appear in the 2017 listing; the hydrogen fuel cell is listed for 2017 but not for 2018; two recall campaigns name one of the two years and not the other (electrical system and engine).

Fuel economy and running cost
Its most efficient version (1.6-litre 4-cylinder) is rated 27 mpg combined, close to the median for the 2018 SUVs we cover (median 25 mpg across 51 other EPA listings); the thirstiest version is rated 22 mpg. At 15,000 miles a year and the national average regular gasoline price of $4.28 (EIA, week of Oct 19, 2026), fuel would cost about $2,380 a year in the most efficient version and about $2,920 in the thirstiest.

An engine compartment fire can increase the risk of injury or crash.
Hyundai Motor America (Hyundai) recalled certain 2019-2021 Tucson vehicles on September 4, 2020. On December 30, 2020, Hyundai expanded the recall population, and added certain 2016-2018 Tucson vehicles. The Anti-lock Brake Hydraulic Electronic Control Unit (HECU) could corrode internally and cause an electrical short, possibly resulting in an engine compartment fire.
Consequence: An engine compartment fire can increase the risk of injury or crash.
Remedy: Hyundai will notify owners, and dealers will replace the HECU fuse. For 2019-2021 model years, the Electronic Stability Control (ESC) software will also be updated. Recall repairs will be performed free of charge. Owners are advised to park outside and away from structures as a precaution until the recall repair is complete. The recall began November 2, 2020.
