Used Cars to Avoid at All Costs: The Models With the Worst Reliability Records

You've found it: the right color, the right features, a price that seems too good to be true. Sometimes it is. These are the used cars with the worst documented reliability records — not internet folklore, but survey scores, federal recalls, and class-action settlements. Skip them, or walk in knowing exactly what you're signing up for.

Bottom line up front
  • Owner-survey scores this low aren't quirks, they're warnings: 2016 Explorer 16/100, 2017 Sentra 9/100, 2020–21 Aviator 8/100, first-year F-150 PowerBoost 4/100 (Consumer Reports). Skip the model year, not just the model.
  • Nissan's CVT settlement covered ~520,000 vehicles with payouts up to $5,000 — but the claim window closed July 2025. Buy one now and the transmission risk is all yours.
  • A $150–$300 pre-purchase inspection is the cheapest insurance in this article — the price of one oil change on a Mercedes GLE that can carry "$70k repair bills" on a $30k used price.
  • Open recalls are live risk: 100,000+ more Hyundai Kona Electrics recalled in March 2026. Verify recall completion at nhtsa.gov before you sign, not after.

01Cross These Repeat Offenders Off Your List First

Fiat 500L (2014–2020). Quirky outside, miserable to own: transmission woes, electrical gremlins, low-rent materials, and a bottom-tier U.S. News rating (6.4/10 for 2020). Dodge Journey (2009–2020). Tempting third-row price, chronic brake and transmission complaints, and it left the market with almost no modern driver aids. Both are cheap used for the same reason old lottery tickets are cheap.

02Spot the Money Pits Hiding Behind Good Badges

Ford Explorer (2016–2019). One of America's best-selling SUVs, but these years carry historically dismal Consumer Reports survey scores (the 2016 scored 16/100 in CR's owner survey), with transmission, drive-system, and electronics complaints leading the file.

Nissan Sentra (2013–2017) — and friends with CVTs. The continuously variable transmissions of this era fail early and expensively; the 2017 Sentra scored 9/100 in CR's survey. The story now has a legal ending: Nissan's Murano/Maxima CVT class action settled in 2025, covering ~520,000 vehicles with payouts up to $5,000 — the claim window closed in July 2025 and checks went out in January 2026. If a seller mentions "the settlement will cover it," it won't. That ship sailed.

CarmaDeal Insight

The Nissan CVT settlement is the sharpest trap: ~520,000 vehicles, payouts to $5,000, claims closed July 2025, checks out January 2026. Every affected car still on the market carries the same failure risk with zero remaining compensation.

Scores from CR annual owner surveys in each model's worst year (2021–2022 cycles) — historical snapshots, not current ratings. The F-150 Hybrid has since recovered to average in CR's 2026 data.

03Don't Buy Someone Else's $70k Repair Bill

Lincoln Aviator (2020–2021) — infotainment, power equipment, and climate failures gave it one of CR's lowest-ever scores (8/100), and Lincoln still ranked below average in CR's 2025–26 survey. Mercedes-Benz GLE (2020–2022) — the 2022 was named CR's least reliable vehicle of its year, dragged down by electronics. When the tech in a $70k SUV stops working, it becomes a $30k used SUV with $70k repair bills.

CarmaDeal Insight

Depreciation on failed luxury tech cuts both ways: a $70k Mercedes GLE becoming a $30k used SUV looks like a bargain until the repair bills price like the original sticker. CarmaDeal's grading weights vehicle history at 15% and open recalls at 10% of Deal Score for exactly this reason.

04Read the Asterisk Before You Buy the Truck or EV

Ford F-150 Hybrid (2021). The first-year PowerBoost scored a shocking 4/100 — hybrid system, transmission, electronics. Worth knowing: CR's 2026 data shows the truck has since climbed back to average, so it's specifically the early builds to treat with caution. Jeep Gladiator (2020–2021) — Wrangler charm, Wrangler reliability (21/100).

Hyundai Kona Electric (2019–2021) and Chevrolet Bolt (2017–2022) both carry battery-fire recall histories. Two 2026 updates matter: Hyundai recalled another 100,000+ Kona EVs in March 2026 for battery-management software, and on the Bolt, only 2017–2019 packs were replaced outright — most 2020–2022 cars got diagnostic software instead of new batteries. A used Bolt can be a genuine bargain if the recall work is documented. That's a paperwork question, not a vibes question.

New for 2026: CR's latest least-reliable list adds the Chrysler Pacifica Hybrid, Mazda CX-90 (turbo engine failures), Kia EV6, Genesis GV60, and Chevy Blazer EV. First-year everything remains the most expensive thing you can buy used.
