10 Used-Car Brands With Serious Quality Concerns, According to American Experts

Shopping for a used vehicle is rarely easy. Buyers must balance budget, features, condition, and long-term reliability. Even choosing a respected automaker doesn't guarantee a trouble-free ownership experience, as certain models have developed reputations for costly repairs and recurring mechanical issues.

Based on assessments from American automotive experts and reliability studies, here are 10 brands whose older vehicles have drawn significant criticism for quality concerns.

Volvo: Reliability Concerns Hurt the Brand

While Volvo is known for safety, some reliability rankings place the Swedish automaker near the bottom of the industry. Among older vehicles, the Volvo S90 sedan has received particularly poor marks for dependability.

Cadillac: Premium Name, Mixed Results

Cadillac has struggled to shake reliability concerns across several model lines. Experts frequently point to the Cadillac ATS as one of the brand's more troublesome vehicles on the used market.

Tesla: Technology Doesn't Always Equal Reliability

Tesla's innovation has attracted loyal customers, but some automotive specialists argue that build quality and long-term dependability have not always matched expectations. The Model X crossover is often cited as one of the brand's most problematic vehicles.

Chrysler: Domestic Brand Faces Challenges

Chrysler continues to receive criticism in reliability rankings. The Chrysler Pacifica, despite its popularity as a family vehicle, has been singled out by some experts for recurring quality concerns.

Chevrolet: Improvement, But Problems Remain

Chevrolet has made gains in recent reliability evaluations, but certain models continue to generate complaints. The Chevrolet Traverse is frequently mentioned as one of the brand's weaker performers in long-term ownership studies.

Jeep: Stuck in the Middle

Jeep remains a favorite among SUV enthusiasts, yet reliability concerns persist. Much of the criticism has focused on the Jeep Compass, while several other models in the lineup have performed noticeably better.

Ford: Falling Short of Expectations

Ford lands in the middle tier of many reliability rankings. One model that continues to attract criticism is the Ford Mustang, which some experts say has experienced more issues than buyers might expect.

Mercedes-Benz: Luxury Doesn't Guarantee Dependability

The inclusion of Mercedes-Benz on this list may surprise some shoppers. However, reliability concerns surrounding certain E-Class models have weighed on the luxury automaker's overall standing in several surveys.

Nissan: An Unexpected Entry

Nissan's appearance among lower-ranked brands may come as a surprise. According to some experts, the Versa Note has been a major factor behind the brand's weaker reliability scores, despite enjoying strong sales in several markets.

Porsche: Just Missing the Top Tier

Porsche narrowly missed the group of highest-rated brands in some reliability evaluations. The Porsche Cayenne, in particular, has been cited as a model that negatively affected the company's overall performance.

It's worth noting that reliability ratings often vary depending on the model year, maintenance history, and vehicle condition. Even brands with lower overall scores can produce excellent vehicles, while highly rated automakers may have occasional problem models. For used-car shoppers, researching a specific model is often more important than relying solely on a brand's reputation.
