Buying American-made vehicles is a point of pride for many drivers, but not all U.S.-built models are created equal, especially when it comes to long-term costs. Some domestic cars are notorious among mechanics for their high repair frequency, expensive parts, or hard-to-service components. Even if the sticker price looks good at the dealership, the real damage often shows up in your repair bills. If you’re planning to buy used or already own one of these vehicles, it’s worth knowing which models mechanics say are expensive American cars to maintain. These four are regularly flagged as budget busters in repair shops across the country.
1. Chrysler 300
The Chrysler 300 may be a bold and stylish sedan, but it’s also one of the most expensive American cars to maintain over time. Mechanics report frequent issues with the electrical system, suspension components, and engine sensors. Parts aren’t cheap, and repairs can be labor-intensive due to the car’s bulky layout and limited access under the hood. Additionally, its higher-than-average oil consumption means more frequent top-offs and potential long-term engine wear. While the car offers comfort and power, owners often find themselves making repeated trips to the shop, and not for routine maintenance.
2. Jeep Grand Cherokee
A favorite among SUV lovers, the Jeep Grand Cherokee also holds a reputation for being maintenance-heavy. From failing powertrain control modules to leaky differentials and persistent electrical gremlins, the Grand Cherokee racks up repair bills quickly once it’s out of warranty. Mechanics often mention that its off-road capabilities contribute to wear and tear that the average daily driver wouldn’t see. Replacement parts—especially for four-wheel-drive components—can be particularly pricey. Despite its rugged image, it’s one of those expensive American cars to maintain that might leave you second-guessing your next adventure.
3. Cadillac CTS
Luxury meets high upkeep when it comes to the Cadillac CTS. Mechanics frequently cite the CTS for its problematic timing chain system, which, if ignored, can lead to catastrophic engine failure. Other common issues include transmission failures, wheel bearing wear, and unreliable electrical components. Since it’s a luxury model, both parts and labor costs are inflated compared to standard sedans. Even minor repairs—like replacing a headlight assembly—can cost hundreds of dollars. If you’re drawn to the CTS for its performance and premium feel, be ready for premium-priced repairs, too.
4. Ford Explorer (Early 2010s Models)
The Ford Explorer, particularly models from the early 2010s, has been a headache for both owners and mechanics alike. These vehicles are known for timing chain tensioner issues, faulty water pumps buried inside the engine, and chronic transmission problems. Mechanics often say that just diagnosing these issues can be time-consuming and expensive, not to mention the actual repair itself. Labor costs skyrocket due to the complexity of engine teardown procedures needed for what would be a minor fix in other vehicles. It may have been a family SUV staple, but it certainly earned its place on the list of expensive American cars to maintain.
Before You Buy, Ask a Mechanic—Not Just the Dealer
When it comes to choosing your next car, don’t just consider the purchase price—think about what it’ll cost you over the next five years. Many of the expensive American cars to maintain have loyal followings because of their style, comfort, or performance. But what the brochures don’t show are the parts bills, service hours, and stress that come with ownership. The smartest move? Talk to a trusted local mechanic before buying. They’ll tell you what owners actually experience—and what you’ll likely spend.
