When you’re shopping for a car, one of the biggest concerns is how long it’s actually going to last. While many brands promise reliability, some have earned a reputation for falling apart sooner than you’d expect. Knowing which car brands mechanics often see struggling to reach high mileage can save you money and frustration down the road.

Mechanics have hands-on experience with repairs and breakdowns, so their insights can be really valuable when deciding what to buy or avoid. This article looks at six car brands that tend to have the worst longevity, helping you make a smarter choice for your next vehicle.
Fiat
If you’re thinking about a Fiat, be prepared for mixed reliability. While they’re stylish and affordable, Fiats often come with recurring mechanical and exterior issues that can add up over time.
Many mechanics point out that Fiat models tend to struggle with longevity compared to other brands. If you want a car that lasts easily past 100K miles, Fiats might not be your best bet.
That said, some owners still appreciate Fiats for their design and fun factor, but just know you might face more frequent repairs than with other brands.
Jeep
If you’re considering a Jeep, be ready for some potential headaches down the road. Many mechanics agree these vehicles often struggle to hit 100,000 miles without major issues.
Common problems include transmission failures and electrical glitches, especially in models like the Wrangler and Cherokee. You might find maintenance costs higher than expected, so budgeting for repairs is a good idea.
While Jeep’s off-road chops are well-known, their reliability isn’t quite as impressive. If longevity is your priority, you might want to weigh your options carefully.
Land Rover
If you’re thinking about a Land Rover, be ready for some costly repairs. Mechanics often point out electrical issues and air suspension problems that come up frequently.
You might enjoy the luxury and off-road capabilities, but the maintenance bills can really add up. Over 10 years, owners spend thousands more on repairs compared to many other brands.
Keep in mind, Land Rover is often listed as one of the least reliable brands by experts. If longevity is key for you, this might not be the best choice.
Chrysler
If you’re thinking about a Chrysler, you might want to reconsider. Mechanics often point out that Chrysler vehicles tend to have frequent mechanical issues that can add up over time.
You could end up spending more on repairs than you expected. Parts wear out faster, and some models have well-known problems with reliability.
It’s not that every Chrysler will fail quickly, but if longevity is a priority for you, there are better options out there. Be prepared for potential maintenance headaches down the road.
Tesla Model S
If you’re thinking about a Tesla Model S, be aware that some older models have a rough reputation for longevity. Early versions, especially from 2012 to 2017, often face issues like battery and drive unit failures.
You’ll want to check service records carefully and test key features like the touchscreen and door handles. Newer Model S cars, from 2018 onward, tend to be more reliable and have fewer reported problems. That said, repairs can still get pricey, so keep that in mind if you’re budget-conscious.
Dodge
If you’re thinking about a Dodge, be ready for some potential headaches down the road. Mechanics often point to issues with reliability and frequent repairs, especially on older models.
You might experience problems with their engines and electronics, which can lead to costly visits to the shop. While Dodge has some strong performance models, the trade-off is usually in long-term durability.
So, if longevity is your priority, it’s a good idea to weigh these factors before choosing Dodge.
