Buying a car is one of the biggest financial decisions most people make, and reliability is key. While many vehicles cruise past 100,000 miles with minimal issues, others start falling apart, turning into money pits that drain your wallet. These cars may be popular for their style, features, or affordability, but once they hit that mileage milestone, hidden problems often surface. From transmission failures to electrical gremlins, the repair bills can quickly pile up. If you’re shopping for a used car or wondering whether to keep your current ride, this list could save you thousands.
1. Chrysler Town & Country

My wife owned one of these at one time, and it was a money pit over the several years she drove it. The Chrysler Town & Country is a family favorite thanks to its spacious interior and comfort features. However, once it crosses the 100,000-mile mark, it’s notorious for transmission issues and electrical system failures. Owners often report problems with the power sliding doors, faulty sensors, and expensive engine repairs. These recurring issues can make maintenance costs skyrocket, especially if you’re out of warranty. While it’s a smooth ride early on, it can become a financial burden in the long run.
2. Ford Focus

The Ford Focus has long been a go-to for budget-conscious drivers, but its reliability fades with age. After 100,000 miles, many owners face transmission problems, especially with models equipped with the PowerShift dual-clutch system. Electrical issues, stalling, and steering failures are also common complaints. These problems aren’t just annoying. They can be dangerous and costly to fix. Despite its popularity, the Focus often disappoints when it comes to long-term dependability.
3. Mini Cooper

Mini Coopers are beloved for their quirky design and fun driving experience, but they’re not built for the long haul. Once past 100,000 miles, they frequently suffer from turbocharger failures, oil leaks, and cooling system breakdowns. Repairs tend to be expensive due to the brand’s premium parts and labor costs. Owners often find themselves shelling out thousands just to keep the car running. If you’re considering a used Mini, be prepared for a pricey relationship.
4. Chevrolet Cruze

The Chevrolet Cruze is a compact car that gained popularity for its fuel efficiency and affordability. Unfortunately, it’s also known for engine and transmission problems that emerge after 100,000 miles. Coolant leaks, overheating, and turbocharger failures are common issues that can lead to costly repairs. Many owners report needing major work just to keep the car roadworthy. While it may seem like a smart buy upfront, the Cruze can quickly become a money pit.
5. Jeep Grand Cherokee

The Jeep Grand Cherokee is a stylish SUV with off-road capabilities, but its reliability takes a hit over time. After 100,000 miles, it’s prone to suspension problems, electrical failures, and transmission breakdowns. Repair costs are often high due to the complexity of its systems and premium parts. Owners frequently report issues with the air suspension and infotainment system, which can be both frustrating and expensive. It’s a great vehicle when new, but aging models can drain your bank account.
Mileage Isn’t Just a Number
Crossing the 100,000-mile threshold is a milestone, but it’s also a turning point for many vehicles. Some cars continue to perform reliably, while others start revealing their flaws. Knowing which models tend to become money pits can help you make smarter decisions, whether you’re buying used or deciding whether to keep your current car. Regular maintenance helps, but some issues are baked into the design and can’t be avoided. Do your research, and don’t let a popular name fool you into costly regret.
