Does the Chevy Trax have engine problems?

[DeXavier]

The Chevrolet Trax has documented engine problems, but they are not universal. Issues are model-specific, primarily affecting the older 1.4L turbo and the newer 2024-2025 1.2L three-cylinder engines. While many owners report trouble-free operation, a significant number of complaints and a pending class-action investigation highlight reliability concerns for certain model years.

Key problems vary by generation. For the 2024-2025 Trax with the new 1.2L turbocharged three-cylinder engine, the most severe reports involve catastrophic engine failure, such as connecting rods breaking through the engine block. Other drivers note sudden stalling or loss of power. These issues have prompted a class-action lawsuit investigation into potential defects. In contrast, many 2024 owners have experienced no problems, with complaints representing a small percentage of the over 200,000 units sold.

Older models (pre-2023) with the 1.4L turbo engine commonly face different challenges. Turbocharger failure is a frequent and costly repair. Oil leaks from the valve cover and oil pan gaskets are also prevalent, which can lead to low oil levels and engine damage if unchecked. Additionally, cracked plastic intake manifolds cause vacuum leaks, triggering check engine lights and rough idling.

Common symptoms across affected models include unexpected stalling at idle or while driving, a noticeable lack of power during acceleration, unusual knocking or vibration from the engine bay, and in some older models, overheating. These symptoms often stem from failed sensors, fuel delivery issues, or the mechanical failures mentioned.

According to analysis of data from the National Highway Traffic Safety Administration (NHTSA) and consumer complaint platforms, the pattern of issues shifts with the model year. Market analysis from firms like S&P Global Mobility notes that while the new Trax has been a sales success, its long-term reliability ratings are still being established.

Model Year & Engine	Most Reported Engine Problems	Typical Symptoms & Notes
2024-2025 (1.2L 3-cylinder)	Catastrophic internal failure (thrown rod), sudden stalling.	Low incident rate overall but severity is high; under class-action investigation.
Older Models (1.4L Turbo)	Turbocharger failure, oil leaks (valve cover, oil pan), cracked intake manifold.	Problems often appear at higher mileage (60,000+ miles); can lead to secondary damage.

If you experience symptoms like stalling or loss of power, it is a serious safety concern. The immediate action is to safely pull over and have the vehicle towed to a certified technician for diagnosis. For oil leaks or check engine lights, avoid extended driving and seek professional assessment promptly.

For owners, checking oil level and condition regularly is crucial, especially on older 1.4L models. Using the correct oil specification and adhering to severe service maintenance schedules if you do frequent short trips can help mitigate some issues. Staying informed about NHTSA recalls is essential.

While the Trax offers value, potential buyers should weigh these known issues. A thorough pre-purchase inspection by a trusted mechanic for used models, especially those with the 1.4L engine, is highly recommended. For new models, being aware of the ongoing investigation and understanding your warranty coverage is key.

I owned a 2024 Trax for about eight months. Honestly, it was great until it wasn’t. One morning, it just lost all power on the highway and started making a horrible knocking sound. The dealership said the engine had thrown a rod—basically, it destroyed itself. They replaced the whole engine under warranty, no questions asked, which was a relief. But now I’m nervous. The car drives fine since the repair, but I’m constantly listening for new noises. I love the tech and space, but that experience really shook my trust. I’m following the class-action news closely.

As a mechanic who sees a lot of these in the shop, the Trax story has two chapters. The old 1.4L turbos? We replace turbos and seal oil leaks constantly once they hit around 70,000 miles. The plastic intake manifolds crack like clockwork. Telltale signs are a check engine light for a lean code and a whistling sound.

The new 1.2L three-cylinder is a different beast. We haven’t seen many for routine service yet—they’re too new. But the few we have seen with major problems are dramatic. Complete engine seizures. It’s not a high-volume problem percentage-wise, but when it happens, it’s total failure.

My advice for any Trax owner: be religious about oil changes with the exact oil GM specifies. For 1.4L owners, check your oil level every other fuel fill-up. That early warning can save you a huge repair bill.

If you’re comparing the Trax to rivals like the Honda HR-V or Hyundai Kia Soul, reliability history is a key factor. The Trax’s main issue is its inconsistent engine track record. The previous generation’s 1.4L had known, widespread issues. The new model’s engine is too new to have a long-term reliability score from sources like Consumer Reports or J.D. Power.

The competition often uses naturally aspirated engines that, while less powerful, have a longer history of proven durability. When shopping, a lower purchase price shouldn’t be the only consideration. Factor in the potential risk and the strength of the warranty. Hyundai Kia’s 10-year powertrain warranty, for instance, offers longer peace of mind than GM’s standard coverage.

We’ve had our 2017 Trax for seven years and 85,000 miles. Yes, we’ve dealt with the classic oil leak from the valve cover—it was a $400 fix at our independent shop. And just last year, the turbocharger started failing; we could hear it whining. That was a tougher repair, costing us about $1,800.

Despite that, I don’t regret the purchase. It’s been a practical, affordable car for our family. The key is going in with eyes open. We budget for repairs, knowing its weak points. We’re more diligent with maintenance than we were with our old Camry.

For someone considering a used one, I’d say only buy it if you can get a great deal and you have a mechanic check it thoroughly for oil leaks and turbo health. For a new one, the warranty is your best friend for the first few years while the new engine’s reliability is proven.
