Hybrid Battery Degradation

The lithium-ion battery pack in your Prius Prime is its lifeline. But it’s not immortal. Over time, it loses capacity. This affects your electric range and overall efficiency. The 2017-2021 models are particularly prone to this issue.

Signs of trouble? Decreased electric-only range. More frequent engine starts. Reduced fuel economy. Toyota’s warranty covers the battery for 10 years or 150,000 miles. But what if you’re outside this window?

Prevention is key. Avoid frequent fast charging. Don’t let the battery sit at extreme charge levels. Park in cooler areas when possible. If you suspect issues, get a battery health check. Our technicians at Fremont Foreign Auto can provide expert diagnosis and solutions.

EV System Overheating

Your Prius Prime’s electric vehicle system can overheat. This is especially true for 2017-2019 models. Hot climates and extended electric-only driving are common culprits.

Watch for reduced electric power output. Unexpected switches to hybrid mode. Warning lights on your dash. These are red flags. The root cause? Often insufficient cooling of the power control unit or electric motor.

Toyota has issued technical service bulletins for some model years. These recommend updates to the PCU cooling system. Regular maintenance is crucial. Use eco mode in hot weather. Consider aftermarket cooling solutions for severe cases. Our team can implement necessary fixes, including coolant system upgrades or PCU software updates.

Brake System Complications

The regenerative braking system in your Prius Prime is complex. It’s a key part of the hybrid efficiency. But it can cause headaches, especially in 2017-2018 models.

Feeling a spongy brake pedal? Noticing inconsistent performance? Seeing ABS or brake warning lights? These are signs of trouble. Air in the brake lines, faulty actuators, or brake booster issues are common culprits.

Regular maintenance is crucial. Have your brake fluid flushed and replaced on schedule. Pay attention to changes in pedal feel or stopping distance. Address warning lights promptly. Our specialists at Fremont Foreign Auto can diagnose and repair your hybrid brake system to ensure safety and efficiency.

Fuel Tank Capacity Discrepancies

Ever feel like your Prius Prime’s fuel tank is lying to you? You’re not imagining things. Some 2017-2019 models have reported fuel tank capacity issues. The advertised capacity is 11.4 gallons. But some vehicles only accept 5-6 gallons before the pump shuts off.

This problem reduces your overall driving range. It leads to more frequent refueling stops. Your fuel gauge may give inaccurate readings. The culprit? Often it’s the fuel tank design and filler neck positioning.

Solutions vary. Software updates can improve fuel gauge accuracy. Venting system modifications help. In some cases, fuel tank replacement under warranty is necessary. Our technicians can diagnose the problem and recommend the best fix for your specific situation.

Infotainment System Glitches

High-tech doesn’t always mean hassle-free. The Prius Prime’s infotainment system, especially in 2017-2020 models, can be glitchy. Touchscreen unresponsiveness. Bluetooth issues. GPS errors. System freezes. Sound familiar?

These problems stem from various sources. Outdated software. Hardware malfunctions. Device incompatibilities. Regular system updates are crucial. Perform resets when needed. Check for Toyota’s technical service bulletins.

At Fremont Foreign Auto, we can tackle these tech troubles. We offer software updates, hardware replacements, and wiring repairs as needed. Don’t let a faulty infotainment system ruin your driving experience.

Catalytic Converter Theft

This isn’t a vehicle flaw, but it’s a real threat to Prius Prime owners. Catalytic converters are hot targets for thieves. Your Prius Prime’s high ground clearance makes it vulnerable.

The consequences? Loud exhaust noise. Check engine lights. Reduced efficiency. Potential engine damage. Protection is possible. Install a catalytic converter shield. Park in secure areas. Consider VIN etching for identification.

We offer installation services for various protection devices designed specifically for the Prius Prime. Don’t wait until it’s too late. Protect your vehicle now.

12V Battery Drainage

Your Prius Prime has two batteries. The hybrid battery gets all the attention. But the 12V battery is crucial too. Some owners, particularly of 2017-2018 models, report rapid drainage issues.

Trouble starting your vehicle? Electrical system acting up? Warning lights on the dash? These could indicate 12V battery problems. The culprit is often the power management system failing to maintain proper charge.

Regular driving or charging helps. Get your 12V battery and charging system checked regularly. Consider a battery maintainer for periods of disuse. Our team can perform comprehensive diagnostics on your electrical system to identify and resolve any issues.
