Protect My Car Highlights 

Protect My Car offers three different extended auto warranty plans for vehicles. Protect My Car stands out because it has high customer satisfaction ratings, which is fairly unusual for the extended warranty industry. This is why we gave it the Best Customer Service designation in our extended auto warranty industry review.

CarShield Highlights 

CarShield can be a smart choice for drivers on a budget, which is why we named it Best Monthly Payments in our extended warranty review. The company offers six comprehensive plans that can protect your vehicle up to 300,000 miles. It is also one of the only top companies to provide coverage for specialty vehicles like ATVs and motorcycles.



Protect My Car Vs. CarShield: Coverage

In terms of coverage plans, CarShield offers drivers more choices than Protect My Car. We’ll break down different plan options from both providers below. 

Protect My Car Extended Warranty Options 

Protect My Car offers three basic levels of coverage to drivers, specifically targeting new and high-mileage vehicles. Here’s an overview of the different vehicle protection plans available: 

  • Supreme: This is the highest level of coverage offered by Protect My Car, and it’s designed for newer vehicles. The plan covers most car parts, and drivers only have to pay a $100 deductible for covered repairs. 
  • Select: This warranty coverage option is available for vehicles with more than 50,000 miles. The coverage plan protects most vehicle parts except the turbocharger and navigation. Drivers have to pay a $200 deductible for car repairs. 
  • Driveline: This plan protects vehicles four to 10 years of age with more than 80,000 miles. Drivers receive 5 years/125,000 miles of coverage, whichever comes first. Most major vehicle parts are covered in case of mechanical breakdown except the front and rear suspension, select brake components, the turbocharger, and the navigation. Drivers have to pay a $200 deductible for repairs. 

CarShield Extended Warranty Options 

CarShield offers six comprehensive plans for drivers to choose from, including two powertrain warranty plans, which Protect My Car does not offer. Here’s an overview of CarShield’s warranty plans: 

  • Diamond: This plan is similar to a new car warranty and protects all systems and components except those not explicitly mentioned. 
  • Platinum: This is CarShield’s best option for vehicles with higher mileage. It protects your vehicle’s engine, transmission, air conditioning, electrical system, starter, water pump, and fuel pump. 
  • Gold: This warranty plan offers enhanced powertrain coverage for your car’s transmission, water pump, alternator, starter, and air conditioning. 
  • Silver: This basic powertrain coverage protects your vehicle’s engine, transmission, and water pump. 
  • Aluminum: This specialty plan covers most electrical and computer-related systems, including the engine control module, starter, alternator, navigation/GPS, and electrical system. 
  • Motorcycle & ATV: This coverage option protects your motorcycle or ATV. 

Additional Plan Benefits 

In addition to the various coverage options offered by Protect My Car and CarShield, both companies also provide the following benefits:

Protect My Car Vs. CarShield: Cost

Our team reached out to Protect My Car and CarShield to find out which offers more affordable bumper-to-bumper warranty coverage. The companies provided the following quotes for a 2018 Honda Civic with 30,000 miles and a $100 deductible:

Term Length

Monthly Cost

Total Cost

Based on the pricing we received, CarShield’s Diamond plan is cheaper than Protect My Car’s Supreme plan for bumper-to-bumper coverage. Both companies offer monthly payment plans for most extended warranty coverage options.

Note that you should use these estimates as a general idea for coverage since actual costs depend on multiple factors like the age of your vehicle, mileage, and where you purchase coverage.

Top Recommendations For Extended Car Warranties

While both Protect My Car and CarShield ranked in the top five of our best extended car warranty providers, we recommend reaching out to Endurance and CARCHEX for warranty quotes as well. 

Endurance: Best Coverage 

Endurance is a direct provider, meaning it creates and backs its own plans. This differs from other companies that use an intermediary like a dealership to sell their products. Endurance warranty coverage plans include six levels of coverage that can last beyond 200,000 miles. The company also offers 1 year of Endurance Elite Benefits for free, which includes:

  • Roadside assistance 
  • Total loss protection
  • Collision discount
  • Key fob replacement
  • Tire repair/replacement
  • Endurance mobile

Most drivers also find Endurance’s plan options affordable. A reliable car still under its factory warranty can get six years of exclusionary coverage for around $2,850, which is average compared with other estimates we received from third-party providers. Drivers can also choose from four different deductible plans.

CARCHEX: Best For Used Cars 

CARCHEX offers five warranty plans for drivers that can cover up to 250,000 miles, which is why we named it Best for Used Cars in our extended car warranty review. The company offers exclusionary coverage, high stated-component coverage, and several powertrain plans. 

CARCHEX plans are affordable for most drivers. The company provided us with a quote of $2,570 for seven years of exclusionary coverage, which is average among top extended warranty providers.
