Is the Toyota 4RUNNER more reliable than the Chevrolet Blazer?

Yes, by a slight margin. The 4Runner's reliability standing is excellent and the Blazer's is good. Owners filed 1.5 complaints per 10,000 4Runners sold against 2.1 for the Blazer. The Blazer does need fewer unscheduled shop visits, so the two are closer than the standings alone suggest.

Which has more recalls, the 4Runner or the Blazer?

The Blazer has slightly more. Federal recall records show 19 recalls across 8 Blazer model years and 17 across 9 4Runner model years. Per model year, the Blazer's load is heavier. Check any specific vehicle's VIN for open recall work before you buy.

Which is cheaper to repair, the 4Runner or the Blazer?

They cost almost the same. Independent repair-cost data puts the 4Runner at $514 a year and the Blazer at $521. Over five years that is about $35 apart. The bigger difference is the type of failure, since Blazer owners report transmission replacements and repeat radiator jobs.

What goes wrong with the Chevrolet Blazer transmission?

Reports cluster around 82,000 to 84,000 miles. Owners describe jerking, a roaring noise with metal in the fluid, and sudden loss of drive at highway speed while the engine revs. Several ended in a full transmission replacement. Some cars shuddered from a stop up to 40 mph beforehand.

Why does the 4Runner shake at highway speed?

Owners report a shaking and wobbling through the steering wheel, usually between 50 and 70 mph. Balancing, rotation, new tires and alignment checks often do not cure it. One dealer pointed to a possible steering rack issue. It is worth testing at those speeds before you buy.

Chevrolet Blazer vs Toyota 4Runner: Reliability Compared

Chevrolet Blazer

Good

More Reliable

Toyota 4Runner

Excellent

On reliability, the Toyota 4RUNNER edges the Chevrolet Blazer, with fewer owner complaints per vehicle sold and a slightly lower repair bill. The gap is slight. The Blazer's transmission failures and recurring coolant temperature faults are the main reason it trails.

How Do the Chevrolet Blazer and Toyota 4Runner Generations Compare?

Most used 4Runners you are likely to see, 2018 through 2024, belong to the fifth generation, which ran from 2010 and received a facelift in 2013. A sixth generation (N500) began with the 2025 model year, so 2025 and 2026 models are the newest design and have had little time to collect complaints. The Blazer is a crossover that was reintroduced for 2019 and sits in its third generation, listed here through 2023. Its used market is all recent years. A separate Blazer EV generation appears in the data for 2023 only.

Verdict

The Toyota 4Runner is more reliable than the Chevrolet Blazer, scoring 80/100 vs 76/100.

Reliability favors the 4Runner by a slight margin. Its standing is excellent against good for the Blazer, and owners filed fewer complaints per vehicle sold, 1.5 per 10,000 versus 2.1. Repair costs are nearly identical, so the gap is not wide. The Blazer's complaints center on transmission failures and a coolant temperature fault that spills into steering and electrical warnings. The 4Runner's lead complaints are a highway-speed shake and brake noise. The Blazer does have fewer unscheduled shop visits, which keeps this close.

What Are the Common Problems With the Chevrolet Blazer and Toyota 4Runner?

Power train trouble sets the Blazer apart. Transmissions fail around 82,000 to 84,000 miles, with jerking, metal in the fluid, or sudden loss of drive at highway speed. Cracked radiators and a coolant temperature fault also trigger "Steering Assist Reduced" warnings and a fan that runs after shutdown. The 4Runner's top complaints are a wheel shake between 50 and 70 mph that shops often cannot cure, and brake squeaks. Its air bag area has 20 crash-linked complaints, including front bags that did not deploy. The Blazer has five crash-linked brake complaints, against one for the 4Runner.

Who Should Buy the Chevrolet Blazer vs the Toyota 4Runner?

Pick the 4Runner if you plan to keep the vehicle for years and want the better reliability standing. Owner complaints run lower per vehicle sold, and the main issues are annoying more than disabling. Target 2021, one of its strongest years, and be wary of 2018 and 2019, its weakest. Test drive between 50 and 70 mph to check for the steering shake, and ask about air bag sensor history. Pick the Blazer if fewer unscheduled shop visits matter most to you and you can accept more risk of a big power train bill. Look for 2022, one of its strongest years, and avoid 2019 and 2024, its weakest. Have the transmission checked on any car in the 82,000 to 84,000 mile range, where failures cluster. Ask whether the radiator and coolant temperature sensor have been replaced, and run the VIN for open recalls. Check the brakes closely, since some owners report noise from almost new and a few report a hard pedal.
