Nice car and comfortable excellent SUV handling unlike others.
I do not have any problems with this vehicle. The car is comfortable and spacious. Very reliable and car comes with four years of sos for free so no need to pay extra for insurance. For the price is comfortable and big enough. Excellent handling for an SUV and handles curving very well.

Upgrades equal luxury vehicle.
I enjoy all the features within the car. The main thing that attracted to me to the vehicle are the standardized safety features. Most vehicles you have to pay extra for the safety features and once you add those on you end up paying 50-60k for a ford.

What Common Problems Does the 2021 Lexus RX Have?

Common problems found on the 2021 Lexus RX include premature brake wear, the stereo system freezing, along with some noise from the wheel hubs. Overall, these problems are minor for a luxury midsize SUV, leading to low repair bills as the RX ages.

Premature brake wear is the most widespread complaint on the 2021 Lexus RX, showing up in the first 20,000 miles. The front brakes in particular tend to wear down quickly, and the pads need to be replaced. Changing out the brake pads costs around $200. If there’s any wear to the rotor then they are roughly $400 for the front set.

The stereo system freezing is another issue that some owners report at around 1,500 miles. There are software updates available for the stereo system that improves its reliability. Most dealerships will install these updates for free, while some charge around $50.

Some noise from the front wheel hubs has also been reported on the 2021 RX at around 5,000 miles. Usually, the problem is just caused by a wheel bearing which could have had grease wear off. Inspecting and fixing wheel bearings can cost around $100, while a new bearing is around $350 installed.

There’s only one recall on the 2021 Lexus RX, which is better than many other SUVs on the market. The rear transport hook may damage the fuel filler pipe. Lexus will remove the hook on affected models for free.
