Common 2020 Lexus Rx450h problems

The Lexus RX 450h, a hybrid luxury crossover SUV, has been praised for its low emissions and excellent fuel economy. However, it is not without its common problems. Here are some of the issues reported by owners of the 2020 Lexus RX 450h:

  • Shock Absorber Failure: The Lexus RX 450h is a heavy car, which puts a lot of pressure on the suspension. This can lead to shock absorber failure. The shock absorbers may wear out quickly, especially if the vehicle is driven roughly or frequently on uneven roads.
  • Flat Battery: Some drivers report that the battery of their RX 450h goes flat after two to three weeks of not being used. This is especially inconvenient in a hybrid car because the battery can’t be jump-started. Instead, it has to be trickle charged, or the circuits in the hybrid system will be damaged. This usually means you have to call out a breakdown service.
  • Suspension Problems: The RX 450h models are fairly heavy and often develop suspension problems. Some owners report leaks in the system, while others report the compressor wears out quickly and has to be replaced.
  • Alloy Wheel Corrosion: The alloy wheels on the RX450h are known for suffering from premature corrosion and excessive wear of the surfaces of the wheel. As you inspect each wheel, the ones with this problem will need to be refurbished, in order to get them looking good again. You will also need to remove any corrosion.
  • MP3/Audio Player Problem: The audio unit mounting may become loose, causing the MP3/Audio player to cut out when driving over speed bumps or roughly surfaced roads. The mounting will need to be either fixed or replaced, and the audio unit re-fitted.
  • Rear Window Wiper Problem: Some owners report a rattling sound coming from the rear of the vehicle, caused by a problem with the wiper mechanism. The rattling sound happens when the faulty wiper knocks against the rear spoiler. You will need to replace the wiper mechanism, in order to resolve the issue.

In conclusion, while the Lexus RX 450h offers many benefits, it is not without its common problems. These issues, ranging from shock absorber failure to flat batteries and suspension problems, can affect the vehicle's performance and reliability. Therefore, it is essential to be aware of these problems and address them promptly to ensure the vehicle's longevity and safety.

Negative 2020 Lexus Rx450h car reviews

  1. Reuben Batz 2024-08-26

    Overall, this car has many positive features. However, we would not purchase it again due to two major issues caused by the extremely raked front windshield. Firstly, we recommend taking a test ride in the morning or evening when the sun is low. On even moderately warm days, the large windshield creates a greenhouse effect, making it feel like you're sitting in a glass hothouse with a small AC unit blowing cold air on you. While the air feels good, the sun is blasting your entire torso. Secondly, the wide slanted pillars block pedestrians and side traffic to a dangerous extent. Another issue is the engine. It's disappointing that a hybrid car requires premium gas, which goes against the idea of lowering gas prices. While some reviews claim that premium only costs 10c more, in California, it's 40c more. Despite these issues, the car has many positive attributes such as great seats, sound system, and AWD. The tech interface is also elegant and well-designed, which is a plus.

  2. Burley Legros 2024-07-04

    This car performs similarly to a Civic despite having only 4 cylinders. Although I experienced some issues with the emission filter during the first weekend, the service team attributed it to an overfilled gas tank, which I find hard to believe. Additionally, the car keeps beeping and asking me to clean the sensors in the rain, even though the car is clean. The navigation system and menus could use some improvement, and there has already been a software recall. However, I am hopeful that these issues will be resolved in the future.

  3. Major Lockman 2024-06-11

    I've had this car for over two years now and leased it. Despite some issues with quality, recalls, and cargo space, I'm glad I leased it because I won't be purchasing this SUV after the lease is up. This is my first Lexus and I was expecting better quality, but unfortunately, I've had some problems. Some of the issues I've faced include crappy tires that only lasted 20K, sunroof issues, and a broken driver side door latch. However, the car does have some good features such as being very quiet, having lots of tech, and a good sound system. The safety features are also great and the display and back up camera are very helpful. Although the car has some cons, it is still very comfortable to drive. I'm concerned about the reliability of this vehicle, so I'll be looking for a replacement come summer.

Positive 2020 Lexus Rx450h car reviews

  1. Pietro Schuster 2025-03-28

    You'll love the comfortable and quiet ride of this luxurious car. While the controls can be a bit annoying, the voice activation feature is a big help. If you're looking for even quieter tires, consider replacing the originals with Michelin. It's worth noting that the mileage may be lower in the winter or cold weather, but overall this is a great car to drive.

  2. Alan Cole 2025-03-24

    I shopped for months for a larger family SUV and finally found the perfect one in the RX 450h. It offers unparalleled comfort, space, and fuel economy that I couldn't find in any other car in the market. The driving experience is solid and substantial, with effortless steering and acceleration, and great visibility thanks to the A pillar and side mirror design. The hybrid powertrain works seamlessly and the car is whisper quiet at any speed. I highly recommend upgrading to the 12.3 inch infotainment system, which has a better input method with the joystick and a high-definition screen. On our first tank, we averaged 32 MPG with the AC on all the time, and speaking of which, it is the best AC system I have experienced in any car. It works in conjunction with the heated/ventilated seats and cools the cabin incredibly fast and super quietly. Overall, I have no negatives or complaints so far, and I highly recommend this excellent luxury mid-size SUV!

  3. Oran Satterfield 2025-03-01

    Beauty, quiet, great handling, beautifully displayed controls with an impeccable interior quality and design. With a constant MPG of 29 in city driving and all-around luxury, this Lexus RX450h is truly beyond compare to anything on the road. I have driven them all, and this car pulls away as the total champ.

  4. Roderick Heaney 2025-02-18

    I've been driving my RX450h F Sport for about 8 months now and have covered 8,500 miles. I decided to go with the same color combination (Atomic Silver with Rioja Red) as my previous car, a 2015 IS 350 F Sport, which I loved. This is my first hybrid and my first vehicle with a CVT, and I'm leasing it. When I test drove the RX Hybrid, I was impressed by how smooth and quiet it was. If you're considering an RX, I recommend trying both the 350 and the 450h. The RX is a reliable, sleek Lexus that is affordable compared to its competitors and has a low cost of ownership. Lexus reduced the price of the Hybrid for 2018, and when I compared a fully loaded 350 vs. 450h, the hybrid was only about $1k more. My RX has every option, including a 12-inch navigation package, Mark Levinson sound, parking assist, 360 camera, tribeam headlights, panoramic roof, and tow prep package. Here are some pros and cons based on my experience: Pros - Smooth and quiet ride - F Sport adds a little more fun around corners - Red interior is gorgeous - Plethora of safety features - More than enough acceleration power for typical drivers - Tribeam headlights are fantastic and the package comes with headlight washers, cornering lights, and self-leveling height - Extremely helpful 360 camera is a must-have (my favorite feature) - Lexus reliability and customer service. Cons - Driver's side exterior mirror shakes - F Sport seats have heavier side bolsters, which show wrinkles quite a bit - F Sport (and regular) seats show creases on the seat bottom pretty easily. Overall, I highly recommend this generation RX!You really can't go wrong, especially considering the few gripes I have.

    This car is smooth, luxurious and just looks amazing. I'm so glad you're happy with it!
