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.

I owned my Lexus RX 350 for a couple of months before I unfortunately totaled it in an accident two weeks ago. While driving home on the freeway using smart cruise, a car suddenly changed lanes into mine, causing my car to hit theirs. Despite the smart cruise maintaining a safe distance from the car in front, my Lexus failed to come to a full stop before the collision. I was surprised by this, as my previous experience with a non-luxury SUV had been positive. After researching, I discovered that the Lexus RX 350 has a longer stopping distance than other luxury cars. I now know that the RX 450h is much heavier than the RX 350, and I suspect that they may have different brake systems. Best of luck to all Lexus RX 450h owners!

The seamless shifting between gears is pretty cool, and now I feel like I could never go back to a non-sports car with pronounced shifting. The seats and leather are as comfortable as I've come to expect from Lexus. I really appreciate the data screen that shows how the vehicle is being powered at any moment, be it the engine or the electric motors, or both, and when the batteries are being charged. In my last Lexus, the manual shifting was accomplished via the gear stick, so the paddle shifters are a neat thing to me, although I don't use them much. I thought I would use CarPlay more, but I enjoy using Google Maps via CarPlay, and otherwise prefer using my device by Bluetooth and utilizing the large 12.3

This SUV is incredibly well constructed and composed. It's exactly what you would expect it to be, with no surprises. The CVT coupled with the Hybrid System provides smooth and adequate power, while the ride is very comfortable. It's a heavy and well-made car, yet fairly agile for its size. Lexus has done an excellent job with this vehicle. While there may be certain aspects of the car that are not as nice as other competitors in the segment, on average, this car does everything very well. I highly recommend it!

The RX 450h F Sport has really comfortable seats, good handling, and amazing MPG. I drive a city-freeway combo daily and don't drive like a bat out of hell, and I average 25 mpg. I think this is good for such a heavy vehicle on 20-inch stock wheels. I went from a CT200H to this and can't complain, other than the CT had really good MPG.

The RX 450h is a smooth and quiet ride, even when accelerating! The transition is great and it offers excellent fuel efficiency. I was considering the GLC or GLE, but ultimately chose the RX 450h due to its exceptional comfort for both front and rear passengers. I upgraded to the premium version, which offers a better interior, audio, and larger wheels. Although it was slightly over my original budget, it was definitely worth it. While I have only owned it for 4 months, I am very satisfied with my purchase.

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.

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.

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.
