Lexus Rx400h problems

The Lexus RX (Japanese: レクサス・RX, Hepburn: Rekusasu RX) is a luxury crossover SUV sold since 1998 by Lexus, a luxury division of Toyota. Originally released in its home market of Japan in late 1997 as the Toyota Harrier, export sales began in March 1998 as the Lexus RX.

Considered as the first luxury crossover SUV, five generations of the RX have been produced to date, the first being compact in size, and the latter classified as mid-size. Both front- and four-wheel drive configurations have been used on the RX series, and several gasoline powertrain options, including V6 engines and hybrid systems, have been offered. In the Lexus model lineup, the RX sits below the larger Lexus LX (marketed as the Toyota Land Cruiser body-on-frame SUVs outside North America, respectively), and above the shorter and less wider, but taller GX SUV. The name "RX" stands for "Radiant Crossover". It has also been labelled as "Recreational Cross Country" in some markets. The RX's current Toyota counterpart is the Highlander/Kluger; past counterparts included the Harrier and Venza.

The first-generation RX 300, fitted with a 3.0-liter V6 engine, began sales in 1998. The Japanese market Harrier released in 1997 also offered a 2.2-liter inline-four, later uprated to 2.4 liters. The second-generation RX 300 (3.0-liter V6) and RX 330 (3.3-liter V6) models went on sale in 2003, with both variants supplanted by the more powerful RX 350 (3.5-liter V6) in 2006. Like the previous series, a 2.4-liter inline-four engine was sold alongside the 3.0-liter V6 in the Japanese market Harrier. In 2005, a hybridized gasoline-electric version of the 3.3-liter second-generation model was made available as the RX 400h in export markets and as the Harrier Hybrid in Japan. For the third generation released in 2009, both RX 350 (3.5-liter V6) and RX 450h (3.5-liter V6 hybrid) models were initially offered, with an entry-level RX 270 (2.7-liter inline-four) offered by Lexus in some Asian markets, including in Japan, since 2010. Since the release of the third generation, Japanese sales have occurred under the RX name as opposed to Harrier as had been the case previously. In the fourth generation, a turbocharged (2.0-liter inline-four) RX 200t/300 model was introduced to replace the previous 2.7-liter unit.

The RX has been assembled at Toyota Motor Kyushu since launch. The RX and RX Hybrid were the first Lexus models to be built outside Japan, with North American market versions produced at the Toyota Motor Manufacturing Canada plant in Cambridge, Ontario beginning 2003 (RX) and expanded in 2014 (RX Hybrid). Hybrid transaxles are built at the Kokura plant in Kitakyushu, Fukuoka since 2009.

Latest negative Lexus Rx400h car reviews

  1. Blaze Ullrich 2025-02-25

    Vehicle year: 2006

    When we first got this car, we were absolutely thrilled with it! It's a fantastic, comfortable family car that's perfect for long journeys, and it's also a much greener option for the city. While we knew that the fuel economy wasn't going to be amazing, the fact that we weren't churning out fumes in slow-moving traffic was a huge plus. (I walk a lot in town and hate going past slow-moving traffic with my kids - it stinks!) Unfortunately, after a few months, we started having trouble with the car not starting. We tried new batteries, but the problem persists. We've done some internet searches and it seems like many others are having the same issue. We were disappointed with the unhelpful response from Lexus.

  2. Jovany Trantow 2025-01-23

    Vehicle year: 2006

    I love my Lexus RX 400h and have driven it for 98,000 miles. However, I have been experiencing some frustrating service problems lately. The cruise control, battery, and radiator have all needed repairs, and just yesterday the timing belt, pulleys, and water pump had to be replaced at Lexus' request, costing me over $2500 in less than a year. As an owner of a first-year model in this series, I wonder if these issues are common or if it's just my SUV. Can anyone relate?

  3. Bobby Douglas 2025-01-17

    Vehicle year: 2008

    Hello! I hope you're doing well. I wanted to share my experience with my Lexus RX400h. I noticed that there was an issue with the brake actuator in these models that could potentially deactivate the brakes at any time. I called Lexus in July 2016 to report that while driving on the freeway, my ABS VCS light went on, I heard a high pitched sound that went on continuously and I lost my brakes. I was with my 8-year-old daughter at the time, and it was a very scary experience for both of us. When I called Lexus Jim Falk Beverly Hills service department, they suggested that I turn off the engine and wait a few minutes because the ABS needs to reset. This happened to me three more times, and I followed the same procedure each time. However, just last week, I was driving my pregnant wife to the doctor, and this issue happened again, and we almost hit the car in front of us. I immediately brought it to Longo Lexus service department, and they told me that my brake actuator needed to be replaced, which would cost me $4,000 to fix. They also informed me that this is a known issue with the Lexus RX400h and that there was a campaign that replaced these for free in 2016, which had expired on December 31, 2017. Unfortunately, I missed the deadline. I called Lexus corporate office and explained my situation, but they said that there was no proof that the car lost its brakes because no one inspected it at that time. I was shocked when they suggested that I drive a car with no brakes to a Lexus dealer that was 10 miles away. I hope that Lexus can address this issue and ensure the safety of their customers. Thank you for listening to my story.And you know what? I trusted you when you said this was a common issue, because you're Lexus! But now you're asking me to pay $4,000 for your mistake? It's frustrating, and it makes me hesitant to recommend Lexus to others. It seems like safety isn't a top priority for them.

    Hi there! I noticed that my RX400H only gets 20 MPG City. Also, when going over wider speed bumps with a small amount of loft, it sounds as if the engine is dropping out of the car with a loud bang. Additionally, there is mild steady vibration at times that can be felt in the steering wheel and seat armrest. I found the instrumentation to be a bit confusing, especially the cruise control which is on its own lever and moves with the steering wheel, making it difficult to access when turning. Have you experienced any of these issues?

    After conducting extensive research on major automotive periodicals, I purchased a Lexus with high expectations. However, the vehicle did not meet my expectations as I was initially promised a fuel consumption rate of 38 mpg in town and 32 mpg on the highway, which was later changed to 32 mpg in town and 29 mpg on the highway with an average of 30+. Despite waiting until the vehicle had 5k miles, my overall average is a disappointing 24 mpg. Additionally, I experienced an issue with the windscreen fracturing without any impact, which was not repaired until I threatened legal action. Overall, my experience with this purchase has been unsatisfactory.

    I was searching for a reliable and affordable SUV hybrid that wouldn't break the bank. I found exactly what I was looking for in this used vehicle. It meets all my needs in terms of safety, reliability, comfort, and low mileage for a 10-year-old model. It looks just as good as newer SUVs on the market. Although the fuel economy is not as impressive as advertised online, averaging only 24.5 city:highway, I still find it to be a great ride. The navigation system can be a bit wonky at times, with the arrow and roads on the screen tracking the vehicle's direction in a confusing way. However, the vehicle's handling and styling are exactly what you would expect from a quality luxury vehicle. The Bluetooth works well for calls, but unfortunately doesn't project directions from phone through SUV speakers when using other GPS apps like Google Maps or Waze. Overall, I'm very happy with my purchase and would highly recommend this vehicle to anyone looking for a reliable and stylish ride.

    I have loved this car since the day we bought it new. With nearly 80,000 miles on the clock, I have no complaints, except for some paint chips on the door edges. Despite this, I have no intention of buying a new one due to my dislike of the new design and screens. The new model uses a mouse instead of touch screens, which I find to be a step backwards.

    I was so excited to buy a hybrid this year! I wanted to make sure it would last until the market opens up even more for alternative fuels. Right now, I'm getting about 30 mpg, which is almost 2-1/2 times what I got with my previous vehicle. I absolutely love it! Bravo Toyota!

    You're doing great! We're so glad to hear that you're enjoying your car. It sounds like it's been a reliable and efficient mode of transportation for your daily commute. With 28 MPG, you're definitely getting your money's worth. Plus, the gearless transmission makes for a smooth ride. It's great to know that Lexus provides the first 2 maintenance free, and with the batteries warranted for 9 years, you can rest easy knowing that you're covered. Keep up the good work!

    This is my second RX series AWD. I love how reliable, comfortable, and stylish it is. The car is perfect for both long trips and driving around town. The brakes are the best I have ever experienced, especially in rainy Florida weather. Additionally, the car has amazing pickup, which is extremely important when entering some of the unavoidable interstate highways. I also appreciate the quiet engine of this hybrid. I am already looking forward to my next Lexus!
