Common Lexus Nx300h problems
Common Problems with the Lexus NX300h:
- Engine Overheating: The Lexus NX300h may experience engine overheating due to a faulty thermostat or radiator fan. This issue can cause the engine to run at higher temperatures, potentially leading to damage to other engine components. If the engine overheats, it is important to pull over and allow the engine to cool down before continuing to drive.
- Brake Problems: Brake issues in the Lexus NX300h may include a spongy brake pedal, reduced brake performance, or unusual noises when braking. These issues can be caused by worn brake pads, damaged brake rotors, or a malfunctioning brake system. Regular maintenance and inspections can help identify and address brake problems before they become more serious.
- Suspension Issues: The Lexus NX300h may experience a noticeable bounce while driving, especially when turning a corner. In some cases, the vehicle may even lean to one side, indicating a misaligned suspension. Furthermore, the vehicle may feel unstable when driving over rough terrain or may become excessively bouncy, even on smooth roads. This issue is usually caused by worn shock absorbers, which can be replaced with new ones. Additionally, the suspension bushings may need to be replaced if they are worn out.
- Transmission Problems: One of the most common complaints about the Lexus NX300h is its jerky and surging acceleration. This problem is caused by an issue with the vehicle’s continuously variable transmission (CVT). The transmission is designed to constantly adjust the engine’s power output to optimize fuel economy. However, when the transmission is unable to adjust properly, it can cause the engine to jerk and surge, resulting in a rough and uncomfortable ride. Other common transmission problems in the Lexus NX300h are hard shifting and slipping.
- Electrical System Problems: The Lexus NX300h is known to have problems with its electrical system, including the battery and starter. In some cases, the power steering pump may fail, which can cause the steering wheel to be slow and unresponsive. Other problems include noise coming from the power steering system, a malfunctioning electric power steering system, or a malfunctioning steering wheel position sensor.
- Engine Problems: The engine in the Lexus NX300h can experience problems with the spark plugs, fuel injectors, and timing chain. Spark plug issues might be caused by poor maintenance, or a bad spark plug. Fuel injector issues are usually a result of a faulty fuel injector or a clogged fuel filter. The timing chain might become stretched, which can cause the engine to misfire. Another frequent problem with the car engine is rough idle. This problem is caused by some factors, including a faulty idle air control valve, or a vacuum leak.
In summary, the Lexus NX300h is a reliable vehicle, but like any car, it can experience common issues that impact its reliability and performance. These issues can range from minor to major, depending on the severity of the problem. Some common issues include brake problems, suspension issues, transmission problems, electrical system problems, and engine problems. Fortunately, most of these issues can be solved relatively easily with the help of a qualified technician by simply replacing worn parts or components.

- Summary: The sunroof glass suddenly shattered, for no apparent reason and without warning. There was no collision and no impact by an object. We were driving at freeway speed when we heard a loud bang above our heads. The interior sunroof cover was closed at the time. I slid it partway open and saw that the glass of the sunroof had shattered, so I closed the cover to keep glass from falling in the car. Had it been open at the time of break, the glass would have rained down on the driver and passenger. I have not yet taken it to a dealer or repair shop.

- VIN: JTJYARBZ2J2
- Components: FUEL/PROPULSION SYSTEM
- Summary: I was driving on 64 and at a sudden my 2018 NX 300 stopped accelerating and engine was stalled. I was lucky that the highway was not busy, so I was able to park it on the shoulder of HWY and later towed it to my home. The car was not drivable anymore as engine was keep shutting down with the warning and engine lights. The code on the screen was P0087 - Fuel Rail/System Pressure - Too Low. It seems that the fuel pump mall function. I research online and noticed, that others also reported the same issue related to Fuel pump failure on this model. Also, on further research, I found that Lexus recalled this model along with other models for the same issue. But when I check my VIN then it shows that my VIN has no recall related to Fuel Pump mall function. Not sure why my VIN is not included in the recall even though this model and year has a recall for this issue.
Lexus Nx300h 2015
- Date Of Incident: 2022-02-01
- Date Complaint: 2024-04-15
- VIN: JTJBARBZ4F2
- Components: POWER TRAIN
- Summary: Since I am just finding out how to file a complaint I figured I would. I still have this car with me. The incident happened about 2 years ago. I was driving down the highway going to Castle Rock Colorado. When all of a sudden my car is thrown into neutral and my rpms go to 6,000. I had no way to accelerate and the car wasn't in gear to help decelerate . Since I was going down the highway at a high rate of speed trucks and cars were all around me.. I immediately turned on my four ways and pulled the car over to the side of the highway. As there was nothing wrong with the motor and it seemed like it was just with the transmission I. Decided to continue but as I continued when I got to 4 gear it would once again throw it out of gear and I couldn't accelerate and I had to pull over. At this point I knew something was wrong. I immediately got the car to a safe area and got it home and the next day got the car to the mechanic. The mechanics said that I needed a new transmission 4 gear is just missing. When the mechanic was putting back together. The very expensive $7,345.00 transmission. He got the parts directly from Lexus and when he went to test, drive the car with the same but new components the transmission immediately failed again, not allowing him to shift in the 4 gear and stalling the car putting him in danger on a busy road. When he got back to his shop he called back to Lexus to verify that the parts that he was given were correct. They verified that the new parts he was given are the old design and that he needed upgraded newer parts that lexus has designed and should have never gotten the other ones . At this point he got the proper parts again and for a second time put the upgrade parts in and it worked . By Lexus not giving the mechanic, the proper upgraded parts. Not only did they put me in danger with the part breaking the first time on the highway they put the mechanic in danger by not giving him the upgraded parts the first time ... thank you
Lexus Nx300h 2015
- Date Of Incident: 2023-09-25
- Date Complaint: 2023-10-03
- VIN: JTJBARBZ2F2
- Components: POWER TRAIN,ENGINE
- Summary: I purchased this vehicle in 2015 - it has been dealer serviced and has never been in an accident. At just under 90,000 miles on the odometer, a major fluid leak started. It turns out that the rear main (crankshaft) seal had failed, causing a leak of transmission oil. No warning lamps or messages appeared. This failure resulted in an extraordinarily expensive repair, over $2,500.00 at the dealer, Lexus of Greenwood Village (Colorado). It was not covered on warranty. This is a major safety issue - had I not noticed the leak, which occurred without warning, the engine could have seized on a highway, leading to a crash. This failed seal should be designed to last far longer than 90,000 miles. Premature failure of this kind is highly likely secondary to a defect in design or materials. I have complained to Lexus, which is unwilling to take any responsibility for this. Please investigate as to whether a recall is warranted, and whether the manufacturer should be responsible for the repair of this obvious defect. Thanks.

Lexus Nx300h 2016
- Date Of Incident: 2023-07-01
- Date Complaint: 2023-07-01
- VIN: JTJYWRBZ7G2
- Components: FUEL/PROPULSION SYSTEM
- Summary: While driving down the Interstate 75 at 70 mph the car completely lost engine power and the whole dashboard lit up. It would not respond to acceleration. I had to pull the car over to the side of the road. I re-started the car and it started back up and worked normally. The following day while on I-75 the car experienced reduced power this time. The car would not accelerate above 20 mph . We got off at the next exit. We spent about 10 minutes searching for the closest Lexus dealer and then when we went to start the car again it ran normally. This has subsequently happened a 3rd time where the car would not respond to the accelerator and I had to pull over to the shoulder and re-start the car. Unfortunately there are no error codes showing when we took it to the dealership on both occasions so they are unable to diagnose the issue.

- Date Complaint: 2023-06-19
- VIN: JTJYARBZ8G2
- Components: SERVICE BRAKES
- Summary: My brakes have stopped working twice. Each time I'll stop driving for a day and it's normal again. When it happens my brakes feel very loose and I can't control the direction of my car. I have to pump multiple times and/or press all the way to the floor to even begin to feel it begin to brake. I've had my car checked out and nothing was physically wrong with it.
Lexus Nx300h 2018
- Date Of Incident: 2023-02-10
- Date Complaint: 2023-03-28
- VIN: JTJYARBZ8J2
- Components: SERVICE BRAKES,FORWARD COLLISION AVOIDANCE
- Summary: After 45 minutes in stop-and-go traffic the brake pedal went to the floor four times, the Brake Override System (BOS) failed, throwing the shifter into Park failed, and we hit the car in front of us. No warning sounds typical for this car sounded and no lights appeared on the dash. Thankfully, we were only moving at 5 mph which I didn't think qualified as a "crash" but there was indeed a collision. No one was hurt. Besides my wife and myself there were two backseat passengers who also saw my efforts to stop the car. We had the car towed to Lexus of Santa Monica. Unsurprisingly, Ronald Inton with Toyota Motor North America, Inc. (TMNA) indicated in his letter to us that Lexus inspectors seeing our crumpled front license plate and knowing of the failure of the BOS found nothing wrong with the car, but had not driven it under stop-and-go conditions for 45 minutes as we had. The clear failure of the BOS to prevent the collision or even warn of the impending collision was effectively ignored my Mr. Inton. Our full correspondence with him is attached. Both my wife and I loved driving this car but it is a potentially deadly safety hazard and given that TMNA can't fix it, should be destroyed.

Great car! Although, I found the technology a bit confusing at times. Additionally, I was unsure why I had to pay for some of the features, such as the remote feature. It would be great if these were included at no extra cost.

My wife absolutely loves the car I got for her! As someone who is 6'2'', I have to say that this is the most comfortable car I have ever ridden in. I really enjoy being a passenger in it. The only things that could make it better are more storage space and a touch screen for the navigation and radio systems.

So far, I am thoroughly impressed! Before considering this car, I had flirted with a Mercedes C300 and was left disappointed. However, the NX 300h has exceeded my expectations with its spacious interior and great gas mileage. It is also stylish and smooth. I even took it on a cross-country road trip with 4 adults and it easily accommodated us all.

Your Lexus NX 300h has a fantastic interior design! I've owned mine for 4 months now, having ordered it in November and received it in March. My friends who own non-Lexus brands have all complimented it, with two people even saying that the driver cabin feels like a cockpit. Even my 7-year-old niece loves it and always asks me to choose the 'SPORT' drive mode when she rides with me. The difference is huge - the drive is so easy and comfortable with great pick up. This is our first Lexus and first Hybrid, and my whole family is incredibly proud of it.

I recently started a weekly commute of over 200 miles, which includes going up and over a mountain pass. Unfortunately, I have been disappointed with the lack of power in my vehicle. I often find myself being passed by trucks unless I floor it, which results in unacceptable engine noise. The same goes for when I need to quickly merge onto the freeway. Additionally, I find the placement of the steering wheel to be too high and too far away, even when adjusted as far as it will go. On a positive note, my vehicle gets great gas mileage, averaging 31-32 mpg, and the climate control works well. However, I do have some concerns about the Lexus app suite, which controls navigation and entertainment. It could use some serious upgrades as it is incredibly inefficient and can be frustrating to use.

Unfortunately, the car does not come with wireless charging, power rear seats, or a head-up display. Additionally, I was disappointed to find that the dealer was unable to assist me, despite my willingness to pay for it.

I hope you're doing well! I just wanted to share some feedback on my recent ride. I noticed that I was feeling every little bump in the road and the interior felt a bit cramped. I've owned a couple of Prius' in the past and their interior felt more spacious. However, I must say that the exterior of the car looks really sharp!
Johnathan Reynolds 2024-07-28

Hey there! I hope you're doing well. I just wanted to share my experience with this car. Personally, I found it to be a bit pricey, especially since it's similar to the Toyota R4. Additionally, I noticed that the market value dropped by almost 30% in just 6 months, which wasn't ideal. On top of that, it tends to use quite a bit of gas and doesn't handle as well on the road. All things considered, I wouldn't necessarily recommend it to others. Thanks for listening!

I recently purchased my second Lexus NX 300 H 2019, but unfortunately, it turned out to be defective, just like the first one. The major issue is that the dinging sound comes on when you open the door, even when the engine is off. This is a safety concern as it could lead to accidentally leaving the car on. Despite having the same problem twice, I am hopeful that Lexus will address this issue soon. On a side note, I have owned several Lexus models in the past, including the RX 300, RX 330, and LX 470, but the NX 300 H has been the least satisfactory. It is quite noisy and has limited cargo space. Additionally, the windshield wipers are not adjustable and spray all over the car. The hybrid model also did not provide the expected fuel efficiency. Overall, I would not recommend this model until the issues are resolved.
