Common 2018 Lexus Nx300 problems
The 2018 Lexus NX 300 has been reported to have several common problems by its owners. One major issue is related to the engine, with some drivers experiencing rough idling and misfiring. This problem was initially attributed to contaminated gasoline, but the issue persisted even after flushing the tank. The engine problems resulted in the car running on three cylinders instead of four due to one cylinder head flooding. This issue caused the check engine light to come on, and the car also displayed alerts for AWD, parking brake, and traction control being disabled.
Another problem reported by owners is excessive wind noise, which is not typical for a luxury SUV. This issue can be particularly noticeable at high speeds and may be a sign of poor insulation or other problems with the vehicle's design.
In some cases, the windows of the 2018 Lexus NX 300 have been reported to not roll down properly, which can be a significant inconvenience for drivers. This issue may be related to the window regulator or other components of the window mechanism.
Additionally, some owners have reported problems with the rearview camera, which may freeze or become unresponsive. This issue can be particularly problematic in situations where drivers need to reverse or park in tight spaces.
While these problems are not necessarily widespread, they are essential to consider when looking into the Lexus NX years to avoid. By understanding the common issues reported by owners, prospective buyers can make informed decisions and know what to look out for when considering a 2018 Lexus NX 300.

I told Advisor about the recall and sent her the recall notice online. Advisor looked into the fuel pump recall in our telephone conversation, confirmed the fuel pump was recall n would be replaced. I told her i saw where the failing fuel pump with my Lexus online described what my vehicle was doing. Advisor now said car coolant fans/etc needed to be replace, I didn't understand this when I didn't have a cooling problem before coming there. Advisor tried to pressure me into the coolant fans/ module issues before doing my failing fuel pump, suddenly. I felt they were now lying about fans .

SERVICE BRAKES,FORWARD COLLISION AVOIDANCE PROBLEM
- Date Of Incident: 2023-02-10
- 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.
