Brake and electrical issues among the top complaints received by the NHTSA from vehicle owners

Lexus sells a variety of hybrid models, but the 2018 Lexus NX300H is one of the few luxury hybrid crossover models. The newest lineup is said to have “more response,” but the automaker falls short with the manufacturing. Instead of creating a high-end model that people could be proud to drive, it created a faulty electrical system and malfunctioning brakes.

Problems with the Electrical System

Whether it’s a hybrid or traditional vehicle, the electrical system is vital to operating the model. With this Lexus, there are troubles that are downright glitchy and annoying.

One NHTSA complaint reads as follows, “The contact owns a 2018 Lexus NX300H. Within weeks of the contact owning the vehicle it stalled several times without warning. The dealer was unable to duplicate and diagnose the failure. The contact was awaiting a response from the manufacturer to determine a repair remedy.”

Not only does this statement prove that the NX300H doesn’t have “more response,” but it also proves that the company doesn’t care to respond either. Instead, they have left a good customer hanging, wondering when the car is going to break down yet again. Sadly, it’s not the only electrical system problem. In fact, of all of the manufacturer communications, the electrical system receives the most attention. Service Bulletin #L-TT-0265-19 is just one example of what’s going on with the automaker. This states that the GFCI breaker will trip without a legitimate reason. If owners wanted a sub-par hybrid model, they could have chosen any number of other brands but didn’t expect this from Lexus. Instead of having a “Relentless Pursuit of Perfection” the company turns out to be a dud.

Problems with the Brakes

When the car is acting up, it’s helpful to have a reliable set of service brakes to fall back on, but that seems to be a problem with this Lexus as well.

Just read this NHTSA review. “I was parked at a stop sign on a city street with my foot on the brakes. Next thing I knew I was hitting another vehicle. My brakes unintended accelerated and my brakes failed. I could not stop this car for 2 blocks, I tried to place it in Park, and also turn the car off. The car would not stop. I kept my foot on the brakes but it just accelerated. I reported it to Lexus and according to Lexus, and independent analysis would come out and inspect my vehicle. The vehicle sat on the Lexus car lot for a month and was inspected a month later. Lexus notified me informing me that my brakes showed no evidence of failing. Well, either I am lying or Lexus is lying, or there is an underlying problem with the brakes that Lexus was unable to detect and choose not to admit because of the millions of dollars a recall can cost. It’s in Lexus’s best interest to deny my claim and wait for multiple of their customers to lose their lives before the company admits that there is a problem. I had no injuries and car I hit received no injuries. I was just so emotionally distraught that I haven’t driven in 3 months.”

Not only did this customer find out how well Lexus chooses to respond, but a quick look through the service bulletins shows that the company hasn’t issued any information about possible defective brakes. So, where is this “more response” Lexus? At this point, it looks like the only thing the company is getting more of is richer, off other people’s money, because the automaker isn’t fixing or acknowledging how much of a dud this hybrid vehicle actually is.
