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.

BROUGHT TO THE DEALERSHIP BUT THEY SAID THAT I MIGHT HAVE HIT SOMETHING SINCE THERE WAS THIS THREAD LIKE DENT- (WHICH THEY SAID COULD HAVE HAPPEN DUE TO THE MIRROR POPPING OUT OF ITS CASE.)

This is my wife's car and she absolutely loves it. However, we traded in our 2016 Lincoln MKX 2.7 twin turbo for it. The Lincoln was incredibly fast and averaged 22 MPG, but we managed to put almost 100k trouble-free miles on it. In comparison, the Lexus gets around 30 MPG but lacks the same level of performance. The biggest downside is the lack of memory seats, which would have been a nice feature. Although I only drive the car twice a week to fuel and wash it, I still find this to be a minor inconvenience. Overall, it's a nice car and we're happy with it. While the infotainment system on the Lincoln was easier to use, we're still satisfied with the Lexus. In today's world, it's important to get the most out of every MPG, and the Lexus has delivered on that front. I just wanted to be honest about my experience.

I'm impressed so far! The H model is much quieter than the gas model, which was the deciding factor in my purchase. I do think there was a bit too much time spent on demonstrations of the options, though. A quick guide would be better.

This is my third hybrid and by far my favorite. It's very comfortable and has a great ride. I'm getting a combined 41.4 MPG. Since I've owned previous hybrids, I know how to drive one to extend the MPG. I'm still loving my NX 300h! No problems and great MPG!
-
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.

I hope you're doing well! I just wanted to share some feedback on my recent ride. I was wondering if there's any way to improve the ride quality, as I found myself feeling every little bump in the road. Additionally, I noticed that the interior felt a bit cramped compared to my previous Prius models. However, I must say that the exterior design looks absolutely sharp! Thank you for your time and consideration.
