LEXUS GX

VEHICLE SPEED CONTROL

When accelerating from stop the vehicle has a long hesitation or lag, but allows enough movement in the vehicle to push the vehicle into an intersection. The safety concern is when pulling out across traffic to make a turn the lack of acceleration leave the drive susceptible to being hit by crossing traffic. I contact the Lexus dealership maintenance department and they indicated that it's a know problem and there isn't a recall or a solution. There is no warning light not other mechanical problem. I would not submit this concern if I didn't feel that this is a life threatening concern. There is far to much hesitation in acceleration, compounded but the fact that there is just enough acceleration to put the care in harms way with out enough to avoid a potential accident.

UNKNOWN OR OTHER

I was just getting off from work starting the engine, the driving meters screen and the head up display were completely off black, I thought that it will turn on after driving but it didn’t. I was driving more than 5 minutes on the free way and both screens were still dark. This is not the first time that this happened. The last time when this was happened, I brought my vehicle to the dealership where I purchased it, but then everything went back normal when I got to the dealership parking lot. They never performed any diagnostic or checking anything. Also the navigation/multi media scene flashing quite a bit. This car electrical system didn’t function properly and correctly when driving and could cause serious accidents or deaths, depending on who was driving. I really don’t know what more failure after this. In the past, Lexus had history of vehicle brake failures and couldn’t stop that claimed someone lives. This issues should be addressed before something else happens. ( I also have video available to support this concern)

POWER TRAIN

On July 19th, with less than 100 miles on the odometer, the vehicle began down and upshifting so hard that it felt like a collision. Additionally, when attempting to accelerate, the transmission would hunt for gears without engaging, resulting in loss of power - creating a very dangerous situation. Lexus is unable to identify a resolution and has had the vehicle in the shop for 2+ weeks

ELECTRICAL SYSTEM

System Failure: This vehicle has a narrow shelf molded into the dashboard above the glove box. There was a small container of hair lotion stored there that melted in the heat and dripped through the dash and destroyed the electronic control unit or ECU (#89221-60630 Multiplex Computer) and the power distribution assembly (#82730-60260 Power Distributor Assembly). This damage completely disabled the vehicle. Apparently, the ECU (a) is located where fluid can reach it through the dash and (b) it does not have any kind of shielding to protect it from being damaged in this way. Safety Issue: I am extremely lucky that I was not in a remote location when a few drops of hand lotion rendered my vehicle 100% inoperable. No prior warning: There was no warning prior to a complete failure of the vehicle to operate. Inspected by manufacturer: The vehicle was inspected at a Lexus dealership and remains there.

SERVICE BRAKES

At approximately 6,000 miles we drove this vehicle from Chattanooga to Nashville and back. The interstate has one steep grade. On the decent home the vehicle was violently shaking. It felt as if the car might not be able to stop or something had been broken. We had 30-45 minutes of driving to get home and considering having the vehicle towed. It continued to shake, less violently as we braked on the way home. It was terrifying. I took the car to Lexus and they told me that this can happen on steep grades. They wanted to turn the rotors and I insisted they be replaced due to being defective and causing this shaking at such low miles. They agreed. A month later, after having brand new rotors and pads, the same thing happened again. Again I immediately made an appointment and the vehicle was inspected. They told me this time there are hot spots all over these new rotors, from this one trip to Nashville. They told me there was nothing else they could do. I opened a case with Lexus corporate and they just reached out. They spoke to the dealership and concluded that this happened because of normal driving conditions. They are saying this is normal! It’s not normal. I explained the many brands of vehicles we have had and driven this same interstate many times without issue. This is unsafe. People that drive in mountain areas should not need brake repair every few thousand miles. And what if someone is driving in a very mountain area like the Rockies and one trip across the state could completely destroy these brakes? So scary. They need brakes to handle higher heat to protect families using this car. I am shocked this is not recalled already. I pray there is something to be done to get this fixed immediately. The uploaded file below is from the second time I brought it for the same issue. It was 5 weeks later. The incident for the second incident was just 4 weeks after the first one, but we had to wait for them to get us an appointment.

AIR BAGS

The airbags didn’t deploy in a collision that included the front and rear. My head and body was smashed into the steering wheel and dash. There were no warning that there may be a problem with this system. We have not had an inspection yet but are hiring an investigator for that purpose.

SERVICE BRAKES

Brakes squeal when backing up in the mornings and occasionally going forward. Maunufacturer is aware of the problem, but until recently would only allow dealers to order 1 repair kit per week. Now the manufacturer is allowing 4 kits per week to be ordered. This problem appears to affect 2/3s of all vehicles sold. Repair parts are taking 4 to 6 months to get. The manufacturer is not being responsive.
