 Toyota confirms safety problem with Lexus GX 460
2010 Lexus GX460

Toyota engineers have confirmed the serious safety-related issue with one of their company's vehicles.  Following a published account in Consumer Reports listing the 2010 Lexus GX 460 as a "do not buy" due to rollover risk, employees at Toyota successfully replicated the test conducted by the magazine.

“They duplicated Consumer Reports’ results on the GX 460 and they are currently evaluating potential remedies, but at this point there is [sic] no details of what the remedy is,” Lexus spokesman Bill Kwong told the New York Times.

Consumer Reports linked the potential rollover to a slow-responding electronic stability control, and noted that other SUVs allow the driver to regain control quicker.  The report led to Toyota ordering a sales freeze on the SUV until a solution to the problem could be found.

Vehicle testers for the magazine noted that in evasive or extreme driving situations the rear end of the vehicle would slide significantly, leading the model to be sideways before the stability system kicked in.  Kwong said that the company is "very concerned," and sees this as a serious issue.

Toyota has recalled millions of vehicles over the last six months for a variety of safety problems.  Amongst the most notorious is a sticking gas pedal that caused sudden, uncontrolled acceleration in several of their models.

Lexus hopes to discover the cause of the problem in the Lexus GX 460 within a week.

No. Because the toyota uses a V-6 as opposed to the Lexus' V-8, the Toyota is some 400lbs. lighter, and doesn't experience the same issue.

No Josh, Kerb weights of the vehicles are as close to being the same as it makes no difference. Lexus GX460 = 2,326 kg. Toyota Prado Kakadu (4.0 V6) = 2,340kg.

The automotive world should minimize the production of SUV's since a high center of gravity is obviously going to increase rolling over. Just compare the roll over ratings between SUVs and cars and you will see that no SUV has 5 stars rating for rolling over. There is only so much stability control can do. That excuse about carrying stuff is just lame since a stationwagon or van can carry just about the same. Going off road?...More than 95% of SUV's only travel on paved road. Everyone knows most people are just buying it just for the macho look...and there are so many of SUVs here in the US.

look at a BMW X5's ratings and safety reviews. Its is built to have a low center weight of gravity when compared to other SUV,s.

BavarianBS the X5 is also completely useless when it is taken anywhere that isn't covered in asphalt. The GX/Prado chassis is pretty close to being unbeatable and indestructable.

Most drivers are not taught how to handle emergencies in drivers education. There is only so much safety that can be programed in a car.

Hell, in the U.S. you don't even need to possess the ability to parallel park your car in order to get a licence. On the other hand I sure enjoyed not paying $1,000 in order to get mine.

Lower the centre of gravity? Widen the track? Use air suspension or stiffen the dampers or something to reduce body roll? Use wider tyres? Lower the ride hight a bit? It's not all that difficult.

They could widen the track of the car and refit a suspencion so the car could sit a bit lower, other then that and regarding the engennering of the car its all they can do, other then that re-program the electonics or just make a new one. Please while ure at it, could u make it a bit prettier???lol @ BavarianMS, that is also why the x5 is one of the worst suv's in its class, its great on the road, but off-road caugh caugh

The safety problem isn't a byproduct of the cog. It's an electronic defect where the stability control doesn't engage until the vehicle is sideways.

The laws of physics is Godhimself. Electronics cannot overcome physics. Having seen the car on the road I always thought that the track was too narrow for it's ride height. This car brngs shame to the Land Cruiser heritage. The stupid RX is enough SUV to have in the Lexus portfolio. Also makes one appreciate the PASM system in the Cayenne even more...love it or hate it what the Cayenne dos is impressive
