Tidbits of Cute Information about the Lexus GX470The Lexus GX470's competitors include the BMW X5, Cadillac SRX, Hummer H3, Land Rover LR3, Lincoln Aviator, Mercedes-Benz M-Class, Porsche Cayenne, Saab 9-7X, Volkswagen Touareg, and Volvo XC90. It also competes with luxury brands as Europe's Audi and Jaguar, the American Cadillac, and Japanese peers Acura and Infiniti.To call the Lexus GX470 a truck-based sport utility vehicle is a little misleading because the ride one experiences inside it is quiet and smooth. But a truck-based SUV it is, so if one wants to blaze trails in the $46,000 rig, the GX will be happy to oblige.The GX basically is a Toyota 4Runner dressed to the nines, similar to the Lexus' other midsize sport utility, the RX330, which is a bit smaller and is based on the Camry sedan. It is meant to combine a high-quality interior with high-mountain adventure. However, the GX470 was originally based on the Toyota Land Cruiser Prado (J120). The two vehicles shared a common platform, mechanicals, and bodyworks; therefore they have common basic dimensions. Likewise, the interiors were much the same, with the Lexus receiving further premium touches. Even the GX470's production occurred at the same place as the Prado's-at the Tahara plant in Japan. One can say that Lexus GX470 parts and Lexus GX470 accessories are similar to the Prado's. The GX470 essentially lived on as the redesigned Lexus GX460.Hunter Communications, the agency that designed the "L" logo of the Lexus GX470 and also presented the name to Toyota executives and managers, said Lexus came from the "LE" on the automaker's luxury edition vehicles, which created the acronym "Luxury Edition for the United States" or "LEUS" with the "x" from luxury added to form "LEXUS".The Lexus GX470 has won various awards including "Four Wheeler of the Year" in 2003 and 2004 from Four Wheeler magazine. J.D. Power and Associates named the GX470 the highest-ranked premium luxury SUV in 2005, and Kelley Blue Book gave the GX470 its Best Resale Value Award in 2006.The Lexus GX470 has not been crash tested by the federal government or the Insurance Institute for Highway Safety but it offers an array of standard and optional safety features such as driver and passenger airbags; four-wheel disc brakes; electronic stability control; child safety locks; emergency trunk release; four-wheel antilock braking system; brake assist; daytime running lights; and traction control.
Lexus GX470 Common Problems
Lexus boasts of quality Lexus GX470 parts and Lexus GX470 accessories, plus an adequate passenger and cargo room. However, the Lexus GX470 is not perfect. Here are some of its reported imperfections.
The number one most common problem in this area is related to the vehicle's driveshaft, with drivers complaining of a thumping sound that comes from there while driving and accelerating. Lexus is aware of the problem and states many of the GX470s have it. However, service techs acknowledged that replacing the driveshaft doesn't resolve the problem.
Drivers have also complained of rotor problems. After only 15,000 miles excessive wear out of both front and rear brake pads and rotors was reported. The safety concern is the sensation of movement of the car-this is startling and could potentially cause a driver to remove his foot from the brake, possibly leading to an accident.
The transmission design is defective; the vehicle lunges and thrusts forward while the brake is firmly engaged as a result of the defect. The rear driveshaft allows the full weight of the vehicle to slide forward causing a loud thump and propel the vehicle in a forward motion several inches despite having the brake engaged.
Power train problems
Drivers complain of a thumping noise when releasing the brake pedal-a sound that feels like someone is tapping at the rear of the vehicle. Also complained about was a hard accelerating sulfur smell entering the cabin, unintended acceleration of the Lexus GX470 when shifting from park to drive, and jerking when shifting at low speeds.
Vehicle speed control problems
There have been complaints of the Lexus GX470 suddenly accelerating even when car owners had no intention of the vehicle doing that. Calls of an investigation of all Lexus GX vehicle speed control systems to determine if they develop flaws over time or if there's an issue inherent with the system that causes the uncontrolled skids were made.
General issues drivers experienced were air conditioner condenser leaks; ride height sensors going bad; vibration through the steering wheel and gas pedal; and the DVD player making a high-pitched noise when not in use, especially when idling.
My engine suddenly had a difficulty starting up. What could probably go wrong with my engine? Please help me with this.
Have you checked your fuel gauge? You might be lacking fuel already that's why you find it hard to start your engine. Or if you have enough fuel, an air intake that is clogged can also be the reason for this problem. Make sure that there is no impurity and contamination in your fuel that makes it harder to burn. Lack of compression caused by air and fuel that are not compressed properly can also cause this problem. There might be a leak in the cylinder, or the intake and exhaust valves are not sealing properly. Check your piston rings if they are already worn. A worn-out piston will allow air and fuel to leak during the compression. Test your spark plugs and wires if they are weak. The fuel will not burn on a perfect timing if the spark happens in advance or delay. Also, make sure that your battery is charged.
I can hear a thump from my Lexus GX470's tires. Do I have to replace my tires already?
Your tire might be out of balance and will cause annoying sounds and vibration during high speed. Make sure that your tires are in proper alignment as well. It is not necessary to replace your tires just because you hear a thump. Spend time analyzing your wheels, so you will be able to point out the problem. If you notice that your wheels have bulges and bubbles, consider replacing them immediately because they will definitely blow up your tires.
I don't know why, but there's a transmission delay after my car has been idle for few a minutes. Is it normal?
Having a hard time shifting from one gear to another is not normal but still a common problem. Your car should shift to another gear immediately when engaged. Low transmission fluid can cause shifting delays and jerking, so you have to check it on a regular basis. Delayed engagement can happen anytime, especially when the temperature is extremely high. Do not rev up your engine during the delay, because it will just damage the clutch and bands. Again, do a regular check up on your transmission fluid level, and make sure to use the correct fluid type for your Lexus GX470. You may consult a professional if you cannot identify which type of fluid will work best for your car.
The air compressor of my Lexus GX470 produces annoying noise. What are the possible causes and solutions for this?
One reason can be from loose ends of some parts of the system just like the pulley, belt, belt guard, flywheel, clamps, cooler, and some other accessories, so make sure to tighten them all. Also, you might be lacking oil in the crankcase, so check and top it up regularly. If the crankcase is worn out, replace it immediately. The noise can also come from a piston that is hitting the valve plate. Check if there is foreign debris and make the necessary cleaning. If your compressor floor mounting is loose, you have to tighten the bolts and consider replacing your vibration pads.
Lexus GX470: A Midsize Luxury SUV with Superior Off-Road Capabilities
The Lexus GX470 had the Lexus tradition written all over it. It provided the luxury for travel in a sport-utility vehicle that’s quiet and comfortable, thanks to its polished interior, smooth V8 engine, and three-row seating for better flexibility. Though adorned with luxury in its design, this mid-size SUV was very much capable of conquering the off-roads. Its features even earned it a number of awards during its stint. In 2003 and 2004, it was named Four Wheeler of the Year by Four Wheeler Magazine. It also made the Automobile Magazine All-Star list for 2003 in the mid-size SUV category and got the highest ranking in terms of initial quality for premium luxury SUV in 2005 by J.D. Power and Associates. In 2006, it got the Kelley Blue Book Best Resale Value Award. But even though the Lexus GX470 was a top-rated luxury SUV, it had its own disadvantages, especially in light of a faster-growing crossover SUV market at that time. It had an impressive towing and off-roading capabilities, but some related features made it heavier, a bit cramped, and less energy-efficient compared to other luxury SUVs.
2003-2009: The changes in the Lexus GX470
The GX470 was initially unveiled at the North American International Auto Show in the early part of 2002. It was launched as a 2003 model, making it the third SUV to be part of the Lexus family. The GX development plan began as early as 1999. The GX shared some common features with the Toyota Land Cruiser Prado. These vehicles had the same platform, body work, mechanical features, and basic dimensions. They both had a welded steel body-on-frame and an electronically controlled five-speed automatic transmission. They also came equipped with a four-wheel-drive system and center locking Torsen differential. When it comes to suspension, the layout of the GX was similar to that of Toyota 4Runner. The earlier GX was powered by a 4.7L 32-valve, four-ca, 2UZ-FE V8 engine that could generate up to 235 hp at 4,800 rpm and as much as 320 lb.-ft. of torque at 3,400 rpm.
For 2003, the towing capacity of the Lexus GX470 was rated at 5,000 lbs. The 2004 model came with an upgraded transmission. An optional Kinetic Dynamic Suspension also became part of its numerous changes, along with some safety upgrades such as the optional rear backup camera system and tire pressure monitoring system. The 2004 model had a better towing capacity of 6,500 lbs. In the 2005 model, the V8 power was upgraded to 270 hp. However, this power rate was dropped to 263 hp with changes in the testing procedure in 2006. The Sport trim became part of the lineup for the 2005 GX. Various options were also introduced, including voice commands for the climate control and Bluetooth compatibility. For the 2007 model, the navigation system underwent another upgrade, along with the use of a larger screen for rear-seat entertainment and the addition of an auxiliary audio jack. The 2008 GX also got a dark metallic grille, revamped turn signal lights, liquid graphite wheels, exterior and interior chrome, among other updates. The next-generation was introduced in 2009. This was later rebadged as the GX460, as the SUV now shifted to a 4.6L V8.
