Lexus GX470 Engine problems by year

I have an 2006 lexus gx470 and these lights came on: abs, vsc trac, vsc off, skid, and check engine. The vehicle started making a humming noise at start up and now drives in stalled mode. Had codes check and it turns out I have the dreaded secondary air injection system (emissions) defect p0412, p0418 ,p1440/p1443, p1441/p1444, p2440, p2445, p1442/p1145 , which is a recurring problem. Replacement is a nightmare for self repair or a $2000+ repair.

Tl* the contact owns a 2006 lexus gx470. While driving approximately 35 mph and attempting to merge onto the highway, the vehicle did not accelerate past 50 mph. In addition, the check engine, vehicle stability control, and traction control warning indicators illuminated. The contact continued driving and stated that the failure occurred for approximately three weeks. The vehicle was taken to lexus of greenville (2660 laurens rd, greenville, sc 29607) where it was diagnosed that the secondary air pump and valve switch failed and needed replacement. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 168,000.

Secondary air injection system pump stuck off bank1 code p2445. This issue is a common problem for lexus gx-470. Lexus extended warranty for repairs. However, the number of complaints from people warrants a recall. This malfunction is manufacturer's fault. The cost to repair at the dealer is around $2,000.

Entire frame of the car is rusted to the point that almost nothing is holding the car together and we've been told it's not safe to drive. Has been maintained on regular basis and has always been parked in garage at night and on most weekdays. Car shouldn't be rusted out when cared for meticulously (documentation available).

"The secondary air injection system switching valve stuck open both one and two" I called dealer and total parts cost me $1,200 not include labor yet. That's ridiculous.

Unintended acceleration of a 2006 lexus gx470 when shifting from park to drive. This is the first known occurrence of this abnormal activity in the 6 months I have owned this vehicle. The engine rpms went from idle to wide open throttle for 2-3 seconds when I shifted the transmission into drive. Since my foot was on the brake I was able to keep the vehicle under control. The engine returned to normal idle on its own. Fortunately, I was in the middle of an empty parking lot and there were no damages and no...

My wife reported problem to different dealers and problem has not been resolved excessive odors smell like rear brake pads burned. Reported to different lexus without being fixed until now.

While accelerating the vehicle emitted a sulfur/rotten egg smell. *Nm the problem was due to the catalytic converter. *Sc *jb

When hard accelerating sulfur smell enters cabin makes me nauseated... Wonder if carbon monoxide is entering cabin also . When stopping or stopped drive shaft bumps hard like someone hitting back of vehicle. *Jb

My suv when ever going up or down a hill at any speed lets out a horrible smell. I took it to the dealer and they claimed it was bad gas, I let the tank run to empty and switched gas dealers...The problem got worse. My son cannot ride in the back seat because he feels like throwing up even during short rides.*Ak

Whenever giving the vehicle moderate to high acceleration, a rotten egg smell comes out of the air conditioner vents. The smell is so bad that it makes me dizzy. *Ak

Whenever giving the vehicle moderate to high acceleration, a rotten egg smell comes out of the air conditioner vents. The smell is so bad that it makes me dizzy and I feel like vomiting. I've been told by the lexus dealer that this is a "normal characteristic of the vehicle" because of the sulfur content in fuel. I have owned several different models of lexus vehicles in the past and never had this problem. *La
