I am writing to file a complaint against Lexus Corporation regarding a significant safety issue with my vehicle. Despite NHTSA’s recall notice for defective engine valve springs installed in certain 2008 GS350 vehicles with a specified range of VIN numbers that includes my vehicle’s, Lexus still persevered my car is not applicable for the recall and refused to cover the necessary repair costs after identifying the root cause of my car’s engine failure to be a broken valve spring out of a total of 24, as was initially diagnosed by a local auto repair shop. Their negligence of timely contacting impacted vehicle’s owner and outright refusal to cover this critical recall repair cost is truly outrageous as my own life and public safety have been in danger during these years. My vehicle experienced a near-catastrophic sudden engine failure with violent shaking and stalling at around 7:30am on April 27 while traveling on Highway 101. Fortunately, I managed to exit the highway safely during the heavy traffic and pulled into a nearby parking lot. It was towed to a local auto repair shop for initial diagnosis and a few days later transported to the Stevens Creek Lexus repair facility as instructed by them. The National Highway Traffic Safety Administration (NHTSA) has issued a recall (document link: https://static.nhtsa.gov/odi/rcl/2010/RCMN-10V309-1264.pdf) encompassing the range of vehicles affected by the defective valve springs, which includes my vehicle. However, despite being within the recall range, Lexus Corporate still refused to cover the repair costs. I respectfully request your intervention in conducting a thorough investigation into this matter. It is crucial that Lexus Corporate be held accountable for their actions, and appropriate measures be taken to rectify this safety issue without delay. The safety of consumers must always be a top priority, and I trust that NHTSA will take decisive action to protect the public from further harm.

2008 GS350 - 129k miles - 1 owner Looking for input on whether/how to proceed as this is now a multi-year problem (2019- 2021). My 2008 Lexus GS350 had the following recalls (All fuel and engine related): NHTSA CAMPAIGN ID: 18V432000; NHTSA Campaign Number: 14V647000 NHTSA CAMPAIGN ID: 09V020000; NHTSA CAMPAIGN ID: 10V309000 Before the last fuel assembly recall work was out of warranty 2019, I started experiencing an extreme fuel odor after a decline AND each time car was started (noticeable only with windows down). No warning lights, system reported no issues. Independent mechanic found a leaking fuel injector (port on that side is "clean".) (Lexus dealerships found no issues). Replaced fuel injector, no change in fuel smell, strong as ever. Neither Lexus or Independent mechanic can determine what is wrong. Pandemic happened and I only drive the car once a week to the grocery store, strong fuel smell on startup still happens. (Haven't been on any incline/declines). 5/9/21, filled gas tank, started car, made 2 stops before heading home, "Check engine, Check VSC" and a myriad of lights came up on dash. (Total of 3 startups after filling tank, lights came on after 3rd start). Code comes up - P0430 - Catalyst System Efficiency Below Threshold Bank 2 All the fuel related symptoms & issues can't be a coincidence. 2 Fuel assembly recalls, fuel smell, leaking fuel injector, continued fuel smell, now catalytic converter issue even though car is barely used in the last year.

Exterior lighting

WHEN DRIVING AT LEAST 3 MIN THE FRONT HEAD LIGHTS GOES OUT.DONT MATTER HOW MANY TIMES YOU GET IT FIX
NEARLY CRASHED INTO THE BACK OF A LEXUS SEDAN SLOWING FOR FULL SPEED TOLL PAYMENT. EVEN THOUGH THE VEHICLE HAD DAYTIME DRIVING LIGHTS, THERE WAS NO INDICATION IN THE REAR OF THE VEHICLE. HEAVY RAIN WAS AFFECTING VISIBILITY AND THE LACK OF ANY REAR LIGHT INDICATIONS NEARLY LEAD TO A MULTIPLE VEHICLE CRASH. I BELIEVE THIS CONDITION EXISTS ON MOST VEHICLES WITH DAYTIME RUNNING LIGHTS AND MAY VERY WELL HAVE LED TO NUMEROUS FATAL ACCIDENTS. NO LIGHT ON THE READ OF A VEHICLE DURING POOR VISIBILITY CONDITIONS CAN NO DOUBT LEAD TO RE-END CRASHES. *TR

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
