I started my car in the morning and when I started the engine it was an instant extreme rough idle with the engine light and traction control light blinking on my dashboard and the engine cuts out on its own. I have my car at a Toyota dealership since it’s closer than the Lexus dealership and they have ran an extensive testing diagnostic on my car resulting in a valve stuck open and a valve spring fell out. I have kept up the regular maintenance on my car, like every 5,000 miles fully synthetic oil changes, premium gas, regularly checking for recalls, always checking my fluids, correct tires and tire pressure, and I have in no way misused my car since it’s the only car I have to drive. I found that Lexus had a recall on the GS 350 for the 2007 to 2011 years for the problem I’m currently dealing with. In 2012 Lexus did not make a GS 350 but 2013 they were offered again and I feel like they didn’t resolve the engine problem before putting out the new production, at least for the 2013 year. Now as my car sits I have to pay $9,200 to fix the problem and I don’t have that type of money. I would have to sell my house to pay for my car to get fixed. Luckily the car didn’t stop running while I had my family in the car. I don’t feel that I did anything wrong to make the internal engine have a valve issue. This car should still be running at 148,100 miles.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2013 Lexus Gs450h verdict →
