Problems with the Tires

When buying a new car, very few people worry about the integrity of the tires. With this Lexus car, it’s something that many owners had to deal with, with some disastrous consequences.

One Edmunds review states, “I bought the LS 500 not completely understanding just how dangerous the technology package is. The design is so not user friendly. The tiny touchpad that is at gearshift level is extremely sensitive and not easy to navigate. I love the way the car drives, but this set up makes it NOT WORTH THE PURCHASE.  Also I should have gotten a voice command system w touchscreen at eye level. Looking down all the time is so Dangerous. Also my tire shredded literally at 3k miles. It took manufacture 6 months after that to recall all 4 tires. I was very scared to drive the car. When it happened I was going 80. The car swerved all over the highway. If there had been a car near me it most likely would have been fatal. The absolute most terrifying experience I have ever been through. The dealer did reimburse me. I feel they should have replaced all the sorry ass run-flats way sooner than they did. I drive all over us. Buying this Lexus 500 LS has this far been a horrible DANGEROUS mistake. I also own a 460 LS that I have 100k miles and still Love.”

More than 6,000 vehicles were involved in NHTSA CAMPAIGN NUMBER 19V134000, which says that the tire sidewall reinforcement layer might crack and separate while driving. If this occurs, the stability and handling of the car are put in jeopardy. These run-flat tires might be “new,” but many customers wish they would have stuck with the tried-and-true models that keep the car on the road. For now, this model can only provide owners with the ability to boast about owning a high-priced lemon.

Problems with the Transmission

The powertrain of any vehicle is necessary for a smooth-shifting experience, but the defects in this Lexus make the ride anything but enjoyable.

One customer stated on Cars.com, “3 weeks into owning it the transmission is super aggressive, jerks so hard passengers regularly ask ‘facing problems with your new car.’ Things get worse when the car rattles if you accelerate on turning. Lexus service states all 2018 are built like this. Luckily I still have my 2008 LS460. I am selling this one, as Lexus won’t own it and I am embarrassed to own it.”

Sadly, Lexus has chosen not to respond to the numerous transmission-related complaints. For now, there is radio silence regarding any defects, but no one needs confirmation from Lexus to know that the issues persist. This bucking bronco is sure to stand out on the road, but not for the right reasons.

Problems with the Fuel System

The fuel system supplies the gasoline to the engine so that the vehicle can move. When something fails on this system, owners can be left stranded on the side of the road.

A user from Club Lexus remarked “My gas door doesn’t stay full open it just kinda falls back close with no resistance or detent to keep it fully open? Coming from a 2015 RC350 I know it didn’t do that but the dealer told me it was normal for the LS500?”

Not surprisingly, there is a fuel-related recall. NHTSA Campaign Number 20V012000 illustrates that the low-pressure fuel pump on nearly 700,000 models might fail. If this happens, the car will stall and occupants will be in danger of an accident. Basically, if anyone that wants to “live in the new” better be prepared to be injured after the tires fall apart, the fuel system fails or the powertrain gives you whiplash.
