Having an issue with my 2014 lexus is350 steering..the steering feels notchy and grabs when going around curves..it does it when returning wheel back to straight position..and wheel has to be pulled back into straight position or it will keep pulling ..thats when it catches and causes the jerk in the steering.. Usually when driving a car It'll somewhat straighten itself smoothly.. I have taken it to repair shops to have alignment/ brakes/rotors done and nothing has helped this what so ever. I've seen many forums about this same issue.. why hasn't this been addressed ..its obviously a huge issue that's been ignored.. this car isn't old enough or with 89k miles on it to be experiencing these types of issues.. thanks in advance for looking into this!!

Defect investigations
Desiccated Air Bag Inflator Rupture
From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited. The rapid burning can cause the inflator to rupture during deployment, potentially causing serious or even fatal injury to vehicle occupants. See 2016 Blomquist Report at all frontal inflators using propellant 2004 that do not contain a "desiccant" (a substance that traps and holds moisture) in US vehicles are under recall. These "non-desiccated" inflators either have been or are required to be replaced.In some cases, the remedy part for these recalled inflators was, or will be, an inflator using either propellant 2004 or 2004L that does contain a desiccant. None of these "desiccated" remedy parts (which were installed in older model year vehicles) are currently under recall for a degradation concern. Certain subsets of desiccated PSAN inflators using propellant 2004 for use as original equipment, however, have been recalled for a degradation concern. All Takata inflators produced with propellant 2004L contain desiccant, and none of these desiccated inflators using propellant 2004L are under recall for a degradation concern. There have been no reported field ruptures in any non-recalled desiccated PSAN inflators.It is understood that desiccants fully saturate at some threshold, at which point any additional moisture will not be captured. This means the degradation process observed in non-desiccated inflators using propellant 2004 may also occur in non-recalled desiccated inflators using propellant 2004, assuming additional moisture enters the inflator and high temperature cycling occurs. Based on available information, desiccant saturation can occur within the first five years in the worst environments, and the time required for full saturation is affected by multiple factors. While no present safety risk has been identified, further work is needed to evaluate the future risk of non-recalled desiccated inflators using propellant 2004.Three entities -- Takata (now known as TK Global), the Independent Testing Coalition, and Exponent -- have been studying the long-term behavior of Takata desiccated PSAN inflators using propellant 2004L (as well as 2004) in the presence of moisture and temperature cycling. The research efforts, which include development of predictive modeling techniques and field sample analysis, are ongoing. To date, none of the researchers have identified field evidence showing that propellant 2004L is undergoing a degradation process that leads to aggressive deployment and potential rupture. However, the time in service of such inflators remains short compared to that of the inflators using propellant 2004. Further study is needed to assess the long-term safety of desiccated inflators using propellant 2004L.The Office of Defects Investigation is opening this investigation to examine whether a safety defect related to propellant degradation exists in non-recalled desiccated PSAN frontal inflators manufactured by Takata. This investigation will require extensive information on Takata production processes and surveys of inflators in the field. Lists of recall actions that may have used desiccated PSAN inflators as remedy parts, as well as the makes and models originally manufactured with them, is available with the downloadable version of this document (see -- note this information is subject to change/revision as the investigation proceeds). This investigation does not supersede EA15-001, which remains open.

What 2014 Lexus IS 350 owners say
Most recent owner complaints, unedited.
2014 Lexus IS350 Destination Assist and Safety Connect stopped working. Lexus tech support has no clue on how to resolve this problem. They are telling customers to go to the dealership. This puts those in need of assistance or emergency that the SOS function of the vehicle to become nonresponsive. Including location of a accident or collision notification.
[XXX] Numerous times I've cleaned the area and it continues to build mold. A serious health and safety hazard. Foul odor from their vehicle smells like a fuel leak. Also car sputtering while driving. Vehicle check and no recall under my vin. INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).
The lexus dealer in puerto rico has not been able to solve the recall for the fuel pump. I have called the dealer several times at 787 273-3000 since oct 2020 and they state they do not have the parts available. I am concerned the car stops working while driving.
There is an urgent safety recall on my vehicle put out by you guys stating the fuel pump must be replaced or it can cause the car to seize at high rates of speed. I am military stationed in germany and the local german lexus dealerships are stating they have no access to this part because it is a us spec lexus. I have contacted lexus corporate to request they fed ex the part to lexus germany where I live to be replaced. They are slow rolling this and it has already been a month. It should not take this long. This is a serious recall. It's not a hard fix. They need to mail the part to my dealer here in stuttgart germany. With the high rates of speed driven here in german the liability for this is huge. The safety recall states that the car could fail at high rates of speed. And here in germany there are higher minimum speed limits. This should not require me to constantly email and call lexus back in the states for the part to be mailed here. This is an urgent recall yet lexus is not prioritizing my request whatsoever. I need help. Please.
When it's raining ,I turn on the wiper at slow speed it's working normal for about 2 min then it's will stop working . I have to switch it on high speed only. I almost got in to accident that day .it's happen more often now and then . I did brought the car to dealer they said can't duplicate the problem.
While driving in the rain my windshield wipers suddenly stopped working. The wipers 'froze' in the up position. I had to work the wiper control inside the car 6-10 times to get the wipers to work again. After a few minutes of driving the wipers stopped working again. The wipers only worked intermittently and only if I kept working the switch. I took the vehicle to the local lexus dealership and the vehicle was diagnosed as having "wiper relays shorting" causing the wipers not to work.
I purchased a 2014 lexus is 350 f sport from fort worth brothers, llc/alfa romeo fiat in fort worth, texas on july 20, 2018. I noticed the next day while driving the car at highway speeds that when applying the brakes, there is a "rumbling/grinding" noise and the car was hard to stop. I went back to the dealership the next day and told them. They checked the car and said they found nothing wrong and that they resurfaced the rotors. When I left the dealership, I continued to have the same problems with the brakes. I also told them that the car "shimmied/shaking" and "vibrated" very badly while driving and that the car needed new tires. They told me they had put new tires on the car, when, in fact, they had not. I continue to have problems with the car riding with a "shimmy/shaking" feel while cruising at 30-40 miles per hour. I finally took the car to sewell lexus on august 1, 2018. Sewell diagnosed the brakes and said the rotors were "warped" and alfa romeo fiat had put aftermarket brakes pads on the car. Sewell lexus resurfaced the rotors and the grinding noise is better, but still not 100% because of the aftermarket brakes paids on the car. I paid $190 out of my pocket to have the rotors resurfaced after having only purchased the car 2 weeks prior. I asked alfa romeo for reimbursement and they refused. They also refuse to put the correct brake pads on the car and they refuse to replace the tires. I reside in fort worth, texas but work in arlington, texas, so I drive 20 miles to work one way everudau. I have made numerous, repeated requests to alfa romeo to have these problems corrected, but they refuse. I should not have to pay money out of my pocket for these items especially since I just purchased the car on july 20, 2018.
While driving on a major highway, I needed the brakes to be applied very rapidly as a vehicle cut me off and immediately slammed on their brakes. Upon my full and rapid pressing of the brake pedal, the emergency brake force distribution system braking did not appear to apply as on previously vehicles I've had or have including two large SUV's. Brake pedal was applied and pressed with full and complete force to the point that it no longer went any further. Continued in motion, no sliding, minimal ABS kicked in. And accident did occur as vehicle did not stop in time. Prior to and since then, I've paid more attention to the peddle pressure and level and sure enough, unless I prepump the peddle, the peddle must be pressed beyond what is considered standard. If I prepump the peddle, then drive, the braking is ultra sensitive. I urgently need an investigation into what is going on as I am prepared to sell the vehicle but would like to have a professional review, test, examine whatever is necessary to determine cause of such a brake pressure failure. It is repeatable, but need to know who to contact. What can be done immediately?
Tl* the contact owns a 2014 lexus is 350. On several occasions, while driving, the contact noticed a sulfur odor in the vehicle. There were no warning indicators illuminated. The vehicle was taken to hennessy lexus of atlanta (5955 peachtree industrial blvd, atlanta, ga 30341 (770) 457-6800) where it was diagnosed that the fuel needed to be changed. The vehicle was repaired; however, the failure recurred. The vehicle was then taken back to hennessy lexus of atlanta where the dealer stated that screws were missing by the exhaust and a small amount of sulfur was noticed in the vehicle. The contact was advised that the odor was normal. While driving, the accelerator pedal was depressed to increase the speed and the sulfur odor became stronger. As a result, the contact became ill and had to pull the vehicle over to vomit. The vehicle was then taken to hennessy lexus of gwinnett (3383 satellite blvd, duluth, ga 30096 (770) 680-1000) where it was also diagnosed that the fuel needed to be changed. The vehicle was not repaired. The manufacturer was notified of the failures and stated that the issue was a fuel change. The contact was then advised to get a second opinion. The approximate failure mileage was 58,000.
