Fuel/propulsion system
3 reports
“[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.”
Steering

“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!!”

“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…”
