My vehicle stalled at a red light and would not restart. After being towed to the dealer, they came back with a diagnosis of massive carbon build up. They advised that I reach out to Lexus corporate to determine if there was any support I could receive. After several weeks of going back and forth, Lexus corporate refused to provide any assistance because the car could not produce any of the necessary trouble codes to qualify for their customer support program surrounding this issue. After much hesitation, I agreed to pay $700 to have the top cleaning done. After top cleaning was complete, the dealer calls to report that the car still wouldn't start and they didn't know what was causing the issue. Now they have an "expert mechanic" from Lexus corporate coming out to inspect the vehicle and determine the problem. This took another 1 1/2 to 2 weeks to complete. I received a phone call from Lexus Corp, that the issue was now a timing chain that was going to be $1200 to replace. When I spoke with the dealer, they agreed to credit back my $700 from the misdiagnosis but quoted that the timing chain would be $1700, not $1200. After several days of haggling, I finally agreed to pay $1350, only to get another call from the dealer now saying that metal shavings have fallen down into the engine block and the entire engine would need to be replaced. Although I have all of my service records, Lexus Is trying to pin the blame on me, stating "lack of oil changes". my vehicle's year, model and date of service are all qualified to be covered under this warranty. This car has proven to experience these problems associated with this recall and because the engine Is in such bad shape and Is unable to produce any codes, they are refusing to honor this warranty. This has now been going on for nearly 3 months and I still have no car and no resolution in site.

The car like many push button start cars requires that you step on the brake pedal when starting, but the car will not start sometimes and/or requires a lot of force on the brake pedal to start the car which is apparently due to the brake booster going bad. This has been happening intermittently over the course of the year or about 9000 miles. I took the car to the Lexus dealer and told them what I thought was wrong because if you google "Lexus IS350 brake pedal hard" or "Lexus not starting" you will see that many people have this same exact problem with their Lexus, and not just with this Lexus model. The dealer confirmed the brake booster is the problem and that the cost to replace it would be approximately $1,100. After contacting Lexus customer support and pointing out that a lot of Lexus owners seem to have the same problem, they said it is not under recall, and that I must pay for the cost of the repair. I can see situations where a car not starting could be considered a safety issue, but more upsetting is that there is clearly a defect that many Lexus owners are experiencing, Lexus probably knows it, but will not correct it or recall it.

Vehicle randomly shakes, intermittently runs rough while braking. Dealer could not diagnose issue 3 times until recent check found engine pistons and valve springs need to be replaced. Lexus agreed to accommodate service and labor costs but parts are back ordered requiring a week or two wait time for repair.
