What kind of bad

The letter says how bad. This says what kind — whether this year drew an unusual number of complaints, unusually dangerous ones, or failures that arrived unusually early.

Complaint volume 50 vs 50 Severity 100 vs 50 Early failure 63 vs 50
The dashed ring is 50 — the national norm. Further out is worse.

28.8% of these complaints involved a crash, fire, injury or death, against a national rate of 9.7%.
Early failure — 63
37% of failures with a mileage on record happened under 36,000 miles, against a national rate of 29%.

Recalls on the 2010 Lexus IS

A complaint is one owner's allegation. A recall is the point at which the manufacturer or a regulator agreed the defect is real and dangerous enough to fix for free — however old the car is.

Canada — Transport Canada

Canada runs its own recall programme, and its campaigns do not always mirror the American ones.

Recall 2018346 4,915 units in Canada

Fuel System

On certain vehicles equipped with a 3.5L V6 engine, the fuel pulsation dampers located in the fuel delivery pipe could develop a leak over time. A fuel leak in the presence of an ignition source could increase the risk of fire causing injury and/or damage to property. Correction: Dealers will replace the fuel delivery pipe with an updated part.

Recalls cover specific build ranges, so check your own vehicle by VIN at nhtsa.gov/recalls or, in Canada, Transport Canada.

My vehicle's dashboard was melting. I thought it was some kind of condensation. When trying to wope it, sticky gook came off on my papertowel explosing the bottom level.of the dashboard. I went through all the levels all.the way to Corporate Lexus legal in TX as the fumes were making me sick. I am a senior citizens who was not planning on buying another vehicle as I drive very little. After 4 months with no help from Lexus having symptoms of anxiety, confusion, headache and extreme fatigue, I pushed myself to go drive to dealership which was s lot further than I was comfortable driving thr car in that condition. I told them I did not want another Toyota or Lexus so Itraded it in for a larger used vehicle than so I did not gave to drive the Lexus home. I was feeling even worse after the ride yhere and had developed a nagging little cough that does not go away. I also googled my symptoms which sound like Neuroinflammation that could be associated woth a melting dashboard. This has been a horrible experienced for me all around. I have plenty of documentation with Toyota/Lexus.

AIR BAGS

I had a head on collision with a light pole and the airbags did not deploy. The vehicle was inspected by aProgressive insurance claims adjuster and they claimed the vehicle a total loss. They kept the vehicle. There were no warning lights or anything. The vehicle had been taken into a North Park Lexus dealership after a defective airbag recall to be serviced in 2018.

UNKNOWN OR OTHER

My car experienced sudden unintended acceleration. I was at a stop light preparing to turn right when my car accelerated of its own accord crashing into the vehicle in front of me. My foot was firmly on the brake, but I had lost control over the vehicle. Whatever electrical defect I experienced, it was sufficient to rev the engine by itself and override the braking system enough that the vehicle advanced forward in an out-of-control manner. It was unintended, unexpected and beyond my ability to control. Failing to recognize the braking system, my vehicle collided into the vehicle a second time. Because my foot was on the brake and my vehicle still advanced forward, I initially thought I had been hit from behind. However, the erratic RPM behavior and the vehicle's continued acceleration while braking confirmed I was no longer in control of the vehicle. Acting promptly, I immediately took the gear shifter out of drive and put into neutral. It was then and only then that I regained control of the vehicle: it stopped accelerating, stopped revving of its own accord and began responding to the braking system. Please note: my foot was not on the gas pedal, for as soon as I took it out of drive, the RPM returned to normal (i.e. the erratic behavior indicated by the tachometer's RPM, stopped). Had my foot been on the gas pedal instead of the brake pedal, the revving would have continued to behave as before; but it did not. (I do not have an all-weather floor mat. It is neither here nor there, because in the event that I did have one, you would expect the RPM behavior to continue when put into neutral; but again, all behavior returned to normal when the vehicle was put in neutral.) Though I am sympathetic to those that panic in a moment of distress, I was of a present enough mind to know what was happening. An electrical engineer with intimate knowledge of the computer system for this vehicle would be the best to assess what went wrong from a technical perspective.

Developed a fuel leak at the tank that has previously been exactly described as a recall on the exact year make and model of this vehicle however, when entering my VIN it does not show my VIN number as being affected. I feel there has been a mistake on the Vin number range. However, Lexus refuses to handle the issue under the recall since the VIN number does not trigger as such.

UNKNOWN OR OTHER

Exterior driver's door mirror failure. The mirror is insecure, loose, unstable, not secured to the door, and rotates freely on its own. This condition makes it impossible and dangerous for the vehicle's driver to observe any vehicle approaching from the rear, left of the driver's side. The mirror is not secured to the vehicle's driver's door and spins freely. The driver cannot observe any approaching vehicles when pulling out from a parallel parking spot. This condition is this vehicle's "2nd" such incident. Previously, this identical situation happened to the mirror mounted on the passenger side door about 2 years earlier. The maintenance record is on file at the dealership. I paid the Chatham Lexus Dealership approximately $1000.00 to correct this.

Ewa Beach, HI

ENGINE

While driving home in the freeway, I felt my car shake then a sudden loss of power. Then my CEL started blinking and my VSC lit. Got a code for engine misfire(P0302). Is250 has a lot of cases on engine misfires because of excessive carbon build up because of how the engine is designed. My car only has 108,000miles. Lexus released a Customer Support Program for this problem but it already expired. They only gave 9 years from date of purchase for it to be eligible for the free fix. It means they are aware of the problem but my 2010 car just missed that window but I am having the same problem many IS250 owners have. It is really unsafe when you’re driving in the freeway then it suddenly loses power. Hopefully this problem gets resolved by Lexus soon.

SUSPENSION

Front suspension does not have adjustable Camber. The wheels have a negative Camber that is outside of Lexus specification. This causes a very large uneven wear inside of tire, which is not noticeable from the exterior of car. Owners will be unaware, when checking the tires, that the inside of tire is worn to a point that can cause the tire to burst. Car was sent to the dealer, and they confirm that the negative camber is present and there is no fix because camber can't be adjusted. There is no warning lights or symptoms prior to failure. Vehicle suspension is not modified with non-Toyota approved equipment.

FUEL/PROPULSION SYSTEM

THERE IS CURRENTLY A RECALL OF THE FUEL DELIVERY PIPE ON MY VEHICLE WHICH IS A 2010. I AM CURRENTLY IN FOR SERVICE AND THEY ARE TELLING ME THE FUEL PUMP ALSO NEEDS TO BE REPLACED AS IT IS LEAKING AS WELL. THEY ARE TELLING ME IT IS NOT UNDER RECALL AND IS ALMOST $2,4000. PER CONSUMER REPORT: TOYOTA AND LEXUS ARE RECALLING ABOUT 1.8 MILLION VEHICLES FROM THE 2013 THROUGH 2019 MODEL YEARS BECAUSE THEIR FUEL PUMP COULD STOP WORKING, WHICH COULD LEAD TO A SUDDEN STALL OR HESITATION WHILE DRIVING. THE PROBLEM INCREASES THE RISK OF A CRASH, ESPECIALLY WHEN THE VEHICLE IS TRAVELING AT A HIGH SPEED. SOME OF THESE VEHICLES ARE BEING ADDED TO AN EXISTING RECALL THAT WAS ALREADY ANNOUNCED IN JANUARY. I WOULD LIKE THIS LOOKED INTO FURTHER AS THERE IS A CORRELATION IN 2013-2019 MODELS.

ENGINE

ISFS YEAR MODELS 2008-2014 ARE AFFECTED THE VALLEY PLATE LEAK DUE TO THE FACT THAT TOYOTA/LEXUS UTILIZED THE IMPROPER SEALANT AND USED THE IMPROPER AMOUNT, LEADING TO THE HEAT EXCHANGER LEAKING COOLANT ONCE THE ORIGINAL, INADEQUATE SEALANT BEGINS TO DISINTEGRATE. THIS COULD CAUSE A CONDITION WHERE THE ENGINE COULD FAIL AND SOMEONE COULD GET HURT. FURTHERMORE, ALL ISFS WILL EVENTUALLY HAVE A CRACKED RH MANIFOLD ON THE #8 RUNNER. THIS CAN CAUSE A FIRE HAZARD IN ADDITION TO CARBON MONOXIDE POISONING.
