What owners report

Owners of the 2008 Lexus IS most often complain about a sticky, melting dashboard and door-panel material that turns shiny in sunlight and throws glare onto the windshield, and about an illuminated airbag/SRS warning light traced to the passenger-side wiring harness. Engine complaints also appear in the sample, including misfires, coolant leaks from the valley plate on IS F models, and oil consumption, generally at higher mileage than the interior trim complaints.

  1. Body and structure

    Sticky, melting dashboard and door panels

    • 40 complaints (39%)
    • median 64,000 mi at 6.5 yrs old (18 state mileage)
    • 1 mention a crash, fire or injury
    • filed 2014–2024

    Complaints describe the dashboard surface becoming soft, shiny and sticky in heat, often with door-panel material near the handles doing the same and leaving residue on clothing or paper left on the dash. Owners commonly say the glossy surface reflects sunlight onto the windshield badly enough to hinder forward vision, and several report that a dealer or the manufacturer declined to replace it, citing warranty expiration or that only a bulletin had been issued. Some mention parking in sun-exposed areas such as southern states as the trigger. Reported from low mileage up to roughly 145,000 miles, with most appearing under about 75,000 miles and repeatedly linked to hot weather and sun exposure.

    What to check: Inspect the dash and door-panel trim on a warm day for tackiness, shine or residue, and ask whether any dashboard replacement or rework was previously requested or performed.

    2 excerpts from owner complaints in NHTSA records

    “The dashboard IS melting and the door side panels pieces are falling off as if the plastic IS old and dry. I contacted Lexus who told me that the florida sun was too hot for the cars and that they were not at fault for this and also advised me that they would not cover the defects. Damage IS estimated at $ 1,200.00 per the dealer”

    NHTSA complaint #10617220, filed 2014-07, 50,000 miles

    “Dashboard melting, sun reflects on dashboard and reflects on windshield causing very poor visibility, called Lexus and they said they would supply me with replacement but that was 3 years ago I call every 6 months with the same response, even offered to pay but they claim they don't have supply”

    NHTSA complaint #10978994, filed 2017-04, 65,000 miles
  2. Engine

    Misfires, shuddering and rough running

    • 12 complaints (12%)
    • median 89,000 mi at 10.3 yrs old (10 state mileage)
    • 1 mention a crash, fire or injury
    • filed 2009–2024

    Complaints describe shuddering at stop lights, rough idle, stalling or losing power, and the check-engine and VSC lights coming on, with dealers diagnosing misfires or carbon buildup. Several owners mention engine work done under an extended warranty for carbon deposits or pistons and rings, and some say the misfire returned after the repair. Spread from about 15,000 to 150,000 miles, with many reports in the 60,000-110,000 mile range.

    2 related service bulletins

    What to check: Ask for service records covering ignition, fuel-system and carbon-cleaning work, and check whether the engine light or VSC light is on during a test drive.

    2 excerpts from owner complaints in NHTSA records

    “Ever since I had this car, I always had the constant problem of a weird engine smell of rotten eggs, it overheats out of nowhere constantly after multiple repairs and maintenance paid out of pocket. It would shut off while driving anywhere. These are just some of the receipts.”

    NHTSA complaint #11323801, filed 2020-05, 150,000 miles

    “I took my car to the local dealer for the carbon buildup recall in the motor. They rebuilt parts of the internal motor. After they rebuilt the motor for carbon build up, my engine light started to light up for bad catalytic converter. I told them that the light never showed up before and could've went bad from all of the miles of carbon build up that damaged the catalytic converter. They couldn't repair the catalytic converter because I was out of the warranty period.”

    NHTSA complaint #11051082, filed 2017-11, 104,000 miles
  3. Air bags

    Airbag/SRS warning light from wiring harness

    • 8 complaints (8%)
    • median 107,500 mi at 8.7 yrs old (6 state mileage, few)
    • 1 mention a crash, fire or injury
    • filed 2014–2021

    Owners report the airbag or SRS warning light staying on, which dealers have traced to the front passenger airbag wiring harness becoming loose or disconnected and leaving part of the airbag system inoperative. Complaints describe repair estimates in the low thousands of dollars and say the work was not covered outside warranty; some reference a Lexus customer support program or recall notice about the harness. Mostly reported between about 60,000 and 130,000 miles.

    2 related service bulletins

    What to check: Confirm the airbag light comes on briefly and then goes out at start-up, and ask whether the passenger airbag harness or any Takata-related campaign work has been completed.

    2 excerpts from owner complaints in NHTSA records

    “Got a airbag light on when I started my car this morning. Everything IS intact. Was reading forums about it. Says this problem IS very common. Please let me know I did not take a picture. But if needed I can take a picture and send it to you.”

    NHTSA complaint #11396356, filed 2021-02, 62,846 miles

    “The wiring harness for the front passenger airbag was recalled by lexus because it is too short and frequently becomes disconnected which disables the front passenger airbag and cause the air bag light to turn on on the instrument panel. Lexus sent a letter informing me of the recall, but it was sent to my parents house and I did not receive it in time. After finding the recall letter, the pandemic also prevented me from making it to the dealership in time. …”

    NHTSA complaint #11420881, filed 2021-06
  4. Engine

    Coolant leak at the valley plate (IS F)

    • 6 complaints (6%)
    • median 100,021 mi at 12.5 yrs old (5 state mileage, few)
    • filed 2020

    Owners of the IS F describe pink coolant dripping or pooling under the engine from the valley plate seal, sometimes with overheating or a sweet smell, and say the repair is expensive because of the labor involved. Some complaints also mention a cracked exhaust manifold on the same engine, noticed as a noise on startup or an exhaust odor. Typically reported above roughly 85,000 miles, often past 100,000 miles.

    What to check: On IS F examples, look for dried pink coolant residue around the top of the engine and under the car, and ask whether the valley plate seal or exhaust manifold has been replaced.

    2 excerpts from owner complaints in NHTSA records

    “My Lexus isf has a cracked passenger side manifold which IS very audible on startup and beginning signs of a valley plate coolant leak, which will eventuallylead to engine failure. These cars were made in very low numbers, however our car enthusiast community IS experiencing these failures in a higher than acceptable numbers of this rare vehicle. …”

    NHTSA complaint #11320597, filed 2020-04, 110,200 miles

    “It IS known as the valley plate leak. And it's radiator fluid leaking out which causes damage to the compression and also causes the vehicle to over heat easily. It happened when I let the car sit and started it and I noticed the valley plate started leaking.”

    NHTSA complaint #11320463, filed 2020-04, 100,021 miles

Buying note. Check the interior trim and dashboard carefully in sunlight, confirm the airbag warning light behaves normally at start-up, and ask for service history on engine work; on IS F examples, inspect for coolant residue at the top of the engine. Many of these complaints concern items owners had to pay for themselves, so documented repairs are worth more than assurances.

Summary written with AI from a sample of 60 NHTSA complaints for this model year (picked at random, with complaints that state a mileage and recent ones taken first), then checked automatically against the source records.

Example complaints

Other or unknown: “My issue pertains to the sticky dash and the same materials used on parts of the door near the handles. When the temperature gets over 80 degrees the material starts to melt and becomes extreme hot and sticky. When I tried to grab papers I left on the dash I had to tear them off and it left a sticky substance. It also can become extremely hot and when I hit any part of the dash when heated it burns and sticks to me. I attempted to contact Lexus and they declined my claim because it IS not a 'safety issue to them or the NHTSA'”

NHTSA complaint #11403928, filed 2021-03, 102,120 miles

Engine: “In august 2012 my car's engine light and vsc light came on. I took the car to the dealer and they found multiple misfires. The dealer replaced the gasket and 3 pistons and ring sets under warranty. My car engine has continued to intermittently shudder when moving and when idling at stop lights. Today (1/3/17) I was driving on the highway at normal speed and once again my engine light and vsc light are lit up. I received the 9 year extended warranty for carbon buildup, but it only covers me through 3/8/17. If I have carbon buildup again after that, it will cost me $2,000-$3,000 to fix. …”

NHTSA complaint #10939530, filed 2017-01, 104,000 miles

Body and structure: “The dash board starting getting worse day by day getting extremely sticky and starting to have melt spots causing a huge glare when I'm driving. I know this IS a big problem on a lot of Lexus IS owner 06-12. I use the wind shield visor all the time and never wipe with chemical.”

NHTSA complaint #10626147, filed 2014-08, 58,000 miles

Air bags: “Takata recall I am in zone b and my car IS approaching its ten year mark. I took my car in today and asked the sales assistant if there were any updates about the airbag recall and he told me, no . What IS supposed to save me in an accident can now kill me. I am very disappointed in the amount of time this has taken and the response to consumer concern. Please put pressure on toyota and takata to fix our airbags.”
