Lexus IS Maintenance and Repair



  • wendymwwendymw Posts: 2
    Well, I'm having buyer's remorse. Test drove the usual-- Audi, Infiniti,Acura, etc. I loved the fit and finish of the IS250. I also liked having AWD since I'm in the Boston area. Here's my problems:

    1) it is incredibly LOUD. I brought it back to the dealer, thinking something was wrong. There is so much road noise, I can't turn the radio up high enough to drown it out. I didn't notice this noise on the test drive. I wonder if my car has different tires than the tester. The sales guy drove with me in my new car and said the noise was normal.

    2) the Bluetooth stinks. People can't hear me even when I'm shouting. I have the volume turned all the way up-- but I just hear the other people really loudly now. They don't hear me any better.

    3) the Nav system is bad. It won't give you the actual turn by turn directions more then 3-4 steps ahead. I like to see the route it is taking me, to make sure I "agree" with it. It won't let me do this. It also doesn't have enough info (or I can't figure out how to get the info). For example, in the city, there are 3 different "100 Cambridge St" addresses-- each in a different zip code. It lists all three-- but doesn't list the zip code! So, I don't know which address it is taking me to. Same thing with POI. It lists "AMC movie theatre" about 8 times-- but doesn't tell me which AMC it is. Doesn't give the street names verbally either. It's a waste. I plugged my $150 garmin into the car since it's more reliable.

    So, the $2000 Nav is a waste. I got it mostly because you have to in order to get bluetooth. But both really stink in this car.

    4) Acceleration is nothing close to my former BMW 325i. I loved the Infiniti's pickup, but the car seemed a little too big, a little TOO zippy, and not as "polished" as the Lexus. I now wish I got the Infiniti.

    Any ideas about the road noise and lousy bluetooth?

    I would take the service manager for a drive, not the salesman.

    Also,do they have a similar car in their loaner fleet that you can compare yours to?
  • My rims came right off. Try hitting the lug area with a rubber mallet. Alternately, gently nudge the edge of the rim with your shoulder, but be careful not to nick the studs.
  • The road noise is noticeable on the IS. Tire and rim selection and the stiff suspension are key components to the road noise issue. When I switched from the factory Dunlops to Michelin PS2s, the road noise on my IS decreased a bit. I drove a friend's older M3 with PS2s, and the road noise was just a little less than my IS. Road noise comes with the territory.

    The vibration is caused by a bad camshaft gear. My 06 AWD had the same symptoms. There is a TSB to replace the gear and it was replace free of cost at the dealership in the warranty period.

    The dealers have to be educated!

    Popping noise when braking is caused by the self adjusting/floating brake calipers. The noise is when the brakes "adjust". My car brakes do this every morning. Usually, I hear the noise the first time the brakes are applied. Get a confirmation from a good mechanic and if confirmed, nothing to worry.

    Where is the 'supposed" quality in these vehicles that J.D. Power gives such terrific ratings to, and I wonder if any of the folks from Lexus ever read this postings?
  • mca2mca2 Posts: 20
    The popping noise happens almost every time I turn (slow speed turns). Lexus has had my car for two months.

  • ar39ar39 Posts: 61
    Have you sought a second opinion from a mechanic other than the one at the dealership? In my experience, Lexus mechanics are useless!
  • mca2mca2 Posts: 20

    I just heard back from the dealer and they say it is the engine mount. They told me that when I was turning it would put strain on the bad mount and it would make that popping sound. I am on vacation, so I cannot verify this until after labor day. I will post if this really did fix this issue.

    I notice there's this high pitched humming noise like someone blowing into a flute. I took it to an independent shop thinking it was bearings. They said it was my tires. I have the low profile tires with a v tread pattern. It's the weirdest noise I've ever heard. Have you guys ever heard this noise?
  • ttaittai Posts: 114
    The road noise are the aggressive tires. You'll have to do some googling to find quieter tires. Pickup isn't that bad to me. You have that button on the right, next to the traction control to set it to extra power if you want it. I like getting 25 mpg so I don't use it. Setting it to sport and using the paddles also makes it zippier. My GF has an infinity G35 sedan. Lexus is more Luxury oriented than sports car.

    i had bridgestone potenzas which were failry quiet until aboiut 15k miles, then they started to get very loud. by about 28k, they were extremely loud, and i was disappointing. i had a problem with one tire that neded to be replaced and so i bought a set of yokohama avid w4s. SIGNIFICANTLY less noise. i am much happier now.
  • Hi All. Can someone help with how to remove the GPS control pad in my 04 IS300. Wifes latte spillied in it did it no good. Need to remove and clean buttons.
  • jccai1jccai1 Posts: 106
    I have a similar problem on my 08 IS250 RWD. I hear a metal creaking noise from the driver side front when making slow and sharp right turns. I've brought this up with the dealer twice. Every time, they retightened the front suspension and put some lube on it, and the noise would go away for a month. Then it would come back. Since it's not that bad and doesn't seem to affect how it drives, I've come to ignore the noise. Please post if anyone knows of a permanent fix. It is disappointing for a new, high end car to have this kind of recurring problem, especially one that claims to be one of the most reliable.
  • ALL the factory GPS have at least one drawback. The IS250 is a lot more fuel efficient than the G35 so don't feel too bad about not geting the G.
  • mca2mca2 Posts: 20
    Sorry for not posting a follow up to my post. Yes the noise is gone. Over 1K miles with no popping sound. The dealer said they took one suspension piece off my car and put it on a loaner car until they eliminated the suspension. After everything was tested and my car was still making the popping sound they discovered it was the nut that held the engine mount. Two months in the shop for a nut....

    Is there a recall for the floor mat problem?
  • Yes - there is a recall on IS floor mats. My belief is that it is a recall of the carpet floors mats, and not the Lexus rubber ones which "hook" to the floor. I understand that there has been at least once accident where the carpet floor mat was pushed up under the accelerator pedal and caused the driver to loose control. A friend with an IS250 took her car in for service tnad the dealer removed the floor(s) from her car while it was in. That being siad, I havenot received a formal ecall notice yet and am not sure what Lexus plans on replacing them with.
  • well it started on a rainy day when i tried to pass a car up and my rpms jumped up and my car slowed down and it no longer goes faster then 5 mph and the rpms just rev up i changed my fule pump and check my catalyst converter and thats not it. can someone please help me out lexus 1991 es 250
  • Had the 3rd one today (cold day). Ayone else have a problem with false tire pressure warnings and know of a solution?

    Lexis service manager is checking to see if the sensors can be adjusted.
  • We had a week of very cold weather here last winter. Tire pressure monitor light came on and was on for a week. Once I realized that it was the temperature that was causing it I ignored it. Light went off the next week when it warmed up a little.
  • i have a 2008 IS 250 AWD and need new tires. i currently have bridgestone potenza re92 and i am not happy with the wet handling ability. tire selection is limited in this speed rating. 225 45 17 91V. any recommendations on dunlop sp sport 5000 or continental contiprocontact tires or any other tires.
  • samiam_68samiam_68 Posts: 775
    I would stay away from Dunlop - I had SP 5000's on my GS and they kept getting punctures. Very fragile tires. I have Yokohama Avids V4S now and they are excellent in dry and wet, average in snow. Very sturdy tires - no damage whatsoever after 25K miles and they still have a lot of tread left.
  • ajmtbmajmtbm Posts: 245
    i have yokohama avid w4s they were much quieter and handle much better in the snow than the bridgestone potenza that came with the vehicle.
  • I own a 2002 IS300 and have had trouble with the coolant tank hose resting on the drive belt. It started with a rattling/swishing sound in the passenger side of the dash. When the mechanics checked it out, they found that the hose had been cut because of the drive belt. This was back in 2004 and the hose was replaced, free of charge. It is happening once again and I'll be taking my car in on Monday. The mechanic said the hose shouldn't have been on the drive belt. I believe this to be a defect in the car and I don't believe I should pay for this. Anyone else with this problem?

    These days I've heard news about a Toyota-Lexus recall that includes the IS250 2010. I 'd appreciate any feedback/experience about this recall... What I have to do? Take my car to a Lexus dealer Service Department.

  • loucopitsloucopits Posts: 103
    On a previous 2006 IS250 recall the service department contacted me when they had the parts required. They gave me a loaner, washed my car and filled the gas tank.
  • Your dealer will contact you. Make sure you take you car in with a near empty gas tank. The dealer is supposed to fill your tank as a goodwill gesture. I drove in on fumes earlier this year for a recall on my IS350, and my local dealer filled the tank without hesitation.
