Lincoln LS: rapid acceleration problems????

My mother owns a 2002+/- Lincoln ls v8 that has just about every option. She tells me that every once in a while the car will accelerate by itself and the only way she can stop it is to slam the car in park. I would say driver error but the same thing happened when my sister was driving the car. The dealer says they have never heard of such a thing and there is nothing they can do.

Has anyone ever heard of such a thing, offer an opinion as to what it might be or how to fix it. I NEED SOME HELP!!!

    There's only one way the throttle can be opened.

    "Slamming it into park" certainly isn't the intelligent thing to do. A couple of those moves, and you'll destroy the transmission. A better thing to do would be shifting into neutral, turning off the ignition, or taking one's foot off the gas while applying the brakes.

    I have over 150K miles on 3 LSes (my present 2000 V6 has 126K miles, had a 2001 [bought used] putting on 30K miles and our present 2006 with 7K miles). I have never had an episode of unintended acceleration. The pedals are relatively close and if one's foot isn't completely off the gas pedal one could be pressing the brake and gas simultaneously. I have done that before.....

    Just because it has never happened to others, doesn't mean the problem doesn't exist. Sicne there are no "reported" cases, I would look at the things that could possibly go wrong that could cause this problem. No being a mechanic, I would make sure I didn't accidently hit the acclerator instead of the brake. maske sure the carpet isn't interfering wiht the pedals (happened on my Explorer a few times). Check th eaccelerator pedal to make sure there isn't any build-up that may cause it to stick. Take a venture under the hood and clean the throttle body. Amazing how much gunk gets caught in there after a few years. visit the NHTSA website and see if there are any TSBs for this problem.

    Good luck
  • I SELL LINCOLNS AND HAVE HEARD THIS PROBLEM BEFORE FROM CUSTOMERS..TRUST ME..ITS USER ERROR..IVE HAD CUSTOMERS DO IT RIGHT IN FRONT OF ME AND IT WAS BECAUSE THEY HAD THERE FOOT ON BRAKE AND GAS..IM ALSO THE OWNER OF 2 LINCOLN LS'AND THE ACCELERATION PROBLEM IS A HOW THE CAR WAS MANUFATURED..THEY ALL DO IT TO AN EXTENT..IT DOES KINDA OF JUST KICK RIGHT IN..BUT I STILL LOVE MY L.S.!
    2006 LINCOLN LS..LOADED..
  • You may sell Lincolns but that doesn't mean you are an expert. This has happened to me. And it is not due to driver error. read on... I purchased a 2000 LS V8 in 1999. It has 130K on it and have had no problems with the exception of a Sticking Throttle. It has happened a few times. I have taken my foot off both accelerator and brake, tried slamming on the gas pedal and nothing works except pulling over, braking hard and turning off the engine. The tachometer read a constant 30K until I turned off the engine. Upon starting it up, it was back to normal.

    Whoa! Tach read 30K? Man, isn't that over the red line?
  • Cheap gas will gum up the throttle body and cause the butterfly to stick. That has happened to me with other cars, but never with my 135K mile 2000 V6 LS.
  • OK so I had a typo....I meant 3K. I'm just a dumb blond.
  • On 1/31/07 while slowly reversing up a sloped driveway, my 1992 Lexus 400SC suddenly accelerated rapidly and uncontrollably. It felt as if I was in a rocket ship! Although I slammed on the brakes, I could not stop in time to avoid a car parked in the driveway. Luckily, there were no injuries (grandson was in car). This is my first accident in 42 years. While I hear that some conclude that I mistook the accelerator for the brake, I KNOW that's not true. My foot was on the accelerator to begin with since I was slowing giving the car gas to climb the incline. Weather conditions were clear, no obstacles on the floor, and I was wearing normal shoes... no boots or heels. This accident was NOT my fault, but I don't know how to prove this since the problem is intermittent. I have filed an incident report with both the police department and NHTSA and have sent a certified letter to Lexus in CA. However, there is strength in numbers and need to hear from others who have experienced this frightening experience. If you research this further on the web, you will find that many drivers have experienced this throughout the years, not only with Lexus and Toyota, but with other manufacturers, as well. Some "experts" refer to the problem as a defective electronic throttle control system. However, I don't know what caused my particular problem. Unfortunately, car manufacturers are not upfront with this situation.
  • snevets23,
    I've just experienced a similar problem with my 1994 Lexus. Dropping off my child, I put the car in Park, only to have the engine start accelerating and decelerating repeatedly. On the drive home - fortunately in the neighborhood - the car accelerated by itself with me "riding the brake" to keep it slowed down, while at the same time the dash went completely dark - no lights, radio - the windows moving very slowly.
    At home when I turned the ignition on and off again, the lights worked though the ignition continued to race, then off and not on again. It was completely dead. Then a few minutes later it once again cranked.
    The next day I had my ex drive it to the shop, where we were told there was a severe electircal problem and in fact smoke coming from the dash during their diagnostic. we were advised to tow - not drive - it to the dealer an hour away.
    I've decided instead to junk the car. It was to go to my 17 year old daughter and I'm not taking any chances. I paid 4K for it 2 yrs ago and its just not worth an expensive timely repair - especially when I've read all over the net regarding similar problems - and as a single Mom I can't afford to be without a dependable car.
    This was a great car until this happened. had over 150K on it with no other problems while I owned it.
    Hope this helps.

    Dear "BCleveland",

    Thank you SO much for your input concerning your 1994 Lexus
    acceleration problem. Although this was a frightening and now costly experience for you, I'm glad to hear that no injuries or property damage occurred. I'm still on my own private "campaign" to find a resolution to my Lexus uncontrolled acceleration problem. The car came back from the body shop just last week (almost two months), but it "sits" in my driveway as I'm afraid to drive it again. At my request, The National Highway Traffic Safety Administration sent me copies of similar reports throughout the years of the same problem involving the Lexus SC 400 model.... imagine how many other reports there must be concerning OTHER Lexus models....and other car manufacturers, we well! Imagine also, how many people just NEVER TOOK THE TIME TO FILE A REPORT! At first, my calls and certified letter to the Lexus Corporation in California requesting a specialized diagnostic inspection resulted in a reply that they were sorry but "we must decline any assistance in this matter". However, more persistence has resulted in a scheduled inspection next week by the Lexus' traveling diagnostic technicians at my closest dealer. At this point, I'm grateful for this latest development and hope that this team will find and replace the problem part. I suspect a computer/electronic malfunction (throttle?); however, the problem is intermittent. However, I'm certain that no one from Lexus would want their wife or mom driving MY car after KNOWING its history and, hopefully, will be considerate of my well-being also. Before you junk your Lexus, perhaps, you should pursue this also although I realize that working, single moms don't have the luxury of extra time to devote to such time-consuming matters. Anyway, thank you again for sharing your experience on this website.
  • this has just happend to me with a 2008 tacoma in a drive thru out of control with rubber burnibg tires and in the end i hit some one this is not human error because my foot was already on the brake at the time and stopped ready to place my order toyota said nothing showed on the computer i think i am in for a fight this tacoma has 1000 miles on it and i will not drive this auto would you not knowing when you will take off
  • My 2000 Lincoln LS V8 is having what may be the same acceleration problem. It occurs intermittently and without warning. When it occurs, I can take my foot off the gas and it will accelerate on it's own and when I put in park or neutral, the RPM rises to 3K. It stops after it's been off for a little while.

    No one seems to know what the problem could be. My Lincoln dealer has attempted to repair it 3 times and another mechanic couldn't figure it out. The challenge is that they can't duplicate the behavior. The dealer was only able to do it once. My other mechanic suspects a computer may be causing it.

    They changed the air bypass valve and it stopped for a few weeks. Second, they changed the O2 sensor which had no affect. Lastly, they changed the same valve and it worked for a week or so.

    It's been doing this for months, but now it's causing the temperature gauge to red-line. (But, my mechanic told me that it wasn't over heating.)

    I like my car, but I don't know what to do about this problem.
  • akirbyakirby Posts: 7,723
    Did they check the accelerator cable or the throttle body? I can't think of a failure that would cause you to redline at 3000 RPM (the computer limits the revs in Park to 3000 to avoid damaging the tranny if you drop it into gear at high rpm) outside of the throttle cable or the throttle body itself (or possibly the cruise control).
  • thanks for the info toyota is looking into the problem but when this happend the truck was in drive and i had my foot down on the brake as hard as possible and then i put the truck in park and shut it off but by then i hit the car in front of me but the truck tires were burning rubber and smoking any ideas would help thanks again
  • I need some help with my 2000 LS V8 3.9L. I never had a big problem with my car yet luckly!(only thing was replacing the coils), until now. My car now has 95,000 miles on it and my engine is acting up. It has a rough idle and when accelerating it goes up and down while speeding up. I had a code of P0171 (bank 1). I found oil in my spark plug well driver side. I replace valve cover gasket and replaced all spark plugs and coils (No more leaks). Problem still occurs with the idle and hesitations on acceleration. I cleaned out my MAS and still has the same problem. I have a new EGR valve but did not replace it yet. If the new EGR valve doesnt work..then I am stumped on what it could be. Again this is the first real problem that I have faced with my LS so far. If there is anyone out there that might know what can be the problem I would greatly appreciate your feedback.

    Two things:

    1) Your post appears to have nothing to do with rapid acceleration, which is the topic here.

    2) You've posted the same message 3-5 times on various Lincoln LS boards. Be advised than only a few people read anything that has to do with the LS, and we read everything that has to do with the LS. Reading & re-reading the same message is not a good thing. I think they call it cross-posting. It's discouraged.

    Welcome to acquiring an excellent car that is no longer supported by anyone or anything. There's a reason it was cheap when you bought it.
  • Oh okay..thanks for the advice. Yeah this is my first time posting into forums for feedback. So i just figured more i post then better chance for more responses. but yeah i get what you are saying. The post for the rapid acceleration was just plan and dumb on my part for real, now that I think about it. My apologies to everyone! Thanks again!
  • The following is an update to my original 2/3/07 post regarding my 1/31/07 accident involving uncontrolled rapid acceleration with my Lexus SC400. It's been over a year now and despite letters, calls, e-mails, and an inspection by an "expert" Lexus technician, the problem part(s) has never been located and, therefore, the cause remains unknown. The car remains in my driveway to date after 13 months, and no one in my family has driven it in fear of a recurrence. My husband had a similar incident with THIS car one month prior to my experience but, luckily, he was not involved in an accident. I won't trade it in for another Lexus because I won't give this manufacturer anymore new business. I hesitate selling it privately because of its past history. If I knew for certain which part was defective, I would gladly pay for its replacement so that I could have my beloved Lexus back and drive it once again without fear of accelerating uncontrollably--possibly causing another accident...or worse. Unfortunately, it is an intermittant problem making it difficult (if not impossible) to replicate the part's failure. For what it is worth, I filed a report with the National Highway Safety office but never heard from them again. From previous posts and surfing the web, I KNOW there are others who have experienced similar frightening episodes. With all of today's sophisticated technology, I find it difficult to understand why the cause of this problem cannot be solved. Thanks for listening to my tale of woe!
  • as you know i had the same headache with toyota i have a friend who had a trouble with a lexus and call the dispute and settlement company on line and he got his money back this company service is free just go on line and get the numbersi think they go under the name NDSC but i am not sure do not give up toyota covers up until thousands of cars are involved but ny then it is to late for people like us good luck

    I have a 2002 lincoln LS V6 my problem is when i Accelerate it seems like there is no power the car will shif fine but as if there is something stoping it from accelerating smooth i will pull over and trun the it off couple times and its smooth again so thats whats killing right now and all i been doing is spending money and taking it to diffrent mechanics every body at the local Lincoln dealership knows me now i spend about $3800 on trying to fix this problem and still dose that ive had the car for 3 years now and spend over $8000 on it and i am getting to realize buying this car was a big mistake and if anyone knows what it could be please let me know or other wise i will just sell it i am sick of it and its sad because i loved the LS when they first came out and still think it was best styling american car ever had oh well i guess i will just go and get a new toyota camry my old 1992 camry still runs like a dream even though i put 220,000 miles on it thats a car not LS
  • akirbyakirby Posts: 7,723
    I have no idea what you just said. Try using a period every now and then.
  • brucelincbrucelinc Posts: 814
    If I were you I would sell the LS and get a toyota but I am not you so I probably would not do that but if I had a 1992 Camry that ran like a dream I might just keep it and cut the top off the ls and plant flowers in it but that would be pretty silly so maybe you should have a heart to heart talk with the Lincoln dealer service manager and point out that they have not fixed the problem and dont they guarantee their work most dealers try to satisfy good customers and I find it incredible that anyone would spend $3800 chasing a problem that sounds simple enough for a good tech to diagnose

    My wife pulled into a diagonal parking space and as she came to a stop, the car suddenly surged forward went over the curbing and the sidewalk and hit the wall of a commercial building. I have heard of these type acceleration problems with other makes. Any info on this car? It is a 2007 year model.
  • akirbyakirby Posts: 7,723
    Sorry, but all credible information related to unintended acceleration points to driver error - hitting the accelerator instead of or in addition to the brake pedal. If the driver's foot was really on the brake, then it should have stopped the car even if the throttle was wide open. Try it yourself - put the car in gear, hold the brake and nail the gas pedal - it won't move.

    Have the brakes checked, and also make sure the floor mat wasn't in the way. Otherwise it was simply driver error.
  • jron1jron1 Posts: 2
    This was a diagonal parking space on a one way narrow street. When she pulled into thespot and tires rested on the curb, she removed her foot from the brake. This is when the car accelerated quickly, jumped the curb and hit a building.

    As soon as the dealer body shop repairs the car, they are sending it to a Lincoln testing center to check this out.
