Replying to: snevets23 (Feb 03, 2007 8:06 am) 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.

Replying to: bcleveland (Mar 24, 2007 5:48 am) 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. |

Replying to: emontgomery (Jun 28, 2006 5:44 pm) 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.

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.

Replying to: jcorwin1 (Dec 28, 2007 8:03 am) 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.

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!
