What owners wrote

A few complaints as filed, shortened and with personal details removed. The first ones are among the most serious reports for this model year; the rest are typical.

It was raining and I was entering highway, I had my left turn signal on and started to accelerate. The car started to fish tail and when into a 360 degree spin, maybe twice, at least 1 1/2 times. When I came out of spin I crashed into the cement median. At no time did the vsc (vehicle skid control) activate. It is something that you can't miss. A lound warning sound comes on and the dashboard lights up with a skid warning. It had happened once before in the snow.

October 2001 CrashInjury

Lexus ls 400 1999 model. Dangerous hesitation upon acceleration. Further after driving this car for two years, I have neck pains from the daily whiplash. Toyota is igrnoring this system wide. It is an outrage. Its damaging peoples necks all over the country. They will not fix it - they claim its normal. Other dealers are telling customers about it - - my wife refuses to drive my car - it's dangerous!

Reported at 130,000 miles, September 2012 CrashInjury

I am reporting this because it might provide a clue to the toyota racing engine problem. On each of two days before I took my 1999 lexus 400 to the dealer for repairs, the engine would race at an estimated 4,000+ rpms and emitted a grinding sound as the car was started. After turning off the engine with the key, the car would restart without a problem. Strangely, the dealer did not record this particular complaint, but stated that diagnosis revealed that starter was failing.
