Speed control & acceleration all 43 →
Today, another Lexus /Toyota has an acceleration problem which finally caused 4 deaths. Many of us have had similar experiences. You have 3 at least already listed in your complaints. 2006 Toyota highlanders (3) just took off and drivers couldn't stop them (I am one) until the car hit something. Lexus too, made by Toyota. Please check into this. I wrote Toyota to explain that I did not put my foot on accelerator. I got a generic letter back, without help or explanation. We have a problem with these cars , someone needs to address these unexplained accelerations.. My car flew through the air with me screaming , trying to stop it. I hit headon into a cement side of an irrigation ditch. Passenger is still in rehab since March of this year. Is it just the mats, as the san diego press is suggesting with the death of the chp and his 3 family members? I think not. …
2006 Toyota Highlander hybrid - I was stopped in a right turn only lane. The vehicle in front of me began to make a right turn on a red light. As he moved forward, I slightly released pressure on the brakes and my vehicle lunged forward and crashed into the vehicle in front of me which had stopped suddenly. This "lunging" is a common occurrence in this Toyota vehicle. We had thought it was just an idiosyncrasy of the hybrid vehicle. However, my brother has a newer model Highlander hybrid and he does not experience this lunging. What I mean by lunging is that the vehicle, at times, will lunge forward as you release the brake at higher speed than an idle. In the simple accident mentioned above, my vehicle sustained over $3000 in damage, which is quite an extraordinary amount for this type of accident.
Engine & cooling all 40 →
I can see many complaints similar to mine on line since the car was built in 2006. Driving on a 7hr trip when engine light came on and car overheated. We had to pull over on a busy highway and wait for car to cool down and light to go off. It was scary since I had my child in the car and traffic was moving at 60 mph. The next day I had the Toyota dealer charge me $160.00 to tell me coolant and oil were leaking from the head gasket and the bolt corroded and listed out causing a sealing issue. We just had the car in their shop doing thousands of dollars of maintenance and had a full inspection done in preparation for this trip. We also had fluid leaks from the engine twice before at 65819 miles and again at 84458 miles. No mention of this issue was ever brought up by dealer. I have full records and always did maint as suggested. …
