What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
While driving on a city street at approximately 40 mph the vehicle started making a loud noise (similar to the sound a dirt bike engine makes). The sound became loluder when I pressed the brakes. I took the vehicle to the repair shop and was notified that the hydrobooster failed resulting in a steering fluid leakage.
Driving thru a heavy rain storm at 50 mph in the left lane of a three lane highway and the windshield wipers stopped working at about a 1/4 of the way up...pulled over as soon as I could ...did not panic...
Now my check engine light is on showing an oxygen sensor failure or catalytic converter. After researching the internet this problem is affecting thousands of people. Something needs to be addressed !!
Check engine light came on and wouldn't go out. Took it to the garage and they pulled up the code po442, evap leak. They did a smoke test and found out the fuel pump unit was all rusted out and also the straps holding the fuel tank in was all rusted out.
At first the washers just kept spraying and wouldn't stop. I had to take out the fuse to get it to stop. I recently put the fuse back in and now it won't work. The washers will just start spraying out of the blue and this is very dangerous if you are driving down the road and you can't get it to stop.
Started smelling strong fuel smells so took vehicle to dealer. Dealer called and asked me to stop back because when they dropped fuel tank they discovered fuel lines running from gas tank were so badly corroded through that were spraying pin-streams of raw gas all over the underside of my vehicle.
