2003 Toyota rav was stop instead of accelerating on highway starting 12/17, brought to dealership on 12/22/09 and they changed spark plugs; brought back 12/29 they changed water pump and then test drove and called me to tell me it could be transmission but to replace the ecm first since they knew it could cause transmission problems.
Inspect and replace water pump and serpentine belt on Feb 2009, engine issue again Feb 2012 check engine light is on/flashing - estimate $955. 98+tax - four wheel alignment $69. 95+tax tech road tested and found front sway bar end links are worn/loose $435. 82+tax (repairs completed) Feb 2012 brake noise ~|~customer states noise when braking ~|~front and rear brake inspection done at this time ~|~inspection only no concerns found at this time (another mechanic replaced entire front brakes shortly after as they were found highly damaged) transmission service ~|~customer requests transmission service w/differentials ~|~maintenance ~|~drained and refilled automatic transmission fluid w/transfer case and differentials as needed (less than year later had trans fluid again replaced as continued issues) now is seemingly worse and more often. Step on gas and nothing happens for several seconds then jerks forward, loud thunking sound, extremely dangerous to drive as unknown when it will occur. Have not been using vehicle very much because of it. If this issue was known about in 2006 why was this never repaired before I even bought it or notify me of when I took it in for services on several occasions?.
