WHEN DRIVING IN TRAFFIC HYBRID BATTERY COMPLETELY DISCHARGES CAUSING CAR TO LURCH WHEN TRYING TO ACCELERATE.

TOOK TO TOYOTA DEALERSHIP PAID NEARLY $300 FOR DIAGNOSTIC AND THEY COULD FIND NO ERROR CODES RELATED TO THE PROBLEM. CALL CHP TO ASSIST IN TOW TO DEALERSHIP. *TR

I JUNE OF 2202 I BOUGHT TOYOTA PRIUS. I WAS GETTING 44MPG ON THE HIGHWAY AND 49 IN THE CITY. THEN THE COLD WEATHER COMES AND NOW I GET ONLY 35MPG IN THE CITY THAT IS A DROP OF OVER 28%. I HAVE TAKEN IT BACK TWICE TO THE DEALER AND THEY SUPPOSELY SCOPE IT AND SAID THAT THERE WAS NOTHING WRONG AND THAT THE COLD WEATHER WAS THE PROBLEM. I TOLD THEM THAT THEIR EXCUSE WAS LAME AND THAT WAS NOT EXCEPTABLE. IF A CARS GAS MILEAGE DROPS THAT DRAMACTICLY THERE HAS TO BE A PROBLEM OR THEIR IS A MANUFACTURING DEFECT. THERE SHOULD NOT BE A 28% DROP OFF IN A CAR PERFORMANCE IN COLD WEATHER. THERE ADVERTISEMENT PITCH WAS THAT THE CAR WILL GET BETTER MILEAGE IN THE CITY THAN THE HIGHWAY BECAUSE OF THEIR HYBRID SYSTEM, IT DID NOT SAY THAT THE SYSTEM ONLY WORK IN WARM WEATHER
MY TOYOTA PRIUS HAS HAD MULTIPLE AUTOMATIC FAILURES SINCE IT'S PURCHACE. YOU WILL BE DRIVING DOWN THE ROAD AT ANY SPEED AND IT SHUTS STALLS. THIS HAS HAPPENED ON THE HIGHWAY IN MA., ON THE ROAD IN NM, ON THE HIGHWAY IN NM AND ON THE HIGHWAY IN TX. I HAVE BEEN LUCKY SO FAR THAT I HAVE NOT BEEN KILLED. I HAVE COMPLAINED TO DEALERS IN MA, NM, AND TX AND THEY CLAIM THAT THERE IS NOTHING WRONG WITH MY CAR. MY CAR SLOWS DOWN TO 40 MPH GOING UP HILL WHICH IS ALSO A DANGER WHEN YOU ARE IN A 60 MPH ZONE ON THE HIGHWAY. THE MILEAGE HAS BEEN POOR AROUND 30 MILES PER GALLON. MANY PARTS HAVE BEEN REPLACEDUT THEY ALWAYS SAY IT IS IN MY HEAD THAT THERE IS SOMETHING WRONG WITH MY CAR. I PICKED IT UP FROM A DEALER IN NM AND DROVE IT LESS THAN 2 MILES AND IT STALLED WHILE DRIVING ON A BUSY ROAD AND I AGAIN WAS ALMOST KILLED. THEY MECHANIC TOLD ME THERE WAS NOTHING WRONG WITH MY CAR AND THAT HE WAS GOING TO PUSH IT OUT INTO THE ROAD AFTER HE PULLED OUT SOME PARTS I REFUSED TO PAY FOR AS I WANTED TO WAIT A DAY UNTIL I COULD TALK TO THE TOYOTA 1 800 COMPLAINT LINE. THIS IS A REAL PROBLEM THAT TOYOTA IS NOT ADDRESSING AND HAS TAUGHT THEIR MECHANICS TO BE CONDECENDING AND RUDE TO FEMALE CONSUMERS.
