2004 TOYOTA PRIUS Complaints

The odometer on my 2004 Prius stops at 299,999. This is a known problem in the 04-05 models that was corrected in 2006. Leaves me unable to track miles for maintenance and other uses. This also has the problem with the entire digital dash going dark which means no speedometer or gas gauge. Making the vehicle almost unable to be driven safely at this point. I have reached out to Toyota and they verify that it was an issue with this year range but because I have owned it too long they don't do anything about it

During a hot period of summer, my drive selector decided to not stay in the drive position unless I held it there. I could make the initial selection of drive and then stop on the gas, but it would not stay unless I physically held the lever down in the drive position. I never had an issue with the reverse position; only drive. I could always get the car back into Park. This is an extremely unsafe driving condition because it happens without warning and the fix is not obvious. Once the driver is aware of the fix, it forces them into an unsafe driving condition: driving with one hand on the parking selector. Once cooler weather came, the issue went away. It didn't happen on all hot days and was intermittent. I replaced the drive selector in 2022 and have only had the issue come up one other time since replacing this part.

The contact owns a 2004 Toyota Prius. The contact stated while driving approximately 30 MPH, the vehicle stalled. The vehicle lost power steering functionality but the contact was able to safely pull off of the road.

I need your help to get Toyota to fix 2 items: -ABS Accumulator: I understand Toyota at one time had a recall on the ‘ABS Accumulator’, that may have expired. At that time, I did not have any issue, nor was I aware of the recall. Now the ‘ABS Accumulator’ has gone out and is really hurting the braking. I had to get new brakes & they get locked because of the ABS malfunction. It is an expensive item – more than the cost of the car. I intend to keep the car for a long time, if Toyota can help me get the ABS Accumulator fixed? -MFD: The Multi-Functional Display (MFD) in the middle of the dashboard, has gone blank. It used to just partially blank out before, but now the whole screen is blank all the time, making it very hazardous to drive. Obviously, there is nothing I have done & it is a manufacturing defect, because it should last the life of the car. Please have Toyota fix the 2 problems (ABS & MFD). All requests to Toyota have gone unfulfilled. Your help is needed & will be greatly appreciated.

Toyota has issued time-limited 'Warranty enhancement program ZG1' instead of working with the NHSTA to issue a comprehensive BRAKE ACTUATOR ASSEMBLY RECALL. ZG1 was explicitly in place only from April 2016 to Dec 2017, requiring dealer verification of an actual system failure prior to 31 Dec 2017. My failure occurred in 2021 and Toyota will not extend ZG1 for me (case 211015000390). Obviously the BRAKE ACTUATOR is a key safety component. Obviously this is a design flaw - brake systems MUST be designed to last the life of the vehicle. Obviously Toyota has had an excessive number of failures. Toyota is improperly using this 'warranty enhancement program ZG1' to avoid the NHSTA and to avoid responsibility for the poor BRAKE ACTUATOR ASSEMBLY design. Per their letter to owners, Toyota was NOT replacing the BRAKE ACTUATOR ASSEMBLY on a preventive basis prior to actual brake failure. Because of the importance and severity, Toyota should have replaced the BRAKE ACTUATORS via a recall. I would like Toyota to fix my faulty brakes at their expense.

BRAKE ACTUATOR WENT OUT AND DEALER SAID TOYOTA USED TO COVER IT, BUT NOT ANYMORE. I SEARCHED THE INTERNET AND DISCOVERED THIS [PART IS BAD IN MOST PRIUS VEHICLES AND TOYOTA EXTENDED THE COVERAGE ON THE 2010-2015 UNTIL AUGUST 31, 2021. UNFORTUNATELY MY CAR IS 2004 AND DOES NOT GET THE BENEFIT OF THE EXTENSION. THE COST TO REPAIR IS ALMOST $4,000. TOYOTA KNOWS OF THIS ISSUE AND SHOULD REPAIR MY CAR AS THEY ARE WITH THE OTHER YEARS 2010-2015. THIS IS A DRIVER SAFETY ISSUE.

ALL THE INSTRUMENT CLUSTER LIGHTS CONTINUE TO GO OUT ON MY 04 PRIUS. I DON'T KNOW HOW MUCH FUEL I HAVE THIS COULD BE A SAFETY ISSUE. I DON'T KNOW HOW FAST I'M GOING THIS COULD DEFINITELY BE A SAFETY ISSUE. AND ZERO WARNING LIGHTS COME ON THIS IS DEFINITELY A SAFETY ISSUE. BY LOOKING ON THE INTERNET I CAN TELL THOUSANDS OF PRIUSES HAVE THIS EXACT SAME ISSUE WITH THE INSTRUMENT PANEL CLUSTER GOING OUT. THIS SHOULD DEFINITELY BE A RECALL.

MY LEFT HEADLIGHT GOES OFF BUT IF I TURN THE HEADLIGHTS BACK OFF AND BACK ON IT COMES BACK ON. THE HEADLIGHT IS NOT BURNED OUT. THIS HAPPENS WHILE ON THE FREEWAY IN THE DARK WHILE RAINING. THIS HAPPENS INTERMITTENTLY AND NOT ALL THE TIME.

ABOUT 1.5 YEARS AGO DURING A VACATION. MY CAR DECIDED TO NOT SHUT OFF. I DROVE TO THE NEAREST DEALERSHIP THAT WAS ABOUT THE CLOSE. THEY ASSISTED AND SAID TO HOLD THE POWER BUTTON DOWN UNTIL IT SHUTS OFF THEN TURN IT BACK ON. THIS WAS A DEALERSHIP IN GEORGIA. THE MECHANIC HAD HEARD OF THE PROBLEM BEFORE. I RECENTLY HAD THE FRONT DASH LIGHT GO COMPLETELY OUT. I DID NOT HAVE AN INSTRUMENT PANEL AT ALL. THE WAS NOT A WAY TO SEE MPH, GAS GAUGE, WARNING LIGHTS, NOTHING. THE CENTER MONITOR STAYED ON. IT TOOK 2 DAYS BUT IT CAME BACK ON. A WEEK LATER IT HAPPENED AGAIN AND AGAIN CAME BACK ON. WARNING LIGHTS CAME ON AND I DROVE TO DEALERSHIP. IT WAS THE 2ND WATER PUMP GOING OUT. AS I WAS LEAVING MY DASH LIGHTS WENT OUT AGAIN. I TOOK IT BACK INTO THE PRIUS DEALERSHIP. THEY HAD PAPERWORK STATING THERE HAD BEEN ISSUES WITH THE METERED DASH BEFORE. IS THERE A RECALL ON IT OR NOT? I HAD TO HAVE A CAR AND WAS ALLOWED TO LEAVE WITH THE DASH NOT WORKING. I DROVE TO A GAS STATION. AFTER FILLING WITH GAS THE DASH LIGHTS CAME ON AGAIN. I HAD TO PAY FOR THE METERED DASH PART TO BE ORDERED UP FRONT BECAUSE THE MECHANIC SAID IT MAY COME BACK ON. THERE SHOULD BE A RECALL ON THIS AS IT IS AN ONGOING ISSUE. THE MECHANIC EVEN CALLED IT A SHORT. DUE TOT HE PAPERWORK THE DESK REPRESENTATIVE HAD, IT APPEARS THERE HAVE BEEN SEVERAL REPORTS BEFORE ON THE METERED DASH SHORTING. PLEASE HELP. I NEED THE CAR AND CANNOT AFFORD THESE RIDICULOUS PRICES FOR MANUFACTURER MISTAKES.
