2010 Toyota Prius Owner Comments

problem #5

Prius 4 4

  • Automatic transmission
  • 105,000 miles


Dealership is telling me this will cost over $3000 to fix. I am hearing about a recall for my model year but I have never received a notice about this. I have received other recall notices in the past but this problem scares me. Not only do we not have the money for this repair, this our only vehicle and my wife needs the car to go to work.

If there is a recall, we need to know about it. The dealership seems to be playing games.

Thank you!

Prius IV

  • Automatic transmission
  • 159,214 miles

On May 15, 2020, my ABS, brake,VSC and traction lights came on and my brake peddle felt weird. I immediately took it to Mike Erdman Toyota in Melbourne, Florida. From the moment I came in and the ASM looked at the vehicle, she was convinced it was the brake booster assembly. I was told that they have seen a number of these repairs. I was told it was a very costly repair. The tech was able to pull DTC C1391 (brake accumulator failure). I was advised that it would cost me $3,000 to repair. There was an "enhanced" warranty for this very problem that expired on November 30,2019. During that time your vehicle had to experience the problem/failure for Toyota to fix it. It was a service campaign, not a recall. I contacted Toyota Motor Sales to see if I could receive customer assistance for the problem (case#2005150765) I have owned my car and have been the sole driver since October 31,2009, all my services (excluding tires) have been done at Toyota dealerships. Overall a GREAT vehicle with 159.214 miles. After explaining that as well as the fact that my vehicle was only 5 months outside of the "enhanced" warranty/TSB for brake booster/pump assembly issues I was flatly told there was nothing that they would do to assist. I declined repairs and picked my car up from the dealership. On May 17, 2020 I filed a complaint with NHTSA (#11324851) indicating that if Toyota knew of an existing issue w/ brake booster/pump assembly, why didn't they just do a recall instead of a service campaign to wait and see if it actually happened. Toyota NOW has a campaign for 2011-2015 Prius for the same issue. It ends in April 2021. I am frustrated since this is not what I expect of Toyota. This costly repair falls on my shoulder to repair while they knew about this ongoing issue and gave it a wait and see attitude in case it occurred. BRAKES ARE A SAFETY ISSUE!

Prius III

  • Automatic transmission
  • 120,000 miles

2010 Prius III with 120,000 miles. On March 31, 2018 I was having severe issues with my brakes - I could not stop. The car was taken to my local dealership and left there over the weekend. The following Monday I was told that my brake booster is leaking and needs to be replaced. The cost: $3,600, which has rendered my car worthless.

I did some research and learned that countless Prius owners have faced the exact same issue, and the 2009 model had the same issue and Toyota covered the repair through a recall/customer support program. Whether you had this problem or you are currently having it, call corporate at 800-331-4331 and tell them what happened. If enough people call, Toyota will cover the repair or reimburse you for what you had to pay to fix the problem through a customer support program. This will be my last Toyota.

Prius 1.8L

  • CVT transmission
  • 79,700 miles

11/3/10. - Purchased 2010 Prius from Arlington Toyota with an extended 7yr. / 100,000mi. Bumper to Bumper Warranty 11/3/10 to Present - Serviced only by Arlington Toyota other than oil changes while traveling. Jan. 26 - Prius serviced in January 26, 2016 for normal service at Arlington Toyota. March 29 - Date of accident, family friend was driving Prius home from Gainesville - Noticed brakes were squishy and the HAC light had come on from time to time. Dropped friend off at home & proceeded to return home. Stopped at a light, foot on brake and rolled into a truck, damaging my car. No damage to truck. Upon arriving home, pulled into driveway - pushed on brakes like at a traffic light. Brakes failed. March 30 - Called Arlington Toyota and told them of the problem. They said they were sending a tow truck and to call this number and make the arrangements , so I did not call AAA for towing. When I got to Toyota, I was told that this would probably take a week, so I rented a car from Toyota Rent a Car, since I needed a vehicle to get around town. I was informed at that time that if it were a “Part” problem, the 7 year 100,000 mile policy that I purchased with them for the Prius would cover the rental costs. April 1 - Greg Brown (Service Director) at Arlington Toyota told me that they had a problem reading the codes that they were getting on the Prius and that they were working with the Toyota to have that resolved. Did not hear back from them until April 5. April 5 - I was informed me that this would have to be turned over to Southeastern Toyota and that a third party would look at computer info and car. Told me that they had 30 days to preform this. Rented car for one more month from Toyota Rent A Car at April 11 - Had a call from Arlington Toyota to come and get the Prius. Still had not heard anything from Southeast Toyota. Refused to move car unless they signed paper stating that they were liable if anything happened due to the brake problem.They kept the car. I was told that I had to initiate the call to Toyota SouthEastern to get things moving. Was under the understanding that Arlington Toyota was doing that. Emailed a signed release form to check the codes.Toyota Data Imaging Auth. Form to Toyota Customer Experience. April 14 - Had returned car and now Re-rented Car April 29 - Called (Shanizy) at Arlington Toyota and he said Kenneth Polite, the Toyota tech (a third party person) had just inspected the car (That was around 1:00pm) I went down there and waited till 3:30pm to talk with him and he never came out to talk with me. Re-rented Car again. May 31 - Letter from Toyota Motor Sales, USA, Nick Rojas Legal Department) saying Brakes are operating as designed - computers read clean. HAC light came on never brought up in letter. The problem identified from Kenneth Polite was that the floor mats were improperly installed and that I should refer to the Owners Manuel. June 6 - Returned rental Car. Prius towed to Gerber Collision & Glass for body damage. June 22 - Prius released from Gerber. Prius moved to Pope Automotive for inspection of braking problem. Within 20 minutes they diagnosed the problem. The Master Brake Cylinder leaking back into itself. Took video of problem with Prius. I gave them letter from Nick Rojas of Toyota Motor Sales, USA stating that the brake pedal was operating as designed. Got a good laugh out of that. June 24 - Harvard Ins. sends (Mike) out to Pope Automotive to inspect Prius on what had caused the accident. Pope Automotive calls Fidelity Ins. Co, the underwriters for my Toyota Extended Warranty to file a claim on faulty part purchased from Arlington Toyota at the time of purchase. Requests that someone from their company come out and verify that this is in fact what caused the accident. He comes out several days later and has the problem happen to him. Authorizes replacement of part. June 27 - Collect all information and update timeline in preparation of a conflict with Toyota. July 1 - Sent letter to Nick Rojas (Toyota USA) July 5 - Nick Rojas receives letter. Never responds. Have to have the operator at Toyota North America to get him. Than returns call and is very rude to my wife. Tells me that Mr. Polite has the final say about it. Asked him about the dent in my left rear quarter panel that I didn’t have when the car was towed . He just said, ‘Prove it”. The phone conversation did not end on good terms. July 7 - Sent email to Casey Crowell (Southeastern Toyota) (Think he is Kenneth Polite’s boss), with my thoughts about the quality of his work. August 4 - Contact Arlington Toyota start things happening. Talked with Roger Page (Used Car Manager) and he say”s “Yes there is a problem. Turns me over to Lee Bay (Service Director). Who say’s “Yes there is a problem and he will submit all this to Toyota to get this cleared up.” Come to find out that Kenneth Polite has been fired. Sept. 29 - Now it’s time to Call Ken, or better yet, write him.

Prius Three 2.3L Hybrid

  • CVT transmission
  • 82,000 miles

Complete brake failure while driving (50 miles from home). Knew immediately it was power booster pump or master cylinder (proved to be the latter). HOWEVER, Toyota in its isdom incorporated the master cylinder into a larger brake assembly including the ABS system controls, so instead of this being a $1000 replacement, it is costing me almost 3 times that! Additionally, no car's brake system (as opposed to pad or shoes) should fail at 80,000 miles!
