Toyota Prius

""12v battery will randomly completely discharge requiring a jump start. Happened three times within a couple months. Battery was replaced with a new one after the first failure. Investigation after the following failures didn't discover any systemic problems. Purchased an emergency jump-start battery that now resides in the glovebox, just in case it happens again.""

""The Prius wouldn't start, and I had to get a replacement battery. This was the secondary battery, not the major one. Since the car was in the garage, I had the repairman come and replace the battery. There were no other problems with the car. This is the only problem I have ever had with the Prius.""

""Many varied lights came on on the dashboard, the cruise control kicked off and would not be set again, and braking was a touch more difficult. I think I might remember it being about the master cylinder? I had too many miles before the problem happened the first time, so the recall did not cover my vehicle. It has happened three winters in a row, and has always recovered by itself...so far.""

"This was a pain mostly due to supply issues. No one had any in stock, and we had to wait for them."

"When shifting from neutral (stopped) into first gear, or sometimes when accelerating from a low spead, loud rattles occur. Maybe transmission?"

"Same problem as mentioned previously. Hard to tell if noise is interior or exterior"

"Lost use of battery pack while on freeway about 15 miles from home. Pulled over to freeway shoulder to consider stopping or continuing driving home and then drove home. Had car towed to repair shop. Ordered replacement battery (but later cancelled). Rodent chewed some of the wiring from the battery pack. Minor cost to repair and electric/hybrid battery was still charged. Repair shop quickly discovered damaged wiring and repaired for $50. No battery damage and battery was still charged. I had the repair shop change oil and do a brake job because they were so honest. Car runs fine!"

"Acid was leaking from the battery and needed to be replaced. It had a ten year/100,000 mile warranty but the car is 11 years old so I had to pay for it."

""Nov 2024, car shook on cold start, check engine light came on. Finally correctly diagnosed in May, 2025.""

"In 2022 the headgasket started leaking and needed to be replaced. Very expensive replacement. No issues for 3 years since its been replaced so far."

"Overcoat on hood began to peel"

""The paint on the roof and adjustent surfaces developed a mesh of cracks and begins to peel. The estimated cost to repaint is close to $2000. It's too much to spend on 11 year old car, so I will keep driving as is.""

"I didn't know about the problem until I took the car in for regular service when the "maintenance" light turned on in my car."

"clogged EGR system. Engine surges at light throttle"
