Toyota Prius Reviews

The air conditioner compressor is defective in these cars and they should be recalled. They are expensive items(2,000repair.) For that kind of money they should not fail. Toyota needs to address this problem. They fail at about 70,000 miles.

My 2008 Pruis started blowing only hot air when the AC was on. I took it to a Toyota Dealer. Who had me bring it back Four times, saying they was puting dye in with new coolant looking for a leak.
In the end I had to pay over $1900.00 for the air conditioner to be fixed.They replaced the evaporator box and a valve. Is this the normal cost for this problem in the Pruis's. Very expensive labor.
What started as a way to save money on gas has been very costly. They kept the car for a week and did provide a loaner car. But if my car is going to start breaking down with less than 40,000 miles on it. I think I might as well forget any saving and get a different car.

Transmission Issues at 150K

Love the car but there are two problems. 1 the headlight bulbs need repalcing every 6 months. 2. the factory installed JBL E7022 radios are junk. I bought this car new. the sales person talked up the stereo / Nav unit. worked fine for over 2 years. now needs to be replaced at a cost of $1500+. talked to dealer, Toyota, and JBL no one wants to help, no one cares. The JBL E7022 is costly junk. and I will not be buying another.

Purchased my 2004 Prius used in 2006. Love it 90%. Great mileage - I can get up to 50mpg in summer and 35-40 in winter (Minnesota). Seating could be more comfy - a little stiff. Also, 2004 fog light lenses break easily and they are expensive to replace. We added an after market (installed by Toyota recommended service) heated seats and I LOVE that option. Surprisingly this car carries tons of stuff we haul around. Only car we've had that my husband says he'd buy again.
