Top problems in owners’ words
Verbatim from NHTSA complaints, newest first
Electrical system
45 reports1 crash1 fire
“After getting gas, the vehicle will not start. It will crank and crank but not turn over, like it is starving for gas. Then after 10-15 minutes it will start barely and to keep it running I have to floor the accelerator. Any other time it starts just fine. There are also no codes causing a check engine light.”
Power train
45 reports2 crashes
“Car suddenly began to slip out of gear and have difficulty shifting smoothly. After having car examined by 2 repair shops it was determined the UA80 Transmission needed replaced. Repair shop advised car was not safe to drive with this condition. Warning lights for Check Engine and Check AWD system and traction control came on at the same time as the slipping and rough shifting.”
Engine
42 reports2 crashes
“During the Multi Point Inspection, technician inspected the vehicle. He checked the engine, transmission, and cooling system, topping off all fluids. However, the engine was failing inspection as there was oil underneath the vehicle, which was also seen around the engine, due to an oil leak.”
Service brakes
27 reports5 crashes
“With 22k miles on vehicle, car won’t start due to Brake power low fault. Battery was replaced in attempt to rectify problem with no success, vehicle will need to be towed in for repair.”
Fuel/propulsion system
26 reports1 crash
“Toyota manufacturing issue-fuel line is manufactured incorrectly-had gas seeping into cab of vehicle and tailpipe. Severe safety issue Steering wheel/column sticks and almost lose control when driving due to a worn out coupler-poor design and manufacturing.”
Visibility/wiper
13 reports1 crash
“There is a splotchy glare that appears on my windshield that makes it EXTREMELY difficult to see out the windshield in the rain. It is not fog, I have cleaned the inside and outside of the windshield, changed the wiper blades, tried the heated windshield feature, defrost, and seriously done everything and it does not go away unless direct sunlight is on it. Forget driving in the rain at night, I was unable to see the lines in the road and it's worse when headlights are facing your direction. I ran off the road and had to park my car until the rain passed. This is absolutely dangerous. The guys at the dealership were stumped as well. It happened to be raining as I was leaving after service and I showed him and he had no idea. It is across my entire windshield. Sometimes it depends on how light is shining on it. This needs to be a recall before someone is seriously hurt.”
