Air bags
17 reports7 crashes2 related recalls
“I was just in my second front end collision and for the second time, my front airbags did not deploy. The first instance, I hit a deer head on going 75 mph on the interstate. Last week, I T-bone F150 at 35mph - hard enough to make that truck spin around - and had injuries to my head, knee, and hand, and yet the airbag did not deploy once again. In both cases, my car sustained over $10,000 and damage to the front end.”

Suspension
10 reports
“Front Coil Spring Cracking (TRD Pro Models) I observed cracking of the front coil spring, a design defect in the spring's termination and how it sits on the top hat and bottom perch. This can lead to a sudden loss of control and a crash. Furthermore, pieces of the broken spring coil can fly out underneath the vehicle and cause serious injury to person and/or damage property, when vehicle is driven at highway speeds.”
Fuel/propulsion system
8 reports
“Toyota 4 runner had a recall for the fuel pump. I have been having starting issues with it ever since. The power is good and the starter tries to turn the vehicle over. But the vehicle won't start. I have taken it to multiple locations for service through out the chicago land area. Also once the vehicle finally does start. The R.P.M.s will suddenly increase and decrease to the point that the vehicle turns off while in drive. I can provide print outs when the vehicle gets fixed, if ever. I purchased the vehicle as CPO.”
Steering
8 reports
“All of a sudden it was so difficult to steer I ended up off my driveway and almost took out my chain link fence. Two hands on left side of the steering wheel and yanked with all my strength. Then across my drive to the left. If this had happened turning onto a highway someone could have been killed.”
Structure
8 reports2 related recalls
“Noticed the frame on the passenger side of the vehicle is rusting and I’m concerned about a safety issue. I know there was a rust-related class action on earlier model Toyota’s. The rust is most prevalent on the solder joints, which has me concerned about driving safety.”
