I saw someone steal my car and told them they hacked. Windshield wipers would slow up and down. Burning of the electrics when try to charge. Car stopping in the middle of the road. Car going on and off. The middle of the road, turning back on. Speed control messing up. Security warning going up and down.. Battery would shut on and off. Car locks going on and off. Could barely steer the car.

The AC likes to blow hot air when in the max AC setting and the temp knob being in the coldest position. Nut being the temp setting gauge comes loose causing the AC to blow hot air. Happens anytime if parked or driving.

My passenger side brake light is intermittent at best. Replaced bulbs many times, cleaned contacts, etc...but no help.on-going problem . Was rear-ended due to this exact problem. Driver side brake light fine...it is always passenger side. Many complaints about this same exact issue on-line.

Tl* the contact owns a 2002 toyota highlander. The contact stated that the security system failed and caused all of the doors to lock. The doors could not be opened manually, causing the contact to be trapped in the vehicle during extreme heat. The police department broke the rear window to release the contact. The contact felt constant weakness in the head due to the extreme heat exposure. The vehicle was not taken to the dealer to have a diagnostic test performed. The vehicle was not repaired. The approximate failure mileage was 39,050 and the current mileage was 39,106.

The heater would not provide hot air. I pushed in on the switch and the heat would work as long as I held the switch pushed in (not designed to be pushed - rotary selector). Eventually, even pressing the switch in would not work. I went on line and found a discussion blog that discussed my exact issue. I followed the recommendation and pulled the face cover off, removed the control panel and discovered exactly what had been described - a broken single strand wire that ran to the back of the switch. I attempted to make the repair using a multi-strand wire as recommended because the dealer repair option was $1,000. The heater appears to work -slightly, but now I have no AC. I think the circuit board was damaged by the soldering iron heat. Because we live in the seattle area, this causes issues with the window defogger as well as having no AC.

Air conditioner thermostat does not work properly. It swings back and forth between cold and hot without touching dial. This is very dangerous during winter where you could die if not able to get heat.

My 2002 toyota highlander had approximately 110,000 miles on it at the time when I started hearing a noise around the distributor. I took it to my mechanic (not toyota for other reasons) and he said the bearings in the distributor were going out. I called toyota (toyota of texas - grapevine) to order the part. They didn't have any in stock, so had to order from the dc. They said it would be in 4 days and to call back. Called back in 5 days and they said they had to order from hq in california and it would be in next week (ha!). Called next week. Still no distributor!! Had to order it from japan!! At that point, the regional parts manager called me and said that a highlander distributor has never gone out. I discussed my disgust with the fact that there was no distributors for a 6 year old highlander in the united states!! My mechanic was able to get with a local distributor rebuilder to try to fix it even without having the manual on the toyota distributor. He was able to rebuild it before the distributor I ordered came in 3 weeks after the initial order. In the end, my highlander sat at my mechanic's shop for 3 weeks and I was stuck renting a the whole time.

The interior heating/AC system and fan repeatedly fails to operate properly. In the spring summer when the AC would fail to blow cold and blow heat that wasn't so bad. I got the control knob fixed and all seemed to work fine. However the knob has failed again and when I needed the heat/defrost fan to work at night the frost got worse because the knob failed and the heater/fan would only blow cold air. Depending on the season and the position of the knob when it fails this should be construed as a safety issue when it affects the visual clarity of the windshield .

Ac/heat temperature control switch malfunction. This is a problem that toyota is aware of and chooses to disregard, since it tends to fail after the warranty on the new part and replacement parts expires before the problem. A small, soldered wire which connects the switch to a circuit board in the dash fails. Should be an easy fix, but toyota dealers will only replace the entire panel for $800 - 1200. This has happened twice to me on this same vehicle. First time I paid $800, the second time I got a local guy to solder the wire on the old part and replaced myself. Total cost about $10. Shame on toyota.
