"fan belt pulley" I started my truck and was leaving work driving about 10 MPH when the fan belt broke. I had power but no acceleration to the truck. Luckily I was able to coast to a full stop in the parking lot. I looked under the hood where I noticed the fan belt was broke. I had the truck towed to my accredited mechanic which he said that the shaft that holds the pulley was completely broken off inside the engine. Cost to me $600.00

"brake pads/shoes" I had to replace the brake pads and shoes due to the binding, sequeling noise they were making. As a result I had to replace the rotors due to the damage. When I first start the truck and slowly leave my driveway, I could feel the binding and hear the sequeling. After driving 20 minutes this all goes away. Repairs $500.00 which it drives 100 percent better!

"tire pressure monitor"(tpm). The tpm is always illuminating on my dash. I check my tires plus the spare every month and nothing seems to be wrong with the inflation. I still have the factory rims, with the same tire size according to manufacturer but newer with no upgrades. No damage to rims or tires ever.

"rear brake lights" lights were not working when I applied pressure to the brake pedal. I was going to work and a driver next to me informed me that both my brake lights are not working as I was at a red light. I was driving on a city street. The result was I replaced both rear brake bulbs after spending 2 hours of identifying the problem thinking it was more complicated. I always check all my lights each month making sure I am in compliance!

"cruise control" went out and I cannot find out where the problem is. The fuses are excellent. While I was driving I had the cruise control on, then all of a sudden for no reason the green illumination on the dash that let's me know it's on, was off. I tried to engage the cruise control again but that did not work. The green illumination on the dash does not come on anymore even as I attempt to engage the cruise control. I was on the highway at the time this happened.

"engine light" illuminates while driving. During the first 20 minutes of driving this light appears and stays on. Then 15 minutes later as I continue to drive with no stopping or turning off the engine, the light goes off.

Purchased vehicle new with 417 miles. From the beginning, there was a ticking noise at start-up, which gradually worsened to a loud knocking and vehicle shimmy for several seconds, sometimes requiring multiple attempts to start. Originally, it was only on cold start-up. Multiple visits to the dealer resulted in incorrect diagnoses or no diagnosis. Finally, at 18,071 miles, the problem was diagnosed as loose timing chain and worn gears. All were replaced by the dealer under warranty. Problem was significantly reduced but not solved. It then began to again worsen through multiple trips to the dealership, until 43,384 miles, when it was once more diagnosed as the timing having jumped or the chains having stretched. We declined to have the dealer replace everything with us paying for it, and had our own mechanic do the work. Our mechanic believes there is some sort of timing chain defect in design or composition, which keeps causing/allowing the chains to stretch.
