Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“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.”
NHTSA complaint #11044990, filed 2017-11, 48,000 miles“Been having an issue with the brake light switch at the brake pedal sticking and our brake lights staying on. We notice it mostly after we have parked the truck and turn it off. The brake lights will stay illuminated, not always right away. The brake lights staying illuminated have caused our vehicle to have a dead battery many times. This issue with the brake light switch causing the lights to stay on has actually caused us to have to buy 2 brand new batteries in just over a 12 month period. …”
NHTSA complaint #11387619, filed 2021-01, 168,000 miles“About 3-4 days per week the truck will not start. We have to take the key out of the ignition and let the truck sit for around 10 min. And then the truck will start, or if it does start the components on the dash and the radio does not work and we have to wiggle the switch to get it to work.”
NHTSA complaint #10788690, filed 2015-11, 60,000 miles“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!”
NHTSA complaint #11044986, filed 2017-11, 68,000 miles“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.”
