Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“Since I am just finding out how to file a complaint I figured I would. I still have this car with me. The incident happened about 2 years ago. I was driving down the highway going to Castle Rock Colorado. When all of a sudden my car is thrown into neutral and my rpms go to 6,000. I had no way to accelerate and the car wasn't in gear to help decelerate . Since I was going down the highway at a high rate of speed trucks and cars were all around me.. I immediately turned on my four ways and pulled the car over to the side of the highway. …”

NHTSA complaint #11583000, filed 2024-04

“The vehicle has 119285 miles on it. I have started to see oil leak from the transfer-case/transmission. I called lexus back in August 2023, they were aware of certain vehicle developing oil leak problems. They issued recall on certain vehicles and issued a TSB for oil leak repair. I called lexus today and took the vehicle to the dealership. There is an understanding that my vehicle won't be covered under recall even though the problem is known to lexus. This issue may lead to unexpected breakdown of the vehicle and lead to loose of control of the vehicle.”

NHTSA complaint #11620638, filed 2024-10

“I purchased this vehicle in 2015 - it has been dealer serviced and has never been in an accident. At just under 90,000 miles on the odometer, a major fluid leak started. It turns out that the rear main (crankshaft) seal had failed, causing a leak of transmission oil. No warning lamps or messages appeared. This failure resulted in an extraordinarily expensive repair, over $2,500.00 at the dealer, Lexus of Greenwood Village (Colorado). It was not covered on warranty. …”
