What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
Very strong fuel odor inside cabin of vehicle while driving. Odor is very strong around drivers rear wheel and from the outside once parked. Smell of fuel is very strong at times while driving but seems to dissipate when driving at a faster speed I.e. On highway over 45mph.
Started vehicle and when in motion, I turned the steering wheel, the vehicle shuddered and made a loud grinding noise. Checked steering fluid, and it was below the minimum fluid level. Refilled steering fluid reservoir to proper levels and vehicle no longer made any noises or struggled to turn the steering wheel.
Check engine light periodically turns on with code p0171 usually a month in between dating back to 2015. Coinciding with the fuel smell. Inspected gas cap/filler tube for leaks as precaution but found no leak.
All of the wires going to (and inside) the headlamps have insulation cracking and falling off, exposing bare wires, with the likelihood of causing a short. I need to remove the headlamps to have then "restored", but may need to replace headlamps based on wire issue(s), at $800 per lamp.
