What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
Vehicle vibrates starting at 50mph up to 80mph. Dealer replaced tires twice plus alloy wheels replaced. Infinity mechanic admits total vibration but mfg. Rep states auto made to ride that way.
My 2000 infinity q-45 with 37,000 miles of usage suddenly and without warning completely locked up while under power in the outside lane while on a busy six lane street and would not move. The vehicle we later learned by the dealer had suffered a rear wheel brake and axle complete breakdown and failure.
Dt: contact stated that a recall 03v098000 concerning wheels came out on this vehicle before he purchased it and nothing was done to correct the problem by the previous owner or the dealer who sold it to him. The vehicle shimmied, and the tires were wearing out too soon.
While driving 25-30 mph vehicle hit a pot hole and it vibrated uncontrollably. Driver was pulled over and noticed that the rear left tire was flat. Vehicle was taken to the dealer for inspection, and mechanic determined that the tire needed to be replaced.
Transmission would shift hard while shifting from first to second gear, and vehicle would vibrate uncontrollably. Driver took the vehicle to the dealer for inspection, and mechanic could not duplicate the problem. Also, vehicle was operating as designed.
Vehicle vibrates at speeds starting at 50 mph through 80 mph. Vibration can be felt throughout cabin.
Dealership doesn't have the replacement wheels for the alloy wheel recall 03 v 098 000. Consumer has been waiting for 2 months.
When auto reaches speed of 60 mph thru 79 mph there is a vibration throughout car.
