It's the groundhog day from hell for Toyota because US owners are now complaining of unintended acceleration in cars that have been recalled and remedied.
Toyota received reports of the problem from the US National Highway Traffic Safety Administration (NHTSA) and has investigated.
A statement from the manufacturer said: 'Although these reports involve a tiny fraction of the more than one million vehicles dealers have repaired to date, Toyota takes them very seriously.'
Toyota's investigations are now being evaluated by NHTSA before the next step is taken, but the company said that it found no evidence of a failure of the throttle control system, brake override feature or in the actual work carried out during the massive recall campaign.
Toyota also says that 'many' of the complaints to NHTSA could not be verified or followed up because of a lack of owner information.
The manufacturer said it would be inappropriate to provide more specific information about its investigations since they are now being evaluated by NHTSA, but asked owners with any concerns to get in touch directly with the company.
