A check was performed on 13 August 2005 and the only repair was to reset the signal from scan tool. The signal remain on continuously being a dangerous situation, service shop refused initially to repair the faulty srs initiating the corrective actions were delayed for 4 (four) months so on 07 December 2005 were replaced on my vehicle both side airbags module and the sdm (sensing diagnostic module). 2. At 10000 km oil spot appear on top of the engine (engine distribution cover) and even reported to service shop mechanics no action was taken in order to investigate and to correct the failure till 40603 km when the spot extended and contaminate with lubricant timing belt area and following parts had to be replaced: ã‚â· hose, breather; ã‚â· timing belt ã‚â· timing belt expander ã‚â· oil seal ring 3. Brake, power steering, coolant and clutch fluids and spark plugs were replaced later than normal maintenance schedule, and only after I submitted a written complain to the service shop manager. It supposed to be replaced at 30 000 km and it were replaced at 38070 km. This also it happened with the fuel filter, which had to be replaced at 45000 km, and it was replaced at 49200 km. 4. It was reported by the owner that ac is out of service at 49200 km (evap condenser found with a large crack and refrigerant fluid lost completely). According to maintenance schedule at 45000 km service shop had to inspect evap condenser from the conditioning system and the pipelines. Ac periodical maintenance never had been performed to the vehicle as it was stated in the technical specifications. 5. Engine oil was not the respecting api specifications so instead 5w 30 synthetic oil was used 10w 40 mineral oil.
