I bought a 2005 model Optra LT (5door) in Dubai/UAE (elsewhere known as Optra5). Its exactly one year since I purchased it and I drove it only 18000 Km. One day the car broke down while starting the engine! (still under the 3 year warranty contract) This took one month of investigation and repairing by the local GM service center, ending up with complete engine re-assembling! (I mean it, as they have changed the water pump, Cylinder head & full set of 4 Pistons & Rings, 4 valves, plus Timing Belt and the time belt tightening wheel). I wrote a complain letter against the company, they explained (only verbally) that this was all because of a known problem in designing the water pump. In reply to my follow ups, after 1.5 months, they offered me 4 choices; 1) One year extension of engine warranty. 2) Replacement of the whole engine with a brand new engine. 3) Trading in the car with any other model (at the price of: original price – 20% + 10% as trade assistance) 4) Buying back the car without selling me another GM car for 35% less than the original price! (Without bothering about their fault) I am still struggling to get my rights.
Please note that this car is actually a Daewoo and has just received a few touches of design in some non-mechanical items such as exteriors and dashboard, before being introduced as a Chevrolet.
Don't think it is 100% Chevrolet, in fact it is called Daewoo Lacetti/Nubira.
This car (Lacetti/Nubira) was designed & made in Kunsan, South Korea by Daewoo's R&D department (now known as GM Daewoo Auto Technology (GMDAT)!), a company formed in 2002 out of the remnants of the bankrupt Daewoo company.
